Thanks @spencersoicher.bsky.social @nexton9news.bsky.social for a story on the importance of environmental contamination, site clean-up and of course, microbes!🦠 🦠

Here's what the remediation for environmental issues may look like at Burnham Yard

The historic railyard likely contains subsurface contamination from decades of industrial use that will need to be addressed before the planned stadium.

Never ceases to amaze how one can pull an entire lab out of 2 closets; conduct and teach science to 20 Amazing! students at the Microbial Diversity Course and have great science produced @mblscience.bsky.social
…stay tuned for publications….

I once had a joyful evening in the Ed Sullivan Theater watching magic happen in front of me. An educated, civil, democratic society values the jesters—Stephen Colbert is a master teacher we all learn from.

Apparently CBS Paramount does not, enhancing our decline.

Week two on Microbial Diversity. One of our course directors, John Spear, spoke about H2 and sulfur metabolism, including his adventures doing research in caves.

A media extravaganza at Microbial Diversity ‘25 @mblscience.bsky.social difficult to pull off anywhere—Thank you Juan Parales et al.!

Thanks!

Hey George—took it last year, Jenn is TA-ing this year. We are almost ready for mayhem to start tomorrow evening. Hope all is well your way!

At @mblscience.bsky.social preparing for Microbial Diversity ‘25; takes a lot of preparation for both aerobic and anaerobic cultivation of amazing microbiota from diverse environments.
(and yes, this is what this course has ‘diversity’ in the title…)

When doing field work, or being anywhere, always important to pay attention to your surroundings. Nice writeup on Biscuit Basin @yellowstonesv.bsky.social 2024: eos.org/features/hyd...

Hydrothermal Hazards on Display in Yellowstone National Park - Eos

Tourists and officials were startled by a hydrothermal explosion at Black Diamond Pool in July 2024. Geoscientists are working out how and why it occurred to better understand these hazardous events.

If you are into subsurface microbiology, hydrogen and serpentinization, this is a great read (in my biased opinion) from Dan Colman.
See what you think!
