Faced with a common peril, people delay making decisions that might save lives, fail to alert each other to danger and spread misinformation. Those may sound like behaviors associated with the current pandemic, but they actually surfaced in experiments on how social networks function in emergencies. from Top Health News -- ScienceDaily https://ift.tt/3duJFha via IFTTT

Researchers have identified a new genomic region and anxiety-related candidate genes associated with fearfulness in dogs. Findings support their hypothesis that fearfulness and anxiety are hereditary traits in dogs, and there may be shared factors underlying anxiety in both humans and dogs. from Top Health News -- ScienceDaily https://ift.tt/3diw64n via IFTTT

Toxic versions of the protein tau are believed to cause death of neurons of the brain in Alzheimer's disease. A new study shows that the spread of toxic tau in the human brain in elderly individuals may occur via connected neurons. The researchers could see that beta-amyloid facilitates the spread of toxic tau. from Top Health News -- ScienceDaily https://ift.tt/2ApDZqs via IFTTT

In proteins, amino acids are held together by amide bonds. These bonds are long-lived and are robust against changes in temperature, acidity or alkalinity. Certain medicines make use of reactions involving amide bonds, but the bonds are so strong they actually slow down reactions, impeding the effectiveness of the medicines. Researchers devised a way to modify amide bonds with a twist to their chemical structure that speeds up reactions by 14 times. from Top Health News -- ScienceDaily https://ift.tt/2TMwsbQ via IFTTT
