There is not an industry on planet earth that could have gone >2 decades without a cost of living adjustment and be healthy. But that is what science is like now. I just got notice that some of our service costs are going up ~9%. Microscopes are up >300% in price over the last 2 decades. etc...
So in the last two weeks EIC of Science and a famous science communicator have lost massive amounts of credibility because of their reliance on LLMs... Some examples of how to lose trust with your audience to share with my students I guess.
RFK jr overrode the NIH recommendation for NIAID Director to appoint his own preferred candidate (who applied, but NIH declined to interview), per @politico.com. Institute directors have final say on funding decisions and are critical to the integrity of NIH. 🧵 www.politico.com/news/2026/08...

In our (chem) PhD admissions process we try to emphasize that 1) experience takes many forms, only one of which is prev training and/or pubs 2) experience is the numerator, and opportunity is the denominator. We actively look for applicants who have made the most of opportunities available to them.
I'd argue this has become even more of a problem in PhD admissions (at least in psychology) over the past few decades... programs/labs are increasingly unlikely to take promising but green students and more likely to take people who already have a demonstrated track record of skills and publishing
Just your regular reminder that: 1) Almost everyone has an underlying health issue if you look hard enough 2) People with underlying health issues don't deserve to die for eating lettuce 3) We should be strengthening, not weakening our regulatory processes. And properly funding them.
Breaking News: Two deaths in Michigan have been linked to cyclospora. Both people who had the parasite also had underlying health issues.
Give yourself some grace! Scale back on what you think you should be covering. You are learning as much (if not more) than your students the first time you teach a course. (True if this is your 1st or 20th year teaching). You’re not going to be super comfortable until your 3rd time thru.
Someone on here calls them Drop In hours, and I had luck with that.

The short version is: after a month the AI has not given me any good reasons to trust it, and I am honestly freaked out by the confidence with which it weaves completely wrong facts into prose, and the confidence with which it writes and professionally formats entire sections of bullshit.

Hey 🧪! I was just reminiscing with a friend about the time a very senior academic called a mid-career guy's work "completely meaningless" at a meeting and now I want to hear your best (public, academic) disses
From the abstract: “promoting a woman to Associate Professor increases female faculty by 1.5 members after 15 years, leads to six additional female PhD graduates over the following decade, and raises the number who subsequently remain in academia and reach tenured positions”
Fascinating paper on the progression of women in academia. 👩🏻🔬 ⚛️ 🧪 #AcademicSky docs.iza.org/dp18477.pdf?... Here's an excerpt from the conclusion:
Avocados come in 2 varieties - A-types start each day female and switch to male midday. B-types do the reverse. In work just published from the last chapter of my PhD, we show this system evolved 40+million yrs ago and is regulated by alleles of 1 transcription factor www.pnas.org/doi/10.1073/...

There's just something surreal about bicyclobutanes. Read how Justin Lopchuk and colleagues figured out how to add these strained bisected bits to covalent drug candidates. My latest in @cenmag.bsky.social #chemsky🧪 cen.acs.org/pharmaceutic...
The covalent drug arsenal gets a new warhead
A mild, modular approach to adding bicyclobutanes could bring more selectivity to these therapies

A new rule by the Dept of Homeland Security imposing visa time limits on foreign Ph.D. students and postdocs will harm U.S. science, experts warn. My latest for @statnews.com (and my first story after returning from parental leave). www.statnews.com/2026/07/28/d...

NIH is testing their ability to terminate “unaligned” grants, with at least one new termination documented. Disgustingly, they awarded this grant simply so they could add a termination clause. Then they terminated it. From @jocelynkaiser.bsky.social www.science.org/content/arti...
NIH is again terminating grants that the Trump administration dislikes
