The EPA takes initial step towards regulating lead fuel used by small planes
The EPA has highlighted some of the environmental and public health risks associated with lead emissions. The agency wants to begin regulating the use of leaded fuel still often used in smaller airplanes.
Hitting the Books: Why America once leaded its gasoline
Automakers have been fighting to eliminate Engine knock since the days of the Model T. Their initial attempts to fix it, as University of Manitoba's Professor Vaclav Smil explains in "Invention and Innovation," went over like a lead balloon.
Elon Musk said he will pay for home water filters in Flint
Four years ago, the Flint water crisis began when officials switched its source from Lake Huron to the Flint River. Its more corrosive water caused dangerous levels of lead from old pipes to leach into the city's drinking water, poisoning residents. Now, after fighting with officials just to get the problem recognized in 2015, many residents still don't trust the city's tap water. Into the fray steps Elon Musk, fresh off of his submarine-building exploits, responding to a tweet with this promise "Please consider this a commitment that I will fund fixing the water in any house in Flint that has water contamination above FDA levels. No kidding."
University of Michigan teams with Google to track Flint water crisis
Thanks to the prolific ineptitude of elected officials, the water in Flint, Michigan has been tainted with lead and undrinkable for more than a year. And while the federal government has, just last week, finally gotten around to earmarking $170 million for infrastructure improvements in the blighted city, tangible relief for its residents is still months if not years away. A new app developed by the University of Michigan with backing by Google will help those living in Flint track the rebuilding progress.
Large Hadron Collider may have produced a previously undetected form of matter
Teams at the Large Hadron Collider must be developing a knack for producing tangible evidence of theoretical particles. After orchestrating 2 million collisions between lead nuclei and protons, like the sort you see above, the collider's Compact Muon Solenoid group and researchers at MIT suspect that stray, linked pairs of gluon particles in the mix were signs of color-glass condensate, a currently theory-only form of matter that sees gluons travel in liquid-like, quantum-entangled waves. The clues aren't definitive, but they were also caught unexpectedly as part of a more routine collision run; the team is curious enough that it's looking for more evidence during weeks of similar tests in January. Any conclusive proof of the condensate would have an impact both on how we understand particle production in collisions as well as the ways gluons and quarks are arranged inside protons. If so, the CMS and MIT teams may well answer a raft of questions about subatomic physics while further justifying CERN's giant underground rings.
Nissan Leaf to go farther and cost less in 2013
Wondering what the coming year will hold for Nissan's flagship electric car? Well, as expected, there's a small, but not negligible range boost in store. On a full charge, and with all the other electronics turned off, the 2013 Leaf should be able to eke 228 km (142 miles) out of its lithium ion pack, which is up from the 200 km (124 miles) of last year's model. There's also a new battery gauge that tells the driver how much juice is left in percentage points, instead of just miles remaining. The price of entry has also been seriously lowered, putting the EV within the reach of many more consumers. In Japan, the base model will cost just ¥2.5 million (roughly $31,000), significantly less than the 2012 edition which had a starting price of just under ¥3 million (around $37,000). While there's no guarantee that price drop with carry over stateside, we'd say it's a pretty good bet that a cheaper Leaf in our future. Sadly, there's no word about that fancy inductive charger.
iPhone 5 chemical study shows a green Apple, leaves room for improvement
Eventually, that shiny new iPhone 5 will have to meet its untimely end, whether it's in a landfill or (preferably) a recycling company's machinery. When it does, you'll at least be glad to know that Apple has kept the toxin levels down. HealthyStuff and iFixit have dissected the extra skinny smartphone and put it in the same "low concern" category for potential harm that's normally occupied by phones wearing their green credentials on their sleeves. Lest anyone rush to tell Greenpeace about the feat, just remember that there's a difference between proficiency at excising dangerous chemicals and getting rid of them completely: HealthyStuff still found small traces of bromine, chlorine, lead and mercury in the iPhone 5's construction, which could pose risks if the handset is ever broken apart or melted for scrap. Some concern also exists that the x-ray fluorescence spectrometer doesn't reveal the full extent of any toxic materials. Whether or not these remain sore points for you, the new iPhone is at least easier on the eco-friendly conscience than most of its peers.
Vox jams guitar amps into Audio-Technica headphones, dubs them Amphones (ears-on)
Guitarists and Bassists have many tools at their disposal for practicing fresh news licks without disturbing others around them. One of our favorites is Vox's AmPlug -- a guitar amp-modeling dongle that plugs into your instrument's 1/4-inch jack, allowing you to connect headphones and an MP3 player to practice privately. Building on the idea, Vox worked with Audio-Technica to simply embed the AmPlug in a new line of headphones, dubbing them Amphones. The company quietly put the cans up on its site recently, and it's now officially ready to shout out loud about them. Guitarists can choose from AC-30 (British crunch), Lead (hi-gain) and Twin (clean) variants, and bassists can snag the Bass version, which is based on Vox's AC100. Just like the AmPlug, each Amphone features volume dials -- sadly, these don't go to 11 -- for setting gain, volume and tone, along with a fourth for a built-in effect (compression for the Bass and reverb with the AC30, for example). A duo of triple AAs power the cans and, as you'd expect, the 'phones have a 3.5mm jack for hooking in external sources as well as a 1/4 adapter to plug into your axe. These Vox-styled units will be available in the US sometime in October for $100 a pop (double the cost of an AmPlug). Hungering for more already? We were able to give a pre-production version of the AC30 model a brief run, and you'll find our initial impressions after the break.
