With the release of Baby Plumen 001, a shrunken version of its award-winning Plumen light bulb, Hulger is making a clear statement that the humble fluorescent light bulb isn't ready for the trash just yet.  Read More

There are several techniques used by researchers and physicians to image the internal organs of people and animals, but each of these techniques have their shortcomings. X-rays and computed tomography (CT) scanning, for instance, involve exposing the subject to radiation. Magnetic resonance imaging (MRI) is safer, although subjects must sometimes ingest a contrasting agent in order to obtain more distinct images. The use of injected colored fluorescent proteins is another approach, but has been limited by the fact that hemoglobin in the subject’s blood absorbs much of the wavelength of the light used for imaging. Now, however, scientists from New York’s Albert Einstein College of Medicine of Yeshiva University have engineered a new fluorescent protein that sidesteps this limitation.  Read More

Statistics indicate that complete removal, or resection, of a tumor is the single most important predictor of patient survival for those with solid tumors. So, unsurprisingly, the first thing most patients want to know after surgery is whether the surgeon got everything. A new hand-held device called the SpectroPen could help surgeons provide a more definite and desirable answer by allowing them to see the edges of tumors in human patients in real time during surgery.  Read More

Although great strides have been made recently to make offices more energy efficient, fluorescent office lighting is still great cause for concern. Installing controllers which automatically switch off lighting when no movement is detected is one method of saving energy but Solaroad Technologies proposes recycling otherwise wasted light energy by placing cylindrical photovoltaic harvesting and storage devices on top of workstation cubicle walls.  Read More

If you’re trying to reduce your carbon footprint, replacing traditional fluorescent tube lighting with more energy-efficient alternatives is a good way to start. And when most of us think fluorescents, we think ceiling lights. The fact is, though, a great deal of the world’s fluorescent lights are installed somewhere else - in grocery store coolers and freezers. The creators of a new product called Posilight are hoping to replace those tubes with their own LED-based product that will save power, save money, and save food.  Read More

Up until now, for a projector to pack a decent punch it has had to incorporate a high pressure lamp using mercury, which as we all know is a dirty word environmentally. Casio has this week at CES announced the Green Slim range of mercury-free super slim high powered projectors that use a combination of LED, laser and fluorescent illumination capable of brightness up to 3000 lumens, as well as featuring wireless and USB capability.  Read More

Nanotechnology is preoccupying science to the point where it's starting to seem unremarkable. But a group of researchers from the University of Washington has released findings that could profoundly improve the chances of surviving brain cancer. The team has developed a fluorescent nanoparticle that is capable of penetrating – for the first time – the blood-brain barrier without damaging it. The fluoro nanoparticle targets tumors using a derivative of scorpion venom and enables precise imaging of the size and location of cancerous growths. When the particles meet the tumor, they light up like Christmas.  Read More
