At TFL, we're making journeys safer for everyone, and that includes improving safety on London's roads.

That's why we and London boroughs are lowering more speed limits to 20 miles per hour,

Such TFL improvement plan to the Mayor of London and TFL every journey matters.

This is CBSI in the world. I'm John Batcher, Bob Zimmerman. He keeps the website behind the black.

Bob, a very good evening to you. What is Retraction Watch? Thank you.

John Retraction Watch is a website that was founded on the same time I founded behind

papers that are retracted, peer review papers that are retracted by scientists or by journals,

because of bad work, dishonesty, fraud, mistakes, whatever. They just track every paper they

get retracted. They published an op-ed recently in the Guardian in Britain where they

each year since the beginning of this century in 2000 has increased yearly on astonishing

13,750 percent. They had 40 retractions worldwide in 2000, and in 22, they had 5,500.

Following the science, what do you call it? Scientific research world, as I do. There's no doubt

that the number of errors, dishonesty, fraud, mistakes in science work has been increasing

exponentially in the last quarter century to a point where it's now you cannot, you cannot,

and you must not take on faith any scientific paper you read even if it's peer-reviewed.

You want to do that, but you should not do that anymore. It should be questioned every

sense. Now, of course, everything should always be questioned, but in the past, you could have

faith that the science editors at journals and peer-review were doing the proper due diligence,
