The thin and elusive atmosphere of the Moon has puzzled astronomers for centuries.&nbsp;

There is a definite lack of breathable air on the satellite, however, it does have a thin film of atoms that are found skittering along its craggy surface.&nbsp;

In scientific terms, this is called an “exosphere” which is a tenuous atmosphere that has been a topic of intrigue for all astronomers since it was first found in the 1980s.

Assistant professor in MIT’s&nbsp;Department of Earth, Atmospheric, and Planetary Sciences Nicole Nie said that unique insights have now been found in the atmosphere of the Moon.&nbsp;

The study was carried out by Nie along with her team at the University of Chicago&nbsp;and NASA&nbsp;Goddard Space Flight Centre.

<h2>Here's what scientists found about Moon's elusive atmosphere&nbsp;</h2>

The team of scientists in the research found that the atmosphere of the Moon has undergone a bombarding of the meteorites which has led to the phenomenon known as "impact vaporization."&nbsp;

In this process, the impact kicks up the lunar soil and leads to the vaporising materials which either escape to space or remain in a suspended position in the atmosphere of the moon which renews its exosphere.

"We give a definitive answer that meteorite impact vaporisation is the dominant process that creates the lunar atmosphere," said team leader Nicole Nie, an assistant professor at the Massachusetts Institute of Technology (MIT),&nbsp;in a statement.&nbsp;

"The&nbsp;moon is close to 4.5 billion years old, and through that time, the surface has been continuously bombarded by meteorites. We show that eventually, a thin atmosphere reaches a steady state because it's being continuously replenished by&nbsp;small impacts all over the moon," Nie said

"With impact vaporisation, most of the atoms would stay in the lunar atmosphere, whereas with ion sputtering, a lot of atoms would be ejected into space," she added.

<h2>Here's how the study opens avenues for exploration of Moon's atmosphere&nbsp;</h2>

Commenting on the study, lunar soils researcher at Cambridge University Justin Hu said, "The discovery of such a subtle effect is remarkable, thanks to the innovative idea of combining potassium and rubidium isotope measurements along with careful, quantitative modelling."

&nbsp;"This discovery goes beyond understanding the&nbsp;moon's history, as such processes could occur and might be more significant on other moons and asteroids, which are the focus of many planned return missions," he added.&nbsp;

The groundbreaking study has now opened a new avenue of astronomy.&nbsp;

“Without these Apollo samples, we would not be able to get precise data and measure quantitatively to understand things in more detail,” Nie said.

Bombarding of asteroids may have made Moon's atmosphere elusive, almost non-existent': Study

Sea lions, rare marine mammals are stranding themselves on the California coast. Experts believe this is hinting towards the possibility of widespread poisoning by a harmful algae bloom that occurred this summer.

The incident of stranded sea lions has been happening since July 26, as the marine mammals were found lying along the shoreline in Santa Barbara and Ventura counties, as per The Channel Islands Marine and Wildlife Institute.

The institute&nbsp;in a statement said that marine mammals are suffering from domoic acid, a neurotoxin that affects the brain. The poisoning event is largely affecting adult female California sea lions, it added.

The team has rescued 23 such animals so far. Coastal Vandenberg Space Force Base released photos of sea lions being rescued from one of its beaches.

“Rising ocean temperatures and excess nutrients are fueling these blooms, producing toxins that enter the food chain through small fish,”&nbsp;Coastal&nbsp;Vanderberg Space Force said in an Instagram caption that accompanied photos of a stranded seal being treated by wildlife officials.

“Local efforts, including monitoring and rescue initiatives, are in place to mitigate the impact.”

Outbreaks of domoic acid poisoning are common along the California coast and have caused several mass sickening incidents in recent years.

The neurotoxin is produced by a microscopic alga that proceeds through the food chain by accumulating in smaller marine animals, such as crustaceans, fish and squid, and then gets transferred to larger animals such as sea lions, dolphins and birds.&nbsp;

Experts say people can also get sickened by this acid.

The symptoms for affected animals can include disorientation, head weaving, foaming at the mouth and seizures.

Last year, hundreds of sea lions and dolphins died in the first weeks of June- it was termed a severe outbreak. At the time, marine mammal rescue workers reported receiving hundreds of calls a day about sickened animals.

While such events are naturally occurring, scientists have said that domoic acid outbreaks seem to increase in their severity, and are exploring its links to warming ocean temperatures.

“I’ve been studying domoic acid for 30 years and I have a feeling it’s getting worse based on the records we continue to break,” the executive director of the Southern California Coastal Ocean Observing System, Clarissa Anderson, told the Guardian in an interview last year.

Imagine being able to look inside a larva that is 520 million years old, with parts of the brain, internal organs, soft tissue and nervous system intact. That is what a group of&nbsp;scientists from Britain's Natural History Museum were able to do. The extremely well-preserved fossil was found in China.

It lived in the Cambrian period, known for the explosion of life on Earth. Fossils from this period will give clues into how life evolved on our green planet.

