Study: K-complexes control effects of noise on sleep

During sleep, our perception of the environment decreases. However the extent to which the human brain responds to surrounding noises during sleep remains unclear. In a study published this week in Proceedings of the National Academy of Sciences (PNAS), researchers from University of Liège used brain imaging to study responses to sounds during sleep.

Breast cancer patients with BRCA1 mutation experience pCR after neoadjuvent chemotherapy

Nearly half of breast cancer patients carrying the BRCA1 gene mutation experience a complete pathological response (pCR) - the disappearance of all evidence of disease from the breast tissue and lymph nodes - regardless of disease stage after standard neoadjuvent chemotherapy, according to new research from The University of Texas MD Anderson Cancer Center.

Biologists reveal why men's ring fingers are longer than their index fingers

Biologists at the University of Florida have found a reason why men's ring fingers are generally longer than their index fingers - and why the reverse usually holds true for women.

Researchers reveal mechanism behind how cells communicate

Cell communication is essential for the development of any organism. Scientists know that cells have the power to "talk" to one another, sending signals through their membranes in order to "discuss" what kind of cell they will ultimately become - whether a neuron or a hair, bone, or muscle. And because cells continuously multiply, it's easy to imagine a cacophony of communication.

Researchers discover novel way to increase amounts of antibiotics

A novel way of increasing the amounts of antibiotics produced by bacteria has been discovered that could markedly improve the yields of these important compounds in commercial production. It could also be valuable in helping to discover new compounds. With the ever-growing threat from antibiotic resistance, these tools will be very useful in ensuring that we have enough of these useful compounds in the future.

Cancer cells with specific genetic defect extra susceptible to therapy that damages DNA

Using a strategy based on treating cancer cells that carry a specific genetic signature - hyper-expression of the protein Myc - with therapy that affects the stability of the cell's DNA, more effective results can be achieved.

C. sporogenes bacterium could be used as vehicle to deliver drugs in frontline cancer therapy

A bacterial strain that specifically targets tumours could soon be used as a vehicle to deliver drugs in frontline cancer therapy. The strain is expected to be tested in cancer patients in 2013 says a scientist at the Society for General Microbiology's Autumn Conference at the University of York.

Inflammation boosts activity of two proteins that can normalize blood sugar in diabetics

Increased low-grade inflammation in the body resulting from obesity is widely viewed as contributing to type 2 diabetes. Going against this long-held belief, researchers from Children's Hospital Boston report that two proteins activated by inflammation are actually crucial for maintaining good blood sugar levels - and that boosting the activity of these proteins can normalize blood sugar in severely obese and diabetic mice.

IKEPLUS immunization completely eliminates TB bacteria from infected tissues

A potential vaccine against tuberculosis has been found to completely eliminate tuberculosis bacteria from infected tissues in some mice. The vaccine was created with a strain of bacteria that, due to the absence of a few genes, are unable to avoid its host's first-line immune response.
