A Florida university has broken ground on a new hurricane simulation machine capable of recreating category 5 hurricanes in three dimensions.
The facility will not only allow scientists to study hurricanes, they will also be able to test the engineering of objects trying to survive them.

Are the glaciers in the Himalayas shrinking? A third paper published today falls between one study that said no and another that said yes.
The uncertainty of science: Are the glaciers in the Himalayas shrinking? A third paper published today falls between one study that said no and another that said yes.
The new estimate raises further questions about satellite and field measurements of alpine glaciers, and ”will set the cat among the pigeons,” says Graham Cogley, a remote-sensing expert at Trent University in Peterborough, Ontario. … Although the ICESat results show twice as much ice loss as the re-interpreted GRACE data, this figure is still three times lower than regional losses estimated on the basis of field studies.

One of Curiosity’s two wind sensors has been found to be damaged and is inoperable.
One of Curiosity’s two wind sensors was apparently damaged in landing and is inoperable.
The Rems team first noticed there was something wrong when readings from the side-facing boom were being returned saturated at high and low values. Further investigation suggested small wires exposed on the sensor circuits were open, probably severed. It is permanent damage. No-one can say for sure how this happened, but engineers are working on the theory that grit thrown on to the rover by the descent crane’s exhaust plume cut the small wires. The wind sensor on the forward-facing mini-boom is unaffected. With just the one sensor, it makes it difficult to fully understand wind behaviour.

Astronomers have now confirmed 41 new exoplanets, first pinpointed by the Kepler space telescope
Astronomers have now confirmed 41 new exoplanets, first pinpointed by the Kepler space telescope.
One paper, by Jiwei Xie at the University of Toronto, confirms 24 new planets in 12 systems. Another study, by Steffen and his colleagues, confirms 27 planets in 13 systems. Five of the systems, and 10 of the planets, are the same in both papers. All in all, the new research adds 20 new planetary systems to the 47 that Kepler had previously confirmed, marking a more than 40 percent increase.
Among the Kepler candidates are five Earth-sized planets in the habitable zone, according to the vidoe at the link. However, this announcement does not tell us if any of those candidates were confirmed by these two papers.
NASA has announced its next planetary mission, a lander to Mars that will drill down thirty feet into the planet’s surface
NASA has announced its next planetary mission, a lander to Mars that will drill down thirty feet into the planet’s surface.
Though exciting in its own right, this mission is far less ambitious than the two missions which competed against it, a boat that would have floated on the lakes of Titan and a probe that would have bounced repeatedly off the surface of a comet. I suspect the reason this mission was chosen is the tight budgets at NASA, combined with Curiosity’s success which makes it politically advantageous to approve another Mars mission. As the NASA press release emphasized,

On August 13, 2012, Voyager 2 became the longest-operating spacecraft in history, finally topping Pioneer 6, which was launched on Dec. 16, 1965, and sent its last signal back on Dec. 8, 2000.

And Voyager 2, along with its partner Voyager 1, are still working, and engineers hope they will still be working for another eight to twelve years, enough time for them to leave the solar system and enter interstellar space.
Engineers at Sandia National Laboratories have developed a robot hand that costs less than $10,000.
Engineers at Sandia National Laboratories have developed a robot hand that costs less than $10,000 and is capable of replacing a flashlight battery.
The researchers were able to scrimp in a number of clever ways. “One was scouring the globe for the least expensive, highest-performing components like motors, gears, etcetera,” says Curt Salisbury, the project’s principal investigator. “Another was to build the entire electronics system from commodity parts, especially those found in cell phones. We also moved from metal structural elements to plastic, being careful to design the structures so plastic would provide adequate strength.”
The article focuses on the potential of using such a robot hand to defuse bombs. I see it as a first step in providing amputees a replacement hand that is fully functional. And that their goal is to bring the cost down to $1,000 is even more exciting.
