Biodegradable computer chips made almost entirely from wood

As electronic devices are becoming outdated at an increasingly fast pace, e-waste continues to be a huge problem. That's why scientists from the University of Wisconsin-Madison have started producing "wooden" semiconductor chips that could almost entirely biodegrade once left in a landfill. As an added bonus, the chips are also flexible, making them prime candidates for use in flexible electronics.

Functioning synthetic blood vessels become the real thing

When a vein or artery gets seriously blocked, a common course of action involves replacing it with part of another blood vessel harvested from elsewhere in the patient's body. While 3D-printed and lab-grown blood vessels show promise as alternatives, scientists from the Vienna University of Technology and Vienna Medical University have developed another option – polymer fabric vessels that transform into biological ones, once implanted.

Tiny robotic hand-like grippers dissolve in the body after performing task

Creating swarms of soft, robotic hands that can safely dissolve within a living body once they've performed surgical procedures or delivered drugs just got a step closer thanks to work done by John Hopkins University scientists. They've created minute biodegradable microgrippers by adding stiff polymers containing magnetic nanoparticles to soft hydrogels, allowing them be magnetically guided to any location in the body.

Vaccine self-assembles into 3D structure to better fight cancer and deadly infections

Scientists have had some success activating the body's immune system to take the fight to cancer and other diseases, a process known as immunotherapy. Now, a new method developed by researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University could advance this form of treatment even further. The technique involves the injection of biomaterials that assemble into 3D scaffolds inside the body to accommodate huge amounts of immune cells, a process that could trigger an attack on deadly infections ranging from HIV to cancer to Ebola.

Electronic implants treat staph infections, and then dissolve

Imagine if there were a remote-control electronic device that could be implanted at an infection site, where it would treat the infection by heating or medicating the affected tissue. While it might be very effective, subsequent infections could result if surgeons went in to remove it, or even if they just left it in place. That's why scientists from Tufts University and the University of Illinois at Champaign-Urbana have developed infection-treating implants that simply dissolve into the body once they've served their purpose.

Goodwell open-source toothbrush is built to last a lifetime

If we assume everybody is acting on the advice of their dentist and replacing their toothbrush every few months, then there's likely a lot of frayed bristles laying in landfill right now. But must our dental care devices take on such as short lifespan? The Goodwell open-source toothbrush is a modern take on oral hygiene, built from eco-friendly materials and made to last until you haven't got any teeth left to brush. Read More
