Using the NASA X-ray spacecraft Swift combined with radio observations, astronomers have observed a supermassive black hole burping radio jets 300 days after a heavy cosmic meal. The team was also able to roughly estimate the mass of this feeding cosmic titan, which sits at the heart of the Perseus Cluster, a massive collection of thousands of galaxies. The black hole sits at the center of the galaxy NGC 1275, located around 225 light-years away, and is the brightest galaxy of the Perseus Cluster . The supermassive black hole first flared in X-rays, which indicated an increase in the rate at which it was accreting matter. Actively feeding supermassive black holes sit in regions called active galactic nuclei (AGNs), with their immense gravity heating surrounding matter, causing them to glow brightly. These emissions are boosted by material channeled to the poles of the central black hole, from w...

NASA is asking for ideas to stop static electricity from zapping astronauts or critical hardware during moon missions. The agency opened a "Lunar Grounding Challenge" to avoid situations where an astronaut on the moon could become "a walking, high voltage capacitor." Submissions for the $150,000 competition are due Jan. 15 and you can see the requirements here . NASA is hoping to put astronaut boots at the lunar south pole in 2028 during the Artemis 4 or 5 missions, on the first landing mission since NASA's Apollo 17 in 1972. But simulations suggest that both "tribocharging" (electric-charge transfer between two objects) and plasma charging (from ambient gas in the region) could build up electric charge on spacesuits. "This problem is severely compounded when entering lunar shadows and permanently shadowed regions," the agency wrote, referring to deep...

Researchers discovered a hidden factor that can determine whether chemical reactions succeed or fail, and then used it to boost the proportion of the desired product from 16% to 97%. By controlling acidity near electrodes, they developed a promising way to manufacture chemicals for plastics, medicines, and other products using oxygen and electricity instead of hazardous added oxidants. from Latest Science News -- ScienceDaily https://ift.tt/XKEOl29

A large study suggests loneliness and social isolation can cost people years of healthy life, especially when it comes to mental health. Men experiencing both lost about 5.8 years free from depression and anxiety, while women lost roughly 3.7 years. from Latest Science News -- ScienceDaily https://ift.tt/t6FOR2q

Nearly a century after physicist Hans Bethe predicted them, scientists have created and directly observed unusual quantum states known as “Bethe strings” in an ultracold gas. By cooling cesium atoms to near absolute zero and trapping them in thousands of tiny one-dimensional tubes, researchers were able to make groups of atoms bind together without ordinary chemical bonds. These strange clusters could contain six or more particles and even collide with one another without falling apart. from Latest Science News -- ScienceDaily https://ift.tt/tYGcNBP

A Stanford-designed molecule turns a major lymphoma-promoting protein against cancer cells, activating their own self-destruct machinery instead of simply blocking tumor growth. In mice, the treatment completely eliminated aggressive human lymphoma tumors within 11 days, although much more testing is needed before it could reach patients. from Latest Science News -- ScienceDaily https://ift.tt/NAi6nto
