Shape of a protein on the surface of pneumonia bacteria helps germs invade the human bloodstream

Scientists at St. Jude Children's Research Hospital have discovered that the shape of a protein on the surface of pneumonia bacteria helps these germs invade the human bloodstream.

Hirsute women most likely have androgen excess-related disorders, primarily polycystic ovary syndrome

Among women in their child-bearing years, even minimal amounts of unwanted hair in male-type patterns – especially in the presence of other subtle changes – may be a sign of a hormonal imbalance linked to a variety of serious side effects and medical conditions, according to the December 2004 issue of the American Journal of Obstetrics and Gynecology.

Needling chromosomes yields insights into cell division

By impaling individual chromosomes with glass needles one thousandth the diameter of a human hair, a Duke University graduate student has tested their "stickiness" to one another during cell division. Her uncanny surgical skills have added a piece to the large and intricate puzzle of how one cell divides into two -- a process fundamental to all organisms.

May soon be possible to identify people at risk and even to treat a heart problem with a drug that works on the brain

Sudden cardiac death from emotional stress may be triggered by uneven signals from the brain to the heart, according to a study by University College London (UCL) scientists published in the January issue of Brain.

Bacteria can use a sonar-like system to spot other cells

For the first time, scientists have found that bacteria can use a Sonar-like system to spot other cells (either normal body cells or other bacteria) and target them for destruction.

Evidence suggests that changes in the bacteria and fungi in the gastrointestinal tract can intensify the immune system's reaction to common allergens

If you want to avoid allergies or asthma, scientists at the University of Michigan Medical School suggest you start paying more attention to what's in your gut.

Somatic hypermutation (SHM) should prove to be extremely useful in directed protein evolution

Fascinated by the efficient way the human immune system generates a rapid response to create a near-infinite variety of antibodies, researchers have "hijacked" that machinery and used it to evolve a new type of fluorescent protein.

Researchers can now inexpensively program the chemical synthesis of entire genes on a single microchip

Devices the size of a pager now have greater capabilities than computers that once occupied an entire room. Similar advances are being made in the emerging field of synthetic biology at the University of Houston, now allowing researchers to inexpensively program the chemical synthesis of entire genes on a single microchip.

40-year tale of investigation and innovation into the challenge of hip implant failure

A remarkable story of how a new disease was inadvertently caused by successful medical treatment, ultimately understood, and eventually defeated by scientific innovation is being told a major player in the process.

Fluorescent colors used to separate cells visually

The latest holiday gifts being offered to the scientific community this season by scientists in the laboratory of Howard Hughes Medical Institute investigator Roger Y. Tsien come in a dazzling variety of hues -- cherry, strawberry, tangerine, tomato, orange, banana and honeydew. The color spectrum would make Pantone proud.

New research shows that cancer patients can not intentionally postpone death to survive for significant personal events

Contrary to previous reports, new research shows that cancer patients can not intentionally postpone death to survive for significant personal events such as Christmas, Thanksgiving or a birthday, according to a study in the December 22/29 issue of JAMA.

Drinking water with high levels of arsenic increases risk of lung cancer

Residents of Taiwan who consumed drinking water with high levels of arsenic have a higher risk of lung cancer, with cigarette smokers from this group having an even greater risk, according to a study in the December 22/29 issue of JAMA.

22 Dec 2004

Relatives of lung cancer patients up to 3.5 times greater risk of developing lung cancer

First-degree relatives of lung cancer patients have a 2 to 3.5 times greater risk of developing lung cancer than the general population, and tobacco smoke plays a major role, even among those with a genetic predisposition, according to a study in the December 22/29 issue of JAMA.
