Meeting the demand for more data storage in smaller volumes means using materials made up of ever-smaller magnets, or nanomagnets. One promising material for a potential new generation of recording media is an alloy of iron and platinum with an ordered crystal structure. Researchers led by Professor Kai Liu and graduate student Dustin Gilbert at the University of California, Davis, have now found a convenient way to make these alloys and tailor their properties.

Youth bullying because of perceived sexual orientation widespread and damaging

Bullying because of perceived sexual orientation is prevalent among school-aged youths, according to a study led by Donald Patrick, professor of health services at the UW School of Public Health. The study was published online May 16 in the American Journal of Public Health.

SUMO wrestling cells reveal new protective mechanism target for stroke

Scientists investigating the interaction of a group of proteins in the brain responsible for protecting nerve cells from damage have identified a new target that could increase cell survival.

The discovery, made by researchers from the University’s School of Biochemistry and published in the EMBO journal with additional comment in Nature Reviews, could eventually lead to new therapies for stroke and other brain diseases.

New study reveals patterns of dinosaur brain development

A new study conducted at the University of Bristol and published online today in the Journal of Evolutionary Biology sheds light on how the brain and inner ear developed in dinosaurs.

Stephan Lautenschlager from Bristol’s School of Earth Sciences, together with Tom Hübner from the Niedersächsische Landesmuseum in Hannover, Germany, picked the brains of 150 million year old dinosaurs.

First Long-Term Study Reveals Link Between Childhood ADHD and Obesity

Posted: 20 May 2013 08:38 AM PDT

A new study conducted by researchers at the Child Study Center at NYU Langone Medical Center found men diagnosed as children with attention-deficit/hyperactivity disorder (ADHD) were twice as likely to be obese in a 33-year follow-up study compared to men who were not diagnosed with the condition. The study appears in the May 20 online edition of Pediatrics.
