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)
Old pulsars still have new tricks to teach us
The super-sensitivity of ESA's XMM-Newton X-ray observatory has shown that the prevailing theory of how stellar corpses, known as pulsars, generate their X-rays needs revising. view more (2006-07-26)
Molecular Anatomy of Influenza Virus Detailed
Scientists at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health in Bethesda, Md., and colleagues at the University of Virginia in Charlottesville have succeeded in imaging, in unprecedented detail, the virus that causes influenza. view more (2007-01-02)
Caltech biologists spy on the secret inner life of a cell
The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. view more (2008-10-13)
Study validates Pittsburgh Compound-B in identifying Alzheimer's disease brain toxins
A groundbreaking study conducted by University of Pittsburgh Alzheimer's disease researchers reported in the journal Brain (currently online) confirms that Pittsburgh Compound-B (PiB) binds to the telltale beta-amyloid deposits found in the brains of patients with Alzheimer's disease. view more (2008-03-27)
Brookhaven Scientists Explore Brain's Reaction to Potent Hallucinogen
Brain-imaging studies performed in animals at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory provide researchers with clues about why an increasingly popular recreational drug that causes hallucinations and motor-function impairment in humans is abused. view more (2008-04-29)
Does Stimulant Treatment for ADHD Increase Risk of Drug Abuse?
Parents, doctors, and others have wondered whether common treatments for attention-deficit hyperactivity disorder (ADHD) inadvertently predispose adolescents to future drug abuse. view more (2007-06-19)
Why dishing does you good: U-M study
Why does dishing with a girlfriend do wonders for a woman's mood? view more (2009-06-03)
Mechanoluminescence event yields novel emissions, reactions
Researchers at the University of Illinois report that a new study of mechanoluminescence revealed extensive atomic and molecular spectral emission not previously seen in a mechanoluminescence event. view more (2007-05-09)
DARESBURY REPORT SHOWS ROAD TO CLEANER TRANSPORT
Future global targets on reducing emissions of greenhouse gases may be more easily met thanks to new research on catalysts for fuel cells, published today in the new annual report from Daresbury Laboratory’s Synchrotron Radiation Department. Tough emission targets are driving the development of zero emission vehicles such as electric cars.... view more... (2000-12-11)
Quantitative PET Imaging Finds Early Determination of Effectiveness of Cancer Treatment
With positron emission tomography (PET) imaging, seeing is believing: Evaluating a patient's response to chemotherapy for non-Hodgkin lymphoma (NHL) typically involves visual interpretation of scans of cancer tumors. view more (2007-10-24)
Ghostly glow reveals galaxy clusters in collision
A team of scientists, including astronomers from the Naval Research Laboratory (NRL), have detected long wavelength radio emission from a colliding, massive galaxy cluster which, surprisingly, is not detected at the shorter wavelengths typically seen in these objects. view more (2008-10-16)
X-rays provide a new way to investigate exploding stars
ESA's X-ray observatory XMM-Newton has revealed a new class of exploding stars - where the X-ray emission 'lives fast and dies young'. view more (2007-05-10)
Molecular imaging enables earlier, individualized treatment of thyroid cancer
In a study to determine the diagnostic value of molecular imaging in nodal staging of patients with thyroid cancer, researchers were able for the first time to accurately distinguish between cancerous cells in regional lymph nodes and normal residual thyroid tissue directly after surgery. view more (2009-01-05)

Study offers clues to brain's protective mechanisms against alcoholism
Why do some people with a strong family history of alcoholism develop alcohol dependency while others do not? A new study provides clues that differing brain chemistry may provide part of the answer. view more (2006-09-05)
Getting better visualization of joint cartilage through cationic CT contrast agents
In its quest to find new strategies to treat osteoarthritis and other diseases, a Boston University-led research team has reported finding a new computer tomography contrast agent for visualizing the special distributions of glycosaminoglycans (GAGs) - the anionic sugars that account for the strength of joint cartilage. view more (2009-09-02)
Loss of tumor supressor gene essential to transforming benign nerve tumors into cancers
Researchers at UCLA's Jonsson Comprehensive Cancer Center showed for the first time that the loss or decreased expression of the tumor suppressor gene PTEN plays a central role in the malignant transformation of benign nerve tumors called neurofibromas into a malignant and extremely deadly form of sarcoma. view more (2009-10-13)
Plant Tomogram
New methods have emerged lately that allow to examine images of a living tissue without cutting it off an animal or a plant. The most advanced of them is the optical coherent tomography (OCT) method. The OCT device has been built and tried on plants by scientists from Nizhni Novgorod. Living tissues are turbid. They are almost impervious to the... view more... (2004-03-02)
Smoking damages key regulatory enzyme in the lung
Smoking appears to reduce a key enzyme in the lungs, possibly contributing to some of smoking's deleterious health effects. view more (2005-09-06)
