How much snow accumulates in North America each year? More than scientists thought

Mar 13 2018 - 00:03
Scientists have revised an estimate of snow volume for the entire continent, and they've discovered that snow accumulation in a typical year is 50 percent higher than previously thought. Researchers at The Ohio State University place the yearly estimate at about 1,200 cubic miles of snow. If spread evenly across the surface of the continent from Canada to Mexico, the snow would measure a little over 7.5 inches deep.

Russian physicists make toy asteroids and blast them with a laser

Mar 13 2018 - 00:03
Researchers created small copies of asteroids in the laboratory, and then destroyed them with lasers. The nanosecond laser pulse served as an experimental substitute for a nuclear explosion. The experiments showed high efficiency of nuclear anti-asteroid defense. The study suggests the most effective asteroid destruction criteria, such as the explosion energy needed to eliminate a dangerous object on a collision course with Earth.

High prices are just one reason Americans spend more on healthcare than Europeans

Mar 13 2018 - 00:03
High drug prices as well as the excessive use of imaging and surgical procedures, and excessive administrative burdens contribute the majority to America's health care overspending compared to Europe, argues policy expert Ezekiel J. Emanuel, MD, PhD, chair of the department of Medical Ethics and Health Policy at the Perelman School of Medicine at the University of Pennsylvania, in an editorial in this week's JAMA.

US continues to spend much more on health care than other countries, driven by prices of physician and hospital services, pharmaceuticals

Mar 13 2018 - 00:03
The United States spent nearly twice as much as other high-income countries on medical care but did less well on many population health outcomes despite similar utilization.  Spending differences were driven primarily by prices for labor and goods, including pharmaceuticals, devices and administrative costs.

Mesenchymal stem cell therapy: Holding promise for feline inflammatory diseases

Mar 13 2018 - 00:03
Stem cell therapy is acknowledged as having great potential for the treatment of a variety of diseases in both people and animals. The use of bone marrow-derived stem cells is well established in the treatment of human cancer patients, and veterinary applications for bone marrow- and adipose-derived stem cells are being evaluated

Study IDs 'white graphene' architecture with unprecedented hydrogen storage capacity

Mar 13 2018 - 00:03
Rice University engineers have zeroed in on the optimal architecture for storing hydrogen in 'white graphene' nanomaterials -- a design like a Lilliputian skyscraper with 'floors' of boron nitride sitting one atop another and held by boron nitride pillars.

Prevent antibiotic resistances from spreading: Rapid test helps administering the 'correct' drug

Mar 13 2018 - 00:03
Multi-resistant microbes are a growing danger. The often unnecessary and mass use of antibiotics causes the impassivity of pathogens against drugs. Infections that were easily curable up to now, may become life threatening. A new rapid test will give information on which available antibiotic is still effective. Faster diagnostics allow a personalized therapy and saves lives. A requirement for prevention of spreading antibiotic resistances is a targeted, economical and responsible application of broad-spectrum and last resort antibiotics.

Where language pionieer Paul Broca and alien music meet

Mar 13 2018 - 00:03
What might alien music sound like? Would it be structured hierarchically as our music is with verses and a chorus? Would we even be able to appreciate it? Vincent Cheung from Max Planck Institute for Human Cognitive and Brain Sciences, thinks the answer would be yes, assuming it was predicated on local and non-local dependencies. His research published this week in Scientific Reports explains what exactly that means.

Ash from dinosaur-era volcanoes linked with shale oil, gas

Mar 13 2018 - 00:03
Nutrient-rich ash from an enormous flare-up of volcanic eruptions toward the end of the dinosaurs' reign kicked off a chain of events that led to the formation of shale gas and oil fields from Texas to Montana.

Why economic growth does not necessarily contribute to human happiness

Mar 13 2018 - 00:03
Economic growth in developed countries has a dual effect. On one hand, people's living standards and consumer spending are on the rise, but on the other hand, this does not necessarily make people happy and may in fact erode subjective well-being and lead to economic crises. A new study by an international team that included Francesco Sarracino, HSE LCSR Senior Associate Researcher, examines the reasons behind this phenomenon.

A new twist to an old story of cellular signaling in the eye of a fly

Mar 13 2018 - 00:03
Recent work from the National Centre for Biological Sciences (NCBS), Bangalore, has shown that the regeneration of a signaling molecule, phosphatidylinositol 4,5 bisphosphate (PIP2), is not as simple as it was thought to be. Experimental work from Raghu Padinjat's group and mathematical modelling by Sandeep Krishna's team from the Simons Centre for Living Machines at NCBS shows that the decades-old model of the biochemical cycle may have two unknown steps that could change the way scientists interpret experimental data.

IUPUI field-data study finds no evidence of racial bias in predictive policing

Mar 13 2018 - 00:03
While predictive policing aims to improve the effectiveness of police patrols, there is concern that these algorithms may lead police to target minority communities and result in discriminatory arrests. An IUPUI School of Science computer scientist conducted the first study to look at real-time field data from Los Angeles, CA and found predictive policing did not result in biased arrests.

Background radiation in UAE's agricultural topsoil found to be lower than global average

Mar 13 2018 - 00:03
The first civilian nuclear power plant in the Eastern Region of Arabian Desert, and specifically in the United Arab Emirates (UAE), will be operating four reactors between (2018- 2020). Before the construction of any regulated nuclear facility, it is essential to investigate the environmental background radiation level in the country. This study determines the primordial radionuclides concentrations obtained from 145 soil samples collected from multiple agriculture farms in the UAE.
