Sense Diagnostics announces initiation of clinical trial to evaluate a non-invasive brain scanner to monitor intracranial hemorrhage
SENSE device uses low-power tailored radio frequency (RF) pulse to detect changes that may indicate expanding brain bleed
Current standard of care lacks a means to monitor brain injury continuously, non-invasively, in real time, between CT scans
CINCINNATI, OH - March 16, 2021 - Sense Diagnostics, a medical technology company focused on improving outcomes for stroke and brain injury patients, announced the initiation of a multicenter pivotal trial to evaluate the safety and efficacy of a non-invasive brain scanner to monitor intracranial hemorrhage (ICH) in an acute hospital setting. The SENSE device is a headset equipped with antennae that transmit a low-power tailored radio frequency (RF) pulse across the brain and uses an algorithm to detect signal changes that may indicate an expansion in ICH.
Researchers have developed a method, described in APL Bioengineering, that uses machine learning to determine whether a single cell is cancerous by detecting its pH. Their approach can discriminate cells originating from normal tissues from cells originating from cancerous tissues, as well as among different types of cancer, while keeping the cells alive. The method relies on treating the cells with bromothymol blue, a pH-sensitive dye that changes color depending on acidity.

Low doses of propylparaben - a chemical preservative found in food, drugs and cosmetics - can alter pregnancy-related changes in the breast in ways that may lessen the protection against breast cancer that pregnancy hormones normally convey, according to University of Massachusetts Amherst research.
The findings, published March 16 in the journal
Endocrinology, suggest that propylparaben is an endocrine-disrupting chemical that interferes with the actions of hormones, says environmental health scientist Laura Vandenberg, the study s senior author. Endocrine disruptors can affect organs sensitive to hormones, including the mammary gland in the breast that produces milk.

The hummingbird is named after its pleasant humming sound when it hovers in front of flowers to feed. But only now has it become clear how the wing generates the hummingbird s namesake sound when it is beating rapidly at 40 beats per second. Researchers from Eindhoven University of Technology, Sorama, a TU/e spin-off company, and Stanford University meticulously observed hummingbirds using 12 high-speed cameras, 6 pressure plates and 2176 microphones. They discovered that the soft and complex feathered wings of hummingbirds generate sound in a fashion similar to how the simpler wings of insect do. The new insights could help make devices like fans and drones quieter.
