nice overview of the 3 main space related projects attempting to bring internet access to the world, namely SpaceX+Google micro-satellites network, OneWeb+Virgin Galactic OneWeb and Project Loon by Google. not a lot of technical details though...

Last week NASA and NOAA announced that 2014 topped the list of hottest years ever recorded. Yikes! What's worse, the ten warmest years ever recorded have all occurred since 1998. Yikes again! In the meantime, the ACT is skiing on stones and rocks in Switzerland ^^

Interesting article about theoretical physics theories vs. experimental verification. Can we state that a theory can be so good that its existence supplants the need for data and testing ? If a theory is proved to be untestable experimentally, can we still say that it is a scientific theory ? (not in my opinion)

Awarded videos of fluid motion presented at the APS DVD meeting. Very cool stuff. #0084 is done with the setup I used for my master thesis.

NASA and ESA spacecraft have gathered new information about the basic properties of the comet's nucleus (not 67p) and directly detected the effects on the Martian atmosphere. Dust from the comet impacted Mars and was vaporized high in the atmosphere, producing what was likely an impressive meteor shower. Eight different types of metal ions have been detected, including sodium, magnesium and iron. The satellites will now continue to look for long-term perturbations to Mars' atmosphere.

It's something...

"As you read this, your neurons are firing - that brain activity can now be decoded to reveal the silent words in your head TALKING to yourself used to be a strictly private pastime. That's no longer the case - researchers have eavesdropped on our internal monologue for the first time. The achievement is a step towards helping people who cannot physically speak communicate with the outside world." Or alternatively, a step towards snooping into individuals' privacy.

Alvin, the only deep-diving manned submersible used for science has been upgraded, allowing scientists to explore for the 1st time the depth of the oceans down to 6500m bsl.

"Collider is an arty audiovisual experience that provides a first-person perspective of a particle hurtling through the Large Hadron Collider"... with the use of the Leapmotion sensor and Oculus Rift hmd. Come to my desk if you wanna try it :) (not that fun actually)

A nice article explaining the principle of quantum superposition from the double slits experience. Nothing new here but still interesting to read :)

This is the interesting master project of a good friend from my university, not really related to space though. Replacing the drone's wifi antenna by an Avalanche Victim Detector, it could be a very promising tool to deploy the first avalanche searches.

Using the angular momentum transmitted by an internal flywheel as an impulse, these cubes can move, jump, roll across the ground and climb over and around one another. They stick together using a set of small magnets, smart !

"Could you do this? Could a spinning human slow down the Earth? Theoretically, yes." Let's all put our ice skates on and spin to enjoy a longer daytime !
