Teens may have come up with a new way to detect, treat Lyme disease using CRISPR gene editing To compete at iGEM, a sort of science Olympics, teens at a Georgia high school set their sights on finding a better way to detect and treat Lyme disease. Their approach uses CRISPR gene editing.

Remarkable story of a Georgia high school team who used CRISPR to make a rapid diagnostic test strip for Lyme disease, speeding dx from 2 weeks to days

Figure 2. Change in bodyweight
(A) Mean percent change in bodyweight from baseline to week 48, shown as observed means and bars indicating SEs. The model-based estimates of the mean percent change in bodyweight and differences among treatment groups at week 48 with the corresponding p values (efficacy estimand only) and 95% CIs are shown in (B) (efficacy estimand) and (D) (treatment-regimen estimand); bars indicate SEs. Multiplicity adjustment was not performed, and p values should be interpreted as exploratory. (C) shows the percentage of participants with bodyweight reductions of at least 5%, 10%, 15%, 20%, 25%, and 30% from baseline to week 48. The percentage of participants is annotated above each bar, calculated with the use of Rubin's rules by combining the percentages of participants who met the thresholds in imputed datasets. *The model-based estimates and 95% CIs from a mixed model repeated measures analysis for the efficacy estimand are shown on the right, denoted by 48.

The mechanical response of vinculin Vinculin buffers force via dynamic domain unfolding/refolding under physiological load and lacks a stable head-tail lock.

Vinculin is a simple adapter protein right? Wrong!

Thatโ€™s been the prevailing view for the 46 years since it was discovered.

Here we provide a new paradigm and show that vinculin is a complex mechanosensor itself, containing 6 binary switch domains.

"Drink more water!" It's the easiest health advice around. Tired? Headache? Trying to be like Tom Brady? Just drink more water. But as a nephrologist, I get asked all the time: How much is the right amount? And the truth is... we don't really know. ๐Ÿงต

Kaplan Meier curve showing the cumulative incidence of type 2 diabetes in people given tirzepatide vs placebo

This month, a phase 3 trial of tirzepatide (a GLP-1 drug) found that it reduced the chances of developing type 2 diabetes by around 90% (!), among people with obesity and pre-diabetes.

That's a reduction if I ever saw one.
