NSAIDs are known to alleviate pain by reducing inflammation. A study in Nature Communications shows that selective inhibition of the prostaglandin E2 receptor in Schwann cells eliminates pain without disrupting the protective and healing functions of inflammation. #medsky 🧪
Targeting prostaglandin E2 receptor 2 in Schwann cells inhibits inflammatory pain but not inflammation - Nature Communications
Non-steroidal anti-inflammatory drugs (NSAIDs) are known to alleviate pain by reducing inflammation. To the contrary, here, the authors show that selective inhibition of the prostaglandin E2 receptor (EP2) in Schwann cells eliminates pain without disrupting the protective and healing functions of inflammation.

Prevention of type 2 diabetes through prediabetes remission without weight loss - Nature Medicine
A post hoc analysis of a multicentre, randomised trial showed that prediabetes remission is possible without total weight loss—providing weight is distributed to subcutaneous deposits as opposed to visceral ones.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.
The effect presumably comes from the absence of S-cones in the fovea.

1. Read them ahead of time.
2. Ask for help
3. Forvo.com is a great resource
4. Slow down, and use falling tones to give extra gravitas.
5. Apologize and own mistakes

A challenging paper I'm looking forward to reading. I believe more strongly than I can say in the need to create a positive vision for models and how people use models that is a part of *science* rather than "product." As people in the tech industry we have a responsibility for this.

Scientists who study climate don't automatically attribute all changes to human activity. Rather, we carefully investigate every possible natural factor that could explain the planet's warming.
Could these be the real culprits?
The evidence is in--and the answer is NO.

Effective Learning Strategies.
A focused class on how people learn, study, and memorize. A kind of health class for the educational process that encouraged students to think critically about how they're managing their studies in other classes and why things do or don't work for them.