The larva belongs to a species classified as Youti Yuanshi, a prehistoric arthropod, whose current ancestores include insects, centipedes and crabs.&nbsp;

Youti is believed to have lived on the ocean floor during the Cambrian period.&nbsp;

This larva fossil from 520 million years ago is so well-preserved, scientists could see its brain

The wild facial expression of an Egyptian Mummy buried some 2,500 years ago had puzzled scientists for years, and now they appear to have found the reason. New research suggests that the woman who was mummified in ancient Egypt&nbsp;had died in extreme pain, which led her to scream so hard at the time of her demise that her face got locked in position.

Earlier it was thought that her facial expression got spoiled due to a badly done mummification. But new research by Cairo University radiologist Dr Sahar Saleem and Egyptian Antiquities Ministry anthropologist Samira El-Merghani posited that it's highly unlikely.

Based on their examinations, the researchers concluded that her body was embalmed using imported, embalmed material, meaning it was not a bad burial process that caused the deathly expression after all, according to the research published in the journal Frontiers in Medicine.

The findings were done based on new 'virtual dissections' through CT scans, scanning electron microscopy, fourier transform infrared spectroscopy and x-ray diffraction analysis.

“The mummy's screaming facial expression in this study could be read as a cadaveric spasm, implying that the woman died screaming from agony or pain,” Saleem said.

She screamed and screamed: Why was Egyptian Mummy's face so contorted? Scientists have a clue

A team of Swiss researchers have proposed using an autonomous, robotic hydraulic excavator for building a dry stone wall which will work as a blast shield and protect the launch pad on the moon.

The excavator will be using the in situ materials and the rocks from the lunar surface will be collected for making the ringed wall, which will have a radius of between 50 and 100 metres.

The scientists don't plan to adopt the costly practice of transferring the building material from&nbsp;Earth&nbsp;to&nbsp;the moon.

"The robot would be used to both collect the boulders as well as to construct the wall," said study lead author Jonas Walther, while speaking to Space.com.

The research was conducted by Walther for his master's thesis at ETH Zürich. Walther is now working with the Swiss company Venturi Lab which has been working with other companies on lunar rover design.

<h2>Lunar infrastructure - a quintessential step for humans in future?</h2>

According to scientists, the lunar infrastructure will be required if humans someday permanently settle on the moon to protect them from the exhaust and debris from rockets which are landing or taking off.

Gas, small particles and dust from rocket exhaust can prove to be hazardous, which was demonstrated when the&nbsp;Surveyor 3&nbsp;probe was brought back by the&nbsp;Apollo 12&nbsp;crew from the Oceanus Procellarum and the scientists found that it suffered damage by dust blown away by the Lunar Module Intrepid.

The scientists also fear that the rocket exhaust from&nbsp;SpaceX's giant&nbsp;Starship&nbsp;vehicle - through which astronauts will be sent on NASA's&nbsp;Artemis 3 mission - will harm the lunar environment in the area of hundreds of metres and extend it into kilometres.

Hence, they feel there is a need to set up a blast shield to protect any future ground infrastructure.

"Some dry stone walls on Earth have endured for thousands of years," said Walther, while speaking about how strong it is.

However, scientists feel that such shields won't have to last on the lunar surface for a very long time and the vastly reduced weathering on the moon means that the wall will only have to resist the blasts of rockets taking off or landing.&nbsp;

According to the estimate of the weather team, the blast shield will have to face pressure from gases released by SpaceX's Starship rockets, which will be 1,135 Pascals.&nbsp;

Space junk is quietly littering the universe above us, and a Japanese company Astroscale is on a mission to identify and remove them. Now, it has taken stunning close-ups and timelapse of an 11-metre long, 15-year-old rocket part that's quietly moving above the earth. Astrolscale plans to remove such debris in the coming years.

The spacecraft ADRAS-J, which stands for Active Debris Removal by Astroscale-Japan, had released photos of the 3-tonne rocket stage. It is suspended in microgravity and orbiting the earth.

According to the company, ADRAS-J is "the world's first attempt to safely approach, characterise and survey the state of an existing piece of large debris through Rendezvous and Proximity Operations."

Now, it has taken stunning close-ups and timelapse of an 11-metre long, 15-year-old rocket part that's quietly moving above the earth. Astrolscale plans to remove such debris in the coming years. The spacecraft ADRAS-J, which stands for Active Debris Removal by Astroscale-Japan, had released photos of the 3-tonne rocket stage. It is suspended in microgravity and orbiting the earth. According to the company, ADRAS-J is "the world's first attempt to safely approach, characterise and survey the state of an existing piece of large debris through Rendezvous and Proximity Operations." Sometimes, you need to look at space debris from a different perspective.#ShowtheWayADRASJ pic.twitter.com/XSFG2PUgOC — Astroscale (@astroscale_HQ) August 1, 2024 × Watch: Mercury's Diamonds: What lies beneath the planet's crust?

