Ocean waves show Earth's CO2 imbalance is greater than expected
Scientists might need to tweak their understanding of climate change in the near future. British researchers have determined that ocean waves play a considerably more important role in trapping carbon dioxide than previously thought. Their studies showed that waves breaking on the shore will absorb a large number of bubbles at depths of "at least" 3.3 feet, releasing CO2 when they dissolve into the water. That, in turn, suggests the ocean is absorbing "many times" more CO2 than under current estimates.

Is Your Gut Microbiome the Key to Health and Happiness? Amy Fleming, The Guardian You've likely heard the phrase "trust your gut" at some point in your life, but the key to being healthy and happy could actually lie in all of those organisms in your digestive system. The Guardian lays out the case for how influential your gut really is and discusses the act of "poop doping." Yes, that's a thing.
Wevr: The virtual reality studio you need to know
It's pronounced "weaver." And you might not be familiar with it now, but the LA-based virtual reality outfit is quietly positioning itself as the backbone of the industry. With one foot firmly planted in the production side of the business (the studio's recent slate includes Sports Illustrated's swimsuit issue) and the other in distribution, Wevr is primed for the impending mainstreamification of virtual reality. So when the public eventually goes gaga over VR goggles, Wevr will be right there, ready to deliver that content.
Tubular waves are, like, totally common in space
"Surfer" tube-shaped waves are created when a speedy fluid, like wind, moves over a sluggish one, like water. These so-called Kelvin-Helmholtz waves occur everywhere in the universe, as you can see in the image of Saturn's upper atmosphere, above. They also happen when solar winds strike the Earth's protective magnetosphere, and researchers now believe that they occur much more often there than we thought. Not only that, but they might cause the magnetosphere to be charged with plasma, affecting how it works to protect life on our planet from radiation.
Watch gravity waves ripple through Earth's atmosphere
You might think of gravity as an invisible force here on Earth, but that's not entirely true... if you have the right computer simulation, that is. Researchers at the National Center for Atmospheric Research have developed a climate model that shows the gravity waves in the upper atmosphere, where their amplitude is strong enough to create huge ripples. The trick is a higher-resolution model that replicates the waves at their source, and follows them on their way up. As you can see here, the results are dramatic -- gravity is virtually invisible near the surface, but it's impossible to miss when you're 60 miles up.
'Tractor beam' for water can pull boats in any direction
It can be difficult to get waterborne objects to go in the right direction -- just ask any boat captain who has had to fight waves on a choppy sea. However, researchers at the Australian National University have developed a "tractor beam" (really, a wave generator) that would make it trivial for you to float anything to its intended destination. The system creates complex 3D waves that have their own currents, letting you pull a target simply by adjusting the waves' frequencies and sizes. In fact, you can produce any flow you like; scientists in the lab made vortices on demand.

Daily iPhone App: Danger Boat is an endless runner on the waves
Most of the iOS buzz around this time last week was from the great Ridiculous Fishing, but there was another new release last week that I really liked and it's Pixelocity's Danger Boat. Vlambeer's big hit deserved all the attention it got, but Danger Boat was overlooked, I think -- it's a really well-made app as well that's simple but offers a lot of fun. "Boatpack Joyride" is probably how I'd best describe this one. It's a endless runner where you guide a boat along a watery course, trying to dodge obstacles, collect coins and use powerups while staying alive for as long as possible. Just like Halfbrick's famous endless runner, this one is well-polished and controls very well (you tilt back and forth to slide your boat around, and while I usually don't like tilt controls, this is done about as well as it can be done), and there are plenty of extras and powerups to spend with all of the coins you pick up. You can upgrade your powerups, you can buy booster items to give you extra benefits or you can buy new boats or places to race out of. There are a lot of fun details in this one, too, from the waves that kick you around to the various environments you race in while playing. Danger Boat is completely free and supported by in-app purchases, so there's no reason not to try this one. If you missed it during that Ridiculous Fishing rush, make sure you give it a good look now.
ASUS PadFone 2 review: two times is a charm for this phone-in-tablet combo
It's only been half a year since the peculiar PadFone made its much-delayed entry into select markets, and earlier this week, ASUS' launch of its second-gen phone-in-tablet brings us back to this old question: are we better off with just one mobile screen instead of two? Ask any ordinary manufacturer and the answer is likely the latter, because who doesn't want to sell more products? Similarly, carriers would likely back such manufacturers for the sake of selling more data plans, even if they admire ASUS' efforts (and they could already be selling ASUS tablets in the first place). Some folks also argue that if you have to carry the tablet module with you anyway, you might as well have two separate devices for better multitasking. It seems like there's a huge mountain to climb here, but on the flip side, ASUS' innovative differentiation does have some advantages. You only need one data plan (and no tethering required) for both form factors, you get to keep the same data in one place instead of having to duplicate them and you can pretty much instantly switch between a small screen and a large screen for the same content. Not to mention that there's also the added functionality of charging up the phone while it's sitting inside the tablet. Alas, the original PadFone and PadFone Station didn't quite hit the spot: the combined weight and bulk made it tough to justify the phone-in-tablet idea, which is why we said it's all about the PadFone 2 in our review. Let's see if ASUS has done it right this time 'round.%Gallery-168881%
Republic Wireless now issuing invites for summer beta program: is your name on the list?
