New Internet Speed World Record: 178 Terabits a Second

 Big numbers go over our heads. So here's some perspective:

"the research team led by Dr. Lidia Galdino (UCL Electronic & Electrical Engineering), achieved a data transmission rate of 178 terabits a second (178,000,000 megabits a second) – a speed at which it would be possible to download the entire Netflix library in less than a second."

Physicists: Wormholes Large Enough to Travel Through Are Possible

 Intriguing but not what we'd hoped for: "These theoretical wormholes would blink travelers 10,000 lightyears away in a single second, though thanks to the quirks of special relativity an observer from Earth would see the journey take 10,000 years":

Why We Believe Planting 1 Trillion Trees Can Save the Planet

Worth keeping in mind: "This effort could capture an estimated 200 gigatonnes of carbon over the coming decades, an amount equal to two-thirds of the pollution produced since the Industrial Revolution. But it will take time for young trees to capture the same amount of CO2 as mature forests."

Chernobyl fungus could shield astronauts from cosmic radiation

"Extrapolating these results, the researchers estimated that a roughly 8-inch layer of C. sphaerospermum "could largely negate the annual dose-equivalent of the radiation environment on the surface of Mars." That would be a significant benefit to astronauts. After all, an astronaut who is one year into a Mars mission would have been exposed to roughly 66 times more radiation than the average person on Earth."

Learning of Foreign Language Sounds Boosted by Non-invasive Nerve Stimulation

"By the end of the training, those participants were 13% better on average at classifying tones and reached peak performance twice as quickly as control participants who wore the tVNS device but never received stimulation."

"When they launch, they’ll already be five times faster than our fastest computer"

"Quantum computers could potentially reduce the time it takes to run these simulations from billions of years to a few minutes."
