Playing video games offers learning across life span, say studies
Certain types of video games can have beneficial effects, improving gamers' dexterity as well as their ability to problem-solve -- attributes that have proven useful not only to students but to surgeons, according to research discussed Sunday at the Annual Convention of the American Psychological Association.

Analysis of Lake Washington microbes shows the power of metagenomic approaches
Today's powerful sequencing machines can rapidly read the genomes of entire communities of microbes, but the challenge is to extract meaningful information from the jumbled reams of data.

Synthetic moleculues could add spice to fight against cancer
Seeking to improve on nature, scientists used a spice-based compound as a starting point and developed synthetic molecules that, in lab settings, are able to kill cancer cells and stop the cells from spreading.

Improved technique determines structure in membrane proteins
By combining custom-built spectrometers, novel probe designs and faster pulse sequences, a team led by Illinois chemistry professor Chad Rienstra has developed unique capabilities for probing protein chemistry and structure through the use of solid-state nuclear magnetic resonance spectroscopy.

New 52-city report examines use of wastewater in urban agriculture
As developing countries confront the first global food crisis since the 1970s as well as unprecedented water scarcity, a new 53-city survey conducted by the International Water Management Institute indicates that most of those studied (80 percent) are using untreated or partially treated wastewater for agriculture.

Chemists move closer toward developing safer, fully-synthetic form of heparin
Chemists are reporting a major advance toward developing a safer, fully-synthetic version of heparin, the widely used blood thinner now produced from pig intestines.

APA resolves to play leading role in improving treatment for gender-variant people
The American Psychological Association urged psychologists today to take a leading role in ending discrimination based on gender identity, calling upon the profession to provide
