New analysis finds daycare attendance early in life cuts childhood leukemia risk by 30 percent
Children who attend day care or play groups have about a 30% lower risk of developing the most common type of childhood leukaemia than those who do not, according to a new analysis of studies investigating the link.

Analysis shows combining sorafenib with carboplatin/paclitaxel adds no benefit in lung cancer
A clinical trial evaluating the benefit of adding the drug sorafenib to the combination of carboplatin/paclitaxel chemotherapy for lung cancer patients has been stopped based on results from an interim analysis, after an independent data monitoring committee concluded that the study would not meet its primary endpoint of improved overall survival.

Yeast gives rise to new concept: cell fuel is 'brains' behind division
With the cost of diesel and gasoline getting nearer to the hourly minimum wage, too bad the fuel doesn't do more work - like deciding what route to take and pressing the gas pedal.

High self-esteem is not always what it's cracked up to be, says UGA psychologist
Oscar Levant, a mid-century pianist, film star and wit, once watched noted keyboardist and composer George Gershwin spend an evening playing his own music at a party and clearly having a great time.

Emissions irrelevant to future climate change?
Climate change and the carbon emissions seem inextricably linked. However, new research published in BioMed Central's open access journal Carbon Balance and Management suggests that this may not always hold true, although it may be some time before we reach this saturation point.

Carnegie Mellon researchers urge development of low carbon electricity
Carnegie Mellon University's Constantine Samaras and Kyle Meisterling report that plug-in hybrid electric vehicles could help reduce greenhouse gas emissions that fuel global warming, but the benefits are highly dependent on how the electricity system changes in the coming decades.

Study links low-frequency hearing to shape of the cochlea
Shape matters, even in hearing. Specifically, it is the shape of the cochlea - the snail-shell-shaped organ in the inner ear that converts sound waves into nerve impulses that the brain deciphers - which proves to be surprisingly important.

Different Processes Govern Sight, Light Detection
A Johns Hopkins University biologist, in research with implications for people suffering from seasonal affective disorder and insomnia, has determined that the eye uses light to reset the biological clock through a mechanism separate from the ability to see.

Study shows common vitamin and other micronutrient supplements reduce risks of TB recurrence
New findings show a link between micronutrient supplementation and reduced risk of recurrence during tuberculosis chemotherapy, according to a study published in the June 1 issue of The Journal of Infectious Diseases, now available online.

Anesthesia and Alzheimer's
In studies of human brain cells, the widely-used anesthetic desflurane does not contribute to increased production of amyloid-beta protein; however, when combined with low oxygen conditions, it can produce more of this Alzheimer's associated protein.

Exeter engineers create new technique for malaria diagnosis
Researchers from the Universities of Exeter and Coventry have developed the first new technique for diagnosing malaria able to challenge the rapid diagnostic tests (RDTs) currently used in the field.

Autistic mannerisms reduced by sensory treatment
Parents of children with autism are increasingly turning to sensory integration treatment to help their children deal with the disorder, and they're seeing good results.

Surprising language abilities in children with autism
What began as an informal presentation by a clinical linguist to a group of philosophers, has led to some surprising discoveries about the communicative language abilities of people with autism.

Researchers important markers of high risk of type 2 diabetes.
Doctors are aware of a range of risk factors, mostly related to the patients' family history, overweight, and lifestyle, that contribute to the risk of developing type 2 diabetes.

Study shows false memories complicate end-of-life treatment decisions
Advance directives, or living wills, may not effectively honor end-of-life wishes because life-sustaining treatment preferences often change over time without people being aware of the changes, according to a new study co-authored by UC Irvine researchers Peter Ditto and Elizabeth Loftus.

Epigenetic research uncovers new targets for modification enzymes
Enzymes regulating genetic expression can be just as important as the genome itself, increasing evidence shows. The expanding field of epigenetics focuses on the multiple influences on DNA and surrounding molecules that determine whether genes are turned on or off during development and disease processes.

Looking at neurons from all sides
A new technique that marries a fast-moving laser beam with a special microscope that look at tissues in different optical planes will enable scientists to get a three-dimensional view of neurons or nerve cells as they interact, said Baylor College of Medicine scientists in a report that appears today in the journal Nature Neuroscience.

Study finds that minimally invasive robotic bypass surgery provides health and economic benefits
Minimally invasive heart bypass surgery using a DaVinci robot means a shorter hospital stay and faster recovery for patients, as well as fewer complications and a better chance that the new bypass vessels will stay open.
