In an attempt to clear the winter roads (and make deicing easier on the environment, vehicles, and infrastructure), cities across the U.S. are exploring rock salt alternatives — and beet juice is one of the most promising.

Ice breaker: Adding salt to water can drop its freezing point below 32 degrees Fahrenheit.

That little quirk of chemistry has proven incredibly useful for driving in winter weather — by dumping rock salt on roads when it snows, we can prevent water on them from freezing (or melt ice that’s formed) until temperatures sink below 15 degrees Fahrenheit.

What would happen if a nuclear bomb 100 times the size of the one dropped on Hiroshima hit a city of 4 million people?

If that can’t happen, Spencer said he hopes to see a system that lets you bring a “banned user list” to a new network.

After a few pictures leaked this weekend, we now have a full video walkaround of Tesla’s latest Cybertruck prototype.

As we previously reported, some pictures of the latest Tesla Cybertruck have leaked this weekend. It appears to be from Gigafactory Texas, where the automaker plans to build the electric pickup truck late this year. The pictures gave us a better look at the lack of door handles as well as the new wheels without any aero cover on.

Suppose for the moment that one is a science fiction writer. Suppose further that one desires a universe in which intelligence is fairly common and interstellar travel is possible. Suppose that, for compelling plot reasons, one wants humans to be the first species to develop interstellar flight. What, then, could keep all those other beings confined to their home worlds?

Here are options, presented in order of internal to external.

Elon Musk’s brain chip company Neuralink appears to be gearing up to launch its first-ever human trials, with the firm now looking to recruit a director to run the tests.

According to The Guardian, the entrepreneur, who owns a variety of science-based start-ups, is preparing to take Neuralink’s brain chip research to the next stage by hiring a mission-driven Clinical Trial Director to begin human testing. The company is moving toward potentially finding a way to use the technology to treat people with brain and spinal injuries.

The Bowlin family knew they had a history of malformations in the brain. But they had no idea how far back it went.
