In order to maintain a consistent buoyancy as their cargo loads change, ocean-going ships pump seawater in and out of their ballast tanks. Needless to say, that salty water isn't exactly the least-corrosive liquid in the world. That's why crews of inspectors regularly have to go inside those steel tanks, to check for damage. Thanks to the German/Dutch RoboShip project, however, autonomous robots may soon be performing the task. Read More
Given that there isn't any gravity on the International Space Station you’d think that shoes would be a very low priority, but on the latest Russian Soyuz capsule to dock with the station, NASA sent along a pair of high-tech ForceShoes to monitor astronauts as they exercise to make sure they get the full benefits of their workouts.

When it comes to moving simply but effectively through a liquid medium, few things are as good as sperm. This fact isn't lost on scientists, who have built tiny sperm-like robots (or even used "hijacked" sperm) in efforts to create new methods of targeted drug delivery, among other potential applications. The latest such endeavor has resulted in a batch of microrobots known as MagnetoSperm. Read More
If you’re going to do something like building a Porsche 911 that fits on the head of a pin, or make a microscopic medical pump, you need a microscopic engine. A team of researchers from the University of Twente in the Netherlands, the Russian Academy of Sciences, and Germany’s University of Freiburg have developed a micro-engine that burns oxygen and hydrogen, but there’s a small problem; they’re not sure how the thing works.

A researcher at the University of Twente in the Netherlands has developed a new optical memory disc out of tungsten and silicon nitride that he says could store data safely for extremely long periods of time – up to a billion years. Read More
While breast cancer screening tests are accepted as safe – and we definitely wouldn’t want to scare anyone off from a potentially life-saving test – they do have some risks associated with them. The most obvious being the exposure to low doses of ionizing radiation, which in itself is a risk factor for breast cancer. X-ray mammography can also give false positive and negative results. In the quest for a safer, more accurate alternative, Dutch researchers have provided proof of concept that photoacoustic imaging can be used to detect and visualize breast tumors. Read More
While just about everyone is familiar with home pregnancy testing kits, what many of us may not realize is that a (sort of) equivalent product exists for men - home sperm count kits. These kits, however, will simply tell users if their sperm count is above or below a standard value. While a yes or no answer like that might suffice for the pregnancy kits, a little more information would definitely help a man who suspects he might be infertile. Loes Segerink, a PhD student from The Netherlands' University of Twente, hopes to change that with this prototype lab-on-a-chip device. Segerink's chip counts exactly how many sperm are present in a sample of ejaculate, and can even differentiate between the good swimmers and the duds. Read More
There may not be many people interested in the precise measurement of all the forces and movements that are at play as someone walks, but for those few, a new tool has been developed to help them carry out their research - ForceShoes. Developed by researchers at the University of Twente's MIRA research institute in The Netherlands, these modest-looking sandals feature high-tech data-gathering electronics. Read More
As chips continue to get smaller, the technological possibilities just get larger. One of the trade-offs of miniaturization, however, is that smaller things are also often more fragile and less dependable. Anticipating a point at which chips will become too tiny to maintain their current level of resilience, a team of four companies and two universities in The Netherlands, Germany, and Finland have created what they say could be the solution – a chip that monitors its own performance, and redirects tasks as needed.

In a new, more efficient approach to solar powered microelectronics, researchers have produced a microchip which directly integrates photovoltaic cells. While harnessing sunlight to power microelectronics isn't new, conventional set-ups use a separate solar cell and battery. What sets this device apart from is that high-efficiency solar cells are placed straight onto the electronics, producing self-sufficient, low-power devices which are highly suitable for industrial serial production and can even operate indoors.
