Harvard's noodly robot fingers are great at grabbing jellyfish
Robots can be a bit heavy-handed. Their forceful grip might not be a problem when they're moving boxes in a warehouse, but they can damage fragile marine creatures like jellyfish. Researchers may have a solution. They've created a robotic hand with a squishy grabber and a gentle grip that uses "fettuccini-like silicone fingers" to catch and release fragile, gelatinous jellyfish.
The latest 'Fortnite' weapon lets you drop heavy stuff on opponents’ heads
Epic has another way to battle Fortnite's hated newcomer, giant mechs. Sure, the two-player B.R.U.T.E. mechs have 1,000 health, can travel hundreds of in-game meters in a few seconds and can blast you with rockets or stomp on you. But now, regular players can strike back by dropping something heavy -- like a dinosaur -- on giant mechs and other opponents.
'Overwatch' test lets you pick and queue for a specific hero class
Players have been asking for it for years and finally, it's arrived: Blizzard is introducing Role Queue to Overwatch. From today, players in the PTR will be able to beta test a feature that allows them to choose the role they want to play -- tank, support or damage -- before a match begins. Usually this decision-making happens in a fairly fraught 40 seconds before a match starts, as everyone selects their heroes and responds to other players' role choices -- so it's not uncommon to feel bummed out as a team comes together.
This is why you don't look directly at a solar eclipse
Remember all that talk about eclipse glasses ahead of the full solar eclipse in August? Remember NASA repeatedly letting everyone know how important those glasses were for eye safety? Do you remember how many times you heard someone say to not under any circumstances look directly at the sun during the eclipse? Well despite all of those persistent warnings, some people still did just that and a new paper published today in JAMA Ophthalmology shows that just six seconds of unprotected viewing can cause permanent damage.
This color-changing polymer warns of tiny damage you can't see
Tiny cracks can actually be a big deal when they're forming inside parts of your car or, say, a metal shell that's flying into space. University of Illinois research, led by Professors Nancy Sottos and Scott White, has lead to a polymer coating that could be an important early warning system, making it easier to find trouble spots before something really bad happens. When cracks form in the polymer, micro-beads also crack open, causing a chemical reaction that visibly highlights the damage with color. The capsules are pH sensitive, meaning any damage will cause a strong color change, from yellow to red, with no additional chemicals needed. Deeper, more serious, scratches and damage will create stronger hues of red as more capsules break open.
Researchers are helping robots avoid expensive face plants
Why are robot tumbles comedy gold? Unlike humans, they make no effort to protect themselves, resulting in flailing, extra hard falls (bottom). But the high-g impacts are hell on the extremely expensive, often one-of-a-kind machines, so researchers from Georgia tech developed algorithms to give them some sense of self-preservation. They made them copy exactly what we do instinctively -- stick out a limb to break the fall. "(That way), every time you make contact with the ground, some of the energy is dissipated," said Georgia Tech professor Karen Liu.
Watch this little robot learn to walk after taking damage
Robots are getting pretty good at carrying on after taking a knock, but what if they lose a limb? Scientists from the US and France have given a six-legged 'bot the smarts to keep going even if two of its legs are disabled by, say, a Sarah Connor shotgun blast. The team created and then rated a number of simulations for how its robot could keep moving forward despite losing a leg or two. Once that information was programmed into the robot, it was able to rapidly evaluate the options and use the one that worked best in the real world.
Water isn't always the kiss of death for an iPhone
Water and technology don't mix. If you drop your iPhone in a lake, pond, toilet, or martini, there's a fantastic chance it will end up being completely destroyed. Many of the little electrical bits inside the device don't take kindly to be drenched, especially if it leads to a short. However, as Rob Griffiths of Macworld discovered, sometimes all is not lost. His story on the premature death, rescue, autopsy, and unlikely resurrection of his iPhone 5 is definitely worth a read in its entirety, but if you're too pressed for time, at least take this small tidbit of information with you: Complete disassembly and a thorough blasting with compressed air can be the magic touch. Also, it helps if you drop your phone took a bath in fresh water, as opposed to the ocean. Saltwater is infinitely more deadly for an unprotected smartphone, so keep that in mind.

