Since July, the Marine Mammal Center in Sausolito, California has seen 68 sea lions sickened by toxic algae come through it's doors—just two less than they saw in all of 2016. The sea lions show signs of domoic acid poisoning, a toxin that is produced by the algae Pseudo-nitzchia. The toxin builds up in the sea lions, which eat fish that consume the algae. In many cases, domoic acid poisoning is fatal.

The strandings started farther south several months ago, Justin Viezbicke, the NOAA stranding coordinator for California tells Axios, and have been moving steadily north.

Why it matters: Toxic algal blooms don't just pose a threat to sea life. If humans ingest animals that contain the toxin, they can also die. The Oregon and Washington razor clam fisheries are currently closed due to high levels of domoic acid. Past algal blooms have closed fisheries for entire seasons, losing millions of dollars in revenue.

A new normal?

A record-breaking red tide in 2015 closed fisheries for months

and poisoned animals along the West Coast. At the time, scientists said the event—the largest bloom of Pseudo-nitzchia ever recorded—was likely

linked to climate change

and that similar blooms could become common in the future.

The silver linings of online school

Online learning can be frustrating for students, teachers and parents, but some methods are working.

The big picture: Just as companies are using this era of telework to try new things, some principals, teachers and education startups are treating remote learning as a period of experimentation, too.

Sen. Elizabeth Warren and Hillary Clinton both are slated to speak on the Wednesday of the Democratic convention — Aug. 19 — four sources familiar with the planning told Axios.

Why it matters: That's the same night Joe Biden's running mate (to be revealed next week) will address the nation. Clinton and Warren represent two of the most influential wise-women of Democratic politics with the potential to turn out millions of establishment and progressive voters in November.
