Genes, ozone, and autism

Fri, 06/23/2017 - 3:55pm
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.

Bioengineers create more durable, versatile wearable for diabetes monitoring

Fri, 06/23/2017 - 1:15pm
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, 06/23/2017 - 1:15pm
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.

Sweet bribes for ants are key to crops bearing fruit, study shows

Fri, 06/23/2017 - 11:05am
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.

Scientists work to develop heat-resistant 'cow of the future'

Fri, 06/23/2017 - 10:07am
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.

Tropical viruses: Coming soon to Europe?

Fri, 06/23/2017 - 10:06am
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, 06/23/2017 - 10:06am
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.

Dune ecosystem modelling

Fri, 06/23/2017 - 10:06am
Acacia longifolia, which is native to Australia, is a species which was cultivated in Portugal primarily to stabilize dunes and as an ornamental plant; now it has spread out uncontrollably in Portugal and into many ecosystems around the world. Using the acacia as an example, researchers show that the location has an effect on interaction with other species.

Equipping form with function

Fri, 06/23/2017 - 10:04am
Mechanical structures in steerable cars are optimized to fit exactly one particular shape of the toy. If designers want to reuse such a mechanism with different shapes, the necessary adjustments to the components were often unmanageable for non-experts. Scientists have developed an interactive design tool that allows users to easily adjust a mechanical template to the shape of their choice.

Child safety or parental duty: New study maps out core concepts in the vaccination debate

Fri, 06/23/2017 - 10:04am
The recent measles outbreak in Minnesota has been a sobering reminder of how highly concentrated populations of vaccination skeptics can elevate an entire community's risk of infection. Around the edges of every headline-grabbing outbreak, there's a vast range of opinions being circulated about the risks and benefits of early childhood immunization. The vaccination debate maintains a constant presence on social media platforms. These varied viewpoints caught the attention of scientists who are conducting a three-year study on the ways online interactions influence our beliefs.

Combined molecular biology test is the first to distinguish benign pancreatic lesions

Fri, 06/23/2017 - 10:04am
When performed in tandem, two molecular biology laboratory tests distinguish, with near certainty, pancreatic lesions that mimic early signs of cancer but are completely benign. The lesions almost never progress to cancer, so patients may be spared unnecessary pancreatic cancer screenings or operations. The two-test combination is the only one to date that can accurately and specifically identify these benign pancreatic lesions.

Is it okay for children to count on their fingers?

Fri, 06/23/2017 - 10:04am
Is it OK for children to count on their fingers? Generations of pupils have been discouraged by their teachers from using their hands when learning maths. But a new research article shows using fingers may be a much more important part of maths learning than previously thought.
