🧠 Alzheimer’s reversed in mice

A new study found that injecting nanoparticles can 'remind' the blood–brain barrier to function properly again, restoring normal brain activity in mice. Human trials could follow within years.

A great read, Femi. Makes me think about how effective the "weird" discourse was before the Harris camp shut it down in the name of decorum.

Field work in Bamfield, a lecture with Tom Reimchen, this is hitting me right in the ca. 2010 nostalgia - how time flies - BMSC is beautiful as ever

I am mostly a marine biologist, but I do happen to be a published spider eye guy too 👁️. Their colour vision is FASCINATING! Here's the receipt: www.sciencedirect.com/science/arti...

In the cacophony of crap news, I recalled seeing this lil' bug. A good reminder that nature is beautiful. Here's a female Sylvan jumping spider, clearly dazzled (or maybe pissed off) at the spider-like eyes of my iphone cameras. Pick an issue, get involved, AND pay attention to the beauty all around

Janthina! The violet colour is so striking in person. They also have counter shading on their shell presumably for camouflage - here's a couple from my camera roll from O'ahu, Hawai'i. I appreciate the neuston love lately there is so much hidden on the surface 👀

It was a day for ballot initiatives in the D.C. Council, as an attempt to repeal Initiative 82 was defeated (but could come back) while lawmakers funded ranked-choice voting, which was approved by voters last year as Initiative 83. For @51st.news: 51st.news/d-c-council-...

D.C. Council approves ranked-choice voting, rejects rollback of tipped wage law (for now)

There was plenty of action on two of D.C.'s ballot initiatives.

Just called the at-large council members of DC to urge them to fully implement initiative-82, the phase-out of a tipped minimum wage supported by almost 80% of DC voters! As a treat, here is a pair of ship wrecks: a By-the-wind sailor run aground next to the Wreck of the Peter Iredale, Astoria, OR

Philly’s AFSCME DC 33 is officially ON STRIKE!

Over 9,000 blue collar city workers who run our streets, libraries, sanitation, and more have refused the city’s lowball offers. They make an average of $46K while our mayor enriches herself, her cronies, and the cops www.inquirer.com/politics/phi...

Thousands of Philadelphia city workers are officially on strike

More than 9,000 city employees are on strike after contract talks fell apart between AFSCME District Council 33 and Mayor Parker’s administration, the first major city worker strike since 1986.

Remora House DC 🎃 @remorahousedc.bsky.social · Jun 25

Remember when Mayor Bowser proposed:

No new funding for permanent housing for individuals experiencing homelessness

Massive cuts to emergency rental assistance

Cuts to street outreach

Cuts to basically all social supports

Just some thoughts while we’re talking about mayors!

When Republican voters surprise pundits, there's always a spate of opinion pieces arguing that we must take the time to understand the wants and desires of said voters. Apparently, when Democratic voters do it, the response is to say they're unserious people who need to grow up. Interesting.

Exclusive: I have confirmed that the federal government is still refusing to process permit applications for land-based wind projects almost six months into the Trump administration. Not just offshore.

It threatens untold billions of capital investments in the United States.

Quinnipiac national poll: Trump's approval rating is 38/53. GOP's approval rating is 32/61. But they have one thing going for them — Democrats are even more unpopular. Dems' approval rating is 21/70.

The congressional Democratic Party is under water with Democratic voters.