Interview: Technical Game Designer Chadd "Celestalon" Nervig talks Warlords of Draenor
I was lucky enough to head over to Blizzard Campus this week to talk to Technical Game Designer Chadd "Celestalon" Nervig. Chadd is a huge part of the class design team, key to a lot of the changes we saw in the recent Warlords of Draenor patch notes, which is just what we discussed. We were also joined by Senior Community Representatives Zarhym and Lore. You can also find a much-abbreviated summary on Wowhead. Olivia: First up, is there anything you really wanted to clarify and get out there? Celestalon: I've tweeted about pretty much everything. This was the first version of the patch notes, there have been more changes since then, those patch notes are about a week old or so? Zarhym: Yeah it's like, tons of changes. [Rygarius] said he had a huge list of changes. Celestalon: There's another five thousand words that aren't up there yet, which [Rygarius] is working on now. There have been different amounts of patch notes released for different classes. Paladins have been complaining that they haven't got enough, rogues have been really happy that not much has changed. Is it safe to assume there's more to come? This is just step one? There's definitely more coming. Like, for example, paladins had relatively few patch notes, and a lot of that is we were relatively happy with how things played out, at least for ret and prot, with the exception of a few things we can solve with tuning – changing numbers. So a lot of what you see in the patch notes now is what we call design changes, so the mechanics that we want to change so we can get to some design that we like.
Liquipel debuts Skins to protect your phone from physical damage
We've highly regarded Liquipel for its clever "watersafe" nanocoating, which has been known to give phones the same protection from liquids and other materials as an IPX7-certified device. That doesn't prevent physical damage from occurring, however, so the company's announcing Skins, its answer to drops, hammers and plenty of other things that cause blunt force trauma. Even better, Liquipel claims that it requires a three-step dry installation process that doesn't involve squeegees, water bottles or bubbles; once you're done, you'll enjoy a "literal shock absorber" for your trouble. Skins for the iPhone 4S and 5 should be available today for under $20 on the company's site, while the Samsung Galaxy S4 will soon follow (it's currently listed as "out of stock") and other models will be ready in the coming months. Check out the video and press release after the break.
Parenting Tip: You've got a broken iOS device, now what?
Last week, our parenting tip provided you with advice about protecting your iPhone or iPad from a damaging fall. Though helpful, these tips are not foolproof, and there may be a time when you find yourself staring at a broken iOS device. My iPad 2, which was housed in a rugged case, suffered this fate recently when the screen cracked after my five-year-old stepped on it. A week later my iPad 1 screen cracked when it landed corner first on the floor. Once you have come to terms with the harsh reality that your iOS device is broken, you then need to decide what you are going to do with it. Read on for some suggestions that'll help you decide whether you should fix your device or replace it. We'll also include some tips on how to repair, replace or sell a broken device. The First Question: Repair or Replace? The first question you must ask yourself is whether you want to repair your device or replace it. You'll have to weigh factors like the cost of the repair, the cost of a replacement and the age of the device. It is hard to justify spending $200 to fix an iPad 1 when you can grab a new iPad mini for a little over $300. I've crunched these numbers and concluded that, in general, it's cost effective to fix a newer, more expensive device and dump an older device that is slower and may not run the latest version of iOS. This isn't a hard and fast rule as there are times you may want to keep the older device because it has data on it that you don't want to lose. This happened to me earlier this year when my original iPad stopped charging. It cost me $50 in parts and my own labor to fix the three-year-old tablet, but I didn't want to lose the photos stored on it. Another factor to consider is the warranty status of the device. You can't add an accidental damage warranty to a used device that you buy off of Craigslist, but you can add a plan to a new device within the first 30 days. If you think your children are prone to breaking devices, you may want to cut your loss on the the old device and replace it with a new one that has an AppleCare+ or SquareTrade warranty. What Are Your Options for Repair? If you decide to fix your iPhone or iPad, the least expensive option to get your device operational again is to fix it yourself. Many replacement parts are inexpensive and can be purchased online from places like iFixit. iFixit also has a great set of tutorials for the iPhone and iPad that'll walk you through the repair process. YouTube is another good source for repair videos, especially if you like to watch the repair before you actually start doing it. Depending on what is wrong with your device and your skill level, self repair can be a daunting task, though. I'm pretty handy when it comes to devices and tried to fix the charging port on my iPad -- it didn't turn out as well as I had