A study led by bioengineers at the University of California San Diego sheds new light on how a type of heart valve disease, called aortic valve stenosis, progresses differently in males and females. The research reveals that this sex-based difference can be traced to a gene on the Y chromosome.  Source: MedicalXpress.com

For decades, scientists have relied on electrodes and dyes to track the electrical activity of living cells. Now, engineers at the University of California San Diego with NIBIB funding have discovered that quantum materials just a single atom thick can do the job—using only light.

In recent years, scientists and engineers have looked to muscles as potential actuators for “biohybrid” robots — machines powered by soft, artificially grown muscle fibers. Now, MIT engineers with NIBIB funding have developed a method to grow artificial muscle tissue that twitches and flexes in multiple coordinated directions. Source: MIT News

A team of researchers at Case Western Reserve University has discovered that bacteria can invade the brain after a medical device is implanted, contributing to inflammation and reducing the device’s long-term effectiveness.

A team of researchers at the University of Illinois Grainger College of Engineering have conducted a research project that's led to new technology that offers rapid, highly sensitive detection of multi-drug-resistant bacteria and other pathogens at low concentrations. Source: EurekAlert!

The National Institutes of Health (NIH) has selected four finalists with innovative, non-invasive technologies that seek to improve diagnosis of endometriosis.

Positron emission tomography (PET) is a nuclear imaging technique used to diagnose conditions such as cancer. An innovative advance from scientists at St. Jude Children’s Research Hospital is enhancing the technique’s ability to check for signs of neurological disease. The researchers repurposed the drug edaravone, an antioxidant used to treat amyotrophic lateral sclerosis (ALS), as a probe to be used with central nervous system PET imaging. With this technique, the researchers can detect oxidative stress, which leads to brain damage, offering a clear path to detecting neurological conditions.

Cancers occurring in the mouth, nose, and throat are on the rise in the U.S., especially in younger people. A new study provides insights that may eventually help oncologists better predict how the disease will respond to certain therapies, leading to improved survival outcomes for patients.

Two heads are better than one, as the saying goes, and sometimes two instruments, ingeniously recombined, can accomplish feats that neither could have done on its own. For the first time, a hybrid microscope born at the Marine Biological Laboratory (MBL), allows scientists to simultaneously image the full 3D orientation and position of an ensemble of molecules, such as labeled proteins inside cells.  Source: Marine Biological Laboratory at the University of Chicago.
