[ad_1] Reviewed by Emily Henderson, B.Sc.November 11, 2020 A large international consortium led by scientists from Uppsala University and the Broad Institute of MIT and Harvard sequenced the genome of 130 mammals and analyzed the data along with 110 existing genomes to allow scientists to identify which locations are important …

[ad_1] A study conducted at the United States Army Research Institute of Infectious Diseases shows how a relatively simple full-length DNA vaccine against the spike glycoprotein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can elicit a neutralizing antibody response in a animal model – even after a single shot …

[ad_1] According to a University of Michigan study, a high-sugar diet reprograms the taste cells in fruit flies, blunting their sensitivity to sugar and leaving a “molecular memory” on their tongues. By examining fruit flies, researchers Monica Dus, Anoumid Vaziri and collaborators found that high-sugar diets completely remodeled the taste …

[ad_1] The fast, low-cost technique is the first to analyze DNA left in animal feces to map complex networks of species interactions in a terrestrial system. It could help redefine conservation as we know it, identify otherwise hard-to-find species, and lead a global effort to restore large areas. Watch the …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 9, 2020 Many environmental and lifestyle factors have been implicated in the decline in sperm quality, and diet is one of the most plausible factors identified in recent years. Additionally, several studies have reported a close association between the alteration of specific sperm DNA …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 9, 2020 At high concentrations, reactive oxygen species – known as oxidants – are harmful to the cells of all organisms and have been linked to aging. But a study from Chalmers University of Technology, Sweden, has now shown that low levels of oxidizing …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 6, 2020 Researchers from the universities of Melbourne, York, Warwick and Oxford have shed light on how encapsulated viruses such as hepatitis B, dengue and SARS-CoV-2 hijack the production and distribution pathways of proteins in the cell – they have also identified a potential …

[ad_1] In a recent medRxiv * preprint manuscript, researchers from Singapore and the United States report the development of a digital CRISPR method for the sensitive, specific and rapid detection of viral nucleic acids at constant temperature, which could be exploited for the detection of severe acute respiratory syndrome coronavirus …

[ad_1] Reviewed by Emily Henderson, B.Sc.November 5, 2020 During the pandemic, infectious disease experts and frontline health workers demanded a faster, cheaper, and more reliable COVID-19 test. Now, leveraging so-called “lab on a chip” technology and the cutting-edge gene editing technique known as CRISPR, Stanford researchers have created a highly …
