Fantastic photos!!

Carpenter bee in a hosta flower in the afternoon sun in Michigan.

We have a couple of carpenter bees who moved into our fence this spring and I've been trying to catch a photo, but they are very busy! I finally got one I liked today.

Great photo! Love the light

💯 this would be amazing

The mystery rise of lung cancer in non-smokers The number of lung cancer cases in people who have never smoked is increasing. The disease is different from lung cancer caused by smoking, so what causes it?

Interesting article that discusses rising cases of lung cancer in non smokers.

Air pollution is an important factor and how it causes the cancer may be different compared to cigarette smoke.

No way!! That’s the largest crowd I’ve ever seen in Ann Arbor

A message from the AAAR Executive Committee We are writing this note of support and encouragement for everyone in the AAAR community and especially our colleagues at federal laboratories and in federal agencies, including program managers and staff that support aerosol science and, more broadly, scientific research across the country. We look forward to supporting our federal partners in any way we can, starting with travel grants for recent/current federal scientists and program managers for participation in the upcoming 43rd AAAR conference in Buffalo, NY. The call for travel grants will be made around June 1st. We also want to share with everyone that a revamped job board will be active in early Fall. For our federal colleagues: your work and your contributions to our community and the scientific research enterprise are extremely valuable and greatly appreciated. We are very thankful for all of the opportunities we have had to collaborate with you, learn from you, and engage in discussions with you at conferences. We deeply value your contributions to aerosol science and the many scientific fields with which we overlap. AAAR and its members have benefited tremendously over its 43 years of existence because of the direct contribution of federal researchers to our field. Some of the most impactful publications in our Aerosol Science & Technology journal have come from projects led by federal scientists, including from large-scale field campaigns that were only possible because of you. Finally, we really appreciate your ongoing leadership and support of the AAAR community through involvement in committees, working groups, and the Board of Directors. We want to express our strong support for federal scientists in and beyond the AAAR community, and we look forward to your continuing involvement in AAAR and the field of aerosol science.

AAAR has new travel grants for current/recent federal scientists and program managers and an updated job board coming soon. See below for a statement from the AAAR Executive Committee:

This is my favorite one!

I really like the figures (figure 3 especially) and the acknowledgments 😹

This is fantastic. And an impressive amount of work!

Trump needs to understand that Harvard has 400 years of experience ignoring the demands of people who will be gone in four years.

Happy to share a recent publication! This work was carried out by two undergrads in my group at William and Mary: Hongmin Yu (now at Caltech) and Natalie Warren (now at Brown). I'm especially proud of their detailed work on a complicated set of samples. 1/5

...and many more! Please feel free to add more names of awesome women in science and engineering.

Happy #InternationalWomensDay 2025 to everyone. Thank you to all the women who inspire and motivate. There are more than I can list, and only a small fraction on Bluesky, so I will list a few and highlight that there are so many in atmospheric chemistry, climate science, and indoor chemistry.

If the words didn't matter, they wouldn't be trying to stop us writing them.

If the pictures didn't matter, they wouldn't be taking them down.

If the ideas didn't matter, they wouldn't be trying to stop funding.

All of this matters for who we are and we should not remove things in anticipation.

The NSF is the US engine of basic science discovery and technology innovation. This decision is a gift to our overseas competitors.

I'm very glad this is still running. The removal of scientific data that we have already paid for via our taxes is theft and it needs to be corrected!

hello all - has anyone heard anything about NSF postdocs or GRFPs getting their February stipends today? 🧪

Put a scroll in it! 😁

You did great, the video was awesome and I can't wait for the construction streams!

Would love to hear reviews of the rest. Looking forward to the discussion this week!

Did Jon finish playing/reviewing those or drop off part way?

Kitty in a nice tuck on a chair. Cats have such funny sleeping positions!

Cats are the best! He's either sleeping or doing some very focused training for an Olympic diving competition!

LIARS!

So peaceful, I love it!

I'm having a great time at #AGU24! Very happy about my group's first poster session presentations. #UM_CEE

Only five posts here and this kinda nails it!

Hi Brightpaw, you look especially radiant here! 🌅 Looking forward to your feed here, Perc! You have the best outfits and garden photos 🙂
