BP Claims Gulf Well Has Been Stopped 601

An anonymous reader writes with word that BP has announced the Gulf oil spill has been stopped. Another reader adds more detail: "The last valve on the new cap has been closed, and the flow of oil and gas into the sea has stopped. That doesn't mean it's over. It is unclear whether the steel casing deep in the well can contain the pressure. The risk is that it could burst, which would eventually cause a rupture on the sea floor that would make things much messier to deal with. However, they're monitoring the pressure buildup carefully and if the pressure holds over the next 48 hours (indicating there is no leak below the sea floor), they'll assess what to do next. If it doesn't hold at the expected readings, then they'll re-attach the pipe used for producing to the surface and start collecting again. Regardless of what happens the relief well still has to be completed to permanently plug the well with cement, which could take a couple more weeks."

Proximity Sensor Presents Latest iPhone 4 Issue 446

tekgoblin sends news of the latest iPhone 4 glitch being reported in user forums and elsewhere: the phone's proximity sensor seems not to be detecting nearby faces, as it is designed to do, in order to deactivate the screen during a call. The result is often unintended input. "On the iPhone 3GS, the proximity sensor was located to the left of the earpiece speaker. But that space on iPhone 4 is now occupied by the front-facing camera, and the proximity sensor is above the earpiece. What's not clear is whether the iPhone 4 screen's misbehavior is due to the new location of the sensor, or it's because Apple tweaked the sensor's responses in [some] way."

Adobe Finally Fixes Remote Launch 0-Day 82

Trailrunner7 sends in this excerpt from Threatpost (Adobe announcement here): "Adobe today shipped a critical Reader/Acrobat patch to cover a total of 17 documented vulnerabilities that expose Windows, Mac, and Unix users to malicious hacker attacks. The update, which affects Adobe Reader/Acrobat 9.3.2 and earlier versions, includes a fix for the outstanding PDF '/Launch' functionality social engineering attack vector that was disclosed by researcher Didier Stevens. As previously reported, Didier created a proof-of-concept PDF file that executes an embedded executable without exploiting any security vulnerabilities. The PDF hack, when combined with clever social engineering techniques, could potentially allow code execution attacks if a user simply opens a rigged PDF file." Relatedly, Brian Krebs blogs about the downsides of Adobe's increasingly Byzantine update process.

The "King of All Computer Mice" Finally Ships Screenshot-sm 207

An anonymous reader writes "The much-anticipated, much-mocked 18-button joystick mouse from WarMouse is now shipping. The press release features an impressive set of user quotes from game designer Chris Taylor, new SFWA president John Scalzi, and a doctor who runs a medical software company. Crazy or not, it's obviously more than just a gaming mouse."

Tattoos For the Math and Science Geek? 1186

An anonymous reader writes "I've been thinking of getting a sleeve of math and science tattoos for quite a while now. With the money saved up, the only question remaining is, what equations/ideas should I get? I know for certain that I'm going to include some of Maxwell's equations, and definitely Ohm's Law. So, if you were going to put a tribute to the great math and science minds on your body forever, which ones would you choose?"

There are, however, many quality degree programs in Statistics. As someone who went through one of them, you can largely choose your own mix of theory and practice. I wonder if this isn't just statistics rebranded? I hope it doesn't concentrate too much on certain proprietary software packages. Statistics is like anything else. You can easily produce a bunch of numbers and compile massive books of tables and graphics. But if you don't know the assumptions of each of your methods, and consequently their shortcomings in each situation, you can draw some fairly bad conclusions rather quickly. I just hope this program gives a solid background in theoretical statistical inference, experimental design, and regression analysis, so students understand the 'why'.

NASA Aircraft Videos Hayabusa Re-Entry 56

astroengine writes "Flying above the Australian Outback, NASA's converted DC-8 jet videoed the violent re-entry of the Japanese Hayabusa spacecraft. Flying in front of the disintegrating probe, the mission's sample return capsule can be seen speeding though the atmosphere. According to reports, the capsule landed safely and will be collected by helicopter in the morning." "Bad Astronomer" Phil Plait posts about the successful return as well.

NASA Astronomers To Observe Hayabusa's Fiery Homecoming 142

coondoggie writes "NASA said that a group of its astronomers will have a front row seat in Australia to watch the Japanese spacecraft Hayabusa's high-speed, fiery return to Earth. It is bringing with it a hunk of the asteroid Itokawa. The spacecraft is expected to land in an unpopulated area of Australia at approximately midnight locally, or 7 am PDT, on Sunday, June 13. Some 30 NASA astronomers will be flying onboard a specially equipped DC-8 with instruments that can monitor Hayabusa's reentry."

What Gamers Have In Common With Top Athletes 201

nk497 writes "It's no surprise that professional gamers aren't quite as fit as elite athletes, but they do have something in common. According to a British academic, top-level players show similar psychological attributes as top athletes, such as the ability to manage anxiety, and have reaction times on par with fighter pilots. Dr. Micklewright said, 'When I first got asked to do [the study], my initial reaction was "don't be ridiculous, gaming is nothing like sport." But the more I thought about it, the more similarities [became clear], and I became more and more convinced that it was close in many ways to sport.' While sitting in front of a screen might not have the same physical demands as running a marathon, neither do playing snooker or darts. Still, while gamers show good reflexes, their health was worse than expected, with one 20-something professional player showing the same aerobic health as a 60-year-old smoker." This story is based on a BBC radio report which you can currently hear, although that link seems to say that it won't last.

In my experience, what you describe, accounting, is a separate discipline under the Business school, where Economics is usually its own department. An Econ major would almost never need to take a single accounting class I imagine, if they chose not to.

Lidar Finds Overgrown Maya Pyramids 169

AlejoHausner writes "A team of archaeologists scanned the jungle of Belize with lidar. Although most of the reflections came from the jungle canopy, some light reflected off the ground surface. Using this, suddenly hidden pyramids, agricultural terraces, and ancient roads are revealed, at 6-inch resolution. The data allowed the archaeologists to bolster their theory that the ancient city of Caracol covered more than 70 square miles of urban sprawl and supported a population of over 115,000."

Hacking Vim 7.2 246

briancarper writes "Vim is an open-source text editor with a power and flexibility matched only by the steepness of its learning curve. As the author of this book states, 'Vim Can Do Everything' but configuring it to do so is sometimes daunting. Hacking Vim 7.2 aims to help the average Vimmer get the most out of customizing Vim, for fun and productivity." Read on for the rest of briancarper's review.

I am a biostatistician.

I have not read the details of this study, but consider the following example, with included R code so you can replicate it. It is a hypothetical study where 6 subjects are randomly determined to be administered treatment, and 6 subjects are randomly given placebo. All 6 in the treatment arm are cured of blindness. None of the 6 in the placebo arm are. The p-value for Fisher's exact test, which is a *conservative* test (i.e., has lower size than the proclaimed alpha level) yields a p-value of ~ 0.002, a highly significant finding. Granted, N = 12, not 6, in my study, but only 6 were given treatment.

Your claims about this not demonstrating safety are valid, as this study was not powered to detect safety issues. But a follow-up study surely will be.

My point is that you don't need a large sample size to prove something causes an event if the odds of the event happening spontaneously are practically nil, as my example shows. And as another poster pointed out, this is how medical research progresses, and you screaming on Slashdot what every third-rate scientist in the medical profession already knows is pointless.

R code:
trial = data.frame(trt = rep(c("Treatment", "Placebo"), each = 6),
                                        out = rep(c("Cured", "Not Cured"), each = 6))

tbl = table(trial$trt, trial$out)

fisher.test(tbl)
