Gender gaps remain for many women scientists, study finds
As more women have entered the biomedical field, they're getting a bigger share of research grants, and the gender gap in research funding appears to be narrowing, but the gains have been uneven......»»
Exploring extremes in the search for life on Mars
People might assume the search for life on Mars ended when NASA's first rovers sent back images of the planet's barren, inhospitable surface. However, as scientists broaden their understanding of the extreme conditions in which life can flourish here.....»»
Record low Antarctic sea ice "extremely unlikely" without climate change, says scientists
Scientists at the British Antarctic Survey (BAS) have found that the record-low levels of sea ice around Antarctica in 2023 were extremely unlikely to happen without the influence of climate change. This low was a one-in-a-2000-year event without cli.....»»

Using vague language about scientific facts misleads readers
Using subjective phrasing like "scientists believe" makes facts seem like opinions. Enlarge Anyone can do a simple experiment. Navigate to a search engine that offers suggested completions for what you type, and start t.....»»
Study reveals how a sugar-sensing protein acts as a "machine" to switch plant growth—and oil production—on and off
Proteins are molecular machines, with flexible pieces and moving parts. Understanding how these parts move helps scientists unravel the function a protein plays in living things—and potentially how to change its effects. Biochemists at the U.S. Dep.....»»
Scientists develop new geochemical "fingerprint" to trace contaminants in fertilizer
An international team of scientists has uncovered toxic metals in mineral phosphate fertilizers worldwide by using a new tool to identify the spread and impact of such contaminants on soil, water resources, and food supply......»»

Scientists demonstrate the survival of quantum coherence in a chemical reaction involving ultracold molecules
If you zoom in on a chemical reaction to the quantum level, you'll notice that particles behave like waves that can ripple and collide. Scientists have long sought to understand quantum coherence, the ability of particles to maintain phase relationsh.....»»
Sea otter study finds tool use allows access to larger prey, reduces tooth damage
Sea otters are one of the few animals that use tools to access their food, and a new study has found that individual sea otters that use tools—most of whom are female—are able to eat larger prey and reduce tooth damage when their preferred prey b.....»»
Proteomic analysis reveals how phosphite contributes to the fight against chemically resistant dieback
Having previously confirmed dieback is resistant to chemical control on crops such as avocados, stone fruits and pines, Curtin University researchers have gained new insights into how phosphite works against the fungus-like disease, in a potential br.....»»
Researchers achieve ultra-high-Q free space coupling to microtoroid resonators
Scientists from the University of Arizona have achieved far-field coupling of light to ultra-high quality factor microtoroids using a single objective lens. This could provide the foundation for a fully on-chip multiplexed microtoroid sensing platfor.....»»
