Astronomers announce discovery of potential sign of life on Venus
short by Pragya Swastik / on 14 Sep 2020,Monday
A team of astronomers from the US, UK and Japan announced the discovery of rare molecule 'phosphine' in the clouds of Venus as a potential sign of life on the planet. On Earth, this gas is only made industrially or by microbes that thrive in oxygen-free environments. The team estimates that phosphine exists in Venus' clouds at a small concentration.

Aus stinging tree toxins similar to venom found in scorpions: Scientists
short by Nandini Sinha / on 17 Sep 2020,Thursday
The toxins secreted by the Gympie-Gympie stinging tree found in Australia are similar to the venom found in spiders and scorpions, researchers at the University of Queensland said. "The tree is covered in needle-like appendages called trichomes that look like fine hairs, but act like hypodermic needles that inject toxins when they make contact with skin," Associate Professor Vetter said.

Astronomers detect first possible intact planet orbiting a dead star
short by Nandini Sinha / on 17 Sep 2020,Thursday
An international team of astronomers has reported what may be the first intact planet found closely orbiting a white dwarf or a dead star, using NASA's Transiting Exoplanet Survey Satellite (TESS) and retired Spitzer Space Telescope. The exoplanet, known as 'WD 1856 b', is the size of Jupiter. It completes one full orbit every 1.4 days.

A big chunk of ice has broken away from the Arctic's largest remaining ice shelf '79N' or 'Nioghalvfjerdsfjorden' in north-east Greenland, satellite images showed. The broken-off section covers about 110 square kilometres and it has further shattered into many small pieces. "The atmosphere in this region has warmed by about 3℃ since 1980," Dr Jenny Turton told BBC News.

NASA and National Oceanic and Atmospheric Administration experts have announced that the solar minimum occurred in December 2019, marking the start of a new solar cycle. Scientists expect the Sun's activity to ramp up toward the next predicted maximum in July 2025. During solar maximum (left), the Sun is freckled with sunspots and its magnetic field is taut and tangled.

NASA's Curiosity rover has captured plumes of a spinning, columnar vortex of wind known as a 'dust devil' on Mars. It's estimated to be about 16 feet wide and 164 feet tall, NASA wrote sharing a video on Instagram. "This dust devil appears to be passing through small hills just above Curiosity's present location on Mount Sharp," NASA added.

Scientists at the Queen Mary University of London and the Chinese Academy of Science in Nanjing claim they have discovered the world's oldest animal sperm. The sperm was found inside a tiny crustacean trapped in amber around 100 million years ago in Myanmar. They believe the tiny crustaceans had sex just before their entrapment in a blob of tree resin.

Migratory birds are dropping dead in the US, potentially in the "hundreds of thousands", experts have said. Bluebirds, flycatchers, sparrows and warblers are among the species "falling out of the sky" as part of a mass die-off, said Martha Desmond, a professor at New Mexico State University. The wildfires may have contributed to the deaths of the birds, biologists said.

As per a study published in 'One Earth', human activities have converted an area the size of Mexico from virtually intact natural landscapes to heavily modified ones in just 13 years. The loss of 1.9m square kilometres of intact ecosystems would've "profound implications" for Earth's biodiversity, study's authors said. Almost 20% of the earth's surface had deteriorated, the study found.

IIT Kanpur incubated startup, E-Spin Nanotech, which made the 'Swasa' mask PM Modi wore at the Ram Mandir 'bhoomi pujan', has developed a super-activated carbon mask with odourless technology. "Carbon particles hold the odorous particles and adsorb them. When carbon is charged and prepared, its property changes, so it isn't harmful to the body," said the startup.

Netherlands startup makes coffin that gets 'absorbed by nature'
short by Aishwarya / on 14 Sep 2020,Monday
A Netherlands-based student startup claims to have developed a "living coffin" made of mycelium. The coffin, 'The Living Cocoon', helps the body to compost "more efficiently, removes toxic substances and produces richer conditions" for new trees and plants to grow. Practical tests showed that the coffin is actually absorbed by nature "within 30 to 45 days", under normal Dutch conditions.

Astronomers have said there could be a "missing ingredient" in the theories of how dark matter behaves. They found a discrepancy between observations of dark matter concentrations in three clusters of galaxies and theoretical computer simulations of how dark matter should be distributed in clusters. The study involved observations from the Hubble Space Telescope and ESO's VLT in Chile.

All the world's governments have failed to meet any of the 20 Aichi Biodiversity Targets by its deadline in 2020, a UN report said. It claims that six of the 20 targets, that were agreed in 2010, have been partially achieved so far. It also states that $500 billion of government subsidies that are damaging the environment haven't been eliminated.

NASA could approve a mission to Venus that scientists said could help determine whether or not the planet harbours life. It is currently reviewing four proposed missions, two of which would involve robotic probes to Venus. Earlier, scientists had announced the discovery of rare molecule 'phosphine' in the clouds of Venus as a potential sign of life on the planet.

Japanese space agency JAXA announced it's developing a "Super Hi-Vision Camera" capable of filming 8K images in space for its Martian Moons eXploration (MMX) mission. JAXA aims to capture images of Mars and its moons, Phobos and Deimos. The MMX spacecraft is scheduled to be launched in JFY 2024 and will land on Phobos to collect "sand" from its surface.

Researchers have identified the fossilised remains of two previously unknown dinosaurs in China and said their fossils were found in "pristine" conditions. They said the dinosaurs are of the same unknown species and named the species Changmiania liaoningensis, which means "eternal sleeper" in Chinese. Researchers said the dinosaurs appeared to have been buried alive with their eyes closed.

China's practice of converting large swaths of desert into grassland have substantially diminished terrestrially stored water, researchers said. They said the projects were depleting total land water resources at an "alarming rate". Researchers had constructed a continuous record spanning the pre-environmental reclamation period (1982 to 1998) and the post-restoration period (2003 to 2016).

Scientists have found evidence that northern hemisphere of Saturn's moon Enceladus has been resurfaced with ice from its interior. Enceladus shoots out enormous plumes of ice grains and vapour from an ocean that lies under its crust. A global spectral map of Enceladus showed infrared signals that correlate with the geologic activity which is easily seen at the south pole.
