New Cell Type in Thymus Uncovered
2023-09-12
Researchers from UC Riverside School of Medicine collaborated with researchers at the Weizmann Institute of Science in Israel and uncovered a new type of cell in the thymus which is responsible for the production and maturation of immune cells. The findings are published in Nature in an article titled, “Thymic mimetic cells function beyond self-tolerance.”
DNA Nanoball Method Detects SARS-CoV-2 with Simple Electronic Device
2023-09-12
The sensing of these micrometer-sized DNA amplifications can be integrated into a standalone device that would provide an inexpensive (<$5), sensitive (10 target copies), and rapid test (<1 hour) Since the beginning of the COVID-19 pandemic, many researchers have joined in developing methods to create scalable detection methods for SARS-CoV-2. As of today, 770,437,327 confirmed cases of COVID-19, including 6,956,900 deaths, have been reported to the World Health Organization (WHO).
Genomic Sequencing Innovations Critical for Battling Future Pandemics
2023-09-12
Genomic sequencing had a huge impact on the global response to COVID-19, and the technology has improved as more researchers put it to use. To better respond to the next pandemic, scientists need to build on that knowledge while also recognizing the gaps in our capabilities that remain, according to an essay, “Towards a post-pandemic future for global pathogen genome sequencing” published in PLOS Biology.
New Swine Flu Strains Raise Concerns about Pandemic Risks
2023-09-12
Scientists from Duke-NUS Medical School and elsewhere have identified several novel strains of swine flu viruses circulating in Cambodian pigs that pose a potential pandemic risk. The new strains include viruses that have jumped from humans to pigs and some strains with genes that originate from North America. The findings point to a need for stronger surveillance methods to identify new viruses and assess their transmission risks before they become a major threat.
Carl Icahn States His Case for Change at Illumina on “Close to the Edge”
2023-09-12
Activist investor Carl C. Icahn has made a lot of news over the past nearly two months by launching a proxy campaign to change Illumina’s board and management, and through that, the company’s direction. For more than a month, Icahn has offered persistent criticism of Illumina’s current board led by chairman John W. Thompson, and the company’s management led by CEO Francis deSouza.
Shorter Telomeres Linked to Higher Risk of Dementia
2023-09-12
Shorter telomeres on the ends of white blood cell chromosomes may signal a heightened dementia risk, suggest the results of a large, long-term study by researchers at Hangzhou Normal University, Zhejiang University School of Medicine, and Capital Medical University. The team’s analysis of leukocyte telomere length (LTL) data and electronic health records from more than 400,000 U.K. Biobank participants found that shorter LTL was associated with a higher risk of dementia and Alzheimer’s disease
New Indicators of Health, Disease, and Aging Unlocked by the Lipidome
2023-09-12
The sequencing of the human genome promised a revolution in medicine, but scientists soon realized that a genetic blueprint alone does not show the body in action. The lipidome may be filling out more details of human physiology that are not fully seen in the human genome. A new study from the lab of Michael Snyder, PhD, the Stanford W. Ascherman, MD, FACS professor in genetics, is among the first to deeply dive into the human lipidome and track how it changes under healthy and diseased ...
