The Glory of a Nearby Star
Optical Light from a Hot Stellar Corona Detected with the VLT The solar corona is a beautiful sight during total solar eclipses. It is the uppermost region of the extended solar atmosphere and consists of a very hot (over 1 million degrees), tenuous plasma of highly ionised elements that emit strong X-ray radiation. There is also a much weaker... view more... (2001-07-31)

Geologists reveal secrets behind supervolcano eruption
Researchers at Rensselaer Polytechnic Institute have discovered what likely triggered the eruption of a "supervolcano" that coated much of the western half of the United States with ash fallout 760,000 years ago.   view more (2007-03-06)

New research reveals why chili peppers are hot
Despite the popularity of spicy cuisine among Homo sapiens, the hotness in chili peppers has always been something of an evolutionary mystery.   view more (2008-08-12)

Radiation flashes may help crack cosmic mystery
Faint, fleeting blue flashes of radiation emitted by particles that travel faster than the speed of light through the atmosphere may help scientists solve one of the oldest mysteries in astrophysics.   view more (2007-12-04)

Complex Changes in the Brain's Vascular System Occur after Menopause
Many women experience menopausal changes in their body including hot flashes, moodiness and fatigue, but the changes they don't notice can be more dangerous.   view more (2008-06-17)

Evaluation metrics proposed for firefighter thermal imagers
Firefighters are starting to recognize the potential usefulness of thermal imagers or infrared cameras for saving property and lives.   view more (2005-12-27)

Poison + water = hydrogen. New microbial genome shows how
Take a pot of scalding water, remove all the oxygen, mix in a bit of poisonous carbon monoxide, and add a pinch of hydrogen gas. It sounds like a recipe for a witch's brew. It may be, but it is also the preferred environment for a microbe known as Carboxydothermus hydrogenoformans.   view more (2005-12-05)

Killer pulses help characterize special surfaces
Detecting deadly fumes in subways, toxic gases in chemical spills, and hidden explosives in baggage is becoming easier and more efficient with a measurement technique called surface-enhanced Raman scattering. To further improve the technique's sensitivity, scientists must design better scattering surfaces, and more effective ways of evaluating... view more... (2008-07-30)

The BMJ guide to wickedness
Need tips on "sexing up" poor performance data to meet government targets? Want advice to guarantee your dodgy drug sells like hot cakes? Or are you simply after ways to make a dubious but compelling submission to NICE? Several articles in this week's Christmas issue of the BMJ offer a comprehensive guide for the corrupt and incompetent.... view more... (2003-12-17)

'Hot' surgical techniques could increase postoperative haemorrhage after tonsillectomy (pp 642, 697)
The postoperative haemorrhage rate in tonsillectomies which use 'hot techniques' such as diathermy and coblation to stop bleeding could be over three times greater than operations which use cold steel techniques, conclude authors of a study in this week's issue of THE LANCET. Tonsillectomy is one of the most common surgical procedures.... view more... (2004-08-18)

Dark matter mystery deepens in cosmic 'train wreck'
Astronomers have discovered a chaotic scene unlike any witnessed before in a cosmic "train wreck" between giant galaxy clusters.   view more (2007-08-17)

ESA's XMM-Newton makes the first measurement of a dead star's magnetism
Using the superior sensitivity of ESA's X-ray observatory, XMM-Newton, a team of European astronomers has made the first direct measurement of a neutron star's magnetic field. The results provide deep insights into the extreme physics of neutron stars and reveal a new mystery yet to be solved about the end of this star's life. A neutron star is... view more...

Earth-like planets may be more common than once thought, says new U. of Colorado-Penn State study
More than one-third of the giant planet systems recently detected outside Earth's solar system may harbor Earth-like planets, many covered in deep oceans with potential for life.   view more (2006-09-08)

Prostate cancer patients undergoing hormone therapy may experience cognitive effects
A recent review of the literature has found that hormone deprivation therapy, a commonly used treatment for prostate cancer, may have subtle adverse effects on cognition in patients-- such as in the ability to recall and concentrate.   view more (2008-07-28)

Wired for sound: How the brain senses visual illusions
In a study that could help reveal how illusions are produced in the brain's visual cortex, researchers at the UCSD School of Medicine have found new evidence of rapid integration of auditory and visual sensations in the brain.   view more (2007-04-12)

Timing of start of hormone therapy may have effect on risk of coronary heart disease
Women who initiate hormone therapy closer to menopause tend to have a reduced risk of coronary heart disease compared to women who begin treatment further from menopause.   view more (2007-04-04)

At the root of nutrient limitation, ecosystems are not as different as they seem
Anyone who has thrown a backyard barbecue knows that hot dogs are inexplicably packaged in different numbers than buns - eight hot dogs per pack versus 10 hot dog buns. Put in ecological terms, this means that weenie roasts are "hot-dog limited" - the extra buns are worthless without hot dogs to fill them.   view more (2007-11-09)

Not So Different After All: Mysterious Eye Cells Adapt To Light
A new retinal photoreceptor adjusts its sensitivity in different lighting conditions, according to scientists at Brown University, where the rare eye cells were discovered.   view more (2006-01-06)

Clearest video of lightning-generated 'sprites' high above thunderstorms captured
Researchers at Duke University's Pratt School of Engineering have captured the best images ever produced of "sprites" - mysterious flashes of light resembling giant undulating jellyfish that can occur above strong thunderstorms - using a high-speed camera that recorded thousands of video frames a second.   view more (2006-02-16)

Cookie cutter in the sky
Black holes can now be thought of as donut holes. The shape of material around black holes has been seen for the first time: an analysis of over 200 active galactic nuclei-cores of galaxies powered by disks of hot material feeding a super-massive black hole-shows that all have a consistent, ordered physical structure that seems to be independent... view more...
