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 Smart stitches could reduce infection and simplify post op monitoring
(via sciencedaily.com) A new antimicrobial suture material that glows in medical imaging could provide a promising alternative for mesh implants and internal stitches.
Published Thin, lightweight layer provides radiation barrier for perovskites in space, protection from elements on Earth
(via sciencedaily.com) An ultrathin protective coating proves sufficient to protect a perovskite solar cell from the harmful effects of space and harden it against environmental factors on Earth, according to newly published research.
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 Transforming the way cancer vaccines are designed and made
(via sciencedaily.com) A new way to significantly increase the potency of almost any vaccine has been developed. The scientists used chemistry and nanotechnology to change the structural location of adjuvants and antigens on and within a nanoscale vaccine, greatly increasing vaccine performance in seven different types of cancer. The architecture is critical to vaccine effectiveness, the study shows.
Published This groundbreaking biomaterial heals tissues from the inside out
(via sciencedaily.com) A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.
Published Volcano-like rupture could have caused magnetar slowdown
(via sciencedaily.com) In October 2020, a highly magnetic neutron star called SGR 1935+2154 abruptly began spinning more slowly. Astrophysicist now show the magnetar's rotational slowdown could have been caused by a volcano-like rupture near its magnetic pole.
Published Starry tail tells the tale of dwarf galaxy evolution
(via sciencedaily.com) A giant diffuse tail of stars has been discovered emanating from a large, faint dwarf galaxy. The presence of a tail indicates that the galaxy has experienced recent interaction with another galaxy. This is an important clue for understanding how so called 'ultra-diffuse' galaxies are formed.
Published Solar System formed from 'poorly mixed cake batter,' isotope research shows
(via sciencedaily.com) Earth's potassium arrived by meteoritic delivery service finds new research led by Earth and planetary scientists. Their work shows that some primitive meteorites contain a different mix of potassium isotopes than those found in other, more-chemically processed meteorites. These results can help elucidate the processes that shaped our Solar System and determined the composition of its planets.
Published Researchers demo new type of carbon nanotube yarn that harvests mechanical energy
(via sciencedaily.com) Nanotechnology researchers have made novel carbon nanotube yarns that convert mechanical movement into electricity more effectively than other material-based energy harvesters.
Published NASA's Fermi detects first gamma-ray eclipses from 'spider' star systems
(via sciencedaily.com) Scientists have discovered the first gamma-ray eclipses from a special type of binary star system using data from NASA's Fermi Gamma-ray Space Telescope. These so-called spider systems each contain a pulsar -- the superdense, rapidly rotating remains of a star that exploded in a supernova -- that slowly erodes its companion.
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 Spin transport measured through molecular films now long enough to develop spintronic devices
(via sciencedaily.com) Original source A research group has succeeded in measuring spin transport in a thin film of specific molecules -- a material well-known in organic light emitting diodes -- at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been used to control spin transport in the past, the thin molecular film used in this study is photoconductive, allowing spin transport control using visible light.
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 Incorporation of water molecules into layered materials impacts ion storage capability
(via sciencedaily.com) Researchers have experimentally detected the structural change of hydration water confined in the tiny nano-scale pores of layered materials such as clays. Their findings potentially open the door to new options for ion separation and energy storage.
Published New nanoparticles deliver therapy brain-wide, edit Alzheimer's gene in mice
(via sciencedaily.com) Researchers describe a new family of nano-scale capsules made of silica that can carry genome-editing tools into many organs around the body and then harmlessly dissolve.
Published Massive fuel-hungry black holes feed off intergalactic gas
(via sciencedaily.com) Research has revealed how supermassive black holes (SMBHs) are feeding off gas clouds which reach them by traveling hundreds of thousands of light years from one galaxy to another.
Published Nanoparticles make it easier to turn light into solvated electrons
(via sciencedaily.com) Solutions containing solvated electrons are inherently clean chemical reactants, and they could become easier and cheaper to make now that chemists have uncovered the long-sought mechanism of a light-driven process that creates them.
Published Billions of celestial objects revealed in gargantuan survey of the Milky Way
(via sciencedaily.com) Original source Astronomers have released a gargantuan survey of the galactic plane of the Milky Way. The new dataset contains a staggering 3.32 billion celestial objects -- arguably the largest such catalog so far. The data for this unprecedented survey were taken with the Dark Energy Camera.
