Out now in Science! Our study challenges long-standing assumptions about transcription factor specificity in eukaryotes. Novel single-molecule measurements of TF behavior in living cells reveal an independence of locus-specific binding from DNA sequence recognition.🧵 www.science.org/doi/10.1126/...

Unstructured transcription factor interactions enable emergent specificity

How intrinsically disordered regions (IDRs) shape chromatin binding and nuclear organization of transcription factors (TFs) remains unclear. We used proximity-assisted photoactivation (PAPA), a single...

Unreliable and underperforming antibodies are a longstanding problem, so while the reveal of apparently manipulated antibody data in Thermo Fisher's catalog was a shock, the frustration it sparked among many researchers is perhaps no surprise. My reporting:

Science sleuths uncover more than 100 suspicious images in Thermo Fisher antibody catalogue

Scientists have long worried about the reliability of commercial antibodies, and the latest findings have sparked fresh concerns.

CIHR has launched a trial ballon that suggests shifting to one competition a year. This is the worst idea I have heard in a long time. The only benefit is making top-line success rates look better than they are. Keep it as is, do in-person reviews, and keep the pain in the open.

Today in the 🇨🇦 National Grad Course in Islet Biology and Diabetes we are joined by experts @ejrideout.bsky.social and Jee Yeon Cha (Vanderbilt U) to discuss sex-dependent phenotypes and responses in chronic disease, autoimmunity, and diabetes. A dynamic lecture for a dynamic field!
