| Robots use fear to fight invasive fish Posted: 16 Dec 2021 11:59 AM PST The invasive mosquitofish (Gambusia holbrooki) chews off the tails of freshwater fishes and tadpoles, leaving the native animals to perish while dining on other fishes' and amphibians' eggs. Researchers engineered a robot to scare mosquitofish away, revealing how fear alters its behavior, physiology, fertility -- and may help turn the tide against invasive species. |
| Secret embraces of stars revealed by Alma Posted: 16 Dec 2021 11:59 AM PST Unlike our Sun, most stars live with a companion. Sometimes, two come so close that one engulfs the other -- with far-reaching consequences. When astronomers used the telescope Alma to study 15 unusual stars, they were surprised to find that they all recently underwent this phase. The discovery promises new insight on the sky's most dramatic phenomena -- and on life, death and rebirth among the stars. |
| Energy-saving glass 'self-adapts' to heating and cooling demand Posted: 16 Dec 2021 11:50 AM PST Scientists have developed a material that, when coated on a glass window panel, can effectively self-adapt to heat or cool rooms across different climate zones in the world, helping to cut energy usage. |
| How crowds can make bridges wobble and sway Posted: 15 Dec 2021 05:41 PM PST Researchers have uncovered a surprising new explanation for why pedestrian bridges can suddenly start to wobble and sway: too many people crossing at once and simply trying not to fall over. |
| Winter is coming: Researchers uncover the surprising cause of the little ice age Posted: 15 Dec 2021 11:20 AM PST New research provides a novel answer to one of the persistent questions in historical climatology, environmental history and the earth sciences: what caused the Little Ice Age? The answer, we now know, is a paradox: warming. |
