A 3,400-foot-wide asteroid will make a safe flyby of Earth next week

“A huge asteroid will safely whiz by our planet next week. The asteroid, known as 7482 (1994 PC1), will make its closest approach to our planet on Jan. 18 at 4:51 p.m. EST (2151 GMT), according to a …

Algorithm helps robots avoid obstacles in their path

“If you’ve ever ordered a product from Amazon, chances are that a robot selected your purchase from a shelf, read the barcode and delivered it to the counter for packaging. Hopefully, it didn’t collide with a human worker …

An optical chip improved by light

“At EPFL, a team of scientists created and observed a new physical phenomenon on an optical chip using modified lights. Technology is increasingly moving towards miniaturization and energy efficiency. This also applies to electronic chips. Light, and optics more broadly …

Assessing Perseverance’s Seventh Sample Collection

“On Wednesday, Dec. 29 (sol 306) Perseverance successfully cored and extracted a sample from a Mars rock. Data downlinked after the sampling indicates that coring of the rock the science team nicknamed Issole went smoothly. However, during the transfer of …

Atom by atom: new silicon computer chip technique opens up quantum computing construction possibilities

“Quantum computers could be constructed cheaply and reliably using a new technique perfected by a University of Melbourne-led team that embeds single atoms in silicon wafers, one-by-one, mirroring methods used to build conventional devices, in a process outlined in an …

Computer Model Seeks to Explain the Spread of Misinformation, and Suggest Counter Measures

“It starts with a superspreader, and winds its way through a network of interactions, eventually leaving no one untouched. Those who have been exposed previously may experience little effect when exposed to a different variant. No, it’s not a …

Dark Energy Spectroscopic Instrument (DESI) Creates Largest 3D Map of the Cosmos

“The Dark Energy Spectroscopic Instrument (DESI) has capped off the first seven months of its survey run by smashing through all previous records for three-dimensional galaxy surveys, creating the largest and most detailed map of the universe ever. Yet it …

Euler’s 243-Year-Old ‘Impossible’ Puzzle Gets a Quantum Solution

“In 1779, the Swiss mathematician Leonhard Euler posed a puzzle that has since become famous: Six army regiments each have six officers of six different ranks. Can the 36 officers be arranged in a 6-by-6 square so that no row …

Graphene could replace rare metal used in mobile phone screens

“A new study, published in the journal Advanced Optical Materials, is the first to show graphene can replace Indium Tin Oxide (ITO) in an electronic or optical device. Researchers from Paragraf and Queen Mary University of London demonstrated the successful …

Light-Matter Interactions Simulated on the World’s Fastest Supercomputer

“Light-matter interactions form the basis of many important technologies, including lasers, light-emitting diodes (LEDs), and atomic clocks. However, usual computational approaches for modeling such interactions have limited usefulness and capability. Now, researchers from Japan have developed a technique that overcomes …
