Evidence of elusive high-energy gravitons in quantum Hall systems

Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a phenomenon that emerges when electrons are confined to a ve

Mating strategies shape tropical plants' invasive ability

A recent study from the Center for Ecological Sciences (CES), Indian Institute of Science (IISc), has found strong evidence that a plant's ability to reproduce on its own—through self-fertilization—is one of the key traits that helps it become invasive. The findings are published

Study provides further evidence that aspen patches can mitigate wildfires

Researchers at McGill University have confirmed that aspen play a key role in forest fire prevention and mitigation across Canada. Planting these trees near communities can reduce both the likelihood and severity of fires and limit how far they spread, the researchers said.

Scientists find gas emissions from rocks may have contributed to ancient climate swings, m

An interdisciplinary team from Florida State University's Department of Earth, Ocean, and Atmospheric Science has uncovered new evidence about processes that may have contributed to ancient mass-extinction events, some of the most dramatic ecosystem reorganizations in Earth's his

This Mars rover could finally reveal whether life ever existed on Mars

The hunt for ancient life on Mars just got an important test run. Scientists confirmed that the Rosalind Franklin rover's sophisticated instrument can detect subtle differences in two stable molecules that could preserve evidence of past life for billions of years. But the team a

Ancient fossil may reveal animal kingdom's earliest right-handedness at 550 million years

Scientists have uncovered what may be the earliest evidence of "right-handedness" in the animal kingdom, dating back more than half a billion years. The discovery comes from the fossil record of Spriggina floundersi, an organism from the Ediacaran Period that lived about 550 mill

Hawaii's famous “happy-face” spider has a surprising relative

A newly discovered Happy-Face spider in the Himalayas closely resembles Hawaii's iconic species but evolved independently, according to DNA evidence. Its mysterious smile-like markings, many color forms, and unexpected link to ginger plants have scientists eager to learn how the

Carbon–bismuth bonds reveal that relativity blurs the textbook line between sigma and pi b

Brown University chemists have provided direct evidence that upends the textbook explanation of how triple chemical bonds work in heavy elements. In a study published in Science, the researchers show evidence that when atomic nuclei are sufficiently heavy, the principles describe
