A recent survey from RAND found more than 1/2 of US students are using AI for school, an increase of 15% this yr compared to just 2 yrs ago.
At the same time, 61% of parents believe AI will harm students' critical thinking compared to just 22% of school district leaders.”🧪

The visible universe contains about a trillion galaxies, in a dizzying variety of styles.
The blue scatter at bottom is Leo P, a nearby dwarf just one-millionth the mass of our Milky Way. It's almost pure hydrogen & helium, much like the galaxies of long ago. 🧪🔭

Three ways of looking at the iconic Christmas Tree Cluster, 2700 light years from Earth.
What the universe looks like depends on how we look at it. These views highlight infrared (left), x-rays (middle), and red emission from hydrogen gas. Beautiful in three different ways. 🧪🔭

Happy Belated Birthday to Anthony Fauci!
Without truth, Democracy falls apart.
For Christmas I want
1. #NIH & CDC to use evidence based science
2. RFK Jr Impeached
3. MAHA dismantled
4.To not politicize science
