Health advocates shocked as Carney Liberals back away from pharmacare program Health advocates say they’re shocked to hear the federal government may not sign more pharmacare funding deals, which would leave coverage uneven across the country.

Insiders say Carney government rejected NDP demands before crucial budget vote The opposition NDP wanted the minority Liberal government to devote roughly $10 billion to affordable housing, pharmacare and other priorities.

In case you need a reminder, here's how the Liberals are behaving now.

Yea, the NDP need *major* change and/or we need a new left party.

But here's question for the "NDP can't win" / "NDP are no better" commenters I get constantly:

Was it better when the Liberals had a minority and the NDP held balance of power, or is it the same now that it's just the Libs and Cons?

Find Members of Parliament - Members of Parliament - House of Commons of Canada Find Members of Parliament - Members of Parliament - House of Commons of Canada

Both Carney and Poilievre backed the strikes. The NDP condemned them. If bipartisan support for bombing countries bothers you as much as it bothers me, contact your MP ourcommons.ca/members and tell them Canada should be a voice for diplomacy, not rubber-stamping unauthorized military action.

This recent RCT of an "AI stethoscope" claims the technology "shows promise" for diagnosing cardiovascular conditions.

It does not.

It is a textbook example of the risks of conducting unprincipled 'per protocol analyses'. Once again, peer review at a major medical journal has failed.

Kansas Sends Letters To Trans People Demanding The Immediate Surrender Of Drivers Licenses "The legislature did not include a grace period."

It seems all Kansas-issued trans drivers' licenses are invalid, effective tomorrow

It is now illegal for trans people to drive a car until they surrender their license at a DMV (that most will need to drive to) and have it reissued with the wrong gender marker

This was never about woman's sports

The boys’ club: How Epstein’s influence shaped the exclusion of women in STEM In one email, an AI researcher suggested it’s β€œhard to be brilliant if you are worrying if you look fat or why another woman hates you.”

"But he didn't know" okay, great, but did he speak out against an overtly sexist, racist power broker, or did he accept the invitations and the money? Because this culture doesn't just happen. It's created by the consent of the people who have access to those spaces.

I know OpenAI's CEO is one of (the?) largest Trump donors. Beyond "GenAI is evil," which, you do not need to convince me, I am looking for *specifics* here: what are the ethical ramifications of giving your money to Anthropic that academics should think about when using Claude Code?

The fundamental premise behind AI-enabled cheating is that coursework is merely busy work, because your'e just doing it for professors.

We would never say that showing up for football practice is merely busy work because you're just doing it for your coaches.

Men's health is important. But have a look at this in context:

1) In combination with other moves (see links below), this looks like another pitch to conservative voter bros.

2) It's framed in terms of -- you guessed it -- economic productivity.

In terms of what cures are being lost:

- Epstein-Barr virus is perhaps the major trigger for multiple sclerosis
- herpes simplex virus causes cold sores, genital herpes, infections in babies, deadly meningitis
- shingles virus causes an intensely painful disease

With the shuttering of the Walter Reed Biosystematics Unit last year by the US Army we are loosing a lot of expertise and future expertise in insect taxonomy and ecology.

Gladys Mae West obituary: mathematician who pioneered GPS technology She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

"Despite her groundbreaking work, West was long left out of histories that discussed the development of GPS."

What a remarkable woman. RIP Gladys Mae West.

7 Reasons Teens Say No to AI Some young people only turn to artificial-intelligence chatbots as a last resort, citing concerns about relationships, creativity, the environment and more.

As these teens describe, AI can diminish human relationships; devalue art; threaten the environment; lead to laziness; give unreliable results; pose privacy concerns; and be misused.

So, please, stop with the narratives of inevitability and let's embrace a pedagogy and politics of refusal.

The biggest challenge Canadians face right now involves the utter disconnect between Carney’s rhetoric and his actual policies. It makes it so difficult to even begin a debate about what actually standing up to the US would look like.
