Niche vent but VERY frustrated that we still don't have the engineered anti-spike T cells that are engineered for resistance to antimetabolite immunosuppressants for immunocompromised people in clinic

The last day of meteorological summer - & my last day at the University of Portsmouth - and it is raining.

I'll miss the commute into the Uni: a 20-minute bicycle ride and then a ferry trip across the Solent. There is always something to see on this short stretch of water.

I was just showing these new #JWST data to our team yesterday. Apparently they've already been making the round on X, so I might as well share my own version:

Left: HST F814W filter; Right: RBG image in 3 JWST filters. I lack the skills to make it pretty but check out the southern component! 1/4

Ok, one last thing because supernovas are awesome.

Here is a timelapse showing how the SN 1987A supernova remnant has changed over time. We see the effects of a shock wave from the supernova blast smashing into the ring, which is about one light-year across. The ring brightens, revealing clumps of previously ejected material as the shock wave hits it.

The FBI just responded to a FOIA request about Daniel Ellsberg with more than 5,000 pages of historical documents. They're all public here, please take a look if you're interested https://www.muckrock.com/foi/united-states-of-america-10/daniel-ellsberg-records-federal-bureau-of-investigation-147868/#files

Micah Lee made this request to Federal Bureau of Investigation of the United States of America.

AstroKatie -

...we find larger grains close to AGN as smaller grains are preferentially removed by photo-destruction; fractional 3.3 to total PAH is enhanced in SF regions; and 3.3um PAH-based SFR could be underestimated by up to 2x in composite AGN+SF systems at high z. Check out the paper for more!

Welcome to several new followers!

Instead of a typical intro, I'll reveal something unique about myself: I started in planetary science as an amateur.

I am what happens when spacecraft missions release their data to the public.

I went from image processing, to reading up on Titan literature, to going to planetary science conferences during vacations, to transitioning from a 20-year pharma career to a NASA senior postdoc in planetary science at JPL, to current job as scientist at JPL.

Jupiter's largest moon, Ganymede, is bigger than planet Mercury -- and is blanketed in thin clouds of hydrogen peroxide, as seen in a remarkable new image from JWST. https://news.berkeley.edu/2023/07/27/james-webb-space-telescope-sees-jupiter-moons-in-a-new-light/ #space #science #JWST
James Webb Space Telescope sees Jupiter moons in a new light

NASA’s new space telescope uses its high-resolution spectrometer to find hydrogen peroxide around Ganymede’s poles and sulfur monoxide emerging from Io’s volcanos
