Magnetic highways are contributing to gas and dust ejection in Messier 82

Magnetic highways are contributing to gas and dust ejection in Messier 82

Scientists have been searching for what's fueling the ejection of gas and dust out of Messier 82, known as the Cigar galaxy. Astronomers know the galaxy has thousands of stars coming into existence that drive a powerful super wind that blows matter into intergalactic space. The new research shows that magnetic fields are also contributing to the material being expelled from the galaxy.

Hybrid chip containing processors and memory runs AI on smart devices

Hybrid chip containing processors and memory runs AI on smart devices

A group of researchers from Stanford have developed a way to combine processors and memory on multiple hybrid chips to allow AI to run on battery-powered devices such as smartphones and tablets. The team believes that all manner of battery-power electronics would be smarter if they could run AI algorithms. The problem is efforts to build AI-capable chips for mobile devices have run up against something known as the "memory wall."

MIT researchers discover why cancer cells get energy from fermentation

MIT researchers discover why cancer cells get energy from fermentation

Scientists have known for decades that cancer cells don't metabolize sugar in the same way normal cells do. Scientists have been trying since that discovery in the 1920s to figure out why cancer cells use a method for metabolizing sugar that is much less efficient. Scientists at MIT believe they have now found a potential answer to that question.

Hubble helps astronomers pinpoint the location of a supernova

Hubble helps astronomers pinpoint the location of a supernova

Astronomers have used the Hubble Space Telescope to turn back time and determine a more accurate estimate of a supernova explosion's location and time. The star in question exploded a long time ago in the Small Magellanic Cloud, which is a satellite galaxy to the Milky Way. The exploded star left behind an expanding gaseous cloud.

Harvard robot inspired by fish swims in a school

Harvard robot inspired by fish swims in a school

Fish swimming in a massive school have complex and synchronous behaviors to help them find food, migrate, and evade predators. The school of fish isn't coordinated by a single fish or a team. Fish also don't communicate with each other about what to do next. How this swarm moves comes from something known as implicit coordination happening when an individual fish makes decisions based on what their neighbor is doing.

Scientists have identified one of the oldest planetary systems ever discovered

Researchers have identified what they say is one of the oldest planetary systems that has ever been discovered. The planetary system has a rocky planet known as TOI-561b orbiting a star that is 10 billion years old. That star is more than twice as old as the sun, and researchers say it shows planets have been forming since the early days of the universe.

Study highlights human activity in Tanzania 2 million years ago

Study highlights human activity in Tanzania 2 million years ago

A new study was recently published by principal investigators from Canada and Tanzania working with partners in Africa, North America, and Europe. The entire team is working together to describe a large assemblage of stone tools, fossil bones, and chemical proxies obtained from dental and plant materials. Researchers on the study also examined tiny microscopic bits of silica left by plants, ancient pollen, and airborne charcoal resulting from natural fires retrieved from an ancient riverbed and Lake outcrops on the Serengeti plains.

Curiosity Rover has spent 3000 Martian days on the Red Planet

NASA is celebrating a milestone for the Curiosity Rover that's been on the surface of the Red Planet since August 6, 2012. Curiosity has now spent 3000 Martian days, or sols, exploring Mars. Curiosity has been rolling up Mount Sharp, which is a three-mile-tall mountain it has been exploring since 2014.

NASA’s SLS core stage hot fire test didn’t go as planned

NASA’s SLS core stage hot fire test didn’t go as planned

Yesterday we mentioned that NASA TV would be airing the hot fire test of the SLS core stage rocket meant to push Artemis I to the moon. The core stage rocket was fueled and attached to a test sand with the intent of firing its quartet of massive rocket engines for the entire duration of time it would take for the rocket to reach orbit. However, things didn't go well, and the SLS core stage rocket ended its test 67 seconds after it began.

Astronomers discover a massive family of stars in the Milky Way

Glancing at the image below, it's clear that there are huge numbers of stars in the Milky Way. Astronomers say that the galaxy is filled with streams of stars, but one of those streams appears to have nearly 500 stars inside. Astronomers, on a new study, have discovered 8292 stellar streams in the galaxy.

NASA will air SLS core stage hot fire test

NASA will air SLS core stage hot fire test

One of the next major tests for the SLS rocket core stage will happen on January 16, which is today if you're not close to a calendar. The image above shows the core stage rocket sitting on the test stand at the NASA Stennis Space Center as it's being fueled with liquid hydrogen. The flame burning in the left of the image is liquid hydrogen being safely vented and burned as it warms and boils off during a rehearsal countdown for the hot fire test conducted on December 20.
