While multi-material 3D printers do already exist, the filament they extrude is all one material at any one point in the printing process. A new system produces actual multi-material filaments, however, and they boast a very useful helical design.

Harvard scientists have investigated why we age, and how we could stop it. In tests in mice, the team showed that epigenetic “software glitches” drive the symptoms of aging – and a system reboot can reverse them, potentially extending lifespan.

By using a labeling system, a research team found that it was possible to shift dining choices away from climate-straining red meat consumption and towards more eco-friendly plant-based options.

One ant is not very smart, but together they can achieve some remarkable things. Inspired by this emergent cooperative behavior, Harvard researchers have built robots that can work together to escape from a “prison,” without needing a specific plan.

A study looking at post-mortem brain tissue samples has found severe COVID-19 is associated with molecular signs of brain aging. The researchers warn potential long-term neurological problems could emerge in the years following the pandemic.

Wormholes are a sci-fi staple, and and it's possible that they exist in the real universe. But how would they work? Physicists have now used a quantum processor to simulate a traversable wormhole, teleporting information between two quantum systems.

When a limb is rendered immobile for long periods of time, its muscles will inevitably begin to atrophy. A new implant could help keep that from happening, however, by mechanically stretching and compressing those muscles.

Folks with a soft touch seem to have no problem getting to grips with delicate objects, but it can be a tough ask for robots. Researchers have taken a strength-in-numbers approach with a gripper that curls multiple tubes around a fragile object.

Two new studies in the journal Cell have reported on unexpected ways pain-sensing neurons in the gut can serve as more than just sensory alarm systems. The research suggests these neurons also can directly protect the gut from inflammatory damage.

Black holes chow down on stars that wander too close, producing a bright stellar show. But now a black hole has done something nobody’s ever seen before – it “burped up” material several years after eating a star, leaving astronomers baffled.

A new study from scientists at MIT and Harvard University has delved into the complex relationship between nutrition, exercise and the human body, and turned up some fascinating insights around the way they impact on cells.

Gases used as refrigerants in cooling systems can leak into the atmosphere and become major contributors to climate change. Now engineers at Harvard have demonstrated a new prototype cooling device that uses a solid-state material as a refrigerant.
