What shapes a bone? Diet and genetics dictate adult jaw shape (August 6, 2011) -- Researchers found that use over time and not just genetics informs the structure of jaw bones in human populations. The researchers say these findings may be used to predict the diet of an ancient population, even if little evidence exists in the fossil record. It can also make it easier for scientists to pinpoint the genetic relationship between fossils. ... > full story

Potential new eye tumor treatment discovered (August 6, 2011) -- New research demonstrates that a specific small segment of RNA could play a key role in the growth of a type of malignant childhood eye tumor called retinoblastoma. The tumor is associated with mutations of a protein called Rb, which is also involved with other types of cancers, including lung, brain, breast and bone. Their work could result in a new therapeutic target. ... > full story

Sentinel node biopsy safe, effective in head and neck melanomas, study finds (August 6, 2011) -- A common technique for determining whether melanoma has spread can be used safely and effectively even in tumors from the head and neck area, according to a new study. ... > full story

Mindless eating: Losing weight without thinking (August 6, 2011) -- Dieters may not need as much willpower as they think, if they make simple changes in their surroundings that can result in eating healthier without a second thought, said a consumer psychologist. ... > full story

Human-made fat may limit damage to heart attack victims (August 5, 2011) -- A human-made fat called Intralipid, which is currently used as a component of intravenous nutrition and to treat rare overdoses of local anesthetics, may also offer protection for patients suffering from heart attacks. ... > full story

Small molecules hit it big: New therapeutic approaches against viruses, bacteria, and cancer (August 5, 2011) -- Scientists have developed small molecules that inhibit the internalization of important signaling molecules but also of pathogenic organisms such as the immunodeficiency virus (HIV) and bacteria into cells. These compounds inhibit the function of the cellular scaffold protein clathrin und could thereby serve as a starting point for novel therapeutic approaches for the treatment of cancer, viral or bacterial infections, or neurological disorders. ... > full story

Neuroscientists identify how the brain remembers what happens and when (August 5, 2011) -- Neuroscientists have identified the parts of the brain we use to remember the timing of events within an episode. The study enhances our understanding of how memories are processed and provides a potential roadmap for addressing memory-related afflictions. ... > full story

Innate cells shown to form immunological 'memory' and protect against viral infection (August 5, 2011) -- Researchers have demonstrated that cells of the innate immune system are capable of "memory", and of mounting rapid protection to an otherwise lethal dose of live vaccinia virus. The study challenges previous thought that only B cells and T cells can store memory to ward off future infection. The finding has potentially significant consequences for the design of future vaccines, particularly for HIV. ... > full story

Molecular mechanisms offer hope for new pain treatments (August 5, 2011) -- By working with individuals suffering from a severe disorder that causes sensory neurons to degenerate, researchers have discovered how a specific genetic mutation causes their patients' condition, which in turn has revealed more information about the mechanisms in our bodies which enable us to sense pain. ... > full story

Gazpacho ingredients lose vitamin C during preparation (August 5, 2011) -- In summer, more dishes like gazpacho –- a cold soup containing raw vegetables, bread, olive oil and vinegar –- are consumed. A new study has revealed that ingredients’ vitamin C content as well as other organic acids is lower in the resulting mixture, meaning that it should be eaten immediately after preparation. ... > full story

A patient's own skin cells may one day treat multiple diseases (August 5, 2011) -- The possibility of developing stem cells from a patient's own skin and using them to treat conditions as diverse as Parkinson's disease, Alzheimer's disease and cancer has generated tremendous excitement in the stem cell research community in recent years. ... > full story

Researchers discover natural food preservative that kills food-borne bacteria (August 5, 2011) -- Researchers have discovered and received a patent for a naturally occurring lantibiotic -- a peptide produced by a harmless bacteria -- that could be added to food to kill harmful bacteria like salmonella, E. coli and listeria. ... > full story
