VirtualDose utilizes computer models of different body types to advise physicians on which...

X-ray computed tomography – or CT – scanners are designed with people of an average build in mind. When obese patients require a CT scan, the additional layers of body fat will produce blurry images if the scanner’s regular settings are used. Clinicians typically address this problem by turning up the power of the scanner. Unfortunately, doing so results in overweight patients receiving higher-than-normal doses of radiation. A new computer modeling system developed at New York’s Rensselaer Polytechnic Institute, however, could help bring those levels down.  Read More

Fans of the classic 1982 science fiction movie Blade Runner will remember the ESPER machine that allows Deckard to zoom in and see around corners in a two-dimensional photograph. While such technology is still some way off, researchers in MIT’s Media Lab have developed a system using a femtosecond laser that can reproduce low-resolution 3D images of objects that lie outside a camera’s line of sight.  Read More

Researchers at the University of Sheffield have created what sounds impossible - even nonsensical: an experimental electron microscope without lenses that not only works, but is orders of magnitude more powerful than current models. By means of a new form of mathematical analysis, scientists can take the meaningless patterns of dots and circles created by the lens-less microscope and create images that are of high resolution and contrast and, potentially, up to 100 times greater magnification.  Read More

With a superlens microscope, everyday people would be able to see minute details of tiny o...

Some day, you may have a microscope on your smartphone camera that's as powerful as a scanning electron microscope. If you do, it will likely be thanks to research presently being conducted by Durdu Guney, an assistant professor of electrical and computer engineering at Michigan Technological University. He is working on creating a metamaterial-based "superlens" - a long sought-after optically-perfect lens, that could use visible light to image objects as small as 100 nanometers across.  Read More

From nude pictures of celebrities to politicians caught in compromising positions, verifying the authenticity of images online is often no easy task. To address this problem, a team at Duke University looking has developed software called YouProve that can be integrated into the Android operating system to track changes made to images or audio captured on an Android smartphone. The software then produces a non-forgeable "fidelity certificate" that uses a "heat-map" to summarize the degree to which various regions of the media have been modified compared to the original image.  Read More

BAE Systems has been selected by Lockheed Martin to supply a Night Vision Goggle Helmet Mo...

When it enters service, the F-35 Lightning II Joint Strike Fighter will lay claim to the title of the most advanced warplane in the world. Its pilots will have the most advanced helmets as well ... and there's more to it than protecting the pilot's head against knocks. Unfortunately, the gap between designing the helmet and building it has proven wider than originally thought and issues such as poor image quality are so severe that the F35's testing program faces serious delays, so F-35 prime contractor Lockheed Martin brought in BAE Systems to provide a substitute.  Read More

A team from the University of California at Davis has developed an affordable way to give the iPhone surprisingly capable chemical detection and imaging powers. We've reported on cellphone microscopes before, but this version claims to be simpler in concept and less expensive, plus it adds spectroscopy to its list of abilities  Read More

When it comes to laboratory equipment, it doesn’t get much more basic than the humble petri dish. Aside from moving from glass to plastic and the addition of rings on their lids and bases that allows them to be stacked, the petri dish has remained largely unchanged since its invention by German bacteriologist Julius Richard Petri and his assistant Robert Koch in the late 1800s. Now researchers at the California Institute of technology (Caltech) have dragged the petri dish into the 21st Century by incorporating an image sensor like those found in mobile phone cameras that does away with the need for bulky microscopes.  Read More

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.  Read More

The clear mouse embryo on the right was incubated in the Scale reagent for two weeks

Scientists are constantly looking for new and better ways of seeing through biological tissue, in order to see cells within it that have been marked with dyes, proteins or other substances. While recent research has involved using marking materials such as carbon nanotubes and firefly protein, scientists from Japan’s RIKEN Brain Science Institute have taken a different approach – they’ve developed a chemical reagent that causes the tissue surrounding the marked cells to become transparent.  Read More
