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.

A study published tomorrow in JAMA by Nancy M. Albert and colleagues, exploring aldosterone antagonist usage among US patients hospitalized with heart failure, found that only one-third of patients meeting current US Clinical Practice Guidelines criteria were actually being treated.

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.

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 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 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,...

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.

HealthDay - TUESDAY, Oct. 20 (HealthDay News) -- People with cardiovascular conditions such as heart failure and stroke -- and probably their close relatives as well -- may have an increased risk for hip fractures, a new study has found.

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.

Scientists identify a new and elusive species of "giant" golden orb-weaving spider which is the biggest of its group.

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...

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...

A study that includes twins finds that the risk of hip fracture was significantly increased following a diagnosis of cardiovascular disease (CVD), with analysis also suggesting a genetic predisposition to the development of CVD and fractures, according to a study in the October 21 issue of JAMA.

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.

Logged rainforests can support as much plant, animal and insect life as virgin forest within 15 years if properly managed, new research has found.

Children who receive a three-day course of antibiotics following tonsillectomy rather than a seven-day course appear to have no differences in pain or how quickly they return to a normal diet and activity level, according to a new report.

AP - Three South American nations announced a joint plan Tuesday to establish protected zones in the vast Atlantic Forest as part of an effort to halt deforestation by 2020.

Reuters - The world needs genetically modified crops both to increase food yields and minimize the environmental impact of farming, Britain's top science academy said on Wednesday.

Scotland's populations of a bird of prey hunted to extinction by the Victorians are in their healthiest state for 150 years.

The UK should plough £2bn into food research to help stave off world hunger, says the Royal Society.

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...
