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.

ABC News: German authorities accuse Australian man of running DarkMarket, the world’s largest illegal online marketplace.


An Australian is allegedly at the centre of what German authorities believe was the biggest illegal marketplace on the darknet where more than $220 million was transacted over sales of drugs, forged money, SIM cards and bogus credit cards.

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.

That means quantum computers can explore many possibilities simultaneously, while a classical computer would have to run through each option one after the other. Progress so far has seen quantum computers perform calculations much faster than traditional ones, but their ultimate test would be when they can do things that classical computers simply can’t. And that milestone has been dubbed “quantum supremacy.”

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.
