Meiosis-specific functions of kinetochore protein SPC105R required for chromosome segregation in Drosophila oocytes biorxiv.org/content/10.1101/…

Meiosis-specific functions of kinetochore protein SPC105R required for chromosome segregation in...

The reductional division of meiosis I requires the separation of chromosome pairs towards opposite poles. We have previously implicated the outer kinetochore protein SPC105R/KNL1 in driving meiosis I...

Magnetic Isolation and Concentration (MagIC)-cryo-EM is a new method to enable direct structural analysis of targets captured on nanomagnetic beads, which requires only 0.0005 mg/mL of targets in 100 µL crude solution to make 10 cryo-EM grids. I will explain the magic behind it!

Very happy and proud to share the work PhD student Joana Lima @i3S_UPorto “A nuclear signal in prophase determines centrosome positioning and ensures efficient mitotic spindle assembly”, now online. biorxiv.org/content/10.1101/…

A nuclear signal in prophase determines centrosome positioning and ensures efficient mitotic...

Accurate centrosome separation and positioning during early mitosis relies on force-generating mechanisms regulated by a combination of extracellular, cytoplasmic, and nuclear cues. The identity of...

The Ndc80-Cdt1-Ska1 complex constitute a minimal processive kinetochore-microtubule coupling unit

The Ndc80 kinetochore complex is essential for robust kinetochore-microtubule (k-MT) attachments during mitosis. Ndc80 has been shown to recruit the Ska1 complex to kinetochores, where Ska1 is...

Spindle assembly in Xenopus egg extracts! Videos were taken while working late into the night at @MBLScience with Aaron Groen and @GatlinLab. The montage is from our (@viktzv) recent retrospective in @MBoCjournal on a seminal paper by @rebeccaheald. ow.ly/GTsW50HHlPY

Wish we could think seriously about the authors suggestion of an A/A-/Pass/Fail model, which is effectively the med school grading scheme.
Never knew Orville Wright had to fight his whole life (on behalf of he and his brother) for the Smithsonian to recognize they invented the airplane. washingtonpost.com/history/2…

Wright brothers vs. Smithsonian: The bitter feud over who invented the airplane

The Smithsonian gave credit to its director, Samuel Pierpont Langley, whose plane crashed into the Potomac River shortly after takeoff. The Wrights were not pleased.

Favorite line from the article: “Orville Wright died of a heart attack in January 1948. He had seen plane speeds go from 6.8 miles per hour on his first flight to 662 mph in 1947, when Air Force Capt. Chuck Yeager broke the sound barrier.”

Punchline: optogentically oligomerized KNL1 recruits PP1 to microtubules in mitosis. KNL1 oligomers can bind microtubules and PP1 simultaneously. The Cry2 oligomerization tag - developed in the Schaffer lab @UCBerkeley and used in @brangwynnelab OptoDroplet assay - is powerful!
