You know that terrible feeling in your gut when you’ve eaten something you shouldn’t have? Well imagine having a Roomba small enough to swallow, one that could clean up that mess inside you. That’s not exactly what DARPA had in mind when it funded the creation of this penny-sized vacuum , although it certainly should have been. Read more…
Can you identify Beethoven’s Sonata No. 9 after hearing a mere three notes? Probably not, but a group of computer scientists and music scholars have built a machine that can do just that. The team — composed of Pablo Rodriguez Zivic, Favio Shifres and Guillermo Cecchi — has developed an algorithm capable of identifying patterns across distinct periods of Western music based on semi-tones and notes. Beyond its musical application, the machine represents tantalizing possibilities for research into disorders that affect speech. For example, current mechanical methods are already capable of recognizing vocal patterns common in the early stages of Parkinson’s , but the trio hopes to utilize their project for even earlier detection. Such an algorithm could also be instrumental in identifying psychiatric conditions that impact the speech centers of the brain. Unfortunately, the lack of a comprehensive database of different types of speech patterns stands in the way of wider implementation. Even so, the team is hopeful that verbal tests might someday be used in place of invasive diagnostic procedures to identify certain illnesses.

Researchers build machine that identifies music after hearing only three notes
The US military’s dabbled with full-on robotic suits in the past, but it’s now looking at a less convoluted , more energy-efficient approach. A project called Warrior Web from DARPA aims to enhance soldier carrying capacity and minimize injuries by distributing loads better, providing better joint support and “reapply(ing) energy to enhance motion.” Such a suit would be equipped with sensors to detect forces, and be able to fit beneath existing uniforms while consuming only 100W of juice. The US Army has nearly completed five months of prototype testing using a multi-camera motion capture system (see the video after the break) to develop critical tech. The next step will be to design and fabricate a suit ready for real-world testing, which should happen in the fall — assuming the program keeps its footing.

Apple product sales are flattening out a bit compared to last year, save for iPads. Casey Johnston Apple boosted its research and development spending by 33 percent in the second quarter of 2013 compared to the same period last year, according to a quarterly report filed with the Securities Exchange Commission. If the rate of spending continues, Apple could drop over $4 billion on R&D this fiscal year. During the quarter ending March 30, 2013, Apple spent $1.119 billion on R&D, compared to $841 million from a year ago. In the first six months of its fiscal year, Apple has spent $2.129 billion total on R&D, while it spent only $1.599 billion last year. Apple stated that the spending for the quarter was up 33 percent due to “an increase in headcount” and “expanded R&D activities.” The statement went on to say that the “focused investments” in R&D are “directly related to timely development of new and enhanced products that are central to the Company’s core business strategy. As such, the Company expects to make further investments in R&D to remain competitive.” Read 1 remaining paragraphs | Comments

Shortly after the Kinect SDK first launched , it spawned a number of inspired efforts from researchers to make it do more than just track your body. Microsoft Research finally seems to be catching up to its own tech, as it just flaunted a recent project that allows fine-tuned gesture control, thanks to a newly developed talent for the motion sensing device to read whether your hand is open or closed. That let the team simulate multitouch-like capability on a PC as they air-painted basic images and manipulated Bing maps by varying their hand states. The hardware used doesn’t appear to be stock, so whether such new capability entails a rumored new version of the Kinect that may or may not appear on a (rumored) future Xbox , we’ll leave for you to decide.

Eerily reminiscent of the design of Sonny and the other NS-5s in I, Robot , Kenshiro is the University of Tokyo’s latest attempt to create a humanoid robot that accurately mimics human movement. And the researchers there believe the best way to build an artificial human is to simply copy our anatomy, particularly our muscular and skeletal systems. More »

Have you ever been playing around with molten metal salt, when you accidentally created hollow, soft-shelled particles that could one day increase hard disk storage or power future QLED displays ? Us neither, but that’s exactly what happened to scientists at Rice University when they were researching “tetrapods” to make solar panels more efficient. Through an apparently wacky coincidence, they removed a single ingredient from the tetrapod stew, which left behind tiny droplets of cadmium nitrate. Selenium then melted around those drops, which completely dissolved away, leaving a melted selenium ball with a hole in the middle. It turns out that those selenium “doughnuts” can be packed tightly onto a metal surface without touching, thanks to their soft shells, which could allow more bits to be packed onto a hard drive, or be used in quantum computers and next-gen displays. Since the dots are smaller than a living cell, it took the researchers an entire year to figure out what they’d made and how they did it — luckily they didn’t just bin the whole thing and start over.

Most video walls would be just a tad too large for the average living room, but the Tokyo University of Technology might have a clever technique to make them travel-sized. Its new Pinch interface joins mobile devices (currently iOS hardware) into a single display simply by making the namesake gesture between at least two gadgets: WiFi keeps them in sync and recognizes the relative size and orientation. While we probably wouldn’t resort to a wall of iPads in place of a large TV , there’s clear practical uses like extra-large creative apps, communication and very local multiplayer games. The best news may be that the university isn’t keeping the technology to itself. It wants developers to borrow Pinch for their own apps, which could lead to a legion of smartphones and tablets getting extra-cozy.

MrSeb writes “A team of researchers from MIT, Caltech, Harvard, and other universities in Europe, have devised a way of boosting the performance of wireless networks by up to 10 times — without increasing transmission power, adding more base stations, or using more wireless spectrum. The researchers’ creation, coded TCP, is a novel way of transmitting data so that lost packets don’t result in higher latency or re-sent data. With coded TCP, blocks of packets are clumped together and then transformed into algebraic equations (PDF) that describe the packets. If part of the message is lost, the receiver can solve the equation to derive the missing data. The process of solving the equations is simple and linear, meaning it doesn’t require much processing on behalf of the router/smartphone/laptop. In testing, the coded TCP resulted in some dramatic improvements. MIT found that campus WiFi (2% packet loss) jumped from 1Mbps to 16Mbps. On a fast-moving train (5% packet loss), the connection speed jumped from 0.5Mbps to 13.5Mbps. Moving forward, coded TCP is expected to have huge repercussions on the performance of LTE and WiFi networks — and the technology has already been commercially licensed to several hardware makers.” Read more of this story at Slashdot.

Several readers have sent word of a significant Amazon EBS outage. Quoting: “Amazon Web Services has confirmed that its Elastic Block Storage (EBS) service is experiencing degraded service, leading sites across the Internet to experience downtime, including Reddit, Imgur and many others. AWS confirmed on its status page at 2:11 p.m. ET that it is experiencing ‘degraded performance for a small number of EBS volumes.’ It says the issue is restricted to a single Availability Zone within the US-East-1 Region, which is in Northern Virginia. AWS later reported that its Relational Database Service (Amazon RDS) and its Elastic Beanstalk application plaform also experienced failures on Monday afternoon.” Read more of this story at Slashdot.
