Toxins force construction of ‘roads to nowhere’
Toxins released by a type of bacteria that cause diarrheal disease hijack cell processes and force important proteins to assemble into ‘roads to nowhere,’ redirecting the proteins away from other jobs that are key to proper cell function, a new study h…
Artificial neural networks learn better when they spend time not learning at all
Researchers discuss how mimicking sleep patterns of the human brain in artificial neural networks may help mitigate the threat of catastrophic forgetting in the latter, boosting their utility across a spectrum of research interests.
Rapid fluctuations in oxygen levels coincided with Earth’s first mass extinction
Rapid changes in marine oxygen levels may have played a significant role in driving Earth’s first mass extinction, according to a new study.
New study identifies connection between diabetes medications, multiple sclerosis
A study has found that anti-hyperglycemic medications used to treat Type 2 diabetes resulted in an increased risk of multiple sclerosis for people older than 45, particularly among women.
Looking at oxygen storage dynamics in three-way catalysts
A new isotope labeling and catalyst quenching-based direct visualization technique was developed to explain the oxygen storage and release process in three-way catalysts (TWCs) used in vehicular exhaust treatment systems.
