Really?

Guardian wakes up after 20 years of hibernation, nothing new here. To have money you need to publish, to publish you need results, to have results you either make them or steal them. Of course if can go to the little fraud as quoting without explicitely saying where you take it to totally "forgetting"to show the bad results, bad of course being subjective here.

It's even more true in anglo saxon university, since it's the university who are supposed to check if people fake their results, but if they do so, it will ruins their reputations. Better to not see what you don't want to see.

Maybe it will change if the way research if funded and above all is published change one day.

High-Res Curiosity Rover Self-Portrait Is Mind-Blowing

Keep the dream alive NASA! Maybe someday we'll be able to actually live on the red planet (and it'll be covered in water and beautiful girls will drive people around in gondolas...)

As long as money is involve fraud (any kind) will never end.

I am very surprised no one here (or in slashdot) has mentioned this article about the cure for cancer. Of course we are years from getting such cure from your local physician )they are only starting lab rat tests). But the basics are sound, all cancers share one characteristic of reproducing at an abnormal speed in low oxygen environments since they use sugar from the bloodstream instead. This treatment blocks the sugar conversion process, which leads to apoptosis (cell suicide) in all cancer cells. Normal cells seem unaffected.

Sorry for the late comment, my take on this. imo BOTH are correct, speed of light CANNOT be attained by particles with mass (because attaining infinite mass would mean you have all the mass in the universe) and speeds highers than light CAN be attained. It might contradict common sense, but if you think for a moment ice can change into vapor without through the liquid state (look for "sublimation"). The comment in the article about mass going near zero as speed goes near infinity might mean that there might be some way to reduce the strength of the higgs boson (the so called "god particle") as to lower the atomic mass while at the same instant attaining higher than light speeds. Of course this is purely theoretical, but isn't it fun? To think there might be particles in the universe we cannot see because they are traveling faster than light, maybe it is the so called dark matter which calculations say it is out there but we cannot see.

Guess loud speaks will be a need in space at last.

Anyway.

More junk in space... with no scientific benefit. This operation is just a public relations stunt for Cambridge university.

31 year-old Zac Vawter made history on Sunday when he became the first person to scale the 103 flights of stairs in Chicago’s Willis Tower with a mind-controlled robotic leg, reports the Associated Press. The artificial limb takes advantage of targeted muscle reinnervation (TMR), a technique that connects nerves severed in an amputation to other, viable muscles. In Vawter’s case, the nerves that would ordinarily control his missing lower leg have been rerouted to his hamstring, whose electrical impulses are converted into control signals that move his prosthesis.

Navy Researchers Look to Rotating Detonation Engines to Power the Future:

"NRL researchers believe that RDEs have the potential to meet 10% increased
power requirements as well as 25% reduction in fuel use for future Navy
applications."

"Like PDEs, RDEs have the potential to be a disruptive technology that can
significantly alter the fuel efficiency of ships and planes; however, there are
several challenges that must be overcome before the benefits are realized,
explains Dr. Kailasanath."

Flight Tests For Vortex Rocket Combustion:

"An innovative combustion-chamber setup that was flight-tested last month could
cut the cost of rocket engines by eliminating the need for regenerative cooling.

Orbital Technologies Corp. (Orbitec), a Madison, Wis.-based space-technology
company, flight-tested a version of the 30,000-lb.-thrust liquid-propellant rocket
engine it is developing for the U.S. Air Force's Advanced Upper Stage Engine
Program (Ausep) and other in-space applications."

Scientists at Harvard's Wyss Institute have managed to recreate a pulmonary edema (a build-up of fluid in the lungs) inside a lung-on-a-chip. The team used techniques similar to those developed for microchip manufacturing to build the mechanical structure of a lung before lining it with human tissues. Air is passed through one side of the lung, while a liquid solution containing white blood cells mimics blood on the other side.

Quantum Computing Could Rip Open Most of the World’s Secret Codes — Someday:

"Still, there is an international race underway. Russia, China and others are all
trying to harness quantum’s potential, and the U.S. is determined to solve the
puzzle first. To that end, Washington is underwriting millions of dollars of research
each year.

At stake is an almost unimaginable power. As Wineland explains it, quantum
computers would have more unique combinations of bits at their disposal than
there are “elementary particles in the universe.”"

moonbase anyone?

50 years ago, President John F. Kennedy told the United States that man would go to the moon. Soon, another American president may announce that the same celestial body will serve as a waypoint for manned space exploration. The Verge has learned that NASA intends to deploy a robotic lunar rover on the Moon in 2017 to search for water and other resources necessary for space travel, and that NASA may have secured support from the White House for an actual manned outpost — a space station — floating above the far side of the moon

Not that new, but the craziest math exam in history:

http://arxiv.org/pdf/1110.1556v2.pdf

The exam was used to reject undesired jew applicants in a Soviet university while keeping up appearances. The problems are difficult but suprisingly elegant. Can you solve any of them?
