Prokaryotic representative genomes update–over 900 new species!
We are happy to announce an updated bacterial and archaeal representative genome collection! We have selected 13,835 among 214,000 prokaryotic RefSeq assemblies to represent their respective species. The collection has increased by 6% since December 2020. About 950 species are represented for the first time, 476 species are represented by a better assembly, and 170 …
Finding Better Ways to Image the Retina
Every day, all around the world, eye care professionals are busy performing dilated eye exams. By looking through a patient's widened pupil, they can view the retina—the postage stamp-sized tissue lining the back of the inner eye—and look for irregularities that may signal the development of vision loss.
Assemble and annotate your prokaryotic genomes with RAPT
Do you need an easy way to analyze a bacterium you just isolated? The Read assembly and Annotation Pipeline Tool (RAPT) is a pilot service for the assembly and gene annotation of public or private Illumina genomic reads sequenced from bacterial or archaeal isolates. We’ll be giving a webinar on webRAPT on May 19, but …

Confused By CDC's Latest Mask Guidance? Here's What We've Learned
The Centers for Disease Control and Prevention shifted its stance this week on the need to wear masks if you're vaccinated. What's that mean for kids? For travel? For work? Experts weigh in.
COVID-19’s Origins Need Further Investigation, Say Scientists
A letter signed by 18 researchers argues that hypotheses about zoonotic spillover or accidental lab release both "remain viable" in the absence of additional evidence.
