Since its initial release in 2000, the human reference genome has covered only the euchromatic fraction of the genome, leaving important heterochromatic regions unfinished. Addressing the remaining 8% of the genome, the Telomere-to-Telomere (T2T)
Almost immediately after the start of the COVID-19 pandemic in 2020, researchers and wastewater utilities around the world began analyzing untreated wastewater for the SARS-CoV-2 RNA. These efforts were largely based on prior experience analyzing

Obesity has repeatedly been linked to reorganization of the gut microbiome, yet to this point obesity therapeutics have been targeted exclusively toward the human host. Here we show that gut microbe-targeted inhibition of the trimethylamine N-oxide (TMAO)

Nucleic acid analysis is used in many areas of life sciences such as medicine, food safety, and environmental monitoring. Accurate, reliable measurements of nucleic acids are crucial for maximum impact, yet users are often unaware of the global
A protocol for increasing soluble protein expression by fusing the chaperone GroEL apical domain with a gene of interest is described herein. GroEL apical domain, the minichaperone that functions independently of GroES and ATP in protein folding, is cloned
Label-free spectromicroscopy methods offer the capability to examine complex cellular phenomena. Electron and X-ray based spectromicroscopy methods, though powerful, have been hard to implement with hydrated objects due to vacuum incompatibility of the
