Solutions that reduce death of marine life reeled in by International Smart Gear Competition

...hted, deep-set gear. An innovative combination of glowing ropes and stiffer nets--the results of collaboration among a chemist, biologist and fisherman--was recognized as a runner up with $5,000 in the "cetaceans" category. More than 300,000 whales, dolphins and porpoises--or cetaceans--are estimated to die...

Firefly protein lets researchers monitor molecule linked to cancer

Scientists have used a glowing protein from fireflies to observe the activity of a molecule that is an important target for new drugs to treat cancer, autoimmune diseases and several other disorders. The target molecule, known as IKK (for IKappa kinase), regulates processes that ...

By providing a way to quickly sex mosquitoes, the advance paves the way for pooling large numbers of sterile males which could be used to control the mo...

Scientists seek to unwrap the sweet mystery of the sugar coat on bacteria

... Mahal and her colleagues can read the patterns of glowing dots and determine which sugars coat the bacteria. The microarray technique worked fast enough that the researchers were able to see the sugar coating change over time in the neonatal meningitis strain of E. coli. "Over time, the lectins lost their...

Mice with glowing hearts shed light on how hearts develop

...rs have also transplanted cells from the mice with glowing hearts into normal mice to see whether the transplanted cells function normally within the host heart, which could offer insights for heart repair. In the study, the mouse was engineered to express a specially designed molecule that fluoresces when ...
