The National Space and Aeronautics Administration (NASA) is enlisting help of 24 theologians as part of its efforts to determine how different religions around the world would react to contact with aliens, reported Technotrendz. A reverend is already working with NASA.

Rev Dr Andrew Davison, a British priest and theologist at Cambridge University has a degree in Biochemistry. Next year, he is releasing his book on the subject. In his book he is going to raise questions that ask how will discovery of life affect beliefs of religious people across the world.

Search for alien life has been a matter of fascination for humankind for centuries. As tools of modern science became more and more available, scientists have cast an informed gaze at the universe in search of alien life.&nbsp;

There are several candidates in our solar system itself. Scientists think that Europa, the icy moon of planet Jupiter has liquid oceans under its surface that may support life. Scientists also think that microbes exist in clouds of Venus.

Humanity is soon to get fresh 'eyes' in the sky. James Webb space telescope was launched on December 26. This will be humanity's main space telescope over the ageing Hubble space telescope. We will soon be able to see corners of universe that were unobservable to us before this. Will we find an alien spaceship flying in deep space? Time will soon tell.

NASA is hiring priests to prepare humans for contact with aliens

Researchers have discovered a hidden passageway beneath central Panama through which wind from the Earth's ''mantle'' is actively “blowing.”&nbsp;

Scientists believe that the secret passage beneath Panama holds the clue behind the reason that rocks from Earth's mantle are found over 1,609 kilometers from where they originated.&nbsp;

Located approximately 100 km below the surface of the Earth, the opening may allow a flow of mantle materials to travel all the way from beneath the Galápagos Islands.

The findings have been published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS).

Scientists believe the South American and Caribbean tectonic plates collided around 15 million years ago, causing volcanic activity that eventually formed a thin strip of land linking the Americas and separating the Pacific and Atlantic oceans.

The forging of the Americas resulted in a mass migration of animals, while the separation of the two oceans transformed the world’s climate and prompted the development of new species.

According to David Bekaert, a postdoctoral scholar in marine chemistry and geochemistry at Woods Hole Oceanographic Institution in Massachusetts, the Cocos tectonic plate is diving down and pushing oceanic crust under the continental crust of North America.

"Different sources of geological material typically have different compositions, so we can track the contribution from different regions of the mantle," Bekaert said.

The subduction of the Cocos plate under North America has the capacity to cause large earthquakes, including the 2017 Chiapas quake, a magnitude-8.1 that killed dozens.

"We found that in particular places of Central America, namely western Panama and behind the volcanic arc in Costa Rica, we have some exotic signatures [of geochemistry] that really resemble what you have in the Galápagos Islands," Bekaert said.&nbsp;

"Just beneath Panama, there is a hole, a window through the slab, that allows for the influx of this mantle component," he added.

Scientists have identified a previously unknown storm called ''atmospheric lake'' in a recent study.

The research, presented at the 2021 Fall Meeting of the American Geophysical Union, sheds light on a new type of weather condition.

Long-lived "lakes" of water vapour in the atmosphere are observed to occur over the western Indian Ocean.&nbsp;

Also see |&nbsp;<a href="https://www.wionews.com/photos/aerial-photos-show-destruction-due-to-typhoon-rai-in-philippines-438050">Aerial photos show destruction due to Typhoon Rai in Philippines</a>

The compact, slow-moving, moisture-rich pools sometimes drift west over the East African coast, bringing rain to that semi-arid area.

"The winds that carry these things ashore are so tantalizingly, delicately near zero [wind speed], that everything could affect them," says one of the researchers, atmospheric scientist Brian Mapes, from the University of Miami.

"That's when you need to know, do they self-propel, or are they driven by some very much larger-scale wind patterns that may change with climate change."

By contrast to rain-bearing "atmospheric rivers" of vapor, which are contiguous from source to the coastline at an instant, scientists call these disconnected and drifting water bodies "atmospheric lakes".

Their dynamics resemble those of a well-studied theoretical and simulation paradigm for tropical disturbances called "self-aggregation".&nbsp;

While that area's rainfall climatology is well studied on monthly basis, these vapor-mediated "storms" may have been missed as traditional meteorology tends to focus more on wind-field features and 'disturbances' as the long-lived entities of weather.

"It's a place that's dry on average, so when these [atmospheric lakes] happen, they're surely very consequential," says Mapes.

"I look forward to learning more local knowledge about them, in this area with a venerable and fascinating nautical history where observant sailors coined the word monsoon for wind patterns, and surely noticed these occasional rainstorms, too."

Researchers identify unique storm called 'atmospheric lake'

Our ideas of planets and stars are often fixated on the model presented by our solar system. In solar system, the Sun is at the centre while planets move around it in respective orbits. For many of us, this is the model for all planets and star systems in the universe. We tend to think that planets and stars are always found in nice families such as our solar system.

But universe also has those planets that do not have stars to call their own. So what do these planet revolve around? They don't. They are space nomads who roam the infinite expanse on their. An estimate says that there are billions of such planets in our galaxy alone. These planets are like ghost ships that roam the seas blindly without anyone onboard to steer them right.

Researchers from Laboratoire d'Astrophysique de Bordeaux in France have found 170 pf such rogue planets. These researchers made use of European Southern Observatory resources to make the discovery.

