It has no inherent value and causes observers to rotate between feelings of fascination and anger. We’re talking about cryptocurrency, but also art. In a new series, artist Andy Bauch is bringing the two subjects together with works that use abstract patterns constructed in Lego bricks. Each piece visually represents the private key to a crypto-wallet, and anyone can steal that digital cash—if you can decode them.

Bauch first started playing around with cryptocurrencies in 2013 and told us in an interview that he considers himself an enthusiast but not a “rabid promoter” of the technology. “I wasn’t smart enough to buy enough to have fuck-you money,” he said. In 2016, he started to integrate his Bitcoin interest with his art practice.

His latest series of work, New Money, opens at LA’s Castelli Art Space on Friday. Bauch says that each piece in the series “is a secret key to various types of cryptocurrency.” He bought various amounts of Bitcoin, Litecoin, and other alt-coins in 2016 and put them in different digital wallets. Each wallet is encrypted with a private key that consists of a string of letters and numbers. That key was initially fed into an algorithm to generate a pattern. Then Bauch tweaked the algorithm here and there to get it to spit out an image that appealed to him. After finalizing the works, he’s rigorously tested them in reverse to ensure that they do, indeed, give you the right private key when processed through his formula.

Scientists have used the same technology that brought us time crystals to create a room-temperature maser—a microwave laser—that overcomes many of masers’ past problems.

Masers predate lasers. They’re pretty much the same thing, but masers shoot out microwave light instead of visible or infrared light. Lasers have always been more popular, since masers have only worked in short pulses and required incredibly cold temperatures and vacuums to operate. But now, a team of scientists in the United Kingdom has overcome both old and new challenges to debut their continuously emitting, room-temperature maser. Their research was published this week in Nature.

Masers and lasers operate on basically the same principle. Atoms typically have electrons orbiting their nuclei in specific energy levels. Add some energy in the form of, say, a photon, and the electrons jump to higher energy levels. Pump enough of those electrons into the same higher energy level, and you can release a cascade of photons of the same color (or wavelength, in physics speak) whose waves line up.

The Kepler and K2 missions have found over 2,500 planets around distant stars, but the end is coming.

Astronomers spend their time gazing out into the Universe — and occasionally the Universe seems to peer right back! This image, a composite of data from the Atacama Large Millimeter/submillimeter Array (ALMA) and the NASA/ESA Hubble Space Telescope, shows a very rare cosmic sight: a pair of interacting galaxies that have taken on an ocular structure.

As the name suggests, some types of grazing encounters between galaxies create shapes that resemble the human eye. While galaxy collisions of this type are not uncommon, only a few galaxies with eye-like, or ocular, structures have been observed. The paucity of these features is likely due to their very ephemeral nature — ocular structures like these tend to only last for several tens of millions of years, which is merely the blink of an eye in a galactic lifetime.

These two galaxies are named IC 2163 (left) and NGC 2207 (right) — IC 2163 displays the ocular structure in this image. The duo lies approximately 114 million light-years from Earth in the direction of the constellation of Canis Major (The Greater Dog).

The pair of galaxies NGC 1531/2, engaged in a spirited waltz, is located about 70 million light-years away towards the southern constellation Eridanus (The River). The deformed foreground spiral galaxy laced with dust lanes NGC 1532 is so close to its companion — the background galaxy with a bright core just above the centre of NGC 1532 — that it gets distorted: one of its spiral arms is warped and plumes of dust and gas are visible above its disc. The cosmic dance leads to another dramatic effect: a whole new generation of massive stars were born in NGC 1532 because of the interaction. They are visible as the purple objects in the spiral arms.

This exquisite image was made using the 1.5-metre Danish telescope at the ESO La Silla Observatory, Chile. It is based on data obtained through three different filters: B, V and R. The field of view is 12 × 12 arcmin.

Des Moines, IA — Tiangong-1 is expected to fall back to earth in late March or early April, and pieces could land in Iowa, Illinois, Indiana or Wisconsin.

Since their invention, computers have become faster and faster, as a result of our ability to increase the number of transistors on a processor chip.

Today, your smartphone is millions of times faster than the computers NASA used to put the first man on the moon in 1969. It even outperforms the most famous supercomputers from the 1990s. However, we are approaching the limits of this electronic technology, and now we see an interesting development: light and lasers are taking over electronics in computers.

Processors can now contain tiny lasers and light detectors, so they can send and receive data through small optical fibres, at speeds far exceeding the copper lines we use now. A few companies are even developing optical processors: chips that use laser light and optical switches, instead of currents and electronic transistors, to do calculations.

Robots, including floating spheres and spacewalkers, are performing critical tasks for astronauts and researchers as we speak.

A team of researchers with the University of Copenhagen and the Museum für Naturkunde, Leibniz-Institut für Evolutions has come up with a new explanation regarding the difference in composition of the planets in our solar system. In their paper published in the journal Nature, they describe their study of the calcium-isotope composition of certain meteorites, Earth itself, and Mars, and use what they learned to explain how the planets could be so different. Alessandro Morbidelli with Observatoire de la Côte d’Azur in France offers a News & Views piece on the work done by the team in the same journal issue.

As Morbidelli notes, most planetary scientists agree that the planets in our solar system had similar origins as small rocks orbiting the sun, comprising the protoplanetary disk, which collided and fused, creating increasingly larger rocks that eventually became protoplanets. But from that point on, it is not clear why the planets turned out so differently. In this new effort, the researchers have come up with a new theory to explain how that happened.

The protoplanets all grew at the same rate, the group suggests, but stopped growing at different times. Those that were smaller, they continue, stopped growing sooner than those that were larger. During this time, they further suggest, material was constantly being added to the disk. Early on it, it appears that the composition of the material was different from the material that came later, which explains why the rocky planets we see today have such differences in composition.
