Discovery of new gene associated with diabetes risk suggests link with body clock
A connection between the body clock and abnormalities in metabolism and diabetes has been suggested in new research by an international team.

Study associates 11 new gene sites with cholesterol, triglyceride levels
An international research team has identified 11 novel locations in the human genome where common variations appear to influence cholesterol or triglyceride levels, bringing the total number of lipid-associated genes to 30.

Body clock linked to diabetes and high blood sugar in new study
Diabetes and high levels of blood sugar may be linked to abnormalities in a person's body clock and sleep patterns, according to a genome-wide association study published today in the journal Nature Genetics.

Dismissed leukemia drug helps cll patients, studies show
A drug once dismissed as ineffective in patients with chronic lymphocytic leukemia has shown promising results in two phase I and II clinical trials, according to researchers at the Ohio State University Comprehensive Cancer Center -- James Cancer Hospital and Solove Research Institute.

Air pollution model takes off
Australia's capabilities in understanding the impact of air pollution have advanced with a new version of software that can predict the direction and concentration of odors and pollutants.

Biomarkers in blood could aid diagnosis of crippling, often fatal forms of malaria
Researchers with Canada's McLaughlin-Rotman Center for Global Health have identified protein biomarkers that may let doctors detect earlier two crippling malaria variations -- one that develops in the placenta of pregnant women affecting countless unborn children, the other, cerebral malaria, that develops in the brain's blood vessels -- malaria's most deadly form.

Genes for 9 health indicators
A new genome-wide study examines genetic variants associated with nine metabolic traits and is the first to draw out novel variants from a population unselected for current disease.

New record for information storage and retrieval lifetime advances quantum networks
Physicists have taken a significant step toward creation of quantum networks by establishing a new record for the length of time that quantum information can be stored in and retrieved from an ensemble of very cold atoms.

Rectal malaria drug could save many lives in rural Africa and Asia
A rectal application of the inexpensive antimalarial drug artesunate could save the lives of many people who develop severe malaria who live in the world's remotest locations, eg, rural Africa and Asia.

Mayo Clinic finds it generally safe to withdraw anti-seizure medication in children with epilepsy
A new Mayo Clinic study found that it is generally safe to withdraw anti-seizure medications in children with epilepsy who have achieved seizure-freedom while on the medication.

Southern Ocean resistant to changing winds
Intensifying winds in the Southern Ocean have had little influence on the strength of the Southern Ocean circulation and therefore its ability to absorb carbon dioxide from the atmosphere, according to a study published in Nature Geoscience.

Food can affect a cell in the same way hormones do
VIB researchers connected to the Katholieke Universiteit Leuven have discovered an important new mechanism with which cells can detect nutrients.

SIDS link: Low blood pressure in preterm infants
Scientists from Monash University, Melbourne have shown that infants born prematurely have lower blood pressure during sleep in the first six months of life, compared to healthy, full-term infants.

Alzheimer's disease breakthrough
CSIRO scientists have developed a new system to screen for compounds that can inhibit one of the processes that takes place during the progression of Alzheimer's disease.

Progression of retinal disease linked to cell starvation
A new study illuminates an incurable eye disease that afflicts approximately 100,000 Americans.

Older age doesn't affect survival after bone marrow transplant
Patients older than 65 do just as well as younger patients with transplants that are preceded by a milder chemotherapy regimen, reports the Center for International Blood and Marrow Transplant Research.

The genetic heart of the lipids
A new study presages a real aim of genetics: to look at whole populations in order to determine the significance of individual genetic variants for individual health.

Lenalidomide safe as single therapy for elderly CLL patients
The oral medication lenalidomide is safe and well-tolerated for elderly patients with chronic lymphocytic leukemia, a group without a well-defined frontline therapy for their disease, researchers from the University of Texas M.

Genome-wide association study to assess the risk of variant Creutzfeldt-Jakob disease
Although measures were taken to prevent further transmission to humans after the outbreak of variant Creutzfeldt-Jakob disease from infected cattle in the mid-1990s, the full extent of this outbreak and that of other prion diseases might not yet be realized.

New genes present drug targets for managing cholesterol and glucose levels
Scientists have identified 12 new genes that are somewhat strange bedfellows: Some link gallstones and blood cholesterol levels, others link melatonin and sleep patterns to small increases in glucose levels and larger jumps in the risk of diabetes.

Research on the effects of stem cell source and patient age on transplantation outcomes
Two studies examining the effects of stem cell source and patient age on stem cell transplantation outcomes will be explored at a press conference taking place on Sunday, Dec.

Research highlights new approaches to prevent blood clots
The largest study ever to examine the preventive use of blood-thinning medication to help prevent deadly blood clots in patients with cancer undergoing chemotherapy will be presented in a press conference on Sunday, Dec.

Nanotechnology 'culture war' possible, says Yale study
Rather than infer that nanotechnology is safe, members of the public who learn about this novel science tend to become sharply polarized along cultural lines, according to a study conducted by the Cultural Cognition Project at Yale Law School in collaboration with the Project on Emerging Nanotechnologies.

For nano, religion in US dictates a wary view
When it comes to the world of the very, very small -- nanotechnology -- Americans have a big problem: nano and its capacity to alter the fundamentals of nature, it seems, are failing the moral litmus test of religion.

'Strained' quantum dots show new optical properties
The first generation of quantum dots were made from the toxic heavy metal cadmium and had emission wavelengths, and colors, determined by their size.
