New method helps pocket-sized DNA sequencer achieve near-perfect accuracy

Posted by in categories: biotech/medical, engineering

Researchers have found a simple way to eliminate almost all sequencing errors produced by a widely used portable DNA sequencer, potentially enabling scientists working outside the lab to study and track microorganisms like the SARS-CoV-2 virus more efficiently.

Using special molecular tags, the team was able to reduce the five-to-15 percent error rate of Oxford Nanopore Technologies’ MinION device to less than 0.005 percent—even when sequencing many long stretches of DNA at a time.

“The MinION has revolutionized the field of genomics by freeing DNA sequencing from the confines of large laboratories,” says Ryan Ziels, an assistant professor of civil engineering at the University of British Columbia and the co-lead author of the study, which was published this week in Nature Methods. “But until now, researchers haven’t been able to rely on the device in many settings because of its fairly high out-of-the-box error rate.”

DNA in water used to uncover genes of invasive fish

Posted by in categories: biotech/medical, food

Invasive round goby fish have impacted fisheries in the Great Lakes and the Finger Lakes by competing with native species and eating the eggs of some species of game fish.

But the camouflaged bottom dwellers can be difficult to find and collect—especially when they first enter a new body of water and their numbers are low and they might be easier to remove.

In a proof-of-principle study, Cornell researchers describe a new technique in which they analyzed environmental DNA—or eDNA—from in Cayuga Lake to gather nuanced information about the presence of these invasive fish.

Scientists investigate phages that can kill the world’s leading superbug, Acinetobacter baumannii

Posted by in category: biotech/medical

A major risk of being hospitalised is catching a bacterial infection.

Hospitals, especially areas including intensive care units and surgical wards, are teeming with bacteria, some of which are resistant to —they are infamously known as ‘superbugs’.

Superbug infections are difficult and expensive to treat, and can often lead to dire consequences for the patient.
