Video of protein movement within a neuron shows how our brains renew themselves

A rare look at protein movement within a neuron shows how our brains renew themselves

If, like us, you spend most of your time wondering exactly what’s going on in other people’s heads, then this video is for you. Okay, so it might not reveal the reason why that jerk cut you off at the junction, or why that co-worder didn’t show up to your date exactly, rather, it’s a little more literal than that. This is video footage of proteins moving within a single neuron. The USC researchers were able to capture this video by using bioluminescent proteins from a jellyfish to visually track their movement. Not only is this mind-boggling to the layperson (just think how small these things are) it’s also mind-revealing. By that, we mean it gives scientists an opportunity to observe how these tiny, yet vital, cerebral elements restore themselves. Which, when you’re constantly worried about the amount of grey matter you were blessed with in the first place, can only be a good thing.

Harvard makes distortion-free lens from gold and silicon, aims for the perfect image (or signal)

Harvard makes distortionfree lenses from gold and silicon, aims for the perfect image or signal

Imaging has been defined by glass lenses for centuries, and even fiber optics haven’t entirely escaped the material’s clutch. Harvard’s School of Engineering and Applied Sciences might have just found a way to buck those old (and not-so-old) traditions. A new 60-nanometer thick silicon lens, layered with legions of gold nanoantennas, can catch and refocus light without the distortion or other artifacts that come with having to use the thick, curved pieces of glass we’re used to — it’s so accurate that it nearly challenges the laws of diffraction. The lens isn’t trapped to bending one slice of the light spectrum, either. It can range from near-infrared to terahertz ranges, suiting it both to photography and to shuttling data. We don’t know what obstacles might be in the way to production, which leads us to think that we won’t be finding a gold-and-silicon lens attached to a camera or inside a network connection anytime soon. If the technology holds up under scrutiny, though, it could ultimtately spare us from the big, complicated optics we often need to get just the right shot.

Genius bonobo chimp creates stone tools like early hominids

You may not be familiar with the word bonobo, but I’d wager most of us know what a chimpanzee is. A bonobo is a member of the chimpanzee family and was previously called the dwarf or gracile chimpanzee. Confusion on the name aside, a genius bonobo named Kanzi has begun making his own stone tools similar to tools early humans made.

Researcher Eviatar Nevo from the University of Haifa in Israel and colleagues have been presenting Kanzi with problems that the animal has solved. Kanzi is a 30-year-old male bonobo chimp, and he has made some sophisticated and interesting solutions to problems presented to him. The researchers gave Kanzi food sealed inside of a log that mimics bone marrow inside of a long bone.

Another male companion chip studied was also presented with the same problem. The second chimp tried to retrieve the faux marrow from inside the log a handful of times and eventually resorted to smashing the log on the ground. Kanzi on the other hand took a longer and more sophisticated approach.

He inserted sticks into the seams on the log to try to split it, threw projectiles that it, and used stone flints, choppers, drills, and scrapers. Kanzi’s sophisticated approach allowed him to get food out of 24 logs while his not as intelligent companion only managed to get food out of two logs. According to the researchers, the most remarkable thing about the tools Kanzi created was their resemblance to the tools created by early hominids. It’s worth noting that researchers have previously taught both chimps to knap flint flakes. However, Kanzi’s companion was unable to put his tool-making prowess to use in retrieving the food from log.

AM General selected for $64.5 million military contract for BRV-O

The vehicle that the military uses for driving soldiers into combat and general getting around has been the Humvee for a long time. This vehicle has been used for many purposes, and the military is looking to replace this workhorse vehicle with a new, blast resistant vehicle to help protect soldiers. The Humvee is produced by AM General.

The company has announced that it has been granted a contract in the US military’s search for a new Joint Light Tactical Vehicle worth $64.5 million. The multimillion-dollar contract is for Engineering, Manufacturing, and Development phase. Under the contract AM General will produce and deliver 22 prototype Blast Resistant Vehicle- Off road known as BRV-O for short.

I suspect these vehicles, if adopted in the military, will be called Bravo. The vehicles delivered under the new contract will be delivered to the government for testing. AM General says that the BRV-O is based on more than 10 years of investment in research, development, and testing for the next-generation vehicle. Prototype test vehicles have already racked up 300,000 operational test miles.

The vehicle has proven to be highly reliable and maintainable during testing. One key feature of the BRV-O is modular armor and a crew capsule that has proven to be effective at protecting soldiers during government-supervised blast testing. Other features of the vehicle include a fuel-efficient high-performance engine, self-leveling suspension, a C4ISR backbone with open standard network architecture and clustered super-computing power, and other advanced components.

Aerofex hover bike is the coolest vehicle ever

When I was a kid, I was a cub scout and the only thing I remember that was cool from the experience was the magazine that came with the membership. The coolest thing about that magazine wasn’t the articles or puzzles. The cool part was the ads in the back for things like x-ray glasses and this awesome DIY hover vehicle powered by a vacuum cleaner motor. Sadly, my mother would never let me take her vacuum apart to build one, but if Aerofex is successful with its hover vehicle, I won’t need a vacuum.

