Comment Re:Rate of use (Score 5, Informative) 328

I suppose it really is to much to ask that people Read The Fucking Study...

In a nutshell, this study collected drug use data from 3095 drivers involved in crashes and 6190 matched control drivers. THC was detected in 234/3095 crash involved drivers, vs 379/6190 controls. That sample size is plenty. If you think otherwise, please explain why you think the studies' methodology is statistically underpowered.

The biggest caveat is probably that THC testing can be positive even if the drug use was days or weeks ago. I'm not aware of a test that, like BAC, can detect whether someone is high as balls right now. That makes the conclusions a bit weaker, but we can still conclude that people who frequently use marijuana are not riskier drivers than anyone else, and blood THC testing is not a measurement of impairment.

Comment Might be the perfect tablet for academia (Score 5, Interesting) 136

The Surface Pro 3 could be the best tablet I've seen so far to actually substitute for a paper notepad and stack of printed reading material. As a biology graduate student, I can envision several use cases that aren't well served by any other devices:

1) It could be the electronic lab notebook that so many scientists have been waiting for. Even though I use a desktop to write protocols and analyze data, I always end up using paper at the bench. If I write up a protocol, I print a copy so that I can carry it to the bench and scribble notes as I go. Similarly, for small and medium scale data collection, I record the data on a notepad and only later transcribe it to the computer. With OneNote, a good stylus, and a good aspect ratio for portrait, this could conceivably replace the binder full of papers I keep at my lab bench. (Difficulty: is it water and solvent resistant? Can it be covered in plastic without overheating or blocking the touch screen?)

2) This could be the best tablet for reading big stacks of 8.5x11 inch PDFs. It's got the right display size, aspect ratio, pixel density, and again the styles could be pretty handy. A 10" tablet is too small, particularly with a low resolution screen. Fingertips or capacitive styluses are too imprecise for highlighting and note taking. On the other hand, I find reading it tedious to read much on a desktop, even with a good monitor. At 800g, the Surface Pro 3 isn't even that heavy by paper standards: the textbooks I have next to me are 1-3 kg, and I have many stacks of journal articles that weigh more than 1 kg.

3) Finally, it could be a good tablet for the sorts of image manipulation I do. If it's good enough for Gabe at Penny Arcade, it should be more than good enough for my modest needs. I spend a lot of time with Inkscape and making figures for presentation and publication. (I even, I am ashamed to admit, use PowerPoint vector graphics more than anyone ever should.) It's never anything fancy, but I bet a good screen and stylus would be faster than doing everything by keyboard and mouse. Plus, I can use all of my usual scientific image processing software, and directly transfer processed images to other programs for further manipulation.

All of these uses are purely as a tablet or desktop replacement. I can't even see much use for the type cover to be honest, I'd rather just use the dock so I can plug in a real keyboard and mouse along with an external monitor.

However, it's way out of my grad-student budget. I'll be waiting for price drops (and other competitors) as I save up enough money. Or perhaps my research advisor has money budgeted for lab computers.

Comment Re:Sustainable? (Score 5, Informative) 328

This was my first concern. Some back-of-the-envelope calculations:

Photosynthesis is pretty lousy in terms of thermodynamic efficiency. About 1% of the light that hits a plant is converted to useful chemical energy. The plant will have to use most of that energy for its metabolic processes. Luciferase itself is a very efficient enzyme, however, so I'll generously assume that 10% of the energy that the plant captures can be turned into useful light. So the overall efficiency can't be much higher than 0.1%. By comparison, solar cells are around 10% efficient, and LEDs 20%, so at first glance the luciferase plant seems to be an order of magnitude less efficient than the solar powered flashlight my in-laws gave me for christmas.

In absolute terms, there is about 100 watts/meter^2 of energy in sunlight. If you've got a one-square-meter window full of the hypothetical plants sitting in sunshine all day, let's say they can absorb 1500 watt-hours, and then convert 1.5 watt-hours into useful light. That'd be comparable to running a 5-watt LED for an hourish, which could be useful if you could turn the luminescence on and off at will. But if the plant is glowing all night and only a portion of the light is emitted in a useful direction, maybe the window-full-of-plants would give off light comparable to the little cluster of LEDs on the front of my computer. So overall I'd say that the idea is not completely impossible, but still totally impractical.

Comment Re:Four Years??! (Score 1) 140

A "four year thesis project" sounds just about right to me. My particular program in biology has an average completion time of 5.5 years, and the national average I believe is 6.5 years. But I don't even have a formal thesis project until I write a proposal for the end of my second year. I spent my first year taking classes and doing research rotations. I'm currently in my second year, I've picked a lab and started to do some productive research, but I still have classes and TA duties, and I spent a lot of time this year learning the techniques that I will need for my thesis. So yeah, I'm aiming for a "four year thesis project".

I'm a little shocked that 10 or 11 years is at all normal. In my experience, anything beyond 7 years is the stuff of horror stories. 10+ years must be in fields where a grad student has to do their research after working as a TA for 30+ hours per week to afford their ramen.

Comment Re:Microscopes anyone? (Score 1) 71

Have you ever actually used a microscope? You can't just put one on an arm and wave it over a patch of dirt and expect to see anything interesting. Microscopes capable of resolving bacteria have a very tiny depth of field, so if you point it at a patch of ground there'd be nothing in focus. You have to take samples, mount them on a slide, stain them (usually), and then place them under a microscope. And on Mars, most potentially interesting microbes will probably be buried. To do that you have to have some fairly sophisticated sample handling mechanisms... which is exactly what this new mass spec instrument doesn't need. Now you just point it at an interesting patch of dirt, zap it with the laser, and suck all of the vaporized ions into the mass spec.

