Published New insights into neutrino interactions
(via sciencedaily.com)
Original source 
Elusive fundamental particles called neutrinos are predicted to interact unexpectedly with photons under extreme conditions.
Published Bacteria generate electricity from wastewater
(via sciencedaily.com) 
In a breakthrough for the field of bioelectronics, researchers have enhanced the ability of E. coli bacteria to generate electricity. The innovative approach only offers a sustainable solution for organic waste processing while outperforming previous state-of-the-art technologies, opening new horizons for versatile microbial electricity production.
Published Study hints at the existence of the closest black holes to Earth in the Hyades star cluster
(via sciencedaily.com) 
A new article hints at the existence of several black holes in the Hyades cluster -- the closest open cluster to our solar system -- which would make them the closest black holes to Earth ever detected.
Published New study highlights feasibility and optimization of ammonia-based power generation for carbon neutrality
(via sciencedaily.com) 
A research team has evaluated the feasibility of ammonia-based power generation through techno-economic and carbon footprint analyses.
Published New study reveals the power of railroads to buffer coal plants from a carbon emissions tax
(via sciencedaily.com) 
A new study suggests that railroads are likely to cut transportation prices to prop up coal-fired plants if U.S. climate policies further disadvantage coal in favor of less carbon-intensive energy sources.
Published Ravenous black hole consumes three Earths'-worth of star every time it passes
(via sciencedaily.com) 
Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly disrupted by a low mass black hole has been seen, opening the possibility of a range of star and black hole combinations to be discovered.
Published New cosmological constraints on the nature of dark matter
(via sciencedaily.com) 
New research has revealed the distribution of dark matter in never before seen detail, down to a scale of 30,000 light-years. The observed distribution fluctuations provide better constraints on the nature of dark matter.
Published Scientists develop new method to recover high-purity silicon from expired solar panels for upcycling into lithium-ion batteries
(via sciencedaily.com) 
Scientists have devised an efficient method of recovering high-purity silicon from expired solar panels to produce lithium-ion batteries that could help meet the increasing global demand to power electric vehicles.
Published Devices offers long-distance, low-power underwater communication
(via sciencedaily.com) 
A new underwater communication and networking technique can achieve kilometer-scale ranges while consuming about one-millionth the power required by current communication methods.
Published New material offers more durable, sustainable multi-level non-volatile phase change memory
(via sciencedaily.com) 
Researchers scientists have unlocked a new realm of possibilities for non-volatile phase change memory, a type of electronic memory capable of retaining data even without power. Traditionally, researchers have relied on chalcogenides, materials with reversible electrical properties during transitions between crystalline and amorphous states. But an exciting alternative has emerged in the form of layered nickelates, complex oxide materials composed of nickel ions. These nickelates, with their unique layered structure and thermally reversible switching of room-temperature electrical resistivity, offer superior performance and sustainability potential.
Published Furthest ever detection of a galaxy's magnetic field
(via sciencedaily.com) 
Astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides astronomers with vital clues about how the magnetic fields of galaxies like our own Milky Way came to be.
Published Vast bubble of galaxies discovered, given Hawaiian name
(via sciencedaily.com)
Original source 
The immense bubble is 820 million light years from Earth and believed to be a fossil-like remnant of the birth of the universe.
Published Electrifying heavy-duty vehicles could reduce environmental inequalities
(via sciencedaily.com) 
If the region surrounding Chicago -- North America's largest freight hub -- shifted just 30% of its current on-road heavy-duty vehicles to electric versions, it would substantially reduce pollution and save hundreds of lives per year, with the benefits largely concentrated in disadvantaged communities, according to a new study. The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.
Published Scientists develop an energy-efficient wireless power and information transfer system
(via sciencedaily.com) 
Simultaneous wireless information and power transfer (SWIPT)-aided nonorthogonal multiple access (NOMA) system, used for communication in the Industrial Internet of Things (IIoTs), suffers from significant energy loss with transmission distance. Now, researchers have developed an energy-efficient framework by applying SWIPT-NOMA to a distributed antenna system. This technology is expected to pave the way for more efficient and optimized IoT environments.
Published Better cybersecurity with new material
(via sciencedaily.com) 
Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.
Published Hot Jupiter blows its top
(via sciencedaily.com) 
The planet HAT-P-32b is losing so much of its atmospheric helium that the trailing gas tails are among the largest structures yet known any planet outside our solar system. Three-dimensional (3D) simulations helped model the flow of the planet's atmosphere. The scientists hope to widen their planet-observing net and survey 20 additional star systems to find more planets losing their atmosphere and learn about their evolution.
Published Webb reveals new structures within iconic supernova
(via sciencedaily.com) 
NASA's James Webb Space Telescope has begun the study of one of the most renowned supernovae, SN 1987A (Supernova 1987A). Located 168,000 light-years away in the Large Magellanic Cloud, SN 1987A has been a target of intense observations at wavelengths ranging from gamma rays to radio for nearly 40 years, since its discovery in February of 1987. New observations by Webb's NIRCam (Near-Infrared Camera) provide a crucial clue to our understanding of how a supernova develops over time to shape its remnant.
Published Scientists detect and validate the longest-period exoplanet found with TESS
(via sciencedaily.com) 
Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.
Published New giant planet evidence of possible planetary collisions
(via sciencedaily.com) 
A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash.
Published Unprecedented gamma-ray burst explained by long-lived jet
(via sciencedaily.com) 
While astrophysicists previously believed that only supernovae could generate long gamma-ray bursts (GRBs), a 2021 observation uncovered evidence that compact-object mergers also can generate the phenomenon. Now, a new simulation confirms and explains this finding. If the accretion disk around the black hole is massive, it launches a jet that lasts several seconds, matching the description of a long GRB from a merger.
