Researchers at the University of Connecticut have made a new material that emits bright white light by adding fluorescent dyes to DNA and then spinning the DNA strands into nanofibers, according to a paper published online in the journal Angewandte Chemie. The researchers create white-light-emitting devices by coating ultraviolet (UV) light-emitting diodes (LEDs) with the material. They are even able to fine-tune the white color tone to make it warm or cold.

Organic light-emitting diodes (OLEDs), fabricated with layers of organic polymers, are flexible and use less power and less expensive materials than liquid crystal displays. However, OLEDs are expensive to produce-- because the polymers react easily with oxygen and water, they have to be created in high-vacuum chambers--and they need extra protective packaging layers to make sure that once they're integrated into display devices, they don't degrade when exposed to air or moisture.

Scientists have developed a method to make lettuce darker and healthier using ultraviolet (UV) light-emitting diodes (LEDs).
Steven Britz of the U.S. Department of Agriculture and his colleagues used low-power LEDs that exposed lettuce to ultraviolet B (UVB) light for 43 hours. The lettuce was noticeably darker than plants not exposed to the UVB. They have not quantified this effect, but the lettuce darkening increased with the intensity of the light.
Darker lettuce, like spinach, is known to be more nutrient dense than its lighter counterparts, such as iceberg.
