Electrons on the run: On chirality, tunneling and light fields
Will an electron escaping a molecule through a quantum tunnel behave differently depending on the left- or right-handedness of the molecule?.....»»
As the Advanced Photon Source upgrade nears completion, scientists anticipate experimental possibilities
In June, X-rays began to shine again at the U.S. Department of Energy's (DOE) Advanced Photon Source (APS), a facility where intense, directed X-ray light beams are used to inspect everything from materials for better solar cells and batteries to ant.....»»
Quantum research paves the way toward efficient, ultra-high-density optical memory storage
As our digital world generates massive amounts of data—more than 2 quintillion bytes of new content each day—yesterday's storage technologies are quickly reaching their limits. Optical memory devices, which use light to read and write data, offer.....»»
Solar Sails and Comet Tails: How Sunlight Pushes Stuff Around
It seems crazy, but light actually exerts a physical force on objects. It could power a new generation of spacecraft for deep-space missions......»»
London Standard"s AI-generated review, by late art critic Brian Sewell, exposes a significant philosophical threat

Monkey fossils found in cave shed light on the animals" extinction centuries ago
By studying rare fossils of jaws and other skull parts of a long-extinct Caribbean monkey, a team of researchers that includes a Johns Hopkins University School of Medicine professor says it has uncovered new evidence documenting the anatomy and ecol.....»»
Researchers create orientation-independent magnetic field-sensing nanotube spin qubits
Purdue University researchers have developed patent-pending one-dimensional boron nitride nanotubes (BNNTs) containing spin qubits, or spin defects. The BNNTs are more sensitive in detecting off-axis magnetic fields at high resolution than traditiona.....»»
Developing novel chiral capsule tools for advanced optical technologies
Chirality is an essential property in biology; the molecular building blocks of some of the most important biological structures, including DNA and proteins, are chiral. When a molecule is said to be chiral, it means that it is distinguishable from i.....»»
Q&A: Researchers examine link between light pollution and interest in astronomy
Picture walking outside on a dark, cloudless evening. You look up to admire the stars—maybe even a planet, if you're lucky—and a sense of wonder washes over you. New research from the University of Washington shows this might be more than a memor.....»»
Influence of a black hole"s spin: First evidence of precession in ultraluminous accretion disks
Gas swirls around a black hole due to its intense gravity, forming an accretion disk. These accretion disks, being among the most efficient energy conversion mechanisms in the universe, emit light and plasma jets. When a black hole spins on its axis,.....»»
Scientists decode brain mechanisms of stopping in Drosophila
Ever wish you could stop that fruit fly on your kitchen counter in its tracks? Scientists at Max Planck Florida Institute for Neuroscience have created flies that halt under red light. In doing so, they discovered the precise neural mechanisms involv.....»»
Q&A: Using a new approach to shine a light on hidden plant microbes
Despite there being more microbes on Earth than stars in our galaxy, only a tiny fraction have been discovered. An approach called metagenomics—a type of DNA sequencing—may help scientists learn more about these elusive organisms, according to Pe.....»»
How Android Users Can Minimize Blue Light’s Effects on Eye Health
As smartphones become increasingly essential for school, work, and daily life, individuals utilize mobile operating systems like Android for more efficient research, communication, and overall connectivity. In fact, a report reveals that Android co.....»»
Swiss glaciers are receding again after 2 punishing years and despite a good start to 2024
The volume of Switzerland's glaciers shrank again this summer, compounding the negative impact of climate change after a devastating two-year run that depleted the ice by more than 10%, scientific experts reported Tuesday......»»
The new Samsung Galaxy Chromebook Plus is crazy thin and light
Samsung has announced its latest Chromebook computer, the Chromebook Plus, which is the thinnest and lightest Chromebook Plus to date. The post The new Samsung Galaxy Chromebook Plus is crazy thin and light appeared first on Phandroid. Sam.....»»
Research highlights global plant diversity "darkspots" where scientific efforts are urgently needed
An ambitious project led by scientists from the Royal Botanic Gardens, Kew, along with global partners, seeks to shed light on the planet's "plant diversity darkspots"—regions teeming with biodiversity but where geographic and taxonomic data remain.....»»
Western media outlets are trying to fix their coverage of Africa. Is it time African media did the same?
Quick question: what do these titles have in common? A Dark Continent Seeking Light; Sure, Ebola is Bad. Africa has Worse, or; Magic and Cannibalism in the African Jungle. You guessed it—they're all about Africa. But the most correct answer is they.....»»
