Furthest ever detection of a galaxy's magnetic field      (via sciencedaily.com) 

Astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides astronomers with vital clues about how the magnetic fields of galaxies like our own Milky Way came to be.

Care robots: Ethical perceptions and acceptance      (via sciencedaily.com) 

The global population of people older than 65 years of age is rapidly increasing the need for care. Although care robots are a promising solution to fill in for caregivers, their social implementation has been slow and unsatisfactory. A team of international researchers has now developed the first universal model that can be employed across cultural contexts to explain how ethical perceptions affect the willingness to use care robots.

How a cup of water can unlock the secrets of our Universe      (via sciencedaily.com)     Original source 

A researcher made a discovery that could change our understanding of the universe. He reveals that there is a range in which fundamental constants can vary, allowing for the viscosity needed for life processes to occur within and between living cells. This is an important piece of the puzzle in determining where these constants come from and how they impact life as we know it.

New type of star gives clues to mysterious origin of magnetars      (via sciencedaily.com)     Original source 

Magnetars are the strongest magnets in the Universe. These super-dense dead stars with ultra-strong magnetic fields can be found all over our galaxy but astronomers don't know exactly how they form. Now, using multiple telescopes around the world, researchers have uncovered a living star that is likely to become a magnetar. This finding marks the discovery of a new type of astronomical object -- massive magnetic helium stars -- and sheds light on the origin of magnetars.

Webb reveals colors of Earendel, most distant star ever detected      (via sciencedaily.com) 

NASA's James Webb Space Telescope has followed up on observations by the Hubble Space Telescope of the farthest star ever detected in the very distant universe, within the first billion years after the big bang. Webb's NIRCam (Near-Infrared Camera) instrument reveals the star to be a massive B-type star more than twice as hot as our Sun, and about a million times more luminous.

AI transformation of medicine: Why doctors are not prepared      (via sciencedaily.com) 

The success of artificial intelligence technologies depends largely on how physicians interpret and act upon a tool's risk predictions -- and that requires a unique set of skills that many are currently lacking, according to a new perspective article.

How good is that AI-penned radiology report?      (via sciencedaily.com) 

New study identifies concerning gaps between how human radiologists score the accuracy of AI-generated radiology reports and how automated systems score them. Researchers designed two novel scoring systems that outperform current automated systems that evaluate the accuracy of AI narrative reports. Reliable scoring systems that accurately gauge the performance of AI models are critical for ensuring that AI continues to improve and that clinicians can trust them.

Gravitational arcs in 'El Gordo' galaxy cluster      (via sciencedaily.com) 

A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of unusual, distorted background galaxies that were only hinted at in previous Hubble Space Telescope images.

New clues on the source of the universe's magnetic fields      (via sciencedaily.com) 

Researchers offer insight into the source of cosmic magnetic fields. The research team used models to show that magnetic fields may spontaneously arise in turbulent plasma. Their simulations showed that, in addition to generating new magnetic fields, the turbulence of those plasmas can also amplify magnetic fields once they've been generated, which helps explain how magnetic fields that originate on small scales can sometimes eventually reach to stretch across vast distances.

Breakthrough in Monte Carlo computer simulations      (via sciencedaily.com) 

Researchers have developed a highly efficient method to investigate systems with long-range interactions that were previously puzzling to experts. These systems can be gases or even solid materials such as magnets whose atoms interact not only with their neighbors but also far beyond.

Galaxy J1135 reveals its water map      (via sciencedaily.com) 

Researchers look at water in galaxies, its distribution and in particular its changes of state from ice to vapor, as important markers indicating areas of increased energy, in which black holes and stars are formed. A new study has now revealed the distribution of water within the J1135 galaxy, which is 12 billion light years away and formed when the Universe was a 'teenager', 1.8 billion years after the Big Bang . This water map, with unprecedented resolution, is the first ever to be obtained for such a remote galaxy. The map can help scientists to understand the physical processes taking place within J1135 and shed light on the dynamics, still partially unclear, surrounding the formation of stars, black holes and galaxies themselves.

Efficient discovery of improved energy materials by a new AI-guided workflow      (via sciencedaily.com) 

Scientists have recently proposed a workflow that can dramatically accelerate the search for novel materials with improved properties. They demonstrated the power of the approach by identifying more than 50 strongly thermally insulating materials. These can help alleviate the ongoing energy crisis, by allowing for more efficient thermoelectric elements, i.e., devices able to convert otherwise wasted heat into useful electrical voltage.

Giant swirling waves at edge of Jupiter's magnetosphere      (via sciencedaily.com) 

A team has found that NASA's Juno spacecraft orbiting Jupiter frequently encounters giant swirling waves at the boundary between the solar wind and Jupiter's magnetosphere. The waves are an important process for transferring energy and mass from the solar wind, a stream of charged particles emitted by the Sun, to planetary space environments.
