Of hurricanes, fungus and Parkinson's disease Posted: 11 Nov 2013 01:14 PM PST Researchers trying to understand the link between volatile organics and illness discovered a link between one such compound and Parkinson's-like symptoms.

Biosensor could help detect brain injuries during heart surgery Posted: 11 Nov 2013 11:41 AM PST Engineers and cardiology experts have teamed up to develop a fingernail-sized biosensor that could alert doctors when serious brain injury occurs during heart surgery.

Nurture impacts nature: Experiences leave genetic mark on brain, behavior Posted: 11 Nov 2013 10:14 AM PST New human and animal research released demonstrates how experiences impact genes that influence behavior and health. New insights have been made into how experience might produce long-term brain changes in behaviors like drug addiction and memory formation.

Gene speeds kidney disease progression, failure in blacks, regardless of diabetes status Posted: 11 Nov 2013 09:21 AM PST A large study found that African Americans with the APOL1 gene variant experience faster progression of chronic kidney disease and have a significantly increased risk of kidney failure, regardless of their diabetes status.

Some 'healthy' vegetable oils may actually increase risk of heart disease Posted: 11 Nov 2013 09:21 AM PST Some vegetable oils that claim to be healthy may actually increase the risk of heart disease, and health officials should reconsider cholesterol-lowering claims on food labelling, states an analysis.

Key link responsible for colon cancer initiation, metastasis Posted: 11 Nov 2013 09:21 AM PST An research team has shown that a key genetic culprit, called CXCR2, is implicated in the tumor formation, growth and progression in a mouse model of colon cancer.

Nanotech drug smugglers Posted: 11 Nov 2013 08:25 AM PST Tiny capsules of carbon are invisible to the chemical gatekeeper that flushes potentially harmful substances out of our bodies' cells, according to new research. The finding might allow a pharmaceutical to be smuggled into cells even when multidrug resistance has evolved.

Hospitals Vary in Monitoring, Treatment of Children with Brain Injury Posted: 11 Nov 2013 08:25 AM PST Hospitals vary in management of children with traumatic brain injury, particularly in monitoring and preventing the harmful effects of increased intracranial pressure (ICP), according to a study.

Molecular interplay explains many immunodeficiencies Posted: 11 Nov 2013 07:25 AM PST Scientists have described an exquisitely balanced interplay of four molecules that trigger and govern antibody production in immune cells. As well as being an important basic science discovery, it helps explain why people with mutations in any one of the associated genes cannot fight infection effectively, and develop rare and crippling immunodeficiency disorders.

Discovery may lead to new treatments for allergic diseases Posted: 11 Nov 2013 07:25 AM PST A collaboration among researchers in Israel and the United States has resulted in the discovery of a new pathway with broad implications for treating allergic diseases -- particularly eosinophil-associated disorders. Researchers have discovered how this pathway kills eosinophils before they can cause havoc. Eosinophils are normal cellular blood components, but when the body produces too many eosinophils they can cause a variety of eosinophilic disorders.

Understanding immune system memory -- in a roundabout way Posted: 11 Nov 2013 07:24 AM PST While the principle of immune memory has been known for decades, the exact molecular mechanisms underpinning it have remained a mystery. Scientists have now unraveled part of that mystery, identifying the role of a gene called STAT3, which acts as a kind of roundabout, directing chemical messenger molecules to various destinations.

Geeks, jocks and shocks: Student perceptions of high-achieving classmates Posted: 11 Nov 2013 07:22 AM PST Imagine a new student is to join your class. The only thing you know about them is that they were the best in their previous class for the following subject…

New FDA proposal trying to eliminate trans fat Posted: 11 Nov 2013 07:20 AM PST Experts support the recent FDA proposal to eliminate trans fat from the food supply.

Brainstem abnormalities found in SIDS infants, in all sleep environments Posted: 11 Nov 2013 06:17 AM PST Investigators report that infants dying suddenly and unexpectedly, in both safe and unsafe sleep environments, have underlying brainstem abnormalities and are not all normal prior to death.

Poor, young breast cancer patients may experience delays in seeking care Posted: 11 Nov 2013 06:17 AM PST Researchers who sought to determine why breast cancers are more deadly in young women found that only a minority of young women experience long delays between the time they detect a breast abnormality and the time they receive a diagnosis, but delays in seeking care are more common in women with fewer financial resources.

Multiple birth pregnancies can cost 20 times more than singletons Posted: 11 Nov 2013 06:15 AM PST As multiple birth pregnancies can cost nearly 20 times more than singleton pregnancies, strategies to minimize multiple embryo transfer should be considered, researchers argue.

What are you scared of? Posted: 11 Nov 2013 06:13 AM PST What do bullies and sex have in common? Based on work by scientists, it seems that the same part of the brain reacts to both. The researchers found that – at least in mice – different types of fear are processed by different groups of neurons, even if the animals act out those fears in the same way. The findings could have implications for addressing phobias and panic attacks in humans.

How zinc starves lethal bacteria to stop infection Posted: 11 Nov 2013 06:11 AM PST Researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.

Fast-mutating DNA sequences shape early development; Guided evolution of uniquely human traits Posted: 10 Nov 2013 05:44 PM PST What does it mean to be human? According to scientists the key lies, ultimately, in the billions of lines of genetic code that comprise the human genome. The problem, however, has been deciphering that code. But now, researchers have discovered how the activation of specific stretches of DNA control the development of uniquely human characteristics -- and tell an intriguing story about the evolution of our species.

Exercise during pregnancy gives newborn brain development head start Posted: 10 Nov 2013 05:43 PM PST As little as 20 minutes of moderate exercise three times per week during pregnancy enhances the newborn child's brain development, according to researchers. This head-start could have an impact on the child's entire life.

Cause of genetic disorder found in 'dark matter' of DNA Posted: 10 Nov 2013 03:44 PM PST Pancreatic agenesis results in babies being born without a pancreas, leaving them with a lifetime of diabetes and problems digesting food. In a breakthrough for genetic research, scientists found that the condition is most commonly caused by mutations in a newly identified gene regulatory element in a remote part of the genome, which can now be explored thanks to advances in genetic sequencing.

Racial difference in blood clotting warrants closer look at heart attack medications Posted: 10 Nov 2013 03:44 PM PST Blood clot formation follows a different molecular route in African-Americans versus European-Americans, providing a new understanding of the effects of race on heart disease. The finding could one day help doctors provide more individualized treatment of heart disease and other blood-clot-related illnesses.

Single-cell genome sequencing gets better Posted: 10 Nov 2013 03:44 PM PST Researchers have generated the most complete genome sequences from single E. coli cells and individual neurons from the human brain. Preliminary data suggest that individual neurons from the same brain have different genetic compositions. The breakthrough comes from a new single-cell genome sequencing technique that confines genome amplification to fluid-filled wells with a volume of just 12 nanoliters.

Teens with late bedtimes have lower grades Posted: 10 Nov 2013 03:43 PM PST Late bedtimes during the school year, especially in younger teens, predicted lower cumulative grade point average and more emotional distress by college age.