Rogue planets are formed when swirls of gas and dust in space forms them but just isn't enough to form their star. Another possibility is that such rogue planets may be the ones hurled outside their star systems. But these rogue planets may have a faint heat signature.&nbsp;

"We measured the tiny motions, the colors and luminosities of tens of millions of sources in a large area of the sky," says Laboratoire d'Astrophysique de Bordeaux astronomer and first author, Núria Miret-Roig. She was quoted by European Southern Observatory.

These planets have been found within the Upper Scorpius and Ophiuchus constellations. The study has been published in journal Nature Astronomy.

There are bizarre bizarre things in this world that make us go 'hmm' just to sound polite while our heads burst with genuine questions as to which thought sparked idea behind a particular invention. If lickable TV does not fall in this category according to you then just maybe your inquisitive nature needs a boost.

A Japanese professor has actually created a lickable TV screen. This TV screen can imitate flavours of food and is being touted as another step towards a 'multi sensory' viewing experience. Hmm!

The device is called Taste the TV (TTTV). It uses a carousel of 10 flavour canisters that spray in combination to create the taste of a particular food. The flavour sample then rolls on hygienic film over a flat TV screen for the viewer to try.&nbsp;

The intent behind developing lickable screen is noble.

Meiji University professor Homei Miyashita says that this kind of technology can enhance the way people connect and interact with the outside world in the era of pandemic.

"The goal is to make it possible for people to have the experience of something like eating at a restaurant on the other side of the world, even while staying at home," he said.

(The professor can be seen filling flavour canisters, Reuters image)

Professor Miyashita worked with team of about 30 students. The team has made a number of flavour-related devices. These include fork that makes food taste richer. Professor has made a prototype himself and says that commercial version would cost about $875 to make.

So who are the potential applicant who would show special interest in such a device?

The professor says sommeliers and cooks who are learning through distance education would make part of the customer base, so would be the people who want to organise tasting games and quizzes.

He also hopes to make a platform where tastes from around the world can be downloaded and enjoyed by users, much like music is now.

One Meiji student demonstrated TTTV for reporters, telling the screen she wanted to taste sweet chocolate. After a few tries, an automated voice repeated the order and flavour jets spritzed a sample onto a plastic sheet.

"It's kind of like milk chocolate," she said. "It's sweet like a chocolate sauce."

Scientists have identified a new muscle layer in the human jaw that helps it in stabilisation.

The discovery, made by researchers at the University of Basil, had previously been overlooked.

Attached to the muscular or “coronoid” process of the lower jaw, it can pull the lower jaw backward, toward the ear.

The masseter muscle is the most prominent of the jaw muscles. If you place your fingers on the back of your cheeks and press your teeth together, you’ll feel the muscle tighten. Anatomy textbooks generally describe the masseter as consisting of one superficial and one deep part.

According to lead author Szilvia Mezey from the Department of Biomedicine at the University of Basel, “This deep section of the masseter muscle is clearly distinguishable from the two other layers in terms of its course and function.”&nbsp;

The study, published in the scientific journal Annals of Anatomy, is based on a detailed analysis of stained tissue sections from deceased individuals who had donated their bodies to science.

While some historical anatomical studies describe the masseter muscle as having three layers, other individual studies from the early 2000s also reported three layers, but they divided the superficial section of the masseter into two layers and agreed with standard works in their description of the deeper section.

“In view of these contradictory descriptions, we wanted to examine the structure of the masseter muscle again comprehensively,” says Jens Christoph Türp from the University Center for Dental Medicine Basel (UZB).&nbsp;

“Although it’s generally assumed that anatomical research in the last 100 years has left no stone unturned, our finding is a bit like zoologists discovering a new species of vertebrate.”

Worms are mostly harmless. All they do is quietly&nbsp;go&nbsp;about their business&nbsp;and crawling around. But something about them gives everyone chills. Bravest among&nbsp;us have shrieked like crazy when a worm, however small, has landed&nbsp;on them out of nowhere.

We know that Earth history has crazy things involved. Forget dinosaurs, mother nature seemed to have given life to other monstrosities that may certainly have made modern human life hell.

Falls into this list a worm literally weighing 50 kg! Most modern-day snakes don't weigh as much. But hey,&nbsp;pre-historic world was a crazy place.&nbsp;

A fossil, being called that of the&nbsp;largest millipede ever has been found. Millipedes are the same worms who have probably a thousand small legs to crawl around. This one is a massive thing.

The fossil was found on a beach in Northumberland, UK. This millipede is called Arthropleura. This giant nightmare was more than 8 feet long and weighed about 50 kg. It crawled the Earth 326 million years ago.

The fossil segment was found in 2018 when a sandstone block fell on to a beach in Howick Bay. Dr Neil Davies, from Cambridge's Department of Earth Sciences says that discovery of the fossil was completely a 'fluke'. He has been quoted by BBC.

Researchers believe that the place where the fossil was found was part of a river channel millions of years ago.

It's probably good that the worm is a fossil. Nobody would like an 8-foot monster with spider-like legs crawling around.

Fun Fact: Scientists think that the fossil is not the worm itself but the exoskeleton it shed when it was growing even bigger!

We all have seen alien movies. The space-faring adventurers often encounter them somewhere in the universe. The first conversation is always gibberish, with strange noises made by the aliens that can sound anything between a frightening hum to some electronic buzz that resembles children's video games. Creative imagination runs wild when it comes to representing alien worlds.

But if a legit space noise sounded not far away from these seemingly imaginative works, it's often scary. NASA has released noises captured near Jupiter's moon Ganymede.

Ganymede is the largest moon in our solar system. It is so large that it size dwarfs Mercury, a full-fledged planet. Ganymede also has its own magnetic field, something that other moons in solar system can't boast of.

