📣New preprint alert!
Check out this new preprint by Zhu et al. that quantifies and compares labile exometabolites from six axenic strains of marine phytoplankton 🌊 to identify key chemical currencies within the marine chemical-microbial network! 🧪🦠

A graph of atmospheric carbon dioxide concentrations at the Mauna Loa observatory, Hawaii, from 1958 to 4th February 2025. It shows carbon dioxide levels rising at an accelerating rate over the decades. This is known to be due to emissions of carbon dioxide from human activity, mainly fossil fuel burning but also deforestation. The first CO2 concentration value in March 1958 was 315 parts per million (ppm). The latest daily value is 426 ppm. The graph also shows a seasonal cycle of a few ppm within each year, which is known to be linked to the growing season in the northern hemisphere causing a temporary uptake of carbon in spring and summer and release in autumn. The graph is produced routinely by the Scripps Institution of Oceanography, UC San Diego.

Although NOAA's page on atmospheric CO2 levels has vanished, you can still get this vital information from Ralph Keeling's team at the Scripps Institution of Oceanography, UC San Diego keelingcurve.ucsd.edu

Screening performance and characteristics of breast cancer detected in the Mammography Screening with Artificial Intelligence trial (MASAI): a randomised, controlled, parallel-group, non-inferiority, ... The findings suggest that AI contributes to the early detection of clinically relevant breast cancer and reduces screen-reading workload without increasing false positives.

New: The largest medical A.I. randomized controlled trial yet performed, enrolling >100,000 women undergoing mammography screening
The use of AI led to 29% higher detection of cancer, no increase of false positives, and reduced workload compared with radiologists w/o AI thelancet.com/journals/lan...

This is as good a time as any to revisit the history of the creation of the NSF. It was inspired by a request from FDR after World War II to Vannevar Bush (Matthew Modine in "Oppenheimer"), who responded in a classic letter now known as "Science: The Endless Frontier". It is very inspiring.
