Scientists have had success in tracking the passage of blood cells within the body, by lab...

Thanks to advances in stem cell therapy, it is now possible to use engineered white blood cells to fight diseases such as HIV within the human body. When such treatments are being developed, however, it can be difficult to track where the introduced cells travel within a patient’s system, and how many of them make it to their target. Now, thanks to research being carried out at the University of Edinburgh's Centre for Cardiovascular Science, those cells can be magnetically labeled.  Read More

While they were each once hailed as the lightest solid material ever made, metallic microlattice and aerogel have now been moved back to second and third place (respectively), with aerographite taking the crown. Developed by a team from the Technical University of Hamburg and Germany’s University of Kiel, the material is composed of 99.99 percent air, along with a three-dimensional network of porous carbon nanotubes that were grown into each other.  Read More

MIT doctoral student Saurav Bandyopadhyay has designed a new chip capable of harvesting en...

The problem with depending on one source of power in the drive toward the battery-free operation of small biomedical devices, remote sensors and out-of-the-way gauges is that if the source is intermittent, not strong enough or runs out altogether, the device can stop working. A small MIT research team has developed a low-power chip design capable of simultaneously drawing power from photovoltaic, thermoelectric, and piezoelectric energy sources. The design also features novel dual-path architecture that allows it to run from either onboard energy storage or direct from its multiple power sources.  Read More

Harvard researchers have developed a solid-oxide fuel cell that doubles as a battery

Materials scientists at Harvard have created a fuel cell that not only produces energy but also stores it, opening up new possibilities in hydrogen fuel cell technologies. The solid-oxide fuel cell (SOFC) converts hydrogen into electricity, and could have an impact on small-scale portable energy applications.  Read More

A dish-shaped mirror focuses sunlight onto a glass ball, which distributes it evenly onto ...

Borrowing technology from sophisticated telescope mirrors as well as high-efficiency solar cells used for space exploration, a group of students and researchers at the University of Arizona are putting the final touches on a novel power plant that promises to generate renewable energy twice as efficiently as standard solar panel technology with highly competitive costs and a very small environmental impact.  Read More

An Israeli zoologist plans on studying bat behavior by equipping captive-raised bats with ...

Given that most bats hang out (literally) in caves and other secretive places, and only fly at night, they’re not the easiest of creatures to study. Tel Aviv University zoologist Dr. Yossi Yovel, however, has a plan. He is currently establishing the world’s first bat colony to be born and raised in captivity. Although the resulting “roost” will be based out of a research facility, the bats will be free to come and go to hunt for insects in the surrounding environment. As they do so, some of them will be equipped with high-tech sensors designed to gather information on their behavior.  Read More

One of the more promising developments in the field of medical technology involves the use of microspheres for targeted drug delivery. In a nutshell, this encompasses creating tiny hollow balls that are filled with a specific drug, which travel directly to a specific organ or area of diseased tissue. Once there, the spheres release their medication, keeping it concentrated where it’s needed while sparing other tissue from any harmful side effects. Recently, a team of scientists from Germany’s Max Planck Institute of Colloids and Interfaces devised a new method of manufacturing such microspheres, which is said to offer several advantages over existing techniques.  Read More

The pyramid patterns created in a polymer sheet increase current production in the new tri...

Researchers at the Georgia Institute of Technology have taken advantage of the triboelectric effect, which sees an electric charge generated through friction between two different materials, to develop a generator that could supplement power produced by piezoelectric nanogenerators previously developed at Georgia Tech. The triboelectric generator could be used to produce electricity from activities such as walking and even has the potential to create touchscreens that generate their own power.  Read More

A team of researchers at Griffith University has managed to stretch the capabilities of microscopy to its ultimate limit. Culminating a five-years effort, the scientists have obtained a digital image of the shadow cast by a single atom, in a development that might soon lead to important advances in scientific observations ranging from the very big to the very small.  Read More

New technology based on the eye of a moth improves the quality of X-ray images without com...

To increase stealth and evade predators, the moth has evolved a remarkable eye that, rather than reflecting light, absorbs it almost completely. Engineers have mimicked its nanostructure in the past to design better solar panel coatings and antireflective surfaces, and are now using the same principle to design a thin film that will absorb radiation from X-ray machines more effectively, exposing patients to a significantly lower risk while obtaining higher quality imaging.  Read More
