Sperm testing in UK labs fails to meet World Health Organization standards

Teams from the Universities of Bristol and Sheffield found only five per cent of the clinics met all WHO standards for assessing the size and shape of sperm.

Pigment explains why red heads are more at risk of skin cancer

A team of scientists have discovered that tiny chemical differences in how our skin reacts to ultraviolet light could explain why red heads are more likely to suffer skin cancer.

Immune system more concerned with damage detected than foreign invaders, such as viruses

A well-respected researcher who is now a chief of an immunology laboratory of the National Institutes of Health (NIH) has rocked the boat in the past few years for the experts in the understanding of the autoimmune system.

New prostate cancer test could save thousands from unnecessary surgery

Doctors at present lack a test that can distinguish fast-developing tumours that need urgent attention from slow-growing ones that are not a threat and need only watching, and as a result many men have operations that can leave them impotent and incontinent for prostate tumours that would never have killed them.

Open nephron-sparing surgery remains the most desirable for the patients

Urologists often view less-invasive surgery techniques as more desirable for the patient, but in a study of open nephron-sparing surgeries (NSS) from 1985 to 2001 at Mayo Clinic, researchers found that the "gold standard" of open surgery for kidney tumors should remain the first choice for many patients. The study appears online today in The Journal of Urology.

Faster and more objective way to examine the surfaces of fossilized teeth

Using a powerful microscope and computer software, a team of scientists from Johns Hopkins, the University of Arkansas, Worcester Polytechnic Institute and elsewhere has developed a faster and more objective way to examine the surfaces of fossilized teeth, a practice used to figure out the diets of our early ancestors.

New breast cancer genes detected using cutting edge technology

Scientists in the UK say they have detected four new genes believed to be involved in the development of breast cancer.

New insights into dietary divergences between some of our human ancestors

A Penn State researcher is part of the team that developed techniques that have generated insights into dietary divergences between some of our human ancestors, allowing scientists to better understand the evolutionary path that led to the modern-day diets that humans consume.

Laser scissor-and-tweezers technology called RoboLase performed across the Pacific

In an effort to combine sophisticated laser and Internet technologies, scientists in Australia have successfully performed laser surgery and "optical trapping" in a Southern California laboratory via the Internet.

Tool helps determine who is at high risk of death after prostate cancer recurrence following surgery

Researchers at Johns Hopkins and The Brady Urological Institute have identified three risk factors and developed a simple reference tool that doctors can use to determine who is at high risk of death after prostate cancer recurrence following surgery.

Percutaneous core-needle biopsy, provides samples of tissue suitable for accurate initial diagnosis of a solid tumor

Inserting biopsy needles through the skin appears to be a safe and reliable alternative to surgery for obtaining diagnostic samples of a suspected solid tumor in children, according to results of a study by investigators at St. Jude Children's Research Hospital.

Benign breast disease - not necessarily an indicator of higher breast cancer risk

According to a new study, women diagnosed with a form of benign breast disease, but who do not have a strong family history of breast cancer, have no heightened risk of developing a tumor.

Startling discovery about the properties of human bone

The scientists describe their results - finding a sort of "glue" in human bone - in the cover story of the August issue of the international scientific journal, Nature Materials. The article was published on-line on July 17. It describes how healthy bone resists fracture and how unhealthy bone fractures at the molecular level.

Discovery of a chemical messenger called neuropeptide Y (NPY) in taste bud cells

The tongue's ability to differentiate between sweet and bitter tastes may reside in the same taste bud cells, a new study reports.

Nerve cells can also release neurotransmitters outside of synapses

Every neurobiology textbook invariably states that nerve cells communicate with each other through synapses, the specialized cell-cell contacts found at the end of the cells' threadlike extensions. In the journal Science, researchers at the Salk Institute for Biological Sciences and the University of California at San Diego report that nerve cells, or neurons, may not have to rely on traditionally defined synapses to "talk" to each other.

Biologists determine structure of a common-cold virus

Biologists at Purdue University have determined the combined structure of a common-cold virus attached to a molecule that enables the virus to infect its host, information that ultimately may help researchers develop methods for treating certain viral infections.

True validity of prostate cancer tests questioned

According to the American cancer society, more than 232,000 men will be diagnosed with prostate cancer this year, and about 30,000 will die of it.

Researchers use imaging to gain better understanding of cancerous cell behaviour

Thanks to imaging and analysis techniques used by researchers at TU Delft, an international group of scientists has been able to gain more insight into the behaviour of cancerous cells.

US scientists find "mother of all brain stem cells"

Scientists at the University of Florida have been able grow brain cells in the laboratory.

New technology developed at Cornell University could make it just as easy to identify genes

A supermarket checkout computer can identify thousands of different items by scanning the tiny barcode printed on the package. New technology developed at Cornell University could make it just as easy to identify genes, pathogens, illegal drugs and other chemicals of interest by tagging them with color-coded probes made out of synthetic tree-shaped DNA.
