Genome-wide…analysis implicates miRNA dysregulation in #ASD http://www.nature.com/neuro/journal/v19/n11/full/nn.4373.html 58 diff. expr. miRNAs incl 17 strongly down in cases

The miRNA expression profiles were very similar between the frontal and temporal cortex, but were distinct in the cerebellum
(Supplementary Fig. 2a–f), consistent with previous observations for mRNAs11, 12. We therefore combined 95 covariate-matched samples (47 samples from 28 ASD cases and 48 samples from 28 controls;
Supplementary Fig. 1c and Supplementary Table 1) from the FC and TC for differential gene expression (DGE) analysis, comparing ASD and CTL using a linear mixed-effects regression framework to control for potential confounders (Online Methods). We identified 58 miRNAs showing significant (false discovery rate (FDR) < 0.05) expression changes between ASD and CTL: 17 were downregulated and 41 were upregulated in ASD cortex (Fig. 1b and Supplementary Table 2). The fold changes for the differentially expressed miRNAs were highly concordant between the FC and TC (Pearson correlation coefficient R = 0.96, P < 2.2 × 10−16; Fig. 1c).

We still don’t really know how bicycles work

We still don’t really know how #bicycles work
http://www.NewStatesman.com/science/2013/08/we-still-don%E2%80%99t-really-know-how-bicycles-work Still rides upright with special wheels cancelling gyroscopic effect

QT:{{”
“The most definitive analysis came exactly a century later. It involved an experimental bicycle that had all its gyroscopic effects cancelled out by a system of counter-rotating wheels. The effort of building such a strange contraption was worth it: the resulting paper was published the prestigious journal Science.
The publication plunged bicycle dynamics back into chaos. It turns out that taking into account the angles of the headset and the forks, the distribution of weight and the handlebar turn, the gyroscopic effects are not enough to keep a bike upright after all. What does? We simply don’t know. Forget mysterious dark matter and the inexplicable accelerating expansion of the universe; the bicycle represents a far more embarrassing hole in the accomplishments of physics.”

World War Three, by Mistake – The New Yorker

“On June 3, 1980, at about two-thirty in the morning, computers at the National Military Command Center, beneath the Pentagon, at the headquarters of the North American Air Defense Command (NORAD), deep within Cheyenne Mountain, Colorado, and at Site R, the Pentagon’s alternate command post center hidden inside Raven Rock Mountain, Pennsylvania, issued an urgent warning: the Soviet Union had just launched a nuclear attack on the United States. The Soviets had recently invaded Afghanistan, and the animosity between the two superpowers was greater than at any other time since the Cuban Missile Crisis.

U.S. Air Force ballistic-missile crews removed their launch keys from the safes, bomber crews ran to their planes, fighter planes took off to search the skies, and the Federal Aviation Administration prepared to order every airborne commercial airliner to land.”

Can You Tell if These Objects Are Real or Rendered?

Can You Tell if These…Are…Rendered?
https://www.Wired.com/2016/12/skrekkogle-still-life/ @Skrekkogle makes the real appear simulated. Implications for photo evidence

QT:{{”
“The Norwegian design studio Skrekkogle played this game with Still File, a series of photos that look like renderings but aren’t. Instead of manipulating pixels on a screen, studio founders Lars Marcus Vedeler and Theo Zamudio-Tveterås created and photographed sets that look like scenes made with 3-D rendering software. “It’s a weirdly elaborate process,” Vedeler says.

In particularly cool photo, they 3-D printed three wildly distorted teapots, gave them a flat finish, and glued them to the background before photographing them as a surrealist scene. In another, they placed a marble, a plastic cone, and a wood-lined cube atop checkered paper lacquered with acrylic. The camera’s flash reflected the checkerboard pattern onto the objects, creating a false sense of depth.”

You’re an Adult. Your Brain, Not So Much.

Your an adult. Your brain, not so much by @CarlZimmer
http://www.nytimes.com/2016/12/21/science/youre-an-adult-your-brain-not-so-much.html Non-obvious ethical implications of developmental neuroscience

QT:{{”
“The human brain reaches its adult volume by age 10, but the neurons that make it up continue to change for years after that. The connections between neighboring neurons get pruned back, as new links emerge between more widely separated areas of the brain.

Eventually this reshaping slows, a sign that the brain is maturing. But it happens at different rates in different parts of the brain.

The pruning in the occipital lobe, at the back of the brain, tapers off by age 20. In the frontal lobe, in the front of the brain, new links are still forming at age 30, if not beyond.

“It challenges the notion of what ‘done’ really means,” Dr. Somerville said.

As the anatomy of the brain changes, its activity changes as well. In a child’s brain, neighboring regions tend to work together. By adulthood, distant regions start acting in concert. Neuroscientists have speculated that this long-distance harmony lets the adult brain work more efficiently and process more information.”

Quotes from the book I particularly liked:

QT:{{”

In his youth Albert Einstein spent a year loafing aimlessly. You don’t get anywhere by not wasting time on something, unfortunately, that the parents of teenagers tend frequently to forget. He was in Pavia.

QT:{{”

The sun bends space around itself, and Earth does not turn around it because of a mysterious force but because it is racing directly in a space that inclines, like a marble that rolls in a funnel. There are no mysterious forces generated at the center of the funnel; it is the curved nature of the walls that causes the marble to roll. Planets circle around the sun, and things fall, because space curves.

The difference between past and future exists only when there is heat. …

Boltzmann’s idea is subtle and brings into play the idea of
probability. Heat does not move from hot things to cold things due to an absolute law: it does so only with a large degree of probability. The reason for this is that it is statistically more probable that a quickly moving atom of the hot substance collides with a cold one and leaves it a little of its energy, rather than vice versa. Energy is conserved in the collisions but tends to get distributed in more or less equal parts when there are many collisions. In this way the temperature of objects in contact with each other tends to equalize. It is not impossible for a hot body to become hotter through contact with a colder one: it is just extremely improbable.

“Next-generation sequencing has been — and still is — the
technological engine of ENCODE. But looking ahead, researchers might be able to roll out high-resolution live-cell imaging on a large scale to watch the state of the genome change in real time using specific markers. This technology could be disruptive. “If we had a better microscope, we wouldn’t be sequencing anymore,” says

Quark – Wikipedia

https://en.wikipedia.org/wiki/Quark

QT:{{"
For some time, Gell-Mann was undecided on an actual spelling for the term he intended to coin, until he found the word quark in James Joyce’s book Finnegans Wake:

–Three quarks for Muster Mark!
Sure he hasn’t got much of a bark
And sure any he has it’s all beside the mark.

— James Joyce, Finnegans Wake[49]
