    Adaptive Trials

    There are a lot of clinical trial designs out there. But one thing that a lot of them have in common is that they are designed right from the start to run under certain set conditions and to enroll a set number of people (or at least to meet certain thresholds before that enrollment is… Read More
  • Don’t Let Humans Pick the Experimental Conditions?

    When chemists have a wide range of reactants to choose from to make new compounds, how do they choose which ones to use? “Not randomly” is the answer, even when perhaps it should be. This effect has been noted in medicinal chemistry, where the choice of building blocks (not to mention reactions) for analog synthesis… Read More

    The Last of Stemcentrx

    The final implosion of the Stemcentrx deal is worth a note, although I said a lot of what I have to say about it back in December. I want to especially emphasize two points I made back then – first, that the failure of this whole acquisition is different only in degree, and not in… Read More
  • Sweet Almonds: One Amino Acid Did the Trick

    Well, I spent the holiday weekend here sending out pictures of food on my Twitter account, so I suppose it’s only fitting that I blog about a related topic today. But it also touches on metabolic enzymes, transcription factors, and death by cyanide, so there’s something for most everyone. I refer to this paper which… Read More
  • Fast Pain Relief – In Only Seven Million Years

    Here’s a chemical descriptor that I didn’t know: algogen, meaning a molecule that causes pain. I would have classified the natural product I did my PhD work on as one, since it caused me substantial pain at the time, but this term refers more properly to physical nociceptive types of pain, rather than the intellectual… Read More

    Autism Mouse Models for the Microbiome?

    Many readers will have seen the paper that just came out on a possible mouse-model demonstration of a connection between autism and the gut microbiome. It’s certainly generated a lot of headlines, and its very title guaranteed that it would: “Human Gut Microbiota from Autism Spectrum Disorder Promote Behavioral Symptoms in Mice“.… Read More

    VCAM1 As a Player in the Aging Brain

    Possible intervention targets for age-related degeneration are always welcome, particularly when they come bearing experimental evidence, and even more so when they relate to the central nervous system. That’s the case with this new paper, from a multicenter team led out of Stanford. Interestingly, this also ties in with the well-publicized … Read More

    Vibrational Modes, For Real

    I suppose I deserve this one. Some years ago on the blog, I wrote about my days in grad school having to learn about symmetries and vibrational spectroscopy. Sparingly has that knowledge come in handy since then, but the course is still a vivid memory for me, since that’s the clearest example I had yet… Read More

    An Expensive Choice for Duke

    You may have seen the headlines about a large settlement ($112.5 million) that Duke University is paying the government. This goes back to Erin Potts-Kant, a clinical research coordinator at Duke Health, as well as (former) professor William Foster and (former) chief of the Pulmonary Division Monica Kraft. The details are many, and some of them… Read More

    Sneaking Proteins Into Cells

    Now here’s a weird and rather startling paper. One of the things that people in this line of work spend a lot of time on is getting things into living cells. Small molecules often slide in, one way or another (although, to be honest, our detailed understanding of how they do that could use some… Read More
