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

Tethered Robotic Sub Helps Engineers Refine Computerized Navigation, Control Systems

In a new indoor tank filled with almost 43,000 gallons of water, Johns Hopkins engineers are developing and testing computer control systems to serve as the “brains” for some of the world’s leading deep sea robotic exploration vehicles. To promote advances in underwater robotics, the Whiting School of Engineering recently constructed the circular hydrodynamics tank, 14 feet deep and 25 feet in diamet
