Clues to how hazardous space radiation begins

Scientists 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 accelerate and pile up energetic...

Low-energy solar particles from beyond Earth found near the Sun

Scientists have identified low-energy particles lurking near the Sun that likely originated from solar wind interactions well beyond Earth orbit. NASA's Parker Solar Probe is venturing closer to the Sun than any previous probe. Scientists are probing the enigmatic features of the Sun to answer many questions, including how to protect space travelers and technology from the radiation associated...

Building a safer CAR-T therapy

A new study has devised a new type of chimeric antigen-receptor (CAR) T cell -- a family of promising immunotherapies for cancer -- that can be switched on and off on demand.

Lower protein diet may lessen risk for cardiovascular disease

A plant-based diet may be key to lowering risk for heart disease. Researchers determined that diets with reduced sulfur amino acids -- which occur in protein-rich foods, such as meats, dairy, nuts and soy -- were associated with a decreased risk for cardiovascular disease. The team also found that the average American consumes almost two and a half times more sulfur amino acids than the estimated...

How nature tells us its formulas

A team has developed methods with which these models can be directly obtained from experimental measurements. Instead of comparing the experimental results to theoretical model predictions, it is, in a certain sense, possible to measure the theory itself.

Viscosity measurements offer new insights into Earth's mantle

An international research group 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 bridgmanite-enriched rock layer was formed during the early history of the earth at a depth of around 1,000 kilometers.

Oil spill clean-up: Better method

Oil poses a considerable danger to aquatic life. Researchers have developed a new technology for the removal of such contaminations: Textiles with special surface properties passively skim off the oil and move it into a floating container. The scientists used surfaces from the plant kingdom as a model.

Tailor-made vaccines could almost halve rates of serious bacterial disease

New research has found that rates of disease caused by the bacterium Streptococcus pneumoniae could be substantially reduced by changing our approach to vaccination. Researchers combined genomic data, models of bacterial evolution and predictive modelling to identify how vaccines could be optimized for specific age groups, geographic regions and communities of bacteria.
