A team of researchers from the University of Melbourne has developed a new way to turn plants into nanomaterial factories, which could allow them to act as chemical sensors or even allow them to survive in harsh environments, such as in space or on Mars.

The earlier cancer is detected, the better the odds of treating it, but tumors can be hard to spot until they get to a certain size, at which point it might be too late. Now MIT researchers have developed a new optical imaging system that could be used to spot tiny tumors deep inside the body.

If scientists can see how bacteria evolves, they might be able to intervene to prevent drug resistance. Now researchers at Indiana University have produced the first direct images of bacteria extending “harpoons” to snare and absorb bits of DNA.

Chameleons are well-known for their ability to change colors, but scientists have just discovered a new visual trick in the creature’s repertoire. Under UV light many types of chameleons have been found to fluoresce in vibrant patterns, which they may use to communicate with others of their species.

ScienceResearchers have developed tiny, glowing crystals that can both detect and trap toxic heavy metals at the same time. Similar research has been done on structures to either detect or remove such nasty substances, but this appears to be the first capable of doing both.

A team of University of Glasgow researchers has worked to improve the imaging provided by swallowable cameras used to detect cancers in the throat and gut. The new video pills are able to emit fluorescent light, allowing the researchers to better analyze the returned imagery.

Phosphors are essential to fluorescent lighting, and thus office parks the world over, but their use of rare-earth elements makes them less than ideal. Now new types of phosphors have been developed that use substantially less rare-earth elements than current phosphors found in fluorescent bulbs.

ScienceA cheap 3D-printed attachment can turn smartphones into sophisticated microscopes. Armed with the new device, a smartphone would be able to detect single DNA strands and analyze them to diagnose diseases including cancer and Alzheimer’s without bulky and expensive equipment.

This year's winners of the Nobel Laureates in Chemistry, Eric Betzig, Stefan W. Hell, and William E. Moerner, are honored for their discovery of two methods to bypass the physical limits of optical microscopes to create the field of nanomicroscopy.

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.
-
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.

ScienceScientists 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.
