Tissue-engineered implants provide new hope for vocal injuries

New technology from Purdue University and Indiana University School of Medicine innovators may one day help patients who suffer devastating vocal injuries from surgery on the larynx. A collaborative team consisting of Purdue biomedical engineers and clinicians from IU has tissue-engineered component tissue replacements that support reconstruction of the larynx.

Tool that more efficiently analyzes ocean color data will become part of NASA program

Researchers at Stevens Institute of Technology have developed a new machine learning-powered platform, known as OC-SMART, that can process ocean color in satellite images 10 times faster than the world's leading platform. The work, which will be adopted by NASA, is one of the first machine learning-based platforms in ocean color analysis that can process both coastal and open ocean regions...

Treating rheumatoid arthritis with micromotors

Rheumatoid arthritis is a chronic inflammatory disorder marked by joint pain, swelling and damage. Although medications, such as steroids, anti-inflammatory drugs and immunosuppressants, can help slow joint destruction and relieve pain, they have side effects and aren't completely successful. Now, researchers reporting in ACS' Nano Letters have developed magnesium-based micromotors propelled by...

Twin atoms: A source for entangled particles

One of the most important phenomena in quantum physics is entanglement - used for quantum krypography, quantum computers and many other applications. While it is easy to create pairs of entangled photons, it is much harder to create entangled atoms in a well-defined way. This has now been made possible using an experimental setup developed at TU Wien (Vienna).

UK police find missing Brits quicker, at home or abroad.

Research by the Centre for the Study of Missing Persons (CSMP) at the University of Portsmouth also shows they were likely to be missing for much longer than if they'd disappeared in the UK. The study found that British people who vanish abroad tend to be missing for extended periods, on average 134 days. This compares with 88 percent of people who go missing in the UK being found within the first...

Understanding the evolution of SARS and COVID-19 type viruses

As COVID-19 sweeps the world, related viruses quietly circulate among wild animals. A new study shows how SARS-CoV-2, the virus that causes COVID-19, and SARS-CoV-1, which caused the 2003 SARS outbreak, are related to each other. The work, published recently in the journal Virus Evolution, helps scientists better understand the evolution of these viruses, how they acquired the ability to infect...

Unequal parenthood impacts may explain academia's publication gender gap

Parenthood leads to greater reductions in short-term research productivity for mothers across three disciplines than for fathers, largely explaining the publication gender gap between women and men in academia, according to an analysis of survey data from 3,064 tenure track faculty at PhD-granting universities in the US and Canada.

Vaginal pessaries prove effective in treating pelvic organ prolapse long-term

CLEVELAND, Ohio (Feb 24, 2021)--The aging population combined with increasing obesity rates has resulted in more women experiencing pelvic organ prolapse. Common treatment options include pelvic reconstructive surgery or the use of pessaries to prop up descending organs. A new study evaluated the long-term effectiveness of pessaries, as well as reasons why women discontinued their use. Study...

What to do when a mammogram shows swollen lymph nodes in women just vaccinated for COVID

When women undergo breast imaging shortly after receiving a COVID-19 vaccine in the arm, their tests may show swollen lymph nodes in the armpit area. Radiologists at Massachusetts General Hospital say that this is usually a normal finding, and if there are no other concerns, no additional imaging tests are needed unless the lymph nodes remain swollen for more than six weeks after vaccination. The...

Yale scientists capture the choreography of a developing brain

The formation of a brain is one of nature's most staggeringly complex accomplishments. The intricate intermingling of neurons and a labyrinth of connections also make it a particularly difficult feat for scientists to study.Now, Yale researchers and collaborators have devised a strategy that allows them to see this previously impenetrable process unfold in a living animal -- the worm...

Contact cravings

After months of social distancing, it’s not surprising that many people have felt starved for human companionship. Now a study from MIT has found that to our brains, the longings we feel during isolation are indeed similar to the food cravings we feel when hungry. After subjects endured one day of total isolation, looking at pictures of people having fun together activated the same brain region...

Media Lab’s new head

After a worldwide search that turned up 60 candidates, the MIT Media Lab has announced that Dava Newman, SM ’89, SM ’89, PhD ’92, an MIT professor of astronautics, will become its new director on July 1. Newman, whose work has integrated engineering, design, and biomedical research with an eye to improving human performance in space, is well known for developing the BioSuit, an advanced...

Automatic for the robots

Robot design is usually a painstaking process, but MIT researchers have developed a system that helps automate the task. Once it’s told which parts you have—such as wheels, joints, and body segments—and what terrain the robot will need to navigate, RoboGrammar is on the case, generating optimized structures and control programs. To rule out “nonsensical” designs, the researchers...
