Researchers find sudden cardiac death is associated with a thin placenta at birth

Researchers studying the origins of sudden cardiac death have found that in both men and women a thin placenta at birth was associated with sudden cardiac death. A thin placenta may result in a reduced flow of nutrients from the mother to the fetus. The authors suggest that sudden cardiac death may be initiated by impaired development of the autonomic nervous system in the womb, as a result of...

Researchers identify possible key to slow progression toward AIDS

Research has shown that HIV-positive people who progress to full blown AIDS slower than others carry a rare immune gene variant. Even among these people the speed of disease progression can vary widely. Researchers may have found a possible key to that variation -- a killer T-cell immune response that occurs early on in HIV infection and targets a section -- or epitope -- of the HIV protein called...

Researchers propose new way to save Africa's beleaguered soils

A Washington State University researcher and colleagues make a case in the journal Nature for a new type of agriculture that could restore the beleaguered soils of Africa and help the continent feed itself in the coming decades. Their system, which they call "perenniation," mixes food crops with trees and perennial plants, which live for two years or more.

Revolutionary ultrathin, flat lens: Smart phones as thin as a credit card?

Scientists are reporting development of a revolutionary new lens -- flat, distortion-free, so small that more than 1,500 would fit across the width of a human hair -- capable in the future of replacing lenses in applications ranging from cell phones to cameras to fiber-optic communication systems. The advance, which could lead to smart phones as thin as a credit card, appears in ACS' journal Nano...

Robotic tuna is built by Homeland Security

Homeland Security's BIOSwimmer™ is a unmanned underwater vehicle designed for high maneuverability in harsh environments and hard-to-reach underwater places where inspection and security is necessary.

Scientists show biological mechanism can trigger epileptic seizures

Scientists have discovered the first direct evidence that a biological mechanism long suspected in epilepsy is capable of triggering the brain seizures - opening the door for studies to seek improved treatments or even preventative therapies. The researchers report Sept. 19 in Neuron that molecular disruptions in small neurons called granule cells - located in the dentate gyrus region of the brain...

Seaside publishes research supporting disease-modifying potential of STX209 for fragile X syndrome

Seaside Therapeutics today announced the publication of two papers in Science Translational Medicine, supporting its lead candidate, STX209 (arbaclofen), for the treatment of fragile X syndrome (FXS). The works presented highlight STX209 as a potential disease-modifying drug in preclinical studies, with improvement in social function in a clinical trial of patients with FXS.

Selective grazing and aversion to olive and grape leaves achieved in goats and sheep

Researchers from the Research Group on Ruminants led by Elena Albanell, lecturer in Animal and Food Science at Universitat Autonoma de Barcelona, have successfully achieved to prevent sheep and goats from chewing on the young leaves of olive trees and grapevines when grazing. By using the natural mechanism of conditioned taste aversion, researchers redirected the food preferences of ruminants,...

Self-forming biological scaffolding

A new model system of the cellular skeletons of living cells is akin to a mini-laboratory designed to explore how the cells' functional structures assemble. A paper about to be published in EPJ E by physicist Volker Schaller and his colleagues from the Technical University Munich, Germany, presents one hypothesis concerning self-organization. It hinges on the findings that a homogeneous protein...

Sesame and rice bran oil lowers blood pressure, improves cholesterol

A blend of sesame and rice bran oil reduced blood pressure almost as well as a common medication. Those who used a combination of both the oil and medication had more than twice the drop in blood pressure compared to either the group taking medication alone, or those only supplementing their diet with the oil blend.

Single-atom writer a landmark for quantum computing

A research team led by Australian engineers has created the first working quantum bit based on a single atom in silicon, opening the way to ultra-powerful quantum computers of the future.In a landmark paper published today in the journal Nature, the team describes how it was able to both read and write information using the spin, or magnetic orientation, of an electron bound to a single phosphorus...

Split-dose preparation for colonoscopy increases precancerous polyp detection rates

A new study from researchers at the Mayo Clinic Arizona showed that system-wide implementation of a split-dose preparation as the primary choice for colonoscopy significantly improved both polyp detection rates and adenoma (precancerous polyp) detection rates, overall quality of the preparation, and colonoscopy completion rates. The study appears in the September issue of GIE: Gastrointestinal...

Stop diabetes with insulin tablets

Could a capsule of insulin crystals a day stop the development of type 1 diabetes? There are indications that this could be the case. In the international TrialNet study, which follows relatives of individuals with type 1 diabetes, researchers are investigating whether oral insulin could prevent or delay the disease.

Study unveils clue to the origin of dyslexia

Even though dyslexia is defined as a reading disorder, it also affects how a person perceives spoken language. It is widely known that individuals with dyslexia exhibit subtle difficulties in speech perception. In fact, these problems are even seen among infants from dyslexic families, well before reading is acquired. A new study by Northeastern University professor Iris Berent has uncovered a...

The key to cooperation? Think fast

A team of researchers trying to answer an age-old question about human goodness have found evidence for a "cooperation reflex." They show that when self-interest goes up against the common good, our intuitions favor cooperation, while stopping to think leads to selfishness.
