Fountain of youth from the tap? Environmental lithium uptake promotes longevity, scientists demonstrate in worms (February 18, 2011) -- A regular uptake of the trace element lithium can considerably promote longevity, suggests new research by scientists in Germany. The researchers have demonstrated by two independent approaches that even a low concentration of lithium leads to an increased life expectancy in humans as well as in a model organism, the roundworm Caenorhabditis elegans. ... > full story
Study links hypoxia and inflammation in many diseases (February 18, 2011) -- When the body is deprived of oxygen during a major surgery, the kidneys, heart muscles or lungs can be injured as a result. Yet the body can adapt to low oxygen. Understanding how can lead to cures. New research explores the relationship between lack of oxygen, called hypoxia, and the inflammation that can injure or kill some patients who undergo surgery. In a liver transplant, for example, the surgery and anesthesiology can go perfectly yet the new liver will fail because of hypoxia. ... > full story
Scientists bioengineer a protein to fight leukemia (February 18, 2011) -- Scientists have announced a breakthrough discovery in understanding how the body fights leukemia. They have identified a protein called CD19-ligand located on the surface of certain white blood cells that facilitates the recognition and destruction of leukemia cells by the immune system. This work represents the first report of a bioengineered version of CD19-L, a recombinant human biotherapeutic agent, targeting CD19-positive leukemic stem cells. ... > full story
Value of therapeutic hypothermia after cardiac arrest confirmed by new research (February 18, 2011) -- Researchers confirmed that patients who receive therapeutic hypothermia after resuscitation from cardiac arrest have favorable chances of surviving the event and recovering good functional status. In therapeutic hypothermia, a patient's body temperature is cooled to 33 degrees Celsius following resuscitation from cardiac arrest, in order to slow the brain's metabolism and protect the brain against the damage initiated by the lack of blood flow and oxygenation. ... > full story
High-caffeine-consuming boys get greater rush from caffeine than girls (February 18, 2011) -- Among the many differences between girls and boys, add the effects from caffeine -- physiological, behavioral and subjective -- to the list. ... > full story
Brain function linked to birth size; Study sheds light on mental health problems later in life (February 18, 2011) -- Scientists have discovered the first evidence linking brain function variations between the left and right sides of the brain to size at birth and the weight of the placenta. The finding could shed new light on the causes of mental health problems in later life. ... > full story
Identification of glaucoma gene brightens view for future therapies (February 18, 2011) -- Glaucoma -- a leading cause of vision loss and blindness worldwide -- runs in families. A team of investigators has identified a new candidate gene for the most common form of the eye disorder, primary open angle glaucoma. The findings offer novel insights into glaucoma pathology and could lead to targeted treatment strategies. ... > full story
Reverse genetics allow scientists to slow spread of Rubella virus (February 18, 2011) -- Scientists have identified the gene that allows the Rubella virus to block cell death and reverse engineered a mutant gene that slows the virus's spread. Researchers believed that RNA viruses were able to spread by blocking the pathways in cells that lead to cell suicide, and isolated the responsible gene in Rubella, also known as German measles. ... > full story
Children in public housing play outdoors more (February 18, 2011) -- Young children living in urban public housing spend more time playing outdoors than other urban children, according to researchers. ... > full story
Male fertility is in the bones: First evidence that skeleton plays a role in reproduction (February 18, 2011) -- Researchers have discovered that the skeleton acts as a regulator of fertility in male mice through a hormone released by bone, known as osteocalcin. ... > full story
Chemical guided missile could be the answer to wiping out cancer (February 18, 2011) -- Medical scientists in Australia have created the world's first cancer stem cell-targeting chemical missile, placing them a step closer to creating a medical 'smart bomb' that would seek out and eradicate the root of cancer cells. ... > full story
Portable pedal machines may help counter harmful effects of sedentary jobs (February 18, 2011) -- Portable pedal machines could help counter the harmful effects of prolonged periods spent at a desk or workstation among an increasingly sedentary workforce, suggests a small study published online in the British Journal of Sports Medicine. ... > full story
