An alien world believed to be the first-known planet to consist largely of diamond now appears less likely to be of such precious nature, according to a new analysis led by UA graduate student Johanna Teske. The new research will be published in the Astrophysical Journal. Fuente :...

Starting with a discovery in zebrafish in 2007, Harvard Stem Cell Institute researchers have published initial results of a Phase Ib human clinical trial of a therapeutic that has the potential to improve the success of blood stem cell transplantation. This marks the first time, just nine short...

To gauge whether suspects involved in accidents or routine traffic stops have been driving drunk, police officers pair field sobriety tests with breathalyzers, which signal the presence of alcohol in the breath. Most breathalyzers are expensive and unable to test for precise concentrations of...

A team of researchers led by UA assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds that contain nitrogen-vacancy centers. The unexpected and attractive properties of these "flawed" diamonds put them in the spotlight as promising...

Cold seeps are the basis for a surprising diversity in the desert-like deep sea. Off the coast of Costa Rica, an international team of scientists documented lithodid crabs of the genus Paralomis sp. grazing bacterial mats at a methane seep. The analysis show that not only sessile organisms benefit...

Researchers have developed a new approach with applications in materials development for energy capture and storage and for optoelectronic materials. The research shows that peptide precursor materials can be aligned and oriented during their assembly into polypeptides using tailored flows in...

Expanding programs like Meals on Wheels, because they help some Medicaid-receiving seniors stay out of nursing homes, would save 26 of 48 states money, in addition to allowing more seniors to stay in their own homes, according to a new study. Fuente :...
