Fluorescent

The Cree T8 is an LED tube designed to replace conventional fluorescent tubes

Fluorescent lights aren't on the top of many people’s favorites list. Ever since they were introduced at the New York World’s Fair in 1939, they've been notorious for their cold, bluish light that is the definition of “uncomplimentary” and accompanied by flickering and a telltale buzz. Cree, Inc. is aiming to relegate fluorescent tubes to the pages of history with its new T8 series of LED tubes that promise LED-level energy savings and greatly improved light quality.  Read More

In testing the fluorescent compound, the team observed a difference in the intensity of th...

Central to the dangers of so-called "date-rape" drugs is the fact that they are difficult to detect. Indeed, GHB, one of the most commonly-used of such drugs, is both colorless and odorless. A team of researchers from the National University of Singapore (NUS) has developed a fluorescent sensor which, when mixed with a drink containing GHB, changes color within 30 seconds, potentially alerting people soon after their drink has been tampered with.  Read More

A rendering of the nanometer-scale DNA clamp, that recognizes genetic mutations more stron...

Scientists have developed a special DNA clamp to act as a diagnostic nano machine. It's capable of detecting genetic mutations responsible for causing cancers, hemophilia, sickle cell anemia and other diseases, more efficiently than existing techniques. Not only can the clamp be used to develop more advanced screening tests, but it could also help create more efficient DNA-based nano machines for targeted drug delivery.  Read More

Helicobacter Pylori bacteria, fluorescing green

Research carried out by a team of scientists at the University of Southern Denmark literally sheds new light on how a non-invasive technique for the early diagnosis of stomach ulcers could be performed in the future. The findings of the researchers point to a fast, hassle-free method that does not require sample tissues, unlike current testing methods.  Read More

Scientists have created piglets that glow green under a black-light (see the video below)

Scientists in Guangdong Province, Southern China, have created piglets that glow green under a black-light. The glow is caused by a fluorescent protein from jellyfish DNA that was transferred into the embryos within the sow, as a marker to show that the transfer of genetic material had been successful.  Read More

A Lumicyano-treated fingerprint on a plastic bag

If you regularly watch any police forensics TV shows, then the word "Luminol" is probably already part of your vocabulary. Now, however, you might also want to add the word "Lumicyano." That's the name of a new product that is said to reveal latent fingerprints faster, cheaper and better than other methods.  Read More

A glowing Japanese freshwater eel – it's more than just tasty

Just about any sushi-lover knows what unagi is – it’s eel, or more specifically, the Japanese freshwater eel Anguilla japonica. What those people might not know, however, is that the eel glows green in the dark. Now, it looks like the protein that allows the fish to do so could also help doctors to assess human liver function.  Read More

Fluorescent lights are one of those things that you see everywhere, but that nobody likes. They flicker, they hum, they produce a rather unattractive light, plus they’re fragile and contain toxic substances. They may also be on their way out – scientists from North Carolina’s Wake Forest University have created a new form of lighting that they say could be used in the same large-scale applications as fluorescent bulbs, but that lacks their shortcomings.  Read More

The Baby Plumen is better suited to regular lightbulb duties than its elder sibling

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

Fluorescent near-infrared waves pass readily through a mouse's tissues to reveal its brigh...

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
