Using a tiny wireless sensor developed at Oak Ridge National Laboratory, doctors will know in minutes instead of hours if an organ is getting adequate blood flow after transplant or reconstructive surgery.

Conventional methods for assessing circulation involve invasive procedures or extensive laboratory testing. In some cases, by the time doctors realize there isn’t adequate blood flow to an organ or tissue, irreversible damage already has occurred.

“Our goal is to offer a te

In the current crisis of global biodiversity loss, the discovery of new species is a welcome addition. But the recent finding that the mountain brushtail possum, an arboreal marsupial mammal of Australian wet forests, is actually made up of two species also poses new conservation challenges.

The new species is proposed in an article in the latest Australian Journal of Zoology (Volume 50, Issue 4), authored by Earthwatch-supported biologist Dr. David Lindenmayer (Australian National Universit

The basque company SK10, which works in the integration of aeronautical structures, has given a significant step forward in its innovation range within compound materials of carbon fibre.

Recently, SK10 has signed with the company EADS-CASA a contract for the development, industrialisation and subsequent mass production of the leading edges of the horizontal stabiliser for the new aircraft Falcon F7X, of the French company DASSAULT.

The development of horizontal stabiliser

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