The Aerofex hover vehicle looks similar to the hover bike we talked about last year. The main difference is rather than one geek working on the project, Aerofex is a company that hopes to commercialize the technology. One of the most interesting parts is that Aerofex has solved some of the instability issues plaguing similar earlier designs and says operation of the vehicle is so simple no pilot training is required.

Rather than having wheels like a normal motorcycle, the Aerofex vehicle has a pair of ducted rotors. The company has addressed stability issues in the design using a mechanical system with two control bars located at the rider’s knee level. Those control bars allow the vehicle to respond to the pilots leaning movements and natural sense of balance.

Control of the bike is handled mechanically with no electronics or artificial intelligence flight software required. That should make the bike more robust, cheaper to purchase and operate, and safer. Aerofex has crushed my dreams somewhat because the company doesn’t plan to develop and sell versions design for people to ride to start with. The company envisions the vehicle as a test platform for new unmanned drones.

FCC report says 19 million Americans still without broadband access

FCC's Broadband

The FCC believes that 19 million Americans don’t have access to broadband, defined as internet access at a speed of 4 megabits per second or more. Understandably, rural areas are the worst hit, with 14.5 million out in the sticks without access, with areas like West Virginia lacking coverage for 45.9 percent of its population. It’s not limited to the wide open spaces of states like Montana (16.7 percent) however, even tech-heavy states like California lack access for 35 percent of its denizens. The commission’s Connect America fund is charged with closing this gap, and has already awarded CenturyLink $35 million to connect 45,000 homes in under-served areas as part of a plan to help seven million more people get online by 2018.

Autonomous Wave Glider bot launched to track sharks, beam real-time data to your iPhone and iPad

Autonomous Wave Glider bot launched to track sharks, beam real-time data to your iPhone and iPad

When they’re not breaking world records, fuel-hating Wave Glider seabots like to indulge in other hobbies, like shark tracking. One of the vessels has just been launched off the coast near San Francisco (vid after the break), adding a mobile worker to the existing local network of buoy-mounted receivers. They monitor the movements of electronically tagged sea life, including the fearsome Great White, picking up signals within a 1,000-foot range while researchers from Stanford University analyze the data from the safety of the shore. Better still, the free Shark Net iOS app gives anyone the chance to track these things, and activity should increase as the monitoring network (hopefully) expands along the west coast and more bots are introduced. You didn’t think the world’s fascination sharks was limited to only a single single week, did you?

Georgia Tech develops self-charging battery that marches to the owner’s beat

Georgia Tech develops selfcharging battery with laws of physics still intact

One of the last times we saw the concept of a self-recharging battery, it was part of a high-minded Nokia patent whose ideas still haven’t seen the light of day. Researchers at Georgia Tech are more inclined to put theory into practice. Starting from a regular lithium-ion coin battery, the team has replaced the usual divider between electrodes with a polyvinylidene difluoride film whose piezoelectric nature produces a charging action inside that gap through just a little pressure, with no outside voltage required to make the magic happen. The developers have even thumbed their noses at skeptics by very literally walking the walk — slipping the test battery under a shoe sole gives it a proper dose of energy with every footstep. At this stage, the challenge mostly involves ramping up the maximum power through upgrades such as more squeezable piezoelectrics. Georgia Tech hasn’t progressed so far as to have production plans in mind; it’s nonetheless close enough that we could see future forms of wearable computing that rarely need an electrical pick-me-up.

Harvard stores 704TB in a gram of DNA, may have us shopping for organically-grown storage (video)

Harvard stores 704TB in a gram of DNA, may have us shopping for organicallygrown storage video

Early research has had DNA making circuits and little factories. We haven’t really seen DNA used as a storage medium, however, and it’s evident we’ve been missing out. A Harvard team led by George Church, Sriram Kosuri and Yuan Gao can stuff 96 bits into a DNA strand by treating each base (A, C, G, T) as though it’s a binary value. The genetic sequence is then synthesized by a microfluidic chip that matches up that sequence with its position in a relevant data set, even when all the DNA strands are out of order. The technique doesn’t sound like much on its own, but the microscopic size amounts to a gigantic amount of information at a scale we can see: about 704TB of data fits into a cubic millimeter, or more than you’d get out of a few hundred hard drives. Caveats? The processing time is currently too slow for time-sensitive content, and cells with living DNA would destroy the strands too quickly to make them viable for anything more than just transfers. All the same, such density and a lifespan of eons could have us turning to DNA storage not just for personal backups, but for backing up humanity’s collective knowledge. We’re less ambitious — we’d most like to know if we’ll be buying organic hard drives alongside the fair trade coffee and locally-sourced fruit.
