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.

The 2019 Nobel Prize in Medicine has been awarded to William Kaelin, Peter Ratcliffe and Gregg Semenza for uncovering how cells adapt to low oxygen.

American scientists have created a "Tunabot," that they claim can match the swimming speed of an actual tuna.

A new supercooling technique could greatly improve transplantation outcomes by taking the organs into the realm of subzero temperatures for the first time.

Researchers have developed ultra-gentle robotic grippers that can grasp and release jellyfish and other very soft marine animals without harming them.