hoped. I was able to replace the charging cable, but getting the display off the iPad was much more difficult than I expected. I ended up damaging the soft aluminum shell of the iPad when I pried off the screen and likely ruined any reasonable chance to resell the device. If you prefer not to crack open your iPhone or iPad, then you can travel down to your local Apple Store and get a repair quote. Depending on the problem, Apple may have to send out the device for repair. There is also a chance Apple may not be able to fix the device, as was the case with my broken charging port. It is worth noting that Apple Stores are supposedly adding tools and supplemental training so Geniuses can repair a broken iPhone screen and other common ailments right in the store. Besides Apple, there are also third-party companies like IFixYourI and eBay sellers that'll repair your iOS device for a fee. Prices vary, but most places charge just under a $100 to repair a broken screen, around $70 to replace a headphone jack and about $60 to replace a power button. Most of these services require you to send in your device for repair, and they will send it back to you when it is fixed. If you have local computer repair shops, check with them, too, as many offer repair services for the iPad and iPhone. Repairing broken hardware like a screen or a button is pretty straightforward -- buy the broken part and replace it. Water damage, though, is handled a bit differently as it can affect multiple parts of your device and critical components like the motherboard. Most repair companies will try to fix a water damaged device, but they won't charge you when you send in your device. The technicians will examine the device and determine if they can fix it before talking to you about repair costs. Be prepared as water damage can be expensive to fix. What if You Want to Replace Your Device? If you want to replace your device instead of repair it, you have several options to buy new or used gear. The easiest and cheapest way to get a replacement device is to exercise the replacement clause on your warranty. If you purchased an AppleCare+ warranty for your iPhone or iPad, then you can go to an Apple Store and get a replacement for $50. You are allowed two replacements while the plan is in effect. SquareTrade offers a similar replacement plan that includes a $50 deductible for each replacement. With SquareTrade, you can get up to four replacements over the life of the plan. Apple also offers an Out-of-Warranty Service option that lets you trade-in your broken device and purchase a replacement device at a reduced cost. Accidental damage is covered by this service, with the exception of catastrophic damage like your iPad being cut in half. Apple will replace your iPad with a similar, new or like new iPad model for a fee. The cost varies by device with an iPad mini costing $219, an iPad 3/4 costing $299 and an iPad 1/2 costing $249 to replace. Similar terms exist for the iPhone with a replacement cost of $229 for an iPhone 5, $199 for an iPhone 4S and $149 for an iPhone 4 or older model device. If you have a newer model iPad or iPhone without an accidental damage warranty, this replacement option is less expensive than buying a brand new device. You can also choose to buy a replacement device on eBay or Craigslist. You will save some cash by purchasing from a third-party seller, but you run the risk of buying a stolen device or one that has a hidden problem. If you want to buy a replacement and don't mind spending the money, I would recommend buying new from Apple or another authorized reseller. With a new device, you can purchase a warranty with accidental damage coverage and not have to worry about losing your $500 investment the next time your device hits the pavement. Where to Sell Your Broken iOS Device? If you decided to buy a new iOS device, you likely still have the broken one sitting on your shelf, collecting dust. Don't let it just sit there and decay, do something with it. You can either recycle it through Apple's recycle program or sell it to someone who can fix it. Resellers like Gazelle and uSell are two of the few services that'll pay you money for your broken devices. Prices are good but not great. Gazelle will pay you $125 for a broken 16GB iPhone 5, while uSell located a buyer who would pay $160. Apple also will take your broken device, but it won't pay you for it. Amazon doesn't even have an option for a broken device. Last but not least, you can always sell your broken iOS device on eBay or Craigslist. You may get more money going this route, but you will have to take the time to accurately describe the damage to your device so you won't disappoint your buyers.
Pro Tip: Damage meters don't tell the whole story
Some people /ignore others in random raids or dungeons for language or bad play. I add to my instant /ignore list those who spam the meters in raid chat. Anyone who cares about whose bar is the longest is already measuring on their own screen. Not only is the reporter almost always on the top (and conveniently never reports when s/he is below), but displaying the damage done for a fight to the same raid who's on the meter is just pure epeen spill. Asking for a damage meter is just laziness (or, in rare cases, a really crappy computer paired with a log-intensive fight). Let's not forget that problem of boiling a player down to a single number. All three roles of the holy triad have a complex set of abilities for every encounter.
