Phys.org / Mathematical framework maps landscape of student knowledge via short quizzes
When we learn something new, that information does not exist in isolation. It integrates into the complex landscape of our knowledge, forging connections with existing ideas and opening up possibilities for new learning. ...
Phys.org / Boron arsenide semiconductor sets record in quantum vibrations
You may not be able to hear it, but all solid materials make a sound. In fact, atoms—bound in lattices of chemical bonds—are never silent nor still: Under the placid surface of each and every object in our surroundings, a ...
Phys.org / XRISM identifies gamma Cas X-ray origin, solving a 50-year-old stellar mystery
Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary ...
Phys.org / Stolen chloroplasts maintained by host-made proteins offer clues to plant cell origins
Every plant cell is the product of a biological merger billions of years ago. Chloroplasts are key structures in plants and algae that capture sunlight, but originally they were free-living bacteria that took up residence ...
Phys.org / Single-cell imaging and machine learning reveal hidden coordination in algae's response to light stress
Researchers from several Parisian institutions have worked together to develop a non-destructive approach to study how unicellular organisms respond to stress, focusing on cell-to-cell differences. Working together, the researchers ...
Phys.org / New lipid nanoparticle design improves precision of mRNA vaccine delivery
Penn Engineers have redesigned a key component of lipid nanoparticles (LNPs), the delivery vehicles behind mRNA vaccines, to steer the particles toward lymph nodes while reducing off-target delivery to the liver. The advance ...
Phys.org / Why cooperative workplaces boost your sense of freedom
Jack Welch, the legendary General Electric CEO, was infamous for firing the bottom 10% of his workforce every year, without exception. The company's market cap rose substantially during Welch's tenure, but his "rank and yank" ...
Phys.org / Highly and casually active citizen scientists contribute equally valuable data
The word "nemotia" is a neologism, a newly coined term that in this case, describes the sense of overwhelmingness and disconnect accompanying the thought that nothing you do will ever make a difference. If this describes ...
Phys.org / Preparing for the next pandemic: Scientists discover a new class of influenza antivirals
Researchers from Leiden University, University of York, University of Barcelona/IQTCUB/ICREA and The Francis Crick Institute report a new class of experimental compounds that powerfully block influenza viruses. The findings ...
Phys.org / Snow flies produce bursts of heat and proteins to avoid freezing, new study finds
In a new study, Northwestern University scientists explored how snow flies—small, wingless insects that crawl across snow to find mates and lay eggs—survive in freezing cold temperatures. They discovered this snow-dwelling ...
Phys.org / The truth of timekeeping lies within: Key developments in understanding circadian rhythms
Almost all living things have an internal 24-hour clock that remains accurate regardless of temperature or other environmental changes. This clock is a highly sophisticated yet simple timekeeping mechanism that is critically ...
Phys.org / GNSS stations reveal fourfold turbulence during Antarctica's Ross Ice Shelf melt
Global navigation satellite systems (GNSS), which include GPS, are traditionally used for positioning, timing, and mapping information. In an open-access study published Feb. 27 in Geophysical Research Letters, MIT Haystack ...
