As people age, they often require bifocals or several pairs of glasses to see objects both near and far. Deep Optics, a technology start-up based in Israel, is working on an alternative: eyeglasses that automatically refocus on any target at which the wearer looks. The “omnifocals” adjust focal length by relying on the interaction between […]

Back in the 1970s, Dr. Steve Rosenberg invented a new field of cancer treatment: immunotherapy, the harnessing of the body’s own immune system to fight tumors. Today, he’s using cutting-edge gene-editing techniques to help turn immunotherapy into the most promising cancer killer of our time. (Video by: Alan Jeffries) more   By clicking on this […]

A few years ago, researchers from Germany and Japan were able to simulate one percent of human brain activity for a single second. It took the processing power of one of the world’s most powerful supercomputers to make that happen. Hands down, the human brain is by far the most powerful, energy efficient computer ever […]

A wearable, graphene-based patch could one day maintain healthy blood glucose levels in people by measuring the sugar in sweat and then delivering the necessary dose of a diabetes drug through the skin (Nat. Nanotech. 2016, DOI: 10.1038/nnano.2016.38). The device takes scientists a step closer to the “coveted prize” in diabetes care: a noninvasive method to monitor […]

Zapping the brain with implanted electrodes may sound like a ridiculously dangerous treatment, but for many patients with Parkinson’s disease, deep brain stimulation (DBS) is their only relief. The procedure starts with open-skull surgery. Guided by MRI images, surgeons implant electrodes into deep-seated brain regions that contain malfunctioning neural networks. By rapidly delivering electrical pulses, […]

Aging insidiously leaves its mark on our brains. With age, our well-oiled neuronal machinery slowly breaks down: gene expression patterns turn wacky, the nuclear membrane disintegrates, and neatly organized molecules inside the cells break out of their segregated compartments, turning the intracellular environment into a maladaptive, muddled molecular soup. more By clicking on this link […]

Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases … but could also be used to create so-called “designer babies.” Doudna reviews how CRISPR-Cas9 works — and asks the scientific community to […]

Johnny Matheny is the first person to attach a mind-controlled prosthetic limb directly to his skeleton. After losing his arm to cancer in 2008, Johnny signed up for a number of experimental surgeries to prepare himself to use a DARPA-funded prosthetic prototype. The Modular Prosthetic Limb, developed by the Johns Hopkins Applied Physics Laboratory, allows […]

Learning to walk again after a traumatic accident is no easy task. One of the hardest things for motor-impaired patients is to generate the correct brain signals to help them recover efficiently. The current best option is physiotherapy: through hard work and frustration, patients gradually relearn the sequence of motor instructions required to sit, walk, stand […]

At thirty-four, Feng Zhang is the youngest member of the core faculty at the Broad Institute of Harvard and M.I.T. He is also among the most accomplished. In 1999, while still a high-school student, in Des Moines, Zhang found a structural protein capable of preventing retroviruses like H.I.V. from infecting human cells. The project earned […]
