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.

Chinese quantum computer completes 2.5-billion-year task in minutes

Posted by in categories: quantum physics, supercomputing

Circa 2020 o.o


Researchers in China claim to have achieved quantum supremacy, the point where a quantum computer completes a task that would be virtually impossible for a classical computer to perform. The device, named Jiuzhang, reportedly conducted a calculation in 200 seconds that would take a regular supercomputer a staggering 2.5 billion years to complete.

Traditional computers process data as binary bits – either a zero or a one. Quantum computers, on the other hand, have a distinct advantage in that their bits can also be both a one and a zero at the same time. That raises the potential processing power exponentially, as two quantum bits (qubits) can be in four possible states, three qubits can be in eight states, and so on.

GM shares hit record high as automaker reveals electric van and delves into flying cars

Posted by in categories: robotics/AI, sustainability, transportation

The potential foray into “personal air mobility” was announced as part of Cadillac’s portfolio of luxury and EV vehicles. It included an autonomous shuttle and an electric vertical takeoff and landing (eVTOL) aircraft, or more commonly known as a flying car or air taxi.

Michael Simcoe, vice president of GM global design, said each concept reflected “the needs and wants of the passengers at a particular moment in time and GM’s vision of the future of transportation.”

“This is a special moment for General Motors as we reimagine the future of personal transportation for the next five years and beyond,” Simcoe said.
