<p>Humans have been making plans to make Mars their home someday and billionaire Elon Musk has already expressed his wish to colonise&nbsp;Mars by 2050.</p>

<p>According to the scientists, Martian dust would be injected into the atmosphere of the planet in large quantities to&nbsp;improve its ability to trap heat, like carbon dioxide and water vapour are captured on Earth.</p>

<p>The scientists will shoot nearly 10 litres of dust, filled with iron and aluminium, every second for nearly a decade to change its temperature from -85F to 86F.</p>

<p>Musk had earlier said that he was planning to use the natural resources on Mars for "terraforming" its atmosphere and turn it into a wetter and warmer planet.</p>

<p>"It’s not that often you get some really quite new, innovative idea for terraforming," said Colin McInnes, who is a space engineer at the University of&nbsp;Glasgow, while speaking to Science Magazine.&nbsp;</p>

<p>The polar vortex of Antarctica is on the verge of splitting in two for the first time in more than two decades because of a sudden increase in stratospheric temperatures.&nbsp;</p>

<p>The traffic lights on the roads may not appear as they used to any more. For more than a century, the traffic lights have been known to have only three colours - red, amber and green.&nbsp;</p>

<p>However, they are now likely to have a fourth colour after scientists suggested that adding another colour will help traffic flow near driverless vehicles.&nbsp;</p>

<p>Autonomous vehicles&nbsp;(AV) are a new concept and no completely driverless cars have made it to the road yet.&nbsp;</p>

<p>Self-driving taxi firm Waymo is close to finalising what is called SAE4 in California and Arizona&nbsp;and other companies like Tesla are also producing self-driven vehicles.&nbsp;</p>

<p>As of now, the government has not allowed self-driven vehicles on UK roads but they are soon to make their debut after the Automated Vehicles Act is passed.</p>

<p>When the act is passed, the roads will see a mix of driverless vehicles and human-steered cars.&nbsp;</p>

<h2><strong>White traffic light for self-driving cars</strong></h2>

<p>To ensure that the traffic moves smoothly, the North Carolina State University's engineers have proposed what is called a ‘white light’ at traffic lights that allows self-driving cars to help when there is a traffic flow and allow human drivers to understand what is happening.</p>

<p>Study lead Dr Ali Hajbabaie said that the plan was to get into the computing power of the AVs and understand which vehicles are where.</p>

<p>"The white phase concept incorporates a new traffic signal so that human drivers know what they are supposed to do," Hajbabaie said.</p>

<p>"Red lights will still mean stop. Green lights will still mean go. And white lights will tell human drivers to simply follow the car in front of them," he added.&nbsp;</p>

<p>The paper was published by Dr Hajbabaie and his team in the Journal of&nbsp;Computer-Aided Civil and Infrastructure Engineering.&nbsp;</p>

<p>The team formed a series of computer simulations which helped in visualising how the new traffic light system will work.&nbsp;</p>

The traffic lights on the roads may not appear as they used to any more. For more than a century, the traffic lights have been known to have only three colours - red, amber and green.

The traffic lights on the roads may not appear as they used to any more. For more than a century, the traffic lights have been known to have only three colours - red, amber and green. However, they are now likely to have a fourth colour after scientists suggested that adding another colour will help traffic flow near driverless vehicles. Autonomous vehicles (AV) are a new concept and no completely driverless cars have made it to the road yet. Self-driving taxi firm Waymo is close to finalising what is called SAE4 in California and Arizona and other companies like Tesla are also producing self-driven vehicles. Also Read: A robotic chauffeur! Scientists develop robot which can drive regular cars As of now, the government has not allowed self-driven vehicles on UK roads but they are soon to make their debut after the Automated Vehicles Act is passed. When the act is passed, the roads will see a mix of driverless vehicles and human-steered cars. White traffic light for self-driving cars To ensure that the traffic moves smoothly, the North Carolina State University's engineers have proposed what is called a ‘white light’ at traffic lights that allows self-driving cars to help when there is a traffic flow and allow human drivers to understand what is happening. Study lead Dr Ali Hajbabaie said that the plan was to get into the computing power of the AVs and understand which vehicles are where. "The white phase concept incorporates a new traffic signal so that human drivers know what they are supposed to do," Hajbabaie said. "Red lights will still mean stop. Green lights will still mean go. And white lights will tell human drivers to simply follow the car in front of them," he added. The paper was published by Dr Hajbabaie and his team in the Journal of Computer-Aided Civil and Infrastructure Engineering. The team formed a series of computer simulations which helped in visualising how the new traffic light system will work. Watch: India's luxury car market outpaces overall auto industry by 32% According to the system, the AVs were expected to communicate with each other wirelessly and with the computers which are controlling the traffic signals. At the time when AVs approach the intersection, the computers will activate the new traffic light system. The white light will be an indication that the AVs are coordinating their movements through the intersection and all non-automated vehicles will have to follow the vehicle ahead. Dr Hajbabaie said that the system will improve travel time as well as fuel efficiency and will ensure the safety of everyone on the roads. "If at some point in the future we see almost universal adoption of AVs, our models suggest that delays at intersections would decrease by more than 25%," Dr Hajbabaie said. "More realistically, we will eventually see a lower percentage of wirelessly connected AVs on the road, but there would still be meaningful improvements in traffic time," he added.

