|Making ferromagnets stronger by adding non-magnetic elements|
|Fri, 23 Jun 2017 15:55:14 EDT|
Magnetic materials can be functionalized through a thoroughly unlikely method, report researchers: by adding amounts of the virtually non-magnetic element scandium to a gadolinium-germanium alloy.
|Genes, ozone, and autism|
|Fri, 23 Jun 2017 15:55:11 EDT|
Exposure to ozone in the environment puts individuals with high levels of genetic variation at an even higher risk for developing autism than would be expected just by adding the two risk factors together, a new analysis shows. The study is the first to look at the combined effects of genome-wide genetic change and environmental risk factors for autism.
|The mere presence of your smartphone reduces brain power, study shows|
|Fri, 23 Jun 2017 13:30:39 EDT|
Your cognitive capacity is significantly reduced when your smartphone is within reach — even if it’s off — suggests new research.
|Fungal toxins easily become airborne, creating potential indoor health risk|
|Fri, 23 Jun 2017 13:15:20 EDT|
Toxins produced by three different species of fungus growing indoors on wallpaper may become aerosolized, and easily inhaled. The findings likely have implications for 'sick building syndrome.
|Algorithm generates optimal origami folding patterns for any shape|
|Fri, 23 Jun 2017 13:15:17 EDT|
A new algorithm generates practical paper-folding patterns to produce any 3-D structure.
|Bioengineers create more durable, versatile wearable for diabetes monitoring|
|Fri, 23 Jun 2017 13:15:15 EDT|
Researchers are getting more out of the sweat they've put into their work on a wearable diagnostic tool that measures three diabetes-related compounds in microscopic amounts of perspiration. In a study, the team describes their wearable diagnostic biosensor that can detect three interconnected compounds - cortisol, glucose and interleukin-6 - in perspired sweat for up to a week without loss of signal integrity.
|Anti-epilepsy drug restores normal brain activity in mild Alzheimer's disease|
|Fri, 23 Jun 2017 13:15:12 EDT|
An anti-epileptic drug has been tested for its potential impact on the brain activity of patients with mild Alzheimer's disease. The team documented changes in patients' EEGs that suggest the drug could have a beneficial effect.
|Scientists recreate Californian Indian water bottles to study ancient exposure to chemicals|
|Fri, 23 Jun 2017 11:05:51 EDT|
Water bottles replicated in the traditional method used by Native Californian Indians reveal that the manufacturing process may have been detrimental to the health of these people.
|Sweet bribes for ants are key to crops bearing fruit, study shows|
|Fri, 23 Jun 2017 11:05:45 EDT|
Some flowering crops, such as beans and cotton, carefully manage the amount and sweetness of nectar produced on their flowers and leaves, to recruit colonizing ants which deter herbivores. This strategy balances their needs for defense and reproduction.
|Self-folding origami: Chemical programming allows Nafion sheets to fold and refold|
|Fri, 23 Jun 2017 11:05:32 EDT|
Plastic with a thousand faces: A single piece of Nafion foil makes it possible to produce a broad palette of complex 3-D structures. Researchers now describe how they use simple chemical 'programming' to induce the foil to fold itself using origami and kirigami principles. These folds can be repeatedly 'erased' and the foil can be 'reprogrammed'.
|Scientists work to develop heat-resistant 'cow of the future'|
|Fri, 23 Jun 2017 10:07:12 EDT|
More than half the cattle in the world live in hot and humid environments, including about 40 percent of beef cows in the United States. By using genomic tools, researchers aim to produce an animal with superior ability to adapt to hot living conditions and produce top-quality beef.
|Decades after the discovery of anti-obesity hormone, scant evidence that leptin keeps lean people lean, scientists say|
|Fri, 23 Jun 2017 10:07:10 EDT|
Decades after the discovery of anti-obesity hormone, scant evidence that leptin keeps lean people lean, scientists caution.
|Leisure activities lower blood pressure in Alzheimer's caregivers|
|Fri, 23 Jun 2017 10:07:08 EDT|
Going for a walk outside, reading, listening to music — these and other enjoyable activities can reduce blood pressure for elderly caregivers of spouses with Alzheimer’s disease, suggests a study.
|Tropical viruses: Coming soon to Europe£|
|Fri, 23 Jun 2017 10:06:21 EDT|
The mosquito-borne viral disease Chikungunya is usually found in tropical areas. Researchers have now discovered how climate change is facilitating the spread of the Chikungunya virus. Even if climate change only progresses moderately – as scientists are currently observing – the risk of infection will continue to increase in many regions of the world through the end of the 21st century. If climate change continues unchecked, the virus could even spread to southern Europe and the United States.
|Meteorite mystery solved with research on high pressure|
|Fri, 23 Jun 2017 10:06:19 EDT|
A research group has found a long-sought explanation for the apparent contradictions implicit in the composition of lunar and Martian meteorites. They were able to demonstrate how meteorites could contain within narrow spaces minerals whose formation conditions are quite different. These findings provide new impetus for meteorite research.