Republic Wireless is now issuing the cellphone equivalent of Willy Wonka's golden tickets: an invite to its forthcoming beta. When you've been assigned a wave, you'll then be placed on a wait list, only told a week before you have to place cash on the barrel for a handset. Our tipsters have told us that the company is pitching (via a survey, of course) to hit three price points for customers, each fee buying a smartphone and the first month's service. All they could supply were the specs, so we've suggested some handsets that could fit the bill: Entry Level: $199 gets a phone from an "unknown" manufacturer with a 3.5-inch touchscreen, 600MHz CPU, 0.5GB of storage and a 5-megapixel camera -- which puts us in mind of the ZTE Libra or the iNQ Cloud Touch. Mid-range: $299 will buy a handset from a "well known" manufacturer, 3.7-inch touchscreen, 1GHz CPU, 1GB storage, 5-megapixel camera and a VGA front-facer, similar to the Galaxy U, HTC One V or Huawei Vision. Top Line: $499 gets you a 4.3-inch touchscreen phone with a 1.2Ghz dual-core CPU, 8GB storage and, weirdly, a 7-megapixel camera. We hope that last stat is a typo, since it rules out the vast majority of handsets at that level. If it was 8-megapixels, for example, we'd be thinking about phones like the Galaxy S II. We reached out to the company for more details, and were told that it's simply in a discovery phase of sorts -- it's still trying to get a better grasp on exactly what phones would be desired. Unfortunately, that means that there aren't any concrete handset decisions to be shared just yet, but we'll be sure to pass those along as soon as we find out ourselves. [Thanks, Matt]
Daily iPhone App: Magic Defenders
Magic Defenders isn't new, but it has claimed a lot of my iPhone gaming time lately. It's a tower defense game, so if you like that genre, odds are that you'll like this one. Instead of building towers, you play the game as a mage that's casting spells against waves of attackers. The game cycle has you casting spells using mana, killing attackers to earn XP, and then using that XP to upgrade your spells to kill attackers more quickly, earning more XP, and so on. It's a lot of fun and considering that the game has a few different heroes to play through and level up across three invasion episodes, there's plenty of content to explore. Blazing down enemies is very rewarding, as is learning how the various spells work together. You can slow enemies down with one spell, for example, freeze them in place with a second, and then nuke them all down with a third. The game's great on the iPad, too, but the drag-and-drop spell interface makes it easy on any iOS device. And at 99 cents on the App Store for a universal version, Magic Defenders is one of the best bargains out there that you might have missed the first time around. If you like tower defense games or ridiculously addictive game cycles, it's definitely worth the buck.
San Francisco submits permit app for wave power project
San Francisco's been mulling this one over for some time now, but at long last, the city has taken a monumental step in turning nearby waves into energy. Mayor Gavin Newsom has stated that his city has just "submitted a preliminary permit application to the federal government to develop a wave power project" off of San Fran's coast. When the project is fully operational, it could generate anywhere between 10 and 100 megawatts of energy, and it has the potential to create upwards of 100 jobs. If all goes to plan, electric power would be generated from waves that are around eight miles off the west coast of SF, and the mayor also stated that he'll be making sure that the impact on marine animals, fishing, shipping and recreational uses is minimized should he get the green light.
Magnetic signals could cure chronic insomnia
Make no mistake, there's a plethora of devices out there aimed squarely at rudely disrupting your nap, but a technique that utilizes a gaudy head wrap and magnetic pulses could make the process of conking out a whole lot easier. Apparently, scientists can use relatively standard medical equipment in order to "stimulate the brain with harmless magnetic pulses," which essentially penetrate the nerves that control a type of deep sleep called "slow-wave activity." By forcing the brain to conjure these waves, it helps trigger deep sleep in even the "most chronic insomniac," and researchers are hoping that these methods could be used to create a machine that lets weary individuals get one fabulous power nap. Until then, however, may we suggest wading through every last Intel roadmap presentation you can find without ever losing focus, as this little trick seems to work quite well in corporate settings.[Via Spluch]
Radiofrequency treatment curbs asthma attacks
Sure, there's quite a few way to circumvent the effects of asthma, but a new development coming out of McMaster University in Canada suggests that radiofrequency treatment can actually curb the amount of asthma attacks suffered by asthmatics. The device, which "uses radio waves to heat the muscle lining of patients' airways," is used to administer a trio of sessions, and while the actual root cause is still unknown, it seems to cause a reduction in the smooth muscle lining the airways, subsequently making breathing less of a chore. The probe isn't the most comfortable, however, as it must first make its way through your nose or mouth in order to reach the lung airways, after which the tip is "heated using radio waves." The procedure is known as bronchial thermoplasty, and while the funding company (Asthmatx) has yet to elicit a thumbs-up from the FDA, it could certainly become a viable alternative for asthma sufferers. It's about time these free-flying transmissions made up for the harm they've caused, eh?
