Phys.org / Crashing insect populations lead to smaller tree swallows that reproduce less
Since the 1970s, the number of insects at Canada's Long Point Bird Observatory has dropped by more than 60%, according to a new study led by the University of Michigan. Because of this, today's birds are smaller and facing ...
Phys.org / Protein-tagging technology maps a hidden communication network between organs
The body's organs are in constant communication. Fat tissue tells the liver when to store or release energy, the immune system signals localized inflammation, and thousands of proteins carry these messages to organs throughout ...
Phys.org / A minimal model for how a cell takes shape from the inside
Researchers at the University of Twente and Utrecht University have packed rigid, rod-shaped particles into soft lipid containers the size of a living cell and watched the container and its contents reshape each other. The ...
Phys.org / Insects exhibit evidence of a daily body clock for humidity
In a novel experiment at the University of Cincinnati, researchers recently isolated kissing bugs, fruit flies, mosquitoes and spider beetles in a climate- and light-controlled environment and found that they responded predictably ...
Phys.org / Primordial halo simulations reveal how cosmic storms shaped the universe's first stars
Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like the Milky Way, no planets, and no heavy elements such as carbon or oxygen. Instead, vast clouds of ...
Phys.org / The Caspian Sea has lost an area nearly the size of Sicily: Human activities are a major reason why
The Caspian Sea, the largest inland body of water on Earth, is shrinking. Not fluctuating, not entering another natural cycle, but shrinking.
Phys.org / Feeding data to AI to speed up drug discovery
Developing new medicines can require thousands of chemistry experiments to identify the right recipe for a safe, effective and ideally affordable drug.
Phys.org / Ordinary enzyme that evolves into 'control switch' reveals tuberculosis weak spot
Researchers at the University of Surrey have identified a protein that acts as a control switch, preventing Mycobacterium tuberculosis from accessing the energy sources it needs to survive. The discovery points to a specific ...
Phys.org / Chaotic polymer vibrations may unlock stronger, flexible thermal insulators
University of Massachusetts Amherst researchers have demonstrated a possible new avenue for developing flame-retardant and generally low-conductivity (low-heat-transfer) plastics that retain the benefits of being strong and ...
Phys.org / How AI-generated cartoons reshaped Taiwan's 2024 protests
In spring 2024, more than 100,000 people protested in Taiwan's streets. On Threads, a parallel fight was underway.
Phys.org / Machine learning helps identify six promising solvents for carbon dioxide electroreduction
Carbon dioxide (CO2) is a primary driver of climate change in Earth's atmosphere. At the State University of New York at Stony Brook (Stony Brook University), Ph.D. researcher Kuldeepsinh Raj, along with principal investigator ...
Phys.org / Heat stress exposure climbed from 16% to 22% worldwide over 50 years, study shows
The number of people exposed to dangerous heat stress worldwide has risen sharply over the past half-century, propelled by climate change, according to a study released Monday as Europe sweltered through a punishing heat ...
