Pic basically unrelated, but required to post so maybe I’m in the wrong place. If there’s a better place for this lmk. Fediverse is hard to suss for locations.

Basically what I want to know is what would happen if you strapped your head into something that caused medium-intensity vibration, and just left it there indefinitely (assuming you were, for the sake of this question, functionally immortal as far as age and nutrition, but not physical damage)

I’m not talking industrial vibration, more like something we would consider safe, like an intimate toy intensity (but not a hitachi magic wand - normal people intensity), or a vibrating “weight loss plate”, or even maybe like the roughness from a long drive, assuming your head is strapped on to get the full force of it rather than your neck muscles nihilism.

I know there’s a fluid cushion around the brain that prevents impact damage to an extent, but vibration isn’t really the same thing, so would your cells just sort of rupture over time and bleed out or is there enough padding to absorb all of it with no consequence?

A scientific paper that raised concerns about the safety of the abortion pill mifepristone was retracted by its publisher this week. The study was cited three times by a federal judge who ruled against mifepristone last spring. That case, which could limit access to mifepristone throughout the country, will soon be heard in the Supreme Court.

The now retracted study used Medicaid claims data to track E.R. visits by patients in the month after having an abortion. The study found a much higher rate of complications than similar studies that have examined abortion safety.

Sage, the publisher of the journal, retracted the study on Monday along with two other papers, explaining in a statement that "expert reviewers found that the studies demonstrate a lack of scientific rigor that invalidates or renders unreliable the authors' conclusions."

It also noted that most of the authors on the paper worked for the Charlotte Lozier Institute, the research arm of anti-abortion lobbying group Susan B. Anthony Pro-Life America, and that one of the original peer reviewers had also worked for the Lozier Institute.

Mary Ziegler, a law professor and expert on the legal history of abortion at U.C. Davis: "We've already seen, when it comes to abortion, that the court has a propensity to look at the views of experts that support the results it wants," she says. The decision that overturned Roe v. Wade is an example, she says. "The majority [opinion] relied pretty much exclusively on scholars with some ties to pro-life activism and didn't really cite anybody else even or really even acknowledge that there was a majority scholarly position or even that there was meaningful disagreement on the subject."

The new world record has been set at the UK-based JET laboratory.

The result came from the lab's final experiment after more than 40 years of fusion research.

The experiments produced 69 megajoules of energy over five seconds. That is only enough energy for four to five hot baths - so not a lot.

It is clear we are still a long way off from nuclear fusion power plants, but with every experiment it is bringing us one step closer.

“Imagine the Earth almost completely frozen over,” said the study’s lead author, ARC Future Fellow Dr Adriana Dutkiewicz. “That’s just what happened about 700 million years ago; the planet was blanketed in ice from poles to equator and temperatures plunged. However, just what caused this has been an open question.

“We now think we have cracked the mystery: historically low volcanic carbon dioxide emissions, aided by weathering of a large pile of volcanic rocks in what is now Canada; a process that absorbs atmospheric carbon dioxide.”

In the latest study by Prof. Dr. Leonid Ionov, Professor of Biofabrication, and his team at the University of Bayreuth, various types of hydrogels were extensively tested for the 3D printing of tissues. A hydrogel is a water-retaining and also water-insoluble polymer. In addition, the cell containing–hydrogels, also known as bioink, are combined with fibers to create a composite material.

This is achieved by using 3D (bio) printing with an integrated touch-spinning process. Touch spinning is a scalable process for producing fibers from a polymer solution or melt. The Bayreuth scientists have now combined 3D (bio) printing technology with touch-spinning technology in a single device for the first time.

"The insights gained in this study are of great importance for the production of tissues and in particular tissues with fibrous structures and uniaxial alignment of cells such as connective and muscle tissue," explains Prof. Dr. Ionov.

Temperature is a measure of the microscopic-scale motions of atoms and molecules that comprise matter

It turns out that the appendix appears to have two related functions. The first function is supporting the immune system. The appendix has a high concentration of immune tissue, so it's acting to help the immune system fight any bad things in the gut.

The second function that it serves is what we refer to as the safe house. So this was a hypothesis that was put forward by a team from Duke University in 2007. And they argued that the appendix may serve as a safe reservoir for the beneficial gut bacteria that we have.
