New research found that using focused-ultrasound-mediated liquid biopsy in a mouse model released more tau proteins and another biomarker into the blood than without the intervention. This noninvasive method could facilitate diagnosis of neurodegenerative disorders, the researchers said. Source: Washington University in St. Louis/Science Daily

A soldier suffers a serious gunshot wound on a remote battlefield or a machinist has a work accident and gets stuck in traffic on the way to the hospital. Secondary, uncontrolled bleeding from traumatic injury is a leading cause of death for Americans ages one to 46. Chemical and biomedical engineers plan to change that with a novel microneedle patch that can immediately stop bleeding after injury. Source: Penn State/Science Daily

Researchers have developed a new tool and technique that uses 'vortex ultrasound' -- a sort of ultrasonic tornado -- to break down blood clots in the brain. The new approach worked more quickly than existing techniques to eliminate clots formed in an in vitro model of cerebral venous sinus thrombosis (CVST).

Using a specialized MRI sensor, engineers have shown that they can detect light deep within tissues such as the brain. Source: Massachusetts Institute of Technology/Science Daily

Researchers report that they have developed a new experimental pipeline to combine bacterial therapy with current cancer drugs. Their study, which explores resistance to bacterial therapy at the molecular level, has achieved better treatment efficacy without additional toxicity in laboratory models.

A team of engineers has developed a photoacoustic patch that can monitor biomolecules in deep tissues, including hemoglobin. It can perform 3D mapping of hemoglobin with a submillimeter spatial resolution in deep tissues, down to centimeters below the skin, versus other wearable electrochemical devices that only sense the biomolecules on the skin surface.

A new website from NIH is allowing people in the United States to anonymously report their rapid test results. Sharing your results on the site, called MakeMyTestCount.org, bolsters the information public health departments have about whether or not the COVID is spreading. Source: VeryWell Health

Researchers led a large-scale global machine learning effort to securely aggregate knowledge from brain scans of 6,314 glioblastoma (GBM) patients at 71 sites around the globe and develop a model that can enhance identification and prediction of boundaries in three tumor sub-compartments, without compromising patient privacy.

Biomedical and genetic engineers have designed a small fluorescent protein that emits and absorbs light that penetrates deep into biological tissue. Tailored to wavelengths in the near-infrared (NIR) spectrum, this protein can help researchers capture deeper, cleaner, more precise biomedical images. Source: Duke University/Science Daily

Researchers have applied emerging electronic tattoo (e-tattoo) technology to the tricky task of measuring stress levels by attaching a device to people's palms. Source: University of Texas at Austin/Science Daily
