Topline results of daraxonrasib's ph3 trial for pancreatic cancer are so incredible I can hardly believe them.

Median overall survival of 13.2 vs 6.7 months with chemo, i.e. ~doubling survival.

I'd like to see the data but this may be the biggest breakthrough in pancreatic cancer we've ever seen.

I am so sad to hear about the passing of the great Andreas Engel. Beyond the many scientific accomplishments of his career, he was an amazingly kind person who helped me a lot when I started my own lab. You will be missed Andreas 💔

Dear colleagues,
With deep sadness I share the news that Andreas Engel passed away last Wednesday, at the age of 82, after a courageous fight against an aggressive caner. Only half a year ago, he was out hiking in the Italian mountains with his wife Barbara, walking 160 km in a single week. 
Andreas trained as a physicist in Bern, Switzerland, before heading to John Hopkins University in Baltimore for his postdoctoral work. He then led a research group at the Biozentrum in Basel, and in 1985 took on the role of a group leader in research and development at Ilford Ltd. in Fribourg, Switzerland.
In 1987, he joined forces with his colleague Ueli Aebi to establish the Maurice E. Müller Institute at the Biozentrum of the University of Basel. Together, Ueli and Andreas served as professors for structural biology there for almost a quarter century, leaving a lasting mark on the field of structural biology as we know it today.
 
Andreas Engel was a true pioneer. He was among the first to apply atomic force microscopy (AFM) with the tip operating under water, and one of the earliest researchers to perform 3D reconstructions using scanning transmission electron microscopy, achieving remarkable high-resolution maps of porin 2D crystals by STEM. He became a leading expert in membrane protein 2D crystallization, and his group played a key role in the determination of the first aquaporin structure, in collaboration with Peter Agre and Yoshinori Fujiyoshi. 
As he approached retirement from Basel, Andreas founded the Center for Cellular Imaging and NanoAnalytics (C-CINA) of the University of Basel, which in 2009 operated among others one of the very early Titan Krios instruments. From 2008 also held a professorship at Case Western Reserve University, Cleveland, followed by a position at TU Delft in the Netherlands in 2013. In 2020, he was among the founding members of CryoWrite, a company in Basel that he led as CEO until recently.

Truly the end of an era.
Bob Grassucci in New York was one of the pioneering cryo-EM facility managers during the field's development (along with the likes of Deryck Mills in Germany, John Berriman in the UK, Bill Tivol in California, and others). Unsung heros of the cryo-EM resolution revolution.

FACT OF THE DAY. 26 March 1953. In a huge medical breakthrough, US medical researcher Dr Jonas Salk announced that he had created the first polio vaccine. Polio cases fell from 58,000 per year in 1952 to 6,000 by 1958. Salk’s vaccine was replaced by a new one developed by Albert Sabin in 1962.
