Astronomers may have spotted a supermassive black hole in the early universe that formed when a gargantuan gas cloud imploded.

The black hole’s host galaxy, UHZ1, was spotted in James Webb Space Telescope (JWST) observations of galaxies in the early universe. These distant galaxies’ light has been bent and magnified by the intervening galaxy cluster Abell 2,744, bringing them into view.

Ákos Bogdán (Center for Astrophysics, Harvard & Smithsonian) and others used the Chandra X-ray Observatory to take a second look at 11 of the lensed galaxies. Based on which wavelengths the galaxies are detectable at, each of the 11 appeared to lie at a redshift greater than 9, which means they’re shining at us from the universe’s first 500 million years. The team picked up X-rays from just one galaxy, the most magnified of the bunch.

Discussion with Joscha Bach and Yulia Sandamirskaya, both Intel, at the Festival of the Future 2022 by 1E9 and Deutsches Museum.

When cognitive computing meets neuromorphic computing: In their indepth dialogue at the Festival of the Future Joscha Bach, Principal AI Engineer at Intel, and his colleague Yulia Sandamirskaya, who works as a Research Scientist at Intel in Munich approach the new era of AI from two fascinatingly different angles.

Joscha Bach / Principal AI Engineer, Cognitive Computing, Intel Labs.
Joscha Bach, PhD, is a cognitive scientist and AI researcher with a focus on computational models of cognition. He has taught and worked in AI research at Humboldt University of Berlin, the Institute for Cognitive Science in Osnabrück, the MIT media lab, the Harvard Program for Evolutionary Dynamics and is currently a principal AI researcher at Intel Labs, California.

Imagine a person on the ground guiding an airborne drone that harnesses its energy from a laser beam, eliminating the need for carrying a bulky onboard battery.

That is the vision of a group of CU Boulder scientists from the Hayward Research Group. In a new study, the Department of Chemical and Biological Engineering researchers have developed a novel and resilient photomechanical material that can transform light energy into mechanical work without heat or electricity, offering innovative possibilities for energy-efficient, wireless and remotely controlled systems. Its wide-ranging potential spans across diverse industries, including robotics, aerospace and biomedical devices.

In a new study published in Nature Materials, the Hayward Research Group has developed a novel and resilient photomechanical material that can transform light energy into mechanical work without heat or electricity. The photomechanical materials offer a promising alternative to electrically-wired actuators, with the potential to wirelessly control or power robots or vehicles, such as powering a drone with a laser beam instead of a bulky on-board battery.

Adeel Razi, a computational neuroscientist at Monash University and a fellow at the Canadian Institute for Advanced Research (CIFAR) who was not involved in the new paper, says that is a valuable step. “We’re all starting the discussion rather than coming up with answers.”

Until recently, machine consciousness was the stuff of science fiction movies such as Ex Machina. “When Blake Lemoine was fired from Google after being convinced by LaMDA, that marked a change,” Long says. “If AIs can give the impression of consciousness, that makes it an urgent priority for scientists and philosophers to weigh in.” Long and philosopher Patrick Butlin of the University of Oxford’s Future of Humanity Institute organized two workshops on how to test for sentience in AI.

For one collaborator, computational neuroscientist Megan Peters at the University of California, Irvine, the issue has a moral dimension. “How do we treat an AI based on its probability of consciousness? Personally this is part of what compels me.”

Step forward platelet factor 4 (PF4): this substance in the blood has been linked to the mental boost we get from exercise, the benefits of blood transfusions, and a protein associated with longevity, in three separate studies.

All three processes promote cognitive enhancement, meaning PF4 is something of a superpowered blood factor. The research was carried out by two teams from the University of California San Francisco (UCSF) in the US and the University of Queensland in Australia.

Platelets are cell fragments that play a critical role in the clotting process. Aside from serving as physical plugs that staunch bleeding, these small, non-nucleated chunks of bone marrow cell contain granules that release chemicals to promote aggregation.

The popularity of remote food delivery skyrocketed during the COVID-19 pandemic, and the trend has continued to help businesses thrive years later. Unfortunately, some of the robotic delivery vehicles are taking a beating, with several viral videos showing people kicking the autonomous bots over and even stealing the products inside.

India’s Chandrayaan-3 spacecraft is swooping toward the moon’s surface ahead of its historic landing attempt, and it’s capturing some stunning visuals on the way.

The Indian Space Research Organization confirmed Tuesday that Chandrayaan-3 is on schedule and “smooth sailing is continuing.” The spacecraft is set to begin its final descent toward the moon’s surface on Wednesday at 5:45 p.m. IST (8:15 a.m. ET).

If successful, this mission will mark the very first soft landing on the lunar surface by an Indian spacecraft and make India the fourth country ever to accomplish such a feat. Currently, the United States, China and the former Soviet Union are the only nations that have conducted controlled landings of spacecraft on the moon.