Google+ design credited to original Macintosh team member Andy Hertzfeld
You may have heard about Google+, the hot new sharing product from Google that went official today, and it sounds cool (sounds cool, but remember how cool Wave and Buzz sounded? Let's just say we're reserving excitement so far). But one exciting thing about the new project is how cool and smooth it looks, and TechCrunch has noted the reason for that look, based on Steven Levy's reporting: it's designed in part by Andy Hertzfeld, one of the members of the original Macintosh team back in the 1980s. Hertzfeld now works for Google, and supposedly he was let free to exercise his creative influence as he liked on the new Google+ system, creating something for the folks in Mountain View that looks like it might have come from the early days of the Cupertino company. Hertzfeld even credits some of his influence at Google to Apple's own resurgence lately, saying that Apple's sky-high relevance in the tech and mobile industry may have "had a little bit to do" with his chance to help create Google+. In other words, when you finally get one of those invites that are starting to float around, and finally log in to the system to see what it is and what it's like, take note of any Macintosh-related influences you might see. Odds are, they're Mr. Hertzfeld's work.
Silicon chips get speed boost with a lead start
In tennis, the materials of the tennis court affect the performance of the ball. Such is the case, on a much, much smaller scale, for electron movement across circuitry. Silicon chips give resistance that lowers the speed limit, while atom-thick sheets of carbon (a.k.a. graphene) have a special property whereby free electrons are almost weightless and can travel up to 0.003 times the speed of light -- sounds great, but it's hard to produce in bulk. Cut to Han Woong Yeom and Pohang University of Science and Technology in South Korea. His team has added a thin layer lead on a silicon chip, lowering the electron mass (and thus proportionally raising its speed) to 1/20th compared to standard silicon. Still a ways to go for graphene speeds -- by a factor of three, according to Yeom -- but it's also more likely to mass production.
Raid Rx: Help! How do I start organizing my healers?
Raid Rx has returned from retirement! Every Thursday (usually), Raid Rx will help you quarterback your healers to victory! Your host is Matt Low, the grand poobah of World of Matticus and a founder of PlusHeal, a new healing community for all restorative classes. This week I explore a few questions that new healing leaders have. This is a question that caught my attention on the Plusheal forums. Julanna just became their guild's de facto healing lead and had some important questions to ask. So, I have become our de facto healing lead. We have very little structure. We need some. I am not sure how to get some coordination going between our healers. How do you communicate with your healers? How much do they expect from you in terms of instructions or advice? Is it before the raid? During? How can you get the raid leader to understand that healing assignments other than "don't let people die" are important and make things go better (especially if it is a tank with a healer alt)? I am not positive about assigning other classes of heals, and I am the only holy priest. Any resources out there I should look at? That may inform me of other classes basic skills, spells, etc? Or any advice you may have from a newb officer, newb healing lead, newb progression raider from a new guild? I'll break up these questions individually and answer them based on my own experience.
Raid Rx: Are you ready to be the healer leader?
Raid Rx has returned from retirement! Every Thursday (usually), Raid Rx will help you quarterback your healers to victory! Your host is Matt Low, the grand poobah of World of Matticus and a founder of PlusHeal, a new healing community for all restorative classes. Today, it is all about the healing leader and what you need to know if want to do it. Organizing healers is often difficult (and sometimes) a thankless job. Having a healing leader to quarterback and direct the efforts of the other healers in your raid increases the overall survivability of the raid instead of just having healers on free for all healing. I've handled healing assignments in no less than 4 different guilds and it becomes a new experience every time.
Tank Talk: Building and keeping your tanking corps, Part I
Tank Talk is WoW Insider's new raid-tanking column, promising you an exciting and educational look at the world of getting the stuffing thrashed out of you in a 10- or 25-man raid. The column will be rotated amongst Matthew Rossi (Warrior/Paladin), Adam Holisky (Warrior), Michael Gray (Paladin), and Allison Robert (Druid). Our aim is to use this column to debate and discuss class differences, raid-tanking strategies, tips, tricks, and news concerning all things meatshieldish. This week on Tank Talk I'd like to step outside the technical aspects of being a tank and focus more on the psychosocial side of things. In particular I want to look at what happens when a tank is introduced into a tanking corps of a new guild, how to keep current tanks around, and how to deal with all those old tanks that have been in the guild forever.For lack of a better phrase, I'll call the time from when a tank joining the guild until their eventual status as "god of all things tank" the life span of a tank. And perhaps the most important part of a tanks life is the new part, and it's something that I've been on both sides of the coin – the one doing the inviting, and the one being invited. Each is equally exciting. When joining a new guild I had not only the opportunity to see new content and progress to new heights, but also an opportunity to improve my skill and focus my ability to tank a mean game. And when I became class lead and eventually the guild's leader, I gained an opportunity to help new tanks become acquainted with our style of game play and watch them succeed and excel within the guild.I like to look at there being mainly fives stages of a tank's life within a guild: Recruitment, Applicant, Raider, Senior Tank, and Mentor. Let's take a look at each of these and see how people in various stages can help usher a new tank into a guild's tanking corpse while keeping the old tanks around and happy. Since this is a long subject, today I'll cover the recruitment and applicant stages in a tank's life, with the raider, senior tank, and mentor stages coming in the second installment tomorrow.
