| Posted: 23 Dec 2021 11:30 AM PST The two-meter skull of an enormous new ichthyosaur species, Earth's first known giant creature, reveals how both the extinct marine reptiles and modern whales became giants. |
| These fish work together by the hundreds of thousands to make waves Posted: 22 Dec 2021 12:31 PM PST In the sports arena, spectators sometimes create a spectacle known as a wave, as successive groups stand up in unison to yell with arms in the air. Now, researchers have shown that small freshwater fish known as sulphur mollies do a similar thing, and for life or death reasons. The collective wave action produced by hundreds of thousands of fish working together helps to protect them from predatory birds. |
| Ancient DNA reveals the world’s oldest family tree Posted: 22 Dec 2021 12:31 PM PST Analysis of ancient DNA from one of the best-preserved Neolithic tombs in Britain has revealed that most of the people buried there were from five continuous generations of a single extended family. By analysing DNA extracted from the bones and teeth of 35 individuals entombed at Hazleton North long cairn in the Cotswolds-Severn region, the research team was able to detect that 27 of them were close biological relatives. The group lived approximately 5700 years ago. |
| Astronomers uncover largest group of rogue planets yet Posted: 22 Dec 2021 12:31 PM PST Rogue planets are elusive cosmic objects that have masses comparable to those of the planets in our Solar System but do not orbit a star, instead roaming freely on their own. Not many were known until now, but a team of astronomers, using data from several European Southern Observatory (ESO) telescopes and other facilities, have just discovered at least 70 new rogue planets in our galaxy. This is the largest group of rogue planets ever discovered, an important step towards understanding the origins and features of these mysterious galactic nomads. |
| Astronomers capture black hole eruption spanning 16 times the full Moon in the sky Posted: 22 Dec 2021 12:30 PM PST Astronomers have produced the most comprehensive image of radio emission from the nearest actively feeding supermassive black hole to Earth. The emission is powered by a central black hole in the galaxy Centaurus A, about 12 million light years away. When viewed from Earth, the eruption from Centaurus A now extends eight degrees across the sky -- the length of 16 full Moons laid side by side. |
| Humble lizards offer surprising approach to engineering artificial lungs Posted: 22 Dec 2021 12:29 PM PST A new study shows how the brown anole lizard solves one of nature's most complex problems -- breathing -- with ultimate simplicity. Whereas human lungs develop over months and years into baroque tree-like structures, the anole lung develops in just a few days into crude lobes covered with bulbous protuberances. These gourd-like structures, while far less refined, allow the lizard to exchange oxygen for waste gases just as human lungs do. And because they grow quickly by leveraging simple mechanical processes, anole lungs provide new inspiration for engineers designing advanced biotechnologies. |
| Sensor based on quantum physics could detect SARS-CoV-2 virus Posted: 21 Dec 2021 10:34 AM PST Researchers found it's possible to design a sensor, based on quantum physics, that could detect the SARS-CoV-2 virus. The approach may offer faster, cheaper, and more accurate detection of Covid-19, including of new variants. |
