Recent demonstration of quantum levitation during the 2011 Association of Science- Technol...

Maglev trains have been in development since before Luke Skywalker drove his first Land Speeder but, like personal rocket packs, the idea of levitating transport is taking a while to catch on. While this "quantum levitation" demonstration shown by the superconductivity group at Tel Aviv University at the 2011 ASTC annual conference in Baltimore doesn't mean we'll all be floating to work anytime soon, it does remind us of the amazing potential of this kind of technology.  Read More

The design of an 'AND gate' created by Imperial College London scientists using E-Coli bac...

DNA is often referred to as the building block of life. Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a computer - logic gates. Using DNA and harmless gut bacteria, the scientists have built what they claim are the most advanced biological logic gates ever created by scientists. The research could lead to the development of a new generation of microscopic biological computing devices that, amongst other things, could travel around the body cleaning arteries and destroying cancers.  Read More

By applying electrical pulses to the new nanomaterial, a sea of small negatively charged i...

By now, we’re all fairly used to electronic devices such as smartphones, which can act as a mobile phone, computer, camera and navigation unit all at once. These devices, while multi-functional, still use different hard-wired electrical circuits for their different functions. Thanks to research being carried out at Chicago’s Northwestern University, however, all those functions may one day be able to utilize the same physical piece of electronic material – the electrical current would simply be “steered” through it differently, depending on what was needed. This means that a single section of the material could act as a resistor, rectifier, diode or transistor, as instructed by a computer.  Read More

Each nanochannel electroporation device incorporates two reservoirs joined by a nanoscale ...

One of the key processes in gene therapy involves taking cells from the patient, injecting a therapeutic genetic material into them, then reintroducing them to the patient’s body and letting them go to work. Unfortunately, getting that material into the cells can be tricky. While larger cells can actually be punctured with a fine needle, most human cells are too small for that approach to be possible. There are also methods of inserting random amounts of material into bulk quantities of cells, but these are inexact. Now, however, scientists at Ohio State University are reporting success with a process known as “nanochannel electroporation” (NEP), in which therapeutic biomolecules are electrically shot into cells.  Read More

Amateur astronomers wanting to observe celestial bodies soon won’t be limited to just their own personal telescopes, or visits to the local public observatory. Starting next year, the first in a worldwide network of robotic telescopes will be going online, which users from any location on the planet will be able to operate for free via the internet. Known as Gloria (GLObal Robotic telescopes Intelligent Array for e-Science), the three-year European project will ultimately include 17 telescopes on four continents, run by 13 partner groups from Russia, Chile, Ireland, the United Kingdom, Italy, the Czech Republic, Poland and Spain. Not only will users be able to control the telescopes from their computers, but they will also have access to the astronomical databases of Gloria and other organizations.  Read More

A microformulator, designed to allow ABE to perform experiments without human intervention...

While some people may have been impressed (or intimidated) by the recent development of a system that automatically raises and analyzes cell cultures, it turns out that another facet of the biological research process may also be going to the machines. An interdisciplinary team of researchers recently demonstrated a computer system that is able to take in raw scientific data from a biological system, and output mathematical equations describing how that system operates - it is reportedly one of the most complex scientific modeling problems that a computer has solved entirely from scratch. While the system is known affectionately as "ABE," it is also being referred to as a robotic biologist.  Read More

Scientists have created a tiny artificial muscle, that could be used in motors to propel n...

We've been hearing a lot lately about the possibility of treating medical conditions using nanobots - tiny robots that would be injected into a patient's bloodstream, where they would proceed to travel to their targets, not unlike the microscopic submarine in the movie Fantastic Voyage ... except nanobots wouldn't be crewed by tiny shrunken-down humans. One challenge that still needs to be met, however, is figuring out a way of propelling the devices. Well, we may now be closer to a solution. Yesterday, development of a new type of nanoscale artificial muscle was announced, which works like the muscles in an elephant's trunk. These could conceivably be used in nanobots, to whip them along using a rotating flagellum - a tiny sperm-like tail, in other words.  Read More

New computer modeling technology suggests that Tyrannosaurus rex was even larger than prev...

Tyrannosaurus rex, that coolest of all the dinosaurs, may have been even bigger and scarier than originally thought. That’s the conclusion that was recently reached by a team of scientists, who used computer modeling technology to estimate the average body mass of the carnivorous dinosaurs. After digitally “fleshing out” existing T. rex skeletons, the researchers now believe that the reptiles grew twice as fast, and reached adult weights up to 30 percent higher than previously assumed.  Read More

Cornell researchers have demonstrated a working temporal cloak that creates a gap in the f...

Last year researchers at Imperial College London proposed that along with being used to cloak physical objects metamaterials could also be used to cloak a singular event in time. A year later, researchers from Cornell University have demonstrated a working "temporal cloak" that is able to conceal a burst of light as if it had never occurred.  Read More

The 'Questionable Observer Detector' is a computer system that is able to identify people ...

Chances are, you’ve seen at least one or two TV shows in which the police examine news footage shot at several different crime scenes, and recognize the same person’s face showing up repeatedly in the crowds of onlookers ... the ol’ “criminal returning to the scenes of their crimes” scenario. Realistically, it’s pretty hard to believe that one person could look through all that footage, and remember all those faces. It turns out that a computer could do it, however, as scientists at Indiana’s University of Notre Dame have illustrated with their “Questionable Observer Detector," or QuOD.  Read More
