Pseudomonas aeruginosa has broken the immune system's code

The human opportunistic pathogen, Pseudomonas aeruginosa, has broken the immune system's code, report researchers from the University of Chicago, enabling the bacteria to recognize when its host is most vulnerable and to launch an attack before the weakened host can muster its defenses.

Defect in the mechanics of motors that build tiny cellular hairs is the basis of Bardet-Biedl syndrome

A defect in the mechanics of motors that build tiny cellular hairs is the basis of a serious genetic disorder, according to researchers at UC Davis and Simon Fraser University, Canada.

Discovery sheds light on how a low-calorie diet extends lifespan

Mice, rats, worms, flies, and yeast all live longer on a low-calorie diet, which also seems to protect mammals against cancer and other aging-related diseases.

New insight into how protein E75 may control circadian rhythms and metabolic processes

University of Toronto researchers have gained new insight into how a specific protein may control circadian rhythms and metabolic processes, which has implications for treating cholesterol-related diseases.

Scientists discover genes linked to spread of breast cancer

In new research scientists have identified genes which enable breast cancer cells to spread to the lungs, and the discovery could very well improve diagnosis and treatment of the disease.

Cats have no sweet tooth

According to British and U.S. scientists cats may like ice cream, but it is not the sugary taste that appeals to them, because they are genetically unable to taste sweet flavors.

Participants in the gene therapy market discover new ways to improve clinical efficiency and generate revenue

The gene therapy market has had limited success with products during the clinical development process. Due to toxicological complications and poor therapy efficacy, healthcare authorities have suspended several gene therapy trials worldwide.

$4.7million grant for research on neuroblastoma

Significant funding from Australia's National Health and Medical Research Council will enable researchers at Children’s Cancer Institute Australia (CCIA) for Medical Research to make progress on the treatment of one the most aggressive, drug-resistant childhood cancers - neuroblastoma - over the next five years.

Bone marrow may be source of new egg-cell generation

Last year a group of Massachusetts General Hospital (MGH) researchers announced surprising findings that female mice - contrary to longstanding theories of mammalian reproductive physiology - retained the ability to make new egg cells or oocytes into adulthood.

If you're a worm, and stressed as well - its not good!

According to U.S. scientists how well you respond to stress predicts how long you will live, at least if you are a worm.

Spotting that nasty taste could well have saved our lives

Being able to distinguish the sweetness of oranges from the bitter taste of lemons may have evolved as a protection against eating poisonous plants, according to new genetic research.

Mate Choice and Friendship in Twins: Evidence for Genetic Similarity

How alike are you and your husband or wife - or, you and your best friend? Probably more alike than you realize. A study of twins shows that people's spouses and best friends are much more similar to them than was previously recognized - about as close as brothers and sisters. The research also suggested that the preference for partners who are similar to us is partly due to our genes.

Nerve-insulating substance called myelin can lead to functional improvements in animals with spinal cord injury

Combining partially differentiated stem cells with gene therapy can promote the growth of new "insulation" around nerve fibers in the damaged spinal cords of rats, a new study shows.

Single protein regulates secretion levels - helps stem cells become secretory cells

Johns Hopkins researchers have discovered that a single protein regulates secretion levels in the fruit fly's salivary gland and its skin-like outer layer.

Potential new treatment for nerve damage caused by diabetes

Research into a new treatment for nerve damage caused by diabetes could bring relief to millions of diabetic patients, say experts.

Molecular link between a viral infection and development of a common and fatal form of liver cancer

Researchers at The University of Texas M. D. Anderson Cancer Center have uncovered a crucial molecular link between a viral infection and development of a common and fatal form of liver cancer. In the process, they have identified a possible way to treat this disease as well as a number of other cancers.

Neuroscientists identify how the brain processes and stores emotional experiences as long-term memories

The research, performed on rats, could help neuroscientists better understand why emotionally arousing events are remembered over longer periods than emotionally neutral events, and may ultimately find application in treatments for conditions such as post-traumatic stress disorder.
