The elephantnose fish explores objects in its surroundings by using its eyes or its electrical sense - sometimes both together. Zoologists at the University of Bonn and a colleague from Oxford have now found out how complex the processing of these sensory impressions is. With its tiny brain, the fish achieves performance comparable to that of humans or mammals. The advance results have been published online in the "Proceedings of the National Academy of Sciences of the United States of America" (PNAS). The print issue will appear soon.

International researchers centered at Nagoya University use a highly sensitive technique to identify significantly more DNA sequence repeats in patients with schizophrenia than in control individuals, and outline a possible link between genome instability and disease.

Washington, DC - June 24, 2016 - Bacteria that have the potential to abet breast cancer are present in the breasts of cancer patients, while beneficial bacteria are more abundant in healthy breasts, where they may actually be protecting women from cancer, according to Gregor Reid, PhD, and his collaborators. These findings may lead ultimately to the use of probiotics to protect women against breast cancer. The research is published in the ahead of print June 24 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Roughly 90 percent of the biggest black holes are dormant, meaning that they are not actively devouring matter and therefore not giving off any light or other radiation.

Yet dormant is not dead, so when a star wanders too close, the ensuing feeding frenzy - a tidal disruption event - sets off a spectacular fireworks show. 

Rice farming is a far older practice than we knew. The oldest evidence of domesticated rice in China has now been pushed back to 9,000 years ago, thanks to a team of archaeologists.

Depression is different for African-Americans than Caucasian-Americans or Latin-Americans, and   the Diagnostic and Statistical Manual of Mental Disorders (DSM-V), the primary source of diagnostic information for clinicians, psychiatric drug regulation agencies, health insurance companies, the legal system, is getting it wrong, according to Sirry Alang, assistant professor of sociology and anthropology at Lehigh University.
