Can report the students are wicked smart😎.
Also learned a lot of new things that I have missed on my first Analysis rodeo ~20 years ago.
You indeed understand something when you can teach it!

Study section that was cancelled due to shutdown is rescheduled for early January next year.
Two days will be compressed to one day. That will be superintense.
I have 7 applications to present, will try my best to stay sharp🫡

I am dreading a post-antibiotic world, so this sounds awesome!
British and Australian chemists have discovered a powerful new antibiotic called pre-methylenomycin C lactone, hiding in a well-known soil bacterium. This molecule kills drug-resistant bacteria without triggering resistance. buff.ly/YlXaONo

Scientists find hidden antibiotic 100x stronger against deadly superbugs
A team of scientists discovered a hidden antibiotic 100 times stronger than existing drugs against deadly superbugs like MRSA. The molecule had been overlooked for decades in a familiar bacterium. It…

Felix Zhou's u-Segment3D is out:
www.nature.com/articles/s41...
It leverages 2D cell segmentations from orthoviews to generate a ‘consensus’ 3D segmentation.
It does a great job on segmenting densely packed samples, and we have used the algorithm in many applications.

Enviable discipline in the @kevin-dean.bsky.social lab:
While Kevin is far away discussing the future of microscopy, his lab meeting is carried out independently.
I snapped the first slide for illustration of the seriousness of the business discussed (suppl. Figure 2: zoom-in).

Thrilled to announce the launch of my lab
@cri-utsw.bsky.social at UTSW this January!
We will explore how cells sense and respond to mechanical forces, focusing on membrane mechanics to reveal how tension and signaling work together to shape cell behavior.

We're growing! Our newest Investigator @henrydebelly.bsky.social will join the CRI Tissue #Regeneration Program in January 2026. Learn more about Henry ➡️ cri.utsw.edu/faculty/henr... and 📌apply to research in his lab cri.utsw.edu/careers

I have now received an official NIH email that the study section tomorrow is off😞.
I have a study section scheduled this week. Any chance it will take place?
SRO has not replied for days. Submitted 7 critiques on time nevertheless.
