New findings on how brain processes visual information

Neuroscientists have long believed that vision is processed in the brain along circuits made up of neurons, similar to the way telephone signals are transferred through separate wires from one station to another.

Good signal for liver tumour therapy

The linking of two signalling pathways in the cells of liver tumours has a clear influence on their malignancy. Activation of the platelet-derived growth factor (PDGF) messenger molecule is decisive for this linking.

A run to the coffee shop may prevent skin cancer

Researchers in the United States have discovered that the combination of daily exercise and a cup of coffee may help prevent skin cancer.

Booze boosts bowel cancer risk

Drinking a daily pint of beer or a large glass of wine increases your risk of bowel cancer by around 10 per cent - according to a new report by Cancer Research UK.

Genome detectives discover culprits in multiple sclerosis

Genome detectives have done it again by revealing at least three genes which are implicated in the incurable nerve disorder Multiple Sclerosis (MS).

FOXP3 gene found to be involved in breast cancer

Researchers at the University of Michigan Comprehensive Cancer Center have identified a gene linked to the development of an aggressive form of breast cancer.

Researchers watch bacteria and antibiotics at the atomic level

A new understanding of an enzyme important for the transfer of genetic information in bacteria may help scientists improve current antibiotics and also create antibiotics that are less vulnerable to resistance.

New target for drugs to fight the HIV/AIDS virus

Researchers from Rome, Italy, describe a finding in the August 2007 print issue of The FASEB Journal that could lead to new drugs to fight the HIV/AIDS virus, as well as new vaccines to prevent infection.

New view on role of protein synthesis in memory formation

New research from the University of Illinois challenges the premise that the brain must build new proteins in response to an experience for that experience to be recorded in long-term memory.

Fish oil better than vegetable oil for your health

Scientists have provided new evidence that using more fish oil than vegetable oil in the diet decreases the formation of chemicals called prostanoids, which, when produced in excess, increase inflammation in various tissues and organs.

Researchers track how a single molecule of RNA or DNA unwinds

The process by which genes are duplicated is mysterious and complex, involving a cast of characters with diverse talents and the ability to play well with others in extremely close quarters.

Gene expression pattern could lead to improved treatment of pediatric septic shock

A consortium of researchers headed by Cincinnati Children's Hospital Medical Center has discovered a gene expression pattern that could lead to improved diagnosis and treatment of pediatric septic shock , still a serious public health problem despite today's potent antibiotics and pediatric intensive care units.

Tonsil epithelial factors may influence oropharyngeal HIV transmission

Current research demonstrates that the tonsils may possess the necessary factors to act as a transmission site for the spread of HIV.

Gut bacteria boost immune response to tumors

One potent, immune-based treatment for cancer is total body irradiation (TBI). This approach first depletes the body of the population of immune cells known as lymphocytes and then involves the adoptive transfer of tumor-specific T cells to the patient.

New findings on gene-transcription machinery

For some time, scientists have been tracking down the sequence of biochemical steps required to attract and assemble at the head end of a gene the molecular machinery needed to transcribe that gene to put to work the information it encodes.

Discovery of key HIV protein which makes cell membranes bend more easily

Carnegie Mellon University scientists have made an important discovery that aids the understanding of why HIV enters immune cells with ease.

Call for EU to launch major project to map out all our proteins

Biologists still have no clear idea how many active genes there are coding for proteins in humans and other organisms, even though for some species the genomes have been completely sequenced.

Air pollution has a role to play in atherosclerosis

Should we be watching our exposure to airborne pollution as well as our cholesterol levels?

Researchers improve accuracy of thyroid hormone testing

Researchers at Georgetown University Medical Center have developed a fast and accurate way to measure a major hormone released by the thyroid gland--an advance they say may help in the treatment of many women who have overactive or underactive thyroid glands.
