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

Omega 3 fatty acids have protective benefits when taken during pregnancy, study suggests (August 5, 2011) -- A new study suggests consuming Omega 3 fatty acids during pregnancy helps protects babies against illness during early infancy. The randomized, placebo-controlled trial followed approximately 1,100 pregnant women and 900 infants in Mexico. The women were supplemented daily with 400 mg of Docosahexaenoic Acid (DHA) supplements in the algal form or placebo from 18 to 22 weeks gestation through childbirth. Those whose mothers took DHA supplements had fewer colds and shorter illnesses at one, three and six months of age. ... > full story

Wireless network in hospital monitors vital signs, even as patients move about (August 5, 2011) -- A clinical warning system undergoing a feasibility study will include wireless sensors that take blood oxygenation and heart-rate readings from at-risk patients once or twice a minute. The data and lab results in the electronic medical record will be continually scrutinized by a machine-learning algorithm looking for signs of clinical deterioration. If any such signs are found, the system will call a nurse on a cellphone, alerting the nurse to check on the patient. ... > full story

How to eliminate motion sickness on tilting trains (August 5, 2011) -- Scientists have found that motion sickness on tilting trains can be essentially eliminated by adjusting the timing of when the cars tilt as they enter and leave the curves. They found that when the cars tilt just at the beginning of the curves instead of while they are making the turns, there was no motion sickness. ... > full story

Northern humans had bigger brains, to cope with the low light levels, study finds (August 5, 2011) -- The farther that human populations live from the equator, the bigger their brains, according to a new study. But it turns out that this is not because they are smarter, but because they need bigger vision areas in the brain to cope with the low light levels experienced at high latitudes. ... > full story
