How to thermally cloak an object
Can you feel the heat? To a thermal camera, which measures infrared radiation, the heat that we can feel is visible, like the heat of a traveler in an airport with a fever or the cold of a leaky window or door in the winter......»»
How a futuristic material is able to change its properties from soft to rigid, and back again
In our everyday life, we are surrounded by objects that have properties enabling them to perform certain functions. Rigidity and softness enable an object to perform a specific function. These properties are seemingly opposing in nature, and one prop.....»»
Promising interlayer sensitization strategy for the construction of high-performance blue hyperfluorescence OLEDs
Multi-resonance thermally activated delayed fluorescence (MR-TADF) materials are promising candidates for organic light-emitting diodes (OLEDs) with narrow electroluminescence (EL) spectra. Scientists in China propose an interlayer sensitization stra.....»»
Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effect
Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up the material very rapidly,.....»»
iOS 18 Freeform app getting giant navigation & object positioning upgrades
In iOS 18 and macOS 15, Apple's Freeform app will receive an entirely new navigation feature called Scenes, as well as new options for object alignment. Here's what to expect.Freeform will receive a new navigation feature called Scenes with iOS 18 an.....»»
New approach uses "cloaked" proteins to deliver cancer-killing therapeutics into cells
An interdisciplinary collaboration has designed a way to "cloak" proteins so that they can be captured by lipid nanoparticles, which are akin to tiny bubbles of fat. These bubbles are small enough to sneak their hidden cargo into living cells, where.....»»
Researchers develop high-performance blue organic LEDs based on thermally activated delayed fluorescence material
Organic light-emitting diodes (OLEDs) have become a leading display technology. The luminescent material is a core component of OLEDs. Thermally activated delayed fluorescence (TADF) materials have emerged as promising emitters for achieving high-eff.....»»
New nanostrings can vibrate longer than any previously known solid-state object
Researchers from TU Delft and Brown University have engineered string-like resonators capable of vibrating longer at ambient temperature than any previously known solid-state object—approaching what is currently only achievable near absolute zero t.....»»
A model outlining the microscopic origin of black hole entropy
Black holes are intriguing astronomical objects that have a gravitational pull so strong that it prevents any object and even light from escaping. While black holes have been the topic of numerous astrophysical studies, their origins and underlying p.....»»
Hubble Space Telescope glimpses spiral galaxy UGC 9684
The celestial object showcased in this image from the NASA/ESA Hubble Space Telescope is the spiral galaxy UGC 9684, which lies around 240 million light-years from Earth in the constellation Boötes. This image shows an impressive example of several.....»»
A nebula that extends its hand into space
The Gum Nebula is an emission nebula almost 1400 light-years away. It's home to an object known as "God's Hand" among the faithful. The rest of us call it CG 4......»»
Researchers unveil single-shot and complete polarization imaging system using metasurfaces
Think of all the information we get based on how an object interacts with wavelengths of light—aka color. Color can tell us if food is safe to eat or if a piece of metal is hot. Color is an important diagnostic tool in medicine, helping practitione.....»»
I compared Google and Samsung’s AI photo-editing tools. It’s not even close
Google and Samsung both have their own versions of an object removal tool. But which one works better? We found out......»»
Merging nuclear physics experiments and astronomical observations to advance equation-of-state research
For most stars, neutron stars and black holes are their final resting places. When a supergiant star runs out of fuel, it expands and then rapidly collapses on itself. This act creates a neutron star—an object denser than our sun crammed into a spa.....»»
First curved data link side-steps key 6G wireless challenge
Next-generation wireless signals will no longer emanate indiscriminately from a base station as is the case now but will likely take the form of targeted directional beams. However, any physical interference—an object or a person passing nearby, fo.....»»
Gurucul federated search provides insights into data that is not centralized
Gurucul announced enhancements to its federated search capabilities. Gurucul federated search empowers users to run queries from a single console across any data source, including data lakes, cloud object storage, databases, identity systems, threat.....»»
A chunk of metal that tore through a Florida home definitely came from the ISS
"I don't think I've seen or heard, after my own research, any of these events occurring." NASA has confirmed that the object that fell into a Florida home last month was part of a battery pack released from the International Space St.....»»
The rising flood of space junk is a risk to us on Earth—and governments are on the hook
A piece of space junk recently crashed through the roof and floor of a man's home in Florida. Nasa later confirmed that the object had come from unwanted hardware released from the international space station......»»