NASA issued a double warning as two massive asteroids rushed towards Earth at a scary speed to make a close flyby on August 1.&nbsp;

NASA’s Jet Propulsion Laboratory said that the asteroids - 2024 OE and 2024 OO - are not an immediate threat to Earth and are likely to pass by the planet&nbsp;silently.&nbsp;

The sizes of the two asteroids, 2024 OE and 2024 OO, are 190 feet and 88 feet in diameter, respectively, which is roughly as big as a commercial aeroplane.

The larger asteroid is expected to pass by Earth at a safe distance of about 1.26 million miles and the smaller one at a&nbsp;distance of 925,000 miles.

The skies will witness a rare celestial event on August 14 when Mars and&nbsp;Jupiter&nbsp;will align with each other in conjunction.&nbsp;

In the breathtaking event, the two planets will be only a third of a degree apart, which is less than the width of a full Moon, according to NASA.

No special equipment will be required for the observers to see both&nbsp;Mars&nbsp;and Jupiter in the eastern direction for nearly an hour before sunrise on August 14.

At the end of the sunrise, the conjunction of Jupiter and Mars will be joined by the Moon, which will appear next to Jupiter and above Mars, adding to the celestial spectacle. This conjunction will also be visible on August 27 for an hour before sunrise.

<h2>Why does a planetary conjunction occur?</h2>

A planetary conjunction happens in the sky when two planets get positioned very closely from the perspective of Earth. This occurs because the planets align along the same line of sight, even though they are at a distance of millions of kilometres in space.

From the viewpoint of astronomical events, August has been an important day. The&nbsp;Perseid meteor shower is likely to peak on August 11 and allow viewers to see around 50 to 70 meteors per hour.

Generally, the Perseid meteor shower peaks in mid-August after emerging from the constellation Perseus.&nbsp;

NASA said that the origin of the Perseid meteors lies in the comet 109P/Swift-Tuttle - which completes one orbit of the Sun every 133 years.

When Earth crosses the debris trail, the rocks strike the atmosphere of the planet and a meteor shower happens.

In a new study carried out by the chemists from&nbsp;Harvard University, it has been found that the first building blocks of life landed on Earth a bolt of lightning.&nbsp;

To make the stunning scientific revelation, the team made an attempt to reenact what may have occurred millions of years ago on Earth in their laboratory. &nbsp;

In this experiment, the scientists made a stunning discovery of cloud-to-ground lightning.

<h2>Origin of life puzzles scientists</h2>

Scientists have remained puzzled over how the origin of life took place on Earth. In their attempt to solve the jigsaw, they have come up with various possibilities of how life started to mushroom on Earth.&nbsp;

In this cosmic theory of the origin of life, it has been believed till now that the vital materials were deposited by comets or asteroids on the surface of Earth and that lightning struck the clouds which led to the creation of life.

However, when the scientists inspected these theories, the chances of such cosmic events leading to the creation of life seemed less likely and collisions from space objects appeared to have a rare chance.&nbsp;

Also, the lightning zapping between clouds appeared to the scientists to be an inefficient method for producing the&nbsp;necessary materials.

<h2>Cloud-to-ground lightning strikes behind the genesis of life?</h2>

Among these uncertainties, the scientists at Harvard University started exploring how cloud-to-ground lightning strikes may have led to the genesis of life.

To validate their new hypothesis, the scientists made their lab into a mini early Earth. The lightning strikes were stimulated across air, water, and land replicas which were kept in a controlled environment.

The scientists studied the products which were formed in these experiments. In their findings, the scientists discovered that both carbon and nitrogen went through a transformation into&nbsp;molecules which are likely early building blocks of life.

It was observed by the scientists that carbon morphed into formic acid and carbon monoxide and nitrogen turned into nitrite, nitrate and ammonium.

The researchers also added some rocky elements in the experiment and the minerals which are found on the landscape of Earth.&nbsp;

The experts observed a spike in ammonia production which is a molecule important for&nbsp;life on our planet.

Anybody who watched the Jurassic Park series of movies would believe that dinosaurs roamed rainforests. But that's far from true, according to scientists. The reason? Rain forests did not exist till much after the dinosaurs were wiped off the earth in an extinction event that is thought to have happened when an asteroid hit the planet.

Palaeobotanists say the rainforests that we see today came into existence centuries after the cataclysmic events that led to the extinction of dinosaurs.

An article in The Smithsonian magazine noted that in fact, it was the destruction of non-flying dinosaurs that allowed the rainforests to form and thrive.

"Paleobotanists have found that Earth’s earliest rainforests only sprang up in the wake of the terrible asteroid impact that ended the Cretaceous," said the article.

It is normal for Earthlings to expect the Moon to shine high in the night sky but what if it disappears after drifting away from the Earth?&nbsp;

A new study has found that the Moon is slowly moving away from the Earth and it is likely to change the relationship between the planet and its only natural satellite.

<h2>How is the drifting of the Moon impacting Earth?</h2>

According to scientists, the drifting of the Moon has been impacting the length of days on Earth, although at a very slow rate.

As the Moon continues to move away from the Earth in a span of millions of years, it is making an average day's length longer.

