 A new study of the brain's master circadian clock -- known as the suprachiasmatic nucleus, or SCN -- reveals that a key pattern of rhythmic neural activity begins to decline by middle age. The study, whose senior author is UCLA Chancellor Gene Block, may have implications for the large number of older people who have difficulty sleeping and adjusting to time changes.

 Artificial intelligence has been the inspiration for countless books and movies, as well as the aspiration of countless scientists and engineers. Researchers at the California Institute of Technology (Caltech) have now taken a major step toward creating artificial intelligence -- not in a robot or a silicon chip, but in a test tube.

 Researchers at Universitat Autònoma de Barcelona (UAB) have developed an electronic tongue which can identify different types of cava wines, thanks to a combination of sensor systems and advanced mathematical procedures. The device automatically produces classifications similar to those of a sommelier and can be useful in detecting defects during the elaboration of these wines.

How do cells know where to position themselves and where to accumulate in order to carry out their functions correctly within each organ? Researchers with the Colorectal Cancer Lab at IRB Barcelona have revealed the molecular mechanisms responsible for organizing the intestinal epithelium into distinct compartments.

Many substances and nutrients are exchanged across the cell membrane. Scientists at Ecole Polytechnique Fédérale de Lausanne in Switzerland have developed a method to observe these exchanges, by taking a highly accurate count of the number of proteins found there.
Their research has just been published in the online journal PLoS ONE.

Researchers in Ottawa report new hope for the treatment of infants born with serious genetic disorder.
Over 1000 children in Canada are affected with Spinal Muscular Atrophy (SMA), a genetic disorder that causes muscle weakness and loss of motor control. In its most severe form survival of children with SMA beyond 5 years is rare.

 In order to create proteins, the protein-coding gene must be transcribed into RNA and in the so-called splicing process shortened to the correct template. Scientists at the Helmholtz Zentrum München and Munich's Technical University have now discovered how the U2AF protein enables this process.

 A simple cut to the skin unleashes a complex cascade of chemistry to stem the flow of blood. Now, scientists at Washington University School of Medicine in St. Louis have used evolutionary clues to reveal how a key clotting protein assembles. The finding sheds new light on common bleeding disorders.
