Plants can synthesize mimics of the insect molting hormone 20-hydroxyecdysone (20E) to defend against pests. In this preprint, we discover that two plant families independently evolved biosynthetic gene clusters to make 20E. Amazing team effort by my lab! www.biorxiv.org/content/10.6...

Do you know what happens when you touch a carnivorous sundew plant? If the touch is strong and large enough, a cytosolic calcium wave will spread from the site of touch throughout the whole plant, but if you only touch one tentacle (see post below), the calcium wave will be local and less intense.

Scientists, please take a moment to comment on these plans to limit animal testing in drug regulation and biomedical research. Use whatever experience you have to make your comments specific to you. The law requires regulators take these comments into account, so it might help. Mine is attached.
I am a full professor of pediatrics at the University of Chicago, and a world renowned expert in artificial intelligence and molecular biology, particularly AI and drug discovery.  I obtained a Ph.D. in artificial intelligence (computer science) from Yale University in 1989, was a staff scientist at NIH from 1989 to 2000, when I moved to the University of Colorado School of Medicine to become a professor of Pharmacology. I have published more than 200 scientific papers and hold two US patents.  In addition to my faculty position, I am also the chief technology officer of TenZero Biosciences, an early stage drug discovery company.  Not incidental to this letter, I am also a frequent volunteer participant (subject) in clinical trials. 

I have spent my career trying to create artificial intelligence systems that facilitate the discovery of new pharmaceuticals.  In 2003, I won the American Association for Artificial Intelligence's Engelmore Prize for Innovative Applications of AI for my work in AI and molecular biology.  In that talk, I proposed a better version of the "Turing Test" for whether a computer system is actually intelligent would be one getting credit for inventing a new drug.  We are quite close to that mark now, with InSilico's Rentosertib in phase II trials. I am proud of our industry's ability to realize that vision from 20 years ago, and of my small part in that progress.   

The excitement of the first AI-discovered drug is wonderful, but should not be taken as evidence that AI is ready to usurp the FDA's traditional regulatory role. Even under the current very stringent regulatory scrutiny, mistakes are made that cost lives. Rofecoxib is perhaps the most obvious example, but there are of course many others.  There are many published methods to assess the safety of novel compounds for human beings, including ones based on AI.  However, none of them are perfect. The complexity and diversity of human biology means that the effects of novel compounds on …
