Blurring lines between man and machine.

A breakthrough has made way for a new paradigm in bioelectronics. Earlier, it took the implantation of physical objects to initiate electronic processes in the body. Humans have incorporated technology to enhance the human experience and take charge of their evolution. They’ve also integrated devices within them that could alternately function as organs when biological tissues fail.

Scientists have now developed a viscous gel that will be enough in the future.

Northwestern scientists have created a groundbreaking medical device with the potential to revolutionize healing: an electrotherapy patch that accelerates wound recovery and safely self-dissolves when no longer necessary.

A precise replica of the patient’s heart is created as a soft, flexible shell.

MIT engineers’ newly developed robotic heart will help doctors adjust therapies to individuals’ unique heart structures and functions. The personalized 3D-printed heart can control and imitate the patient’s capacity to pump blood.

The days of ripping off a Band-Aid could soon be in the past, with scientists creating a new affordable, flexible electronic covering that not only speeds and wirelessly monitors healing but performs a disappearing act by being harmlessly absorbed into the body when its job is done.

“Although it’s an electronic device, the active components that interface with the wound bed are entirely resorbable,” said Northwestern University’s John A. Rogers, who co-led the study. “As such, the materials disappear naturally after the healing process is complete, thereby avoiding any damage to the tissue that could otherwise be caused by physical extraction.”

For the first time, scientists have used machine learning to create brand-new enzymes, which are proteins that accelerate chemical reactions. This is an important step in the field of protein design, as new enzymes could have many uses across medicine and industrial manufacturing.

“Living organisms are remarkable chemists. Rather than relying on toxic compounds or extreme heat, they use enzymes to break down or build up whatever they need under gentle conditions. New enzymes could put renewable chemicals and biofuels within reach,” said senior author David Baker, professor of biochemistry at the University of Washington School of Medicine and recipient of the 2021 Breakthrough Prize in Life Sciences.

As reported Feb, 22 in the journal Nature, a team based at the Institute for Protein Design at UW Medicine devised machine-learning algorithms that can create light-emitting enzymes called luciferases. Laboratory testing confirmed that the new enzymes can recognize specific chemicals and emit light very efficiently. This project was led by two postdoctoral scholars in the Baker Lab, Andy Hsien-Wei Yeh and Christoffer Norn.

The bones of the face and skull can be affected due to a wide range of conditions, including cleft palate defects, traumatic injuries, cancer, and bone loss from dentures. Although bone replacements are routinely used to regenerate the missing tissue, they are vulnerable to bacterial infection. In a new study, researchers investigated whether manuka honey, made from tea trees, can be used to resist bacterial infection and promote bone growth.

Bone implants account for 45% of all hospital-contracted infections, impeding healing. Typically, these implants are made from biomaterials that contain extracellular matrix components—molecules that provide structural support to cells. However, researchers commonly use metal implants or synthetic polymers to study bone defects and infections. Therefore, there is a gap in the understanding of how biomaterials behave in response to infection.

“Imagine a metal versus something soft and porous that is made up of extracellular matrix components. They have very different characteristics,” said Marley Dewey, a former graduate student in the Harley lab and the first author of the paper. “Using our scaffolds, this is the first paper to look at how these materials become infected.”

Apple Inc. has a moonshot-style project underway that dates back to the Steve Jobs era: noninvasive and continuous blood glucose monitoring.

Scientists continue to make intriguing breakthroughs that could help reshape our lives. This time, a group of scientists managed to create a shape-shifting liquid metal that can transition between the solid and liquid state. The new liquid is reminiscent of the liquid shapeshifting seen in 1991’s Terminator 2, and the scientists even tested it by having it escape a cage.

The scientists published a paper on the new shape-shifting liquid in the journal Matter. In it, they discuss how they created the metal and the rigorous tests they put it through. For the most part, the scientists created the liquid in the form of small robots, which they were then able to shift between solid and liquid states to jump, climb, and – as noted above – even ooze out of a cage to freedom.
