Organic Food Has No More Nutritional Value Than Food Grown With Pesticides, Study Shows (August 9, 2008) -- New research in the Journal of the Science of Food and Agriculture shows there is no evidence to support the argument that organic food is better than food grown with the use of pesticides and chemicals. The study looked at the following crops – carrots, kale, mature peas, apples and potatoes – staple ingredients that can be found in most families’ shopping list. ... > full story
People With Heart Disease Still Have Trouble Controlling Blood Lipid Levels (August 9, 2008) -- Despite some improvements to lower "bad" cholesterol levels, people with cardiovascular diseases still need to do a better job controlling overall blood lipid levels. ... > full story
Diet And Autism Research Focuses On Which Foods May Affect Autistic Behavior (August 9, 2008) -- Can autism be "cured" with diet? Researchers at the University of Texas Health Science Center at Houston embark on a double-blind study to find out if wheat and dairy products can affect autistic behavior, as some parents believe. ... > full story
If Your First Cigarette Gave You A Buzz And You Now Smoke, A Gene May Be To Blame (August 9, 2008) -- Anyone who has ever tried smoking probably remembers that first cigarette vividly. Now, a new study links those first experiences with smoking, and the likelihood that a person is currently a smoker, to a particular genetic variation. The finding may help explain the path that leads from that first cigarette to lifelong smoking. ... > full story
Trigger For Brain Plasticity Identified: Signal Comes, Surprisingly, From Outside The Brain (August 9, 2008) -- Researchers have long sought a factor that can trigger the brain's ability to learn -- recapturing the "sponge-like" quality of childhood. Called Otx2, it causes a key type of cell in the cortex to mature, initiating a critical period -- a window of heightened brain plasticity, when the brain can readily make new connections ... > full story
Putting MicroRNAs On The Stem Cell Map (August 9, 2008) -- Short snippets of RNA called microRNAs help to keep embryonic stem cells in their stem cell state. Researchers now have discovered the gene circuitry that controls microRNAs in embryonic stem cells. Mapping the control circuitry of stem cells reveals how they maintain themselves or decide to differentiate, providing key clues for regenerative medicine and reprogramming of adult cells to a stem cell state. These maps also aid our understanding of human development and diseases such as cancer. ... > full story
Robotics Research: Enhancing The Lives Of People With Disabilities (August 9, 2008) -- Robots may be the solution for people with disabilities who are struggling to regain the use of their limbs. ... > full story
Tuning In To A New Language On The Fly: Effects Of Context And Seasonality On Songbird Brain (August 9, 2008) -- New research has shown that exposure to a changed acoustic and social environment can rewire the way the brain processes sounds. Study of the responses of individual brain cells has shown that they respond best to a particular frequency (pitch) of sound, less well to nearby frequencies, and poorly to distant sound frequencies. ... > full story
Beyond PTEN: Alternate Genes Linked To Breast, Thyroid And Kidney Cancer Predisposition (August 9, 2008) -- A new discovery may lead to more effective screening and treatment for patients with a difficult to recognize syndrome characterized by tumor-like growths and a high risk of developing specific cancers. The research is the first in over thirteen years to identify an alternate susceptibility gene for Cowden syndrome and related disorders. ... > full story
New Approach To Ad Hoc Networks For First Responders Debuts (August 9, 2008) -- Researchers successfully demonstrated a prototype approach to maintain two-way communications with first responders as they make their way in building fires, and mine and tunnel collapses. ... > full story
82 Percent Of Americans Think Health Care System Needs Major Overhaul (August 9, 2008) -- Americans are dissatisfied with the US health care system and 82 percent think it should be fundamentally changed or completely rebuilt, according to a new survey. ... > full story
Multi-tasking Molecule Holds Key To Allergic Reactions (August 8, 2008) -- As the summer approaches most of us rejoice, reach for the sunscreen and head outdoors. But an ever-growing number of people reach for tissue instead as pollen leaves eyes watering, noses running and spirits dwindling. Hay fever is just one of a host of hypersensitivity allergic diseases that cause suffering worldwide and others, such as severe reactions to bee stings or eating peanuts, can be more serious and even fatal. ... > full story
