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......»»
New magnetic cataclysmic variable detected
By analyzing the data from the Spektr-RG (SRG) spacecraft and the Transiting Exoplanet Survey Satellite (TESS), astronomers have detected a new magnetic cataclysmic variable. The new object, designated SRGE J075818-612027, is most likely of the polar.....»»
Owl Autonomous Imaging uses AI to create enhanced automotive thermal imaging technology
As cars become more intelligent, ensuring better vision has been the priority, especially at night. US-based Owl Autonomous Imaging integrates thermal images with artificial intelligence to do object detection, classification and ranging for a vehicl.....»»
Revealing the embedded phase in single-pixel quantum ghost imaging
When forming an image of an object, such as a photograph taken by a cell phone, light that has interacted with the object and either passed through or bounced off it is captured by the detector in the phone......»»
"Tadpole" molecular cloud appears to be playing around black hole
A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most likely a black hole 100,000 times more massive than t.....»»
The secret lives of neutron stars
Astrophysicists use gravitational waves and light to trace genealogies of dead stars. Composite X-ray, visible-light, and radio image of the X-ray binary Circinus X-1. This object is a neutron star in mutual orbit with an ordinar.....»»
Jony Ive"s Red Nose: Unexpectedly well designed

Dwarf planet hosts a ring that’s unexpectedly far from the planet
At that distance, the ring should condense into a moon. Why hasn't it? Enlarge / Prior to this, Quaoar (lower left) looked like a very average Kuiper belt object. (credit: NASA) Many bodies in the Solar System have rings.....»»
Forspoken cloaks: all cloak locations and abilities
Cloaks may not seem like a strong armor piece, but once you see how much a good cloak can improve your abilities, you'll be glad to know how to get them all......»»
US military shoots down Chinese balloon over coastal waters
Once the object was over the ocean, US jets moved in. Enlarge (credit: Andrea Nissotti / EyeEm) On Saturday afternoon, US jets intercepted the Chinese surveillance balloon as it was leaving the continental US. Live foota.....»»
Researchers find the key to reducing drag on superhydrophobic surfaces can come down to a single parameter
Sometimes, the most complex problems can be solved with the simplest approaches. Such was the case for researchers at UC Santa Barbara as they tried to resolve a longstanding issue of fluid friction—the resistance between an object moving through f.....»»
An asteroid just came incredibly close to Earth
An asteroid just hurtled past Earth in an event described by NASA as “one of the closest approaches by a near-Earth object ever recorded.”.....»»
NASA system predicts small asteroid to pass close by Earth this week
Asteroid 2023 BU is about the size of a box truck and is predicted to make one of the closest approaches by a near-Earth object ever recorded......»»
Elio Antonio de Nebrija: From academic icon to object of mockery
Professor Lola Pons, of the Department of Spanish Language, Linguistics and Literature at the University of Seville, has just published a study of a satirical work on marriage written in the 17th century by an anonymous author. Joking about courtship.....»»
A rainbow of force-activated pigments for identifying stress
Stress isn't just the psychological pressure you feel in response to a looming deadline at work. It is also a description of the physical forces pushing, pulling, or twisting an object, structure, or material. Examples of stress include gravity dragg.....»»
RNA lipid nanoparticle engineering stops liver fibrosis in its tracks, reverses damage
Since the success of the COVID-19 vaccine, RNA therapies have been the object of increasing interest in the biotech world. These therapies work with your body to target the genetic root of diseases and infections, a promising alternative treatment me.....»»
Maximizing data value while keeping it secure
How can organizations create an environment that allows the broadest access across distributed warehouses, databases, object stores and data exchanges, while at the same time maintaining consistent data oversight? There’s no single template for.....»»
Researchers create an optical tractor beam that pulls macroscopic objects
Researchers have developed a way to use laser light to pull a macroscopic object. Although microscopic optical tractor beams have been demonstrated before, this is one of the first times that laser pulling has been used on larger objects......»»
Construction begins on NASA"s next-generation asteroid hunter
A space telescope designed to search for the hardest-to-find asteroids and comets that stray into Earth's orbital neighborhood, NASA's Near-Earth Object Surveyor (NEO Surveyor) recently passed a rigorous technical and programmatic review. Now the mis.....»»
Hubble captures dual views of an unusual star cluster
While these two images may look dazzlingly different, they are actually pictures of the same cosmic object: NGC 1850. Although the same Hubble instrument took both images, different filters with different assigned colors were used to study particular.....»»
Broken symmetries provide opportunities for thermal emission management
Radiative heat transfer is a ubiquitous physical process in our universe. Any object with a temperature above absolute zero exchanges thermal energy with the environment. In physics, thermal emission originates from electromagnetic radiation induced.....»»
