Russian scientists deny climate model of IPCC
Scientists from Tomsk Polytechnic University revealed new data on accelerating permafrost degradation in the East Siberian Arctic Shelf, which really threatens by huge emissions of bubble methane into the atmosphere and breaks the climate model of the Intergovernmental Panel on Climate Change (IPCC). Study findings were published in Nature Communications.

Skewing the aim of targeted cancer therapies
The aim of targeted gene-based cancer therapies could often be skewed from the start. A widespread concept about how cells produce proteins proved incorrect 62 percent of the time in a new study in ovarian cancer cells on the relationship between RNA and protein levels.

Artificial blood vessels mimic rare accelerated aging disease
Biomedical engineers have grown miniature human blood vessels using stem cells taken from patients with an extremely rare genetic disease called progeria that causes symptoms resembling accelerated aging in children. The blood vessels exhibit many of the symptoms and drug reactions associated with progeria and will help doctors and researchers screen potential therapeutics for the disease, and other rare diseases, more rapidly.

How head-on collisions of DNA protein machines stop replication
Head-on collisions between the protein machines that crawl along chromosomes can disrupt DNA replication and boost gene mutation rates. This may be one of the ways bacteria control their evolution by accelerating mutations in key genes when coping with new conditions. Some mutations may help bacteria survive hostile environments, resist antibiotics or fend off immune attacks

Get them while they're young: Astronomers catch exploding supernova early
Thanks to a global network of telescopes, astronomers have caught the fleeting explosion of a Type Ia supernova in unprecedented detail. Because this type of supernova is commonly used as a cosmic yardstick, a better understanding of how they form could have implications for future dark energy measurements.

Smartphone tracking shows fear affects where youth spend time
Youth spend less time in their neighborhoods if area residents have a high fear of crime, according to a new study that used smartphones to track kids' whereabouts. Researchers found that adolescents aged 11 to 17 spent over an hour less each day on average in their neighborhoods if residents there were very fearful, compared to kids from areas perceived as being safer.

New ultrathin semiconductor materials exceed some of silicon's 'secret' powers
Chip makers appreciate what most consumers never knew: silicon's virtues include the fact that it 'rusts' in a way that insulates its tiny circuitry. Two new ultrathin materials share that trait and outdo silicon in other ways that make them promising materials for electronics of the future.

Test uses nanotechnology to quickly diagnose Zika virus
Currently, testing for Zika requires that a blood sample be refrigerated and shipped to a medical center or laboratory, delaying diagnosis and possible treatment. Now, Washington University in St. Louis researchers have developed a test that quickly can detect the presence of Zika virus in blood. Although the new proof-of-concept technology has yet to be produced for use in medical situations, test results can be determined in minutes, and the materials do not require refrigeration.

OU biologist receives $1.2 million NSF grant in support of ecological research
A University of Oklahoma biology professor, Michael E. Kaspari, has been awarded a $1.2 million National Science Foundation grant to study MacroSystems ecology--exploring how Earth's temperature, precipitation and biogeochemistry govern the abundance, diversity and activity of ecological communities. Kaspari will test these models by generating the first standardized field data from entire communities of ground dwelling arthropods--an invertebrate animal having an exoskeleton, a segmented body and paired jointed appendages.
