Houseplants could one day monitor home health

Jul 20 2018 - 00:07
In a perspective published in the July 20 issue of Science, a team of University of Tennessee faculty and a student from two unrelated disciplines -- plant sciences and architectural design -- explore the future of houseplants as aesthetically pleasing and functional sirens of home health. Their idea is to genetically engineer house plants to serve as subtle alarms that something is amiss in our home and office environments.

Wave energy converters are not geared towards the increase in energy over the last century

Jul 20 2018 - 00:07
Wave energy converters are designed to generate the maximum energy possible in their location and take a typical year in the location as a reference. Alongside the Irish Centre for Ocean Energy Research, researchers from various UPV/EHU centres have been exploring how ocean energy in Ireland has evolved during the last century. The results reveal an increase of up to 40%, which directly affects the output of the converters.

A peek into the interplay between sleep and wakefulness

Jul 20 2018 - 00:07
The ventrolateral preoptic nucleus (VLPO) in the brain plays a critical role in the initiation and maintenance of sleep, while the lateral posterior part of the hypothalamus contains neuronal populations implicated in maintenance of arousal. Now, a University of Tsukuba-centered study reveals that these arousal-related neurons are heavily innervated by GABAergic neurons in the preoptic area including the VLPO. The work provides important information to understand the mechanisms that control animals' sleep/wakefulness states.

The genes are not to blame

Jul 20 2018 - 00:07
Individualized dietary recommendations based on genetic information are currently a popular trend. A team at the Technical University of Munich (TUM) has systematically analyzed scientific articles and reached the following conclusion: There is no clear evidence for the effect of genetic factors on the consumption of total calories, carbohydrates, and fat. According to the current state of knowledge, the expedience of gene-based dietary recommendations has yet to be proven.

New findings on intercellular communication

Jul 20 2018 - 00:07
This is a nice example of a rather unexpected discovery: by studying the development of the blood vessels of the brain, researchers at Université libre de Bruxelles have just shed light on a question that was pending for 10 years! They provide a molecular mechanism conferring ligand specificity to Wnt signaling, an ancestral communication pathway present in all vertebrates. Their research is published in Science.

The cause of prostate cancer progression to incurable stage has likely been uncovered

Jul 20 2018 - 00:07
Researchers at the University of Oulu in Finland have discovered novel genes and mechanisms that can explain how a genomic variant in a single nucleotide polymorphism (SNP) rs11672691 influences prostate cancer aggressiveness. Their findings also suggest ways to improve risk stratification and clinical treatment for advanced prostate cancer. The study is published in the journal Cell.

Current noises of Majorana fermions

Jul 20 2018 - 00:07
Majorana fermions, also named 'Angel particles', has become a hot topic in recent years for their potential application in topological quantum computation. A recent theoretical study reveals the connection between current noises of Majorana system and the multiple Andreev reflections, providing a method for the experimental detection of Majorana fermions. This work is reported by SCIENCE CHINA Physics, Mechanics & Astronomy.
