Foldit Gamers Strike Again - Creative Power Of Foldit Gamers Unraveled

in technology, biology

Researchers now reveal the creative power of Foldit players' strategies and compare them to the best-known scientist-developed methods. This report follows a recent paper on solving the crystal structure of a monomeric retroviral protease by protein folding game players.   

Why do neurons die in Parkinson's disease?

in medicine, biology

A new study shows that genetic mutations causing a hereditary form of Parkinson's disease cause a cellular organalle, mitochondria, to run amok inside the cell, leaving the cell without a brake to stop them.

How Headache Tree Causes Cluster Headache and Migraine

in medicine, biology

Researchers have now identified the mechanism by which the plant California laurel, also known as headache tree, causes headache and migraine. They discovered that headache is caused when a bioactive compound released from the leaves of this plant triggers a cascade of chemical events in trigeminal nerves around head arteries. 

Metabolic protein plays unexpected role in tumor cell formation and growth

in medicine, biology

New findingsindings point to possible personalized brain tumor therapy with Src inhibitors. The embryonic enzyme pyruvate kinase M2 (PKM2) has a well-established role in metabolism and is highly expressed in human cancers.

Atomic Force Microscopy Solves Cell Wall Mechanics Problem

in biology

In one of the first applications of atomic force microscopy to the study of tissue and cell mechanics in development, a team of scientists from France and Switzerland linked the changes in cell wall mechanics and chemical modifications of the cell wall structure to organ emergence and patterning.

Brains Come Wired for Cooperation

in medicine, biology

The brain is built for cooperative activity, whether it be dancing on a reality television show, constructing a skyscraper or  working in an office, according to a study led by Johns Hopkins behavioral neuroscientist Eric Fortune and published in the November 4 issue of the journal Science.

Hippocampus plays bigger memory role than previously thought

in biology

Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms.
