The ophthalmology team of the University Clinic of the University of Navarre has published a new technique to detect diabetic retinopathy. This research has been published in the magazine Investigative Ophthamology and Visual Science. The research is based on the Optical Coherence Tomography (OCT). This test allows measuring the thickness of eye macula without touching the eye and without using contrast injection. The macula is the central part of the retina and is the responsible of the central vis

Subtle alterations of a hormonal stress response system called the HPA axis may play a role in chronic fatigue syndrome, according to a study in the November/December issue of Psychosomatic Medicine.

A smoothly functioning hypothalamus-pituitary-adrenal, or HPA, axis helps the body remain stable under physiological and psychological stress through the actions of three hormones. First, the brain portion called the hypothalamus secretes a hormone that stimulates the pituitary gland to secrete

VLT Images Intergalactic Shock The Universe is a violent place – as astronomers use increasingly sensitive means and methods to study the diverse processes out there, they become aware of the extraordinary forces acting in the space that surrounds us. With larger telescopes and ever-more sophisticated instruments, new information is gained about remote celestial objects and their behaviour. Among the most intriguing ones are the radio galaxies which emit prodiguous amounts of

Reducing the sulphur content of pollutants can have a substantial impact in reducing death from respiratory and cardiovascular diseases, conclude authors of a study in this week’s issue of THE LANCET which describes the effect of a public-health initiative in Hong Kong.

A change in law to restrict sulphur emissions was introduced in Hong Kong in July 1990; all power plants and road vehicles had to use fuel oil with a sulphur content restricted to not more than 0·5% by weight. This intervent

Indiana University information technology experts working with others from the state’s leading educational institutions presented several new tools in high-performance computing, networks and visualization this week to colleagues at the international Supercomputing2002 conference. Among the tools demonstrated were a system that can track the physical location of wireless devices and a powerful mapping application.

Highly acidic drainage from an abandoned sulfide mine in Rowe is slowly cleaning itself over time, and an interdisciplinary research team from the University of Massachusetts Amherst is studying why. The group brings together experts from the fields of microbiology, geology, engineering, and science education, to determine the extent and rate of bioremediation. Researchers say their findings may enable quicker natura
