Crop spray gives plants GMO benefits without altering genes
Scientists have developed a clay-based RNA spray that turns off certain genes in plants, making them resistant to a virus for up to 20 days. With a single treatment, the researchers were able to protect tobacco plants from the "pepper mild mottle virus," a serious disease transmitted by humans during farm operations. On top of crop protection, the technique could be used to modify the color, taste and appearance of plants, but unlike with GMO plants, the underlying DNA would not be changed.
World's longest lab experiment still going strong, via webcam
In 1927, a physics professor named Thomas Parnell launched an experiment on viscous liquids. 85 years later, we're still waiting for his results. It all began with a funnel, a beaker, and some melted tar pitch. Parnell, a professor at the University of Queensland in Australia, was hoping to demonstrate that brittle tar pitch actually behaves as a liquid when kept at room temperature. To prove this, he melted some tar pitch, let it cool for three years, and placed it within the funnel, held over the beaker. The first drop rolled down the funnel eight years later. The second came nine years after that. By the time the third rolled around, Parnell had already passed away. Following his death, the experiment was shelved, quite literally, in a closet, before Professor John Mainstone revived it shortly after joining the University of Queensland in 1961. In 1975, Mainstone successfully lobbied the university to put the experiment on display, but he likely could've never imagined how large an audience it would ultimately have. Today, in fact, the experiment is on display 24 hours a day, via a dedicated webcam. It's been hailed as the world's longest running lab experiment, and it's available for gazing at the source link below. Mainstone expects the next drop to come down the pipeline sometime next year, but you probably shouldn't hold your breath. The last drop ran down the funnel in 2000. Unfortunately, it was never recorded on video, due to a very untimely camera malfunction.
Life-size Angry Birds comes with giant slingshot, more realistic explosive death (video)
Angry Birds was designed to be played on a device that fits in your pocket, so playing the game projected on a wall doesn't exactly feel natural. Throw a life-size slingshot into the mix, though, and things really get zany. The slingshot was on hand at the University of Queensland (Australia) last night, and had apparently been "months in the making." Details are scant, so we're not sure exactly how the slingshot communicates with the game, but however it works, it appears able to do its thing fairly well -- with only a brief delay after release. This slingshot appearance may be a one-time deal, so if you want to try flicking the bird on the big screen, Angry Birds for Chrome (and a mouse) may be your best option for now.
Lingodroid robots develop their own language, quietly begin plotting against mankind
It's one thing for a robot to learn English, Japanese, or any other language that we humans have already mastered. It's quite another for a pair of bots to develop their own, entirely new lexicon, as these two apparently have. Created by Ruth Schulz and her team of researchers at the University of Queensland and Queensland University of Technology, each of these so-called Lingodroids constructed their special language after navigating their way through a labyrinthine space. As they wove around the maze, the Lingobots created spatial maps of their surroundings, with the help of on-board cameras, laser range finders and sonar equipment that helped them avoid walls. They also created words for each mapped location, using a database of syllables. With the mapping complete, the robots would reconvene and communicate their findings to each other, using mounted microphones and speakers. One bot, for example, would spit out a word it had created for the center of the maze ("jaya"), sending both of them off on a "race" to find that spot. If they ended up meeting at the center of the room, they would agree to call it "jaya." From there, they could tell each other about the area they'd just come from, thereby spawning new words for direction and distance, as well. Schulz is now looking to teach her bots how to express more complex ideas, though her work is likely to hit a roadblock once these two develop a phrase for "armed revolt."
Researchers create light-based quantum circuit that does math
It looks like quantum computing could now be one step closer to some form of practicality, as a team of researchers from the University of Queensland have announced that they've created a light-based quantum circuit that's capable of performing basic calculations. According to ZDNET Australia, that was done by using a laser to send "entangled" photons through a linear optical circuit, which allowed them to create a circuit consisting of four "qubits," (or quantum bits, pictured at right), which in turn allowed them to calculate the prime roots of fifteen, three and five. Somewhat interestingly, the university's research is funded in part by none other than DARPA, which the researchers themselves admit may be due to the technology's potential for cracking otherwise uncrackable codes.
