Ultrafast electron imaging captures never-before-seen nuclear motions in hydrocarbon molecules excited by light
The interactions between light and nitroaromatic hydrocarbon molecules have important implications for chemical processes in our atmosphere that can lead to smog and pollution. However, changes in molecular geometry due to interactions with light can.....»»
Chemists find alkyl groups are electron-withdrawing, challenging a century-old belief
Scientists are calling for changes to chemistry textbooks after discovering a fundamental aspect of structural organic chemistry has been incorrectly described for almost 100 years......»»
Microsoft Recall now available in beta – and I believe Apple could do it the right way
Microsoft this year teased a new feature for Windows called “Microsoft Recall,” which essentially captures snapshots of everything that happens on the PC and uses AI to let users quickly find something they’ve forgotten. After much controversy,.....»»
Effects of extreme weather events on soil microbes shed light on climate change risks
New research has revealed how tiny soil microbes are impacted by extreme weather events, offering new insights into the risks posed by climate change......»»
Cell model identifies important factor in neural development
The Wistar Institute's Alessandro Gardini, Ph.D., and lab have shed new light on how certain biological processes determine the development of neural cells. Their findings on a molecular "bridge" complex demonstrate a new level of detail in the under.....»»
Report highlights urgent need for age-appropriate housing solutions
A new report from the government-appointed Older People's Housing Taskforce has shed light on the critical shortage of suitable housing options for senior citizens......»»
Same plant, different tactic: Habitat determines response to climate, thale cress study finds
Plants need light to grow, but too much light can induce damage to the photosynthetic complex known as photosystem II. It is known that plants adapted to growing under full sun repair this light-induced damage more. But this repair activity slows dow.....»»

A team of researchers led by Anna-Karin Gustavsson at Rice University has developed an innovative imaging platform that promises to improve our understanding of cellular structures at the nanoscale......»»
Why an Offline Nuclear Reactor Led to Thousands of Hospital Appointments Being Canceled
Radioisotopes are a vital resource for imaging patients’ organs and tumors—but these unstable elements also suffer from an unstable supply chain......»»
Bandwidth measurements show how pulsar signals distort as they move through space
A study that sheds new light on how pulsar signals—the spinning remnants of massive stars—distort as they travel through space, published in The Astrophysical Journal, was led by Dr. Sofia Sheikh, SETI Institute researcher, and performed by a mul.....»»
Benchmarking the Continuous Electron Beam Accelerator Facility
It's a paper that's been more than four decades in the making. Published in Physical Review Accelerators and Beams, a study has re-benchmarked the main particle accelerator at the U.S. Department of Energy's Thomas Jefferson National Accelerator Faci.....»»
Magnetically driven vortices may be generating Earth-size concentrations of hydrocarbon haze at Jupiter"s poles
While Jupiter's Great Red Spot has been a constant feature of the planet for centuries, University of California, Berkeley, astronomers have discovered equally large spots at the planet's north and south poles that appear and disappear seemingly at r.....»»
Researchers develop light-guided siRNA delivery system based on cyanobacteria
In a study published in Cell Reports Physical Science on Nov. 25, a research team reported the development of an innovative intelligent light-guided biohybrid system, the CTPA/siCSF1R system, to target tumor-associated macrophages (TAMs), thus enabli.....»»

Sombrero Galaxy dazzles in new Webb images and video
A new mid-infrared image from the NASA/ESA/CSA James Webb Space Telescope features the Sombrero galaxy, also known as Messier 104 (M104). The signature, glowing core seen in visible-light images does not shine, and instead a smooth inner disk is reve.....»»
Spin-powered crystals dramatically improve water splitting process for clean hydrogen production
Water splitting—breaking water molecules into hydrogen and oxygen—is a promising pathway to sustainable energy. However, this process has long been challenged by the slow chemical kinetics of the oxygen evolution reaction that make hydrogen produ.....»»
Why some countries are more likely to believe nuclear war won"t happen to them
The war in Ukraine has just edged up another notch. It has not been going well for Ukraine in recent months, and this week Joe Biden's administration made the decision to allow Ukraine to fire US-supplied army tactical missile systems (Atacms) long-r.....»»
Brighter and more efficient LEDs with low polarization resist "efficiency droop"
Light-emitting diodes (LEDs) are everywhere in modern life, from smartphones to home lighting. But today's LEDs have a major limitation: when you try to make them brighter by increasing their power, they become less efficient......»»
WEAVE spectrograph uncovers dual nature of galaxy shock
Using the set of first-light observations from the new William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE) wide-field spectrograph, a team of more than 50 astronomers, led by Dr. Marina Arnaudova at the University of Hertfordshire, has.....»»
Accessing the lesser known nucleon: New neutron measurement can help physicists learn about nucleon structure and spin
Protons and neutrons–known collectively as nucleons–are both the building blocks of matter, but one of these particles has received a bit more attention in certain types of nuclear physics experiments......»»