A team at the University of Wisconsin-Madison carried out a study in which they focused on how rocks were formed 90 million years ago.&nbsp;

In this study, the scientists analysed the interactions of Earth with the Moon nearly 1.4 billion years ago.

It was found that the Moon is going 3.82 centimetres away from Earth every year. This will eventually lead to Earth days extending to 25 hours after 200 million years.&nbsp;

Professor of geoscience at the University of Wisconsin-Madison Stephen Meyers said, “As the moon moves away, the Earth is like a spinning figure skater who slows down as they stretch their arms out.”

“One of our ambitions was to use astrochronology to tell time in the most distant past, to develop very ancient geological time scales," he added.

“We want to be able to study rocks that are billions of years old in a way that is comparable to how we study modern geologic processes," Meyers said.

Moon is going far away from the Earth. Will it disappear soon from night sky?

Humans and human-made disasters are constantly threatening an increasing number of creatures, some of which have inhabited the Earth far longer than our species. Some species like the Sumatran Rhino are gone forever, but scientists may have a way to save the remaining endangered creatures for future generations. How, you may ask? Four words: Tissue banks on the Moon.

Setting up a biorepository on the Moon will have many advantages.

Firstly, low temperatures are needed to preserve biological samples. The lunar surface naturally boasts frigid temperatures of -196ºC, necessary to preserve the samples in a way suitable for future cloning.

Additionally, the Moon can keep the samples even if something were to happen to our planet. For example, a doomsday seed bank in Ukraine was destroyed in 2002 during the ongoing Russia-Ukraine war.&nbsp;

Another seed bank, the Svalbard Global Seed Vault on a remote Norwegian island in the Arctic Circle that provides frozen storage of seeds to ensure important food crops can be re-established if wiped out by disease or drought, was recently threatened by flooding because of warm temperatures.&nbsp;

Humans and human-made disasters are constantly threatening an increasing number of creatures, some of which have inhabited the Earth far longer than our species.

Humans and human-made disasters are constantly threatening an increasing number of creatures, some of which have inhabited the Earth far longer than our species. Some species like the Sumatran Rhino are gone forever, but scientists may have a way to save the remaining endangered creatures for future generations. How, you may ask? Four words: Tissue banks on the Moon. Moon to the rescue An international team of scientists has raised concerns that threats like climate change and habitat loss due to human activities have far outpaced humanity's ability to protect the many species on the verge of extinction. They suggest that the solution to this massive problem may lie outside our planet…on the moon to be exact.

Lunar lifeboats: Scientists suggest ultimate backup plan to save Earth’s endangered animals

Scientists have found two never-before-seen groups of microbes that live in the hot springs of Yellowstone National Park,&nbsp;United States. The discovery, made by researchers from Montana State University, was published in the journal Nature on July 24.&nbsp;

The study, titled, "Cultivation and visualization of a methanogen of the phylum Thermoproteota", revealed that the new microbe groups are dubbed Methanomethylicia and Methanodesulfokora. They are methanogens, single-celled organisms that produce methane.&nbsp;

Methanogens, known to science since 1933, are methane-producing bacteria, especially an archaean which reduces carbon dioxide to methane, unlike humans and other animals who eat food, inhale oxygen and exhale carbon dioxide to survive.&nbsp;

The findings of the research may have implications for the search for extraterrestrial life and the fight against climate change.&nbsp;

It was earlier believed that all bacteria that produced methane belonged to a single phylum called Euryarchaeota. Now, the discovery of the two new microbial groupings confirms that methane-producing microorganisms are more diverse. They were previously only identified from DNA samples.&nbsp;

Methane is a gas that is 28 times more potent than carbon dioxide when it comes to trapping heat in the atmosphere.&nbsp;

In a statement, microbiologist Roland Hatzenpichler of Montana State, an author of the paper, said: "All we knew about these organisms was their DNA. No one had ever seen a cell of these supposed methanogens; no one knew if they actually used their methanogenesis genes, or if they were growing by some other means."&nbsp;

Two distinct study groups—one from China and the other from the US—have succeeded in cultivating these microorganisms in the lab, confirming that they actually produce methane.&nbsp;

The finding is significant as methanogens produce 70 per cent of the world's methane, with Hatzenpichler saying: "Methane levels are increasing at a much higher rate than carbon dioxide, and humans are pumping methane at a higher rate into the atmosphere than ever before."&nbsp;

Scientists are still trying to find out whether Methanomethylicia in non-extreme conditions grows by using methanogenesis or if they use some other mechanism.&nbsp;

They may be able to change the circumstances in their habitats and reduce the amount of methane released into the atmosphere if they comprehend this.&nbsp;

"My best bet is that they sometimes grow by making methane, and sometimes they do something else entirely, but we don't know when they grow, or how, or why. We now need to find out when they contribute to methane cycling and when not," Hatzenpichler said.&nbsp;

Unusual organisms found in hot springs of Yellowstone National Park might help in search for alien life

Researchers have found that in the United States, several dark chocolate products are contaminated with lead and cadmium, two highly toxic metals. The study was led by scientists at George Washington University and published Wednesday (Jul 31) in the peer-reviewed Frontiers in Nutrition.&nbsp;

