Caltech invention focuses light like never before, could bolster nextgen communication platforms

Light. What is it? What isn’t it? Such are the questions left to the experts at Caltech, which have just concocted a new device that can focus light to a point just a few nanometers wide. That kind of precision has never been done at scale, and the university is hoping that the invention could help “pave the way for the next-generation of communication, computing, and even imaging technology.”

In lay terms, it could allow increased bandwidth for fiber optics, and since it’s built on-chip, integration with existing doodads shouldn’t be too much of a hassle. Previous on-chip nanofocusing devices were only able to focus light into a narrow line, making them inefficient, whereas Caltech’s contraption can be focused in three dimensions, producing a point a few nanometers across, and using half of the light that’s sent through. Hyuck Choo seems to think that it can be put to use in short order in the medical field, but it remains to be seen if we’ll see this in the next wave of Google Fiber rollouts. But hey, a lowly DSL user can hope, right?

Through careful breeding they’ve managed to produce a sweet pineapple that also tastes like coconut, reducing future Pina Colada recipes to just two ingredients. More »

NASA accidentally improves weather forecasting with lunar dust-measuring lasers

NASA accidentally improves weather forecasting with lunar dust-measuring lasers

Anyone that’s ever tried to plan an outdoor activity in advance knows that weather forecasting is not an exact science, but the perpetual sky-watchers at NASA may have inadvertently found a way to improve these guesstimations. They have been testing a laser system for measuring lunar dust and soil kicked up by rocket exhausts, and while using precipitation as a substitute to calibrate the laser, they found they could measure the average size of raindrops passing through it. This value is estimated in current forecasting models, so plugging in some accurate numbers should make those predictions more reliable.

The original mission hasn’t been forgotten, though. Particles whipped up by landing rockets on the moon’s surface could damage what was left behind by the Apollo missions, ruining its scientific and historic value. One of the laser sensors may find its way onto a craft vying for Google’s X Prize, with the results used to determine where vessels can touch down whilst keeping a safe distance from Apollo landing sites. Although an accidental discovery, the system’s other potential career in weather forecasting will also continue to be explored. Now, if only there was a way to make it rain and speed up the testing.

Researchers to bore through 3km of Antarctic ice, seek organisms isolated for 100K years

UK researchers to bore through 3km of Antarctic ice with hot water jet, seek life

UK researchers are ready to see if life can exist in one of the harshest environments on the planet: Lake Ellsworth in the Antarctic, 3 km (2 miles) below a glacier. They’ll try to drill through the ice by December 12th using a high pressure sterile water jet heated to 90 degrees Celsius (194 Fahrenheit) and sterilize the patch of lake with intense ultraviolet light before attempting to retrieve a sample. If any organisms can be found, they’ll have evolved in isolation for at least 100,000 years, according to team, and probably even much longer. That could help scientists understand more about how life evolves on this planet, and possibly elsewhere — like iced-over oceans on Europa, Jupiter’s moon, or other harsh planetary environments. It’ll be the deepest borehole ever made with hot water, and the team will have a mere 24 hours to sterilize the lake entry and collect samples before it refreezes. When asked which part of the tricky experiment worried him the most, lead scientist Chris Hill replied, “everything.” For a video tour of the drill site, head below the break.

Flicker-Free Silent Panel Lights Will Bring Relief To Office Drones Everywhere

Physicists at Wake Forest University have developed a revolutionary lighting alternative that promises to be at least twice as efficient as fluorescent bulbs without the notorious buzzing and flicker plaguing offices across the country. The new bulbs are also free of toxic mercury vapor, shatterproof, and promise to solve world hunger. (Ok that last one might be stretching things.) More »

Utah State University unveils public transit bus with inductive charging

Researchers at Utah State University in Logan, UT have figured out a way to bring inductive charging to public transportation with an electric bus that’s capable of recharging itself at each bus stop. Charging plates under the the pavement at each stop charge up the battery inside the bus, and while the plates and the bus have to be lined up somewhat in order to charge, they don’t need to be perfectly lined up every time in order to juice up.

A prototype of the bus, called the Aggie Bus (named after the school’s nickname) is already on the road being tested as we speak. The folks behind the project plain to have a commercial vehicle on the market soon, but no specific timeline was given. The bus uses the same wireless charging principle as an electric toothbrush or a wireless smartphone charger. The only difference is that it’s optimized for a vehicle.

Induction charging, in this specific instance, allows for smaller batteries on the electric bus, which frees up room for more interior space, as well as reduces downtime and allows for lower battery costs. Utah State University will be the first college campus in the US to debut such a bus sometime in 2013.

Of course, this isn’t the first time we’ve heard of wireless charging used in vehicles. Last month, Qualcomm kicked off a new wireless charging trial called “Halo” that’s all about testing different ways to bring inductive charging to everyday driving. Unlike current electric vehicles, which have to sit overnight to recharge, Qualcomm’s initiative plans to have the highway itself be the charging pad. Of course, we won’t see this kind of technology for a few more years, and it’ll still be in the slow rollout phase by then.

Americans spend over 2 billion hours on social media per month

It’s really not a surprise when you’re told that people spend a lot of time on social media. We all know that Facebook has over a billion users, and that all these statistics that get thrown around of how many photos users share on social networking sites are just a fancy way of saying, “people are using social media.” However, it turns out that Americans are collectively spending over two billion hours on social media, every month.

In its annual Social Media Report, Nielsen says that Americans spent a collective 121 billion minutes on social media websites in July alone, which is up from 88 billion the year before. 121 billion minutes equates to just over 230,000 years, which means if we split that time equally amongst every American, that would be about 13 minutes per person per day.

Of course, not everyone in America uses social media — Facebook alone has around 150 million active users in the US according to the report, and there are a total of around 212 million Americans using social media as we speak, compared to the current total US population of 312 million. It’s also very possible that a lot of social media accounts are probably duplicates or multiple accounts for one person. So, more realistically, people are probably spending a lot more than just 13 minutes surfing Facebook and Twitter every day. Specifically, if we took those 121 billion minutes and split them equally amongst the 212 million social media users in the US, that would be approximately 19 minutes per person per day, on average.

These are just rough estimates obviously, and not every single social media user only spends 19 minutes per day browsing the sites, but the total 121 billion minutes makes sense no doubt. Furthermore, Nielsen reported that, on average, users spend roughly 20% of their time online on a computer browsing social media, while on mobile devices, users spend around 30% of their time surfing the likes of Facebook, Twitter, and Google+ on their tiny screens.
