Smaller Portions Work As Well As Larger Portions In Delaying Hunger And Craving
Date: Feb-01-2013How much chocolate would you need to eat to be satisfied? Less than half as much as you think, according to this recently published Cornell University snacking study. Using chocolate chips, apple pie, and potato chips, researchers Ellen van Kleef, Mitsuru Shimizu, and Brian Wansink designed a study to determine if people who were given smaller portions of snack foods would feel hungrier or satisfied fifteen minutes after eating. Two groups with different portion sizes were tested...
Study Shows How Brain Cells Shape Temperature Preferences
Date: Feb-01-2013While the wooly musk ox may like it cold, fruit flies definitely do not. They like it hot, or at least warm. In fact, their preferred optimum temperature is very similar to that of humans - 76 degrees F. Scientists have known that a type of brain cell circuit helps regulate a variety of innate and learned behavior in animals, including their temperature preferences. What has been a mystery is whether or not this behavior stems from a specific set of neurons (brain cells) or overlapping sets...
The Evolution Of Complexity
Date: Feb-01-2013By simulating 25,000 generations of evolution within computers, Cornell University engineering and robotics researchers have discovered why biological networks tend to be organized as modules - a finding that will lead to a deeper understanding of the evolution of complexity. (Proceedings of the Royal Society, Jan. 30, 2013.) The new insight also will help evolve artificial intelligence, so robot brains can acquire the grace and cunning of animals...
Memory Network Revealed By In-Brain Monitoring
Date: Feb-01-2013Working with patients with electrodes implanted in their brains, researchers at the University of California, Davis, and The University of Texas Health Science Center at Houston (UTHealth) have shown for the first time that areas of the brain work together at the same time to recall memories. The unique approach promises new insights into how we remember details of time and place. "Previous work has focused on one region of the brain at a time," said Arne Ekstrom, assistant professor at the UC Davis Center for Neuroscience...
'Brewing' New Medicines?
Date: Feb-01-2013Researchers employing a century-old observational technique have determined the precise configuration of humulones, substances derived from hops that give beer its distinctive flavor. That might not sound like a big deal to the average brewmaster, but the findings overturn results reported in scientific literature in the last 40 years and could lead to new pharmaceuticals to treat diabetes, some types of cancer and other maladies...
Medications To Combat Infection And Pain Inspired By Ocean-Dwelling Shipworms And Cone Snails
Date: Feb-01-2013OHSU researchers, in partnership with scientists from several other institutions, have published two new research papers that signal how the next class of powerful medications may currently reside at the bottom of the ocean. In both cases, the researchers were focused on ocean-based mollusks - a category of animal that includes snails, clams and squid and their bacterial companions. Sea life studies aid researchers in several ways, including the development of new medications and biofuels...
Potential Health Risk To Mothers' And Babies' - High Levels Of Stress Experienced By Low-Income Pregnant Women In Rural Areas
Date: Feb-01-2013Stress during pregnancy puts mothers' and their babies' health at risk, previous research has shown. Now, a University of Missouri study indicates low-income pregnant women in rural areas experience high levels of stress yet lack appropriate means to manage their emotional and physical well-being. Health providers should serve as facilitators and link rural women with resources...
Medical School Gift Restriction Policies Linked To Subsequent Prescribing Behaviour
Date: Jan-31-2013Prescribing rates reduced among students exposed to active restriction policies Doctors who graduate from medical schools with an active policy on restricting gifts from the pharmaceutical industry are less likely to prescribe new drugs over existing alternatives, suggests a study published on bmj.com today. Medical school policies that restrict gifts to physicians from the pharmaceutical and device industries are becoming increasingly common, but the effect of such policies on physician prescribing behaviour after graduation into clinical practice is unknown...
Training Bystanders To Spot Drug Overdoses Can Reduce Deaths
Date: Jan-31-2013Educational program key to addressing the epidemic of opioid overdoses Training bystanders to recognize and respond to drug overdoses can significantly reduce the number of fatalities, finds a study published on bmj.com today. Overdoses of opioid drugs are a major cause of emergency hospital admissions and preventable death in many countries. In Massachusetts, annual opioid-related overdose deaths have exceeded motor vehicle deaths since 2005, so several strategies have been introduced to tackle this growing problem...
BMI - Is The Body Mass Index Formula Flawed?
Date: Jan-31-2013BMI (Body Mass Index) has been used for over 100 years in population studies, by doctors, personal trainers, and other health care professionals, when deciding whether their patients are overweight. However, BMI has one important flaw - it does not measure your overall fat or lean tissue (muscle) content. Body Mass Index, derived from a simple math formula, was devised in the 1830s by Lambert Adolphe Jacques Quetelet (1796-1874), a Belgian astronomer, mathematician, statistician and sociologist...