How To Make a Good Gaming Sequel 150

Kantor48 writes "In today's world of unimproved gaming sequels and saturated franchises, Arthur Kabrick looks at the best and worst sequels in recent history, and compares the changes they've made to the formulae of their franchises. By doing this, he comes up with a list of lessons that any game developer creating a sequel should follow, if at all possible, to ensure that the new game is a step up, rather than a step sideways or, as in some cases, a step down. The criteria include ensuring the game does not spend too much time in development, updating technology, and trying not to change the development team, as well as being wary of changing the basic formula so much that fans of the franchise are alienated."

Why Video Game Movie Adaptations Need New Respect 283

An anonymous reader writes "Hollywood has yet to find any video game property it is willing to treat with the same respect as J.R.R. Tolkien or J.K.Rowling, arguably still following the principles that led to the appalling Super Mario Bros. movie in 1992: 'A game lacks the complexity that a movie requires.' Yet a modern gaming masterpiece such as Mass Effect has the depth and breadth to deserve better treatment in the proposed trilogy. Is Hollywood again going to disrespect fans who, in this case, have as much right to see a good plot respected as the readers of Lord Of The Rings? This article discusses why and how Hollywood should grow up regarding these adaptations."

Witcher 2 Torrents Could Net You a Fine 724

An anonymous reader writes with this quote from Eurogamer: "Gamers who download upcoming PC exclusive The Witcher 2 illegally could receive a letter demanding they pay a fine or face legal action. If gamers refuse to pay the fine, which will be more than the cost of the game, they could end up in court, developer CD Projekt told Eurogamer. 'Of course we're not happy when people are pirating our games, so we are signing with legal firms and torrent sneaking companies,' CD Projekt co-founder Marcin Iwiski said. 'In quite a few big countries, when people are downloading it illegally they can expect a letter from a legal firm saying, "Hey, you downloaded it illegally and right now you have to pay a fine." We are totally fair, but if you decide you will not buy it legally there is a chance you'll get a letter. We are talking about it right now.' Interestingly, The Witcher 2 will be released free of digital rights management – but only through the CD Projekt-owned digital download shop That means owners will be able to install it as many times as they like on any number of computers – and it will not requite an internet connection to run."

Woman Develops Peanut Allergy After Lung Transplant 146

An anonymous reader writes "A woman in need of a lung transplant got her new lungs from someone with a peanut allergy who died of anaphylactic shock. Seven months after the surgery, the woman was at an organ transplant support group when she ate a peanut butter cookie and had a violent allergic reaction. So how had the woman's new lungs brought along a peanut allergy? A blog post dives into the medical details and explains that immune cells in the donated lungs couldn't have lived in the new body for long enough to cause the reaction... however, if they encountered an allergen (i.e. something peanuty) shortly after being transplanted, they could have trained the woman's native immune cells to respond."

Valve Announces Dota 2 128

RulerOf writes "Just over a year after hiring IceFrog, the lead developer of the wildly popular DotA Allstars mod for Warcraft III, and the speculation surrounding Valve's recent trademark filing for the 'DotA' name, Valve has officially announced Dota 2. Gameplay of Dota 2 is being ported 'exactly' from the current DotA Allstars and includes every hero, but vast improvements are being made to the game including VoIP, a coaching system, in-game rewards, and AI that takes over for disconnected players. Lastly, it all runs on top of the Source engine. (GameInformer's website appears to be struggling right now though, as they had an exclusive on this story.)"

Badgers Digging Up Ancient Human Remains 172

One of England's oldest graveyards is under siege by badgers. Rev Simon Shouler now regularly patrols the grounds of St. Remigius Church looking for bones that the badgers have dug up. The badger is a protected species in England so they can not be killed, and attempts to have them relocated have been blocked by English Nature. From the article: "At least four graves have been disturbed so far; in one instance a child found a leg bone and took it home to his parents. ... Rev. Simon Shouler has been forced to carry out regular patrols to pick up stray bones, store them and re-inter them all in a new grave."

BioWare On Why Making a Blockbuster Game Is a Poor Goal 192

BioWare co-founder Greg Zeschuk spoke at the 2010 Develop Conference about the current focus within the video game industry on making huge, blockbuster titles, and why that is the wrong approach. Quoting Gamasutra's coverage: "'While blockbuster game creation is everything that most game developers working today growing up wanted to do, it's precisely the wrong thing to chase in gaming's contemporary landscape.' Risk-taking from publishers and investors has dramatically declined in recent times, the Mass Effect and Dragon Age studio-runner noted: 'As a result, innovation and creativity [are] being squeezed. Where the bottom of the market had dropped out at one point, now it’s the middle of the market has dropped out. Unless you can be in the top ten releases at one given time, it's unlikely that a triple-A game is going to make money.'" Zeschuk also commented that consoles aren't necessarily the future of game platforms, and that BioWare is experimenting with smaller scale MMO development in addition to working on their much larger upcoming Star Wars title.

Dragon Age 2 Announced 183

Today BioWare announced a sequel to Dragon Age: Origins, titled Dragon Age 2. They've opened an official site for the game, which shares some vague details and concept art, and promises a trailer in mid-August. The story will apparently span an entire decade and involve a new hero, but it will be located in the same world as the original game. The site says there will be "dynamic new combat mechanics," though the same three basic classes will be available. More information should be forthcoming in this month's issue of Game Informer.
