VCU physicists discover a tri-anion particle with colossal stability

Dom, 09/17/2017 - 22:00
A team in the lab of Puru Jena, Ph.D., a distinguished professor in the Department of Physics in the College of Humanities and Sciences at Virginia Commonwealth University, has created the most stable tri-anion particle currently known to science. A tri-anion particle is a combination of atoms that contains three more electrons than protons. This discovery is novel because previously known tri-anion particles were unstable due to their numerical imbalance.

NASA sees Tropical Storm Norma kicking up surf in Mexico

Dom, 09/17/2017 - 22:00
NASA-NOAA's Suomi NPP satellite passed over Tropical Storm Norma when it was just 145 miles south-southwest of Cabo San Lucas, Mexico, close enough to create rough ocean conditions and bring rain to Baja California.

Just squeeze in -- when spaces are tight, nature loosens its laws

Dom, 09/17/2017 - 22:00
It turns out that when they're in a hurry and space is limited, ions, like people, will find a way to cram in -- even if that means defying nature's norms. Recently published research from an international team of scientists, including Drexel University's Yury Gogotsi, PhD, shows that the charged particles will actually forgo their 'opposites attract' behavior, called Coulombic ordering, when confined in the tiny pores of a nanomaterial.

Eight children born after uterus transplants

Dom, 09/17/2017 - 22:00
Eight children born -- and the first robot-assisted operation performed. These are some of the results of 18 years of research at Sahlgrenska Academy on uterus transplants. In Gothenburg, the elite of the research world in the field are now gathering for their first congress.

NASA finds a pinhole eye in Hurricane Otis

Dom, 09/17/2017 - 22:00
Over the course of three days, Otis transitioned from a struggling tropical depression into a powerful hurricane in the Eastern Pacific Ocean. NASA-NOAA's Suomi NPP satellite captured an image of Hurricane Otis, showing a pinhole eye.

RNA discovery could help boost plant heat, drought tolerance

Dom, 09/17/2017 - 22:00
The discovery of a RNA that can increase drought and salt tolerance in thale cress could illuminate a new research approach and hold implications for other plants, including food crops.

Scientists show molecular basis for ants acting as 'bodyguards' for plants

Dom, 09/17/2017 - 22:00
Though you might not think of ants as formidable bodyguards, some do an impressive job protecting plants from enemies. Examing the relationship between the Amazon rainforest plant Cordia nodosa in Peru and the ant species Allomerus octoarticulatus, University of Toronto scientists found the degree to which the ants express two genes significantly impacts the amount of protection they provide to their hosts.

An effective way to eliminate atrazine and its by-products in surface water

Dom, 09/17/2017 - 22:00
Atrazine, widely used as a weedkiller, is known to have harmful effects on aquatic wildlife and presents a risk to human health by altering the action of certain hormones. In a study published recently in Water Research, a team of researchers led by INRS professor Patrick Drogui compares various processes used to degrade atrazine, one of the most common pesticides detected in surface water in Quebec.

Microscopic technique for detecting microbial life in enceladus water plumes

Dom, 09/17/2017 - 22:00
A new study has demonstrated the potential to use digital holographic microscopy (DHM) to detect microorganisms and evidence of life in water collected from the plume rising from the surface of Saturn's icy moon Enceladus.

Myth Debunked that OCD Is Associated With Superior Intelligence

Dom, 09/17/2017 - 22:00
The researchers conducted a meta-analysis of all the available literature on IQ in OCD samples versus non-psychiatric controls (98 studies), and found that contrary to the prevailing myth, OCD is not associated with superior IQ, but with normative IQ that is slightly lower compared to control samples. The authors suggested that the small reduction in IQ scores in OCD sufferers may be largely attributed to OCD-related slowness and not to intellectual ability.

New quantum phenomena in graphene superlattices

Dom, 09/17/2017 - 22:00
Graphene Flagship researchers show the first new type of quantum oscillation to be reported for thirty years. It is the first of its kind to be present at high temperature and on the mesoscale and sheds light on the Hofstadter butterfly phenomenon.

Step towards better 'beyond lithium' batteries

Dom, 09/17/2017 - 22:00
A step towards new 'beyond lithium' rechargeable batteries with superior performance has been made by researchers at the University of Bath.

To predict how climate change will affect disease, researchers must fuse climate science and biology

Dom, 09/17/2017 - 22:00
To predict how climate change will affect disease, researchers must fuse climate science and biology, according to a Princeton University review.

Re-interventions are common in long-term survivors of childhood heart operation

Dom, 09/17/2017 - 22:00
Among patients who undergo childhood heart surgery for the severe birth defect single-ventricle disease, two-thirds of survivors require a surgical or catheter-based procedure within 20 years. Pediatric cardiology researchers note that doctors should counsel families about the likelihood of re-interventions.

HIV-AIDS: Following your gut

Dom, 09/17/2017 - 22:00
Researchers at the University of Montreal Hospital Research Centre (CRCHUM) have discovered a way to slow viral replication in the gastrointestinal tract of people infected by HIV-AIDS. This advance, published in JCI Insight, might well lead to the development of a new therapeutic strategy to supplement antiretroviral therapy (ART), improving the control of viral replication in HIV-infected persons and preventing complications associated with chronic infection.

Changes in nonextreme precipitation may have not-so-subtle consequences

Dom, 09/17/2017 - 22:00
Major floods and droughts receive a lot of attention in the context of climate change, but University of Illinois researchers analyzed over five decades of precipitation data from North America to find that changes in nonextreme precipitation are more significant than previously realized and larger than those in extreme precipitation. These changes can have a strong effect on ecosystems, agriculture, infrastructure design and resource management, and point to a need to examine precipitation in a more nuanced, multifaceted way.

New evidence for small, short-lived drops of early universe quark-gluon plasma?

Dom, 09/17/2017 - 22:00
Particles emerging from even the lowest energy collisions of small deuterons with large heavy nuclei at the Relativistic Heavy Ion Collider a US Department of Energy Office of Science User Facility for nuclear physics research at DOE's Brookhaven National Laboratory -- exhibit behavior scientists associate with the formation of a soup of quarks and gluons, the fundamental building blocks of nearly all visible matter.

NASA sees Talim now extra-tropical

Dom, 09/17/2017 - 22:00
Tropical Storm Talim made landfall on Kyushu, the large island of southwestern Japan, where it weakened to an extra-tropical storm. NASA-NOAA's Suomi NPP satellite captured an image of the storm after its transition.

Dogs' social skills linked to oxytocin sensitivity

Dom, 09/17/2017 - 22:00
The tendency of dogs to seek contact with their owners is associated with genetic variations in sensitivity for the hormone oxytocin, according to a new study from Linköping University, Sweden. The results have been published in the scientific journal Hormones and Behavior and contribute to our knowledge of how dogs have changed during their development from wolf to household pet.
