Published Research captures and separates important toxic air pollutant
(via sciencedaily.com) A series of new stable, porous materials that capture and separate benzene have been developed.
Published Discovery of massive early galaxies defies prior understanding of the universe
(via sciencedaily.com) Six massive galaxies discovered in the early universe are upending what scientists previously understood about the origins of galaxies in the universe.
Published Electrodes grown in the brain -- paving the way for future therapies for neurological disorders
(via sciencedaily.com) The boundaries between biology and technology are becoming blurred. Researchers have now successfully grown electrodes in living tissue using the body's molecules as triggers. The result paves the way for the formation of fully integrated electronic circuits in living organisms.
Published Plastic upcycling to close the carbon cycle
(via sciencedaily.com) Original source A new method to convert waste plastic to fuel and raw materials promises to help close the carbon cycle at mild temperature and with high yield.
Published Novel air filter captures wide variety of pollutants
(via sciencedaily.com) Original source An air filter made out of corn protein instead of petroleum products can concurrently capture small particulates as well as toxic chemicals like formaldehyde that current air filters can't. The research could lead to better air purifiers, particularly in regions of the world that suffer from very poor air quality. The more environmentally friendly air filter was able to simultaneously capture 99.5% of small particulate matter, similar to commercial HEPA filters, and 87% of formaldehyde, which is higher than specially designed air filters for those types of toxics.
Published James Webb spots super old, massive galaxies that shouldn't exist
(via sciencedaily.com) A team of international researchers have identified six candidate galaxies that existed roughly 500 to 700 million years after the Big Bang and are about as big as the modern Milky Way Galaxy -- a feat that scientists didn't think was possible.
Published HETDEX reveals galaxy gold mine in first large survey
(via sciencedaily.com) The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) announced their first publicly released catalog of astronomical objects. Over 200,000 astronomical objects including distant stars and galaxies have been mapped in 3D for the first time. Astronomers will use the data to better determine the Hubble constant, used to gauge the expansion of the universe. Possible 'naked black hole' early highlight of science results from HETDEX survey. TACC systems Corral, Stampede2, and Maverick were used in the data analysis and storage. Data publicly available through JupyterHub notebooks.
Published Footprints of galactic immigration uncovered in Andromeda galaxy
(via sciencedaily.com) Astronomers have uncovered striking new evidence for a mass migration of stars into the Andromeda Galaxy. Intricate patterns in the motions of stars reveal an immigration history very similar to that of the Milky Way.
Published Star formation in distant galaxies by the James Webb Space Telescope
(via sciencedaily.com) Thanks to the James Webb Space Telescope's first images of galaxy clusters, researchers have, for the very first time, been able to examine very compact structures of star clusters inside galaxies, so-called clumps.
Published 'Engine' of luminous merging galaxies pinpointed for the first time
(via sciencedaily.com) Roughly 500 million light-years away, near the constellation Delphinus, two galaxies are colliding. Known as merging galaxy IIZw096, the luminous phenomenon is obscured by cosmic dust, but researchers first identified a bright, energetic source of light 12 years ago. Now, with a more advanced telescope, the team has pinpointed the precise location of what they have dubbed the 'engine' of the merging galaxy.
Published Astronomers uncover a one-in-ten-billion binary star system: Kilonova progenitor system
(via sciencedaily.com) Astronomers using data from the SMARTS 1.5-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO), have made the first confirmed detection of a star system that will one day form a kilonova -- the ultra-powerful, gold-producing explosion created by merging neutron stars. These systems are so phenomenally rare that only about 10 such systems are thought to exist in the entire Milky Way.
Published The bubbling universe: A previously unknown phase transition in the early universe
(via sciencedaily.com) What happened shortly after the universe was born in the Big Bang and began to expand? Bubbles occurred and a previously unknown phase transition happened, according to particle physicists.
Published Scientists release newly accurate map of all the matter in the universe
(via sciencedaily.com) A group of scientists have released one of the most precise measurements ever made of how matter is distributed across the universe today.
Published Were galaxies much different in the early universe?
(via sciencedaily.com) The most sensitive telescope now searching for radio signals from cosmic dawn, an era around 200 million years after the Big Bang when stars ignited, has doubled its sensitivity, a new paper reports. While not yet detecting this radiation -- the redshifted 21-centimeter line -- they have put new limits on the elemental composition of galaxies during the Epoch of Reionization. Early galaxies seem to be low in metals, fitting the most popular theory of cosmic evolution.
Published Darkest view ever of interstellar ice
(via sciencedaily.com) Original source Astronomers used observations from the James Webb Space Telescope (JWST) to achieve the darkest ever view of a dense interstellar cloud. These observations have revealed the composition of a virtual treasure chest of ices from the early universe, providing new insights into the chemical processes of one of the coldest, darkest places in the universe as well as the origins of the molecules that make up planetary atmospheres.
Published The mechanism of cosmic magnetic fields explored in the laboratory
(via sciencedaily.com) Recent research shows that magnetic fields can spontaneously emerge in a plasma if the plasma has a temperature anisotropy. This mechanism is known as the Weibel instability. This new research is the first to unambiguously observe the Weibel instability in the laboratory. It offers a possible solution to the problem of the origin of the microgauss-level magnetic fields that permeate the galaxies.
Published Researchers measure size-luminosity relation of galaxies less than a billion years after Big Bang
(via sciencedaily.com) A team has studied the relation between galaxy size and luminosity of some of the earliest galaxies in the universe taken by the James Webb Space Telescope, less than a billion years after the Big Bang.
Published NASA's Webb uncovers star formation in cluster's dusty ribbons
(via sciencedaily.com) NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, it is less mysterious with new findings from NASA's James Webb Space Telescope.
Published Ultracool dwarf binary stars break records
(via sciencedaily.com) Astrophysicists have discovered the tightest ultracool dwarf binary system ever observed. The two stars are so close that it takes them less than one Earth day to revolve around each other. In other words, each star's 'year' lasts just 20.5 hours.
Published Wide diversity of galaxies in the early universe
(via sciencedaily.com) New data have revealed that the structures of galaxies in the early universe were much more diverse and mature than previously known. JWST's ability to see faint high redshift galaxies in sharper detail than Hubble allowed the team of researchers to resolve more features and see a wide mix of galaxies.
