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......»»
Researchers cool a 40 kg object to near its quantum ground state
Mirrors of the LIGO gravitational-wave detector get cool—extremely cool. Enlarge / One of the 40 kg mirrors that has approached its quantum ground state. (credit: Matt Heintze/Caltech/MIT/LIGO Lab) Objects that obey the rules of quantum.....»»
Physicists bring human-scale object to near standstill, reaching a quantum state
To the human eye, most stationary objects appear to be just that—still, and completely at rest. Yet if we were handed a quantum lens, allowing us to see objects at the scale of individual atoms, what was an apple sitting idly on our desk would appe.....»»
Bending light for safer driving; invisibility cloaks to come?
Optical cloaking allows objects to be hidden in plain sight or to become invisible by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, like in the "Harry Potter" books, researchers in recent years.....»»
Observations detect a brown dwarf orbiting the star TOI–1278
An international team of astronomers reports the discovery of a companion to the M dwarf star known as TOI–1278. The newly found object turns out to be a brown dwarf nearly 20 times as massive as Jupiter. The finding is detailed in a paper publishe.....»»
NASA is designing a space telescope to protect Earth from asteroid impacts
NASA's Near-Earth Object Surveyor space telescope would use infrared sensors to detect asteroids or comets which threaten the planet......»»
Mystery object caused by spontaneous symmetry breaking revealed
Hiromitsu Takeuchi, a lecturer at the Graduate School of Science, Osaka City University, and a researcher at the Nambu Yoichiro Institute of Theoretical and Experimental Physics (NITEP), has theoretically identified the nature of a mysterious topolog.....»»
X-ray scanner spots cancers and analyzes drugs in minutes
Engineers at Duke University have demonstrated a prototype X-ray scanning machine that reveals not just the shape of an object but its molecular composition. With unprecedented resolution and accuracy, the technology could revolutionize a wide range.....»»
Engineered virus and goggles restore object recognition in a blind man
What started out as an experimental tool has evolved into a treatment. Enlarge / The goggles in use. The red cap isn't part of the system; it holds electrodes that are tracking the participant's brain activity. (credit: Sahel et. al.) Our nerv.....»»
Unexpected Gaseous Nickel Spewing From Second Known Interstellar Object
New submitter StellarThoughts writes: Scientists analyzed the second ever known interstellar object, a comet known as 2I/Borisov, and found some very unlikely results. Molecules of nickel and iron were being vaporized and drifting from the surface. T.....»»
What mimes can teach us about visual perception
Mimes "make us feel like we’re aware of an object just by seeming to interact with it." When we watch a mime seemingly pull rope, climb steps, or try to escape that infernal box, we don't struggle to recognize the implied objects. Rather.....»»
What mimes interacting with invisible objects says about visual perception

Provenance: How an object"s origin can facilitate authentic, inclusive storytelling
Passports are a tangible way of showing where one has traveled, as the stamps provide a chronological order that traces an individual's journey across international borders. When an object's origins are not readily apparent, a variety of sources can.....»»
Improvements Finally Made in How We Name Asteroids
RockDoctor (Slashdot reader #15,477) writes: For a number of years the administrative process for giving asteroids names has had a worsening logjam. Important or "interesting" bodies (such as `Oumuamua, the first definitely interstellar object ident.....»»

Astronomers detect substellar companion of HD 47127
Using the Harlan J. Smith Telescope, astronomers have discovered that the star HD 47127 has a substellar companion. The newly identified object, designated HD 47127 B, appears to be a brown dwarf or a brown dwarf binary. The finding is reported in a.....»»

Voyager 1 Detects Plasma "Hum"
Obipale shares a report from Phys.Org: Voyager 1 -- one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space -- still works and zooms toward infinity. The craft has long since zipped past the edge o.....»»
In the emptiness of space, Voyager 1 detects plasma "hum"

Large Chinese rocket segment disintegrates over Indian Ocean
A large segment of a Chinese rocket re-entered the Earth's atmosphere and disintegrated over the Indian Ocean on Sunday, the Chinese space agency said, following fevered speculation over where the 18-tonne object would come down......»»
Material scientists find new angle toward better heat transfer
UCLA materials scientists have developed a class of optical material that controls how heat radiation is directed from an object. Similar to the way overlapping blinds direct the angle of visible light coming through a window, the breakthrough involv.....»»
