In defence of the black cab, if there is any sort of surge pricing in Uber, the black cab is typically cheaper if you can find one. Apps like Gett solve the ‘not knowing the price upfront’ problem, prebooking and hailing.
I think black cabs are a lot easier if you have lots of luggage, or especially if you have a pram/stroller. Rearward facing seats are safer for kids and cabs seat six comfortably. And the final big advantage: in London, black cabs get to use the bus lanes which can save inordinate amounts of time at rush hour.
I still use Uber all the time but I just thought I would add some balance!
AS01-adjuvanted shingles (herpes zoster) vaccination is associated with a lower risk of dementia, but the underlying mechanisms are unclear. In propensity-score matched cohort studies with 436,788 individuals, both the AS01-adjuvanted shingles and respiratory syncytial virus (RSV) vaccines, individually or combined, were associated with reduced 18-month risk of dementia. No difference was observed between the two AS01-adjuvanted vaccines, suggesting that the AS01 adjuvant itself plays a direct role in lowering dementia risk.
This is a really interesting idea and the unit economics are great. However when I researched this (or rather Gemini 2.5 Pro researched this) the problem appears that Haber-Bosch produces ammonia, whereas Birkeland-Eyde produces nitrate, which then needs to be converted in nitric acid. Getting from nitric acid to ammonium nitrate (which dominates the fertiliser market) needs ammonia from somewhere, which destroys the economics.
However calcium nitrate, potassium nitrate production via B-E looks really interesting.
I may be being dense, and I realise this is a meta analysis, but the abstract doesn’t explain how much fibre one needs to eat to reduce all-cause mortality by the amount they claim?
Thanks. I would still be curious to know how the strength of an artificial magnetic field at a range of say 10 km compares to the order of magnitude of local variations they are talking about in the earth’s magnetic field.
Agree. My mother had a very serious form of cancer (she’s luckily responded well to treatment) but she was overwhelmed by con men promising hope. Adding legitimate research makes this mix less toxic, not more
