New toxicity test could cut animal testing
To test whether chemicals are toxic to humans, researchers need to use liver cells that have been freshly harvested from mice or other mammals. A new collection of stable cell lines, described in BMC Biotechnology this week, could reduce the numbers of animals needed in such experiments. The MMH-GH... view more (2004-03-17)

Stopping the clock: Genetics of tumor latency in skin cancer
Dr. Anthony E. Oro and colleagues (Stanford University) have identified two key Gli protein degradation signals that directly affect tumor latency in a mouse model of human skin cancer.   view more (2006-01-20)

Poorer farmers benefit most from organic practices
Farmers in developing countries are reaping the benefits of adopting 'green' agricultural practices far more than their western counterparts, suggests a report published today, Thursday 14 February 2002. The report by Nicolas Parrott at Cardiff University's Department of City and Regional Planning... view more (2002-02-12)

Intake of dietary copper helps Alzheimer's patients
As one of the services for patients with Alzheimer's disease, the Department of Psychiatry at the Saarland University Medical Center offers participation in a clinical phase II trial. This clinical trial aims to elucidate a potential beneficial effect of copper orotate (an organic copper salt),... view more (2005-10-04)

Eating and body weight regulated by specific neurons
Researchers at Yale School of Medicine provide direct evidence that two parts of a neuronal system, one that promotes eating and another that suppresses eating, are critical for the acute regulation of eating and body weight.   view more (2005-09-14)

Central and peripheral signals set the circadian liver clock
Anyone who has experienced jet lag will understand the importance of a smooth-running circadian clock. Crossing time zones decouples our biological rhythms from the natural cycle of light and dark we're used to.   view more (2007-01-30)

Destruction of a GM barley research trial at the John Innes Centre
Over the weekend of 15-17th June 2001 a small research plot of genetically modified (GM) barley plants at the John Innes Centre*, Norwich (JIC), was destroyed by trespassers. "This trial was part of a publicly funded programme to provide important information to the UK Food Standards Agency" said... view more (2001-06-25)

Colon Cancer : An alternative pathway of tumor development
Cancer develops from a single damaged cell subsequent to an accumulation of genetic errors in a number of its genes. The nature of these alterations and the order in which they occur differ from one cancer to another : hence, the "pathways" that may lead to cancer are numerous. CNRS and... view more (2002-09-13)

Researchers develop first transgenic monkey model of Huntington's disease
Scientists have developed the first genetically altered monkey model that replicates some symptoms observed in patients with Huntington's disease, according to a new study funded by the National Institutes of Health.   view more (2008-05-19)

New DNA 'fingerprinting' technique separates hemp from marijuana
Using new DNA "fingerprinting" techniques, two University of Minnesota researchers have become the first to unequivocally separate hemp plants from marijuana plants with genetic markers.   view more (2006-03-23)

Interferon-treated hepatitis C patients likely to experience retinopathy
Persons with chronic hepatitis C being treated with Interferon (IFN) are at risk of developing retinopathy as early as two weeks into treatment according to the results of a new study published in the January 2007 issue of Investigative Ophthalmology & Visual Science (IOVS).   view more (2007-01-04)

Simulated crop provides answer to irrigation issues
South Asia has witnessed a rapid growth in rice and wheat production that has defined the Green Revolution there. During the past 30 years, the Indian Punjab has transformed its agriculture through new technology that provides for high-producing plants, increased fertilization, and irrigation.   view more (2007-07-13)

Biorefining of corn brings gelatin production into the 21st century
Scientists are reporting an advance toward turning corn plants into natural factories for producing gelatin to replace animal-sourced gelatin widely used by the pharmaceutical industry for manufacturing capsules and tablets.   view more (2007-08-23)

New advances may slow tumor growth in pancreatic cancer
Making new strides in their ongoing effort to understand mechanisms behind the relentless growth of cancer cells, researchers at Dartmouth Medical School have found a promising key that may open doors to future treatments in pancreatic and other forms of cancer   view more (2005-06-10)

Plants that produce more vitamin C may result from UCLA-Dartmouth discovery
UCLA and Dartmouth scientists have identified a crucial enzyme in plant vitamin C synthesis, which could lead to enhanced crops. The discovery now makes clear the entire 10-step process by which plants convert glucose into vitamin C, an important antioxidant in nature.   view more (2007-05-24)

Ionophore reverses Alzheimer's within days in mouse models
Scientists report a remarkable improvement in Alzheimer's transgenic mice following treatment with a new drug. The study, published by Cell Press in the July 10th issue of the journal Neuron, provides the first demonstration that an ionophore, a compound that transports metal ions across cell... view more (2008-07-10)

Hotter is better for removing allergens in laundry

Filter That Makes Viruses Adhere
Siberian researchers have developed a biologically active sorbent of a new generation. The sorbent provides for the 100-percent efficient water purification from microorganisms and bacteriophages. Microbiological researches were performed with partial support of the U.S. Civilian Research and... view more (2005-03-25)

In scientific first, Einstein researchers correct decline in organ function associated with old age
As people age, their cells become less efficient at getting rid of damaged protein - resulting in a buildup of toxic material that is especially pronounced in Alzheimer's, Parkinson's disease, and other neurodegenerative disorders.   view more (2008-08-11)

ETH Zurich plans field trials using transgenic wheat
ETH Zurich plans to conduct field trials with transgenic wheat this year. Though the Swiss Federal Department of Environment, Transport, Energy and Communications (DETEC) has rejected the appeal against the approval of the trials, the decision can still be challenged in the Federal Supreme Court.... view more (2004-03-04)
