A study finds that, for now, the catalog of known black hole binaries does not reveal anything fundamental about how black holes form. More data will be needed to determine whether the invisible giants arose from a quiet galactic disk or a more dynamic cluster of stars.

A polymer-based electrolyte makes for batteries that keep working -- and don't catch fire -- when heated to over 140 degrees F.

On Dec. 11, 2021, astronomers detected a blast of high-energy light from the outskirts of a galaxy around 1 billion light-years away. The event has rattled scientists' understanding of gamma-ray bursts (GRBs), the most powerful events in the universe.

Researchers are hoping that a new, low-cost battery which holds four times the energy capacity of lithium-ion batteries and is far cheaper to produce will significantly reduce the cost of transitioning to a decarbonized economy.

Even as detailed images of distant galaxies from the James Webb Space Telescope show us more of the greater universe, scientists still disagree about how life began here on Earth. One hypothesis is that meteorites delivered amino acids -- life's building blocks -- to our planet. Now, researchers have experimentally shown that amino acids could have formed in these early meteorites from reactions driven by gamma rays produced inside the space rocks.

Peeking out from behind the glare of a bright foreground star, astronomers have uncovered the most extraordinary example yet of a nearby galaxy with characteristics that are more like galaxies in the distant, early universe. Only 1,200 light-years across, the tiny galaxy HIPASS J1131-31 has been nicknamed "Peekaboo" because of its emergence in the past 50-100 years from behind the fast-moving star that was obscuring astronomers' ability to detect it.

Scientists used high energy x-rays to investigate the solid-electrolyte interphase, a chemical layer in batteries that's key to stabilizing lithium metal anodes. Chemists unraveled this complex chemical mechanisms that is crucial for boosting energy density.

Studying an atomic clock on-board a spacecraft inside the orbit of Mercury and very near to the Sun could be the trick to uncovering the nature of dark matter.

Engineering researchers have developed a battery-free, pill-shaped ingestible biosensing system designed to provide continuous monitoring in the intestinal environment. It gives scientists the ability to monitor gut metabolites in real time, which wasn't possible before. This could unlock a new understanding of intestinal metabolite composition, which significantly impacts human health overall.

Lithium-ion batteries with high-energy-density cathodes are necessary to meet the energy demands of next-generation electronics and electric vehicles. At high voltages, however, the battery electrolyte undergoes excessive decomposition, compromising cathode performance. To tackle this, researchers have now synthesized a bio-based, non-toxic additive material that stabilizes the cathode by forming a passivation layer on its surface and suppressing its decomposition. Eco-friendly and low-cost, the novel compound could promote a wider utilization of bio-based resources.

Astronomers have determined the source of an incredibly bright X-ray, optical and radio signal appearing from halfway across the Universe.

Researchers have been able to make some key determinations about the first galaxies to exist, in one of the first astrophysical studies of the period in the early Universe when the first stars and galaxies formed, known as the cosmic dawn.

Nanoengineers have developed an AI algorithm that predicts the structure and dynamic properties of any material -- whether existing or new -- almost instantaneously. Known as M3GNet, the algorithm was used to develop matterverse.ai, a database of more than 31 million yet-to-be-synthesized materials with properties predicted by machine learning algorithms. Matterverse.ai facilitates the discovery of new technological materials with exceptional properties.

As massive as the black hole at the center of the Milky Way, the behemoth is hosted by a dwarf galaxy less than 1 million light-years away. Invisible so far -- maybe not for long.

Pioneering a new technique, researchers have peered into the extremely faint light that exists between galaxies to describe the history and state of orphan stars.
