Newly-discovered organelle key to sense of smell
January 6, 2023 -- Sweden’s Umeå Universit said this week that its researchers have discovered a previously unknown component inside nerve cells—an organelle that enables the perception of smell. The discovery, published recently in Nature Communications, may have implications for research on olfactory impairment -- a common COVID-19 symptom. Read More
Immune surprise: alarm protein drives inflammation
December 19, 2022 -- Trinity College scientists have discovered that a key immune alarm protein, previously believed to calm the immune response, actually does the opposite. The study, published December 16 in the journal Science Immunology, advances the understanding of autoimmune disorders and how inflammation is regulated. Read More
Study: Menarini’s CellSearch technology effective in measuring and monitoring CTC levels in multiple myeloma
December 15, 2022 -- Single-cell technology and liquid biopsy developer Menarini Silicon Biosystems on Wednesday announced results from a study published December 7 in Cancer Discovery demonstrating that the enumeration and genomic characterization of circulating tumor cells (CTCs) at varying stages of multiple myeloma (MM) is invaluable in predicting disease aggressiveness and pathology.

Oxytocin could be the key to neural plasticity: study
December 12, 2022 -- Researchers have learned that the peptide oxytocin could promote the growth of new neurons to repair damaged tissue and thus may contribute to neural circuit plasticity, opening the door to new ways to improve neurological conditions. Read More
NIH awards $1.8M grant to study long-term memory
December 12, 2022 -- The National Institute of General Medical Sciences, one of the National Institutes of Health (NIH), awarded a University of Massachusetts Amherst scientist $1.8 million to study how long-term memory works at a molecular level. Read More
Cellular nano-chamber directs tubulin protein folding: study
December 9, 2022 -- U.S. Department of Energy and Stanford University researchers have revealed how tiny cellular machines -- called chaperonins -- direct the folding of proteins into building blocks that provide essential cellular scaffolding and transport. Read More
Optogenetics-based tool manipulates neuron excitability
December 9, 2022 -- Harvard University and Massachusetts Institute of Technology researchers have devised a new technique to achieve long-term changes in neuron activity using light exposure. Their research, published on December 7 in the journal Science Advances, may help establish causality between neuron excitability and behavior, advancing the field of optogenetics. Read More
Scientists create cell atlas of developing human lung
December 9, 2022 -- Researchers from the Wellcome Sanger Institute, EMBL’s European Bioinformatics Institute, the Gordone Institute at the University of Cambridge, and collaborators have created a spatiotemporal cell atlas of the developing human lung. From the mapping, they have identified 144 cell states in the early stages of life and their interactions in new detail. Read More
New microscopy captures 3D images of whole organisms
December 9, 2022 -- A new microscopy technique enhances biomedical research by capturing dynamic 3D images across larger areas while maintaining cellular resolution in all three dimensions. A study, published on December 8 in the journal Optica, provides new views of cells interacting in their natural state, potentially facilitating the development of new disease treatments. Read More
Glowing protein allows deeper looks at living tissues
December 7, 2022 -- Duke University and Albert Einstein College of Medicine researchers have designed a small fluorescent protein that absorbs and emits wavelengths of near-infrared light that penetrate deep into living tissue. Their technique, outlined December 1 in the journal Nature Methods, captures detailed high-resolution biomedical images. Read More