Not just red, amber and green, traffic lights will have a new colour. Here's why

<p>In what can be called a double treat for the sky gazers, the night sky was filled with aurora borealis as the Perseid meteor shower started and meteors passed through the sky on August 12 (Monday).</p>

<p>The people came out of their houses and travelled to darker areas to witness the marvellous show in the sky.&nbsp;</p>

<p>In the videos and photos captured, pink and green hues were seen filling the night sky as numerous meteors passed through it. The netizens captured the meteors and the auroras and shared them on platform X.&nbsp;</p>

Here's how netizens reacted to the viral video of the snake and mongooses The viral video of the snake and mongoose was widely circulated on social media and left users amused. “Competitive tussle between IndiGo and Spicejet crew," wrote a user. “No no, it’s 3 Mongoose vs single Cobra. Mongoose follow rules and respect each other. Great respect,” said another user. “Bihar airport is not for beginners," stated a user. Watch: China’s pets to outnumber kids by 2030 “Bridge in the middle of the field, a teacher sleeping in the classroom with children fanning her and now mongoose and snake fighting in the middle of the airport," commented another user. “Their ongoing family issues, and the snake finally decided to settle outside India," said the user, while hinting at Bollywood movie Nagina.

<p>It was earlier believed by scientists that Elapoidea - which is the superfamily of cobras, coral snakes and mambas - first existed in Africa.&nbsp;</p>

<p>However, the hypothesis was proved wrong when scientists discovered the fossil of a file snake in Tanzania&nbsp;which belonged to the Oligocene Epoch (33.9 million to 23 million years ago).&nbsp;</p>

<p>The snake was found to be the oldest relative which belongs to the Elapoidea group as per the fossil record.</p>

<p>In the new research, which was published in the journal&nbsp;Royal Society Open Science, the researchers carried out the fossils and genetic analysis of snakes from other regions to discover that these snakes along with snakes from the superfamily Colubroidea originated in Asia.</p>

<p>A light-driven launch system has been created by Chinese scientists for miniature robots, taking inspiration from squirting cucumbers. This robot can be used in the fields of medicine, agriculture, aerospace and even ballistics.</p>

<p>The soft hydrogel and graphene launcher of the team is able to release energy in just 0.3 milliseconds, which helps the device take off from both wet and dry surfaces and cover a distance that is 643 times its own body height, the South China Morning Post reported.&nbsp;</p>

<p>This technology can help develop miniature&nbsp;medicinal&nbsp;robots as smart-seeding&nbsp;agriculture&nbsp; robots. They can also be used for deep-tissue sampling, and carry the potential of getting used like a soft bullet.</p>

<p>NASA's satellite Neowise, which was being used as a "planetary defence mission" to track asteroids&nbsp;and comets which can prove threatening to Earth, will be crashing into our atmosphere.&nbsp;</p>

<p>In present times, Greenland's 98 per cent area is covered with ice, however, less than a million&nbsp;years ago, it was almost ice-free and was filled with green tundra, as per the new research.&nbsp;&nbsp;</p>

<p>After studying a new fossil discovery from Greenland, the study has stated that the evidence "provides the first direct evidence that the centre — not just the edges — of Greenland's ice sheet melted away in the recent geological past". This was part of the statement&nbsp;released by the University of Vermont.</p>

<p>"Our new data is the strongest confirmation yet that the ice in the centre of the island vanished and was replaced by a tundra ecosystem," said study lead author Paul Bierman, who is a geologist at the University of Vermont, while speaking to Live Science.</p>

<p>For studying the Greenland's past, a sample of ice core which was extracted in 1993 was reexamined by the research team.</p>

<p>In the analysis, the scientists discovered a plethora of fossils, which included fungi, willow and insect body parts. However, the scientist's most spectacular discovery was made in the preserved Arctic poppy seed, which left the team astonished.</p>

<p>"The original plan with the sample was to measure [carbon-dating] isotopes, we didn't know we were going to find fossils," said Bierman.</p>

<p>The scientists also found important evidence in the specimen of rock spike moss<em> </em>(Selaginella rupestris) which is still present in sandy and rocky places.</p>

<p>"They need the things all plants need to grow, and they can't get those on top of an ice sheet," said Halley Mastro, a graduate student at the University of Vermont and co-author of the study, while speaking to Live Science. "They just wouldn't grow," he added.</p>

<h2><strong>Scientists detect loss of ice in Greenland million years ago</strong></h2>

<p>In a 2016 study conducted on the core, it was suggested that the current Greenland ice sheet was almost 1.1 million yeas old.</p>

<p>The scientists also estimated that the loss of the ice at a site, known as GISP2, will mean that 90 per cent of Greenland was nearly ice-free at that time.</p>

<p>Bierman and Mastro reexamined the 1993 core which was kept at the National Science Foundation Ice Core Facility in Colorado for nearly 30 years. "The ice part of the core has been extensively analysed," said Bierman.</p>
