A team of researchers led by the National Astronomical Observatory of Japan discovered unexpectedly intricate magnetic structures above quiet-sun regions by observing the sun with the balloon-borne solar observatory Sunrise-III during its 2024 flight in Earth’s stratosphere. The work is published in The Astrophysical Journal Letters.

An international research team has discovered a previously unknown mechanism that plays a key role in the signaling pathways involved in programmed cell death. The team identified the protein HERC4 as an essential component of both TNF-induced necroptosis and apoptosis pathways—two processes that play a crucial role in maintaining cellular balance and triggering inflammatory responses.

The study, “HERC4-mediated ubiquitination licenses RIPK1 to initiate TNF-induced cell death,” was published in Nature Structural and Molecular Biology. The lead researchers were Dr...

Quantum computer boldly goes where no quantum computer has gone before: Space

There’s big news from the quantum world. A quantum computer has been used in space for the first time. The device was aboard a spacecraft in low Earth orbit and demonstrated technology that could eventually help solve a problem that has been bugging satellites for years.

The issue is that when orbiting satellites send their raw data back down to Earth, bottlenecks and bandwidth limits slow everything down. One way to overcome this would be to process the raw data in situ before sending it.

So a team of physicists led by Philip Walther at the University of Vienna came up with a way that could eventually do just that...

Black hole jets reach far beyond galaxies’ visible edges, potentially deciding their fate

ASU astronomers uncover black hole jets reaching far beyond their galaxies and deciding their fate
Artist’s illustration of a supermassive black hole at the center of a radio galaxy launching powerful jets (shown in pink) all the way into the galaxy’s CGM. The study finds that these jets do not light up the surrounding gas equally in all directions. Instead, the hydrogen gas glows (shown in red) most strongly along the path of the radio jets. This suggests that black holes can send energy far beyond the galaxy’s center and shape the larger gas reservoir that regulates star formation and fate of galaxies. We use optical data from the DESI survey and radio observations from the LOFAR Two meter Sky Survey (LoTss). Credit: Hailey Nelson/ Arizona State University.

Galaxies are enormous and hold hundreds of billions of stars. These stars form from cold, dense gas...
