Largest-ever cosmological simulation to shed new light on dark matter
The Bolshoi cosmological simulation is by far the most ambitious project of its kind. It harnesses the power of supercomputing to bring cosmology into the realm of experimental sciences. Based on observable input data, the Bolshoi simulation allows scientists to see what the higher structure of our universe might have looked like at particular points in time throughout its formation, arming them with tools that should make cracking the mysteries of dark matter, dark energy and galaxy formation much more feasible.

Scientists reconstruct visual stimuli by reading brain activity
In the 1983 film Brainstorm, Christopher Walken played a scientist who was able to record movies of people's mental experiences, then play them back into the minds of other people. Pretty far-fetched, right? Well, maybe not. Utilizing functional Magnetic Resonance Imaging (fMRI) and computer models, researchers at the University of California, Berkeley, have been able to visually reconstruct the brain activity of human subjects watching movie trailers - in other words, they could see what the people's brains were seeing.

Some people who spent their youth in the 80s miss that era, and wish that things now were like they were then. Well, those people might be interested in the University of California at Irvine’s OutRun Project. With the ultimate aim of developing gaming therapy systems for people such as quadriplegics, scientists involved in the project have created a kind of combination electric golf cart and arcade-style video game console. Players can actually drive the cart down the road, while an augmented reality feature displays the real-life road on the screen in front of them, but in the form of Sega’s classic 8-bit road racing game, OutRun.

No, it's not just you. According to studies recently conducted by the University of California, Berkeley, the viewing of stereoscopic 3D displays does indeed cause visual discomfort, fatigue and headaches. The problem appears to come from the fact that the viewers' eyes are simultaneously trying to focus on the screen, and on objects that appear to be located either in front of or behind that screen.

People seem to enjoy watching robots and cartoon characters move about, and usually don't mind seeing other humans going through their daily motions, but when it comes to artificial creations that are made to look very human ... they're not always so popular. Although we tend to like animated objects or images that look kind of like real people, once they reach a certain level of realism, they just become spooky. This threshold is known as the "uncanny valley," and an international team of researchers recently set out to determine just what it is about our brains that causes it to occur. Read More
Although ultraviolet semiconductor diode lasers are widely used in data processing, information storage and biology, their applications have been limited by the lasers’ size, cost and power. Now researchers at the University of California, Riverside Bourns College of Engineering have overcome these problems by developing a new semiconductor nanowire laser technology that could be used to provide denser optical disc storage, superfast data processing and transmission and even to change the function of a living cell.

To minimize the toxic effects of chemotherapy, many researchers have been working to develop nanoparticles that that deliver drugs directly to tumors. But researchers at MIT claim that even the best of these nanoparticles are typically only able to deliver about one percent of the drug to their intended target. Now, a team has developed a new delivery system that sees a first wave of nanoparticles homing in on a tumor that then calls in a larger second wave that dispenses the cancer drug. In a mouse study, the new approach was found to boost drug delivery to tumors by over 40-fold. Read More
Practical 'Smell-o-Vision' system being developed
So far as television goes, we're pretty spoilt these days. We can now watch in 3D if we want to, on a screen that is far too big for the once traditional corner-of-the-room placement, and we can also listen to heart-stopping surround sound audio - but there's still more sensory enjoyment to come. Researchers have now managed to create a proof of concept Smell-o-Vision device potentially capable of pumping out thousands of different odors, yet small enough to fit behind a TV. Read More
The results of three recent studies have found that children exposed to organophosphates (OPs) in the womb have a lower IQ at seven years than those that have not. Indoor use of two OPs (chlorpyrifos and diazinon) known to be neurotoxicants have been phased out over the past decade because of health risks, however they are still approved for use in agricultural pesticides and are widely used on food crops. Increasingly scientists are finding that prenatal exposure to pesticides may lead to later health impacts. Read More
Building a robot, it’s probably safe to assume, is a daunting project. It would doubtless be considerably easier if designers didn’t have to build everything from scratch, but could instead use pre-built modules. That’s where the iMobot comes into play. Designed by University of California, Davis alumnus Graham Ryland and professor of mechanical and aerospace engineering Harry Cheng, the modular iMobot is a small robot in its own right, but could also be used as part of a larger robotic system.
