Researchers have incorporated living microbes into 3D printed objects. The resin material is embedded with chemical “instructions” that tell a layer of microbes to fluoresce in particular colors, producing a stunning array of patterns and designs.

A team of Harvard scientists has finally solved the mystery of how acute stress causes hair to turn gray. The researchers discovered when stress triggers the "fight or flight" response, it depletes pigment-producing stem cells in hair follicles.

It sure sounds like an online pop-up ad, but Harvard scientists have created and tested a new treatment that melts away body fat. The new technique involves injecting an icy saline solution directly into fat deposits to shrink them by half.

Parents of children with autism have often reported a strange phenomenon: when their child has a fever, their behavioral symptoms seem to improve. Now a new study from MIT and Harvard may have uncovered why.

New research from Harvard suggests some single-celled organisms may be capable of more complex decision-making than we give them credit for. In experiments, they were found to consult a hierarchy of options and be capable of “changing their minds.”

At the atomic scale, things happen much faster than we can see. Now Harvard researchers have slowed things down by cooling molecules to almost absolute zero – the coldest chemical reaction ever recorded, capturing never-before seen molecular actions.

We've watched with interest as subsequent developments have allowed RoboBee to fly, swim, hover, perch and lose its tether. Now it's become the first microrobot to achieve controlled flight using soft artificial muscles.

Impressive research has verified a long-held hypothesis called immune amnesia, demonstrating how infection by the measles virus can remove pre-existing immune system protections, leaving a person vulnerable to other infections for several years.

The ability of jumping spiders to correctly judge the distance of its leaps could mean big things for imaging in small devices, with scientists at Harvard tapping into these skills to develop a new kind of ultra-compact depth-perception sensor.

CRISPR is a powerful gene-editing tool – but it has its own problems too. Now, Harvard and MIT scientists have created a new approach called prime editing, which could correct almost 90 percent of disease-causing genes.

Although lab-grown meat could be a more ethical, eco-friendly alternative to the "real" thing, its texture still leaves something to be desired. That may be about to change, though, thanks to the use of edible gelatin scaffolds.

A landmark new study is strongly linking excessive neural activity with shorter lifespans. The study suggests a protein known to suppress neural excitation affects a number of longevity pathways, effectively slowing the aging process.
