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.

Scientists create new brain cells - in a dish

Regenerative medicine scientists at the University of Florida's McKnight Brain Institute have created a system in rodent models that for the first time duplicates neurogenesis - the process of generating new brain cells - in a dish.

New study shows tiny RNAs intimately associated with cancer

In discoveries that may open a new chapter in understanding and diagnosing cancer, Howard Hughes Medical Institute (HHMI) investigators and their colleagues have established that tiny microRNAs provide a novel genetic route to the initiation of some forms of cancer.

The bacteria that cause food poisoning, bubonic plague, and whooping cough all deploy the same weapon to infect the body

A molecular "syringe" sticks out of the bacteria, pokes a hole in a nearby cell, and squirts in venomous proteins that hijack the cell's machinery.

Technology for analyzing gene expression must be standardized

Technology for analyzing gene expression must be standardized among laboratories and across platforms around the world to support this age of human genome exploration, an Oregon Health & Science University researcher says.

Scientists watch agents of brain-wasting diseases invade and move within brain cells

Scientists for the first time have watched agents of brain-wasting diseases, called transmissible spongiform encephalopathies (TSE), as they invade a nerve cell and then travel along wire-like circuits to points of contact with other cells.

New insight into the machinery cells use to internalize cell surface receptors

Using state of the art imaging technology a team from Yale School of Medicine has glimpsed one of the cell's most important 'nano-machines' in action. The work, performed in collaboration with English and French scientists, provides new insight into the machinery cells use to internalize cell surface receptors.

CAD system makes breast MRI more effective, efficient

A computer-aided detection (CAD) system is helping radiologists to more quickly and accurately determine the sizes and locations of cancers found on breast MRI—information that could change patients’ treatment, a new study shows.

Engineers have found a way to modify a plastic to anchor molecules that promote nerve regeneration, blood vessel growth or other biological processes

In the study led by Dr. Christine Schmidt, the researchers identified a piece of protein from among a billion candidates that could perform the unusual feat of attaching to polypyrrole, a synthetic polymer (plastic) that conducts electricity and has shown promise in biomedical applications.