Officers betting against the raid
After the 20th Supremus kill the game can get a tad boring. There's no doubt about it. Raiders know well that you have to spice things up to keep it fun. One way to do that is to have a lively bunch of people you raid with. With them things can get "interesting" at times. The fellow officers and I in my guild have decided to make things interesting by betting on the number of people that will die during Supremus.For some reason Supremus always manages to kill a few too many people. Not too many that we can't one-shot him, but enough that it makes you scratch your head. No one dies on Illidan, Council, etc... but Supremus? Run for the hills!So to keep the fight interesting someone picks a number, say nine. That number is "the line." Myself and a couple others will take under the line, and a couple others will take over. If less then nine people die, each of us gets 20g. If more than nine die the other folks get 20g each.Is betting against the raid like this a good thing?
About the Bloggers: Krystalle Voecks
Twice a week, our writers will tell you more about themselves, and let you get to know them and the characters they play a little better. Click here to read more About the Bloggers. This week features one of our "semi-alumni" bloggers, Krystalle. (She's the short one with the pink hair above -- the rest of the above folks would be some of her many guild-mates.)What do you do for WoW Insider?These days? Some back-end smacktalking helping out where you guys don't see it. I tend to float in and out giving a hand when things are quiet, and am bringing back both Reader UI and Reader WoWspace. Before I landed my current spot as one of the leads on Massively, I was a blogger here, Guild Leader & event coordinator for It Came from the Blog. I had a lot of great times with the WoW Insider readers both there and at Dragon*Con 2007, where I got to co-host several panels with Elizabeth Harper and several other great folks. (And for anyone curious, we're doing it again at Dragon*Con this year too!) What's your main right now?She's a L70 sword-specced Troll Rogue who I primarily just raid on these days. I also have a L42 Rogue that I'm bringing up, just to see how the other (dagger) side lives. Well, that and because I can't break away from the Rogues. I just love them too much.
Will DirecTV's HD push stimulate competition?
Arguments have already begun over who will eventually reign supreme as the dominant HD provider, and while cable has had years to take advantage of their increased HD offerings compared to satellite carriers, that gap is quickly closing. DirecTV has already launched one HD-centric bird into orbit and apparently has number 11 ready to rock, and the firm's recent HD marketing campaign just might "light a fire in cable to reconsider the pace at which they invest" in HD rollouts. Of course, DirecTV's latest stunt (you know, the sixty-second countdown commercial) is full of asterisks and features a quick-lipped dame throwing in a multitude of "up to"s and "potentially"s, but what's clear is how harshly it comes down on cable. Hey, we're all for taking the gloves-off approach to getting things done, especially if we cable customers actually benefit from DirecTV's aggression.
Wii hits an unofficial eight million sold
Start your engines, fanboys. According to vgchartz.com, which is where we go to hang out when we're bored, the Wii just yesterday surpassed eight million units sold since its November 19th launch in North America. That's fast. That's really fast. Check out this graph with the option "align launches" enabled; it's staggering.So, here we go. By the end of year, Nintendo Wii sales will most likely have surpassed the Xbox 360's one-year head start to become the current generation leader, and heck, we might just "win" this thing. Who'd have thought such a turnaround was possible? And why the hell didn't we buy NTDOY stock? Dammit.Bask in the glory, guys. Most likely, one of those eight million is yours.
Preview of new Guitar Hero II co-op mode
In case you missed it on Friday, IGN posted a pre-E3 hands-on preview of Guitar Hero II's new co-op mode. It's a departure from the first game's multiplayer mode in that the two players have to depend on each other a lot more to pass each song and thereby make beautiful music together.While the old multiplayer option will still be around in the sequel, the new mode mixes distinct lead guitar and bass or rhythm parts where each player affects the other in various ways, whether by failing if either performance slips (as in DDR), sharing the same Rock Meter (with mistakes from either player resetting the score multiplier), and needing to both go vertical at the same time to activate the shared Star Power. Thankfully, different difficulty levels can be assigned to each player.The Joystiq team out in L.A. will probably find something to do until they get their sweaty paws on a guitar controller or two on the E3 show floor (maybe one of those wacky press conferences will help pass the time), but we're sure the wait to try the latest build of this rockin' series will be worth it. The seven songs available at E3 are listed below.[Thanks, murph]
