Novel Antibody Platform Tackles Viral Mutations

Mount Sinai Health System — Wed, 23 Oct 2024 11:00:00 EST

Scientists at the Icahn School of Medicine at Mount Sinai, in collaboration with colleagues in the field, have developed an innovative antibody platform aimed at tackling one of the greatest challenges in treating rapidly evolving viruses like SARS-CoV-2: their ability to mutate and evade existing vaccines and therapies. Their findings, including preclinical studies in mice, introduce the Adaptive Multi-Epitope Targeting and Avidity-Enhanced (AMETA) Nanobody Platform, a new antibody approach for addressing how viruses like SARS-CoV-2, which causes COVID-19, evolve to evade vaccines and treatments. Details on the results were published October 23 in the journal Cell.

Researchers Succeed in Taking 3D X-ray Images of a Skyrmion

Lawrence Berkeley National Laboratory — Tue, 22 Oct 2024 11:00:00 EST

A difficult-to-describe nanoscale object called the magnetic skyrmion might one day yield new microelectronic devices that can do much more--for example, massive data storage--all while consuming much less power. But researchers need a more detailed understanding of skyrmions if they are ever to be used reliably in computational devices, including quantum computers. Berkeley Lab scientists led a project to make 3D X-ray images of skyrmions that can characterize or measure the orientations of spins inside the whole object.

NUS Researchers Develop Revolutionary Technology to Unravel Complex Protein Interactions That Could Transform Cancer Diagnostics

National University of Singapore (NUS) — Sun, 29 Sep 2024 22:05:26 EST

A team of researchers from NUS Institute for Health Innovation & Technology (iHealthtech), led by Associate Professor Shao Huilin and Associate Professor Brian Lim, has developed a first-of-its-kind technology to map out diverse protein interactions in cells using DNA barcodes. The technology, dubbed TETRIS, can explicitly identify and quantify multiple interacting partners in large protein assemblies. By capturing the complex hierarchy of protein interactions within tumour cells, the technology uncovers detailed molecular mechanisms driving disease progression. This enables more precise diagnostics, allowing for the accurate sub-typing of cancers and the identification of aggressive forms of the disease in just a few hours, which was not possible previously.