Where do most iPhone accidents happen?
The most common place to destroy an iPhone is not in your car or even the bathroom. According to a survey from Squaretrade, most fatal iPhone accidents (21 percent) happen in the kitchen, with the living room (18 percent) and bathroom (16 percent) following closely behind. Surprisingly, only 9 percent of damaged phones went for a swim in the toilet. The majority of accidents (69 percent) are caused by the owner and happen inside the home (51 percent). The survey also showed that water is the leader when it comes to liquid damage, with soda, beer and coffee/tea rounding out the list. Have you killed an iPhone? Share your tale of woe with us in the comments. [Via CNET]
Dungeons and you - a guide to basic etiquette
I am generally a tank, and therefore when I run heroics I tank them. This is not always the case. If I want DPS gear, I queue as DPS because it's only fair to perform the role you intend to gear up. This results in me ending up switching to tank after a previous tank has left, or the group has wiped a few times, about half the time I sign up to DPS. This is intensely frustrating to me, because I don't like having to switch and end up seeing the gear I came for, and signed up for, going to someone else because I'm tanking. I also don't like tanking after waiting in a queue for twenty minutes. Therefore, this is a basics guide to dungeon running that covers a few things all groups should know, because I'm seeing a lot of groups that don't seem to know them. Five man dungeons are all about personal responsibility in the Mists of Pandaria era - you need to help keep yourself alive by making smart decisions.
RIFT reveals the Tactician, master of flamethrowers
RIFT has been updated with new areas and content since launch, but the upcoming Storm Legion expansion is set to seriously kick things up a notch. As if tripling the size of the game world weren't enough, the expansion will raise the level cap and add a new technology-based soul to each of the game's core classes. The battle-mage style Harbinger soul was revealed at Gamescom 2012 in August, followed by the Tempest, and data from the test server hinted that the remaining pair might be named Defiler and Tactician. Last night Trion Worlds confirmed our suspicions by revealing the new Rogue Tactician soul to livestream viewers. The Tactician uses a magical weapon that's part flamethrower and part fire extinguisher, able to deal incredible area-effect elemental damage to enemies but actually heal allies. Players using the soul can also place small devices called Cores on the ground to provide area-effect healing, buffs, and additional damage. The flamethrower-like weapon is directionally aimed and can be channelled while the player is moving, so clever positioning is required to get the most out of this unique soul.
How to choose between the same pets, but different stats
Something I was surprised to notice when I began collecting battle pets was that the stats were not always consistent within the same pet type. While Mr. Wiggles is always Mr. Wiggles, a rare Mouse does not necessarily have the same stats as another rare Mouse. The inconsistency of stats applies to both purchased pets, like Undercity Cockroaches, as well as wild pets, such as a Cheetah Cub. (Have you killed a cheetah so that you could capture her baby? I have. We are bad people.) At this time, many of us have more than three of quite a few battle pets. Extra quest pets, like Winter's Little Helper, can just be caged and sold (when cageable, of course), since they all have the same stats. but how do you choose which purchased pet you should keep? And what about the wild pets? I'll show you my favorite stat, and you can show me yours.
Curiosity rover flaunts its battle scar, wind sensor is bruised (but not broken)
You can't win 'em all. Such is the case with the Curiosity rover, anyway, as diagnostics have revealed that its wind sensors have sustained damage. NASA engineers aren't fully sure what caused this minor setback to the otherwise successful landing, but hypothesize that stones might've been kicked up during the rocket-powered landing, which then struck the sensor's wiring. Fortunately, there's already someone on the job, as Javier Gomez-Elvira is investigating the damage with the intent of restoring the lost functionality. Another NASA scientist, Ashwin Vasavada, believes the issue is rather minor: "It degrades our ability to detect wind speed and direction when the wind is blowing from a particular direction, but we think we can work around that." The broken instrument was initially discovered as part of NASA's routine power-cycling of all instrumentation, so as to determine an overall bill of health for the rover. Now that Curiosity has earned its battle scars, it can hold its head high during its journey to Glenelg and Mount Sharp.
