New Study: We report the dysregulation of CD4 T cell responses by Type 2 Diabetes in people with TB. Increased circulating Th17 cell subsets and altered CD4 maturation and differentiation. Potential explanation for high risk for TB in those with T2D

Star trail exposure from the ISS, marked by the thick white path of the Moon, Starlink satellites flashing far right, golden city lights streaking across Earth, and arcing stars.

As we get close to leaving @Space_Station, I find myself wanting to savor every moment and every view. None of us are guaranteed to get to do this again, and every minute spent in space is a special one. I dropped into the Cupola to look out the window and just be in the moment, not taking photos or looking for anything in particular. Well, when this view presented itself, I changed my mind … I had to pick up a camera to share this with all of you. Wow!

Useful to remember that, after adjusting for inflation, the NIH budget has been mostly flat or declining since 2003

Sometimes we see lightning strikes that illuminate an entire city at once. This is Singapore last night, and that was a huge thunderstorm. It’s hard to believe, but these pictures were taken all in the span of 1/40 of a second!

A cosmic cherry on top 🍒

@NASAWebb treated us to a sweet perspective: Herbig-Haro 49/50—a towering swirl from a nearby protostar—is (coincidentally) topped with a multi-hued spiral galaxy. Learn more: https://t.co/qYGbz3BBrT

My 3 favourite things about being a scientist: your full time job is to solve mysteries (how cool is that!), constantly being amazed by how beautiful & surprising the natural world is, getting to work with people who are smarter than you & have skills you only dream of having.

A new photo of the Sombrero galaxy from @NASAWebb reveals finer details of the hat-like formation. It has a smooth inner disk, while its “brim” – the outer ring – is made of intricate lumps. https://t.co/9Hj5pd2TmL

Moonrise over Earth is so inspiring. From orbit, the subtlest change in perspective makes the Moon seem just within reach even though we are only 1/1000th closer. Step outside tonight and check out the full Moon. I’ll sure be watching from @Space_Station!

Check out new story with collaborators at TGEN. CRESTA, a new approach to identifying Mtb antigen specific T cells with high order of magnitude. Happy to have played a role.

Keep an eye out this Halloween 👀

@NASAWebb and @NASAHubble just unveiled this pair of colliding galaxies that are absolutely, definitely not staring into your soul. Stick around today as we share ghoulish glee from across NASA! https://t.co/BKyUGMMfny

The moon setting over the Pacific.

Went to the cupola to shoot Tropical Storm Hone near Hawaii but right after we passed by the storm the moon started to set.

Happy #WorldPhotographyDay from the world's orbiting astrophotographer!

To celebrate, we're sharing new posters highlighting some of Hubble's greatest shots.

Timelapse of the moon setting into streams of red and green aurora followed by a sunrise lighting up Soyuz with a light blue.

The aurora have been amazing the past few days. Great timing for trying out a new lens that recently arrived on Cygnus.

The Sun emitted a strong solar flare on July 13, 2024, peaking at 10:34 p.m. ET. NASA’s Solar Dynamics Observatory captured an image of the event, which was classified as X1.2. https://t.co/jD8GGyXmut

A great video to learn about tuberculosis and understand why it is still the deadliest infectious disease

4000 people died of TB yesterday!!! So that we can realize a world without TB.

Please share widely

In every project you get to the "point of creative frustration", leaving you with 4 options:
-Denial of the problem (and quitting),
-Settling for something less than adequate
-Abandoning the line of thought (and quitting),
-Just keep working and exploring until you figure it out.

[Matthew Dominick @dominickmatthew]

We have been looking at aurora out the cupola windows a lot lately. Starliner was doing some testing today so we decided to check it out from the Dragon windows. Timing was great for the aurora to line up nicely with Starliner’s service module thrusters.
