Published Drug Research Accents the Po$titive

Published Drug Research Accents the Po$titive

Scientific Method be damned, medical journals have an economic incentive for publishing papers with postive outcomes. When a drug study shows positive outcomes, pharmaceutical companies buy reprints of it in bulk to distribute it to prescribers.

Those purchases can add up to over $2 million. For journals like The Lancet ($40 annual revenue) and NEJM ($100 million/yr.), that’s huge. 41 percent of The Lancet’s 2021 income came from reprints. When it comes to drug studies, Big Phama’s thumb is firmly on the scale.

Mesmerism

July 8, 2021

“Franz Anton Mesmer, a charismatic physician from Vienna, Austria, began ‘healing’ people in Paris using an alternative therapeutic practice he called ‘animal magnetism’ …..

“Mesmer claimed an invisible magnetic fluid was the life force that connected all things, and that he had the power to regulate it to restore health in his patients. He was a celebrity figure until Louis XVI, the last king of France, commissioned a group of leading scientists to investigate Mesmer’s methods in 1784.”

Found: Hidden Water on Mars

Found: Hidden Water on Mars

“Vast amounts of ancient Martian water may have been buried beneath its surface instead of escaping into space, scientists report in the journal Science. The findings, published Tuesday, may help untangle a clash of theories seeking to explain the disappearance of Mars’ water, a resource that was abundant on the planet’s surface billions of years ago.

Through modeling and data from Mars probes, rovers, and meteorites, researchers at the California Institute of Technology found that a broad range — between 30 to 99 percent — of the Red Planet’s earliest amounts of water could have vanished from the surface through a geological process called crustal hydration, where water was locked away in the rocks of Mars.”

— “Mars might be hiding most of its old water underground, scientists say,” Joey Roulette, The Verge

The Moon Is Awash In Water

The Moon Is Awash In Water

Two new studies indocate that there are “cold traps” on the moon full of water. NASA spied on Luna from a high-flying jet named SOFIA (Stratospheric Observatory for Infrared Astronomy) and found the unique signature of water all over the place on sunlit portions of the moon. A secord study finds that frozen water could be hiding in lunar shadows on 15,444 square miles of the moon’s real estate. Astronauts are probably planning lakeside chateaus as you read this.
