By the way, if you’re reading this Tumblr post, you’re looking at a free portal into Newsweek.com, which normally has a paywall. Enjoy!
Because your nostrils split their workload. Throughout the day, they each take breaks in a process of alternating congestion and decongestion called the nasal cycle.
At a given moment, if you’re breathing through your nose, the lion’s share of the air is going in and out of one nostril, with a much smaller amount passing through the other. Every few hours, your autonomic nervous system, which takes care of your heart rate, digestion and other things you don’t consciously control, switches things up and your other nostril does all the heavy lifting for a little while.
The opening and closing of the two passages is done by swelling and deflating erectile tissue - the same stuff that’s at work when your reproductive organs are aroused - up in your nose. The nasal cycle is going on all the time, but when you’re sick and really congested, the extra mucous often makes the nostril that’s on break feel much more backed up.
There are at least two good reasons why nasal cycling happens: And Mental Floss explains why…)

THIS IS NOT A TEST!!! REPEAT THE FUTURE IS NOW!!!
Ever since NASA retired its space shuttle program in 2011, the only way to get up to the International Space Station is on a Russian Soyuz. That’s why the six humans currently orbiting in space—including two Americans and three Russians—might be paying attention to what’s happening on earth two hundred miles below.
As tensions run high between the U.S. and Russia over the situation in Ukraine, geopolitics may find its way into space again. Over at the blog Looking Up, Duncan Geere has written an excellent piece laying out possible astro-political scenarios in space.
While all-out war remains unlikely, astronauts could become a point of leverage for Vladimir Putin in a larger conflict. “It’s not inconceivable that the International Space Station may play some part in this — either by denying the U.S. the use of Soyuz, or simply by charging exorbitant amounts for it,” Geere writes.
With ISS trips planned years in advance, there are only ten Soyuz launches scheduled from now until 2016. In addition, NASA has to be granted special exemptions to the Iran North Korea Syria Nonproliferation Act, which normally prohibits the U.S. from buying space-related goods and services from Russia while it’s selling nuclear technology to Iran. NASA’s exemption expires in 2016, and, if the relationship between the U.S. and Russia worsens, this could become a tougher sell.
Washington Post: The SAT college admission test will no longer require a timed essay, will dwell less on fancy vocabulary and will return to the familiar 1600-point scoring scale in a major overhaul intended to open doors to higher education for students who are now shut out.
A piece of a very big puzzle we’ve solved on the cover of the NEW NEWSWEEK, out tomorrow. #longliveprint
"The big companies (Google, Netflix, Apple) recognize those that use a lot of bandwidth should contribute to that," says Verizon CEO Lowell McAdam. (via Verizon CEO: We see a Netflix deal ahead)
LAST year 264 people died in road crashes in Sweden, a record low. Although the number of cars in circulation and the number of miles driven have both doubled since 1970, the number of road deaths has fallen by four-fifths during the same period.
With only three of every 100,000 Swedes dying on the roads each year, compared with 5.5 per 100,000 across the European Union, 11.4 in America and 40 in the Dominican Republic, which has the world’s deadliest traffic, Sweden’s roads have become the world’s safest. Other places such as New York City are now trying to copy its success.
How has Sweden done it? Since reaching a peak in road deaths in the 1970s, rich countries have become much better at reducing the number of traffic accidents. (Poor countries, by contrast, have seen an increasing death toll, as car sales have accelerated.) In 1997 the Swedish parliament wrote into law a “Vision Zero” plan, promising to eliminate road fatalities and injuries altogether.
"We simply do not accept any deaths or injuries on our roads," says Hans Berg of the national transport agency. Swedes believe—and are now proving—that they can have mobility and safety at the same time. Planning has played the biggest part in reducing accidents. Roads in Sweden are built with safety prioritised over speed or convenience.
Low urban speed-limits, pedestrian zones and barriers that separate cars from bikes and oncoming traffic have helped. Building 1,500 kilometres (900 miles) of “2 1” roads—where each lane of traffic takes turns to use a middle lane for overtaking—is reckoned to have saved around 145 lives over the first decade of Vision Zero.
And 12,600 safer crossings, including pedestrian bridges and zebra-stripes flanked by flashing lights and protected with speed-bumps, are estimated to have halved the number of pedestrian deaths over the past five years. Strict policing has also helped: now less than 0.25% of drivers tested are over the alcohol limit. Road deaths of children under seven have plummeted—in 2012 only one was killed, compared with 58 in 1970. The Economist explains:Why Sweden has so few road deaths | The Economist)
