There's been a lot of discussion lately around mRNA vaccines.

Learn about them from mRNA researcher & Nobel Prize winner Prof. Katalin Karikó.

Science, solutions & solidarity.

Lots of folks will be all about green smoothies, vitamins, sunglasses, sun hats, health tracking apps & watches, yoga, supplements, the gym.

But the minute you mention masks as a health precaution, they have a total
meltdown & refuse to do that

This is the interstellar comet 3I/ATLAS, imaged on 21 July by the Hubble Space Telescope.

It continues to blow my mind that this comet is from a different planetary system, and is likely more than seven billion years old.

4/8/22, WNYC: "Why We Should Have Seen Long COVID Coming"

'..tens of millions of people have experienced Long COVID...Brooke talks to Laura Spinney about Long influenza, post-polio syndrome, and why long term illnesses escape a neat pandemic narrative.'

At West Virginia University and University of Nevada, researchers found that certain SARS-CoV-2 spike protein fragments form amyloid-like oligomers, but only one (s192) damaged brain lipid membranes, hinting at a possible role in long COVID.

apropos of nothing, the Parks Department calendar is the best resource in the world. everything listed on there makes me want to close my laptop and go on a walkabout ... and it's all free

anyways go learn about our urban waterfalls this weekend!!

Teachers: This fall, bring your students to Mount Wilson Observatory for an unforgettable NGSS-aligned STEM field trip—where Einstein, Hawking & Sagan once stood. Science comes alive where history was made!

(h/t to @dougellison.bsky.social for making my late night request to acquire this Navcam postcard a reality. The view was too good!)

With seven months of the year now in, 2025 is on track to be the second or third warmest year since records began in the mid-1800s, with a slightly higher likelihood of being the third warmest.

This is a really good thread by @masknerd.bsky.social. Dead on and worth the 90 seconds to read. 👇

Validation of the age, neutrophil to lymphocyte ratio, C reactive protein score on 28 day mortality in the National COVID cohort collaborative - Scientific Reports Scientific Reports - Validation of the age, neutrophil to lymphocyte ratio, C reactive protein score on 28 day mortality in the National COVID cohort collaborative

Chapel Hill researchers studied 9,708 hospitalized COVID-19 patients and found that a simple ARC score—age, neutrophil-lymphocyte ratio, and CRP on day 3 predicts 28-day mortality with 77% accuracy, aiding bedside risk assessment.

adding SARS-CoV-2 Mpro (in red, purple, blue, gray, little green) to a test tube with pink plasma, causes activation of VII and XII (red circles) to make a blood clot (RBCs with yellow platelets and yellow fibrin)

🩸A new study shows that adding SARS-CoV-2’s main protease (Mpro) enzyme to plasma from healthy donors can trigger blood clots by activating coagulation factors VII and XII. buff.ly/hWZB7aS

🩸This may help explain why COVID increases blood clot risk.

An area of deep space with thousands of galaxies in various shapes and sizes on a black background. Most are circles or ovals, with a few spirals. More distant galaxies are smaller, down to being mere dots, while closer galaxies are larger and some appear to be glowing. Red and orange galaxies contain more dust or more stellar activity.

For the latest image of the month, the NASA/ESA/CSA James Webb Space Telescope revisits the iconic Hubble Ultra Deep Field.

The deep observations reveal more than 2500 sources sparkling in this tiny patch of sky ✨

German researchers followed 74 children with long COVID for up to 3 years and found that stable symptoms were driven by shifting immune-metabolic responses, revealing biologically distinct subtypes tied to EBV exposure and immune markers like IL-12p40.

You wouldn't drink dirty or contaminated water that would make you sick... So why would you breath dirty or contaminated air that would make you sick?

You filter your filtered water. A person drinks about 3.2 liters of water per day. Why not filter your air? A person inhales about 11,000 liters of air per day.

Clean the air. We cleaned the water when we found out dirty water gave us cholera & other issues. But we refuse to clean air in buildings or what we breathe even though both air pollution & airborne virus are known to be bad.
