China Could Wash Away Smog With Artificial Rain Storms From Skyscrapers

Airborne pollution is a major issue in China, with local hospitals opening up ” smog clinics ” and waves of city-dwellers migrating to more rural areas to escape . While Chinese officials are pursuing “cloud seeding” as a way to control pollution, a Zhejiang University professor thinks he has a better idea: Sprinklers. Big ones. Read more…

Korean carrier to launch broadband-shaming 300Mbps LTE-Advanced network this year

Most of us in Europe and North America try not think about how much we’re getting smoked by Asia in terms of internet speeds, but here’s another reminder: residents in South Korea will soon enjoy 300Mbps wireless on the nation’s largest carrier, SK Telecom . That follows on the heels of a similar effort by CSL in Hong Kong, which achieved the same speed by combining two 20MHz LTE bands. However, the Korean carrier is using so-called LTE-Advanced 3-band carrier aggregation tech, which combines one 20MHz and two 10MHz bands. Before residents there can download the proverbial 800MB movie in 22 seconds, though, the new format will have to be standardized globally and adopted by smartphone and chip makers, a process SK said is underway. While you’re mulling that, the carrier will actually be showcasing even better 450Mbps tech in February at Mobile World Congress — so enjoy your 75Mbps max LTE, citizens.

Exhale on Your Left Foot to Avoid Side Stitches While Running

A side stitch is a common ailment while running, where you feel a sharp stabbing pain under the lower edge of the ribcage. But you might be able to avoid that simply by changing your running gait to always breathe in and out on your left foot, suggests Dr. Tim Noakes in his book The Lore Of Running . Read more…

Ball lightning has been captured on video for the first time ever

Reports of ball lightning have existed for hundreds of years, but footage of the rare phenomenon, which appears transiently in the form of a glowing sphere of electrical activity , has never been acquired outside the lab. Now, a team of Chinese researchers claims it has obtained the first recorded scientific video of ball lightning in action. Read more…

Supreme Court will hear case on police search of cell phones

On Friday, the Supreme Court said that it would weigh in on whether it is legal for police officers to search the contents of a suspect’s cell phone when they are arrested. Specifically, the high court will take up two cases from California and Massachusetts, both arising from criminal prosecutions, that have brought to question the admissibility of evidence obtained through a search of the suspect’s phone after arrest. The legal decision will come down to whether searching cell phones without a warrant is a violation of the Fourth Amendment, which prohibits unreasonable search and seizure. Earlier court precedent has allowed police officers to search all the items that a person has on them at the time of arrest. But as phones have grown to include e-mail, bank history, and location data, the potential problems with the old standards have become more apparent. A Supreme Court ruling, at least, would give some clarity as to how such situations should be handled. Reuters notes that 91 percent of Americans now have cellphones, and over half of those can connect to the Internet. Read 4 remaining paragraphs | Comments

Valve: The future of Virtual Reality is just one year away

The most exciting aspect of contemporary virtual reality is its implications. Even using Oculus VR’s early duct taped-prototype , most users immediately “get it.” You’re transported to, say, Tuscany , or an underwater exploration vehicle, or a space fighter , and that experience is enough to trigger a flood of ideas for other potential interactions — interactions that are dramatically heightened by employing a VR headset. How about deep-sea exploration in 4K? Or maybe Mars? And we’re not talking just video games, but experiences . Valve VR lead Michael Abrash detailed that notion in a recent talk: “Not only could VR rapidly evolve into a major platform, but it could actually tip the balance of the entire industry from traditional media toward computer entertainment.” Abrash believes that VR headsets so vastly outperform other interaction methods (TV, theaters, etc.) that how folks absorb media in general may be impacted by the coming wave of head-mounted displays. His concept of our potential future may be distant-sounding, but the beginning of consumer-grade, extremely polished VR headsets isn’t far off: 2015. At least that’s what Abrash and Valve are targeting as primetime for VR, and they’re laying the groundwork right now. This is a VR prototype headset from Valve Valve’s first ever game developer conference, dubbed Steam Dev Days in honor of the company’s ubiquitous digital storefront / ongoing socio-economic experiment , took place this week. Abrash gave a talk titled “What VR Could, Should, and Almost Certainly Will Be Within Two Years, ” where he detailed the current state of VR, what challenges the technology faces going foward, and when he (and Valve) believe it’ll be ready for primetime. In it, he established a baseline of standards for VR: perfect timing to lay a base given Oculus VR’s own standards for VR game development going live at nearly the same time. First, any VR headset needs to create “presence” for the person using the headset. Abrash defined presence as such: “It’s the sense of being someplace else while in virtual reality; many people feel as if they’ve been teleported. Presence is an incredibly powerful sensation, and it’s unique to VR; there’s no way to create it in any other medium.” Cliché as it is, VR headsets aim to do exactly what their name implies: simulate a new reality for the user, real enough to fool the human brain. Oculus VR CEO Brendan Iribe echoed that sentiment to us earlier this year when he said that the closer the experience is to reality, the better the experience is for the user. Sadly for us writers, “presence” — or rather the experience of using a virtual reality headset and being convinced — is incredibly hard to convey with just words. “Most people find it to be kind of magical, and we think that once people have experienced presence, they’ll want it badly, “Abrash noted during his talk. Moreover, Abrash thinks that the VR hardware available right now — including the latest Oculus Crystal Cove prototype — is still a step or two away from the specs required for true presence. He even has a list of target specs required for creating presence (which Valve has functioning in an R&D headset right now, and was shown to developers during Steam Dev Days): The Crystal Cove prototype that Valve provided support for is “a big step in the right direction” Abrash said, but still not enough to create the sense of presence he and Valve are aiming to achieve. While Valve continues R&D on virtual reality hardware — Abrash said “several” companies are working on VR headsets, though we only know of two officially creating consumer products (Oculus and GameFace Labs ). The company’s also building out Steam’s VR software support to stay ahead of the curve. That’s why SteamVR just went live (a VR version of Big Picture Mode) in beta; why VR games now have their own category in the Valve’s store; and why the company created the SteamVR API (read: it makes games play nice with the SteamVR platform). Valve’s yet to give press a chance to try its VR hardware prototype, but developers who tried it at Steam Dev Days are responding positively thus far . It apparently has specs similar to what’s detailed above, and we’re not entirely clear on whether or not it uses a camera in conjunction with the headset for positional tracking (a la the latest Rift prototype). Given Valve’s openness during Dev Days and Abrash’s assertion that Valve is open to working with any partners to push VR forward, we’re certain to hear more in the coming year(s). Abrash ended his speech with a confident, thrilling statement regarding VR: “A great VR system at a consumer price in 2015 is more than just possible – it’s sitting there waiting to happen. And it will happen, if not in 2015, then soon after. Virtual reality on the PC over the next few years may be as exciting as anything that’s ever happened in games. We’re sharing what we’ve learned with you, and we’ll continue to do so. There’s a huge amount to be learned and figured out about VR, and we certainly can’t figure it all out by ourselves; I hope that as you dive into VR, you’ll make it a two-way exchange, so together we can make VR one of the great entertainment evolutions.” Filed under: Gaming , Peripherals , Wearables , Software , HD Comments Source: Michael Abrash (PDF) , Joe Ludwig (PDF)