Researchers have analysed over 70 dark chocolate products from retailers such as Whole Foods Market, Amazon and GNC. They tested the products in order to check whether or not heavy metals lead, cadmium or arsenic were present in them. None were tested above the maximum contamination level.&nbsp;

The study was carried out using samples over a period of eight years from 2014 to 2022. Notably, the researchers have not disclosed product names.&nbsp;

Also read:&nbsp;<a href="https://www.wionews.com/science/study-shows-strong-links-between-losing-loved-ones-and-ageing-745671">Study shows 'strong links' between losing loved ones and biological ageing</a>&nbsp;

The study discovered that 43 per cent of the goods tested had levels of lead contamination that were above permitted standards, and 35 per cent had levels of cadmium contamination as per California law's permissible limits for heavy metals in food.&nbsp;

"The amount of lead that was found, in general, was not alarming. But most people probably don't have a great handle on what their heavy metal exposure is," Leigh Frame, the co-lead author of the study and the executive director of the office of integrative medicine and health at George Washington University.&nbsp;

Frame noted that food researchers often use the 1986 regulations as a safety standard because the US Food and Drug Administration (FDA)&nbsp;doesn't set limits on heavy metals in most foods. Notably, the FDA&nbsp;does have suggested limits for chocolate and sugar-based candy but only for children.&nbsp;

The threshold for heavy metals in foods is 0.5 micrograms a day as per California guidelines. Researchers have found that the levels of lead and cadmium in chocolate samples varied from 0.29 to 14.12 microgrammes per daily serving, with 4.1 microgrammes per day being the maximum permitted.&nbsp;

The study revealed that lead levels in the samples ranged from none to as high as 3.316 microgrammes per daily serving, with 0.5 microgrammes per day as the maximum allowed per California guidelines.&nbsp;

The researchers also discovered that the levels of contamination in organic items were higher, but they were unable to ascertain how the metal contaminations entered the chocolate products.&nbsp;

Frame said, "You actually cannot avoid exposure to heavy metals in the diet. It's really not about avoiding them; it's about making sure you're not getting too much."&nbsp;

The Sun is approaching its&nbsp;maximum which is leading to more solar flares and stronger geomagnetic storms hitting the Earth. In its 11-year-long cycle, the Sun reaches the peak of its activity which is called "approaching the maximum".

When it reaches the maximum, the Sun has more sunspots which releases more flares towards the Earth. These sunspots are comparatively colder regions on the surface of the Sun with especially intense magnetic field.

These extreme magnetic regions emit coronal mass ejections (CMEs) and solar flares. CMEs are huge waves of plasma (electrically charged particles) which are emitted by the Sun in interplanetary space at high speed.

In the world of science fiction, flying cars have long been a dominant feature as humans have wondered when they will become a part of our real life.

However, now with the invention and successful testing of flying taxis, flying cars do not appear as a dream but something that will soon turn into reality.

A flying taxi, which was powered by hydrogen, covered a record 561 miles (902km) when it flew over&nbsp;California.

This flying car has been created by Joby Aviation and has been fueled by hydrogen which means it does not produce any emissions apart from the water vapour.

Speaking about the flying car, founder and CEO of Joby JoeBen Bevirt said, "Imagine being able to fly from San Francisco to San Diego, Boston to Baltimore, or Nashville to New Orleans without the need to go to an airport and with no emissions except water. That world is closer than ever."

<h2>All about the flying taxi&nbsp;</h2>

The US military had partly funded the air taxi which is powered by six propellers that gave it the ability to take off as well as land vertically like a helicopter.

Once the taxi takes off, its propellers rotate from a vertical to a horizontal position that allows the taxi to fly ahead similar to a traditional fixed-wing aircraft.

The taxi's adaptable capacity allows it to accommodate four passengers at a speed of 200 miles per hour (322kmph) or when flying in urban areas.

It is not the first time such an aircraft has been flown but this aircraft is unique because it is hydrogen which powers these propellers.

This spacecraft is an original all-electric aircraft's modified version which has been designed by Joby and has covered 25,000 miles (40,000 km) of test flights.

NASA has issued&nbsp;warning after they spotted a 150-foot (46-metre) asteroid&nbsp;named 2024 NS1, hurtling towards Earth at a threatening speed of 27,274 km/h.&nbsp;

The asteroid, which is almost the size of an aeroplane, will make its closest approach to Earth on August 2 at 00:05 UTC (5:35 IST).&nbsp;

Asteroid 2024 NS1 has been classified as an Apollo asteroid, which is part of a group of near-Earth objects (NEOs) whose orbits cross the path of the Earth.&nbsp;

Archaeologists unsealed a 2,000-year-old sarcophagus during the investigation of the "Tomb of Cerberus". The discovery also included a remarkably well-preserved body wrapped in a shroud.&nbsp;

The archaeologists found the chamber tomb within cultivated land situated in the municipality of Giugliano in Campania, near Naples, Italy in 2023. Ever since, they have been examining the tomb with microcameras.&nbsp;

