Phys.org / Research shines light on 'double-yielding' behavior in soft materials
For decades, scientists have observed, but been unable to explain, a phenomenon seen in some soft materials: When force is applied, these materials exhibit not one, but two spikes in energy dissipation, known as overshoots. ...
Phys.org / Illegal cannabis cultivation leaves lasting chemical footprint on California's public lands
A study published in Science of the Total Environment sheds light on the persistent chemical contaminants left behind at illegal cannabis cultivation sites, also known as "trespass grows," on California's federally managed ...
Phys.org / Protein sidekick exhibits dual roles in stress granule assembly and disassembly
Stress granules are droplet-like protein hubs that temporarily shield fragile RNA from cellular stresses such as toxins. VCP is a protein essential for breaking up stress granules and has been linked to neurodegenerative ...
Phys.org / Women portrayed as younger than men online, and AI amplifies the bias
U.S. Census data shows no systematic age differences between men and women in the workforce over the past decade. And globally, women on average live about five years longer than men. But that's not what you'll see if you ...
Phys.org / Tree swallows thrive despite pollution from forever chemicals
A new paper in Environmental Toxicology and Chemistry indicates high levels of exposure to "forever chemicals" in the environments of many tree swallow bird groups in the United States. Despite this, chemical exposure did ...
Phys.org / Orthopedic implants aim to last longer with liquid metal-based nanomaterials
A pioneering liquid metal combination is shaping up as a potential secret weapon in the global fight against antimicrobial resistance, and promises to outlast existing implant materials.
Phys.org / Deforestation can cause eight-fold increase in flood event risk
New research, based on forest fires in Australia, proves there is a significantly higher risk of large-scale flooding when major deforestation has occurred in catchment areas. The chance of large-scale flooding in a specific ...
Phys.org / Composing crews for Mars missions: Team diversity may foster resilience
Simulation results highlight how team composition shapes stress, health, performance, and cohesion in long-duration space missions, according to a study published October 8, 2025, in the open-access journal PLOS One by Iser ...
Phys.org / Carbon monitoring: Modeling effort helps to quickly and accurately estimate forest biomass
A tree can sequester quite a bit of carbon, and forests can sequester and store quite a bit more, but knowing exactly how much is important for many reasons, from planning and management decisions to assessing a forest's ...
Phys.org / How different bird species forage together in the Antarctic
It's a scene fit for a nature documentary: In the frigid ocean surrounding Antarctica, the water boils over as seabirds dive from above and marine animals like seals and whales rise from the depths to all feast on krill.
Phys.org / Direct signal analysis helps solve 50-year-old problem in molecular fluorescence analysis
Last year, we celebrated 50 years since the first papers on fluorescence correlation spectroscopy (FCS) were published. It wasn't a wild celebration with masses on the streets, nor was it widely celebrated in universities, ...
Phys.org / Enhancing the industrial relevance of alcohol dehydrogenase enzymes by exploiting their 'hidden reactivity'
Amides and thioesters are ubiquitous compounds in chemistry, used for the production of medicines, natural products, and advanced materials. Traditionally, their synthesis is a messy business, involving wasteful reagents, ...
