Phys.org / Predator-triggered orange tails may help tadpoles survive by redirecting deadly bites
Bright colors in animals are beautiful but often considered risky because they are more obvious to predators. However, conspicuous colors can also serve defensively, signaling toxicity or even luring predators away from more ...
Phys.org / Wildfire dark brown carbon has strong global warming effects, study finds
A new international study published in Nature Geoscience reveals that dark brown carbon from wildfires exerts a powerful warming effect on the global climate—potentially matching or even exceeding that of black carbon in ...
Phys.org / Megafire kills Joshua trees, but not fungi
When the Dome Fire tore through the Mojave Desert in 2020, it reduced 1 million Eastern Joshua trees to blackened skeletons. Scientists expected the underground ecosystem to be equally devastated. Instead, they found it thriving.
Phys.org / Humans reshape predator-prey rules across food webs, creating a challenging new world for wildlife
The relationship between predators and prey in the wild is underscored by an evolutionary arms race spanning millions of years, but new research has found modern human activity is reshaping the rules.
Phys.org / Forever chemical reaches fish before they even hatch, new study reveals
There is a forever chemical lurking in the world's oceans that could be fundamentally altering the biology of marine life before it even hatches. PFOS, a notorious member of the PFAS family of chemicals, is known for its ...
Phys.org / Green stones buried with Panama's ancient chiefs confirmed as Colombian emeralds
More than 1,000 years ago, Panama elites were buried together with translucent green stones long suspected to be emeralds. However, scientific analysis confirming the suspicion has never been conducted. Now, scientists have ...
Phys.org / Taking dark energy out of the equation: Mathematicians challenge the standard cosmological model of the universe
Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians from the University of ...
Phys.org / Pigeons navigate using magnetic sensors in their livers, say researchers
How pigeons fly hundreds of kilometers and still find their way home has long fascinated people. Now, researchers say a surprising answer may be hidden, not in the brain or eyes of birds, but in the liver.
Phys.org / Bare supercontinent may have tipped ancient Earth into 'Snowball' phase
About a billion years ago, Earth started to come into its own. It was past the awkwardness of its younger years full of growing pains and turmoil: comet strikes and slimy water, including the Great Oxidation Event that flipped ...
Phys.org / How bean plants call on wasps for help when hungry caterpillars attack
Some plants are not the sitting ducks they appear to be when they come under attack. If a hungry caterpillar starts to chomp on the succulent leaves of a common bean plant, a highly sophisticated defense system kicks into ...
Phys.org / The generation of massive Schrödinger cat states using ultracold atoms
Quantum mechanics is a physics framework that describes how matter and energy behave at an extremely small scale, specifically at the scale of atoms and subatomic particles. An effect predicted by the laws of quantum mechanics ...
Phys.org / Quantum pendulum clock overcomes classical accuracy limits and sheds light on quantum to classical transitions
In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism, which converts the ...
