Astronomers have discovered a relic from the early universe — a star that may have been among the second generation of stars to form after the Big Bang. Located in the dwarf galaxy Sculptor some 290,000 light-years away, the star has a remarkably similar chemical make-up to the Milky Way’s oldest stars. Its presence supports [...]

A research team that conducted the gene therapy trial for an inherited blindness reports that a study in animals has shown that a second injection of genes into the opposite, previously untreated eye is safe and effective, with no signs of interference from unwanted immune reactions following the earlier injection. These new findings suggest that [...]
An early test for fungal infections that measures how a patient’s genes are responding could save the lives of some very sick patients. Researchers have devised an early gene-expression test for the fungal pathogen Candida that worked in mice.

Scientists shed new light on the chaotic motion of a solid body moving through a fluid. They claim to have discovered two basic mechanisms that lead to chaotic motion of the body as it interacts with its vortex wake. The work may lead to better understanding and control of real body-vortex interactions.

A recent report confirmed that 3.5 to 5.3 million people (1-2 percent of the US population) have chronic hepatitis B virus or hepatitis C virus infections. Despite efforts by federal, state and local government agencies to control and prevent these diseases, they remain a serious public health concern.
