Now a NASA engineer has come up with a new way to fling satellites through space on mere grams of fuel, tens of times as efficiently as today’s best space probe thrusters.

Anyone out there still doing propulsion stuff? Two more papers just waiting to get busted... http://arxiv.org/abs/0908.1429v1 http://arxiv.org/abs/0908.1803

One reply to Pacome, though the discussion exceeds by far the relevance of the topic already. Baryonic DM is strictly limited by cosomology, if one believes in these models, of course. Anyway, even though most DM is cold, we are constantly bombarded by some DM particles that come together with cosmic radiation, solar wind etc. etc. If DM easily interacted with normal matter, we would have found it long ago. In the paper they consider DM as neutralinos, which are neither baryonic nor strongly or electromagnetically interacting.

well then I agree, how the fu.. they want to collect them !!!
A Fusion Thruster for Space Travel - IEEE Spectrum - 4 views
-
-
Instead of using deuterium and tritium as the fuel stocks, the new motor extracts energy from boron fuel.
-
"And according to his calculations, improvements in short-pulse laser systems could make this form of thruster more than 40 times as efficient as even the best of today's ionic propulsion systems that push spacecraft around. "
-
Dejan please have a look at this also ...
-
while the nuclear reaction seems to be sound at first view, I am not so sure how this would work: "Electromagnetic forces push the target and the alpha particles in the opposite directions, and the particles exit the spacecraft through a nozzle, providing the vehicle's thrust. "
New apps allow smartphone users to join the hunt for ultrahigh-energy cosmic rays - 0 views
-
Two apps - the Distributed Electronic Cosmic-ray Observatory (DECO) and Cosmic Rays Found in Smartphones (CRAYFIS) - transform smartphones into miniature cosmic-ray detectors. They use the CMOS chips inside phones' onboard cameras to detect the secondary particles produced when cosmic rays - energetic, charged subatomic particles arriving from beyond the solar system - collide with air molecules in the Earth's atmosphere

Eh, the swarm flyby gravimetry is very similar to the "measuring gravitational fields" project I proposed in the brewery
Popper's experiment realized again-but what does it mean? - 1 views
-
Although it may seem like the above two experiments violate the uncertainty principle because the results show a smaller-than-required degree of uncertainty, Shih and his coauthors explain that no violation has occurred due to the fact that the experiments involve photon pairs rather than individual photons. The scientists argue that Popper's original thought experiment was based on a misunderstanding of the proper context of the uncertainty principle: it governs the behavior of single particles only, not the "correlation" of two particles.
An Arty Oculus Trip Through the Large Hadron Collider | WIRED - 2 views

"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)
-
we will come when you figure out how to capture a particle!!! or a dragonball, is the same

The innovation turning desert sand into farmland - 1 views

Norwegian scientist Kristian Morten Olesen has patented a process to mix nano-particles of clay with water and bind them to sand particles to condition desert soil - he has been working on Liquid Nanoclay (LNC) since 2005.
-
The news here that some patent has been filed. If it actually works the guy is an ass for wanting to patent something that is solving world hunger. If it does not, then the guy is still an ass. So the news is that this guy is an ass :)
-
Agreed :) But, if it does work I doubt the guy will be able to enforce the patent in most of the countries where this will be helpful.
Pouring Milk All Over Yourself: The Next Extremely Bizarre Trend? - 1 views

So... who is in?

nice comment Johannes ... if you add a bit of Kleopatre, e.g. why bathing in milk helped her fool Marcus Antonius, your comment would be fully interdisciplinary :-)
-
you mean it would include History or Psychology? I would understand why Marcus Antonius might get fooled by a bathing beauty - but milk? DONKEY MILK?!? That's just wrong... :-[
