Trigger of deadly food toxin discovered

A toxin produced by mold on nuts and grains can cause liver cancer if consumed in large quantities. UC Irvine researchers for the first time have discovered what triggers the toxin to form, which could lead to methods of limiting its production.

Why sex with a partner is better

OK, it takes two for human reproduction, and now it seems that plants and animals that can rely on either a partner or go alone by self-fertilization give their offspring a better chance for longer lives when they opt for a mate.

Widely used virus assay shown unreliable when compared to other methods

In the course of doing research on the mosquito-borne pathogens chikungunya virus and o' nyong-nyong virus, Virginia Tech researchers have discovered an inconvenient truth about an assay, strand-specific quantitative real-time PCR (ssqPCR), increasingly being used to detect and measure replicating viral RNA in infected cells and tissues. The method most labs are using for ssqPCR is unreliable.

Women Outperform Men When Identifying Emotions

Women are better than men at distinguishing between emotions, especially fear and disgust, according to a new study. Scientists demonstrated that women are better than men at processing auditory, visual and audiovisual emotions.

Women outperform men when identifying emotions

Women are better than men at distinguishing between emotions, especially fear and disgust, according to a new study published in the online version of the journal Neuropsychologia. As part of the investigation, Olivier Collignon and a team from the Université de Montréal Centre de recherche en neuropsychologie et cognition demonstrated that women are better than men at processing auditory,...

Women veterans less likely to report pain than male counterparts

In the first study to look at sex-specific pain prevalence in Operation Enduring Freedom/Operation Iraqi Freedom veterans, researchers from the VA Connecticut Healthcare System and the Yale University School of Medicine found women veterans had a lower prevalence of pain than male counterparts returning from the conflicts. Full details of the study appear in the October issue of Pain Medicine.

Could some forms of mental retardation be treated with drugs?

Growth factors. They are the proteins that trigger a countless number of actions in cells. Drugs that increase or decrease certain growth factors have lead to treatments for cancer and cardiovascular diseases. Georgetown University Medical Center researchers say a new understanding of a growth factor implicated in some mental retardation disorders could lead to a novel treatment.

Experimental treatments restore partial vision to blind people

Two experimental treatments, a retinal prosthesis and fetal tissue transplant, restored some vision to people with blinding eye diseases. The findings, presented at Neuroscience 2009, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health, may lead to new treatments for the blind. Researchers also reported that an engineered...

Sending Science Down The Phone: New Technology Will Map Research Across The World

New mobile phone software will help epidemiologists and ecologists working in the field to analyse their data remotely and map findings across the world, without having to return to the lab, according to research. The authors of the study say the software will also enable members of the public to act as 'citizen scientists' and help collect data for community...

IVF insurance coverage yields fewer multiple births, researchers find

The proportion of in vitro fertilization (IVF) multiple births was lower in the eight states that provide insurance coverage for couples seeking IVF treatment, primarily due to fewer embryos transferred per cycle, Yale School of Medicine researchers report in an abstract presented at the American Society for Reproductive Medicine meeting in Atlanta, Georgia, October 17-21.

Alzheimer's researchers find high protein diet shrinks brain

One of the many reasons to pick a low-calorie, low-fat diet rich in vegetables, fruits, and fish is that a host of epidemiological studies have suggested that such a diet may delay the onset or slow the progression of Alzheimer's disease (AD). Now a study published in BioMed Central's open access journal Molecular Neurodegeneration tests the effects of several diets, head-to-head, for their...
