Hello, Moon. It’s great to be back.

Here’s a taste of what the Artemis II astronauts photographed during their flight around the Moon. Check out more photos from the mission: https://t.co/rzM1P0QbOl

Lock in, we’re Moonbound.

Artemis II astronauts are more than halfway to their destination, and preparations for lunar flyby are underway. During their trip around the far side of the Moon, they will capture imagery to share with scientists (and you, too!).

Researchers at MIT have captured, for the first time, the dynamic process that marks the very beginning of life: when an egg cell is fertilized, it triggers waves of activity that ripple across its membrane.

These waves act like a biochemical signal, initiating the complex sequence of events that drives the cell to start dividing and developing into an embryo.

@bennbuilds Hei Ben! I'd like to ask you a few questions, to publish a short interview on my website (https://t.co/yRYMP7hSJ2) and probably also on a regional newspaper. Would you be up for it?

6/ Taxonomy is a pragmatic workaround, not a solution.

Science mitigates ambiguity by categorizing entities and detailing their properties. This organizes knowledge effectively, but it doesn’t resolve the core metaphysical question: what makes something alive?

[Danilo Calcaterra @Dan_Calcaterra]

5/ Material comparisons fall short.

Detailed chemical and structural analyses identify many traits, but every attempt to create a universal checklist produces exceptions: things left out, or things included that seem plainly nonliving.