NASA's Juno spacecraft is in Jupiter's neighbourhood and making its observations. Earlier this year, Juno captured Ganymede's electromagnetic waves.

NASA has converted these waves into sound and has released what can be perhaps scientifically considered as sound of Ganymede. The eerie audio has been released. Check out

NASA releases eerie sounds captured near Jupiter's moon Ganymede

NASA's Juno Mission has captured stunning images of Jupiter's moon Ganymede.

Juno’s Ganymede Flyby has released a 50-second animation that provides an auditory as well as a visual glimpse at data collected by the mission.

According to&nbsp;Scott Bolton, Juno's principal investigator at the Southwest Research Institute in San Antonio, "This soundtrack is just wild enough to make you feel as if you were riding along as Juno sails past Ganymede for the first time in more than two decades."&nbsp;

"If you listen closely, you can hear the abrupt change to higher frequencies around the midpoint of the recording, which represents entry into a different region in Ganymede's magnetosphere."

"It is possible the change in the frequency shortly after closest approach is due to passing from the nightside to the dayside of Ganymede," said William Kurth, lead co-investigator of the Waves instrument, who is based at the University of Iowa in Iowa City, in a statement.

NASA’s Galileo spacecraft flew by Ganymede in the 1990s and confirmed the presence of an interior ocean, also finding evidence for salty water perhaps from the salt known as magnesium sulfate.

Ganymede, which with its diameter of about 3,300 miles (5,300 km), is the largest moon in the solar system and is bigger than the planet Mercury.

Ganymede boasts a lot of water, perhaps 25 times the volume of Earth’s oceans. Its oceans are estimated to be about 500 miles (800 km) deep.

Ganymede is one of five moons in the solar system thought to have oceans hidden below icy surfaces. Two other moons, Europa and Callisto, orbit the big gas planet Jupiter. The moons Titan and Enceladus circle the ringed gas planet Saturn.

According to Scott Bolton, Juno's principal investigator at the Southwest Research Institute in San Antonio, "This soundtrack is just wild enough to make you feel as if you were riding along as Juno sails past Ganymede for the first time in more than two decades."

"It is possible the change in the frequency shortly after closest approach is due to passing from the nightside to the dayside of Ganymede," said William Kurth, lead co-investigator of the Waves instrument, who is based at the University of Iowa in Iowa City, in a statement. NASA’s Galileo spacecraft flew by Ganymede in the 1990s and confirmed the presence of an interior ocean, also finding evidence for salty water perhaps from the salt known as magnesium sulfate.

Ganymede boasts a lot of water, perhaps 25 times the volume of Earth’s oceans. Its oceans are estimated to be about 500 miles (800 km) deep. Ganymede is one of five moons in the solar system thought to have oceans hidden below icy surfaces. Two other moons, Europa and Callisto, orbit the big gas planet Jupiter. The moons Titan and Enceladus circle the ringed gas planet Saturn. (With inputs from agencies)

Astronomers have issued a dire warning about the Sun and cautioned about its instability.

It comes after the eruption of the 'Dragon' star or EK Draconis, a G1.5V yellow dwarf located 110.71 light-years away from the Earth.

Scientists have highlighted that solar flares lead to mass ejections that directly affect the Earth’s environment.

''This kind of big mass ejection could, theoretically, also occur on our sun. This observation may help us to better understand how similar events may have affected Earth and even Mars over billions of years,'' said co-author Yuta Notsu from Laboratory for Atmospheric and Space Physics (LASP).

The study published in the Nature journal shows that M-type red dwarf stars are not as stable as previously thought.

However, the sun appears to be far less active than similar stars in terms of brightness variations caused by sunspots and other phenomena.

Researchers said on Thursday that an examination of 369 stars similar to the sun in surface temperatures, size, and rotation period,&nbsp;it takes the sun about 24-1/2 days to rotate once on its axis,&nbsp;showed that they displayed on average five times more brightness variability than the sun.

“This variability is caused by dark spots on the surface of the star rotating in and out of view,” said astronomer Timo Reinhold of the Max Planck Institute for Solar System Research in Germany.

The sun,&nbsp;essentially a hot ball of hydrogen and helium, is an average-sized star that formed more than 4.5 billion years ago and is roughly halfway through its lifespan. Its diameter is about 864,000 miles (1.4 million km). Its surface temperature is about 10,000 degrees Fahrenheit (5,500 degrees Celsius).

“Temperature and rotation period are thought to be the major ingredients for the dynamo inside the star, which generates its magnetic field, and eventually the number and size of the spots causing the brightness to vary. Finding such stars with very similar parameters as our sun but being five times more variable was surprising,” Reinhold said.

Elevated magnetic activity associated with sunspots can lead to solar flares, coronal mass ejections,&nbsp;large expulsions of plasma and magnetic field from the outermost part of the sun’s atmosphere,&nbsp;and other electromagnetic phenomena that can affect Earth, for example disrupting satellites and communications and endangering astronauts.

“A much more active sun might have also affected Earth on geological time scales,&nbsp;paleoclimatology. A ‘too active’ star would definitively change the conditions for life on the planet, so living with a quite boring star is not the worst option,” Reinhold said.

The researchers compared data on similar stars to historical records of the sun’s activity.

These records included about 400 years of observational data on sunspots and about 9,000 years of data based on chemical element variants in tree rings and ice cores caused by solar activity. They&nbsp;indicated the sun has not been much more active than it is now.

