Material Made from DNA Undergoes Metabolism, Powers Itself

Scientist at Cornell University have developed a remarkable new material, which is made out of DNA and which undergoes metabolism. One of the crucial aspects of life is metabolic activity, which essentially means that large molecules are broken down and small molecules are used to build larger ones. The dynamic material that the Cornell team [&hell (Read more...)

Ultra Cheap Endoscope to Make Cancer Screenings More Common

Conventional endoscopes can get quite pricey these days, sometimes costing more than $100,000 a set. Moreover, they’re expensive to maintain because of intense cleaning regimens that are required to prevent transmission of infections. Engineers at the University of Leeds in the UK are working on bringing the price of endoscopes closer to $50 (Read more...)

Engineered Matrix to Improve T Cell Immunotherapy

Researchers from Johns Hopkins University have developed an “artificial lymph node” to help multiply antigen-specific T cells to fight cancer. They used a hydrogel that contains immunostimulatory antigen-presenting nanoparticles to encourage T cells to proliferate, and have increased activity against specific antigens. Current T-cell ba (Read more...)

First Drug-Free Option for ADHD Cleared in America

For the first time, children in the United States will have a non-drug option for treating attention deficit hyperactivity disorder (ADHD). The FDA just cleared the Monarch external Trigeminal Nerve Stimulation (eTNS) System from NeuroSigma, a Los Angeles, California company, to treat ADHD in kids between 7 and 12 years old. The system has already (Read more...)

New Device Cleans Blood to Treat Preeclampsia

Preeclampsia is one of the most common serious maladies that pregnant women encounter. It is a poorly understood condition with symptoms such as high blood pressure, proteinuria, and headaches, potentially even leading to seizures. The treatment options for preeclampsia are still very limited, mostly confined to hypertension medications, bed rest, (Read more...)

Wearable Epinephrine Injector to Stop Allergic Reactions

People susceptible to acute allergic reactions, particularly children, can find it difficult to keep an epinephrine injector (think EpiPen) on hand. Adrenaline, the common name of epinephrine, has to be delivered quickly before anaphylactic shock sets in, so a team at Rice University have developed a wearable injector that can be used at any time. (Read more...)

3D-Printed Heart From Patient’s Own Tissues

Researchers from Tel Aviv University in Israel have developed a 3D printing approach to create a heart with a patient’s own cells. The investigators used patient-derived cellular and acellular material obtained from fatty tissue, along with a unique bioprinter, to 3D-print a heart. The team isolated cells from a patient tissue sample and used (Read more...)

The Power of Modern Hearing Aids: Interview with Laurel Christensen, Chief Audiology Officer, GN Hearing

Modern hearing aids have to pack a great deal of technology in a tiny package. The batteries, high speed computer chips, speakers, microphones, and antennas have to all fit together and work in unison. They drive multiple sound processing algorithms that can modify how audio is boosted for the unique needs of each individual user. […]
