Astronomers have revealed new details about how young stars shape their galactic surroundings in a new study. Researchers analyzed about 18,000 star-forming regions in nearby spiral galaxies using data from powerful instruments like the James Webb Space Telescope, Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array, whose observations were made as part of the PHANGS survey—a collaboration aimed at better understanding galactic evolution.

They found that in normal galaxies, pressure from ionized gas drives the expansion of young star-forming regions...

Chronic stress, the prolonged exposure to psychological and/or physical strain, is known to be a risk factor for depression, anxiety and some other psychiatric disorders. Past studies suggest that chronic stress disrupts the integrity of myelin, a fatty insulating layer that surrounds nerve fibers and helps electrical signals travel efficiently between brain cells.

Identifying lifestyle changes that can reverse or diminish the adverse effects of chronic stress on the brain could be advantageous, as they could potentially help prevent or delay the onset of various psychiatric conditions...

Cleveland Clinic researchers are unlocking quantum computing’s full potential through the creation of a new computing paradigm inspired by the human brain. Fabio Cumbo, Ph.D., research associate in the lab of Daniel Blankenberg, Ph.D., associate staff, Computational Life Sciences, is developing the model, called quantum hyperdimensional computing (QHDC).

Cumbo published the first-ever implementation of QHDC in two distinct experiments in npj Unconventional Computing.

Hyperdimensional computing (HDC) is a type of computing based in neuroscience. It follows the idea that a concept in the brain is not stored on one single neuron...

Astronomers have detected one of the most powerful ultrafast outflows ever seen from a distant supermassive black hole. Using XMM-Newton and NuSTAR, a team studied a hyper-luminous quasar at cosmic noon and found two distinct wind components blasting away from the black hole, details of which are outlined in a paper submitted to the arXiv preprint server on June 3. The study has been submitted to the journal Astronomy & Astrophysics and is currently under minor revision.

Killer winds
Black holes consuming large amounts of material tend to lash out, driving powerful winds of gas outward from the vicinity of the accretion disk...
