Distant quasar J0439+1634 explored in X-rays
Using ESA's XMM-Newton spacecraft, an international team of astronomers has conducted X-ray observations of the most distant known gravitationally lensed quasar—J0439+1634. Results of the study, published December 20 on the arXiv pre-print server,.....»»
Stephen King shares his thoughts on AI writing fiction
Stephen King has shared his thoughts on AI writing fiction, and they can probably be summed up best with the following phrase: "A certain dreadful fascination".The horror author explored the topic of artificial intelligence – a key issue in the.....»»

New research shows the way to cultivate meaningful social connections online
At first glance, the term "digital hug" might seem paradoxical. After all, how does the physical act of embracing one another have anything to do with the digital world in which we are so often physically distant, even worlds apart?.....»»
Stellantis weighs EV tie-up to expand in China, report says
The carmaker has explored potentially working with Chinese EV makers such as Zhejiang Leapmotor Technologies, sources told Bloomberg......»»
Image: Hubble captures cosmic cluster
The massive cluster Abell 3322 is featured in this image from the NASA/ESA Hubble Space Telescope, in which the galaxy 2MASX J05101744-4519179 basks in the center. This distant galaxy cluster is a cosmic leviathan that is highly luminous at X-ray wav.....»»
Complex galaxy cluster Abell 119 explored by researchers
Using NASA's Chandra spacecraft, astronomers have performed detailed X-ray observations of a complex galaxy cluster known as Abell 119. Results of the observational campaign, published August 9 on the pre-print server arXiv, shed more light on the pr.....»»
Riding a wave to better medical diagnostic imaging
Medical imaging via X-rays, CT scans, MRIs and ultrasounds provide health-care professionals with unique perspectives and a better understanding of what's happening inside a patient's body. Using various forms of waves, these machines can visualize m.....»»
James Webb captures image of the most distant star ever discovered
The James Webb Space Telescope has captured a stunning image of the most distant star ever discovered, named Earendel......»»
Webb telescope reveals colors of Earendel, most distant star ever detected
Detecting extremely distant stars, or those closest in time to the big bang, can provide insights into the first few chapters of the history of our universe. In 2022, the Hubble Space Telescope broke its own record, and spotted the most distant star.....»»
The link between the impact of radiation on DNA and the time in which the damaged molecule breaks irreversibly revealed
We are exposed to ionizing radiation more often than we think: when we bathe in the sun, which emits UV rays, or when we get X-rayed. Even when we are traveling on an intercontinental flight, which reaches 10,000 meters above sea level. This type of.....»»
Voyager 2 phones home and says everything is cool

NASA back in touch with Voyager 2 after "interstellar shout"
NASA has succeeded in re-establishing full contact with Voyager 2 by using its highest-power transmitter to send an "interstellar shout" that righted the distant probe's antenna orientation, the space agency said Friday......»»
Dinosaur track site in Lesotho: How a wrong turn led to an exciting find
I am a poor navigator. This is not an easy thing for a field geologist to admit. We need to be able to find our planned area of interest in good time and make our way back to our potentially hidden and distant vehicles at the end of the day. It's esp.....»»
Ultrasound-based microfluidic manipulation platform for airborne droplets
As science races toward automation and quick experiments, it is sometimes required to concurrently handle small amounts of liquids (droplets), from picoliters to microliters. Moreover, droplet jumping is required when transporting droplets to distant.....»»
Helium in Distant Galaxies May Help Explain Why the Universe Exists
New measurements from Japan’s Subaru telescope have helped researchers study the matter-antimatter asymmetry problem.....»»

Investigating the Ising model with magnetization
Researchers have explored the evolution of systems of interacting spins, as they transition from random to orderly alignments. Through new simulations, they show that this evolution can be investigated by measuring the changing strength of the system.....»»
Researchers use X-rays to find the best antibodies
Antibody therapies have a variety of uses, but we need to know which therapies work and which ones don't. Recent research has discovered a means to determine how effective certain antibodies can be in medical scenarios......»»
Better energy harvesting with "law-breaking" device
If you take an object and set it out in the sun, it will begin to warm up. This is because it is absorbing energy from the sun's rays and converting that energy to heat. If you leave that object outside, it will continue getting warmer, but only to a.....»»
AI-enabled portable e-nose sniffs out harmful molecules
Consider this—there is no cheap, at-home device that can tell you milk has gone bad faster than your nose. One whiff and you know that the milk has gone rancid. Humans have created technologies that allow us to see distant stars and single atoms bu.....»»
