Gold nanoparticles that selectively emit left- or right-handed light
When chiral gold nanoparticles are irradiated with near-infrared femtosecond pulses, visible emission of luminescence is observed. In a study published in Advanced Optical Materials, this luminescence was found to yield high selectivity for left- or.....»»
HomeKit Weekly: Govee Outdoor Wall Light delivers 1500 lumens with support for HomeKit over Matter
Permanent outdoor lighting can absolutely transition a bland space into an exciting one. Govee recently released its new which offers 1500 lumens of brightness, plenty of color options, and HomeKit support over Matter. Read on to learn more about Go.....»»
Ariane 6 launches LIFI: Light-speed secure communications
Europe's newest rocket soon launches, taking with it many space missions each with a unique objective, destination and team at home, cheering them on. Whether launching new satellites to look back and study Earth, peer out to deep space or test impor.....»»
Researchers achieve high quantum yield in photocatalytic water splitting
In photocatalytic water splitting, a photocatalyst, typically a semiconductor material, is used to absorb light energy and initiate the water splitting reaction. When light is absorbed by the photocatalyst, it creates electron-hole pairs. The excited.....»»
New method for generating monochromatic light in storage rings
When ultrafast electrons are deflected, they emit light—synchrotron radiation. This is used in so-called storage rings in which magnets force the particles onto a closed path. This light is longitudinally incoherent and consists of a broad spectrum.....»»
Boeing’s Starliner Leaves Astronauts Stuck but Safe in Space
On its first crewed flight, troubling technical glitches with Boeing’s Starliner spacecraft have left two astronauts in limbo onboard the International Space Station.....»»

Simulating blood flow dynamics for improved nanoparticle drug delivery
Despite gaining a bad rap in mainstream media in recent years, nanoparticles have been successfully used for decades in targeted drug delivery systems. Drug molecules can be encapsulated within biodegradable nanoparticles to be delivered to specific.....»»
Under pressure: How comb jellies have adapted to life at the bottom of the ocean
The bottom of the ocean is not hospitable. There is no light; the temperature is freezing cold; and the pressure of all the water above will literally crush you. The animals that live at this depth have developed biophysical adaptations that allow th.....»»
Gold nanoparticles kill cancer—but not as thought
Gold particles of the size of billionths of a meter are lethal to cancer cells. This fact has been known for a long time, as has a simple correlation: The smaller the nanoparticles used to fight the cancer cells, the faster they die. However, a more.....»»
Alphabet soup: NASA"s GOLD mission finds surprising C, X shapes in atmosphere
Who knew Earth's upper atmosphere was like alphabet soup? NASA's Global-scale Observations of the Limb and Disk (GOLD) mission has revealed unexpected C- and X-shaped formations in an electrified layer of gas high above our heads called the ionospher.....»»
Gravitational wave researchers cast new light on Antikythera mechanism mystery
Techniques developed to analyze the ripples in spacetime detected by one of the 21st century's most sensitive pieces of scientific equipment have helped cast new light on the function of the oldest known analog computer......»»
Will GTA 6 be on PC?
We're all counting the days until we can play GTA 6, but will PC players be left out of the party like always? Here's what we know about GTA 6 coming to PC......»»
Identity verification company AU10TIX – used by tech giants – left photo IDs exposed
If there’s one type of company you definitely don’t want to see left vulnerable to hackers it’s an identity verification service with access to photo ID documents like driver’s licenses – but that’s exactly what appears to have happened w.....»»
Scales helped reptiles conquer the land—when did they first evolve?
