The First Living Robots
A book is made of wood. But it is not a tree. The dead cells have been repurposed to serve another need. Now a team of scientists has repurposed living cells—scraped from frog embryos—and assembled them into entirely new life-forms. These millimeter-wide "xenobots" can move toward a target, perhaps pick up a payload (like a medicine that needs to be carried to a specific place inside a patient)—and heal themselves after being cut.

Bioelectric Stimulation to Clear Skin Lesions
The delivery of ultrashort pulses of electrical energy represents a promising nonthermal, nonscarring method of inducing regulated cell death in common skin lesions.

Noninvasive neuromodulation to treat obesity
Novel approaches that have been tested to treat obesity include noninvasive neuromodulation techniques such as transcranial direct current stimulation. Studies performed to date have suggested that this method does in fact help reduce appetite, food intake and body weight, but only in some subjects.

Flexible electronics and smart bandages are key to cost savings
Flexible electronics and smart bandages are key to cost savings in the future of advanced wound care. Advanced wounds, referring to those that are non-healing for more than 4 weeks, are on the rise around the world. This is because there are an increasing number of people with poor wound healing ability, including the rising number of elderly people over 65 years of age, and the rising number of people with Type 2 diabetes.

Wearable bioreactor induced partial limb regeneration
Researchers have found that delivering progesterone to an amputation injury site can induce the regeneration of limbs in otherwise non-regenerative adult frogs—a discovery that furthers understanding of regeneration and could help advance treatment of amputation injuries.

Growing functioning human neural networks in 3D from stem cells
A team of researchers has developed three-dimensional human tissue culture models for the central nervous system that mimic structural and functional features of the brain and demonstrate neural activity sustained over a period of many months.

Ionic Materials (IM) is a US-based start-up developing a solid polymer electrolyte for Li-ion batteries. Founded in 2011 by Mike Zimmerman, serial entrepreneur and professor at Tufts University, in 2018 the company raised $65M in a Series C funding round that included Hyundai, Renault-Nissan, A123 Systems, Total, and Hitachi Chemical, among other investors.

Smart bandages monitor and tailor treatment for chronic wounds
A team of engineers has developed a prototype bandage designed to actively monitor the condition of chronic wounds and deliver appropriate drug treatments to improve the chances of healing. While the lab-tested bandages remain to be assessed in a clinical context, the research is aimed at transforming bandaging from a traditionally passive treatment into a more active paradigm to address a persistent and difficult medical challenge.

Teaching robots to sort out their issues
Robots can help do a lot of things - assemble cars, search for explosives, cook a meal or aid in surgery. But one thing they can't do is tell you how they're doing - yet.

Teaching robots manners
Advances in artificial intelligence are making virtual and robotic assistants increasingly capable in performing complex tasks. For these "smart" machines to be considered safe and trustworthy collaborators with human partners, however, robots must be able to quickly assess a given situation and apply human social norms.

Stretchy optical fibers for implanting in the body
Researchers have developed a biocompatible and highly stretchable optical fiber made from hydrogel — an elastic, rubbery material composed mostly of water. The fiber, which is as bendable as a rope of licorice, may one day be implanted in the body to deliver therapeutic pulses of light or light up at the first sign of disease.

Smart sensors can be sutured into tissue
For the first time, researchers have integrated nano-scale sensors, electronics and microfluidics into threads - ranging from simple cotton to sophisticated synthetics - that can be sutured through multiple layers of tissue to gather diagnostic data wirelessly in real time.
