Mother tongue comes from your prehistoric father (September 17, 2011) -- Language change among our prehistoric ancestors came about via the arrival of immigrant men -- rather than women -- into new settlements, according to new research. ... > full story
Drug may increase cognition for people with Down syndrome (September 17, 2011) -- A researcher is conducting a clinical trial with a drug that may increase cognition in those with Down syndrome. ... > full story
T cells making brain chemicals may lead to better treatments for inflammation, autoimmune diseases (September 17, 2011) -- Scientists have identified a surprising new role for a new type of T cell in the immune system: some of them can be activated by nerves to make a neurotransmitter (acetylcholine) that blocks inflammation. The discovery of these T cells is novel and suggests that it may be possible to treat inflammation and autoimmune diseases by targeting the nerves and the T cells. ... > full story
New insight into impulse control (September 17, 2011) -- How the brain controls impulsive behavior may be significantly different than psychologists have thought for the last 40 years. ... > full story
Potential molecular target to prevent growth of cancer cells identified (September 17, 2011) -- Researchers have shown for the first time that the protein fortilin promotes growth of cancer cells by binding to and rendering inert protein p53, a known tumor suppressor. ... > full story
MRI research demonstrates ALS attacks multiple parts of the brain (September 17, 2011) -- Medical researchers demonstrate that ALS -- known as Lou Gehrig's disease -- damages neurons in parts of the brain responsible for cognition and behavior. The scientists provide evidence that ALS affects more than just the motor cortex, the part of the brain responsible for motor function. ... > full story
Moms who eat high-fat diet before, during pregnancy 'program' babies to be fat, at risk, mouse study shows (September 17, 2011) -- New research in mice indicates that babies born to moms who eat a high-fat diet before and during pregnancy have a higher fat mass and smaller livers than babies whose moms consume low-fat fare, according to scientists. ... > full story
Switch that controls stem cell pluripotency discovered (September 16, 2011) -- Scientists have found a control switch that regulates stem cell "pluripotency," the capacity of stem cells to develop into any type of cell in the human body. The discovery reveals that pluripotency is regulated by a single event in a process called alternative splicing. ... > full story
Yellow patches around eyelids predict risk of heart problems, study finds (September 16, 2011) -- Raised yellow patches of skin (xanthelasmata) around the upper or lower eyelids are markers of an individual's increased risk of having a heart attack or suffering from heart disease, a new study finds. ... > full story
Biochemical cell signals quantified: Data capacity much lower than expected, scientists find (September 16, 2011) -- Just as cell phones and computers transmit data through electronic networks, the cells of your body send and receive chemical messages through molecular pathways. The term "cell signaling" was coined more than 30 years ago to describe this process. For the first time, scientists have quantified the data capacity of a biochemical signaling pathway and found a surprise -- it's lower than a dial-up modem. ... > full story
Number of children poisoned by medication rising dramatically, study says (September 16, 2011) -- The number of young children admitted to hospitals or seen in emergency departments because they unintentionally took a potentially toxic dose of medication has risen dramatically in recent years, according to a new study. The rise in exposure to prescription products has been so striking that the U.S. Centers for Disease Control and Prevention has established the PROTECT Initiative, intended to prevent unintended medication overdoses in children. ... > full story
New class of stem cell-like cells discovered offers possibility for spinal cord repair (September 16, 2011) -- Scientists have announced the discovery of a new class of cells in the spinal cord that act like neural stem cells, offering a fresh avenue in the search for therapies to treat spinal cord injury and disease. ... > full story
