Scientific publishing is a competitive environment, under heavy scrutiny from reviewers, editor and peers. Over the years, some studies get retracted, and that’s not a bad thing in itself; a study can be retracted because more data is available, disproving it, or because a human or technical error snuck in – that’s perfectly understandable, and the review and correction process
Veteran astronaut Scott Kelly launched in March, 2015 aboard a Soyuz rocket for a record breaking one-year stay at the ISS. Instead of three to six months, Kelly along with his Russian colleague, Mikhail Korniyenko, will spend 12 months so scientists can assess how his body responds to the stress. For instance, we know that living in microgravity atrophies muscles and deteriorates vision. Kelly isn’t too worried, though. When not busy operating the International Space Station, Kelly is engaged in one of the most pleasing hobbies (for those of us living back on Earth, that is): space photography. Here are just a couple of his most amazing shots shared by Kelly on his facebook or twitter account. He updates these very frequently, even a couple of times a day, so be sure to tune in for some more gems.
The Øresund strait separates the Danish island Zealand from the southern Swedish province of Scania. Its width is 4 kilometres (2.5 mi) at the narrowest point between Kronborg Castle at Helsingør in Denmark – but this couldn’t stop these Scandinavic countries. They designed a magnificent bridge that turns into a tunnel… let me explain. The Øresund was designed by the Danish

These little and pretty cottages do a really good job at keeping the cold out – plus they’re friendly with the environment and surprisingly cozy. Many years before going green was a thing, Icelanders were constructing eco-friendly houses without even knowing it. In countries such as Norway, Scotland, Ireland and Greenland turf houses were left to those who couldn’t afford anything
We all have a hobby. Reddit user’s -rico hobby is collecting factory GIFs. You know, the ‘How it’s Made’ kind of GIFs, the one that show how our day to day products are created? I’ve taken some from his list, found some more online, and here they are: Icecream Pretzels (several variations) Pretzels are often made by hand, but if you do them
Symbols and myths tied to our golden star abound, and it’s easy to see why: all life on Earth literally, and figuratively, revolves around the Sun, including us. Setting tales aside, we’ve come to a place in our evolution where we can more directly, and efficiently, harness its power to keep our civilization running. And it’s a lot of energy.
We see this too often – loads and loads of discarded books in storage rooms, on the sidewalk, even in our homes. Abandoned books are a much too common sight, and at least to me, a depressing sight. This inspired San Francisco-based artist Alexis Arnold to embark on a fascinating quest to make something beautiful – crystallized books. “The Crystallized Book series
Recently, we wrote an article about the biggest tree census ever conducted, and the results were pretty grim. Sure, there are some 3 trillion trees on Earth, but the bad news is that there used to be almost twice as many – before humans chipped in. Humanity has cut down 46% of the planet’s trees, and we’re continuing to do
