Remembering my father, Ahmed Zewail (1946–2016), Nobel laureate and pioneer of femtochemistry. An Egyptian-American scientist whose groundbreaking work changed how we see molecules. His legacy continues to inspire scientists around the world.

Chemical reactions take place in a matter of femtoseconds. One femtosecond is to a second, as a second is to 32 million years.
#NobelPrize laureate Ahmed Zewail used lasers to watch these reactions in slow motion and study how atoms in a molecule move during a chemical reaction.

Happy to share @radhikaRMalik & co.'s paper in @NatureSMB. Using #cryoEM of the Rev1-PolZ holocomplex, they reveal the basis of its cooperativity in TLS. They discover the N-helix-BRCT module as a keystone of this coordination. @NCCATinfo @IcahnMountSinai

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!

WFH is the new normal. Tech companies are reevaluating if behaviors such as business travel, expensive offices, etc are as efficient following the pandemic. I will say for the human soul, wfh isn't as beneficial. But my friend Alex said it best (see below):
