Mystery of cot death may be explained

A failure to 'gasp' has long been proposed as the basis for sudden infant death syndrome, or cot death. A team at the University of Bristol has discovered a subset of cells in the brain that have the ability to self-generate nervous impulses, which appear essential for gasping. These cells have been termed 'pacemakers'.

Researchers capture the electrical activity of a single sperm cell

Researchers at Children's Hospital Boston and the Howard Hughes Medical Institute have, for the first time, captured the electrical activity of a single sperm cell. The technically difficult maneuver, reported in Nature, allows the first measurement of the currents that flow across the sperm's outer membrane.

Tetracaine mouthwash helps with pain linked to head and neck cancer

Doctors in Italy are studying whether a new type of mouthwash will help alleviate pain for patients suffering from head and neck cancer who were treated with radiation therapy, according to a study published in the International Journal of Radiation Oncology-Biology-Physics

Abraham Lincoln may have suffered from movement disorder

Researchers at Johns Hopkins and the University of Minnesota have discovered a gene mutation in the descendants of Abraham Lincoln's grandparents that suggests the Civil War president himself might have also suffered from a disease that destroys nerve cells in the cerebellum-- the part of the brain that controls movement.

Intracellular observation of RNA metabolism will help identify disease-associated RNAs

For the first time, researchers can now peer inside intact cells to not only identify RNA-binding proteins, but also observe-in real-time-the intricate activities of these special molecules that make them key players in managing some of the cell's most basic functions.

HIV revealed in 3D

HIV, the virus which leads to AIDS and which affects 40 million people across the world, has been seen in 3D detail for the first time by Oxford scientists and their colleagues in Heidelberg and Munich.

Inducing labor shows some benefits in cases of premature water break

A new review of recent studies suggests there are some benefits to inducing labor in women whose water breaks at the point of full-term pregnancy but before the start of labor.

Self-exploding microcapsules for smart drug delivery

Belgian chemists have developed "self-exploding" microcapsules that could one day precisely release drugs and vaccines inside the human body weeks or even months after injection.

Molecular finding will help better understand measles and mumps

A team of Northwestern University researchers has solved the structure of a molecule that controls the ability of viruses of the paramyxovirus family, including the viruses that cause measles, mumps, and many human respiratory diseases, to fuse with and infect human cells.

Molecular link between high fat diets and type 2 diabetes established

Howard Hughes Medical Institute researchers have discovered a molecular link between a high-fat, Western-style diet, and the onset of type 2 diabetes. In studies in mice, the scientists showed that a high-fat diet disrupts insulin production, resulting in the classic signs of type 2 diabetes.