The findings, Reinhold said, do not rule out that the sun may be in a quiet phase and may become more variable in the future.

Barreleye fish (Macropinna microstoma) was spotted in a rare deep-sea sighting by remote-operated vehicle (ROV) of the Monterey Bay Aquarium Research Institute (MBARI) nearly 2,000 feet below ocean off the coast of California.&nbsp;

The video, which was released by MBARI on Thursday (December 9), study features of Barreleye can be seen, the most fascinating being its translucent barrel-shaped and tubular eyes.&nbsp;

MBARI revealed that during a dive with education and outreach partner, the Monterey Bay Aquarium, the team recorded the alien-like fish.&nbsp;

What makes the sighting rare? This particular species has been recorded only nine times by MBARI's remotely operated vehicles Ventana and Doc Ricketts despite logging more than 5,600 successful dives and recorded more than 27,600 hours of video.&nbsp;

MBARI noted that the barreleye lives in the ocean's twilight zone, at depths of 600 to 800 meters (2,000 to 2,600 feet), a place in oceans depths just beyond the reach of sunlight.&nbsp;

Look-wise, the fish are rather bizarre as their eyes look upwards to spot their favourite prey from the shadows they cast in the faint shimmer of sunlight from above.&nbsp;

Interestingly, MBARI researchers have learned that the barreleye can rotate its eyes beneath that dome of transparent tissue. It has also been learned that the fish are capable of directing their eyes forward, as well so that they can see the food while eating.&nbsp;

"Aquarist Tommy Knowles and his team were aboard MBARI’s R/V Rachel Carson with our ROV Ventana to collect jellies and comb jellies for the Aquarium’s upcoming Into the Deep exhibition when they spotted this fascinating fish. The team stopped to marvel at Macropinna before it swam away," MBARI revealed.&nbsp;

Scientists in the Smithsonian Astrophysical Observatory at Harvard University have discovered a ''nemesis'' of the Sun.

The study, published in the Monthly Notices of the Royal Astronomical Society, provides evidence that all stars are born in pairs.

According to astronomer Steven Stahler, "We ran a series of statistical models to see if we could account for the relative populations of young single stars and binaries of all separations in the Perseus molecular cloud, and the only model that could reproduce the data was one in which all stars form initially as wide binaries."

"Our work is a step forward in understanding both how binaries form and also the role that binaries play in early stellar evolution," he added.

In a super rare sighting, researchers have spotted a giant deep-sea jellyfish, off the coast of California with the help of a remotely operated vehicle (ROV) Doc Ricketts.

In a super rare sighting, researchers have spotted a giant deep-sea jellyfish, off the coast of California with the help of a remotely operated vehicle (ROV) Doc Ricketts. The footage showed unique and stunning details of the creature. As per a report published by Monterey Bay Aquarium Research Institute (MBARI), the rare sighting was recorded in November this year, 990 meters (3,200 feet) deep in Monterey Bay. The mysterious phantom jellyfish was first officially documented in 1899 but scientists recognised this as a new species until 60 years later. Still, scientists know very little about this animal. So far the specimen of the giant phantom jelly has been spotted just 110 times in 110 years worldwide. As mentioned by the MBARI report, their ROVs have logged thousands of dives and yet only seen this spectacular species nine times. ALSO READ | Study shows that away from human touch, tropical forests can regenerate in 20 years Features of the giant phantom jellyfish: MBARI report revealed that the bell of this deep-sea denizen is more than one meter (3.3 feet) across and trails four ribbon-like oral (or mouth) arms that can grow to more than 10 meters (33 feet) in length. It is believed that the creature lives anywhere from surface level to 21,900ft. However, it remains in an area called the twilight zone, just beyond the reach of sunlight. The researchers stated that the creature, scientifically known as Stygiomedusa gigantea, is found worldwide, except for the Arctic Ocean. It is important to note that historically, scientists relied on trawl nets to study deep-sea animals, however, the drawback was to study the jellies as they turn to gelatinous goo in trawl nets. The nets can be effective for studying hardy animals such as fishes, crustaceans, and squids. Now, the robot cams have allowed researchers to study these animals intact in their natural environment with a high-definition video.

Though there are many misconceptions, even superstitions associated with comets, they are nothing but celestial bodies that travel around the Sun in insanely big orbits.

When these icy bodies come relatively close to the Sun, the melting ice and other substances make what is known as the tail of a comet. And when they zoom past Earth, sometimes the comets are visible with naked eye.

Comet Leonard is slated to make its closest approach to Earth on December 12. It will be the brightest comet of 2021. The comet was discovered by Gregory J Leonard earlier this year.

You may want to catch a glimpse of Comet Leonard now because when it'll come to our neighbourhood again, it will be too late for all of us. If you miss it this time, you'll have to wait 35,000 years to see it again.

The comet will make its closest approach on December 12. The best time to spot it will be a few hours before dawn.&nbsp;

Where to look in the sky to spot Comet Leonard?

The comet would be visible in east-northeast part of the sky in the first weeks of December. It will pass between Arcturus, the brightest star of the Bootes constellation and the handle of the Big Dipper asterism.

After December 14, the comet can be seen in the evening sky after sunset. Astronomers say that comet Leonard will be visible till December 17.

