Black holes are stronger than thought – magnetic fields reach deeper into galaxies

Black holes are stronger than thought – magnetic fields reach deeper into galaxies

Artist’s conception of Cygnus A, surrounded by a ring of dust and debris with jets shooting out from its center. Magnetic fields trapping dust near the supermassive black hole at the galaxy’s core are illustrated. This initial study spurred a larger comparison of radio loudness with polarization and was included in the composite dataset. Credit: …

We just got the most detailed view of an exoplanet’s atmosphere yet – and it’s active

We just got the most detailed view of an exoplanet’s atmosphere yet – and it’s active

WASP-39b, a gas giant about 700 light-years away, turned out to be an exoplanet treasure. Earlier this year, WASP-39b was the subject of the first-ever detection of carbon dioxide in the atmosphere of a planet outside the solar system. Now, in-depth analysis of data from the James Webb Space Telescope (JWST) has given us an …

Evidence for contributions of the Higgs boson to the production of Z boson pairs at high energies

Left: two-parameter probability scans of the output signal strength parameters gg and EW outside the shell, ๐œ‡off-shellF and ๐œ‡off-shellV, respectively. The dashed and dashed lines surround 68% (โˆ’2ฮ”ln๐ฟ = 2.30) and 95% (โˆ’2ฮ”ln๐ฟ = 5.99) CL regions. The intersection indicates the lower bound, and the blue diamonds represent the SM projections. The integrated brightness only …

‘Zombie’ virus rebounds after 50,000 years trapped in Siberian permafrost | Globalnews.ca

Researchers from France’s National Center for Scientific Research have successfully resurrected more than a dozen prehistoric viruses previously trapped deep in Siberian permafrost, according to a preprint study. From seven ancient permafrost samples, scientists were able to document 13 never-before-seen viruses that had been dormant, frozen in ice, over tens of thousands of years. In …

Diving Physics

Another unit is the bar, where 1 bar equals 14.5 psi. A value of 1 bar is very close to the air pressure on Earth. The atmospheric pressure of the air around you is now likely to be 14.5 psi. (Yes, I said “most likely” because I don’t want to judge you. You’re probably reading …

What if the dinosaurs did not become extinct? Why our world might look so different

Dinosaurs and giant mammals through time. Credit: Nick Longrich Sixty-six million years ago, an asteroid struck Earth with the force of 10 billion atomic bombs and changed the course of evolution. The sky darkened and plants stopped photosynthesizing. The plants died, and then the animals that fed on them died. The food chain collapsed. More …

MIT finds indoor humidity a “good spot” for reducing the spread of COVID-19

An MIT study shows that keeping indoor humidity in a good place may reduce the spread of COVID-19. New research links very dry and very humid indoor environments with the worst COVID-19 First identified in 2019 in Wuhan, China, COVID-19, or coronavirus disease 2019, (which was originally called “2019 novel coronavirus” or 2019-nCoV) is an …

Octopus brains have evolved to share a surprising feature with our brains

EMBARGO Friday November 25 1900 GMT | Saturday 26 November 0600 AEST Our gorgeous little blue marble of a planet is filled with an astonishingly diverse array of life forms, but some are certainly more exotic than others. This is especially true of the octopus, an animal so bizarre that it regularly invites comparisons to …
