🍺 Fixing brewing #Yeast! 🧬 Experimental evolution corrects mother-daughter separation defects in ale strain over 200 generations:
✅ fewer large clusters
✅ reduced foam accumulation during fermentation

The Multifaceted Role of Rad9 in the DNA Damage Response of Saccharomyces cerevisiae To maintain the integrity of the genome, cells have evolved a complex signalling system, termed the DNA damage response (DDR), which detects DNA damage and promotes DNA repair. To date, over 600 prot....

In the latest #Yeast review article, A. Kiely, F. O'Halloran, P. Young, N. F. Lowndes, @murielgalway.bsky.social and K. Finn discuss the latest advances in understanding the versatile role of Rad9 in the DNA Damage Response in Saccharomyces cerevisiae 🧬

Interaction of C. glabrata wild type and C. albicans yeast-locked efg1ΔΔ/cph1ΔΔ mutant cells with macrophages.

Interaction of C. glabrata wild type and C. albicans yeast-locked efg1ΔΔ/cph1ΔΔ mutant cells with macrophages.

Should I stay or should I go? Research in #mBio suggests the fungus Candida glabrata may actively prolong the part of its life spent inside macrophages, which could contribute to immune evasion, antifungal resistance and potential recurrence of infection. asm.social/2Q2

In new research, Yu-Ying Phoebe Hsieh, Ian O’Keefe, Ajai Dandekar, Harmit Malik &co reveal how magnesium sequestration by C. albicans enables P. aeruginosa to evolve much higher levels of resistance to colistin (a last-resort #antibiotic).

David Botstein passed away. I worked with him at Stanford for a few years in designing and teaching a course on "The Heart". My heart is heavy right now. He was a wonderful mentor.

Only met him a couple of times (at CSHL and a yeast meeting). Seemed like a decent person, he was the postdoc advisor for my grad school advisor. Always joked that Botstein was my scientific uncle.

Today I get to talk about barley and the evolutionary history of domestication leading to the varieties we have today.

Plus malting: leveraging nature for our own purposes.

Best part of teaching the Biology of Brewing Course , besides the students, is talking about history and the importance of the brewing industry in society…biologically at least, we aren’t hitting on societal issues in any depth.

Guinea-Bissau officials stop CDC-funded hepatitis B vaccine trial The country's foreign minister told Reuters the controversial trial is "not going to happen."

BREAKING NEWS: Unethical, CDC Infant Hep B Vaccination Study Cancelled!

The study was cancelled after Stand Up for Science held a closed door briefing with Congress last week, with an investigator on the ground in Guinea Bissau.

In case you missed it: our review titled "Spatial structure: shaping the ecology and evolution of microbial communities" is out! 🚨

Let me hit you with some highlights on why spatial structure matters. (and why you should care!)

Much preferred giving students time and resources to develop well constructed arguments and not superficial responses under time constraints.

Are these independent isolates? Look extremely close in size, is this usual for rust fungi? The yeast we are studying vary remarkably in ITS region size.
