a large, fluffy pup sits on her human's lap outdoors. she's looking straight ahead while being held like a child. her feet are up and her toe beans are spread wide, presumably for tanning purposes.

This is Comoong. She has a whole dog park to run around in. Prefers to sit like this the entire time instead. 13/10 (IG: comoongpark)

Molecular glue degraders are more versatile than previously thought Study by biotech firm Monte Rosa finds that they can target a wider variety of proteins

More proteins may be druggable with molecular glue degraders than initially thought, according to a new paper in Science from the biotech firm Monte Rosa Therapeutics. cen.acs.org/pharmaceutic... #chemsky ๐Ÿงช

Sounds so interesting! I should have attended this conference. Since I work on tattoos, it would have been right up my alley.

Let's talk about these two department store owners: brother and sister Louis Bamberger and Caroline Bamberger Fuld. From Newark, New Jersey.

They are random people, basically. But in the late 1920s, with fascism taking over Europe, they made a choice that profoundly changed the world: ๐Ÿงต

Defluorination is Happening Inside You Right Now

People have occasionally found microbes that can actually break carbon-fluorine bonds, as unlikely as that may seem. What's even more surprising is that we have some of them in our own intestinal flora!

Itโ€™s been a tough few weeks. My 10yo daughter was diagnosed with a very rare, aggressive cancer called interdigitating dendritic cell sarcoma (IDCS). Iโ€™m reaching out to identify clinicians/patients who have encountered pediatric IDCS or other (non-LCH) dendritic or histiocytic sarcomas cases.

Interesting discussion! Though it is focused on computational chemistry, a similar discourse could happen in any other field of chemistry.

Sad news. I was fortunate to meet Sir Fraser during my postdoc at IU Bloomington in 2019. A brilliant scientist in our field. My heartfelt condolences to his family.

Programming the Kinetics of Chemical Communication: Induced Fit vs Conformational Selection Life on Earth depends on chemical communication and the ability of biomolecular switches to integrate various chemical signals that trigger their activation or deactivation over time scales ranging from microseconds to days. The ability to similarly program and control the kinetics of artificial switches would greatly assist the design and optimization of future chemical and nanotechnological systems. Two distinct structure-switching mechanisms are typically employed by biomolecular switches: induced fit (IF) and conformational selection (CS). Despite 60 years of experimental and theoretical investigations, the kinetic and evolutive advantages of these two mechanisms remain unclear. Here, we have created a simple modular DNA switch that can operate through both mechanisms and be easily tuned and adapted to characterize its thermodynamic and kinetic parameters. We show that the fastest activation rate of a switch occurs when the ligand is able to bind its inactive conformation (IF). In contrast, we show that when the ligand can only bind the active conformation of the switch (CS), its activation rate can be easily programmed over many orders of magnitude by a simple tuning of its conformational equilibrium. We demonstrate the programming ability of both these mechanisms by designing a drug delivery vessel that can be programmed to release a drug over different time scales (>1000-fold). Overall, these findings provide a programmable strategy to optimize the kinetics of molecular systems and nanomachines while also illustrating how evolution may have taken advantage of IF and CS mechanisms to optimize the kinetics of biomolecular switches.

Have a look at the TOC graphic - Nice and simple design but also fairly self-explanatory. Love it!

a white fleece blanket with black spots is puddled up on a light-beige chair. part of the blanket seems to rise up from the seat, defying gravity, as if itโ€™s propped up on something. some of the spots near the top are irregular, resembling two eyes (one brown and one blue) and a black nose on a dalmatianโ€™s face.

Haha very funny guys. Sending in photos without dogs in them. Thought we just wouldnโ€™t notice? Hilarious. Still 12/10 for the blanket
