In her latest opinion piece, ARC CEO Prof Ute Roessner AM FAA reflects on Prof Richard Robson's journey from early research funding to a Nobel Prize in Chemistry, and what it tells us about the importance of investing in discovery research: www.innovationaus.com/richard-robs...

NASA picture of the day today is a real 🏴󠁧󠁢󠁳󠁣󠁴󠁿beauty! This is a composite image of the ~5000yo Callanish Stones on the Isle of Lewis.

The imposing Callanish Stones stand talk with their shadows spanning out across the glass.  It's a super clear sky, but looks cold. Above the central stone is a strange figure-of-8 shape of dots.  This is the location of the Sun, at noon, on various different days across the year.

Architects Unveil New Way To Make Use of Heat Waste From Data Centers
As artificial intelligence (AI) fuels a global boom in data center construction, one architectural firm is proposing a new hybrid building design that reimagines how energy-hungry data centers can better serve the communities that host them. Designed by U.S.-based architecture firm FORMA, the "Pink Thermal Baths" concept combines a public bathhouse with a data center, using heat generated by computer servers to warm its pools and bathing facilities. The project's website describes it as a new building type that pairs "the leisure activities of a bathhouse with the utilitarian functions of a data center," while keeping the data center itself "fully subterranean and hidden from sight." Read More on Travel Miroslava Brooks, founder partner at FORMA, told Newsweek that waste-heat recovery from data centers already exists, and this project imagines “pushing this logic further architecturally” by combining a data center with compatible public uses such as thermal baths and swimming pools. According to the project’s website, the excess heat from the servers is distributed to the pools, “providing a hot spring-like experience," while the cone-shaped rooms help regulate interior temperatures and create a sense of monumentality. The project is envisioned as “a kind of new hybrid building type,” Brooks said,...

Friends — did you know that Jesse Jackson was a speaker at the 1st National Conference on Minority Participation in Earth Sciences? This 1972 USGS event sparked a lot of great work before R’s decided to shut it down. I was surprised when I learned of his participation-maybe you are too.
Black and white photo of Jesse Jackson, taken by Don Carl Stefan in 1972. It is a head and shoulders shot of Jackson, arms crossed and looking over his left shoulder and st something off frame to his left. 

Jackson here is a young, black man dressed in a dark, collared shirt, light vest. He has a medium-length Afro and a mustache. He is sporting a button that reads “Ingreso adecuado ahora” which means adequate income now.
