An international team of researchers has discovered a new chemical compound that consists of a single element―boron. Chemical compounds are conventionally defined as substances consist of two or more elements, but the researchers found that a high pressure and temperature pure boron can assume two distinct forms that bond together to create a novel 'compound' called boron boride.

COROT has found the smallest terrestrial planet ever detected outside the Solar System. The amazing planet is less than twice the size of Earth and orbits a Sun-like star. Its temperature is so high that it is possibly covered in lava or water vapour.
 
About 330 exoplanets have been discovered so far, most of which are gas giants with characteristics similar to Jupiter and Neptune.   The new find, COROT-Exo-7b, is different: its diameter is less than twice that of Earth and it orbits its star once every 20 hours. It is located very close to its parent star, and has a high temperature, between 1000 and 1500°C. Astronomers detected the new planet as it transited its parent star, dimming the light from the star as it passed in front of it. 

Researchers at the Johns Hopkins University School of Medicine are one gene closer to understanding schizophrenia and related disorders.

Schizophrenia is a varied condition with a number of symptoms not shared by all affected. This could be one reason why it's been difficult to identify genes that contribute to the condition. 

To address this, the team first rigorously separated the 73 different symptoms into nine distinct factors associated with the condition—prodromal, negative, delusion, affective, scholastic, adolescent sociability, disorganization, disability, hallucination.

Green tea products have become regarded as a valuable health supplement and studies have shown evidence of its benefit against a variety of diseases, including cancer.   In animal studies, an antioxidant compound in green tea called the EGCG polyphenol (epigallocatechin gallate) has been shown to be a potent anticancer agent, with effects demonstrated against leukemia, as well as lung, prostate, colon, and breast cancer. Among other properties, EGCG binds to a common protein in tumors called GRP78 (which is responsible for preventing cell death) and inhibits its function, thereby assisting in the death of tumor cells. 

Gardening can offer enough moderate physical activity to keep older adults in shape but Kansas State researchers writing in the journal HortScience say that among the other health benefits of gardening is keeping older hands strong and nimble.

"One of the things we found is that older adults who are gardeners have better hand strength and pinch force, which is a big concern as you age," said Candice Shoemaker, K-State professor of horticulture.

A study reveals that the severity of learning disorders may depend not only on the child's environment but also on the mother's environment when she was young.

The researchers studied the brain function of pre-adolescent mice with a genetically-created defect in memory. When these young mice were enriched by exposure to a stimulating environment – including novel objects, opportunities for social interaction and voluntary exercise – for two weeks, the memory defect was reversed. The work showed that this enhancement was remarkably long-lasting because it was passed on to the offspring even though the offspring had the same genetic mutation and were never exposed to an enriched environment.
