Structural biology: Special delivery

Bulky globular proteins require specialized transport systems for insertion into membranes. Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have determined the structure of such a system for the first time, and propose that it exploits the principle of the airlock.

SwRI-led team identifies low-energy solar particles from beyond Earth near the Sun

Using data from NASA's Parker Solar Probe (PSP), a team led by Southwest Research Institute identified low-energy particles lurking near the Sun that likely originated from solar wind interactions well beyond Earth orbit. PSP is venturing closer to the Sun than any previous probe, carrying hardware SwRI helped develop. Scientists are probing the enigmatic features of the Sun to answer many...

The Lancet Infectious Diseases: First clinical trial of antibody to neutralize henipaviruses finds it is safe and well tolerated in healthy volunteers

The first ever treatment for preventing a group of viruses from causing potentially lethal infections has been tested in a phase I clinical trial, and was found to be safe and able to neutralize the viruses, according to results from 40 patients published in The Lancet Infectious Diseases journal. The trial was conducted in healthy participants and further trials will be needed to demonstrate its...

UNH researchers find clues to how hazardous space radiation begins

Scientists at the University of New Hampshire have unlocked one of the mysteries of how particles from flares on the sun accumulate at early stages in the energization of hazardous radiation that is harmful to astronauts, satellites and electronic equipment. Using data from NASA's Parker Solar Probe, they observed one of the largest events that shows how plasma is released after a solar flare can...

Value transformation framework model seeks to guide transition to value-based healthcare

With a new focus on quality of care and outcomes achieved, healthcare organizations are challenged to make the transition to value-based care. A model called the Value Transformation Framework (VTF) provides a structured, step-by-step approach to help guide the shift to value-based healthcare, reports a paper in the Journal for Healthcare Quality (JHQ), the peer-reviewed journal of the National...

Viscosity measurements offer new insights into the earth's mantle

An international research group with Dr. Longjian Xie from the Bavarian Research Institute of Experimental Geochemistry & Geophysics (BGI) of the University of Bayreuth has succeeded for the first time in measuring the viscosity that molten solids exhibit under the pressure and temperature conditions found in the lower earth mantle. The data obtained support the assumption that a...

Water, water everywhere -- and it's weirder than you think

Researchers at The University of Tokyo show that liquid water has 2 distinct molecular arrangements: tetrahedral and non-tetrahedral. By computer simulations and analysis of X-ray scattering data, the researchers were able to settle a very old controversy in science.

Weather radar records drastic drop in mayfly populations

Researchers at the University of Oklahoma, the University of Notre Dame and Virginia Tech applied radar technology -- the same used for meteorology -- to quantify the number of mayflies that emerged annually from two different bodies of water: the Upper Mississippi River and the Western Lake Erie Basin. Their goal was to characterize the size of these swarms using the same technique a...
