It turns out that your chronological age really is just a number. What’s more important for knowing disease risk is the biological age of each of your organs

An electrode inspired by soft robotics could provide less invasive brain-machine interfaces

As few as 15 percent of people who would benefit from hearing aids use them

Companies are recruiting black soldier flies and mealworms as a protein source in animal feed, fertilizer, biofuels and even as ingredients for burgers and shakes

New technology combines electricity and drugs to stimulate healing of tenacious wounds

Magnetic stimulation of brain regions could help people stop smoking, but researchers are still learning how to deliver the treatment effectively

A state of torpor might rescue oxygen-starved brain cells or aid extended human space missions

A device provides a connection between the brain and spinal cord, allowing thought to control movement

A wireless device worn on the face or lip can produce fragrances such as lavender and green tea in a virtual world

A robotic finger’s supersensitive touches could probe inside body parts and circuits

Bioengineers are drawing on rapidly evolving machine-learning tools, deep reservoirs of data and the firepower of a program called AlphaFold2 to pursue more sophisticated de novo protein designs

A new material was used in a simple snail robot, but it could one day make artificial nervous systems for more complex machines
