Decompression is a gas

Researchers develop a novel method to reduce decompression sickness risk in divers by introducing hydrogen-metabolizing bacteria into the intestine. This method uses Methanobrevibac smithii to metabolize excess gas, potentially treating digestive issues like bloating and discomfort.

Jet Stream Studied In West African Drought

Researchers at Penn State found a correlation between jet stream strength and precipitation in the Sahel region, which has been experiencing drought since the 1970s. The Tropical Easterly Jet was mostly weaker during dry periods, while the African Easterly Jet showed slightly stronger patterns in very dry years.

Genetic testing and modified diets may save babies born with genetic defect

A recent study published in the New England Journal of Medicine found that genetic testing and dietary modification can save the lives of children born with a defect in fatty acid breakdown. The research team identified 24 infants with liver, heart, or muscular abnormalities and found that dietary treatment was crucial for survival.

Scientists identify molecular source of friction

Physicists at Johns Hopkins University have identified the molecular origins of static friction, resolving a long-standing issue in understanding Amontons' classic laws. The 'gunk in the middle' - hydrocarbon molecules between surfaces - provides an explanation for the linear relationship between force and load.

Advance reported in search for skin cancer treatment

Researchers at the University of Notre Dame have developed a computer model that provides atomic details of the binding interactions between damaged DNA and the repair enzyme DNA photolyase. The model provides new insights into which parts of the enzyme are important for electron transfer, which could lead to the development of an arti...

NIAAA-led study verifies environment-dependent behavioral variation in genetically identical mice

A NIAAA-led study confirms that environmental factors can significantly impact the behavior of genetically identical mice, challenging traditional assumptions about genetic determinism. The research highlights the need for laboratories to replicate tests locally and standardize behavioral tests to minimize environmental influences.

Hi-tech tutoring

A Navy laboratory has successfully demonstrated an AI-powered tutoring system that reduces the number of instructors needed for team training. The system tracks keystroke and eye movement to provide real-time feedback, enabling more effective high-functioning teamwork.
