Microparticles could help fight malnutrition

New strategy for encapsulating nutrients makes it easier to fortify foods with iron and vitamin A. Anne Trafton | MIT News OfficeNovember 13, 2019 About 2 billion people around the world suffer from deficiencies of key micronutrients such as iron and vitamin A. Two million children die from these deficiencies every year, and people who […]

Double-sided tape for tissues could replace surgical sutures

New adhesive that binds wet surfaces within seconds could be used to heal wounds or implant medical devices. Anne Trafton | MIT News OfficeOctober 30, 2019 Inspired by a sticky substance that spiders use to catch their prey, MIT engineers have designed a double-sided tape that can rapidly seal tissues together. In tests in rats […]

Cell stiffness may indicate whether tumors will invade

Study shows tumors with softer, larger cells at their periphery are more likely to spread; may suggest new route for cancer therapy. Jennifer Chu | MIT News OfficeOctober 21, 2019 Engineers at MIT and elsewhere have tracked the evolution of individual cells within an initially benign tumor, showing how the physical properties of those cells […]

Drug combination reverses hypersensitivity to noise

Findings in mice suggest targeting certain brain circuits could offer new ways to treat some neurological disorders. Anne Trafton | MIT News OfficeOctober 21, 2019 People with autism often experience hypersensitivity to noise and other sensory input. MIT neuroscientists have now identified two brain circuits that help tune out distracting sensory information, and they have […]

Drug that blocks blood vessel growth could treat rare sarcomas

An experimental targeted drug could treat a rare type of cancer usually affecting the limbs, a clinical trial led by The Institute of Cancer Research, London, has shown. OCTOBER 16, 2019 by Institute of Cancer Research The important trial could lead to a much-needed new treatment for patients with alveolar soft part sarcoma (ASPS), which tends […]

Study reveals how mucus tames microbes

Specialized sugar molecules called glycans can disarm opportunistic pathogens and prevent infection. Anne Trafton | MIT News OfficeOctober 14, 2019 More than 200 square meters of our bodies — including the digestive tract, lungs, and urinary tract — are lined with mucus. In recent years, scientists have found some evidence that mucus is not just […]

Seeing the brain’s electrical activity

Fluorescent sensor allows imaging of neurons’ electrical communications, without electrodes. Anne Trafton | MIT News Office Neurons in the brain communicate via rapid electrical impulses that allow the brain to coordinate behavior, sensation, thoughts, and emotion. Scientists who want to study this electrical activity usually measure these signals with electrodes inserted into the brain, a […]

Researchers identify brain protein that promotes maintenance of chronic pain

OCTOBER 12, 2019 by The Mount Sinai Hospital A protein called RGS4 (Regulator of G protein signaling 4) plays a prominent role in the maintenance of long-term pain states and may serve as a promising new target for the treatment of chronic pain conditions, according to research conducted at the Icahn School of Medicine at Mount […]

New method visualizes groups of neurons as they compute

Fluorescent probe could allow scientists to watch circuits within the brain and link their activity to specific behaviors. Anne Trafton | MIT News OfficeOctober 9, 2019 Using a fluorescent probe that lights up when brain cells are electrically active, MIT and Boston University researchers have shown that they can image the activity of many neurons […]

Alzheimer’s plaque emerges early and deep in the brain

Clumps of amyloid protein emerge early in deep regions, such as the mammillary body, and march outward in the brain along specific circuits. David Orenstein | Picower InstituteOctober 8, 2019 Long before symptoms like memory loss even emerge, the underlying pathology of Alzheimer’s disease, such as an accumulation of amyloid protein plaques, is well underway […]