The research team was led by Dr Simona Formola, who found the "supine inhumed" body. The remains belonged to someone who was in an "excellent state of conservation", a translated statement noted. &nbsp;

Archaeologists said that the remains have been preserved by plant-based creams that were applied over the bodies before they were sealed. The climatic conditions of the burial chamber could have aided the process of that person's preservation. The shroud was also mineralised.&nbsp;

The mummified person was accompanied by several objects, including ointment jars and other things which are often used to clean the body during burial.&nbsp;

The perfect preservation suggests that the person could have been related to the individual for whom the tomb was being constructed. However, the research team has been examining the preserved body to understand whether or not the individual had a privileged upbringing.&nbsp;

Last year, archaeologists were led to the unsealed tomb during excavations at the necropolis border. They came across many frescoes across the untouched chamber's ceilings. The walls were found in pristine condition.&nbsp;

A stunning fresco of Cerberus, the three-headed hound from Greek mythology believed to be the protector of the underworld, graced the tomb's entrance. It is said that the multiheaded beast keeps the dead from escaping from hell's vengeance.&nbsp;

In a statement, superintendent Mariano Nuzzo said: "In recent months, in fact, laboratory analyses conducted on samples taken from the inhumations and the depositional beds have returned a considerable amount of data on the treatment of the deceased’s body and the funerary ritual carried out, significantly enriching the panorama of our knowledge."&nbsp;

Elon Musk's SpaceX is gearing up to take its first step in the world of space tourism.&nbsp;

The company, in a press conference, said that its Polaris Dawn mission will be launched on August 19 and fintech billionaire Jared Isaacman will be taken into space for a private spacewalk - the first one to be held in the world.&nbsp;

The Polaris Dawn mission went through various rescheduling&nbsp;and its date July 31 was again postponed to August 19.&nbsp;

The date was postponed after the rockets of the company exploded in July, although the official reasoning which led to the blast was said to be traffic-related.

During the press conference, the director of SpaceX's Dragon mission management Sarah Walker said, "There's a lot going on on [the International Space Station] right now. We opted to fly the Crew-9 mission as our next [astronaut] mission and are ready to fly Polaris Dawn in late summer, as soon as we fulfill those obligations."

Isaacman has earlier flown on a SpaceX rocket when he went on an&nbsp;incredibly expensive orbital vacation&nbsp;in 2021.&nbsp;

This is not the first time a mission has missed the launch dates. According to Space.com, Polaris Dawn was earlier scheduled to be launched in 2022, however, it was time and again pushed back.&nbsp; 
Considering the official reason for the postponement, it is not clear if the most recent postponement happened because of the Falcon 9 explosion or not.

Sorrow, anguish, heartbreak, agony, heartache: these words are synonymous with bereavement, which means grieving the loss of a loved one. Such a devastating loss is life's most stressful event and can lead to a major emotional crisis. The latest study has attempted to establish a connection between grief and biological ageing.&nbsp;

<h2>What is biological ageing?</h2>

It refers to how old your cells and tissues are based on physiological evidence. A gradual decline in cells, tissues and organ function leads to a higher risk of chronic diseases. Biological ageing is different from chronological age, which is the number of years a person has been alive.&nbsp;

Researchers at Columbia University's Mailman School of Public Health and Butler Columbia Aging Center researchers carried out the study and discovered that the ones who lost a parent, partner, sibling, or child showed signs of accelerated biological ageing.&nbsp;

"Few studies have looked at how losing a loved one at different stages of life affects these DNA markers, especially in study samples that represent the U.S. population," Allison Aiello, PhD, the James S. Jackson professor of health longevity in Epidemiology and the study's lead author said in the press release.&nbsp;

"Our study shows strong links between losing loved ones across the life course from childhood to adulthood and faster biological aging in the US," the author added.&nbsp;

The research, published in JAMA Network Open, suggests that the impact of loss on ageing can be seen long before middle age. The state may also contribute to health differences among racial and ethnic groups.&nbsp;

According to Aiello, there still is so much to do when it comes to understanding the possible impact of losing loved ones in different phases of our DNA markers.&nbsp;

The researchers divided the losses into two categories: those that happened in maturity (ages 19 to 43) and those that happened during childhood or adolescence (up to age 18).&nbsp;

"People who experienced two or more losses had older biological ages according to several epigenetic clocks. Experiencing two or more losses in adulthood was more strongly linked to biological aging than one loss and significantly more so than no losses," the press release said, &nbsp;

"The connection between losing loved ones and health problems throughout life is well-established. But some stages of life might be more vulnerable to the health risks associated with loss and the accumulation of loss appears to be a significant factor," Aiello noted.&nbsp;

Study shows 'strong links' between losing loved ones and biological ageing

A new study has revealed that a common parasite found in cat poop could be a catalyst in the treatment of neurological disorders such as Alzheimer's and Parkinson's.&nbsp;

The study, titled "Engineering Toxoplasma gondii secretion systems for intracellular delivery of multiple large therapeutic proteins to neurons", was published in Nature Microbiology on Monday (Jul 29).&nbsp;

