Phys.org / Boys ditch books when schools close—girls keep reading: Study
When holidays or pandemics shut down schools, gender differences in children's reading habits widen; boys stop reading, while girls continue, according to a new study from the University of Copenhagen. The researchers say ...
Phys.org / Mammal cloning cannot be endless: Mouse line fails at generation 58
There is a limit on how many times a mammal can be cloned before suffering "mutational meltdown," Japanese scientists have discovered, after making 1,200 clones over two decades that started off with a single mouse.
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 / 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 / Nanoparticles enable large-scale production of advanced cell therapies
Researchers from Xi'an Jiaotong-Liverpool University (XJTLU) in China have developed a streamlined process that makes it easier to produce tiny therapeutic particles released by cells, called exosomes, which are being explored ...
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 / 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 / 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 / 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 / 'Gray-box' AI reveals why catalysts work while speeding discovery
Self-driving laboratories (SDLs) powered by artificial intelligence (AI) are rapidly accelerating materials discovery, but can they also explain their results? Researchers from the Theory Department of the Fritz Haber Institute, ...
