Near-normal blood sugar target did not delay risk of organ damage in people with diabetes, study finds (June 30, 2010) -- In people with longstanding type 2 diabetes who are at high risk for heart attack and stroke, lowering blood sugar to near-normal levels did not delay the combined risk of diabetic damage to kidneys, eyes, or nerves, but did delay several other signs of diabetic damage, a study has found. The intensive glucose treatment was compared with standard glucose control. ... > full story
When two parts of the Earth's crust break apart, this does not always cause massive volcanic eruptions (June 30, 2010) -- New research reveals that when two parts of the Earth's crust break apart, this does not always cause massive volcanic eruptions.

Large medical center reduces cumulative radiation exposure and CT scans through imaging algorithm, study finds (June 30, 2010) -- A large, academic medical center implemented an imaging algorithm that allowed radiologists to successfully reduce the cumulative radiation exposure and number of computed tomography (CT) angiography and CT perfusion studies performed on patients with aneurysmal subarachnoid hemorrhages (a form of stroke), according to a new study. ... > full story
Scholar calls for a new legal, ethical framework for research with human tissue specimens (June 30, 2010) -- A bioethics expert says a new legal and ethical framework needs to be placed around the donation and banking of human biological material, one that would more clearly define the terms of the material's use -- and address donor expectations before research begins. ... > full story
Combination MMRV vaccine linked with two-fold risk of seizures, study finds (June 29, 2010) -- The combination vaccine for measles, mumps, rubella and chickenpox is associated with double the risk of febrile seizures for 1- to 2-year-old children compared with same-day administration of the separate vaccine for measles, mumps and rubella and the varicella vaccine for chicken pox. Funded by the US Centers for Disease Control, the study analyzed 459,000 children 1 to 2 years old from numerous health systems across the US receiving their first dose of measles-containing vaccine. ... > full story
No link between diabetes drug rosiglitazone and increased rate of heart attack, study finds (June 29, 2010) -- The diabetes drug rosiglitazone has been under intense scrutiny since a 2007 study linked the drug's use with increased risk of heart attack and death from heart disease. Now, in a post-trial analysis of results from an international clinical trial of diabetes patients with cardiovascular disease, researchers at several major centers across the country report no increased rate of heart attack or death in patients taking the drug. ... > full story
Conscious choice of food can substantially mitigate climate change, research finds (June 29, 2010) -- Reducing the consumption of meat and dairy products and improving agricultural practices could decrease global greenhouse gas emissions substantially. By 2055 the emissions of methane and nitrous oxide from agriculture could be cut by more than eighty percent, researchers have found in a new modeling study. ... > full story
Despite countless changes, original HIV infection lurks within (June 29, 2010) -- Scientists have been surprised to learn that, despite thousands of changes that viruses like HIV undergo in rapid fashion to evade the body's immune system, the original version that caused the infection is still present in the body months later. ... > full story
Weight and children with developmental coordination disorder (June 29, 2010) -- Children with developmental coordination disorder are at greater risk of being overweight or obese, according to a new study. ... > full story
Age doesn't necessarily affect decision-making, study shows (June 29, 2010) -- Many people believe that getting older means losing a mental edge, leading to poor decision-making. But a new study shows that when it comes to making intuitive decisions -- using your "gut instincts" -- older adults fare as well as their juniors. The study found that education plays a key role as well. ... > full story
Surprising find may yield new avenue of treatment for painful herniated discs (June 29, 2010) -- An immune cell known to cause chronic inflammation in autoimmune disorders has been identified as a possible culprit in low back pain associated with herniated discs, according to doctors. ... > full story
Can too much HDL be harmful to women with type 1 diabetes? (June 29, 2010) -- Elevated blood levels of high-density lipoprotein (HDL) or "good" cholesterol, typically thought to protect against heart disease, may do the opposite in women with type 1 diabetes, according to new research. ... > full story
New formula gives first accurate peak heart rate for women (June 29, 2010) -- A new gender-based formula based on a large study provides a more accurate estimate of the peak heart rate a healthy woman should attain during exercise. It also will more accurately predict the risk of heart-related death during a stress test. Researchers found women's normal peak rate is lower than men's. ... > full story
New drugs to relieve cancer pain (June 29, 2010) -- Researchers in the UK and Italy have collaborated to develop new drugs which have the potential to relieve cancer pain without causing many of the side effects of current pain-treatments like morphine. ... > full story
