7 Things to Know about the U.S.’s Capability to Detect Omicron

7 Things to Know about the U.S.’s Capability to Detect Omicron

A visualization of the original coronavirus causing COVID-19, which has now been detected across the globe in a highly mutated form called Omicron.

If the new variant Omicron isn’t here already – which many experts suspect that it is – it will be soon. While we wait for scientists to conduct the necessary research to characterize its transmissibility, potential fitness at immune evasion, and disease severity, we wanted to give Leaps.org readers a window into how the U.S. is positioned to detect the variant. So we spoke to Kelly Wroblewski, director of infectious diseases at the Association of Public Health Laboratories, a membership organization that represents state and local government health labs in the United States. Here are seven insights she shared.

Scientists experiment with burning iron as a fuel source

Sparklers produce a beautiful display of light and heat by burning metal dust, which contains iron. The recent work of Canadian and Dutch researchers suggests we can use iron as a cheap, carbon-free fuel.

Try burning an iron metal ingot and you’ll have to wait a long time — but grind it into a powder and it will readily burst into flames. That’s how sparklers work: metal dust burning in a beautiful display of light and heat. But could we burn iron for more than fun? Could this simple material become a cheap, clean, carbon-free fuel?

In new experiments — conducted on rockets, in microgravity — Canadian and Dutch researchers are looking at ways of boosting the efficiency of burning iron, with a view to turning this abundant material — the fourth most common in the Earth’s crust, about about 5% of its mass — into an alternative energy source.

How to Use Thoughts to Control Computers with Dr. Tom Oxley

Leaps.org talks with Dr. Tom Oxley, founding CEO of Synchron, a company that's taking a unique - and less invasive - approach to "brain-computer interfaces" for patients with ALS and other mobility challenges.

Synchron

Tom Oxley is building what he calls a “natural highway into the brain” that lets people use their minds to control their phones and computers. The device, called the Stentrode, could improve the lives of hundreds of thousands of people living with spinal cord paralysis, ALS and other neurodegenerative diseases.

Leaps.org talked with Dr. Oxley for today’s podcast. A fascinating thing about the Stentrode is that it works very differently from other “brain computer interfaces” you may be familiar with, like Elon Musk’s Neuralink. Some BCIs are implanted by surgeons directly into a person’s brain, but the Stentrode is much less invasive. Dr. Oxley’s company, Synchron, opts for a “natural” approach, using stents in blood vessels to access the brain. This offers some major advantages to the handful of people who’ve already started to use the Stentrode.

The audio improves about 10 minutes into the episode. (There was a minor headset issue early on, but everything is audible throughout.) Dr. Oxley’s work creates game-changing opportunities for patients desperate for new options. His take on where we're headed with BCIs is must listening for anyone who cares about the future of health and technology.