There is no saying what the universe might throw at us. Just when some of us think they know everything about it, a new discovery tosses all that smugness out of the park.&nbsp;

Scientists have now spotted one of the smallest planets ever to be discovered outside our solar system. The planet, designated as GJ 367b is a red-hot world. It's just a bit larger than Mars and is as dense as pure Iron.&nbsp;

The planet zooms around its star every eight hours. It is 31 light-years away from Earth.

Scientists are eager to find exoplanets, as these alien worlds are known, that might harbor life. The newly discovered one, called GJ 367b, certainly could not, possessing ferocious surface temperatures and perhaps a molten lava surface on the side facing its star, they said. But other small exoplanets found and studied using the same methods might emerge as good candidates for nurturing extraterrestrial life.

A quarter century after the first exoplanet discoveries, scientists have turned toward characterizing them more precisely to gain a deeper understanding of their variety, from large gas giants akin to Jupiter to smaller rocky Earth-like planets where life might thrive.

"Gas giants such as Jupiter, as we know it, are not habitable because they have more extreme temperatures, weather, pressures and a lack of essential building blocks to support life," said astronomer Kristine Lam of the Institute of Planetary Research at the German Aerospace Center (DLR), lead author of the study published in the journal Science. She was quoted by Reuters.

"Unlike gas giants, small terrestrial worlds like Earth are more temperate and consist of important ingredients, such as liquid water and oxygen, to harbor life forms. Although not all terrestrial exoplanets are habitable, searching for smaller worlds and identifying the type of planets they are can help us understand how planets were formed, what makes a planet habitable and if our solar system is unique," Lam added.

GJ 367b is the smallest exoplanet to be so precisely characterized. It has a diameter of about 5,600 miles (9,000 km) - compared to Earth's 7,900 miles (12,700 km) and the 4,200 miles (6,800 km) of Mars. Its mass is 55% that of Earth and it is more dense - near that of pure iron.

The researchers calculated that 86% of GJ 367b is composed of iron, with an interior structure resembling Mercury, the closest planet to our sun. They are wondering whether the planet lost an outer mantle that once encased its core.

"Perhaps like Mercury, GJ 367b could have experienced an episode of giant impact which stripped away the mantle, leaving behind a large iron core. Or maybe the exoplanet is a remnant of a Neptune or super-Earth sized gaseous planet, where the atmosphere of the planet has completely blown away as the planet is blasted by a large amount of radiation from the star," Lam said.

You know what's a black box right? A box inside aircrafts which collects vital information before the plane is about to crash. As irreversible the damage in that particular air crash is, information contained in the black box sheds some major light on reasons behind the crash. Analysis of this information helps in preventing such catastrophe in future.&nbsp;

A similar sort of black box is being built for Earth. So is Earth in danger? Is it akin to an aircraft primed for a crash? Many scientists say so. While this 'crash' may not be a literal one, effects of climate change are said to have massive impact on human civilisation.

This black box is being built on western coast of Tasmania, Australia. Its mission is to 'record every step' humankind takes towards eventual destruction.

While all this business sounds gloomy, the information contained in this black box is expected to be a warning to future civilisations. In simpler terms, this may be a manual for 'how not to commit civilisational suicide'.

The black box is currently in beta stage of testing. When it's complete, this black box will be the size of a school bus with 3-inch-thick steel coating. It will have solar panels. It will also have data storage drives.

You know what's a black box right? A box inside aircrafts which collects vital information before the plane is about to crash. As irreversible the damage in that particular air crash is, information contained in the black box sheds some major light on reasons behind the crash.

You know what's a black box right? A box inside aircrafts which collects vital information before the plane is about to crash. As irreversible the damage in that particular air crash is, information contained in the black box sheds some major light on reasons behind the crash. Analysis of this information helps in preventing such catastrophe in future. A similar sort of black box is being built for Earth. So is Earth in danger? Is it akin to an aircraft primed for a crash? Many scientists say so. While this 'crash' may not be a literal one, effects of climate change are said to have massive impact on human civilisation. This black box is being built on western coast of Tasmania, Australia. Its mission is to 'record every step' humankind takes towards eventual destruction.

In simpler terms, this may be a manual for 'how not to commit civilisational suicide'. The black box is currently in beta stage of testing. When it's complete, this black box will be the size of a school bus with 3-inch-thick steel coating. It will have solar panels. It will also have data storage drives. Once activated, the black box will measure atmospheric carbon levels and temperature changes.

Scientists have identified patterns in mathematics that have never been seen before.&nbsp;

The discovery, made by the use of artificial intelligence, can help to develop fundamentally new problem-solving techniques.

The study, conducted by the University of Sydney, has been published in Nature.

According to its co-author, Geordie Williamson, ''Problems in mathematics are widely regarded as some of the most intellectually challenging problems out there.''

“While mathematicians have used machine learning to assist in the analysis of complex data sets, this is the first time we have used computers to help us formulate conjectures or suggest possible lines of attack for unproven ideas in mathematics.”

Going forward artificial intelligence will be more and more critical to reduce workload and save time.

It is also making a wide range of industrial processes more efficient, from cement production to cooling data centres.

Scientists identify new pattern in mathematics using artificial intelligence

Nebulas are places in space where stars form. Nebulas are made up of interstellar gas and dust. They are formed when old stars explode. Amd in turn, new stars are formed from the stellar material deposited in the nebula.

NASA's Hubble space telescope has captured image of Prawn Nebula, a massive stellar nursery. The nebula is 250 might-years wide and is situated at a distance of 6000 light-years away from Earth. Formally, the Prawn Nebula is called IC 4628.

