NASA scientists have reported that they’ve successfully tested an engine called the electromagnetic propulsion drive, or the EM Drive, in a vacuum that replicates space. The EM Drive experimental system could take humans to Mars in just 70 days without the need for rocket fuel, and it’s no exaggeration to say that this could change everything.
But before we get too excited (who are we kidding, we’re already freaking out), it’s important to note that these results haven’t been replicated or verified by peer review, so there’s a chance there’s been some kind of error. But so far, despite a thorough attempt to poke holes in the results, the engine seems to hold up.
“Be waiting out front of the HAB, Watney, we’re not fucking waiting for you to get dressed. Places to be.”
Guys. Guys. I’ve been following this story for a while now and you don’t get it. Some guy made this and was like “well hi I made a thing and it shouldn’t go but it goes.”
And the science community was like okay that… there’s no way that works.
Then they tested it theoretically and it worked.
Then NASA was like okay but technically this breaks one of Newton’s laws so even if it theoretically goes it won’t like, actually go. So they built it and tested it more and it works.
So what we have now is the scientific community slowly cautiously freaking out because this GODDAMN EM DRIVE breaks the RULES OF PHYSICS but every time we test it, it FUCKING WORKS.
How cool is this????
Every time we’ve found something “broken” that functions, it means something is wrong with our understanding of reality. The next step is to figure out what, figure out what’s true, and open up a plethora of new scientific discoveries.
Scientists hope to hugely reduce the cost of wind energy by removing the blades from wind farms, instead taking advantage of a special phenomenon to cause the turbines to violently shake.
Vortex, a startup from Spain, has developed the tall sticks known as Bladeless — white poles jutting out of the ground, that are built so that they can oscillate. They do so as a result of the way that the wind is whipped up around them, using a phenomenon that architects avoid happening to buildings and encouraging it so that the sticks shake.
They do so using vortices, which is where the company gets its name from. The bladeless turbines use special magnets to ensure that the turbines are optimised to shake the most they can, whatever speed the wind is travelling at.
As the sticks vibrate, that movement is converted into electricity by an alternator.

These also look like they would cause fewer problems for birds and bats.
This is really cool.
They leave off the important note that when the wind rises, each pole makes a sound like a hundred vuvuzelas roaring at once. In the post-apocalyptic world of the future, villagers will speak in hushed tones about the Roaring Plains, and caution adventurous travelers to stay well away.
I appreciate how they essentially invented very useful yet alien-looking screaming pillars. Science continues to make some suspiciously sci-fi shit.
The development of antimalarial drugs is fascinating – it is often driven by war and conquest. When human beings got busy trying to kill each other (during the era of colonial expansion, WWII, the Vietnam War), they often found themselves face to face with an even deadlier foe.
I have not had time to make my own blog post today about The Nobel Prize in Physiology or Medicine 2015, and there are already many out there circulating. Among the best I saw, this one published by Adam Cole in his blog, is focused in Tu Youyou (congrats) and her discovery of Artemisinin to fight malaria.
Congratulations also to the other half of the prize:
According to UNICEF, 663 million people worldwide do not have access to clean drinking water. The book’s technology can successfully turn even diluted sewage into filtered water that’s comparable to the tap water in America.
How it works: Tear out a page, slide it into the filter box, pour in the contaminated water, and what comes out is safe to drink.
One book can provide someone with clean water for up to four years.
Each book costs pennies to produce, but funding is desperately needed to help bring it to the market.
We finally have a firm answer to one of the biggest mysteries of Mars. Not only did the Red Planet have water in the past, but it has it right now, flowing in a briny mix that keeps it from freezing. This confirms decades of observations.
In an article published in Nature Geoscience, a team lead by Lujendra Ojha of the Georgia Institute of Technology confirms that seasonal flows in mountainous regions of the planet correspond with the presence of briny water. The seasonal flows were first noticed in 2010, with water the strongest suspect. Spectral observations of season data from the Mars Reconnaissance Orbiter indicate the presence of hydrated salts on the surface, or water mixing with a thick brine of salts.
