Not only is this fascinating, but THIS is the best form of social media. No political valence, no poser influencer bullshit, just interesting content. But seriously, read the thread…it is really interesting. Another profound gender difference worth understanding better.

You have your mother's cells in your brain right now. If she ever carried you, yours are in hers. Scientists looked at the brains of 59 women after they died, ages 32 to 101. In 63% of them, they found their sons' DNA scattered across different brain regions. The cells had traveled from the womb, through the blood, past the wall that normally keeps foreign material out of the brain, and settled in. The oldest woman still carrying her son's cells in her brain was 94. In mice, those cells became functional brain cells. The transfer starts as early as 7 weeks into pregnancy. Your cells slip through the placenta into your mother's body. Hers slips into yours. One study found a mother still had her son's cells in her blood 27 years after giving birth. After delivery, between 50 and 75% of women carry their child's cells. During pregnancy, up to 6% of a woman's blood DNA comes from the baby. When a mother's heart gets damaged during or after pregnancy, the baby's cells travel to the injury, latch on, and turn into beating heart cells, blood vessel lining, and muscle. Heart failure tied to pregnancy has a 50% spontaneous recovery rate, better than every other kind. The Mount Sinai team behind the research thinks the baby's cells are fixing the mother's heart from the inside. The cancer data caught me off guard. A study compared healthy women to women with breast cancer. 85% of the healthy group still carried their children's cells. Only 64% of the breast cancer group did. That works out to about 4x lower odds of getting breast cancer if you kept those cells. The working theory is that they patrol the body and catch cancer cells before they grow. A 2022 study found that in developing mouse brains, a mother's cells controlled the brain's immune cells, preventing them from cutting too many connections between brain cells. Your mom's cells helped wire your brain before you were born. And it stacks across generations. A woman can carry cells from her kids, from her own mother, and even from pregnancies her mother had before her. Three generations of cells from different people, living inside one body.

There is so much wrong with this. First, accountability starts at the top. Making excuses for Trump lays bare how much this is a cult of personality. But in defense of some of these people she is trying to blame, toppling the regime could be a good idea with poor execution.
RedWave Press@RedWavePress

Megyn Kelly on the Iran War: “As this thing goes south, we need to know exactly who talked [President Trump] into it and what representations were made to convince the president that this was a good idea. Who? Who specifically? The names we know are Bibi Netanyahu first and foremost. Lindsey Graham, equally to blame. We know from the Wall Street Journal report that Mark Thiessen of Fox News and General Jack Keane were major advocates of the war. Ok, I like those guys, but they appear to have been very wrong that this was a good idea.” “And we could keep going. Mark Levin, chief among them. He says now, ‘Oh, it wasn’t me.’ Every night, every night on Fox News out there urging the president to do this. And then he had a meeting with him in June, where we know, he denies it now, we know he pushed him for this.” “Ben Shapiro was out on his show every day pushing this war. Like, there were very prominent activists on the right who were practically frothing at the mouth for this thing. And now that it’s not only going poorly, but the president’s poll numbers are in a precipitous freefall, we’d love to see some accountability. Who? Who promised him what?”

@RobertCrisan59 @ElissaSlotkin I live in Michigan…what is it you think the problem is here. Don’t tell me about some other state, that’s there problem to fix. My question is what does Michigan need to do and why?

@RobertCrisan59 @ElissaSlotkin First, this passport/birth certificate stuff is an objectively bad idea. The lack of an alternative doesn’t change that. Now if you want to talk policy, we need to clearly articulate and substantiate the problem before we can even argue about the merits of a policy.

I have a theory: what works in the middle of the country will work on the coasts, but not in reverse. That’s why we need to hear from people in places like Michigan, Idaho, and Kansas City. Because I’m in the business of winning elections. And we’re all seeing what happens when Democrats lose focus on the middle class.

Mike Levin
Mike Levin@MikeLevin·
I’ve been in Congress through divided governments, bitter fights, and historic crises. I’ve never seen anything like the last 24 hours. Republican House Speaker Mike Johnson killed Republican Senate Majority Leader John Thune’s bipartisan deal to fund the TSA, Coast Guard, and FEMA.  It was a deal that had the support of Senate Republicans and Democrats alike, 100-0! Why? Because Johnson places his own political survival and fealty to Trump over all else, including long waits at airports or anything else. We could have passed it in the House easily if only Johnson had allowed the vote to proceed. But instead he blew up the whole thing. Where this goes next is anyone’s guess, but what’s very clear is that Johnson is the worst and most subservient speaker in modern American history.

@RobertCrisan59 @ElissaSlotkin To be clear, only US citizens are allowed to vote now. You don’t need more laws. Have you read this law? Do you have your passport or birth certificate handy? I’m in favor of voter ID, but this legislation would be a major pain if passed.

