Obesity both lowers and increases dementia risk

Obesity both lowers and increases dementia risk

Obese ‘have lower dementia risk

Interpretation
Being underweight in middle age and old age carries an increased risk of dementia over two decades. Our results contradict the hypothesis that obesity in middle age could increase the risk of dementia in old age. The reasons for and public health consequences of these findings need further investigation.

And wait for it:

Midlife overweight and obesity increase late-life dementia risk

Conclusions: Both overweight and obesity at midlife independently increase the risk of dementia, AD, and VaD. Genetic and early-life environmental factors may contribute to the midlife high adiposity–dementia association.

How we make ourselves stupid, idiocracy in action

How we make ourselves stupid, idiocracy in action

Now that due to the AGW scandal the diverse self reviewing peer networks have been proven to exist there is absolutely no reason to assume they don’t exist in other branches of science.

After all they are governed by the same laws of need to publicize, character traits needed to become a top dog and just plain human nature coupled with the downgrading of educational norms.

Since the 1960’s education became a mass product, and logically it had to adapt to the lowest common denominator. Having 90% fail their grades just isn’t a good advertisement for your education centers. So over the decades with each new assessment levels to make the grade got realigned with the average.

The result after all the generations of mediocre students which are the norm setting the norm the stakes against a true scholar making it are minimal outclassed by the majority clawing their way up.

It’s nice, high moral ideas of the right for education for all, but all it does is just making everyone just as incompetent as the the majority.

If einstein or bohr nowadays applied they’d never ever even got close to publication. To name a few. Good luck science, you’ll need it

HERETICAL THOUGHTS ABOUT SCIENCE AND SOCIETY

HERETICAL THOUGHTS ABOUT SCIENCE AND SOCIETY

By Freeman Dyson

The main subject of this piece is the problem of climate change. This is a contentious subject, involving politics and economics as well as science. The science is inextricably mixed up with politics. Everyone agrees that the climate is changing, but there are violently diverging opinions about the causes of change, about the consequences of change, and about possible remedies. I am promoting a heretical opinion, the first of three heresies that I will discuss in this piece.

My first heresy says that all the fuss about global warming is grossly exaggerated. Here I am opposing the holy brotherhood of climate model experts and the crowd of deluded citizens who believe the numbers predicted by the computer models. Of course, they say, I have no degree in meteorology and I am therefore not qualified to speak. But I have studied the climate models and I know what they can do. The models solve the equations of fluid dynamics, and they do a very good job of describing the fluid motions of the atmosphere and the oceans. They do a very poor job of describing the clouds, the dust, the chemistry and the biology of fields and farms and forests. They do not begin to describe the real world that we live in. The real world is muddy and messy and full of things that we do not yet understand. It is much easier for a scientist to sit in an air-conditioned building and run computer models, than to put on winter clothes and measure what is really happening outside in the swamps and the clouds. That is why the climate model experts end up believing their own models.

There is no doubt that parts of the world are getting warmer, but the warming is not global. I am not saying that the warming does not cause problems. Obviously it does. Obviously we should be trying to understand it better. I am saying that the problems are grossly exaggerated. They take away money and attention from other problems that are more urgent and more important, such as poverty and infectious disease and public education and public health, and the preservation of living creatures on land and in the oceans, not to mention easy problems such as the timely construction of adequate dikes around the city of New Orleans.

Bee Deaths Mystery Solved? (hint: Yes, it was environmentalist hysteria as usual)

Bee Deaths Mystery Solved? (hint: Yes, it was environmentalist hysteria as usual)

Although public opinion has coalesced around the belief that the bee death mystery is settled, the vast majority of scientists who study bees for a living disagree—vehemently.

How could a “Harvard study” and a sizable slice of the nation’s press get this story so wrong?.

The buzz that followed the publication of Lu’s latest study is a classic example of how dicey science can combine with sloppy reporting to create a ‘false narrative’—a storyline with a strong bias that is compelling, but wrong. It’s how simplistic ideas get rooted in the public consciousness. And it’s how ideology-driven science threatens to wreak public policy havoc.

Bees are important to our food supply. They help pollinate roughly one-third of crop species in the US, including many fruits, vegetables, nuts and livestock feed such as alfalfa and clover. That’s why the mystery of CCD is so troubling.

One of the central problems with Lu’s central conclusion—and much of the reporting—is that despite the colony problems that erupted in 2006, the global bee population has remained remarkably stable since the widespread adoption of neonics in the late 1990s. The United Nations reports that the number of hives has actually risen over the past 15 years, to more than 80 million colonies, a record, as neonics usage has soared.

Country by country statistics are even more revealing. Beehives are up over the past two decades in Europe, where advocacy campaigns against neonics prompted the EU to impose a two-year moratorium beginning this year on the use of three neonics.

The 10 stuff-ups we all make when interpreting research


UNDERSTANDING RESEARCH: What do we actually mean by research and how does it help inform our understanding of things? Understanding what’s being said in any new research can be challenging and there are some common mistakes that people make.

Have you ever tried to interpret some new research to work out what the study means in the grand scheme of things?

Well maybe you’re smart and didn’t make any mistakes – but more likely you’re like most humans and accidentally made one of these 10 stuff ups.
