So this is how MAGA is doing MAHA? I still hear people say ‘it’s only 4 years.’ It isn’t. The effect of releasing noxious chemicals into our environment and everyday products, like that of cancelling medical research, blocking basic public health, and decimating protected national lands and animals, will last for generations, if not forever. This affects everyone, even those with blinders on to the pain of those detained, deported, traumatized, maimed and executed.

Downtown Tokyo is an easy train ride from Haneda Airport. That made it a no brainer after spending the night in terminal 3 between my domestic and international flights. Enjoyed lunch in the fish market, ran errands, walked around, and back to the airport before 2:30pm to check my bags!

As NYer, I’m used to city life. But as a frequent traveler to Japan, I regularly remind myself there are some differences when going out and about here. Here are two basics:
1. In NYC, there’s a trash can on every corner. In Japan, there are almost no public garbage receptacles. After the 1995 Tokyo subway sarin gas attack by the Aum Shinrikyo cult, garbage cans were removed so terrorists couldn’t use them to hide canisters and bombs. In a society that values cleanliness as this one does, tossing garbage on the street is unthinkable and separating garbage/recycling is strict. If you hunt, you can find a few trash/recyclable bins at train stations and airports, but you won’t find them on the street. Easy fix: carry a little bag for trash with you to dispose of when you get back to your hotel/apartment.
2. Jaywalking is so common in NYC (and so rarely enforced), it was decriminalized in early 2025. Not so in Japan. I’ve stood on street corners with nary a car in site, and a crowd of pedestrians patiently waiting on each side for the walk light to change to green. If you’re caught, you can get a police warning or fine. That’s unlikely but the quiet social disapproval is fierce! It’s a constant struggle to curb my automatic response to sprint across streets without even looking at the light - i’m working on it. 👍☺️

We did it! And we want to do it again 😳 - seems crazy, but have a real sense of accomplishment after accepting and completing the challenge. We split all the stations except my two least favorite - lucked out that my friend loves burpee broad jumps and wall balls 👍 She’s also a long distance runner - unfortunately rule is we both have to do all those laps. She was my ‘coach’/‘cheering squad’ as we rounded into each lap - I slowed down but kept running. Next challenge: improve my running endurance, and build my burpee/wall balls skills! Who knows? Next time we might even get close to 1hr 30min 😉

Do not get distracted by politics or spin. This is not about hunting republicans, democrats, the wealthy, powerful or influential. This is not about consensual s*x between adults. The Epstein files are evidence in a criminal case against adult pedophiles, rapists, and those complicit with them, in the s*xual abuse of children. Be disgusted. Get mad. Follow the law. Prosecute these vile perpetrators of child abuse.

The truth will out.

Our country gone mad, but science remains science. I’m now following cool science pages because I need beautiful reality checks for my mental health. Enjoy!

repost In microgravity, squeezing a wet towel doesn’t behave the way you expect.

The water doesn’t drip or fall away like it does on Earth. Instead, it clings to the towel and the astronaut’s hands, forming a floating, jelly-like mass held together by surface tension.

Canadian astronaut Chris Hadfield famously demonstrated this effect aboard the International Space Station, showing how even simple everyday actions change completely in weightlessness.

🤦‍♀️🤬 Trump is obsessed with self aggrandizement. If there is something he wants - like natural resources from another country - he expects to get it however illogical, illegal, dangerous for the US and the world. And he’s an infantile bully who will punish anyone who stands in his way. Needless to say, we already know that tariff’s hurt Americans who are already strapped in Trump’s America.

repost President Donald Trump said Saturday the US will impose new tariffs on several European countries unless a deal is reached for the purchase of Greenland, escalating his long-running push for US control of the Arctic territory.

Important warning in this excellent post by
repost: If you’ve ever wondered how closely medspas are actually regulated, new reporting out of New York City offers an important reality check.

A New York City Council Oversight and Investigations Division report released in December 2025 detailed the results of inspections conducted between June and September 2024 at 15 medspas across all five boroughs. Every single location inspected was found to be out of compliance with state laws governing medical procedures.

Key findings from the report included:

- All inspected medspas were offering medical procedures without proper licensure
- 93% failed to properly display required licenses
- 73% operated without a medical professional present
- 86% lacked required safety records
- Over half had sanitation or hygiene violations, along with chemical or fire safety concerns
- Several cases have already resulted in license revocations

Following the release of this report, the American Academy of Dermatology Association and the New York State Society of Dermatology and Dermatologic Surgery issued a joint statement urging New York State lawmakers to strengthen medspa oversight. Their recommendations focus on clearer disclosure for consumers, stronger enforcement, and public education so patients understand which procedures non-physician facilities are legally prohibited from performing.

As a board-certified dermatologist, these findings highlight why medical procedures, even when considered “cosmetic,” require proper training, licensure, and on-site physician oversight. Treatments involving injections, lasers, or energy-based devices are safest when performed in a medical setting by or under the direct supervision of a licensed physician.

As medspas continue to grow in popularity, transparency and patient education are critical. Knowing who is performing your treatment, and under what medical supervision, matters.

because science/nature are cool and much more soothing to think about than the decline of american democracy by the far right and the increase in antisemitism by the far right and far left. So please enjoy watching and read explanation below! ❄️🫧

Watching a bubble freeze is like witnessing a tiny planet undergo a “phase transition” in real-time. This stunning phenomenon occurs through a process called the Mpemba effect combined with Marangoni convection. When a soap bubble hits sub-zero temperatures, the thin layer of water between the soap molecules begins to crystallize. Because the liquid film is so thin, the freezing happens at multiple points simultaneously, creating “ice flakes” that swirl around the surface like miniature tectonic plates.

The crystal growth is driven by latent heat of fusion. As the water freezes, it releases a tiny amount of heat, which creates tiny currents in the remaining liquid. This keeps the ice crystals moving in a beautiful, spinning dance until the entire structure locks into a solid, translucent sphere. Unlike a normal bubble that pops into droplets, a frozen bubble—often called an “ice globe”—will eventually shatter like fine glass or deflate slowly as the air inside cools and contracts, leaving behind a delicate, shriveled husk of silk-like ice.