The nebula has been classified as emission nebula. This is because the gas in the nebula is being ionised by stars forming inside it. This forms electrons that re-emit the absorbed energy in the form of infrared light. Human eye cannot see infrared light. And thus good-ol Hubble comes into play.

Hubble's unique vantage point in space gives it a unique advantage when it comes to clicking pictures of celestial bodies. Needless to say, its vast array of cameras and lenses makes it capable of perceiving light not ordinarily visible to human eye.

This image has been taken by Hubble's Wide Field Camera 3. The image was clicked as part of an initiative to survey large and intermediate-size stars which are in early stage of their development.

Humans have fingers to carry out tasks and sense surroundings. Animals have digits in their limbs with variety of modifications. We may be forgiven for thinking for all these years that it is just front and hind legs (or flippers, as the case may be) that enable animals, especially mammals to reach out in the surroundings.

A new study has shown that some mammals use their whiskers to sense the surroundings!

Yep those cute little things we thought added to the aww-quotient of the animals are somewhat like sensory organs.

Researchers concluded this by studying a female sea lion.

The sea lion, named Lo, took part in variety of experiments. It was found that the sea lion was receptive to the training that taught her to differentiate between objects using just whiskers.

The sea lion could differentiate between size. It could tell difference between textures. It was found that some whisker movement was involved in differentiation of colour as well.

Lo was filmed during the experiments. It was found that task-specific movements of whiskers were made by the sea lion in different tasks. It was seen that switching between different task-specific movements of whiskers enabled Lo to perform that particular task efficiently. &nbsp;

A dead star has officially smashed the record for the fastest known spin rate of a white dwarf.

Located over 2000 ight years away, the wild 'propellor' star is called LAMOST J024048.51+195226.9.

The research, published in the Monthly Notices of the Royal Astronomical Society: Letters, shows that the star's speed has broken the previous record by 29 seconds.

Plasma is getting flung out at 3000 km/second from the star which resembles AE Aquarii.

According to astrophysicist Ingrid Pelisoli of the University of Warwick in the UK, ''the star will have completed several rotations in the short amount of time that people take to read about it, it is really incredible.''

''The rotation is so fast that the white dwarf must have an above average mass just to stay together and not be torn apart.''

''It is pulling material from its companion star due to its gravitational effect, but as that gets closer to the white dwarf the magnetic field starts to dominate. This type of gas is highly conducting and picks up a lot of speed from this process, which propels it away from the star and out into space,'' he added.

Only two other types of objects,&nbsp;black holes and neutron stars,&nbsp;are more compact than white dwarfs.

Stars with up to eight times the mass of our sun are thought to be destined to end up as a white dwarf.&nbsp;

Such stars eventually burn up all of the hydrogen they use as fuel through nuclear fusion. At this point, gravity causes them to collapse and blow off their outer layers in a 'red giant' stage, eventually leaving a dense core that is a white dwarf.

White dwarfs initially have high temperatures but gradually cool over time, lacking any new energy source.

In appprocimately 5 billion years, our sun is expected to become a red giant and later a white dwarf.

Due to movies and other popular media, when we say 'dinosaur', an image of a scary, huge animal brandishing razor-sharp teeth pops into mind. This image is fitting to the fact that dinosaurs ruled every food chain and food web on Earth millions of years ago.

But a new discovery has shown that rulers of pre-humanity Earth didn't have to be oversized lizards all the time. A new species of dinosaur has been found. And guess what? It is almost the size of a dog, and had no teeth. And funny thing is, they were carnivores, that is, they ate meat.

The new dinosaur species has been found in Brazil. These tiny dinos lived 70 million years ago. Each member of this species was about three feet long and two and a half feet tall. The species has been classified as a therapod. Members of this group are believed to be carnivores. The dinosaurs had a beak-like mouth with no teeth.

The exoplanet search and study group at the Ahmedabad-based Physical Research Laboratory (PRL), has discovered a new exoplanet orbiting too close to an evolved or aging star with a mass of 1.5 times that of Sun and located 725 light years away, according to Indian Space Research Organisation.

This discovery was made using PRL Advanced Radial-velocity Abu-sky Search (PARAS) optical fiber-fed spectrograph, the first of its kind in India, on the 1.2 metre Telescope of PRL at its Mt. Abu Observatory, the Bengaluru-headquartered space agency said in a statement. Using PARAS, which has the capability to measure mass of an exoplanet, the exoplanet's mass is found to be 70 per cent and size about 1.4 times that of the Jupiter, it said.&nbsp;

These measurements were carried out between December 2020 and March 2021. Further follow-up measurements were also obtained from TCES spectrograph from Germany in April 2021, and also independent photometric observations from the PRL's 43-cm telescope at Mt. Abu.&nbsp;

The star is known as HD 82139 as per the Henry Draper catalogue and TOI 1789 as per the TESS catalogue. Hence, the planet is known as TOI 1789b or HD 82139b as per the IAU nomenclature.

The discovery team led by Prof. Abhijit Chakraborty, includes students and team members, and international collaborators from Europe and the US. This newly discovered star-planet system is very unique -- the planet orbits the host star in just 3.2 days, thus placing it very-very close to the star at a distance of 0.05 AU (roughly one tenth the distance between Sun and Mercury).There are less than 10 such close-in systems known among the zoo of exoplanets known so far.

Because of the close proximity of the planet to its host star, it is extremely heated with a surface temperature reaching up to 2000 K, and hence an inflated radius, making it one of the lowest density planets known (density of 0.31 gram per cc), it was noted.

