From PetaPixel:

It looks like not even space photography has managed to escape the pixel war, but in the case of the Russian Federal Space Agency’s Elektro-L weather satellite, we’re not complaining. The video you see above is a time lapse put together from 6 days worth of 121-megapixel images taken every 30 minutes by the satellite. The images themselves are not composites of several either, they are just incredibly detailed photos of the entire planet taken from some 22 thousand miles away.

They’re so detailed, in fact, that the resolution comes out to about 1 kilometer per pixel — or in laymen’s terms: this ain’t no camera phone. To add a little bit of color to the proceedings the images are also taken in 4 rather than just 3 wavelengths, yielding that orange color which is actually infrared imaging of vegetation.

Katrina Gulliver discusses the use of Twitter and ends her article with her Ten Commandments:

1. Put up an avatar. It doesn’t really matter what the picture is, but the “egg picture” (the default avatar for new accounts) makes you look like a spammer.

2. Don’t pick a Twitter name that is difficult to spell or remember.

3. Tweet regularly.

4. Don’t ignore people who tweet at you. Set Twitter to send you an e-mail notification when you get a mention or a private message. If you don’t do that, then check your account frequently.

5. Engage in conversation. Don’t just drop in to post your own update and disappear. Twitter is not a “broadcast-only” mechanism; it’s CB radio.

6. Learn the hashtags for your subject field or topics of interest, and use them.

7. Don’t just make statements. Ask questions.

8. Don’t just post links to news articles. I don’t need you to be my aggregator.

9. Do show your personality. Crack some jokes.

10. Have fun.

As of 1945, that is.

Salon’s Steve Kornacki discusses the effects of the Tea Party on the GOP. It’s written in light of Se. Lugar’s primary defeat:

“Bipartisanship,” Mourdock declared last week, “ought to consist of Democrats coming to the Republican point of view.”

This is as concise a distillation of the Tea Party’s governing vision as you’ll find. It’s not really about moving the GOP to the right; the party is already there, and has been for a while. It’s about reflexively opposing the other party on every issue, resisting compromise at all costs, and exploiting every available legislative tool to stymie the other side. This mindset is already pervasive in the House, and as the Times story shows, it’s now making its way into the Senate.

Kornicki sees the change as moving toward a parliamentary style.

Frank Jacobs discusses world maps that plot population distribution:

Did you know that almost 90% of the world’s population lives in the northern hemisphere? And that half of all Earthlings [1] reside north of 27°N? Or that the average human lives at 24 degrees from the equator – either to its north or south? Bill Rankin did. Or at least he found out, while producing this fascinating diptych of world maps, plotting population distribution on axes of longitude and latitude.

These maps have been floating around the internet for a few years now [2]. Like barnacled ships and whales at sea, they show their age by the virtual symbionts with which they are encrusted.

Or in this case, some rather opinionated comments.

Some commenters find fault with these maps: Exactly what information do they display? It is not population density, so much as population distribution that is shown. From either of these infographics alone, the precise locations of the densely inhabited centres of the world are not readily deducable.

But I side with those who fall for the abstract beauty of these graphs. Divorced from direct geographical (let alone historical and sociological) context, and further divided by longitude and latitude [3], they have an intriguing quality, inviting us to decode them all over again.

The online visualization titled “3.1415926535897932384626…” [two-n.com] by design studio TWO-N represents the first 4,000,000 decimals of the number Pi within a single image.

Each unique digit of Pi corresponds to a specific color, and is rendered as a 1×1 pixel dot. The result is a long, random-looking pixel carpet image. Next to a dedicated slider that allows up/down scrolling through the resulting image, one can also search for the first occurrences of any specific decimal combination.

The movie “Welcome to the Anthropocene” [vimeo.com] developed by global education organization Globaia reveals the start of a new geological era dominated by humans, by visualizing its main infrastructure, such as cities, roads, railways, transmissions lines and underwater cables.

After researchers learned that Swiss farm kids are much less prone to allergies than city kids, they took a look at Amish families in the U.S. the incidence of allergies was even less with them:

The study did not determine why the kids who grew up on farms were less likely to develop asthma and allergies, but other research has pointed to exposure to microbes and contact with cows, in particular, to partially explain the farm effect (see Reuters Health story of May 2, 2012).

Drinking raw cow’s milk also seems to be involved, Holbreich said.

The going theory is this early exposure to the diverse potential allergens and pathogens on a farm trains the immune system to recognize them, but not overreact to the harmless ones.

As for why the Amish kids have even lower allergy and asthma rates than the other farming kids, “that piece of the puzzle we really haven’t explained,” Holbreich told Reuters Health.

He speculated that it could be at least partly a result of the Amish having larger families or spending even more time outside or in barns than people on more modern working farms.

Dr. Corinna Bowser, an allergist in Cherry Hill, New Jersey, said there’s also a possibility that inherited factors could play a role.
