Scientists trace a cosmic radio burst to its home galaxy
Fast radio bursts in space have confused the astronomy community for years. What causes them, and where do they come from? At last, researchers are getting some answers. For the first time, scientists have traced one of these bursts back to its home galaxy. They first used the Karl G. Jansky Very Large Array radio telescope to pinpoint the object's exact location, and then used the Gemini North telescope to create an image of that patch of sky. The most surprising part isn't how they did it, though -- it's where the radio blasts are coming from.
3D-printed titanium hips will last longer with less pain
A mechanical engineering professor at McGill University has designed a new 3D-printed titanium hip replacement that will not only take the place of your aging femur, but can also fool the living bone into working harder for longer. According to the University, Damiano Pasini's femoral stem is printed with a "hollowed-out tetrahedra" design that resembles the porousness of actual bone, rather than dense materials of older hip replacements.
McGill University student plan provides healthcare to rural areas with Windows Phone and Win 8
Those of us living in metropolitan areas don't think twice about our ease of access to medical care, but those in rural areas don't enjoy such easy access to a doctor. Abhijeet Kalyan and Shravan Narayan from McGill University in Canada are aware of this problem, and came up with a way for doctors to diagnose and treat patients from afar. Called Project Neem, it's got a hub and spoke organizational structure that puts a healthcare worker in every village and leverages the power of Windows Phone to connect them with medical staff in distant cities. Participating healthcare workers are given basic medical training and a handheld loaded up with a custom app that identifies patients by scanning their national ID card and stores their pertinent medical info -- from temperature and blood pressure readings to a variety of symptoms. The app has a virtual human body on board that lets users tap parts of the anatomy to bring up a series of symptoms that can be selected to provide treating physicians with the info they need. That information is stored in the cloud and accessed by doctors through a Windows 8 app, who then can relay appropriate treatments to the local healthcare worker. Now all we need is someone to make a real-world tricorder, and we'll truly be able to bring medical care to the masses, wherever they may be.
Intubation bot lets doctors safely shove tubes down unconscious human throats
We've seen all manner of medical robots 'round these parts, from bloodbots to surgical cyborgs. And now Dr. Thomas M. Hemmerling from McGill University Health Centre (who also helped develop the McSleepy anesthetic android) has created the world's first intubation robot. Called the Kepler Intubation System (KIS), it's a robotic arm with a video laryngoscope that's controlled via joystick -- allowing MDs to get their Dr. Mario on while sliding an endotracheal tube into any passed-out meatbag with minimal fuss and maximum safety. The first procedure using the device on a real, live human was a success, and clinical testing continues. We're not big on bots shoving anything anywhere (even if it does help us breathe while under the knife), but that's better than android appendages lobbing grenades our way.
Study shows love for music relates to brain chemical, not to My Chemical Romance
It would make sense that people listen to music for the sheer pleasure of it, right? That's what we thought, but apparently there's a scientific reason for this. Scientists have discovered that when Earthlings listen to pleasurable music, one particular chemical is loosed in the gord. The study, conducted by Robert Zatorre and Valorie Salimpoor of McGill University in Montreal, concluded that when the participants tuned into instrumental pieces they were familiar with, their brains released dopamine into the striatum -- an area of the noggin linked with anticipation and predictions. According to PET scans, the members of the study unleashed the chemical 15 seconds before a climaxical moment in a song, signaling the possibility that humans may actually release it in anticipation and not as a reaction to a wailing solo. Bonus point? Chopped and screwed tracks unleashed forty times more dopamine. Just kidding, but it's probably true.
McGill University researchers show off lunar rover prototype with unique 'iRing' wheels
We've already seen researchers at the University of Chicago and Cornell use coffee grounds to develop an entirely different type of robotic hand, and it looks like some folks at McGill University in Montreal, Canada have also been taking a similar approach to quite literally reinvent the wheel. That's being done as part of the Lunar Exploration Light Rover (or LELR) project, which is aiming to build a lunar rover that's light and able to navigate difficult terrain (i.e. the surface of the moon) with ease. One of the key aspects of that, of course, are the wheels, and the McGill researchers' solution is something called the "iRing" -- a wheel made of a chainmail-type fabric and filled with "granular particulate matter" (or tiny pieces of metal). That creates a wheel that's heavy and sturdy enough to avoid bouncing around on the moon, but still flexible enough to absorb shocks and overcome any obstacles. Will it actually wind up on the moon? That remains to be seen, but the researchers expect the final prototype of the complete rover (which could even carry a crew) to be complete in the spring of 2012. Be sure to hit up the via link below for the best look at the rover on video.
First all-robot surgery performed at McGill University
A team of surgeons at McGill University, including the da Vinci robo-surgeon and a robot anesthesiologist named, of all things, McSleepy, recently removed some dude's prostate during what is being billed as the world's first all-robotic surgery. The device transmits hi-def 3D images to a nearby workstation, where it is controlled by surgeons "with a precision that cannot be provided by humans alone," according to MUHC urologist-in-chief Dr. A. Aprikian. Of course, the robots are being kept on a tight leash by their human operators, with McGill's Dr. Thomas Hemmerling pointing out that "[r]obots will not replace doctors but help them to perform to the highest standards." Just tell that to all the other medical robots we've seen in this space, eh, doc? We've heard they have plans. Bad plans.
AQUA2 amphibious robot is super cute and fast, less annoying than most pets because it has no head
The AQUA2, built at McGill University in Montreal, is the first of its kind. You see, the AQUA2 is a robot that can both dive and swim in water, and move about on land. The amphibious bot can explore water up to 120 feet and is tethered to a remote control via ethernet or fiber optics. The 'headless' robot's flippers make it a pretty impressive swimmer, and it's also strikingly fast on even rough terrain. Check out the video after the break.
3D printer creates ice sculptures -- just add water
Paper-mache, candy, and human cells have all been seen flowing through 3D printers for custom fabrication work, but students and faculty at Canada's McGill University have a cheaper prototyping material: plain ol' H2O. They recently modified this Fab@Home Model 1 by replacing the soft goo extruders with a temperature-controlled water delivery system, and set about making decorative ice sculptures and a large beer mug for good measure. While the academic project is officially supposed to explore "economic alternatives to intricate 3D models of architectural objects," we're not sure architects will want much to do with prototypes that drip... but tourism might well get a boost from liquor sold in frosty custom containers. We're thirsty just looking at them.
Researchers say new state of matter could extend Moore's Law
There's certainly been no shortage of folks trying to pin down an end date for Moore's Law, but there's also thankfully plenty of researchers doing their best to keep it going, and a team of physicists from McGill University in Montreal now say they've made a discovery that could keep the law alive even further into the future. Their big breakthrough is a new state of matter known as a quasi-three-dimensional electron crystal, which they discovered in a semiconductor material by using a device cooled at temperatures "roughly 100 times colder than intergalactic space," and then exposing the material to the "most powerful continuous magnetic fields generated on Earth." Unlike two-dimensional electron crystals, which lead researcher Dr. Guillaume Gervais equates to a ham sandwich, the quasi-three-dimensional electron crystals are in an "in-between state" between 2D and 3D, which could potentially allow for transistors to improve further as they run up against the physical limits imposed by the laws of physics.
