While designing anything for operation in space has its challenges, there is at least one thing that is more of a problem for objects in Earth orbit than for deep-space probes: atomic oxygen. We li…
Severed fragments of a sea cucumber kept living and thriving instead of decaying, puzzling researchers.
Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a new paper published in Proceedings of the Royal Society A, mathematicians from the University of California, Davis, provide mathematic…
On 18 March 1965, at 07:00 GMT, the Soviet spacecraft Voskhod 2 lifted off from Baikonur Cosmodrome carrying two cosmonauts: Pavel Belyayev, the mission commander, and Alexei Leonov, then thirty years old, the man assigned to make the first spacewalk in human…
There’s a newly crowned T. rex. This one, called Tylosaurus rex, was a tyrant of the sea and mosasaur spanning up to 43 feet in length.
A rare blue micromoon will appear in night skies this weekend. Here's what to expect.
Quantum mechanics is a physics framework that describes how matter and energy behave at an extremely small scale, specifically at the scale of atoms and subatomic particles. An effect predicted by the laws of quantum mechanics is superposition, which entails …
Of all the objects in the Universe, few are as perplexing as black holes.
Embedded in the Sounds of Earth section of the Voyager Golden Record is something that does not appear on any track listing: an hour-long recording of the heartbeat and brainwaves of Ann Druyan, compressed into the span of a minute to fit onto the record. It …
Two pairs of ‘rogue’ Jupiter-size, planet-like objects have been found in a large star-forming region in the Milky Way, a new study claims. The findings suggest the weird objects actually do exist, and are not an illusion.
Wild disturbances are on the rise, while land disturbed by human activity has been decreasing.
"It's sort of a side branch."
Extraterrestrial dust falls on every part of the Earth, including the parts covered in cities. Most of it arrives as grains a few hundredths to a few tenths of a millimetre across, finer than a grain of sand or close to it, and it lands without anyone noticin…
Researchers have discovered a new type of giant virus, which replicates in a way we've never seen before.
Although resistors are hardly among the most exciting components, they are arguably one of the most important ones, as anyone who has done any amount of circuit design and debugging can attest to. …
In December 2019, astronomers detected a one hour brightening of a star in the Large Magellanic Cloud, a classic gravitational microlensing event. These occur when a compact object bends a distant the light of a distant star as it passes in front of it. The o…
The metabolite αKG promotes carnitine synthesis and increases site-specific histone acetylation, thereby promoting homologous recombination-mediated DNA repair, which has potential implications for chemoresistant cancers.
A spatiotemporal transcriptome atlas of whole-human embryos after gastrulation and previously transcriptionally undescribed stages of human development are reported.
Inside the longevity conference that brings together founders, investors, biohackers, and the generally death-averse to discuss how to forestall — or even beat — our demise.
NSUN2 is an enzyme that adds a small chemical mark to RNA molecules and uniquely selects its targets based on specific sequence patterns and structural features.
