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......»»
All is quiet among newly studied Centaurs
Often, the squeaky wheel, or at least the shiniest object, seems to get all the attention. In a new study led by PSI Research Scientist Eva Lilly, it is the inactive Centaurs that take center stage and illuminate why other Centaurs may be so flashy......»»
Protecting coral reefs more effectively from climate change
Thermally tolerant corals have different mechanisms for responding to heat stress. This is the conclusion of a current study by an international team of researchers including the Konstanz biologist Professor Christian Voolstra that was published in M.....»»
Researchers show that orangutans do not need to be taught how to use a hammer
Using an object to crack nuts is considered one of the most complex tool-using behaviors in the animal kingdom. So far, only chimpanzees, capuchins and macaques have been observed cracking nuts with such tools in the wild. In a new study, Dr. Elisa B.....»»
Releasing the heat: A new model to streamline the design of thermally efficient electrical contacts
When we think of modern technology in our daily lives, phones, tablets, and laptops, immediately come to mind. Using these electronic devices for extended periods of time leads to a familiar problem–overheating. As electronics have gotten smaller,.....»»
Observatory in Chile takes highest-resolution measurements of asteroid surface temperatures ever obtained from earth
A close examination of the millimeter-wavelength emissions from the asteroid Psyche, which NASA intends to visit in 2026, has produced the first temperature map of the object, providing new insight into its surface properties. The findings, described.....»»
How we see better by "looking away"
When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. This is shown in a recent study conducted at the Univ.....»»
Discovery of very red bodies in the asteroid belt that resemble trans-Neptunian objects
Two asteroids (203 Pompeja and 269 Justitia) have been discovered with a redder spectrum than any other object in the asteroid belt between Mars and Jupiter. The discovery was led by HASEGAWA Sunao, Associate Senior Researcher at ISAS JAXA, with an i.....»»
An effective strategy for protecting skyrmions in quantum computing devices
A magnetic skyrmion is a versatile topological object that can be used to carry information in future spintronic information processing devices. As potential non-volatile information carriers, excellent endurance and robust retention are desired prop.....»»
An X-ray vision-like camera to rapidly retrieve 3D images
It's not exactly X-ray vision, but it's close. In research published in the journal Optica, University of California, Irvine researchers describe a new type of camera technology that, when aimed at an object, can rapidly retrieve 3D images, displayin.....»»
A rock with many perspectives
The Alum Shale of Northern Europe not only has an eventful history of formation, connected with the microcontinent Baltica, it also holds great potential as an object of investigation for future research questions. Geologists use the rock to reconstr.....»»
New X-ray pulsar discovered
Using ART-XC and eROSITA telescopes onboard the Spectrum Roentgen Gamma (SRG) mission, an international team of astronomers has detected a new pulsar. The newly found object, designated SRGA J204318.2+443815, turns out to be a long-period, faint X-ra.....»»
Activity discovered on largest comet ever found
A newly discovered visitor to the outer edges of our solar system has been shown to be the largest known comet ever, thanks to the rapid response telescopes of Las Cumbres Observatory. The object, which is named Comet C/2014 UN271 Bernardinelli-Berns.....»»
Watching the Milky Way"s supermassive black hole feed
The supermassive black hole at the center of our Milky Way galaxy, Sagittarius A*, is by far the closest such object to us, about 27,000 light-years away. Although it is not nearly so active or luminous as other galactic nuclei with supermassive blac.....»»
What is lidar technology, and what can it do?
Lidar's distance and object sensing capabilities make it popular in technical fields, but the technology is growing much closer to home: Here's what to know......»»
A small satellite with a solar sail could catch up with an interstellar object
When 'Oumuamua, the first interstellar object ever observed passing through the solar system, was discovered in 2017, it exhibited some unexpected properties that left astronomers scratching their heads. Its elongated shape, lack of a coma, and the f.....»»
Benjamin Franklin"s fight against a deadly virus when colonial America was divided over smallpox inoculation
Exactly 300 years ago, in 1721, Benjamin Franklin and his fellow American colonists faced a deadly smallpox outbreak. Their varying responses constitute an eerily prescient object lesson for today's world, similarly devastated by a virus and divided.....»»
Astronomers Thrill at Giant Comet Flying into Our Solar System
The huge object may be the biggest comet ever seen. And it is already showing signs of activity as it approaches the orbit of Saturn -- Read more on ScientificAmerican.com.....»»
Evidence on UFOs "largely inconclusive": US intelligence report
A highly awaited US intelligence report on dozens of mysterious unidentified flying object sightings said most could not be explained, but did not rule out that some could be alien spacecraft......»»
Samsung"s Jet Bot AI+ robot vacuum is now available to pre-order for $1,299
