Published Detection of bacteria and viruses with fluorescent nanotubes
(via sciencedaily.com) The new carbon nanotube sensor design resembles a molecular toolbox that can be used to quickly assemble sensors for a variety of purposes -- for instance for detecting bacteria and viruses.
Published Galaxy J1135 reveals its water map
(via sciencedaily.com) Researchers look at water in galaxies, its distribution and in particular its changes of state from ice to vapor, as important markers indicating areas of increased energy, in which black holes and stars are formed. A new study has now revealed the distribution of water within the J1135 galaxy, which is 12 billion light years away and formed when the Universe was a 'teenager', 1.8 billion years after the Big Bang . This water map, with unprecedented resolution, is the first ever to be obtained for such a remote galaxy. The map can help scientists to understand the physical processes taking place within J1135 and shed light on the dynamics, still partially unclear, surrounding the formation of stars, black holes and galaxies themselves.
Published Researchers put a new twist on graphite
(via sciencedaily.com) Original source Researchers report that it is possible to imbue graphite -- the bulk, 3D material found in No. 2 pencils -- with physical properties similar to graphite's 2D counterpart, graphene. Not only was this breakthrough unexpected, the team also believes its approach could be used to test whether similar types of bulk materials can also take on 2D-like properties. If so, 2D sheets won't be the only source for scientists to fuel technological revolutions. Bulk, 3D materials could be just as useful.
Published Does this exoplanet have a sibling sharing the same orbit?
(via sciencedaily.com) Astronomers have found the possible 'sibling' of a planet orbiting a distant star. The team has detected a cloud of debris that might be sharing this planet's orbit and which, they believe, could be the building blocks of a new planet or the remnants of one already formed. If confirmed, this discovery would be the strongest evidence yet that two exoplanets can share one orbit.
Published The puzzle of the galaxy with no dark matter
(via sciencedaily.com) New research has found the first evidence of a massive galaxy with no dark matter. The result is a challenge to the current standard model of cosmology.
Published Unusual white dwarf star is made of hydrogen on one side and helium on the other
(via sciencedaily.com) Original source In a first for white dwarfs, the burnt-out cores of dead stars, astronomers have discovered that at least one member of this cosmic family is two faced. One side of the white dwarf is composed of hydrogen, while the other is made up of helium.
Published VERA unveils surroundings of rapidly growing black holes
(via sciencedaily.com) Astronomers used the state-of-the-art capability of VERA, a Japanese network of radio telescopes, to uncover valuable clues about how rapidly growing 'young' supermassive black holes form, grow, and possibly evolve into more powerful quasars.
Published Researchers achieve historic milestone in energy capacity of supercapacitors
(via sciencedaily.com) Original source In a new landmark chemistry study, researchers describe how they have achieved the highest level of energy storage -- also known as capacitance -- in a supercapacitor ever recorded.
Published Astronomers discover striking evidence of 'unusual' stellar evolution
(via sciencedaily.com) Astronomers have found evidence that some stars boast unexpectedly strong surface magnetic fields, a discovery that challenges current models of how they evolve.
Published Engineers' storage technology keeps nanosurfaces clean
(via sciencedaily.com) Engineers have created containers that can keep volatile organic compounds from accumulating on the surfaces of stored nanomaterials. Their portable and inexpensive technology improves on a 50-year-old idea to address a ubiquitous problem in nanomanufacturing and materials science.
Published Hubble views a galactic monster
(via sciencedaily.com) The NASA/ESA Hubble Space Telescope has captured a monster in the making in this observation of the exceptional galaxy cluster eMACS J1353.7+4329, which lies about eight billion light-years from Earth in the constellation Canes Venatici. This collection of at least two galaxy clusters is in the process of merging together to create a cosmic monster, a single gargantuan cluster acting as a gravitational lens.
Published Stellar cradles and graves seen in farthest galaxy ever
(via sciencedaily.com) Original source New observations have distinguished the sites of star formation and a possible site of star death from the surrounding nebula in a galaxy 13.2 billion light-years away. This is the farthest that such structures have been observed.
Published Astronomers identify the coldest star yet that emits radio waves
(via sciencedaily.com) Original source Brown dwarf stars rarely emit radio waves. Here scientists have found the coldest star yet emitting at these long wave lengths. Understanding the science of 'ultracool brown dwarfs' will help deepen our knowledge of how stars evolve.
Published James Webb Telescope catches glimpse of possible first-ever 'dark stars'
(via sciencedaily.com) Three bright objects initially identified as galaxies in observations from the James Webb Space Telescope might actually represent an exotic new form of star. If confirmed, the discovery would also shed light on the nature of dark matter.
Published Rare, double-lobe nebula resembles overflowing cosmic 'jug'
(via sciencedaily.com) Original source A billowing pair of nearly symmetrical loops of dust and gas mark the death throes of an ancient red-giant star. The resulting structure, said to resemble an old style of English jug, is a rarely seen bipolar reflection nebula. Evidence suggests that this object formed by the interactions between the dying red giant and a now-shredded companion star.
Published When the stars align: Astronomers find answers to mysterious action of ghost stars in our Galaxy
(via sciencedaily.com) Original source Scientists have found a source for the mysterious alignment of stars near the Galactic Center.
Published Analogous to algae: Scientists move toward engineering living matter by manipulating movement of microparticles
(via sciencedaily.com) A team of scientists has devised a system that replicates the movement of naturally occurring phenomena, such as hurricanes and algae, using laser beams and the spinning of microscopic rotors.
Published New material could hold key to reducing energy consumption in computers and electronics
(via sciencedaily.com) A University of Minnesota Twin Cities team has, for the first time, synthesized a thin film of a unique topological semimetal material that has the potential to generate more computing power and memory storage while using significantly less energy.
Published Search for dark matter
(via sciencedaily.com) Original source Scientists have applied a promising new method to search for dark matter particles in a particle accelerator. The method is based on the observation of the spin polarization of a particle beam in a storage ring COSY.
Published Webb celebrates first year of science with close-up on birth of sun-like stars
(via sciencedaily.com) Original source From our cosmic backyard in the solar system to distant galaxies near the dawn of time, NASA's James Webb Space Telescope has delivered on its promise of revealing the universe like never before in its first year of science operations. To celebrate the completion of a successful first year, NASA has released Webb's image of a small star-forming region in the Rho Ophiuchi cloud complex.
