Asian giant hornets, called by some researchers as "murder hornets," have arrived in the U.S., the New York Times reports.

Why it matters: The insects, which were spotted by a beekeeper in Washington state in December, kill roughly 50 people a year in Japan — and scientists are worried they "could decimate bee populations" in the U.S., the Times reports.

What they're saying: “This is our window to keep it from establishing,” Chris Looney, an entomologist at the Washington State Department of Agriculture, told the Times. “If we can’t do it in the next couple of years, it probably can’t be done.”

Increasingly, though, they want to add their own rules — the internet with an asterisk, if you will. The question is just how many local rules you can make before the network's universality disappears.

Left-wing climate activists don't want Joe Biden getting advice from people with credentials they don't like — and they're increasingly going public with their campaign.

Why it matters: Nobody is confusing Biden with President Trump, and his climate platform goes much further than anything contemplated in the Obama years.
