I shared this all the way back in 2012, and someone else just reshared it and the notification reminded me of it.  

It's pretty frickin' cool!

Animated gif of IC1396, a nebula in the constellation of Cepheus. It contains the well-known Elephant's Trunk Nebula and is about 2400 ly distant. Illumined by a huge O star (HD 206267), it's one of the largest emission nebulae in the Northern hemisphere.

An emission nebula consists of a cloud of ionized gas. Lower intensity will result in a predominance of red light, as hydrogen has a low energy of ionization. Green and blue will start to emerge as the intensity of the emission rises. The dark portions in the foreground are interstellar dust blocking the light from behind.

From the artist's site, linked below:

Since astronomical objects are too far away, no real parallax can be imaged. Doe to that, I have developed a method to turn my images to various 3D-formats. My work flow is based on scientific data from the object, distance and the source of ionization are usually known. The different types of the nebulae has typical structures, pillar like formations must point to the source of ionization, the radiation pressure forms kind of hollow area, inside of the nebula, around newly born stars, dark nebulae must be at front of the emission ones to show, etc… rest of the missing information is then replaced with an artistic vision.

Why is short-sightedness on the rise?  Too much time indoors!

After studying more than 4,000 children at Sydney primary and secondary schools for three years, they found that children who spent less time outside were at greater risk of developing myopia.

The myopia boom
Short-sightedness is reaching epidemic proportions. Some scientists think they have found a reason why.

It's not uncommon for me to hear the exhortation to not eat processed foods

 Of course, when pressed on the why, most people delve into pseudoscience or end up admitting they're just parroting something they read.

Well here's some science!

The emulsifiers in question are carboxymethycellulose and polysorbate-80; especially in Europe and North America, they are commonly used in processed foods (mayo, ketchup, numerous sauces, ice cream, gluten-free products, fat-free products and many others) and other common products (toothpaste, detergents etc). The study conducted on mice showed that even in low concentrations, these substances drastically affect the gut bacteria which seems to lead to obesity as well as a number of gut-related problems.

Why processed foods make you fat: two common food additives linked to obesity and gut inflammation
A new study suggests that two very common emulsifiers – chemicals that stabilize foods and stop products like mayo from separating – could increase the risk of obesity and irritable bowel syndrome.

Why Fahrenheit is Better than Celsius

Women are weaklings!

The upshot is that the very strongest female athletes are barely above the median of grip strength for men. The top 75th percentile of female athletes are below the bottom 25th percentile of men. Another way to look at it is cumulative distributions. You can tell looking at this that there is overlap between the two sample distributions. How much? Ten percent of women have stronger grips than the bottom five percent of men. The difference in distributions is big enough that the very strongest non-elite athlete female in the whole data set has a weaker grip than most of the men.

Men are stronger than women (on average)
Every now and then there is a debate on who is more “anti-science”, the Left or the Right. I’m not too interested in the details of that, but, a few years ago I expressed my skepticism to Chris Mooney, author of The Republican War on Science, that liberals were somehow reflexively more “pro-science.” I suggested […]
