A research team from Tokyo Institute of Technology (Tokyo Tech) and Waseda University have successfully produced high-quality thin film monocrystalline silicon with a reduced crystal defect density down to the silicon wafer level at a growth rate that is more than 10 times higher than before. In principle, this method can improve the raw material yield to nearly 100%.
Researchers at Vanderbilt University Medical Center have found a way to search genetic data in electronic health records to identify undiagnosed genetic diseases in large populations so treatments can be tailored to the actual cause of the illness.
It is a long-cherished dream: Removing the inert greenhouse gas carbon dioxide from the atmosphere and using it as a basic material for the chemical industry. This could address two major problems at once by containing climate change and at the same time reducing the dependence on oil. Physico-chemists at the University of Bonn have discovered a new way to create a highly reactive form of carbon dioxide with the help of laser pulses.
In a study that has implications for humans with inflammatory diseases, researchers have found that, given over a six-week period, the artificial sweetener sucralose, known by the brand name Splenda, worsens gut inflammation in mice with Crohn's disease, but had no substantive effect on those without the condition.
The idea that it might be possible to be overweight or obese but not at increased risk of heart disease, otherwise known as the 'obesity paradox', has been challenged by a study of nearly 300,000 people published in in the European Heart Journal. The research shows that the risk of heart and blood vessel problems, such as heart attacks, strokes and high blood pressure, increases as body mass index (BMI) increases beyond a BMI of 22-23 kg/m2.
A study from UT Southwestern's Peter O'Donnell Jr. Brain Institute demonstrates that a bird's song can be altered -- to the syllable -- by activating and deactivating a neuronal pathway responsible for helping the brain determine whether a vocalization is performed correctly.