Such close-in exoplanets around stars (with distance less than 0.1 AU) with masses between 0.25 to a few Jupiter mass are called "Hot-Jupiters". "The detection of such system enhances our understanding of various mechanisms responsible for inflation in hot-Jupiters and the formation and evolution of planetary systems around evolving and aging stars", ISRO said. This is the second exoplanet discovered by PRL (an autonomous unit of the Department of Space) scientists using PARAS at 1.2 m Mt. Abu telescope; the first exoplanet K2-236b, a sub-Saturn size at 600 light-years away, was discovered in 2018.&nbsp;

Nature is full of wonders and there's no saying what we might come across. Things once thought impossible sometimes have a way of proving us wrong. This is especially true in case of science.&nbsp;

Scientists have found a never-before-seen mineral. To add to the wonder, this mineral was found trapped inside a diamond. Existence of this mineral was known but it was also known that the mineral was found deep inside Earth's mantle.

Name of the mineral is davemaoite. It is a high-pressure calcium silicate perovskite (CASiO3). Davemaoite has a crystalline structure that is formed only under high pressure and high temperature. These conditions are found in Earth's mantle which is part between Earth's crust and core.

It is not possible to find davemaoite on Earth's surface as when the mineral travels to upper layers of Earth, it breaks down to other minerals. However, because it got trapped inside a diamond in this case, it retained its form and chemical stability.

The diamond in question was found in Botswana 660 kilometres below Earth's surface. The mineral sample was preserved within a diamond.

Study on this new mineral has been published in journal Science.

A large study has suggested that blood pressure medicines may protect against type 2 diabetes. The study has been published in medical journal Lancet.

Blood pressure medications are already prescribed by doctors worldover to reduce the risk of heart disease. However, the connection between these drugs and type 2 diabetes was previously unknown.

The study was conducted by universities of Oxford and Bristol. In this study 145,000 people were observed for 5 years. These people took part in 19 global randomised clinical trials. The researchers found that 5 mmHg reduction in systolic blood pressure resulted in reduction of risk of type 2 diabetes by 11 per cent.

In this study, researchers investigated major blood pressure drugs compared with a placebo. They found that angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) had the strongest protective effect. Both of these drug types reduced risk of developing diabetes by 16 per cent.

Other types of blood pressure-lowering drugs were not found to be as effective. Drugs like Calcium channel blockers had no effect on type 2 diabetes.

The study was funded by British Heart Foundation National Institute for Health Research (NIHR) Oxford Biomedical Research Centre and the Oxford Martin School.

They found that angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) had the strongest protective effect. Both of these drug types reduced risk of developing diabetes by 16 per cent. Other types of blood pressure-lowering drugs were not found to be as effective. Drugs like Calcium channel blockers had no effect on type 2 diabetes. The study was funded by British Heart Foundation National Institute for Health Research (NIHR) Oxford Biomedical Research Centre and the Oxford Martin School.

Blood pressure medicines may protect against type-2 diabetes

Scientists have recreated the intense pressure conditions of Earth's outer core in a laboratory.

The study, conducted by researchers at the US Department of Energy's SLAC National Accelerator Laboratory, has been published in Physical Review Letters.

Earth's inner core is under pressure about 360 million times higher than we experience in our everyday lives and temperatures approximately as hot as the Sun's surface.

According to the study's co-author Arianna Gleason, a scientist in the High-Energy-Density Science (HEDS) Division at SLAC, ''We didn't quite make inner core conditions.''

''But we achieved the conditions of the outer core of the planet, which is really remarkable.''

Earth’s magnetic field has been a life preserver, protecting against relentless solar winds, streams of charged particles rushing from the Sun, that otherwise could strip away the planet’s atmosphere and water.

"As we continue to push it, the iron doesn't know what to do with this extra stress," says Gleason.&nbsp;

"And it needs to relieve that stress, so it tries to find the most efficient mechanism to do that."

The coping mechanism iron uses to deal with that extra stress is called "twinning."

“Twinning allows iron to be incredibly strong,&nbsp;stronger than we first thought, before it starts to flow plastically on much longer time scales,” Gleason said.

Some asteroids in our solar system are massive iron objects that scientists suspect are the remnants of planetary cores after catastrophic impacts.

The researchers recreated deep-Earth conditions to see how iron copes with extreme stress.&nbsp;

Earth's neighbour Venus has the most harrowing surface conditions of all planets in the solar system. It is a 'greenhouse planet' with surface temperatures exceeding 100 degrees Celsius. Scientists and researchers are always curious as to whether Venus was ever habitable. While we have a lot of information based on out research and observations over decades, the National Aeronautics and Space Administration (NASA) is going one step ahead and sending a mission to Venus.

The DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) mission to Venus will lift off towards the end of this decade. After the launch in 2029, the mission will be carried out in two segments the spacecraft will do a couple flybys of Venus. After that, probe will be dropped into the upper atmosphere of the planet. Venus' atmosphere is 90 times denser than Earth's.

Venus' clouds are mainly composed of carbon dioxide and sulfuric acid. The probe will descend through the atmosphere and will take readings of the composition. It will also trace for signatures of Oxygen that will hint towards presence of water.

NASA has released a breathtaking video of the DAVINCI mission. Check it out

Scientists have discovered a new species of dinosaur with an extremely large nose called 'hell heron.'

The unique dinosaur with a ''bulbuous'' nasal bone has been identified by a retired researcher called Jeremy Lockwood.

