Menstruation proves more than a curse
The cells which thicken the womb wall during a woman's menstrual cycle contain a newly discovered type of stem cell, and could be used in the treatment of damaged and/or old tissue. view more (2007-11-15)
Researcher invents lethal 'lint brush' to capture and kill cancer cells in the bloodstream
In a new tactic in the fight against cancer, Cornell researcher Michael King has developed what he calls a lethal "lint brush" for the blood -- a tiny, implantable device that captures and kills cancer cells in the bloodstream before they spread through the body. view more (2008-12-12)
Dampened hopes for transplanting bone marrow stem cells in heart attacks
There is little, if any, evidence that adult stem cells can build other cells in an adult organism than those formed in the organs they themselves come from. At any rate, blood stem cells do not convert to heart muscle cells in a damaged heart, which was previously hoped. This has been shown by a research team from the Stem Cell Center at Lund... view more... (2004-05-06)
U of MN researchers turn cord blood into lung cells
Researchers at the University of Minnesota have, for the first time, coaxed umbilical cord blood stem cells to differentiate into a type of lung cell. view more (2006-11-02)
History of migraines associated with increased risk of retinopathy
Middle-aged men and women with a history of migraine and other headaches are more likely to have retinopathy, damage to the retina of the eye which can lead to severe vision problems or blindness, than those without a history of headaches, according to a study from the University of North Carolina at Chapel Hill. view more (2007-05-15)
Largest collection of anomalous white dwarfs observed in new Hubble images
Twenty-four unusual stars, 18 of them newly discovered, have been observed in new Hubble telescope images. The stars are white dwarfs, a common type of dead star, but they are odd because they are made of helium rather than the usual carbon and oxygen. This is the first extensive sequence of helium-core white dwarfs to be observed in a globular... view more... (2009-04-23)
UBC astronomers discover how white dwarf stars get their 'kicks'
University of British Columbia astronomer Harvey Richer and UBC graduate student Saul Davis have discovered that white dwarf stars are born with a natal kick, explaining why these smoldering embers of Sun-like stars are found on the edge rather than at the centre of globular star clusters. view more (2007-12-05)
Hodgkin lymphoma -- new characteristics discovered
Researchers are still discovering new characteristics of Hodgkin lymphoma, a common form of cancer of the lymphatic system. The malignant cells are derived from white blood cells (B cells), but have lost a considerable part of the B cell-specific gene expression pattern. view more (2008-10-09)
Brush your teeth to reduce the risk of heart disease
Heart disease is the leading cause of death worldwide. However, many people with cardiovascular disease have none of the common risk factors such as smoking, obesity and high cholesterol. view more (2008-09-09)
Researchers Create Model of Cancer-Preventing Enzyme, Study How It Works
Proline dehydrogenase is important because it plays a role in apoptosis, the process of cell death, by enabling the creation of superoxide, a highly reactive electron-rich oxygen species. view more (2007-05-14)
Shrinking giants, exploding dwarves
When white dwarf stars explode, they leave behind a rapidly expanding cloud of 'stardust' known as a Type Ia supernova. These exploding events, which shine billions of times brighter than our sun, are all presumed to be extremely similar, and thus have been used extensively as cosmological reference beacons to trace distance and the evolution of... view more...

Ability to cope with stress can increase 'good' cholesterol in older white men, study finds
Older white men who are better able to cope with stress experience higher levels of so-called "good cholesterol" than men who are more hostile or socially isolated, according to a study released at the 115th Annual Convention of the American Psychological Association. view more (2007-08-20)
Genetic abnormality may increase risk of blood disorders
Researchers at Memorial Sloan-Kettering Cancer Center (MSKCC) have shown for the first time that a tendency to develop some blood disorders may be inherited. view more (2009-03-16)
It may not be long before we see other worlds
WE MAY actually see a planet around a nearby star within the next six months. A team of British astronomers hope to achieve this feat by focusing their search on white dwarfs-dimly glowing stars at the end of their lives. Although more than 80 planets outside our Solar System have been discovered,... view more... (2002-03-06)
Minority patients prefer optical colonoscopy for colorectal cancer screening
The clinical importance of colorectal cancer screening is well established, however the majority of eligible people do not undergo screening tests. view more (2007-11-02)
Study to test drug's potential to preserve insulin production in newly diagnosed Type 1 diabetics
A drug used to treat lymphoma, rheumatoid arthritis and other immune disorders may enable newly-diagnosed type 1 diabetics to save some of their pancreas function and thereby reduce their susceptibility to long-term complications. view more (2006-03-16)
Acute respiratory disease poses significantly greater risk for black Americans
Black Americans are nearly twice as likely to develop acute lung injury, or ALI, as white Americans, according to researchers at the Emory University School of Medicine in Atlanta. view more (2009-05-20)
Skin defects set off alarm with widespread and potentially harmful effects
When patches of red, flaky and itchy skin on newborn mice led rapidly to their deaths, researchers at Washington University School of Medicine in St. Louis looked for the reason why. view more (2008-05-28)
Bone-marrow Cell Transplantation Could Save Limbs (p 427)
Injecting a patient’s bone-marrow cells into their legs could help repair damaged circulatory systems in those with limb ischaemia, suggest authors of a trial in this week’s issue of THE LANCET. Lower limb ischaemia is due to narrowing of the arteries and is a common condition, which if left untreated can lead to gangrene, amputation,... view more... (2002-08-07)
Exercise linked to reduced breast cancer risk
Both black women and white women who regularly exercise have a decreased risk of breast cancer compared to women who do not exercise. view more (2005-11-17)
