HHS Secretary Kennedy’s testimony to Congress today made clear yet again that he is unfit to lead HHS—and his anti-science policies are putting people in danger. ⬇️🧵 @mikethompson.house.gov laid it bare. WATCH:

Data centers could be raising your utility bills—and putting your health at risk—to keep up with their hunger for power. Data centers are gobbling up entire cities' worth of energy, and too often, they're turning to toxic fossil fuels for power. (🧵⬇️)

🔋🚗 Over a million EVs are already on the road—and counting. That increase will create a demand for more battery materials. Recycling older batteries from retired EVs could meet a good amount of that new demand, and doing so will mean less mining, which is a win for communities and the environment.

An animation project I made for Video Production last semester. We had to make a 30-second CM or trailer with at least one live-action shot and one animated/SFX shot. This was a horror-comedy loosely inspired by my experience taking the public bus home. I wanted to play around with mixed media.

Another day, another article about the “top four” candidates in this race. Interesting how the only woman polling right behind them somehow keeps getting edited out. If you’re tired of politics being treated like a private boys’ club, help us prove them wrong.

"He doesn't know what he's talking about... the problems at the Washington Post were entirely created by him." @karaswisher.bsky.social tells @timmiller.bsky.social that Jeff Bezos is wrong twice: about the media business, and about the idea that cozying up to Trump is the only way to survive it.
