Camera Measures Blood Pressure with Quick Look

At the University of South Australia, researchers designed a system that allows them to measure a patient’s blood pressure with a camera. The camera visualizes the patient’s forehead and focuses on two regions in particular to optically determine photoplethysmographic signals that AI algorithms then convert to blood pressure data. The r (Read more...)

Diabetes Management Tech for Type II patients: Interview with Jeffrey Brewer, CEO of Bigfoot Biomedical

Bigfoot Biomedical, a medtech company based in California, has developed the Bigfoot Unity System, a diabetes management technology for patients on multiple daily injection therapy. The system uses continuous glucose monitoring data and doctor recommendations to provide insulin dose recommendations, helping patients to avoid uncertainty. The compan (Read more...)

Modified mRNA Demonstrates 10-Fold Protein Production

Scientists at Hong Kong University of Science and Technology came up with a technique to increase the efficiency and potentially the efficacy of mRNA therapeutics. mRNA molecules have what is called a poly-A tail, which is basically a string of adenine nucleotides at one end. These researchers discovered that by replacing some of these nucleotides (Read more...)

Toolbox to Study Ligand Binding for Enhanced Treatments

Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have developed a DNA toolbox that allows researchers to explore binding interactions between ligands and their respective receptors based on receptor density and arrangement. The basis for many pharmacological interactions between drugs and cells, and indeed (Read more...)

Ferrobot Swarms for Rapid Viral Testing

At the University of California Los Angeles, scientists have developed a handheld lab kit that can conduct automated pooled testing for viral diseases, including COVID-19. The technology consists of a microfluidic platform that relies on swarms of magnetic discs, which the researchers have termed “ferrobots”, to shuttle samples through (Read more...)

Making Tumors Tastier for the Immune System

Researchers at The University of Texas MD Anderson Cancer Center have developed a nanotechnology platform that can make cancer cells more vulnerable to immune attack in the body. The researchers call their system the bispecific tumor-transforming nanoconjugate (BiTN) platform. The idea is to make solid tumors more appealing for the immune system by (Read more...)

Device Measures Hemoglobin More Accurately in Dark Skin

Researchers at the University of Texas at Arlington, in collaboration with Shani Biotechnologies, a local firm, have created a point-of-care device that can accurately measure hemoglobin levels and perform pulse oximetry in individuals with dark skin. At present, methods to determine hemoglobin levels at the point of care, such as pulse oximetry, a (Read more...)

Improved Membrane Coating for Anti-Cancer Nanoparticles

Scientists at the University of Eastern Finland have developed a technique that lets them improve the coating of nanoparticles when using cell membranes. Cell membranes offer a lot of benefits as a coating for synthetic nanoparticles, including shielding from the immune system, prolonged circulation times and improved tumor accumulation. However, c (Read more...)

Magnetic Bacteria Target Tumors

Scientists at ETH Zurich in Switzerland have unveiled a technique that weaponizes bacterial cells against tumors. The approach involves using bacteria called Magnetospirillum that are naturally magnetic by virtue of the iron oxide particles they contain. The researchers use a rotating magnetic field applied at the tumor location from outside the bo (Read more...)

3D Bioprinted Breast Tumors for Immunotherapy Testing

A team of scientists at Penn State has bioprinted breast tumor mimics with significant complexity, including a form of vascularization and the ability to precisely place cells in certain locations within the construct. The scientists used a technique called aspiration-assisted bioprinting to achieve this. With many anti-cancer therapies failing at (Read more...)

Neck Sensor Helps Masked Clinicians Communicate

Researchers at Pohang University of Science & Technology in South Korea developed an auditory sensor that lets people wearing face masks, such as clinicians, to communicate more easily. The device is essentially a wearable microphone that picks up the vibrations of the skin in the neck that occur when someone talks. The researchers hope that [& (Read more...)

mRNA Therapy Prevents COVID Virus Entering Cells

Scientists at Oregon State University have developed a new treatment for COVID-19. The technology is based on mRNA, which has also been put to good use in COVID-19 vaccines. However, in this instance, the delivered mRNA encodes for human angiotensin-converting enzyme 2 (hACE2), which is the binding site for SARS-CoV-2 on airway cells. The lipid [&h (Read more...)

Screening App to Diagnose Parkinson’s, COVID-19 from Voice

Researchers at RMIT University in Melbourne, Australia, have developed an app that is intended to provide early diagnosis for Parkinson’s disease and severe COVID-19. The artificial intelligence-powered technology works by analyzing voice recordings, having previously been trained to recognize the vocal hallmarks of these diseases by listenin (Read more...)
