The Delta variant: updates from the new @PHE_Uk report assets.publishing.service.gov.uk/government/upl…
1st dose vaccine (either AZ or Pfizer) quite protective vs hospitalization
Fully vaxxed vs unvaxxed:
Infections 7.7% vs 67%
Hospitalizations 8% vs 48%
Delta's secondary attack rate is coming down some in the latest dataset. Its enhanced transmission over alpha appears to be more in the 40-60% range
Reinfections by sequencing data: 311/1260 were Delta
This 71-page report is rich. And that 60% of infections are getting sequenced (91% are Delta) is quite impressive.
It makes the output from CDC and the genomic surveillance in the US particularly weak
Here is the latest @CDCgov variant report. It is from May 22 and it's frankly pathetic when you compare it to @PHE_UK, both with respect to it being out of date and the lack of sequencing in the US covid.cdc.gov/covid-data-tra…
Contrast today's @PHE_UK report from genome sequencing (60% of cases) up to 4 days ago -- >60,000 Delta cases with vaccination status and outcomes
For medical information, general AI frontier models (Google, OpenAI, Anthropic) outperformed specialized @EvidenceOpen and @UpToDate as assessed by 12 US clinicians, randomized and blinded to which model and extensive testing/benchmarks. This was not anticipated. @NatureMedicine nature.com/articles/s4159…
If you're interested in how AI grew up over the past 15 years, and where it's headed, this new book tells the story in a riveting, page-turner way. In the new Ground Truths with @scmallaby
In 2010, when @GoogleDeepMind was formed, well before deep learning was taking hold, @demishassabis predicted AGI by 2030 and called out the use of agents
@GoogleDeepMind @demishassabis This is pretty striking

Physical activity and the reduction of all-cause mortality, from 2 very large prospective cohorts 1. The relationship is non-linear, suggesting a threshold effect for many types of exercise as seen below
2. Engaging in > 1 type of physical activity was generally correlated with better outcomes compared with 1 type (T1,2,3)
People age 70+ should not be taking aspirin at any dose for prevention. Results of randomized trials show higher risk of all-cause mortality, major bleeding events and deaths from cancer. p 153, SUPER AGERS book
President Trump takes 325 mg aspirin/day. The randomized trials tested 75-81 mg/day. His doctors recommended low-dose aspirin for heart event prevention. That recommendation is ill-founded based upon best evidence in older individuals. nejm.org/doi/full/10.10… academic.oup.com/eurheartj/arti…
As I wrote in SUPER AGERS, the immune system is the key to modulating our aging process and the opportunity to extend healthspan. Today @NatureAging 7 new articles, summarized here, that reinforce its central role nature.com/articles/s4358…
