Breakthrough in understanding of hereditary disease of lymphatic vessels
(Helsinki, August 22nd) -- A study from the Ludwig Institute for Cancer Research (LICR) Affiliate Center at the University of Helsinki in Finland has shed light on the development of lymphatic vasculature and valves, and may help to develop better treatments for lymphedema. The disease, which... view more (2004-08-19)

'Use it or lose it'
Researchers from the Peninsula Medical School in Exeter, UK, have concluded a study that proves a direct link between levels of physical activity in middle age and physical ability later in life - regardless of body weight.   view more (2007-11-29)

Study says lung cancer overdiagnosis a result of screening
Screening for cancer can find tumors that might not otherwise have been diagnosed in a person's lifetime, a situation called overdiagnosis.   view more (2006-06-07)

Study shows how herpes infects cornea, evades immune cells
Herpes virus has an unusual strategy for infecting cornea cells that may also explain how it evades the immune system, according to a study by researchers at the University of Illinois at Chicago College of Medicine.   view more (2006-09-26)

One giant leap for space fashion: MIT team designs sleek, skintight spacesuit
In the 40 years that humans have been traveling into space, the suits they wear have changed very little. The bulky, gas-pressurized outfits give astronauts a bubble of protection, but their significant mass and the pressure itself severely limit mobility.   view more (2007-07-17)

Space is dusty, and now astronomers know why
Massive star supernovae have been major "dust factories" ever since the first generations of stars formed several hundred million years after the Big Bang, according to an international study published in Science Express today.   view more (2006-06-09)

Bird flu poses threat to international security, Illinois scholar says
In the past, when government leaders, policymakers and scholars have turned their attention to peace and security issues, the talk invariably has focused on war, arms control or anti-terrorism strategies. But Julian Palmore believes it's time to expand the scope of the conversation.   view more (2006-01-26)

Antibiotics may not be enough to stop recurrent gastric lymphoma caused by Helicobacter pylori
Research led by Dr. Anne Mueller at Stanford University School of Medicine demonstrates that successful eradication of Helicobacter may not prevent future aggressive gastric lymphoma since resting B cells are left behind.   view more (2005-08-25)

Radiation-killed bacteria vaccine induces broad immune response in mice
Vaccines made with bacteria killed by gamma irradiation, rather than by standard methods of heat or chemical inactivation, may be more effective, say researchers supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH).   view more (2006-07-26)

Cambridge led team discovers gene mutation which prevents carriers from feeling pain
Researchers have discovered a gene mutation which prevents the otherwise healthy carriers from sensing pain, after studying three related families with a rare genetic disorder in northern Pakistan.   view more (2006-12-14)

X-ray satellites discover the biggest collisions in the Universe
The orbiting X-ray telescopes XXM-Newton and Chandra have caught a pair of galaxy clusters merging into a giant cluster. The discovery adds to existing evidence that galaxy clusters can collide faster than previously thought.   view more (2007-07-18)

Optical vortex could look directly at extrasolar planets
A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star.   view more (2005-12-01)

An Anti-Frailty Pill for Seniors?
Researchers at the University of Virginia Health System report that a daily single oral dose of an investigational drug, MK-677, increased muscle mass in the arms and legs of healthy older adults without serious side effects, suggesting that it may prove safe and effective in reducing age-related... view more (2008-11-05)

Saturn's rings show evidence of a modern-day collision
Scientists on NASA's Cassini mission have spied a new, continuously changing feature that provides circumstantial evidence that a comet or asteroid recently collided with Saturn's innermost ring, the faint D ring.   view more (2006-10-12)

Robot wheelchair may give patients more independence
Engineers at the National Institute of Standards and Technology (NIST) are developing a robotic system that may offer wheelchair-dependent people independent, powered mobility and the ability, depending on patient status, to move to and from beds, chairs and toilets without assistance.   view more (2006-10-02)

Novel small molecule therapy shows benefit for anemic patients via hydration of red blood cells
Researchers are identifying innovative therapeutics for sickle cell anemia that focus on specific factors in the disease's progression, such as the important role of hydration of the red blood cells.   view more (2008-02-06)

Salt increases ulcer-bug virulence
Scientists have identified yet another risk from a high-salt diet. High concentrations of salt in the stomach appear to induce gene activity in the ulcer-causing bacterium Helicobacter pylori, making it more virulent and increasing the likelihood of an infected person developing a severe gastric... view more (2007-05-23)

Anthracyclines improve survival in HER2-positive breast cancer patients
Treatment with the class of chemotherapy drugs called anthracyclines improves survival in women with HER2-positive breast cancer who have previously had surgery, but it may not offer any benefit for women with HER2-negative tumors.   view more (2007-12-26)
