On October 3 1849, the famed American horror and mystery author Edgar Allan Poe was found in a complete state of delirium – incoherent, dishevelled and wearing a stranger’s clothes. Four days later, he died in a hospital. His final words were “Lord, help my poor soul”.

About 74,000 years ago on the island of Sumatra, Indonesia, the largest volcanic event over the last two million years, 5,000 times larger than the Mount St. Helen's eruption in the 1980s, ushered in a worldwide "volcanic winter" that lasted up to ten years followed by a 1,000 year-long cooling of the Earth's surface.

While how close humanity got to extinction is unknown, surviving Homo sapiens in Africa were said to have survived by developing new strategies that eventually enabled them to re-expand and populate Asia 60,000 years ago in a single, rapid wave along the Indian Ocean coastline.
In recent years the U.S. Centers for Disease Control and Prevention have manufactured a lot of concerns they then ask Congress for money to help solve - Zika, Prediabetes, vaping in kids are all examples of where they hyped concern or even defy the international consensus to worry the American public.

Hopefully there is one thing they can feel comfortable eliminating - telling adults to get diphtheria and tetanus booster shots every 10 years. A new study found that if adults were fully vaccinated as kids, booster shots are just increasing health case costs while subsidizing manufacturers.
What do you conclude when different foods are claimed to be eaten on surveys by people who have one type of stroke but not another?

Not much. But it will still be a food frequency questionnaire epidemiology paper, the bane of public trust in science. What about confounders? Were people on medication, like statins?  The people who had strokes were 59-60 when they enrolled in the survey, so what about their lifestyle choices prior to that?

In an age of deepfakes and alternative facts, it can be tricky getting at the truth. But persuading others – or even yourself – what is true is not a challenge unique to the modern era. Even the ancient Greeks had to confront different realities.

Edgar Allan Poe, The author, poet, editor, and literary critic, died in 1849 at age 40 in Maryland. He was chronically depressed, he had even tried to commit suicide using laudanum a year before his death.

But when he went to the hospital for the last time, having been found delirious and wearing a stranger's clothes, he hadn't been committing suicide, according to a heuristic look at his writing.
A new paper claims that the Mediterranean diet may increase "longevity" and it created its mystical conclusion using the favored magic wand of food studies, epidemiological correlation, sprinkled with biological speculation.

You may be old enough to remember other claims using similar kernels of scientific truth that became popular diet fads; cigarettes, grapefruit, cabbage. the Adkins diet, Paleo. 
Tomorrow morning the Cornell arXiv will publish the preprint of a long scientific article, the result of 4.5 months of painstaking work by yours truly. So I thought I would give you a preview of its contents. Of course, it will take more than a single post to do a good job - I guess I can describe the generalities here, and leave it to another time the plunging into technical details that may only be interesting to insiders.

First of all, what experiment are we talking about? It is called "MUonE", and it aims at measuring with the utmost precision the rate at which muons scatter elastically off electrons, as a function of the transferred energy of the scattering reaction. 
Merge is a controversial belief by some that human language faculty arose in humans through a single gene mutation, rather the evolving gradually.

This human burst of genetic exceptionalism is embraced by some linguists, such as Noam Chomsky, but the science community has doubts. The basis for Merge is that humans are genetically equipped with a unique cognitive capacity that specifically allows us to implement computations over hierarchically structured symbolic representations.
A new paper says scientists can make their work more appealing to the public by making it more personal. I learned of it through a paid university PIO but few scientists will see the irony in that.

I certainly agree with the point. I have been part of two communities, science and the military, that in defiance of public perception are filled with hilarious people who have great stories. But when the recorder comes on, it's often like talking to someone in marketing who hasn't been cleared for media by their boss. They clam up or give canned answers.
