Iowa State University experts can discuss new FDA produce irradiation rule
The Food and Drug Administration's new (Aug. 22) regulation that will allow irradiation pasteurization to be used on fresh spinach and iceberg lettuce to kill illness-causing bacteria is a step that two Iowa State University professors have long advocated. view more (2008-08-25)
Red kiwi poised to make a healthy debut
First there was green, then yellow and now red-fleshed kiwifruit. A team of researchers in Italy and New Zealand has found that a newly developed variety of red-fleshed kiwifruit contain anthocyanins, bright red pigments that are highly potent antioxidants. view more (2005-11-10)
Zinc oxide gives green shine to new photoconductors
Photodetectors -- devices found in cell phones, digital cameras and other consumer gadgets that utilize photoconducting materials -- are a green technology in performance (converting light into electricity), but the manufacture of very powerful photodetectors needs to be improved before they can qualify for solid green status. view more (2009-03-19)
Pitt team finds molecule that regulates heart size by using zebrafish screening model
Using zebrafish, researchers at the University of Pittsburgh have identified and described an enzyme inhibitor that allows them to increase the number of cardiac progenitor cells and therefore influence the size of the developing heart. view more (2009-07-06)
New findings about brain proteins suggest possible way to fight Alzheimer's
The action of a small protein that is a major villain in Alzheimer's disease can be counterbalanced with another brain protein, researchers at UT Southwestern Medical Center have found in an animal study. view more (2009-10-07)
New GM mosquito sexing technique is step towards malaria control, report scientists
Scientists have genetically modified male mosquitoes to express a glowing protein in their gonads, in an advance that allows them to separate the different sexes quickly. view more (2005-10-10)
Flu can bide time in icy limbo before re-emerging
It sounds like a campy '50s horror movie ("It Came from the Ice!"), but a Bowling Green State University biologist believes it's a very real possibility. Dr. Scott Rogers is talking about the potential for long-dormant strains of influenza, packed in ice in remote global outposts, to be unleashed by melting and migratory birds. view more (2006-11-29)
Tissue regeneration operates differently than expected
Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim, Germany, in co-operation with colleagues from Martin Luther University in Halle-Wittenberg, have now shown that skeletal muscle tissue can fuse with adult stem cells, via a mechanism based on the participation of mediators which are generally involved in immune... view more...

Researchers identify taste receptor responsible for caffeine detection
By studying how taste-receptor mutations impact fruit fly behavior, researchers have identified a taste receptor responsible for the detection of caffeine, a bitter compound known to activate certain taste-receptor neurons, as well as impact various aspects of physiology. view more (2006-09-19)
Light-protection for food packaging
Oxygen and light can alter the taste of foodstuffs. Manufacturers of packaging materials therefore try to protect contents from their influence. The latest approach is to use natural dyes in transparent plastic wrappers that selectively filter light. view more (2002-02-01)
Naturally-occurring apple compounds reduce risk of pancreatic cancer
Eating flavonol-rich foods like apples may help reduce the risk of pancreatic cancer, says a team of international researchers. Quercetin, which is found naturally in apples and onions, has been identified as one of the most beneficial flavonols in preventing and reducing the risk of pancreatic cancer. view more (2007-10-04)
NASA's Chandra finds black holes are 'green'
Black holes are the most fuel efficient engines in the Universe, according to a new study using NASA's Chandra X-ray Observatory. view more (2006-04-25)
NIH-funded researchers transform embryonic stem cells into human germ cells
Researchers funded in part by the National Institutes of Health have discovered how to transform human embryonic stem cells into germ cells, the embryonic cells that ultimately give rise to sperm and eggs. view more (2009-10-29)
Reducing caffeine intake has no effect on birth weight or length of pregnancy
There is no evidence that moderate levels of caffeine consumption during pregnancy lead to a greater risk of premature births and underweight babies despite warnings from some public health officials. view more (2007-01-29)
Genetically engineered bacteria compute the route
US researchers have created 'bacterial computers' with the potential to solve complicated mathematics problems. view more (2009-07-24)
It's your funeral: The eco burial movement gathers ground
Natural burial is often thought of as a green option that takes place in the countryside for non-religious people, but according to researchers at the University of Sheffield, that is only part of the story. view more (2009-03-09)
Good breeding increases shelf life
The lettuce cut and packaged for food service and salad mixes is an increasingly important component of the produce industry. Lettuce is highly perishable, and the cutting required in processing further shortens its shelf life. view more (2008-07-21)
Despite Britain's weather, the sun always shines on PV
Contrary to popular opinion, Britain's weather is suited to solar power, say researchers at the University of Oxford. In an independent test of the leading types of solar photovoltaic (PV) panels, they are finding out which types of solar panels work best in Britain's often dull and varied climate. Solar photovoltaic (PVs) are one of the most... view more... (2001-05-24)
Lone dieters have slim chance of success
Organised weight loss groups are the most effective way to diet, according to new research conducted by Aston University's Dr Mike Green and Nicola Elliman in conjunction with the Western Human Nutrition Center, University of California. The study (funded by the US Department of Agriculture) measured the... view more... (2004-02-25)
Sperm stem cells closer to being like embryonic stem cells
New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body. view more (2005-11-16)
