ANIMATION Using a combination of telescopes, including the Very Large Telescope of the European Southern Observatory (ESO’s VLT), astronomers have revealed a system consisting of six exoplanets, five of which are locked in a rare rhythm around their central star. The researchers believe the system could provide important clues about how planets, […]

Researchers at Tokyo Medical and Dental University (TMDU) in Japan show that melatonin and its metabolites promote the formation of long-term memories in mice and protect against cognitive decline. Researchers at Tokyo Medical and Dental University (TMDU) showed that melatonin’s metabolite AMK can enhance the formation of long-term memories in […]

Planetary nebula ESO 455-10 captured by the Hubble Space Telescope. Credit: ESA/Hubble & NASA, L. Stanghellini The lives of planetary nebulae are often chaotic, from the death of their parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such […]

MIT researchers have developed an automated way to design customized hardware, or “brains,” that speeds up a robot’s operation. A new system devises hardware architectures to hasten robots’ response time. Contemporary robots can move quickly. “The motors are fast, and they’re powerful,” says Sabrina Neuman. Yet in complex situations, like interactions with […]

ANIMATION New anode for aqueous batteries allows use of cheap, plentiful seawater as an electrolyte. Lithium-ion batteries are critical for modern life, from powering our laptops and cell phones to those new holiday toys. But there is a safety risk – the batteries can catch fire. Zinc-based aqueous batteries avoid […]

Nanosatellite thrusters that emit a stream of pure ions are the first of their kind to be entirely additively manufactured, using a combination of 3D printing and hydrothermal growth of zinc oxide nanowires. A stainless steel version (top) works better overall but is much more expensive to produce. MIT researchers […]
