In order to observe specific behaviors, scientists will often rig wild animals up with tiny cameras or other "bio-logging" devices. A new technology could help these tools gather more data, by only fully powering up when needed.

Ordinarily, when using an off-the-shelf 3D printer, it's quite difficult to print a single object that incorporates multiple materials. An experimental new system could make it easier, though, by utilizing a "programmable filament."

Whether it's entangling marine animals or forming giant floating "garbage patches," oceanic plastic waste is a huge problem. There may be new hope however, in the form of what is claimed to be a better type of marine-biodegradable plastic.

In what is a world-first and potentially the dawn of a new medical technology to treat damaged hearts, scientists in Japan have succeeded in transplanting lab-grown heart cells into human patients for the first time ever.

We've already seen tactile-feedback displays that convey information by applying tiny vibrations to the user's fingertips. An experimental new technology takes a different approach, however – it gets sticky in select areas.

The 2019 Nobel Prize in Chemistry has been awarded to three scientists for the invention and development of the lithium-ion battery.

Induced pluripotent stem cells (iPSCs) hold all kinds of potential in the world of regenerative medicine. One of the many possibilities could be repairing damaged hearts, something that will soon be put to the test for the first time ever in newly approved clinical trials in Japan.

Some theories suggest there could be many more dimensions that we’re unaware of, mostly because they’re imperceptibly tiny. Now researchers have taken the search for extra dimensions down to the nanoscale, using a neutron beam to study gravitational forces more precisely than ever before.

Scientists have developed a nanofiber "nerve-wrap" mesh that could be used to treat conditions such as carpal tunnel syndrome. It takes the form of a flat sheet that is surgically wrapped around the injured nerve to form a sleeve, which releases vitamin B12.

When silicon wafers are cut from sheets of silicon, a lot of sawdust is produced. Ordinarily, that material is discarded. Thanks to research currently being conducted by Japan's Tohoku University and Osaka University, however, it may soon find its way into high-performing lithium-ion batteries.

A team of scientists from Osaka University and Tohoku University has developed a new robotic microscope that automatically tracks moving objects as part of a study of brain activity.​

An international team of scientists has used human stem cells to build layers of eye tissue that was then implanted into rabbits to restore vision. With promising early results, the researchers say their findings could usher in trials where such transplantations are put to the test in humans.
