CVD deaths undergo largest single-year increase since 2015 January 25, 2023 -- The American Heart Association's report "Heart Disease and Stroke Statistics—2023 Update" outlines the most significant single-year increase in cardiovascular disease (CVD) deaths in the U.S. since 2015.Read More
T-cell therapy fights viral infections following stem cell transplants January 13, 2023 -- Baylor College of Medicine and Washington University School of Medicine researchers studied posoleucel, an investigational off-the-shelf T-cell therapy that simultaneously targets six different viruses. The results, published January 11 in the journal Clinical Cancer Research, showed promising antiviral efficacy and safety in a phase II clinical trial of patients who had undergone stem cell transplantation to treat blood diseases including cancer.Read More
New probe measures cell stiffness and traction January 25, 2023 -- University of Illinois scientists have developed a tiny mechanical probe that can measure the inherent stiffness of cells and tissues, as well as the internal forces that cells generate and exert upon one another. It is the first probe able to quantify both properties, according to its developers.Read More
Artificial nerve cells closely mimic biological ones January 17, 2023 -- Researchers at Sweden’s Linköping University have created an artificial neuron that closely mimics the characteristics of biological nerve cells. They describe the work in a study, published recently in Nature Materials, indicating that the artificial neuron can stimulate natural nerves, making it a promising technology for various medical treatments.Read More
mRNA COVID-19 booster rates low among immunocompromised January 20, 2023 -- Researchers have found low adherence to the Centers for Disease Control and Prevention's mRNA monovalent COVID-19 booster recommendations among immunocompromised individuals.Read More
Long COVID risk significantly higher in unvaccinated: Study January 18, 2023 -- A cohort study found that the risk of developing persistent post–COVID-19 symptoms, or long COVID, was significantly higher in unvaccinated participants and those initially hit harder by the virus. The research, published Wednesday in JAMA Network Open, showed that six months after onset, long-COVID participants had a significantly higher risk of pulmonary, diabetes, neurological, and mental health issues than they did preinfection.Read More
'Living medicine' for drug-resistant lung infections January 19, 2023 -- Researchers have engineered a bacterium that serves as a “living medicine” to treat antibiotic-resistant lung infections -- the leading cause of hospital mortality. The research, published January 19 in the journal Nature Biotechnology and supported through CaixaResearch Health, focused on the antibiotic-resistant bacterium Pseudomonas aeruginosa, a common source of difficult-to-treat hospital infections.Read More
AI tool makes speedy gene editing possible January 26, 2023 -- Researchers have designed an artificial intelligence (AI) program that may enable the production of customizable proteins called zinc fingers to treat diseases by turning genes on and off. The research published on January 26 in Nature Biotechnology may accelerate large-scale gene therapy development.Read More
DNA sequencing method offers peek into genomic black box January 23, 2023 -- University of Cambridge researchers have outlined a new DNA sequencing method that detects where and how small molecule drugs interact with a targeted genome. The research, published on January 23 in Nature Biotechnology, allows precise mapping of drug-genome binding sites, potentially enabling the development of more effective medications.Read More
Initial colon cancer surgery may not be best course January 11, 2023 -- Southern China researchers unexpectedly found pre-surgery immunotherapy for a common type of colorectal cancer even more effective at early and mid-stages than its previously known high success rate in the metastatic stage of the disease. The study, published January 11 in JNCCN - Journal of the National Comprehensive Cancer Network, found that immune checkpoint programmed cell death 1 (PD-1) inhibitor treatment prior to surgery was significantly effective for patients with certain types of colorectal cancer.Read More
Wyss Institute launches RNA therapeutics startup EnPlusOne Biosciences December 21, 2022 -- Wyss Institute at Harvard University has partnered with Northpond Labs to launch EnPlusOne Biosciences. The startup aims to bring versatile, scalable RNA synthesis technology to market, with the goal of unlocking the development of new RNA drugs, vaccines, and gene-editing therapies.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
Senescent neuron discovery in brains opens path for Alzheimer's drug development December 2, 2022 -- Scientists at the Salk Institute for Biological Studies have found that neurons from people with Alzheimer's disease show deterioration and undergo a late-life stress process called cellular senescence, while senescent cells could be a way to slow neuroinflammation and neurodegeneration.Read More
