Researchers produce first laser ultrasound images of humans

Technique may help remotely image and assess health of infants, burn victims, and accident survivors in hard-to-reach places. Jennifer Chu | MIT News OfficeDecember 19, 2019 For most people, getting an ultrasound is a relatively easy procedure: As a technician gently presses a probe against a patient’s skin, sound waves generated by the probe travel […]

Producing better guides for medical-image analysis

Model quickly generates brain scan templates that represent a given patient population. Rob Matheson | MIT News OfficeNovember 26, 2019 MIT researchers have devised a method that accelerates the process for creating and customizing templates used in medical-image analysis, to guide disease diagnosis.   One use of medical image analysis is to crunch datasets of […]

Study paves way to better understanding, treatment of arthritis

NOVEMBER 25, 2019 by Steve Lundeberg, Oregon State University Oregon State University research has provided the first complete, cellular-level look at what’s going on in joints afflicted by osteoarthritis, a debilitating and costly condition that affects nearly one-quarter of adults in the United States. The study, published today in Nature Biomedical Engineering, opens the door to better […]

Heating techniques could improve treatment of macular degeneration

NOVEMBER 24, 2019 by American Physical Society Age-related macular degeneration is the primary cause of central vision loss and results in the center of the visual field being blurred or fully blacked out. Though treatable, some methods can be ineffective or cause unwanted side effects. Jinglin Huang, a graduate student in medical engineering at Caltech, suggests […]

Shaking head to get rid of water in ears could cause brain damage, physicists find

NOVEMBER 24, 2019 by American Physical Society Trapped water in the ear canal can cause infection and even damage, but it turns out that one of the most common methods people use to get rid of water in their ears can also cause complications. Researchers at Cornell University and Virginia Tech show shaking the head to […]

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 […]

What survives, thrives and dominates over a thousand generations? The answer might be even more complex than thought

NOVEMBER 13, 2019 by Harvard University Aa team of scientists, led by Harvard researchers, has used a new method of DNA “re-barcoding” to track rapid evolution in yeast. The new approach, published in Nature, advances the field of organismic and evolutionary biology and holds promise for real-world results. The potential impact of the work can be illustrated […]

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 […]

Biologists build proteins that avoid crosstalk with existing molecules

Engineered signaling pathways could offer a new way to build synthetic biology circuits. Anne Trafton | MIT News OfficeOctober 23, 2019 Inside a living cell, many important messages are communicated via interactions between proteins. For these signals to be accurately relayed, each protein must interact only with its specific partner, avoiding unwanted crosstalk with any […]

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 […]
