Air filtration at home and work is an easy health win.
In my house and office, each room has an air filter and monitor. I try to maintain pristine air quality 24/7.
Air pollutants PM2.5, PM10 and poisonous gases like volatile organic compounds (VOCs), nitrogen oxides, carbon monoxide, and sulfur dioxide, directly contact the respiratory tract, lungs, and eyes, causing irritation and direct toxicity.
Smaller particles, particularly ultrafine particles and certain PM2.5 components, can cross the lung tissue (alveoli) into the bloodstream, leading to systemic and metabolic toxicity, as well as hormone and immune dysregulation. Airborne pollutants can also be ingested, irritating the digestive system.
Air pollutants increase the risk of respiratory diseases, including lung cancer, negatively affect children's development, focus, and cognitive performance, and are increasingly linked to metabolic disruption, liver disease risk, allergies in children, and elevated risks of multimorbidity and mortality.
Using an in-room HEPA filter is a good idea, even if your home uses an HVAC system with filtration. This is because many pollutants originate indoors; cooking, especially pan frying, is a major source of DNA-damaging and potentially carcinogenic toxins, such as aldehydes and PAHs.
Key strategies for preventing internal air pollution buildup are good kitchen ventilation with an effective kitchen hood and excellent overall air circulation.
Without proper ventilation, frying can temporarily make your kitchen air quality worse than the most polluted areas globally.
Additionally, if you use an HVAC system, ensure filters are replaced regularly, and the system is inspected for humidity and mold, as these can contribute to mold and moisture problems in the home. The same regular filter replacement applies to your kitchen hood and in-room air filters.
The video below demonstrates the significant difference achievable even with simple, small in-room HEPA filters. These units start at approximately $50 (with filter changes every 2–3 months costing around $20) and can dramatically improve your indoor air quality.

Love this future
Jared Isaacman@rookisaacman
Thank you, Mr. President @POTUS, for this opportunity. It will be an honor to serve my country under your leadership. I am also very grateful to @SecDuffy, who skillfully oversees @NASA alongside his many other responsibilities. The support from the space-loving community has been overwhelming. I am not sure how I earned the trust of so many, but I will do everything I can to live up to those expectations. To the innovators building the orbital economy, to the scientists pursuing breakthrough discoveries and to dreamers across the world eager for a return to the Moon and the grand journey beyond--these are the most exciting times since the dawn of the space age-- and I truly believe the future we have all been waiting for will soon become reality. And to the best and brightest at NASA, and to all the commercial and international partners, we have an extraordinary responsibility--but the clock is running. The journey is never easy, but it is time to inspire the world once again to achieve the near-impossible--to undertake and accomplish big, bold endeavors in space...and when we do, we will make life better here at home and challenge the next generation to go even further. NASA will never be a caretaker of history--but will forever make history. Godspeed, President Donald J. Trump, and Godspeed NASA, as America leads the greatest adventure in human history 🇺🇸

Self-driving in the Loop!
TesAli@Ali_Farhat6
I rode in the new self driving Tesla in the Las Vegas Loop! It was WAY smoother than a human driving in the Loop. Zero human input. It wasn’t busy so he let us ride back as well. Driver said they soon will be giving rides all the way to the airport. We are in the future.

Elon, please stop joking about murder. Everything else, I don’t mind what crazy thing you say, but this isn’t something to play around with. You’ve built products and companies that are changing the world, and the reality is there are people and companies out there who don’t like that and see you as a real threat. Your life is too important, not just for Tesla and SpaceX, but for humanity as a whole. Please maximize your security and take every precaution possible. The people who care about you don’t want to see you become a headline - we want to see you keep building the future. @elonmusk

Grok Imagine prompt, also by Grok:
Create a meme featuring a cute cat sitting on a keyboard, staring intently at a computer screen displaying a cartoon mouse cursor. The cat has a focused, almost serious expression. Text at the top in bold Impact font, white with black outline: ‘Why was the cat on the computer?’ Text at the bottom: ‘To keep an eye on the mouse!’ Use a cozy, home-office background with a warm, humorous vibe.

Options to get to dinner tonight:
Walk: Free
Bus: $3 per person
Robotaxi: $3.82
UberX: $9.93
Lyft Standard: $10.85
Waymo: $21.54 ($11.54 w/ $10 off referral)
Low cost per mile will be disruptive. People will own cars way less if autonomy makes it this cheap to get around.

First autonomous vehicle delivery!
Elon Musk@elonmusk
There were no people in the car at all and no remote operators in control at any point. FULLY autonomous! To the best of our knowledge, this is the first fully autonomous drive with no people in the car or remotely operating the car on a public highway.