Researchers have found that Toxoplasma gondii, a parasite commonly present in feline litter, successfully introduces proteins into the mouse brain.&nbsp;

The study, conducted by international researchers led by the University of Glasgow, in collaboration with Tel Aviv University, is still in its early phases. However, it provides a promising glimpse at how researchers can overcome one of the most difficult obstacles in neurological treatment.&nbsp;

Previously, researchers faced challenges in getting specific medication over the blood-brain barrier and into the correct location inside neurons, but the latest groundbreaking discovery provides an exciting new field of research. It is believed that the parasite, Toxoplasma gondii, can cross this barrier.&nbsp;

Researchers have noted that it would take several years to&nbsp;practical application of the findings.

Parasites found in cat poop could help treat Alzheimer's and Parkinson's: Study

In the genomes of the human body, some of the zombie viruses - which have been handed over from foreign DNA and passed to humans through generations - remain hidden and unnoticed.&nbsp;

It was believed for a long time that they were inactive, but recent studies have suggested that these sequences of genes have the capability of wreaking havoc.&nbsp;

The researchers, headed by University of Colorado bioinformatician Atma Ivancevic, discovered that cancers can make use of some of these zombie&nbsp;virus&nbsp;parts for their growth.&nbsp;

Genome biologist and senior author Edward Chuong said, "Our study shows that diseases today can be significantly influenced by these ancient viral infections that until recently very few researchers were paying attention to."

These ancient genes, which were earlier dismissed as 'junk' DNA, are snippets of virus leftovers called endogenous retroviruses&nbsp;(ERVs) which are important for the existence of mammals because they spurred the&nbsp;evolution of the placenta.&nbsp;

However, not everything about ERVs is helping in the existence of humans.&nbsp;

"We know that&nbsp;cancer&nbsp;cells express a lot of genes that are not supposed to be on, but no one really knows what is turning them on. It turns out many of the switches turning them on are derived from these ancient viruses," said Chuong.

<h2>How did the researchers find that ancient genes are pushing cancer?</h2>

The datasets on the epigenomes of 21 types of cancer were analysed by Ivancevic and her team, who stumbled upon a particular family of ERV called long terminal repeat 10 (LTR10) which was found to be active at very high levels. The researchers found that our primate ancestors were infected by the original virus around 30 million years ago.

The researchers carried out a functional study on a cell line of colorectal cancer tissues in which it was found that the expression of genes was regulated by LTR10 with established roles in the generation of tumours.

The undead LTR10 genes were taken out of action in human colorectal tumour cells and in mice, the genes which are known to lead to the growth of cancer, including XRCC4, were deactivated.&nbsp;

In the genomes of the human body, some of the zombie viruses - which have been handed over from foreign DNA and passed to humans through generations - remain hidden and unnoticed.

In the genomes of the human body, some of the zombie viruses - which have been handed over from foreign DNA and passed to humans through generations - remain hidden and unnoticed. It was believed for a long time that they were inactive, but recent studies have suggested that these sequences of genes have the capability of wreaking havoc. The researchers, headed by University of Colorado bioinformatician Atma Ivancevic, discovered that cancers can make use of some of these zombie virus parts for their growth. Genome biologist and senior author Edward Chuong said, "Our study shows that diseases today can be significantly influenced by these ancient viral infections that until recently very few researchers were paying attention to." These ancient genes, which were earlier dismissed as 'junk' DNA, are snippets of virus leftovers called endogenous retroviruses (ERVs) which are important for the existence of mammals because they spurred the evolution of the placenta.

"We know that cancer cells express a lot of genes that are not supposed to be on, but no one really knows what is turning them on. It turns out many of the switches turning them on are derived from these ancient viruses," said Chuong. How did the researchers find that ancient genes are pushing cancer?

Zombie viruses hidden in ancient genes may have accelerated cancer: Study

Forever chemicals, a group of dreaded pollutants,&nbsp;are being found in all kinds of places, even inside human wombs. But imagine a simple solution: A 100 per cent 'cleanup' using LED lights. Is that even possible?

If an experiment made by scientists in Japan is an indication, LED light exposure along with a cocktail of chemicals can isolate, separate and remove the dangerous parts in forever chemicals, scientifically called Per- and polyfluoroalkyl substances or PFAS.

Also read:&nbsp;<a href="https://www.wionews.com/science/comet-of-the-century-is-set-to-blaze-past-earth-heres-how-you-can-watch-it-with-naked-eyes-745504">‘Comet of the century' is set to blaze past Earth. Here's how you can watch it with naked eyes</a>

The researchers reportedly managed to 'clean up' the forever chemicals at room temperature, and that too overnight, or just eight hours to be precise.

<h2>Cleaning up forever chemicals with LED: How it works&nbsp;</h2>

For the experiment, researchers at Japan’s Ritsumeikan University used a&nbsp;mixture made of cadmium sulfide nanocrystals, triethanolamine and water. The forever chemicals were then put into this mixture, and exposed to LED lights of 405-nanometer wavelength, burning at around 100 degrees Fahrenheit temperature.

