New study finds university health schools' use of holistic admissions has positive impact
A new national study finds that health professions schools report an overall positive impact from the use of holistic review -- a university admissions process that assesses an applicant's unique experiences alongside traditional measures of academic achievement such as grades and test scores. The report, Holistic Admission in the Health Professions, released today is the first large-scale study to examine the prevalence and effectiveness of holistic review across multiple health disciplines at universities nationwide.

At dusk and dawn: Scientists pinpoint biological clock's synchronicity
Scientists have uncovered how pacemaker neurons are synchronized at dusk and dawn in order to maintain the proper functioning of their biological clocks. Their findings enhance our understanding of how sleep-wake cycles are regulated and offer promise for addressing related afflictions.

Smithsonian scientists discover coral's best defender against an army of sea stars
Coral reefs face a suite of perilous threats in today's ocean. From overfishing and pollution to coastal development and climate change, fragile coral ecosystems are disappearing at unprecedented rates. Despite this trend, some species of corals surrounding the island of Moorea in French Polynesia have a natural protector in their tropical environment: coral guard-crabs. New research has helped unravel the complex symbiotic relationship between these crabs and the coral reefs they live in and defend.

Diuretics in proton pump inhibitor-associated hypomagnesemia
Proton pump inhibitor therapy is associated with hospitalization for hypomagnesemia, particularly among patients also receiving diuretics, according to research published this week in PLOS Medicine. The study, conducted by David Juurlink of the University of Toronto and colleagues, suggests that physicians reconsider long-term PPI therapy for patients with a diagnosis of hypomagnesemia or concurrent use of diuretics.

Rehospitalization in younger patients
Older adults often are readmitted after hospitalization for heart failure, pneumonia, and acute myocardial infarction, a significant issue that has caused Medicare to target hospitals with high 30-day readmission rates for financial penalties. Older adults are also often admitted for reasons other than the original hospitalization. This vulnerability to readmission has been referred to as 'post-hospital syndrome.' However, whether younger patients also experience a similar pattern of readmission has not been well studied.

Laser-guided sea monkeys show how zooplankton migrations may affect global ocean currents
Sea monkeys have captured the popular attention of both children and aquarium hobbyists because of their easily observable life cycle. Physicists are interested in a shorter-term pattern: Like other zooplankton, brine shrimp vertically migrate in large groups throughout the day in response to changing light conditions. New research suggests that the collective movement of small marine organisms could affect global ocean circulation patterns on a level comparable to the wind and the tides.

Chemical interactions between silver nanoparticles and thiols: A comparison of mercaptohexanol again
The interaction between citrate capped silver nanoparticles and two different thiols, mercaptohexanol and cysteine, was investigated. The electrochemical and spectroscopy data showed that the thiols interacted with silver nanoparticles in a significantly contrasting manner.

Deceptive-looking vortex line in superfluid led to twice-mistaken identity
So long, solitons: University of Chicago physicists have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence of solitons -- exotic, solitary waves. Instead, they explain, the result was due to more pedestrian, whirlpool-like structures in the fluid. They published their explanation in the Sept. 19 issue of Physical Review Letters.

NASA-funded rocket has 6 minutes to study solar heating
On Sept. 30, 2014, a sounding rocket will fly up into the sky -- past Earth's atmosphere that obscures certain wavelengths of light from the sun -- for a 15-minute journey to study what heats up the sun's atmosphere. This is the fourth flight for the Very high Angular Resolution Ultraviolet Telescope, or VAULT, will launch from the White Sands Missile Range near Las Cruces, N.M.

NASA support key to glacier mapping efforts

This new data will help researchers better project future changes to glaciers and ice sheets, and ultimately, sea level.

A 'frenemy' in Parkinson's disease takes to crowdsourcing
Researchers have found that a key neuronal protein called alpha-synuclein normally gathers in synapses, where aggregates of it help regulate neurotransmissions. In overabundance, though, a-synuclein can choke off communication altogether, leading to neuronal death and related diseases.

An apple a day could keep obesity away
Scientists at Washington State University have concluded that nondigestible compounds in apples -- specifically, Granny Smith apples -- may help prevent disorders associated with obesity. The study, thought to be the first to assess these compounds in apple cultivars grown in the Pacific Northwest, appears in October's print edition of the journal Food Chemistry.

Tree killers, yes, fire starters, no: Mountain pine beetles get a bad rap, study says
New research led by the University of Wisconsin-Madison and the Washington State Department of Natural Resources provides some of the first rigorous field data to test whether fires that burn in areas impacted by mountain pine beetles are more ecologically severe than in those not attacked by the native bug. In a study published this week, UW-Madison zoology professor Monica Turner and her graduate student, Brian Harvey, show pine beetle outbreaks contributed little to the severity of six wildfires in 2011.