The Natural History Museum in London had several collections of bones from the Isle of Wight, southern England. It is one of Europe's richest locales for dinosaur remains.

While cataloguing every iguanodon bone, Lockwood noticed the dinosaur was different from the plant-eating Iguanodon bernissartensis and Mantellisaurus atherfieldensis.

He said, ''I was convinced that subtle differences between bones would reveal a new species, so I set out to measure, photograph and study the anatomy of each bone.''

While reconstructing the skeleton of the dinosaur, Lockwood noticed that it had 28 teeth while Mantellisaurus has 23 teeth.

The study, published in the Journal of Systematic Paleontology, discusses in the herbivorous dinosaur in detail. It is about eight metres in length and weighs 900 kg.&nbsp;

''This discovery made it one of the happiest days of lockdown,'' said Lockwood.

The skeleton was found associated with one of the United Kingdom’s most complete theropods.

Lockwood said ''It seems so unlikely to just have two animals being exactly the same for millions of years without change.''

Fossils found on a rocky beach show there was double trouble on England's Isle of Wight about 127 million years ago, with a pair of large previously unknown dinosaur predators living perhaps side by side, both adapted to hunting along the water's edge.

The largest land animals in Earth's history were the sauropod successors of sauropodomorphs, as exemplified by a later denizen of Patagonia called Argentinosaurus that reached perhaps 118 feet (36 meters) in length and upwards of 70 tons.

'Hell heron': New species of dinosaur with extremely large nose discovered

The largest North American land birds have surprised scientists by giving ''virgin birth,'' as per a new study.

The research, published in Oxford Academic's Journal of Heredity, shows that critically endangered California condors have given birth through a process called parthenogenesis.

In the process, reproduction takes place without mating as female's eggs can develop into an embryo without sperm. It is also called ''virgin birth.''

Lizards, swellsharks, and water dragons are some other animals that reproduce asexually.

In birds, observation of parthenogenesis has been confined mainly to domestic turkeys and chickens separated from males.

Scientists in California started a breeding programme after the population of candors stooped to just 22 in number in 1982.

More than 1,000 chicks have been produced since the program began in 1988. By the end of 2019, the extant population consisted of 525 birds, 219 in captivity, and 306 wild individuals free-flying in California, Arizona, and Utah.

Calling the recent findings a ''eureka moment,'' Oliver Ryder, the director of conservation genetics for the San Diego Zoo Wildlife Alliance and co-author of&nbsp;the study said ''Many scientists have experiences like this when they see the world in a way they haven’t seen before.''

''I was really pleased to figure out something that was such a conundrum,'' he added.

The two offspring of the Californian candors were discovered through analysis as a part of the comprehensive genotype survey.

The discovery was surprising as the dams of both birds had each been continually housed for a number of years with a single male with which they had reproduced sexually.

The ability of a female condor to produce a male offspring via parthenogenesis has potential demographic and genetic implications. For example, this form of reproduction could assist range expansion when populations are at very low densities.

Ryder explained ''Think about it: the cases where we do know about it, it’s overwhelmingly where animals are managed in a way where females don’t have access to males. It was only because we had these detailed genetic profiles of the condor which were developed in response to the need for managing generic diversity that we discovered this.''

Reproduction without mating? Largest land birds in North America surprise scientists

Earthquakes are usually regarded with fear and though technological and scientific advances have enabled us to study the natural phenomenon in greater detail, there is still no way to predict earthquake with pinpoint precision. Major earthquakes can cause devastation to cities and earthquakes on the ocean floor can trigger tsunamis which can cause damage in even greater area.

But scientists have found that earthquakes have a positive effect as well. It has been found that earthquakes help growth of trees. Trees growing on flat ground are benefitted more than those growing on slopes like mountainsides.

Result of the study has been reported in journal JGR Biogeosciences.

The researchers led by hydrologist Christian Mohr from the University of Potsdam in Germany studied Pinus radiata trees in Chile in the aftermath of a powerful 8.8 magnitude earthquake that hit Maule region in Chile in 2010. Trees growing in valleys as well as on mountainsides were studied.

Tree core samples taken in 2014 showed that trees growing in valleys showed temporary increase in growth. The increase in growth was less among trees growing on mountainsides.

The researchers are ascribing the effect to altered grondwater streams in the aftermath of the earthquake.

Our constant search for answer to whether we are alone in the universe involves detection of water. The simple liquid has a great significance in finding life in space as it has cradled life on our very own planet. Water has been found and even predicted to be present elsewhere in out solar system but now scientists have found a galaxy that represents farthest distance from Earth where water has been found.

Scientists from University of Illinois at Urbana-Champaign have found evidence of water in a galaxy named SPT0311-58. The galaxy is 12.8 billion light-years away from Earth.

The scientists used Atacama Large Millimeter/submillimeter Array in Chile to gaze at the galaxy. The galaxy is located in younger part of the universe and it is about 780 million years old. Considering universe is 13.8 billion years old, the galaxy is fairly young.

Lead investigator of the study has been quoted in media reports as saying that evidence of presence of carbon dioxide has also been found in this galaxy. The scientists have also found that stars in this galaxy have completed their life span relatively quickly. Considering oxygen comes from dying stars, this galaxy would have oxygen too. This also logically explains presence of water.

So should we fear aliens invading Earth because their star died out? Even if they are travelling at the speed of light (300,000 km per second) it will taken 12.8 billion years to reach us. It can hence be said that we are safe for now.
