Companies pushing 'toddler milk' need oversight, experts warn Posted: 14 Nov 2016 12:28 PM PST Liquid-based nutritional supplements, originally formulated for malnourished or undernourished children, need more regulatory oversight as they are increasingly marketed to promote growth in children generally, warn researchers.

'Sweet' solution kills E. coli in drinking water Posted: 14 Nov 2016 11:24 AM PST Paper strips laced with sugar could be the sweetest solution so far, literally, to kill E. coli in contaminated water. A researcher says the "DipTreat" discovery will be key to developing a new generation of inexpensive and portable water treatment devices, with human health benefits in Canada and around the world.

Scientists discover how protein senses touch Posted: 14 Nov 2016 11:23 AM PST A protein first discovered in 2010 is directly responsible for sensing touch, scientists have discovered. Knowledge about this protein, called Piezo 1, could be relevant for designing better pain medications and exploring future therapies for blood disorders, hypertension and more.

Teenage binge drinking can affect brain function of future offspring Posted: 14 Nov 2016 11:06 AM PST Repeated binge drinking during adolescence can affect brain functions in future generations, potentially putting offspring at risk for such conditions as depression, anxiety, and metabolic disorders, a study has found.

Repurposed drug may offer diagnosis, treatment for traumatic nerve damage Posted: 14 Nov 2016 07:57 AM PST Researchers believe they have identified a new means of enhancing the body's ability to repair its own cells, which they hope will lead to better diagnosis and treatment of traumatic nerve injuries, like those sustained in car accidents, sports injuries, or in combat. The team has demonstrated that a drug previously approved for other purposes can 'wake up' damaged peripheral nerves and speed repair and functional recovery after injury.

Immune system uses gut bacteria to control glucose metabolism Posted: 14 Nov 2016 07:56 AM PST Researchers have discovered an important link between the immune system, gut bacteria and glucose metabolism -- a "cross-talk" and interaction that can lead to type 2 diabetes and metabolic syndrome when not functioning correctly.

In the past, this was thought to be impossible -- the crystals, which have special magnetic properties, were so small that scientists could not control their movement. But now a team of Chinese researchers has found the solution, and their discovery has opened new applications that could use these crystals to improve -- and perhaps even save -- many lives.

Machine learning to help physicians Posted: 14 Nov 2016 05:22 AM PST Physicians have long used visual judgment of medical images to determine the course of cancer treatment. A new program package reveals changes in images and facilitates this task using deep learning.

Endocrine cells in the brain influence the optimization of behavior Posted: 14 Nov 2016 05:19 AM PST A person exposed to stress can usually rapidly adapt the own behavior to the specific situation. Biochemical messenger substances in the brain or so-called neurotransmitters play a central role in this rapid transformation process. We know that hormones also have a stress-regulating function, but that their effects are more slowly apparent. However, recent findings indicate that this may not actually be the case.

Long-term use of opioid patches common among persons with Alzheimer's disease Posted: 14 Nov 2016 05:19 AM PST Approximately seven per cent of persons with Alzheimer's disease use strong pain medicines, opioids, for non-cancer pain for a period longer than six months, according to a recent study.

Red is good: The brain uses color to help us choose what to eat Posted: 14 Nov 2016 05:19 AM PST Red means "Green light, go for it!" Green means: "hmm, better not!" Like an upside down traffic light in our brain, color helps us decide whether or not to eat something. This new study states that vision is the main sense we use to guide us in food choices. To evaluate calorie intake, we rely on a "color code."

Inherited taste perceptions may explain why some people eat too much salt Posted: 13 Nov 2016 01:03 PM PST People with enhanced bitter taste perception are almost twice as likely to consume too much sodium as people with less acute tasting ability. Those with gene variations that allow them to taste bitter more intensely may also taste salt more intensely and enjoy it more, leading to increased sodium intake, researchers said.

Recommendations regarding use of statins for the prevention of cardiovascular disease Posted: 13 Nov 2016 01:01 PM PST The U.S. Preventive Services Task Force (USPSTF) has issued a recommendation statement regarding the use of statins for primary prevention of cardiovascular disease in adults.
