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......»»
NASA"s Psyche Mission Launches to Mysterious Metallic Asteroid
NASA’s Psyche mission is on its way to a heavy-metal asteroid of the same name—a type of object that scientists have never seen up close before.....»»
Five things to know about NASA"s mission to a metal world
For the first time ever, a NASA probe is set to journey to an object composed not of rock, ice, or gas, but metal: the asteroid Psyche......»»
Study suggests large mound structures on Kuiper belt object Arrokoth may have common origin
A new study led by Southwest Research Institute (SwRI) Planetary Scientist and Associate Vice President Dr. Alan Stern posits that the large, approximately 5-kilometer-long mounds that dominate the appearance of the larger lobe of the pristine Kuiper.....»»
JWST discovers massive and compact quiescent galaxy
Astronomers have reported the discovery of a new galaxy using the James Webb Space Telescope (JWST) as part of the JWST COSMOS-Web survey. The newfound object, designated JWST-ER1 is a massive and compact quiescent galaxy. The findings were detailed.....»»
Hubble peers at peculiar Arp 107 pair
This image taken using the NASA/ESA Hubble Space Telescope's Advanced Camera for Surveys (ACS) shows Arp 107, a celestial object that includes a pair of galaxies in the midst of a collision. The larger object (left) is an extremely energetic type of.....»»
Parker Probe"s path through solar blast yields unparalleled space weather insights
NASA's Parker Solar Probe has racked up an impressive list of superlatives in its first five years of operations: It's the closest spacecraft to the sun, the fastest human-made object and the first mission to ever "touch the sun.".....»»
Don’t throw out those used coffee grounds—use them for 3D printing instead
Any object you create can be thrown back into a coffee grinder and reused on a new object. Enlarge / A pendant, espresso cups, and flower planters 3D-printed from used coffee grounds. (credit: Michael Rivera) Most coffee.....»»
New faint ultra-diffuse dwarf galaxy discovered
An international team of astronomers reports the detection of a new faint ultra-diffuse dwarf galaxy as part of a systematic wide-area search for faint dwarf galaxies using the Dark Energy Survey (DES). The newfound object, designated NGC 55-dw1, is.....»»
PostgreSQL 16: Where enhanced security meets high performance
PostgreSQL is an open-source object-relational database platform with a track record of over 25 years of ongoing development. Its reputation is solid for its reliability, extensive features, and high performance. PostgreSQL 16 enhances its performanc.....»»
Experimental quantum imaging distillation with undetected light
It is possible to image an object with an induced coherence effect by making use of photon pairs to gain information on the item of interest—without detecting the light probing it. While one photon illuminates the object, its partner alone is detec.....»»
"Monstrous births" and the making of race in the nineteenth-century United States
From the Middle Ages to the Enlightenment, "monstrous births"—malformed or anomalous fetuses—were, to Western medicine, an object of superstition. In 19th-century America, they became instead an object of the "modern scientific study of monstrosi.....»»
Striking gold with molecular mystery solution for potential clean energy
Hydrogen spillover is exactly what it sounds like. Small metal nanoparticles anchored on a thermally stable oxide, like silica, comprise a major class of catalysts, which are substances used to accelerate chemical reactions without being consumed the.....»»
DART Showed How to Smash an Asteroid. So Where Did the Space Shrapnel Go?
Last year’s NASA mission proved it was possible to knock an incoming near-Earth object off course. But that creates debris—which might also be a threat......»»
NASA"s New Horizons mission still threatened
The New Horizons spacecraft that studied Pluto and Kuiper belt object Arrokoth continues its pioneering exploration of the Kuiper belt. However, that might soon end if NASA doesn't change course. The New Horizons science team has been told by NASA th.....»»
How to Cool an Object Without Using Any Energy
It seems impossible, but there’s a way to cool things off without tapping into a fuel source. (Hint: It involves outer space.).....»»
Fluid dynamics researchers shed light on how partially submerged objects experience drag
One of the most common and practically useful experiments in all of fluid dynamics involves holding an object in air or submerging it fully underwater, exposing it to a steady flow to measure its resistance in the form of drag. Studies on drag resist.....»»
Future Apple Watch could color-coordinate itself automatically
Apple may never allow us to create whole Apple Watch faces ourselves, but it is looking at how you could show the Watch a band, or any object, and have it adapt to its color.For eight years, users — or at least third-party firms — have wanted the.....»»
How extraterrestrial tales of aliens gain traction
One night, upon returning to the cave that his tribe calls home, the monkey-humanoid Moon-Watcher finds a strange crystal object, a kind of monolith that fascinates him at first, but then quickly loses his interest when he discovers that it is not ed.....»»
Thermally induced orderly alignment of porphyrin photoactive motifs in metal-organic frameworks
Professor Shi Weiqun's group from the Institute of High Energy Physics of the Chinese Academy of Sciences has made progress in the application of metal-organic frameworks (MOFs) in the field of photocatalytic CO2 reduction. The study was published in.....»»
Object recognition through vision, hearing and touch—it"s time to let go of the learning styles myth
The idea that individual people are visual, auditory or kinesthetic learners and learn better if instructed according to these learning styles is one of the most enduring neuroscience myths in education......»»