Japan's earthquake warning system tested out
It's a good thing that Japan's Meteorological Agency actually had the nationwide earthquake warning system ready to rock in March, as the fiber optic system was put into use this month in an attempt to warn citizens of an imminent tsunami. Reportedly, a "huge tremor" struck and triggered the system, which allowed warnings to be beamed out en masse "within a single minute." Although the system was tested before in false alarm fashion, this was the first time it had been used in a legitimate emergency, and it beat the previous options "by around one to two minutes." Sadly, it still wasn't quick enough to save everyone from the 6.9-magnitude quake, as 170 people suffered various injuries while one individual passed away, but the statistics could've been much worse had the speedy system not kicked in at all.
Sonic fingerprinting could safeguard masterpieces, detect fakes
We know, we're suckers for cheesy art, but we give props where props are due for the well designed, masterfully engineered pieces as well. While we doubt the Digital Stag is atop any thief's list of things to swipe, there's a decent chance the Italian funeral urn Cratere dei Niobidi is. This urn spurned (ahem) a restorer and a geophysicist to envision sonic tomography as a means to protecting authentic works of art and giving museums and art buyers alike a way to spot fakes. The system works by attaching a network of sensors in and around the artifact, and when tapped with a rubber hammer, computer software can record the sonic fingerprint that will only match up with the original. Additionally, the waves could inform restorers if a segment of a structure is weaker than the eye can tell, giving them extra time to build reinforcements on ancient buildings, walls, etc. The chance of such a system ever being used outside of highly trafficked museums, however, is slim, primarily due to the $19,000 to $26,000 price range that the system falls in, not to mention the "trained staff" (read: loyal and innocent) required to run it.
Broadcast radio crosses the century mark
We'll admit, there's not a whole of gizmos invented 100 years ago that we still rely on (and bicker about) on a near-daily basis, but broadcast radio has managed to stay in our homes, cars, hearts, and complaint letters for a full century. Exactly one hundred years ago today, Reginald Fessenden fired up his transmitting station at Brant Rock, Massachusetts in order to broadcast a "brief speech," followed by an Edison phonograph recording of Handel's Largo." He also sent out a few other holiday jams and well-wishes to those spending Christmas "onboard US Navy and United Fruit Company ships equipped with Fessenden's wireless receivers." Fessenden earned more than 500 patents in his lifetime, including credit for the "radio telephone, a sonic depth finder, and submarine signaling devices." So while the FCC tries to regulate it, and we prefer the cleaner, less ad-filled satellite rendition of radio, we're still raising our glasses to a technology that's changed technology over the past hundred years, and here's to a hundred more.[Via Slashdot]
Researchers develop metamaterial with negative refractive index
We've got next-to-invisible objects and cameras with ridiculously large sensors, and thanks to a team of brilliant researchers over in Germany, now we've got "an exotic material with a negative refractive index for visible light." Gunnar Dolling and his colleagues at the University of Karlsruhe in Germany have created a metamaterial with layers of silver sandwiching a thin sliver of nonconducting magnesium fluoride on a glass sheet, and once an array of square holes were etched in, his tests showed that the "structure had a negative refractive index of -0.6 for light with a wavelength of 780-nanometers," besting the previous record of 1,400-nanometers. While the scientific babble may not mean much to you, the long and short of it is that this discovery could "lead to further breakthroughs in invisibility cloaks, which could hide objects from the human eye" and make escaping your troubles quite a bit easier. Moreover, the technology could be used in "superlenses" to see details "finer than the wavelength of visible light," but Dolling is reportedly more interested in studying the effects of his discovery than attempting to build any mystical devices, which is probably for the good of mankind, anyway.[Via Slashdot]
Human WiFi sniffer is every geek's dream woman
Alright Europe, things were dubious enough when you erased children's rights to wireless access after believing that the radiation a good chunk of internet users have been subjecting themselves to for years is suddenly cause for concern, but this is a bit much. Undoubtedly crossing the line between caution and hypochondria, a British author now claims that "electromagnetic waves" emitted by the WiFi setup in her crib "left her feeling exhausted, nauseous and sleepless." Moreover, she even states that she is so sensitive to 802.11 radiation that "she can instantly tell whether it is installed in a particular room." Aside from the above symptoms, Kate Figes (pictured) described a feeling of being "prodded by 1,000 fingers" when entering a room laced in WiFi, which presumably garnered all sorts of (understandable) skepticism. Sure, we could understand the backlash associated with cellphone signals causing all sorts of turmoil in your noggin, but if WiFi is the true brain cell killer, we're all pretty much on death row.[Via TechDirt]
