Home / Blogs / Science & the Public / Science & the Public : EPA rejects climate-change deniers’ petitionsA number of people challenge that climate change is real, that it's due to greenhouse gases released by human activities and that it's a threat to human health and the environment. On July 29, the Environmental Protection Agency formally rejected those claims as it turned down 10 petitions asking the Obama administration to reconsider EPA’s “endangerment finding.”Published: Thursday, July 29th, 2010Found in: Climate Change, Environment and Science & Society

Home / Blogs / Science & the Public / Science & the Public : More evidence that BPA laces store receiptsPeople interested in limiting exposure to bisphenol A — a hormone-mimicking environmental contaminant — might want to consider wearing gloves the next time a store clerk hands over a cash-register receipt. A July 27 report by a public-interest research group has now confirmed many of these receipts have a BPA-rich powdery residue on their surface.Published: Tuesday, July 27th, 2010Found in: Chemistry, Environment, Molecules, Science & Society and Technology -
Astronauts may have to survive in orbit for months dining on a really limited menu of processed foods and reconstituted beverages served from oh-so-glamorous plastic pouches. Luckily, even the International Space Station can restock its pantry several times a year because these foods are relatively perishable. Which explains the problem NASA faces in planning for really long missions — like a trip to Mars.Published: Monday, July 26th, 2010 -
Home / Blogs / Science & the Public / Science & the Public : Coffee perks up memory and balance in geriatric animalsMillions of Americans start their day with a cup of coffee and then reach for refills when their energy or attention flags. But new research in rats suggests that for the aging brain, coffee may serve as more than a mere stimulant. It can boost memory and the signaling essential to motor coordination.Published: Thursday, July 22nd, 2010Found in: Body & Brain, Chemistry, Food Science, Nutrition and Science & Society

Home / Blogs / Science & the Public / Science & the Public : Good vibrations: A greener way to pasteurize milkMany people like the taste of raw – as in unpasteurized – milk. The problem, of course, is that germs may infect raw milk, so food safety regulations require that commercial producers heat-treat their milk. But food scientists at Louisiana State University think they’ve stumbled onto a tastier way to sterilize milk. They bombard it with sound waves.Published: Wednesday, July 21st, 2010Found in: Food Science, Matter & Energy, Molecules, Science & Society and Technology

Home / Blogs / Science & the Public / Science & the Public : Nano-scale additives fight food pathogensNano products are all the rage, even in food science. Here at the Institute of Food Technologists’ annual meeting, on July 18, scientists described dramatic success in fighting food-poisoning bacteria by doctoring foods or their packaging with microbe-killing nanoparticles – sometimes along with natural anti-bacterial agents.Published: Tuesday, July 20th, 2010Found in: Biomedicine, Food Science, Science & Society and Technology

Adding viruses to foods doesn’t sound appetizing, much less healthy. But it’s a stratagem being explored to knock some of the more virulent food poisoning bacteria out of the U.S. food supply. Scientists described data supporting the tactic July 18 at the Institute of Food Technologists’ annual meeting in Chicago.Published: Monday, July 19th, 2010Found in: Agriculture, Biomedicine, Food Science and Science & Society

The next generation of solar cells will be small. About the size of lint. But the anticipated impact: That’s huge. Some of these emerging electricity-generating cells could be embedded in windows without obscuring the view. Engineers envision incorporating slightly larger ones into resins that would be molded onto the tops of cars or maybe the roofs of buildings. One team of materials scientists is developing microcells that could be rubber-stamped by the millions onto a yard of fabric. When such cells shrink in size — but not efficiency — it becomes hard to imagine what they couldn’... (p. 28)Published: July 31st, 2010; Vol.178 #3 -

Home / Blogs / Science & the Public / Science & the Public : Fructose sweeteners may hike blood pressureThe more fructose American adults add to their diets, the higher their blood pressure tends to be. The new finding adds fuel to a simmering controversy about whether this simple sugar — found in fruits, table sugar, soft drinks and many baked goods — poses a health hazard that goes beyond simply consuming too many empty calories.Published: Friday, July 2nd, 2010Found in: Biomedicine, Food Science, Nutrition and Science & Society -
Home / Blogs / Science & the Public / Science & the Public : Breast screening tool finds many missed cancersA relatively new imaging option outperforms all comers in scouting for hidden breast tumors. Indeed, argues radiologist Rachel Brem, her team’s new data indicate that that “almost 10 percent of women with breast cancer have another [tumor] that we wouldn’t know about without this technology.”Published: Thursday, July 1st, 2010Found in: Biomedicine, Science & Society and Technology -
Home / Blogs / Science & the Public / Science & the Public : Ivy nanoparticles promise sunblocks and other green productsI’ve developed a love-hate relationship with English ivy that’s been devolving towards hate-hate. But a new paper may temper my antipathy. Apparently this backyard bully also offers a kinder, gentler alternative to the potentially toxic metal-based nanoparticles used in today’s sunscreens.Published: Tuesday, June 29th, 2010Found in: Biomedicine, Botany, Environment, Molecules, Science & Society and Technology -
Home / Blogs / Science & the Public / Science & the Public : How resveratrol (in grapes, peanuts and wine) fights fat and diseaseResveratrol, a constituent of grapes and certain other plants, can fight the proliferation of fat cells and improve the uptake of sugar from the blood, a pair of new studies indicate. These observations offer some mechanisms to explain why grape products, including wine, have developed a reputation as heart healthy, obesity-fighting and beneficial for people developing diabetes.Published: Wednesday, June 23rd, 2010Found in: Biomedicine, Food Science, Nutrition and Science & Society

Home / Blogs / Science & the Public / Science & the Public : Abuse of pharmaceuticals is rising sharplyIn 2008, the most recent year for which data are available, an estimated 1 million Americans entered a hospital emergency room for treatment of an overdose due to “nonmedical” use of an over-the-counter or prescription drug. That’s double the number of such visits five years earlier, federal data show.Published: Tuesday, June 22nd, 2010Found in: Biomedicine, Body & Brain and Science & Society
