It's hardly a hack if you have to install malware on the air-gapped device first. The whole point of air-gapping is to prevent the unauthorized uploading and downloading of information. If you can get close enough to the air-gapped computer to install malware, you can get close enough to steal data...

But it's still a hack, and it still allows you to steal *future* data without further access. Yes, air-gapped computers aren't supposed to have someone bringing in and out USB, but it's much easier to do that one time than again and again, or even if the person doing the compromising is doing the setup of the computer, or doesn't realize it when using someone else's software package. And the fact of it being an air-gapped computer could give people a false sense of security. "We don't need to check for malware, because this is a protected computer." The main point I take away from the exercise is "don't get lax on security just because you think your computer is air-gapped".

Fair enough, I just thought the headline was misleading, but I suppose that's SOP these days.

I heard that ophthalmologists were freaked out by the possibility of cataract surgery going bye-bye. Leaving aside the fact that those eye drops probably won't work for everyone (because what medication works for everyone?) and that patients it will probably require a lot of monitoring (at least at first), I guess we know what they'll be doing instead: Retinal implants. Which is way more intensive than cataract surgery and will yield them way more lucrative surgical hours per patient (while they continue to charge for cataract diagnosis, drop prescriptions, and medication monitoring on their non-surgical days).

Also, you don't need anesthesiologists to work on the lens. You do need anesthesiologists to work on the retina. More billable procedures for everyone!

According to my dad, a recently retired doctor, there's actually not that much money in surgery anymore. That used to be where all the top MDs would go since it paid the most, especially with on call stuff. Over the years though hospitals have been cutting away(ha) the amount little by little so it's been passed by other areas of medicine.

Anesthesiologists are being replaced by nurse anesthetists. The hospital still gets billable time, but at a reduced rate.

At first I thought the link was going to say orthodontists. Dentists make more on average than doctors, which seems to indicate that 3rd party payment is likely not the key driver of medical wages, but rather cartel practices.

The "Lucy" auto-adjusting solar light looks pretty cool, but the more I think about it the less sure I am how useful it actually is. For one thing, it's most powerful on sunny days...which is when you'd need it least. The room has to get direct sunlight, but still need more light. (Or need light, and be within line of sight of a room that has direct sunlight.) It won't be much use on cloudy days and none at night. And at $300, it's a lot more expensive than buying a couple floor lamps and some CFL bulbs.

Plus, how much good does it do to 'track the sun' unless you manage to put it right on the windowsill? And if it's for that, why make it all round? If it's on a table a couple feet inside the window, the sun will move off the mirror.

A private fusion company has apparently broken the world record for containing a ball of plasma, holding it 16 times longer than previous groups.

http://news.sciencemag.org/physics/2015 ... eakthrough

I still don't think it will amount to anything because fusion. Also, no peer-reviewed report and no demonstration open to skeptical investigators. However, if this is true, it is moderately interesting to me for three reasons:
1) It was done cheaper than most work of this sort.
2) They (allegedly) broke a record by a pretty wide margin.
3) Their plan to use hydrogen-boron fusion and eliminate neutron emission (which damages the reactors) is interesting. Then again, I don't know what sorts of side reactions might be going on at that temperature.

Also, I don't think this will amount to anything because fusion.

Here's something bizarre and interesting I ran across almost at random: the vacuum catastrophe. No, it does not involve someone attempting to use a Hoover for personal gratification, it's
the disagreement of over 100 orders of magnitude between measured values of the vacuum energy density and the theoretical zero-point energy suggested by quantum field theory. This discrepancy has been described as "the worst theoretical prediction in the history of physics."

The magnitude of this discrepancy is entirely beyond the descriptive power of any kind of commonplace comparison. For instance, the statement "the universe consists of exactly one elementary particle" is closer to being true, by at least ten orders of magnitude, than the incorrect vacuum-catastrophe prediction.

It's official: we have autonomous killer robots on the loose. They are, admittedly, only killing invasive Crown-of-Thorns starfish.
The COTSbot is an Autonomous Underwater Vehicle (AUV). This class of robot is designed to operate without a tether and execute missions with minimal human interaction once deployed. The primary task of the COTSbot AUV is to autonomously navigate within complex reef environments and automatically detect COTS (Crown Of Thorns Starfish) on the coral and administer an injection.
Put simply, when released into the water, it moves around looking for COTS, and when it finds one,it injects the starfish with bile salts, which kills it rapidly.

I agree in principle, but isn't that kind of begging the question in assuming that there is a substitute way to get a properly functioning ecosystem in the case of an invasive like that? And humanity and the world has been down that road of trying to combat one invasive species with another, only to find that the second invasive is at least as bad as the first, or doesn't even get rid of the first, so you have two. It's not like a drone like that will become an invasive itself (that's an argument for other drones).

All true. You've got to restore some semblance of balance (loosely speaking, as the balance of nature (really, equilibrium theory) is a discredited ecological paradigm).
