How can we interpret signals from extraterrestrials when we struggle to communicate amongst ourselves?

My new book (out now in the UK, out in the US on Jan 13) "Mixed Signals" delves into how the Cold War forged SETI and radio astronomy as we know it.

At AIP we've launched a new policy research program to go deep on current questions and pull together more comprehensive pictures. Leading this work, Lindsay Milliken has produced her first public product, a primer on the new $100,000 fee on H-1B petitions.

Despite working in a time of tense diplomatic relations, proxy wars, and budget cuts, many US and Soviet scientists collaborated productively during the 1970s and 1980s, writes Anna Doel. Prior exchanges help better understand the challenges to scientific cooperation today.

Research exchanges between US and Soviet scientists during the second half of the 20th century may be instructive for navigating today’s debates on scientific collaboration.

A huge loss for NASA science.

Another self-inflicted wound to our national science portfolio.
David Grinspoon confirms that his term appointment as NASA's Senior Scientist for Astrobiology Strategy will not be renewed and the position itself is being eliminated. He'll participate in Wednesday's Astrobiology Update (which is listed on our Calendar).

It gets worse and worse.

If you're interested in the slow-motion train wreck that is Avi's sci-comm on this, here are some of the latest (it's very hard to keep up!)

In which spacecraft can have comae, 3I/ATLAS has a 60% chance of being alien, and new papers validate and adopt his calculations.

I've long been a fanboy of the Cambridge HPS / National Maritime Museum Board of Longitude project. It recovered a rich institutional history from a heavily mythologized narrative and digitized the board's papers too. Its capstone book is an excellent contribution to #histSTM & #scipol studies.
