Remember when, as a kid, you would pass “top-secret” notes written in lemon juice that your friends could only read in the right light? Well, in light of new nanotechnology research, this now sounds absurdly antiquated, like cave painting in the modern era. Instead, the youth of tomorrow (and adults too) could have the option to communicate via documents that self-erase at a preprogrammed time.
In the movies, entrusting human life to robot helpers and sophisticated machines inevitable ends in fire, destruction and death. But in reality, the automatons are actually saving lives. We featured six Machines that Heal in our July issue, one of which is Twendy-One, a Japanese robot nurse straight out of the comic books built to assists the elderly.
I was always told that learning a skill like juggling or playing an instrument requires three things: practice, practice and practice. Now, researchers have found a way to shorten the path to new motor skills to practice, practice and magnetic brain stimulation.
As one of his first acts as president, Barack Obama dismissed former-president Bush's rules governing the federal funding of stem cell research. And on Monday, the National Institute of Health issued its new set of replacement guidelines.
The new rules overturn the ban on creating new cell lines, establish a registry of stem cell lines approved for federally funded research, and create a system where stem cell lines approved under previous guidelines can petition for federal funding under the new regime.
There's something magnificently creepy about this tiny bot, just one millimeter wide, developed at Israel's Technion University. Maybe it's the resemblance to a twitching tick or flea, or the fact that it's so small there could be insectile bots all around you right now and you'd hardly notice. (The robot, called Virob, has no internal power source--it derives its power from external magnetic fields.
Or maybe it's that the bug is designed to infiltrate human veins, autonomously crawling around our circulatory systems, taking pictures and poking its feelers where no 'bot has gone before.
Researchers from Tel Aviv University believe they've found a way to detect the severity of an oncoming flood in any given location using date from the area's network of cell towers. But it doesn't make use of human to human communications; instead, it revolves around measuring humidity in the air.
Despite it being in many ways a marvel of modern technology, the International Space Station can't keep up with even the simplest modern cellphone in terms of data communication with Earth. Disruption-Tolerant Networking, a new protocol for transmitting data in space being developed jointly by NASA, Google's "Chief Internet Evangelist" and others, hopes to change that.
Ever wondered what your brain sounds like on the inside? Trinity College philosophy professor Dan Lloyd has created a program that orchestrates our brainwaves. Scanning brains on an MRI, Lloyd can watch as certain areas of the brain light up and then assign different frequencies to the areas of the brain used, correlating the intensity of usage with volume. The results are bizarrely beautiful.
