A study from Karolinska Institutet shows that the number of suicides on Greenland increases sharply during the bright summer months. Too little sleep and chemical imbalance could explain the phenomenon. The study, which was led by Karin Sparring Björkstén at the Department of Neurobiology, Care Sciences and Society, was conducted on Greenland, where variations in sunlight are extreme over the year.

Researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. Los Alamos researchers crack code for binding lignocellulosic biomass LOS ALAMOS, New Mexico, April 22, 2009—Los Alamos National Laboratory researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough.

Cambridge, Mass. April 16, 2009 - A reservoir of briny liquid buried deep beneath an Antarctic glacier supports hardy microbes that have lived in isolation for millions of years, researchers report this week in the journal Science. The discovery of life in a place where cold, darkness, and lack of oxygen would previously have led scientists to believe nothing could survive comes from a team led by researchers at Harvard University and Dartmouth College.

By adjusting nine parameters in a single equation, a computer model can generate patterned shells (right example in each pair above) that closely resemble real mollusk shells. (Alistair Boettiger/UC Berkeley) BERKELEY — University of California, Berkeley, graduate student Alistair Boettiger has amassed a beautiful collection of seashells, but not by combing the beach.

PA84/09 Medical experts at The University of Nottingham have shown that an innovative anti-microbial catheter could vastly improve treatment and the quality of life for many community-based dialysis patients. Results of a study published in the leading journal Biomaterials, have shown that the catheter has the potential to ward off attack from a wider variety of pathogens and protect Continuous Ambulatory Peritoneal Dialysis (CAPD) patients from infections for up to 100 days — around 20 times longer than current catheters.

Engineers at the University of Birmingham, with local company, Ntec, have invented a new casting process that could reduce the energy costs of light-metal foundries. The technology, called CRIMSON, means that foundries need only heat the quantity of metal required to fill a single mould rather than whole batches that use unnecessary energy and create waste.

'Sophia' has just published its second issue, featuring articles on subjects as diverse as deep-space chemistry, fibromyalgia in 'The Princess and the Pea' and the measurement of global happiness, as well as images produced in the course of research. The new issue also includes an article by Professor Donald Gillies (UCL Science & Technology Studies) on how peer-review based assessment exercises such as the RAE 'risk ending the careers of truly talented researchers yet to be recognised by the academic community at large'.

Scientists at Karolinska Institutet have found a way of activating the neuronal reserves in the brains of mice by switching off the signal that inhibits the formation of new nerve cells. The study is presented in the online edition of the scientific. "So far, this is just basic research of no immediate practical significance, but the results are very exciting nonetheless," says Professor Jonas Frisén at the Department of Cell and Molecular Biology, who led the study.

Cambridge, Mass. February 9, 2009 - Genetics may play a surprisingly small role in determining the precise wiring of the mammalian nervous system, according to painstaking mapping of every neuron projecting to a small muscle mice use to move their ears. These first-ever mammalian "connectomes," or complete neural circuit diagrams, reveal that neural wiring can vary widely even in paired tissues on the left and right sides of the same animal.

A chemical, commonly used in the manufacture of rubber products, may cause cancer in workers regularly exposed to it, according to research published today ahead of print in Occupational and Environmental Medicine. The researchers from the University of Birmingham's Institute of Occupational and Environmental Medicine found higher than expected rates of diagnosis and death from a number of cancers, amongst men working at a rubber plant in North Wales.

A group of chemists at the University of Geneva (UNIGE) have just discovered a little-known bond between hydrogen atoms.
