Published NIRISS instrument on Webb maps an ultra-hot Jupiter's atmosphere
(via sciencedaily.com) Original source There's an intriguing exoplanet out there -- 400 light-years out there -- that is so tantalizing that astronomers have been studying it since its discovery in 2009. One orbit for WASP-18 b around its star that is slightly larger than our Sun takes just 23 hours. There is nothing like it in our Solar System. A new study about this exoplanet, an ultra-hot gas giant 10 times more massive than Jupiter.
Published Crossing the ring: New method enables C-H activation across saturated carbocycles
(via sciencedaily.com) Original source Chemists add another powerful tool to their 'molecular editing' toolkit for crafting pharmaceuticals and other valuable compounds.
Published Quest for alien signals in the heart of the Milky Way takes off
(via sciencedaily.com) Original source A graduate student is spearheading an extraordinary scientific endeavor -- a groundbreaking mission to uncover periodic signals emanating from the core of the Milky Way called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS). Such repetitive patterns could be the key to unlocking the mysteries of extraterrestrial intelligence in our galaxy.
Published Towering plume of water escaping from Saturn moon
(via sciencedaily.com) Original source Scientists have observed a towering plume of water vapor more than 6,000 miles long -- roughly the distance from the U.S. to Japan -- spewing from the surface of Saturn's moon, Enceladus.
Published Astronomers discover last three planets Kepler telescope observed before going dark
(via sciencedaily.com) Original source With the help of citizen scientists, astronomers discovered what may be the last three planets that the Kepler Space Telescope saw before it was retired.
Published Evolution driving improvements in racehorse speed
(via sciencedaily.com) Original source A new study has found that genetic improvement is underlying the increasing speed of Britain's thoroughbreds. This contrasts with earlier studies that suggested racehorses were showing no genetic improvement in response to selection by breeders.
Published One-third of galaxy's most common planets could be in habitable zone
(via sciencedaily.com) Original source A third of the exoplanets orbiting common M dwarf stars have gentle enough orbits to potentially be in the habitable zone capable of hosting liquid water.
Published X-ray emissions from black hole jets vary unexpectedly, challenging leading model of particle acceleration
(via sciencedaily.com) Original source Black hole jets are known to emit x-rays, but how they accelerate particles to this high-energy state is still a mystery. Surprising new findings appear to rule out a leading theory, opening the door to reimagining how particle acceleration works. One model of how jets generate x-rays expects the jets' x-ray emissions to remain stable over long time scales. However, the new paper found that the x-ray emissions of a statistically significant number of jets varied over just a few years.
Published Protein-based nano-'computer' evolves in ability to influence cell behavior
(via sciencedaily.com) Original source The first protein-based nano-computing agent that functions as a circuit has been created. The milestone puts them one step closer to developing next-generation cell-based therapies to treat diseases like diabetes and cancer.
Published Astronomers discover a key planetary system to understand the formation mechanism of the mysterious 'super-Earths'
(via sciencedaily.com) Original source A study presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth. This system, located 150 light-years from Earth, is one of the best candidates for a detailed study of their atmosphere with the JWST space telescope.
Published Helium nuclei research advances our understanding of cosmic ray origin and propagation
(via sciencedaily.com) Original source The latest observations from Low Earth Orbit with the International Space Station provide further evidence of spectral hardening and softening of cosmic ray particles.
Published A deep underground lab could hold key to habitability on Mars
(via sciencedaily.com) Original source Tunnels deep underground in North Yorkshire are providing a unique opportunity to study how humans might be able to live and operate on the Moon or on Mars.
Published NASA's Hubble hunts for intermediate-sized black hole close to home
(via sciencedaily.com) Original source Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the closest globular star cluster to Earth, located 6,000 light-years away.
Published Fluorine-based new drug synthesis at lightning speed
(via sciencedaily.com) Original source Researchers synthesize fluorine-based compound via rapid biphasic (gas and liquid) mixing.
Published Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world
(via sciencedaily.com) Original source Researchers found that the Hunga-Tonga eruption was associated with the formation of an equatorial plasma bubble in the ionosphere, a phenomenon associated with disruption of satellite-based communications. Their findings also suggest that a long-held atmospheric model should be revised.
Published An X-ray look at the heart of powerful quasars
(via sciencedaily.com) Original source Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner workings of quasars and how they interact with their environment.
Published Driving on sunshine: Clean, usable liquid fuels made from solar power
(via sciencedaily.com) Original source Researchers have developed a solar-powered technology that converts carbon dioxide and water into liquid fuels that can be added directly to a car's engine as drop-in fuel.
Published Watch these cells rapidly create protrusions for exploration and movement
(via sciencedaily.com) Original source In order to move, cells must be able to rapidly change shape. A team of researchers show that cells achieve this by storing extra 'skin' in folds and bumps on their surface. This cell surface excess can be rapidly deployed to cover temporary protrusions and then folded away for next time.
Published Radio signal reveals supernova origin
(via sciencedaily.com) Original source Astronomers reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf star had a helium-rich companion.
Published NASA's Spitzer, TESS find potentially volcano-covered Earth-size world
(via sciencedaily.com) Original source Astronomers have discovered an Earth-size exoplanet, or world beyond our solar system, that may be carpeted with volcanoes. Called LP 791-18 d, the planet could undergo volcanic outbursts as often as Jupiter's moon Io, the most volcanically active body in our solar system.
