Published Medium-sized black holes eat stars like messy toddlers
(via sciencedaily.com) Original source In new 3D computer simulations, astrophysicists modeled black holes of varying masses and then hurled stars (about the size of our sun) past them to see what might happen. If they exist, intermediate-mass black holes likely devour wayward stars like a messy toddler -- taking a few bites and then flinging the remains across the galaxy.
Published Astrophysicists reveal the nature of dark matter through the study of crinkles in spacetime
(via sciencedaily.com) Original source Astrophysicists have provided the most direct evidence yet that Dark Matter does not constitute ultramassive particles as is commonly thought but instead comprises particles so light that they travel through space like waves. Their work resolves an outstanding problem in astrophysics first raised two decades ago: why do models that adopt ultramassive Dark Matter particles fail to correctly predict the observed positions and the brightness of multiple images of the same galaxy created by gravitational lensing?
Published Scientists detect seismic waves traveling through Martian core
(via sciencedaily.com) Original source New NASA InSight research reveals that Mars has a liquid core rich in sulfur and oxygen, leading to new clues about how terrestrial planets form, evolve and potentially sustain life.
Published Pioneering research sheds new light on the origins and composition of planet Mars
(via sciencedaily.com) Original source A new study has uncovered intriguing insights into the liquid core at the centre of Mars, furthering understanding of the planet's formation and evolution.
Published New programmable smart fabric responds to temperature and electricity
(via sciencedaily.com) Original source A new smart material is activated by both heat and electricity, making it the first ever to respond to two different stimuli.
Published Making better measurements of the composition of galaxies
(via sciencedaily.com) Original source A study using data from telescopes on Earth and in the sky resolves a problem plaguing astronomers working in the infrared and could help make better observations of the composition of the universe with the James Webb Space Telescope and other instruments.
Published Even as temperatures rise, this hydrogel material keeps absorbing moisture
(via sciencedaily.com) Original source Engineers find the hydrogel polyethylene glycol (PEG) doubles its water absorption as temperatures climb from 25 to 50 C, and could be useful for passive cooling or water harvesting in warm climates.
Published Could this copycat black hole be a new type of star?
(via sciencedaily.com) Original source It looks like a black hole and bends light like a black hole, but it could actually be a new type of star. Though the mysterious object is a hypothetical mathematical construction, new simulations by Johns Hopkins researchers suggest there could be other celestial bodies in space hiding from even the best telescopes on Earth.
Published Tiny biobattery with 100-year shelf life runs on bacteria
(via sciencedaily.com) Original source A tiny biobattery that could still work after 100 years has been developed.
Published Chemists propose ultrathin material for doubling solar cell efficiency
(via sciencedaily.com) Original source Researchers are studying radical new ways to improve solar power and provide more options for the industry to explore. Chemists are proposing to make solar cells using not silicon, but an abundantly available natural material called molybdenum disulfide. Using a creative combination of photoelectrochemical and spectroscopic techniques, the researchers conducted a series of experiments showing that extremely thin films of molybdenum disulfide display unprecedented charge carrier properties that could someday drastically improve solar technologies.
Published A solar hydrogen system that co-generates heat and oxygen
(via sciencedaily.com) Original source Researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size.
Published Playing hide and seek with planets
(via sciencedaily.com) Original source An international team of astronomers announced the first exoplanet discovered through a combined approach of direct imaging and precision measurements of a star's motion on the sky. This new method promises to improve the efficiency of exoplanet searches, paving the way for the discovery of an Earth twin.
Published Microwaves advance solar-cell production and recycling
(via sciencedaily.com) Original source New technology advances solar-cell production and recycling. New microwave technology will improve the manufacture of solar cells and make them easier to recycle.
Published Processing data at the speed of light
(via sciencedaily.com) Original source Scientists have developed an extremely small and fast nano-excitonic transistor.
Published New exoplanet discovered
(via sciencedaily.com) Original source Astronomers report the first exoplanet jointly discovered through direct imaging and precision astrometry, a new indirect method that identifies a planet by measuring the position of the star it orbits. Data from the Subaru Telescope in Hawai`i and space telescopes from the European Space Agency (ESA) were integral to the team's discovery.
Published Gentle method allows for eco-friendly recycling of solar cells
(via sciencedaily.com) Original source By using a new method, precious metals can be efficiently recovered from thin-film solar cells. The method is also more environmentally friendly than previous methods of recycling and paves the way for more flexible and highly efficient solar cells.
Published A sharper look at the M87 black hole
(via sciencedaily.com) Original source The iconic image of the supermassive black hole at the center of M87 has gotten its first official makeover based on a new machine learning technique called PRIMO. The team used the data achieved the full resolution of the array.
Published M87 in 3D: New view of galaxy helps pin down mass of the black hole at its core
(via sciencedaily.com) Original source From Earth, giant elliptical galaxies resemble highly symmetric blobs, but what's their real 3D structure? Astronomers have assembled one of the first 3D views of a giant elliptical galaxy, M87, whose central supermassive black hole has already been imaged by the Event Horizon Telescope. M87 turns out to be triaxial, like a potato. The revised view provides a more precise measure of the mass of the central black hole: 5.37 billion solar masses.
Published James Webb Space Telescope images challenge theories of how universe evolved
(via sciencedaily.com) Original source Astronomers find that six of the earliest and most massive galaxy candidates observed by the James Webb Space Telescope so far appear to have converted nearly 100% of their available gas into stars, a finding at odds with the reigning model of cosmology.
Published Chemists redesign biological PHAs, 'dream' biodegradable plastics
(via sciencedaily.com) Original source They've been called 'dream' plastics: polyhydroxyalkanoates, or PHAs. Already the basis of a fledgling industry, they're a class of polymers naturally created by living microorganisms, or synthetically produced from biorenewable feedstocks. They're biodegradable in the ambient environment, including oceans and soil.
