Phys.org / Early-life challenges and experiences shape how boldly bats behave as adults
What makes one bat take risks and venture far from its roost in search of food, while another stays close to familiar, safer areas? A new study from Tel Aviv University's School of Zoology reveals that the environment in ...
Phys.org / Researchers copy viral strategies to get mRNA medicines into cells in one piece
Drugs made of mRNA have the potential to transform medicine—if only they could get into cells in one piece. Now, University of Connecticut researchers have shown that packaging mRNA like a virus could smuggle it into cells ...
Phys.org / Plant hormone therapy could improve global food security by balancing growth with immunity
Plants have an immune system, like people, and when it is triggered by threats like disease or pests, a plant's defenses are activated. But there's a downside to this protective mechanism: the plant's growth is suppressed ...
Phys.org / Reading the enemy: How genome science is reshaping the fight against wheat stem rust
In 2013, farmers in the highlands of Ethiopia began to notice something unsettling: a familiar variety of wheat was failing in an unfamiliar way. Stems weakened, plants collapsed, and fields that had once held firm against ...
Phys.org / EPA criminal sanctions align with a county's wealth, not pollution, study finds
When the federal government brings its toughest environmental enforcement actions against polluters, they tend to be in communities of greater wealth, not the most polluted places. That's the takeaway from a new paper co-authored ...
Phys.org / A new method reveals hidden rules of gene control
Inside every cell, thousands of molecular signals collide, overlap, and compensate, obscuring the true drivers of gene expression. Scientists have now developed a way to silence that cellular noise, revealing transcription ...
Phys.org / Study reveals hidden climate impact of digital industries
Digital technologies are widely viewed as drivers of efficiency, growth, and innovation. However, their contribution to climate change is significantly greater than previously understood. A new study published in the journal ...
Phys.org / How cells manage nitric oxide: Research uncovers dynamic 'gate' that tames powerful signaling molecule
Cornell researchers have uncovered a built-in molecular "gate" that controls the production of the molecule nitric oxide, a crucial signaling molecule throughout biology that in humans helps regulate blood pressure, brain ...
Phys.org / Scientists isolate climatic fingerprints of wildfires and volcanic eruptions
Volcanoes and wildfires can inject millions of tons of gases and aerosol particles into the air, affecting temperatures on a global scale. But picking out the specific impact of individual events against a background of many ...
Phys.org / Big broods, better manners: What a fish study suggests about siblings and social skills
For many animals, siblings are a key component of their social environment during early life. Previous research has shown that the early social environment is important, but it has not yet been clear whether the number of ...
Phys.org / Between flood and drought: The metric that could better explain what happens to water in the age of climate change
A key question in any discussion about climate is "How much rain fell?" But perhaps there is an even more important one. Like any household budget, the global water economy is based on "income," that is, water entering the ...
Phys.org / How the echolocation of bats has shaped their skulls
Bats are some of the most highly specialized mammals to have ever evolved. This includes not only the evolution of active flight, but also their echolocation. This ability requires the bats to produce high frequency noises ...
