[Unlikely] Loaned Sweatshirt Leads to Robbery Arrests
A sweatshirt loaned to a friend two years ago led to the arrest of two people for a series of robberies in Indiana. Chloride increases response to pheromones and odors in mouse sensory n
How an individual vomeronasal sensory neuron (VSN) transduces chemical signals into electrical signals has been a mystery. Researchers now show that chloride acts as a major amplifier for signal transduction in mouse VSNs, increasing the responsiveness to pheromones or odorants. Video Voice for the Voiceless
Filmmakers using relatively cheap digital technology throw a harsh light on the plight faced by indigenous societies trying to survive the intrusion of a modern world. Jason Silverman reports from New York. Clean Burning Wood Stoves and Fireplaces
"This site offers information to help you choose an EPA certified stove ... or another cleaner burning hearth appliance (e.g., gas or pellet stove) and use it efficiently and safely."Discusses stove and fireplace types, safe installation and wood-burning practices, impacts of wood smoke on human health and the environment, cleaner burning fireplace options, and related topics. Also includes a guide for implementing a wood stove change-out campaign. From the U.S. Environmental Protection Agency (EPA). COPD Not Just A Disease Of The Lungs
Chronic Obstructive Pulmonary Disease (COPD) can no longer be judged as only a disease of the lungs, say authors of an article in The Lancet. Researchers propose to add the term chronic systemic inflammatory syndrome to the diagnosis of COPD to reflect the frequent complex chronic comorbidities. The most common comorbidities associated with COPD are skeletal muscle abnormalities, high blood pressure, diabetes, coronary artery disease, heart failure, lung infections, cancer, and pulmonary vascular disease. The authors say: "Chronic comorbid diseases affect health outcomes in COPD; in fact patients with COPD mainly die of non-respiratory disorders such as cardiovascular disease or cancer." Obesity Finding: Chemical Pathway Causes Mice To Overeat And Gain Weig
Researchers from the Scripps Research Institute who are studying how body temperature and energy metabolism are regulated have discovered a pathway that appears to play a critical role in the onset of obesity. Further study of the pathway could lead to better understanding of the physiological foundation of obesity in humans and even the discovery of new treatments for the condition. Discarded Placentas Deliver Researchers Promising Cells Similar To Emb
Routinely discarded as medical waste, placentas could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cellsand available now as an early online publication in Stem Cells Express. Penn Study Points To How COX-2 Inhibitors Can Eventually Lead To Heart
University of Pennsylvania School of Medicine researchers have found additional evidence that may help explain how selective inhibitors of COX-2 might predispose individuals to heart disease and stroke. In Circulation Research, they report that a COX-2-derived fatty substance -- a prostaglandin called prostacyclin -- controls the blood-vessel response to stresses such as high-blood pressure, thereby further linking COX-2 inhibitors to an increased risk of heart attack or stroke. New Research Points Toward Mechanism Of Age-onset Toxicity Of Alzheime
Like most neurodegenerative diseases, Alzheimer's disease usually appears late in life, raising the question of whether it is a disastrous consequence of aging or if the toxic protein aggregates that cause the disease simply take a long time to form. Now, a new study shows that aging is what's critical. Harmful beta amyloid aggregates accumulate when aging impedes two molecular clean-up crews from getting rid of these toxic species. Labor Migration Played Key Role In HIV Spread In South Africa
South Africa has one of the world's highest rates of HIV infection. New research, led by Brown University professor Mark Lurie, shows that the movement of workers between urban and rural areas played a key role in the spread of the epidemic. Results are published in AIDS.
