Clean Air Act saved 1.5 billion birds, study shows

U.S. pollution regulations meant to protect humans from dirty air are also saving birds. So concludes a new continentwide study published today in The Proceedings of the National Academy of Sciences. Study authors found that improved air quality under a federal program to reduce ozone polluti

Supersized wind turbines generate clean energy—and surprising physics

Twenty years ago, wind energy was mostly a niche industry that contributed less than 1% to the total electricity demand in the United States. Wind has since emerged as a serious contender in the race to develop clean, renewable energy sources that can sustain the grid and meet the ever-rising glob

Lunar Mission Is Latest Milestone in China's Space Ambitions

China´s latest trip to the moon is another milestone in the Asian powerhouse´s slow but steady ascent to the stars. China became the third country to put a person into orbit 17 years ago and the first to land on the far side of the moon in 2019. Future ambitions include a permanent sp

China Sets Launch Window for Mission to Moon

China plans to launch an unmanned spacecraft to the moon between 4 am and 5 am Beijing time on Tuesday (2000-2100 GMT on Monday), the official Xinhua news agency said, citing information from the country’s National Space Administration. Chang’e 5 is the country's most ambitious lunar

Drying Habitat Makes Australia's Platypus Vulnerable, Scientists Say

Australian scientists pushed on Monday to list the platypus as a vulnerable species after a report showed the habitat of the semi-aquatic native mammal had shrunk more than a fifth in the last 30 years. Severe drought brought by climate change, land clearing for farming and dam-building are to bl

British Pianist's Velvety Tones Soothe Thailand's Hungry Monkeys

While on tour in central Thailand, British musician Paul Barton has been mobbed by unruly audiences that tug his hair, steal his music and climb over his piano. Barton is a rock star to hundreds of hungry wild monkeys that he hopes his music can calm, at a time when Thailand's coronavirus-induced

‘Dog kennel’ satellite launched into space to measure rising sea levels

  A satellite shaped like a dog kennel launched into space on Saturday with the goal of measuring global sea levels. A SpaceX Falcon 9 rocket carried the satellite, called Sentinel-6 Michael Freilich, into space from an air force base in California. The spacecraft is one of the most ad

Plant evolves to become less visible to humans

A plant used in traditional Chinese medicine has evolved to become less visible to humans, new research shows.   Scientists found that Fritillaria delavayi plants, which live on rocky slopes of China's Hengduan mountains, match their backgrounds most closely in areas where they are heav

New Chinese submersible reaches Earth's deepest ocean trench

China livestreamed footage of its new manned submersible parked at the bottom of the Mariana Trench on Friday, part of a historic mission into the deepest underwater valley on the planet.   The "Fendouzhe", or "Striver", descended more than 10,000 metres (about 33,000 feet) into the sub

Searching for axion dark matter conversion signals in the magnetic fields around neutron stars

According to theoretical predictions, axion dark matter could be converted into radio frequency electromagnetic radiation when it approaches the strong magnetic fields that surround neutron stars. This radio signature, which would be characterized by an ultranarrow spectral peak at a frequency tha

Astronomers discover new 'fossil galaxy' buried deep within the Milky Way

Scientists working with data from the Sloan Digital Sky Surveys' Apache Point Observatory Galactic Evolution Experiment (APOGEE) have discovered a "fossil galaxy" hidden in the depths of our own Milky Way.   This result, published today in Monthly Notices of the Royal Astronomical

Some Amazon rainforest regions more resistant to climate change than previously thought

Forests can help mitigate climate change, by taking in carbon dioxide during photosynthesis and storing it in their biomass (tree trunks, roots, etc.). In fact, forests currently take in around 25-30% of our human-generated carbon dioxide (CO2) emissions. Certain rainforest regions, such as the Am

Researchers prove water has multiple liquid states

Water is a ubiquitous liquid with many highly unique properties. The way it responds to changes in pressure and temperature can be completely different from other liquids, and these properties are essential to many practical applications and particularly to life as we know it. What causes these an

Can animals use iridescent colors to communicate?

A new paper from the University of Melbourne reveals how animals use beautiful but unreliable iridescent colors as communication signals. Special adaptations enable animals to control how these shifting colors appear so that they can convey reliable information. The new work now published in 

Going beyond the anti-laser may enable long-range wireless power transfer

Ever since Nikola Tesla spewed electricity in all directions with his coil back in 1891, scientists have been thinking up ways to send electrical power through the air. The dream is to charge your phone or laptop, or maybe even a healthcare device such as a pacemaker, without the need for wires an

Five new dwarf galaxies detected around M63

Using an amateur 0.14-m aperture telescope, astronomers have observed a nearby spiral galaxy known as M63 (or NGC 5055). The observations identified the presence of five faint dwarf galaxies around M63 and allowed the researchers to determine their basic parameters. The finding is reported in a pa

Researchers describe fundamental processes behind movement of magnetic particles

The motion of magnetic particles as they pass through a magnetic field is called magnetophoresis. Until now, not much was known about the factors influencing these particles and their movement. Now, researchers from the University of Illinois Chicago describe several fundamental processes associat

Kakapo Wins New Zealand's Bird of the Year

Kakapo, a critically endangered large parrot that can't fly and hides during the day is back in the limelight having been named New Zealand's bird of the year for an unprecedented second time, The Guardian reported. The green and fawn kakapo– the world's heaviest, longest-living parrot &nda