The PFAS used in this experiment were perfluorooctanesulfonate or PFOS.

The aim was to start a photocatalytic reaction that eventually breaks down and separates the fluorine irons of the forever chemicals. The experiment proved to be a success, as per a report in New Atlas.

Not only was the separation and removal of these pollutants done, but the chemical process also freed up some parts of the dreaded PFAS that can be put to good use. These are fluorine ions, which can be used for industrial products.

<h2>What are 'forever chemicals or PFAS'?</h2>

PFAS is the name given to a bunch of chemicals that are resistant to water and extreme heat.

This is possible because of the presence of carbon-fluorine bonds in them.

While they are used in a number of products like water-proof cloths, non-stick cookware and foam used by firefighters, their very resilient qualities also make them dangerous. They are resistant to heat and would require at least 400 degrees Fahrenheit to burn. This makes their disposal near-impossible. PFAS are generally buried in landfills to prevent their further exposure.

Once ingested, they can stay in the human body 'forever', hence the name forever chemicals.

LED lights in room temperature can 'clean up' forever chemicals overnight, suggests study

Comet C/2023 A3 or Tsuchinshan-ATLAS, which has been given the title of &nbsp;‘comet of the century' is set to come very close to Earth in autumn 2024.&nbsp;

When it approaches the Earth, it is likely to have a bright, beautiful and long tail as it passes by the Sun at a distance which is similar to the orbit of Mercury. During this time, the ice over the comet will evaporate, a large amount of dust will cover it and it will have the brightest tail.&nbsp;

<h2>When and where the comet will be visible?</h2>

The space observatories first spotted the comet in early 2023 in&nbsp;China&nbsp;and South Africa. This time it will be approaching Earth on October 12, which is the International&nbsp;Astronomy&nbsp;Day.

When it comes closer, the comet will appear&nbsp;as bright as the stars. If it deteriorates, its lustre will be lost and it will become&nbsp;difficult to be viewed by the human eye.

Comet C/2023 A3 will be clearly visible in the Northern Hemisphere. In 1997, Comet Hale-Bopp was also spotted in this hemisphere.&nbsp;

The comet is expected to be visible in November evenings at 4.5-8 magnitude and will rise higher in the Northern Hemisphere after sunset.

The comet should be visible at 8-10 magnitude in December. Gradually it will move closer to the Sun and move above the horizon.&nbsp;

<h2>How can you watch the comet?</h2>

It is not required to travel to distant places to watch this comet. People can log in to the 'Sky Tonight' app to watch Comet C/2023 A3 or Tsuchinshan-ATLAS.&nbsp;

In the application, the current position of the comet can be seen for the location. The device needs to be pointed to the sky and the white arrow has to be followed to the spot of the comet.&nbsp;

Astronomers are worried the comet might be breaking up and will crumble before it hits the perihelion which should happen sometime before September 27 when it makes its closest approach to the Sun.&nbsp;

Because of gravitational forces and solar radiations, the comets&nbsp;disintegrate.

‘Comet of the century' is set to blaze past Earth. Here's how you can watch it with naked eyes

A rare canvas of rock art has been discovered hidden in the caves of Colombia's Amazon forest which tells us a different tale of early settlers.

The canvas of human history was found in the wilderness of the forest by an international team of researchers from the&nbsp;Universidad Nacional de Colombia, Universidad de Antioquia and the&nbsp;University of Exeter.

The cave is located in the Serranía de la Lindosa, Cerro Azul which is a tabletop hill near the Guayabero River and has been an important part of the early humans who were in the Amazon.

On this hill are hidden multiple rock arts which serve as a testament to the beliefs and lives of the early settlers of the region.&nbsp;

Associate Professor in Exeter’s Department of Archaeology and History Dr Mark Robinson said, “These rock art sites include the earliest evidence of humans in western Amazonia, dating back 12,500 years ago. As such, the art is an amazing insight into how these first settlers understood their place in the world and how they formed relationships with animals.”

<h2>Rock art reveals animals were not just dinner dishes of human but...</h2>

The detailed study of animal remains found in the excavations was carried out by the team and the artistic depictions were analysed which revealed an intriguing discrepancy.

Although the remains of the animal suggested that humans lived on various animals like mammals, reptiles, and even fish, it looked like the artists were not just painting the animals served on the dinner table.&nbsp;

The researchers observed that the images of animals and humans suggested some species were revered and said to possess supernatural connections, which may have given birth to complex rituals.&nbsp;

Dr. Javier Aceituno, who is from Universidad de Antioquia, Medellín, said, “The Indigenous people of Cerro Azul and the surrounding lands hunted and depicted a diverse array of animals from different ecologies – from aquatic fish to arboreal monkeys; terrestrial deer to aerial birds, both nocturnal and diurnal."

He added, “They had intimate knowledge of the various habitats in the region and possessed the relevant skills to hunt animals and harvest plants from each, as part of a broad subsistence strategy.”
