Scientists present a new method for imaging individual electrons
Imagine going for an MRI scan of your knee. This scan measures the density of water molecules present in your knee, at a resolution of about one cubic millimeter—which is great for determining whether, for example, a meniscus in the knee is torn. B.....»»
New electron microscopy technique reveals complex spin structures at femtosecond timescales
Plasmons are collective oscillations of electrons in a solid and are important for a wide range of applications, such as sensing, catalysis, and light harvesting. Plasmonic waves that travel along the surface of a metal, called surface plasmon polari.....»»
Ferns" ancient resilience aids modern ecosystem recovery after disasters
Scientists have suggested an updated framework for the role of ferns in environmental recovery from disaster. Instead of competing with other organisms, ferns may act as facilitators that ease the way for other plants and animals to re-establish them.....»»
Avalanches, icy explosions and dunes: NASA is tracking New Year on Mars
Instead of a winter wonderland, the Red Planet's northern hemisphere goes through an active—even explosive—spring thaw. While New Year's Eve is around the corner here on Earth, Mars scientists are ahead of the game: The Red Planet completed a tri.....»»
Intense ribbons of rain also bring the heat, scientists say
The environmental threat posed by atmospheric rivers—long, narrow ribbons of water vapor in the sky—doesn't come only in the form of concentrated, torrential downpours and severe flooding characteristic of these natural phenomena. According to a.....»»
Scientists steer the development of stem cells to regenerate and repair organs
Investigators from Cedars-Sinai and the University of California, San Francisco (UCSF) have identified a new way to deliver instructions that tell stem cells to grow into specific bodily structures, a critical step in eventually regenerating and repa.....»»
Simulations of hominin Lucy help show how long distance running evolved in modern humans
A team of natural scientists, musculoskeletal specialists, and evolutionary biologists affiliated with several institutions in the U.K., working with a colleague from the Netherlands, has found via simulations, that the famous early hominin Lucy, cou.....»»

Chang"e-6 farside basalts reveal a reinforced lunar dynamo
The evolution of the lunar dynamo is crucial for understanding the moon's deep interior structure, thermal history, and surface environment. A study by Chinese scientists conducted paleomagnetic analyses on basalts returned by the Chang'e-6 mission a.....»»
Miniature sensor that detects toxic gas shows promising results in the lab
A team of scientists at UNSW Sydney have developed a highly sensitive miniature sensor that is able to detect low levels of the toxic gas nitrogen dioxide (NO2). The tiny, flexible sensor can detect the harmful gas in real-time without requiring an e.....»»
Compact on-chip polarimeter measures light polarization with high accuracy
Reliably measuring the polarization state of light is crucial for various technological applications, ranging from optical communication to biomedical imaging. Yet conventional polarimeters are made of bulky components, which makes them difficult to.....»»
New synthesis technique cuts drug development time and cost
A team of chemists from Scripps Research and Rice University has unveiled a novel method to simplify the synthesis of piperidines, a key structural component in many pharmaceuticals. The study, published in Science, combines biocatalytic carbon-hydro.....»»
Study reveals flies more vulnerable than bees to climate change
Despite their reputation as buzzing nuisances, flies serve a critical role as some of the Earth's most prolific pollinators—and new research led by Penn State scientists suggests they are increasingly at risk due to rising global temperatures......»»
By looking at individual atoms in tooth enamel, researchers are learning what happens to our teeth as we age
Teeth are essential for helping people break down the food they eat, and are protected by enamel, which helps them withstand the large amount of stress they experience as people chew away. Unlike other materials in the body, enamel has no way to repa.....»»
Plasma heating efficiency in fusion devices boosted by metal screens
Heating plasma to the ultra-high temperatures needed for fusion reactions requires more than turning the dial on a thermostat. Scientists consider multiple methods, one of which involves injecting electromagnetic waves into the plasma, the same proce.....»»
Newly identified mysterious fossil seed reveals Ice Age climate patterns
La Brea Tar Pits scientists have identified a previously unknown juniper species as Juniperus scopulorum, commonly known as the Rocky Mountain Juniper. The successful identification, along with the first-ever radiocarbon dating of these fossil plants.....»»
