A Norwegian startup is building massive AI robots to help airlines reduce their carbon emissions, save water, and inspect their planes in a fraction of the time it usually takes.

The challenge: The aviation industry is responsible for about 2.5% of global carbon emissions, and while sustainable jet fuels or electric propulsion systems could one day slash that figure, airlines can reduce their emissions right now — simply by cleaning their planes more often.

Washing an airplane’s exterior reduces air resistance, which means it can decrease the amount of jet fuel a plane needs to burn by up to 2% — while that’s not a huge difference, it can add up when you consider there are about 28,000 commercial jets in the global fleet.

A map of the entire human brain could help us understand where diseases come from, to how we store memories. But mapping the brain with today’s technology would take billions of dollars and hundreds of years. Learn what GR has already revealed about the brain, and how it’s making it easier for scientists to—someday—reach this goal.

Mars isn’t protected.

How can long-term space flight influence astronaut health, and specifically their organs? This is what a recent study published in Nature Communications hopes to address as a large team of international researchers conducted the most comprehensive study regarding astronaut kidney health and how it’s affected from both microgravity and galactic cosmic radiation (GCR) during long-term space missions. This study holds the potential to help astronauts, space agencies, medical professionals, and the public better understand the health risks associated with sending humans to other worlds, specifically to Mars.

“We know what has happened to astronauts on the relatively short space missions conducted so far, in terms of an increase in health issues such as kidney stones,” said Dr. Keith Siew, who is a Research Fellow in the Department of Renal Medicine at the University of College London (UCL) and lead author of the study. “What we don’t know is why these issues occur, nor what is going to happen to astronauts on longer flights such as the proposed mission to Mars.”

Aside from the 24 Apollo astronauts who traveled to the Moon, with 12 of them walking on the surface, nearly all human space travel has been limited to low-Earth orbit (LEO), totaling almost 700 people having traveled to space. During this time, they are protected by the Earth’s magnetic field, which shields them from harmful solar and cosmic radiation that could cause potentially irreparable harm to their health.

Clouds of gas in a distant galaxy are being pushed faster and faster—at more than 10,000 miles per second—out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy’s center. It’s a discovery that helps illuminate the way active black holes can continuously shape their galaxies by spurring on or snuffing out the development of new stars.

Diabetic wounds are slow-healing, potentially life-threatening complications with limited treatment options. But a two-step, nanomaterial-based strategy may open doors to better care.

Inspired by the material that makes up oyster and abalone shells, engineers at Princeton have created a new cement composite that is 17 times more crack-resistant than standard cement and 19 times more able to stretch and deform without breaking. The findings could eventually help increase the crack resistance of a wide range of brittle ceramic materials, from concrete to porcelain.

While carbon nanotubes are the materials that have received most of the attention so far, they have proved very difficult to manufacture and control, so scientists are eager to find other compounds that could be used to create nanowires and nanotubes with equally interesting properties, but easier to handle.

So, Chiara Cignarella, Davide Campi and Nicola Marzari thought to use computer simulations to parse known three-dimensional crystals, looking for those that—based on their structural and electronic properties —look like they could be easily “exfoliated,” essentially peeling away from them a stable 1-D structure. The same method has been successfully used in the past to study 2D materials, but this is the first application to their 1-D counterparts.

The researchers started from a collection of over 780,000 crystals, taken from various databases found in the literature and held together by van der Waals forces, the sort of weak interactions that happen when atoms are close enough for their electrons to overlap. Then they applied an algorithm that considered the spatial organization of their atoms looking for the ones that incorporated wire-like structures, and calculated how much energy would be necessary to separate that 1-D structure from the rest of the crystal.
