Examining how shape and chirality affects luminous molecules
They flash as a warning, glow red on standby mode, and light up your dinner table; light-emitting diodes (LEDs) have become indispensable in our daily lives. Somewhat less well-known, but just as ubiquitous, are organic light-emitting diodes, or OLED.....»»
Examining experiences of the pandemic requires a more critical eye, says researcher
The coronavirus pandemic was, in many ways, a unique period whose impacts are still being seen and felt today. The effects of the pandemic live on in people's memories, fears, hopes, and bodies......»»
Study suggests gun-free zones do not attract mass shootings
Gun-free zones have often been blamed for making schools, malls and other public areas more attractive to shooters; however, there have been no quantitative studies examining those claims. Now, in a first of its kind study published in The Lancet Reg.....»»
Seismic echoes reveal a mysterious "donut" inside Earth"s core
About 2,890 kilometers beneath our feet lies a gigantic ball of liquid metal: our planet's core. Scientists like me use the seismic waves created by earthquakes as a kind of ultrasound to "see" the shape and structure of the core......»»
Yosemite National Park: Crews restore damaged landscape back to conditions not seen in 150 years
Yosemite National Park is famous for towering waterfalls, giant sequoia trees and massive granite cliffs. But at an out-of-the-way spot near the park's western boundary few visitors ever see, a landmark of a different type is taking shape......»»
Investigation reveals global fisheries are in far worse shape than we thought—and many have already collapsed
When fish are taken from our oceans faster than they can reproduce, their population numbers decline. This over-fishing upsets marine ecosystems. It's also bad for human populations that rely on fish for protein in their diets......»»
Examining WTO system amidst growing trade imbalances
The establishment of the World Trade Organization (WTO) in 1995 coincided with a period of substantial global economic growth, fueled by lowered tariffs and increased market access in a globalized world economy based on the promise of a rules-based g.....»»
Chemists achieve PFAS-free synthesis of fluorinated pharmaceutical and agrochemical compounds
Chemists at the University of Amsterdam have developed a method to furnish a range of molecules with a trifluoromethyl group attached to a sulfur, nitrogen or oxygen atom. Their procedure, which is published in Science, avoids the use of PFAS reagent.....»»
Public opinion of new justices affects views on entire Supreme Court
A new study finds that the extent to which U.S. adults support newly appointed justices to the Supreme Court strongly influences the extent to which they support the high court as an institution......»»
International consortium with NASA reveals hidden impact of spaceflight on gut health
Scientists have uncovered how spaceflight profoundly alters the gut microbiome, revealing previously unknown effects on host physiology that could shape the future of long-duration space missions......»»
Chiral molecule research achieves near-complete separation in quantum states
In a study titled "Near-complete chiral selection in rotational quantum states" published in Nature Communications, the Controlled Molecules Group from the Molecular Physics Department of the Fritz Haber Institute has made a significant leap forward.....»»
Study shows pollution affects the growth and behavior of aquatic organisms
Research at the University of Jyväskylä, Finland, reveals that size-based selection, as happens in fishing, may impact the stress tolerance of fish, which in turn has a significant impact on the condition and coping of fish in changing environments.....»»
We must stop evictions to end chronic homelessness, says researcher
Homelessness, a crisis that affects about 11% of Canadians in their lifetime, often begins with eviction. Once a person or family is evicted, they are set on a trajectory that can lead to chronic homelessness as they try to find affordable housing in.....»»
APT group exploits WPS Office for Windows RCE vulnerability (CVE-2024-7262)
ESET researchers discovered a remote code execution vulnerability in WPS Office for Windows (CVE-2024-7262). APT-C-60, a South Korea-aligned cyberespionage group, was exploiting it to target East Asian countries. When examining the root cause, ESET d.....»»
Cold math, hot topic: Applied theory offers new insights into sea ice thermal conductivity
A new applied mathematical theory could enhance our understanding of how sea ice affects global climate, potentially improving the accuracy of climate predictions......»»
Closing the RNA loop holds promise for more stable, effective RNA therapies
New methods to shape RNA molecules into circles could lead to more effective and long-lasting therapies, shows a study by researchers at the University of California San Diego. The advance holds promise for a range of diseases, offering a more enduri.....»»
Controlling molecular electronics with rigid, ladder-like molecules
As electronic devices continue to get smaller and smaller, physical size limitations are beginning to disrupt the trend of doubling transistor density on silicon-based microchips approximately every two years, according to Moore's law. Molecular elec.....»»
The promise of synthetic cells
For over a decade, scientists have made extraordinary progress on the long-held dream of fabricating an entire cell from nonliving molecules and materials......»»
NASA"s DART impact permanently changed the shape and orbit of asteroid moon, new study shows
When NASA's Double Asteroid Redirection Test (DART) spacecraft collided with an asteroid moon called Dimorphos in 2022, the moon was significantly deformed—creating a large crater and reshaping it so dramatically that the moon derailed from its ori.....»»
Socioeconomics found to shape children"s connection to nature more than where they live
The income and education levels of a child's environment determine their relationship to nature, not whether they live in a city or the countryside. This is the finding of a new study published in People and Nature and conducted by researchers at Lun.....»»
Ultra-sensitive photothermal microscopy technique detects single nanoparticles as small as 5 nm
The detection of individual particles and molecules has opened new horizons in analytical chemistry, cellular imaging, nanomaterials, and biomedical diagnostics. Traditional single-molecule detection methods rely heavily on fluorescence techniques, w.....»»
