Gene guards grain-producing grasses so people and animals can eat
02-01-2008 · EurekAlert!Purdue University and USDA-Agricultural Research Service scientists have discovered that a type of gene in grain-producing plants halts infection by a disease-causing fungus that can destroy crops vital for human food supplies.

- One shot of gene therapy spreads through brain in animal study
10-08-2007 · EurekAlert!
By targeting a site in a mouse brain well connected to other areas, researchers successfully delivered a beneficial gene to the entire brain—after one injection of gene therapy. If these results in animals can be realized in people, researchers may have a potential method for gene therapy to treat a host of rare but devastating congenital human neurological disorders, such as Tay-Sachs disease.

- Microbes compete with animals for food by making it stink
11-01-2006 · EurekAlert!
Microbes may compete with large animal scavengers by producing repugnant chemicals that deter higher species from consuming valuable food resources, a new study suggests.Ecologists have long recognized microbes as decomposers and pathogens in ecological communities. But their role as classic consumers who produce chemicals to compete with larger animals could be an important and common interaction within many ecosystems, according to a paper published this week in the journal Ecology.

- Mixed prairie grasses are better biofuel source, U of M study says
12-07-2006 · EurekAlert!
Highly diverse mixtures of native prairie plant species have emerged as a leader in the quest to identify the best source of biomass for producing sustainable, bio-based fuel to replace petroleum. A new study led by David Tilman, Regents Professor of Ecology in the University of Minnesota's College of Biological Sciences, shows that mixtures of native perennial grasses and other flowering plants provide more usable energy per acre than corn grain ethanol or soybean biodiesel and are far better for the environment.

- New technique to 'see' and protect transplants successful in diabetic animal model
07-29-2007 · EurekAlert!
Researchers at Johns Hopkins have found a way to overcome a major stumbling block to developing successful insulin-cell transplants for people with type I diabetes. They developed a new technique encapsulates the insulin-producing cells in magnetic capsules, using an FDA-approved iron compound with an off-label use, which can be tracked by magnetic resonance imaging (MRI). The product, tested in swine and diabetic mice, also simultaneously avoids rejection by the immune system, likely a major reason for transplant failure.

- UCF student's research with Disney giraffes may help conserve several species
01-29-2007 · EurekAlert!
University of Central Florida doctoral student Jennifer Fewster is studying giraffe poop at Disney's Animal Kingdom Lodge in Lake Buena Vista in an effort to figure out what the animals eat in the wild and to improve the nutrition of those in captivity. Results from they study may also help protect other herbivores in the wild.

- Researchers use magnetism to target cells to animal arteries
01-07-2008 · EurekAlert!
Scientists have used magnetic fields and tiny iron-bearing particles to drive healthy cells to targeted sites in blood vessels. The research, done in animals, may lead to a new method of delivering cells and genes to repair injured or diseased organs in people.

- Jefferson scientists uncover gene mutation that cuts colon polyps, may suppress cancer
03-21-2007 · EurekAlert!
Scientists have found a gene mutation that can dramatically reduce the number of colon polyps that develop, potentially cutting the risk of cancer. Researchers studying mice prone to develop polyps discovered that animals carrying the damaged gene had about 90 percent fewer polyps in the small intestine and colon. Because people with large numbers of polyps are at higher risk for colon cancer, the finding may provide new ways to diagnose, prevent and treat it.

- Pharmaceutical breakthrough may make a range of drugs cheaper and more available
01-31-2008 · EurekAlert!
A new study published in the February 2008 print edition of The FASEB Journal describes an advance that should reduce the cost and increase the availability of several drugs. University of Pennsylvania researchers used gene therapy to breed large animals capable of producing therapeutic proteins in their milk, such as insulin or those that fight cancer. This represents a significant milestone, as previous methods involved cloning, which takes more time and generally costs more.

- Food-mood connection: The sad are twice as likely to eat comfort food
01-31-2007 · EurekAlert!
People feeling sad tend to eat more of less-healthy comfort foods than when they feel happy, finds a new study co-authored by Cornell's Brian Wansink. However, when nutritional information is available, those same sad people curb their hedonistic consumption, but happier people don't.
