Scientist discovers mechanism that 'silences' unmatched genes during cellular reproduction

When most people discover mold on their bread, they immediately throw it out. Others see a world of possibilities in the tiny fungus. A University of Missouri scientist, along with a collaborative research team, has examined a new mechanism in the reproductive cycle of a certain species of mold.

New key mechanism in cell division discovered

Scientists at the IFOM-IEO Campus have revealed the function of a protein that is indispensable for passing on an accurate copy of the genome from mother to daughter cells. This study, published in Cell, opens up new avenues of research to reduce the toxicity of chemotherapy in the treatment of cancer.

Nanoworms developed to target tumors

Scientists at UC San Diego, UC Santa Barbara and MIT have developed nanometer-sized "nanoworms" that can cruise through the bloodstream without significant interference from the body's immune defense system and-like tiny anti-cancer missiles-home in on tumors.

Most comprehensive kinome collection

Scientists from University of Helsinki, Institute of Molecular Medicine in Finland and OriGene Technologies joined effort in creating the most comprehensive kinome collection of nearly all predicted human protein kinases, including the functional kinases and their kinase-deficient counterparts. Equipped with this collection, the authors successfully identified novel kinase regulators in Hedgehog signaling pathway and in activation of Karposi's Sarcoma herpesvirus.

Whole-organ genomic survey depicts journey from normal to malignant cell

Whole-organ maps that superimpose genetic information over the terrain of cancerous bladders chart the molecular journey from normal cell to invasive cancer, an international research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports online at the journal Laboratory Investigation.

Scientists produce stem cells from ordinary mouse skin cells

Researchers in the United States say they have produced a stem cell made from ordinary mouse skin cells which they have coaxed into becoming three different types of heart and blood cells in mice.

Males and females have essentially unisex brains - at least in flies!

Research by Yale scientists shows that males and females have essentially unisex brains - at least in flies - according to a recent report in Cell designed to identify factors that are responsible for sex differences in behavior.

Silent fungus metabolism awakened for source of new drugs

U.S. scientists have re-awakened 'silent' metabolic pathways in fungi to reveal a new range of natural products. The research could provide not only a source of new drugs, but a way to "listen to what fungi are saying" to organisms around them.

First sequence-based map of large-scale structural variation across the human genome

A nationwide team of researchers, funded in part by the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), has produced the first sequence-based map of large-scale structural variation across the human genome. The work, published today in the journal Nature, provides a starting point to examine how such DNA variation contributes to human health and disease.

Binge eating and crash diets could shorten your life

According to scientists in Britain binge eating and crash dieting may significantly reduce life expectancy.

New findings challenge conventional ideas on evolution of human diet, natural selection

New findings suggest that the ancient human "cousin" known as the "Nutcracker Man" wasn't regularly eating anything like nuts after all.

Miniscule closed containers for precise delivery of nano-quantities of drugs

Researchers at the USC Information Sciences Institute have demonstrated a way to manufacture miniscule closed containers that might be used to deliver precise micro- or even nano-quantities of drugs.

Silver nanoparticles may kill beneficial bacteria

Too much of a good thing could be harmful to the environment. For years, scientists have known about silver's ability to kill harmful bacteria and, recently, have used this knowledge to create consumer products containing silver nanoparticles.

CSIRO researchers open up new class of chemistry

CSIRO Entomology business manager, Cameron Begley, said researchers believed the discovery opened up an entirely new class of chemistry.

Scientists determine drug target for the most potent botulinum neurotoxin

Botulinum neurotoxin - responsible for the deadly food poisoning disease botulism and for the beneficial effects of smoothing out facial wrinkles - can also be used as a dreaded biological weapon. When ingested or inhaled, less than a billionth of an ounce can cause muscle paralysis and eventual death. Although experimental vaccines administered prior to exposure can inhibit the destructive action of this neurotoxin - the most deadly protein known to humans - no effective pharmacological treatment exists.

New research suggests hypertonic, hyperviscous fluids may be better treatment for severe blood loss

Intravenous administration of isotonic fluids is the standard emergency treatment in the U.S. for patients with severe blood loss, but UC San Diego bioengineering researchers have reported improved resuscitation with a radically different approach. Building on earlier studies in humans that have shown benefits of intravenous fluids that are eight times saltier than normal saline, the researchers combined hypertonic saline with viscosity enhancers that thicken blood.

Scientists find distinct kind of stem cells in the pituitary gland

A team of researchers led by scientists at Cold Spring Harbor Laboratory have for the first time identified stem cells that allow the pituitary glands of mice to grow even after birth.
