China Aims To Build World's Largest Rocket

hackingbear writes “Back in March, China revealed it is studying the feasibility of designing the most powerful carrier rocket in history for making a manned moon landing and exploring deep space, according to Liang Xiaohong, vice head of the China Academy of Launch Vehicle Technology. The rocket is envisaged to have a payload of 130 tonnes, five times larger than that of China’s current largest rocket. This rocket, if built, will eclipse the 53 tonne capacity of the planned Falcon 9 Heavy from SpaceX. It will even surpass the largest rocket ever built, the 119-tonne Saturn V. China’s next generation rocket Long March 5, currently scheduled to debut in 2014, has a payload capacity of 25 tonnes to LEO.”

New Spin On Graphene Makes It Magnetic

intellitech writes “A team led by Professor Andre Geim, a recipient of the 2010 Nobel Prize for graphene, has shown that electric current can magnetize graphene. The researchers found a new way to interconnect spin and charge by applying a relatively weak magnetic field to graphene and found that this causes a flow of spins in the direction perpendicular to electric current, making a graphene sheet magnetised.”

Portable brain tumor treatment system kills cancer while you take out the trash

We’ve seen robots that perform brain surgery and lasers that cook tumors, and now a team of researchers are well on their way to bringing mobility to the battle against brain cancer. The NovoTTF-100A, which just received FDA approval, is basically a set of insulated electrodes, attached to an electronic box, that pumps low intensity electrical fields to the site of a freshly diagnosed GBM (glioblastoma multiforme) tumor. The fields, known as Tumor Treatment Fields (TTF), play off the electrically charged elements of cancer cells to stunt the tumor’s growth, and may in some cases actually reverse it. A recent test of the system showed comparable results to chemotherapy, without the usual lineup of side effects, including nausea, anemia, fatigue, and infection. Given, patients using the system are expected to wear the thing continuously, but we’d say walking around with a cap full of electrodes is a small price to pay for giving cancer the boot. Full PR after the break.

The Harmonica Pistol

Here’s one early solution to the problem of limited magazine capacity. Between 1859 and 1862, a French inventor named Jarre patented several so-called harmonica pistols. As often as the user needed a fresh round, s/he could just push the magazine laterally. The pinfire example pictured above could hold nine 9mm cartridges.

Egyptian Mummy Wore World’s Earliest Known Prosthesis

Archaeologists have recovered a three-jointed set of prosthetic toes attached to a mummy in Egypt. Due to its age, this object is likely the oldest known prosthesis. From a 2007 Live Science article:

Archaeologists speculated the 50- to 60-year-old woman the prosthesis came from might have lost her toe due to complications from diabetes.

The wood and leather prosthesis dates from 1069 to 664 B.C., based on artifacts it was found with in the mummy’s burial chamber. This means it predates what was previously thought of as the earliest known functioning prosthesis, the Roman Capua Leg, a bronze artifact dating from about 300 B.C. The leg was once at the Royal College of Surgeons in London but was destroyed by bombing during World War II.

US government contractor developing ‘microwave gun,’ Hot Pockets tremble

Ah, the beloved “electronic bomb,” able to disable all technology in its vicinity: variations on the concept go way back, but useful prototypes remain tantalizingly out of reach. Into the breach steps defense contractor BAE Systems, taking a fresh crack with a High-Powered Microwave (HPM) gun intended to disable small boat engines – if successful, the technology may also target ships, UAVs, and missile payloads. The secret-shrouded weapon sounds similar to Boeing’s planned airborne EMP weapon, but lacking the missile delivery systems. BAE seems to be betting big on electromagnetic warfare as a future battlefield tactic, with a manager pitching the sci-fi scene to Aviation Week:
“Unlike lasers, HPM beams don’t need a lot of accuracy. With a fan [of HPM energy] you can target 10-30 small boats. If you can knock out 50-75% of the engines in a swarm, you can then concentrate on the remainder with lasers or kinetic [cannons].”

To develop better defenses against such attacks, the contractor received $150,000 from the Air Force to test-fire microwaves at military computers. No word on whether said defenses involve generous use of tin foil.
