Cosmic dust reveals dynamic shifts in central Arctic sea-ice coverage over the past 30,000 years
Arctic sea-ice loss affects biological productivity, sustenance in coastal communities, and geopolitics. Forecasting these impacts requires mechanistic understanding of how Arctic sea ice responds to ...

No astronomy per se in this week's issue of @science.org, but there is a fascinating study by Pavia et al. that uses cosmic dust to trace sea ice coverage in the Arctic. 3He from micrometeorites records when the ocean was ice free, over the last 30,000 years. 🧪🌊

The NSF cuts are nothing short of a scorched-earth attack on US science, orchestrated w/political cynicism & total disregard for US scientific leadership. A 7% success rate doesn’t incentivize innovation; it tells researchers to take their talent elsewhere.

Trump administration cuts to NSF will result in more than 200,000 FEWER people per year involved in basic science, training, and education - what should have been the next generation of US scientists. This isn't even eating your seed corn, it is setting your seed corn on fire and salting the earth.
