Potential biosignature on Mars: confirmed. ✔️ After a year of scientific review, we are more sure than ever that our Mars Perseverance's 'Sapphire Canyon' sample could contain signs of ancient microbial life. Learn more about the discovery: go.nasa.gov/46jy4hL

Our team recently worked with Toi Moana Bay of Plenty Regional Council's Harbourmaster to test new ways of monitoring gases at Whakaari/White Island — this time, from a vessel. Check out how the team made it happen 👇 geonet.org.nz/news/1p9KGVbJO…

Most MATLAB users know that you should do y = A\x instead of y = inv(A)*x. One user found cases where inv() was faster! We investigate on The MATLAB Blog 👉 spr.ly/6017ABgCF

Very sad 😢tragic explosion in Tennessee 😢 Forensic Seismology: Application of seismology to investigate (and hopefully mitigate the impact of) social, legal, political, and/or security implications of seismic events (usually non-earthquake events).