I really hope this proves correct. But I fully expect to see new AI models that are basically engineered to tell you what you want to hear. But I do commend the current generation for their seemingly disciplined and objective training.
Stefan Schubert@StefanFSchubert

While social media is polarising, evidence suggests AI may nudge people towards the centre. This holds true of all studied models. Grok is more right-leaning than other models, but also has depolarising effects. By @jburnmurdoch.

Lines at TSA aren’t the only budgetary issue travelers should be worried about. People should be terrified by this. All the effort to design planes to be extremely safe gets unraveled if you don’t have well trained and staffed controllers!

Taylor: The day that I decided to quit that administration was the day when a mentor of mine from capitol hill had died. His name was John McCain. The flags were at half staff around the country, and the president was trying to call us in Australia on the other side of the world, to say, not put out a statement in honor of John McCain, but to say, raise the flags back up. I don't care if you agreed with John McCain or disagreed. It didn't matter like Bob Mueller, he served this country in uniform. He was a sitting united States senator. He deserved to be honored with the flags at half staff—for the president of the United States to be so petty, so small and petty, to tell us to raise the flags back up in an act of active dishonor, tells you everything you need to know about that man and his lack of integrity and character.

GOP Senator Kennedy admits Trump is the reason for TSA shutdown: "He said said 'No deals with the Democrats.' We could have had TSA paid by the end of the week. But the President said 'No deal.'"

After blocking it 7 times, Senate Republicans agree that we should fund TSA, FEMA and Coast Guard, and set ICE aside while we negotiate reforms. President Trump is holding DHS funding hostage to protect ICE. We can pass this funding bill today. thehill.com/homenews/senat…

All these people yammering about the “deep state” need to understand the importance of competent government. And yes, you need to pay taxes if you want robust infrastructure and services. This stuff doesn’t just automatically happen. Selfless civil servants have to toil over it.
Aakash Gupta@aakashgupta

The air traffic controller cleared the fire truck onto the runway. Seconds later, the same controller screamed “stop, stop, stop.” The plane was doing 93 to 105 mph. Both pilots are dead. Everyone will frame this as controller error. One controller was simultaneously managing a United flight that aborted takeoff after an anti-ice warning, dispatching a fire truck across an active runway, and sequencing an inbound Air Canada landing at highway speed. At 11:40 PM. On a mandatory overtime shift at a facility that has been understaffed for years. A system that assigns one person that workload will produce exactly this outcome. The only variable is when. The FAA is short approximately 3,000 controllers. The headcount dropped 13% from 2010 to 2024 while flight volume rose 10%. Over 40% of the FAA’s 290 terminal facilities are understaffed. The New York TRACON, which manages the most congested airspace in America across LaGuardia, JFK, and Newark, has been chronically below target. Newark was operating at 59% of its staffing goal. LaGuardia handles 900 flights a day. The hiring pipeline is broken at every stage. Only 2% of applicants complete the full process. Training takes up to 6 years. The FAA Academy in Oklahoma City is a bottleneck, with roughly 35% of trainees washing out. Congress blocked legislation to build a second academy. In one recent hiring cycle, the FAA brought on 1,512 candidates and lost 1,300 in the same window. Net gain: around 160 controllers for an entire country. Three things need to happen and everyone who can make them happen has known for years. Congress needs to fund and authorize a second FAA training academy. One facility in Oklahoma City cannot produce enough controllers for 900 million annual passengers. Members of Congress from Oklahoma have actively blocked this. That needs to end yesterday. The FAA needs to cut certification time. Six years from application to fully certified controller is absurd. The agency’s own data shows tower simulators reduce certification time by 27%. They’ve installed them at 95 facilities. That should be every facility, and the simulated hours should count toward more of the certification requirement. The FAA needs to stop plugging staffing gaps with mandatory overtime. Controllers at understaffed facilities are working six-day weeks rotating between morning, mid, and night shifts. The NTSB has flagged fatigue repeatedly. The controller last night was managing overlapping emergencies during a nighttime operation. Overtime is not a staffing plan. It’s a countdown to the next runway collision. The controller said “I messed up” to a Frontier pilot who watched the whole thing. The pilot responded “No man, you did the best you could.” One of them is right. The answer determines whether this happens again.

God help us. This is disgraceful language coming from a Christian, or anyone with a soul. It was just as wrong to celebrate the death of Charlie Kirk as it is to celebrate that of Robert Mueller. May they rest in peace. And may we never forget that Jesus's message is about mercy.

The alleged victim in this case, Kenneth Herring, blew through a red light and slammed into a semi-trailer, hard enough to make it tilt. An off-duty officer who approached him noticed that he seemed impaired. /1

An absolutely excruciating moment at the Georgia Supreme Court this week. Justice Peterson pressed state attorney Deborah Leslie over her citations to cases that apparently don’t exist.
