Photoacoustic imaging promises breast cancer screening without ionizing radiation
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.

Solar powered microchips put batteries in the shade
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.

New chip could allow antenna arrays to replace satellite dishes
There was a time not so very long ago when people who wanted satellite TV or radio required dishes several feet across. Those have since been replaced by today’s compact dishes, but now it looks like even those might be on the road to obsolescence. A recent PhD graduate from The Netherlands’ University of Twente has designed a microchip that allows for a grid array of almost-flat antennae to receive satellite signals. Read More
It's much, much smaller than its Stradivarian cousin, but not even the Borrowers, Lilliputians or Blefuscudians are of sufficiently diminutive proportions to take a bow to the Micronium. The tiny instrument is made up of microscopic springs activated by combs to produce an audible tone. Half a dozen tone systems are placed on a chip and then chips combined to offer an orchestral range of sounds. Read More
Anyone who's ever had to drum up the courage to visit a male fertility center will agree that today's process for sperm counting is at best awkward, and at worst embarrassing, messy and intimidating. So if you'll pardon the pun, it will come as a relief to many that a "lab on a chip" device is being developed that can let guys do their own sperm counts at home - avoiding the embarrassment and inconvenience, if not the mess. That's gonna be fun at parties. Warning: uncomfortable anecdote after the jump. Read More
In a recent issue of the journal Nature, researchers from the University of Twente, Netherlands, explain how they succeeded in transferring magnetically coded information directly into a semiconductor, for the first time at room temperatures. Meanwhile, Toshiba announced at the International Electronics Devices Meeting (IEDM) it has developed a MOSFET transistor harnessing spintronics, demonstrating stable, fast and low-power performance.

August 9, 2007 Anyone who has used a wireless mouse will know that although they don't use much power, it's enough to drain a battery quite regularly and it always decides to run out of power at the most inopportune times. Now comes news of the world's first exclusively photovoltaic-powered computer mouse currently undergoing trials in the Netherlands. Read More
