Clues to how hazardous space radiation begins
- ScienceDaily
- 20/2/3 22:28
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...

A new study finds the value of using 'parentese,' an exaggerated speaking style that conveys total engagement with a child.
How ants get angry: Precise 'lock and key' process regulates aggression, acceptance
- ScienceDaily
- 20/2/3 20:54
Scientists report definitive evidence of a mechanism within ants that is responsible for unlocking aggression. The research -- the first to pinpoint this mechanism and its precise role in ant biology -- reports a social characteristic which could help account for their evolutionary success.
Low-energy solar particles from beyond Earth found near the Sun
- ScienceDaily
- 20/2/3 20:15
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...
Making high-temperature superconductivity disappear to understand its origin

- 20/2/3 20:15
Purely electronic interactions could be behind copper-oxygen compounds conducting electricity without resistance at relatively high temperatures.
Building a safer CAR-T therapy
- ScienceDaily
- 20/2/3 20:15
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.
The one ring -- to track your finger's location
- ScienceDaily
- 20/2/3 20:15
Researchers have created AuraRing, a ring and wristband combination that can detect the precise location of someone's index finger and continuously track hand movements.
'Wristwatch' monitors body chemistry to boost athletic performance, prevent injury
- ScienceDaily
- 20/2/3 20:15
Engineering researchers have developed a device the size of a wristwatch that can monitor an individual's body chemistry to help improve athletic performance and identify potential health problems. The device can be used for everything from detecting dehydration to tracking athletic recovery, with applications ranging from military training to competitive sports.
Lower protein diet may lessen risk for cardiovascular disease
- ScienceDaily
- 20/2/3 20:15
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
- ScienceDaily
- 20/2/3 20:14
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
- ScienceDaily
- 20/2/3 20:14
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
- ScienceDaily
- 20/2/3 20:14
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.
Flickering light mobilizes brain chemistry that may fight Alzheimer's
- ScienceDaily
- 20/2/3 20:14
The promise of flickering light to treat Alzheimer's takes another step forward in this new study, which reveals stark biochemical mechanisms: 40 Hertz stimulus triggers a marked release of signaling chemicals.
How the development of skulls and beaks made Darwin's finches one of the most diverse species
- ScienceDaily
- 20/2/3 20:14
Darwin's finches are among the most celebrated examples of adaptive radiation in the evolution of modern vertebrates and now a new study has provided fresh insights into their rapid development and evolutionary success.
New quantum switch turns metals into insulators
- ScienceDaily
- 20/2/3 20:14
Researchers have demonstrated an entirely new way to precisely control electrical currents by leveraging the interaction between an electron's spin and its orbital rotation around the nucleus.
If cancer were easy, every cell would do it
- ScienceDaily
- 20/2/3 20:14
A new article puts an evolutionary twist on a classic question. Instead of asking why we get cancer, researchers use signaling theory to explore how our bodies have evolved to keep us from getting more cancer.
Chemists unveil the structure of an influenza B protein
- ScienceDaily
- 20/2/3 20:14
Chemists have discovered the structure of an influenza B protein called BM2, a finding that could help researchers design drugs that block the protein and help prevent the virus from spreading.
For complex decisions, narrow options down to two
