Stress-induced genomic instability facilitates rapid cellular adaption in yeast
Cells trying to keep pace with constantly changing environmental conditions need to strike a fine balance between maintaining their genomic integrity and allowing enough genetic flexibility to adapt to inhospitable conditions. ...
Improving crop yields in a world of extreme weather events
Farmers in the United States witnessed record-breaking extremes in temperature and drought during the last two summers, causing worldwide increases in the costs of food, feed and fiber. Indeed, many climate ...
A hidden genetic code: Researchers identify key differences in seemingly synonymous parts of the structure
Harvard scientists say they've solved a mystery that's nearly as old as science's understanding of the genetic code.
Birth during a drought correlated with poor health in baboons
The saying "what doesn't kill you makes you stronger" may not hold up to scientific scrutiny.
Bent out of shape: Stressed bacteria accumulate misfolded proteins and stop growing
(Phys.org) —Whether a man, a mouse or a microbe, stress is bad for you. Experiments in bacteria by molecular biologists in Peter Chien's lab at the University of Massachusetts Amherst, with others at MIT, ...
Early warning signs of population collapse
Many factors—including climate change, overfishing or loss of food supply—can push a wild animal population to the brink of collapse. Ecologists have long sought ways to measure the risk of such a collapse, ...
Study shows rising ocean acidification likely to cause shrimp to taste bad
Key genetic mechanism in plant hormone signaling may help protect crops from stressors
Scientists at the Salk Institute for Biological Studies have discovered a key genetic switch by which plants control their response to ethylene gas, a natural plant hormone best known for its ability to ripen ...
Zombies offer key to understanding how crowds evacuate
Zombies might not be the most obvious candidates to use when researching how crowds evacuate buildings, but they have proved a key factor in a new study into crowd behaviour.
Recent droughts could be new normal, may lead to massive tree death, study suggests
Evidence uncovered by a University of Tennessee, Knoxville, geography professor suggests recent droughts could be the new normal. This is especially bad news for our nation's forests.
Researchers measure cavitation noise in trees
Researchers find little correlation between microbial gene expression and environmental conditions in the laboratory
A new study challenges the orthodoxy of microbiology that in response to environmental changes, bacterial genes will boost production of needed proteins and decrease production of those that aren't. Researchers ...
Researchers discover a compound that controls Listeria
In a year when cantaloupe tainted with the bacterium Listeria monocytogenes killed 30 people, the discovery of a compound that controls this deadly bacteria -- and possibly others -- is great news.
Predators have outsized influence over habitats, research says
A grasshopper's change in diet to high-energy carbohydrates while being hunted by spiders may affect the way soil releases carbon dioxide into the atmosphere, according to Yale and Hebrew University researchers ...
