From the perspective of future societies, in extremely closed environments such as a space station, self-sufficiency in food cultivation and waste management is critical. However, the technology to achieve this is still lacking. In a new study, scientists shed light on their most recent breakthrough: a cheap and efficient method to make liquid fertilizer (ammonia) from simplified artificial urine, serving an ideal dual purpose of growing food and treating waste.

Thinking like Earthlings may have caused scientists to overlook the electrochemical effects of Martian dust storms. On Earth, dust particles are viewed mainly in terms of their physical effects, like erosion. But, in exotic locales from Mars to Venus to Jupiter’s icy moon Europa, electrical effects can affect the chemical composition of a planetary body’s surface and atmosphere in a relatively short time, according to new research.

A team of astronomers used the Keck I telescope to measure the distance to an ancient galaxy. They deduced the target galaxy GN-z11 is not only the oldest galaxy but also the most distant. It’s so distant it defines the very boundary of the observable universe itself. The team hopes this study can shed light on a period of cosmological history when the universe was only a few hundred million years old.

Is it possible to read a person’s mind by analyzing the electric signals from the brain? The answer may be much more complex than most people think. Researchers working at the intersection of artificial intelligence and neuroscience say a prominent dataset used to try to answer this question is confounded, and therefore many eye-popping findings that were based on this dataset and received high-profile recognition are false after all.

Researchers have used the ancient Japanese art of paper folding to possibly solve a key challenge for outer space travel – how to store and move fuel to rocket engines. They have developed an origami-inspired, folded plastic fuel bladder that doesn’t crack at super cold temperatures and could someday be used to store and pump fuel.

The researchers report that they have built an atomic clock that measures not a cloud of randomly oscillating atoms, as state-of-the-art designs measure now, but instead atoms that have been quantumly entangled. The atoms are correlated in a way that is impossible according to the laws of classical physics, and that allows the scientists to measure the atoms’ vibrations more accurately.

By monitoring the cosmos with a radio telescope array, an international team of scientists has detected radio bursts emanating from the constellation Boötes – that could be the first radio emission collected from a planet beyond our solar system.

One of Canada’s astronauts will be sent around the Moon as part of a partnership between NASA and the Canadian Space Agency (CSA), NASA announced on Wednesday. The two organizations have formally agreed to collaborate on building a lunar space station called the Lunar Gateway. The Gateway is just one part of NASA’s larger Artemis program, which is focused on landing a woman on the Moon by 2024.

Using data from NASA’s Cassini spacecraft, scientists modeled chemical processes in the subsurface ocean of Saturn’s moon Enceladus. The studies indicate the possibility that a varied metabolic menu could support a potentially diverse microbial community in the liquid water ocean beneath the moon’s icy facade.

A team has now for the first time observed a gas filament with a length of 50 million light years. Its structure is strikingly similar to the predictions of computer simulations. The observation therefore also confirms our ideas about the origin and evolution of our universe.

For the first time, hard-to-track lithium has been identified and measured in the atmosphere of burned out stars called white dwarfs, according to a study. Lithium helps power cell phones and computers and stabilize moods. But scientists have been stumped by what’s become of the lithium that was expected from the Big Bang, a discrepancy known as the “cosmological lithium problem.”

Super-fast quantum computers and communication devices could revolutionize countless aspects of our lives — but first, researchers need a fast, efficient source of the entangled pairs of photons such systems use to transmit and manipulate information. Researchers have now done just that, creating a chip-based photon source 100 times more efficient than previously possible. The work brings massive quantum device integration within reach.
