New Fluorescent Dyes Could Advance Biological Imaging

HHMI is a science philanthropy whose mission is to advance basic biomedical research and science education for the benefit of humanity. HHMI supports people, rather than projects, because it’s individual scientists who break barriers to advance knowledge. Scientists at HHMI’s Janelia Research Campus have developed a new method for fine-tuning the structure of rhodamine dyes, and can now create a colorful palette of fluorescent molecules. Swapping out specific chemical building blocks in fluorescent molecules called rhodamines can generate nearly any color scientists desire –­ ­ROYGBIV and beyond, researchers report September 4, 2017 in the journal Nature Methods. The work offers scientists a way to adjust the properties of existing dyes deliberately, making them bolder, brighter, and more cell-permeable too. Such an expanded palette of dyes could help researchers better illuminate the inner workings of cells, says study leader Luke Lavis, a group leader at the Howard Hughes Medical Institute’s Janelia Research Campus in Ashburn, Virginia. His team lit up cell nuclei, made larval fruit fly brains shine, and highlighted visual cortex neurons in mice that had tiny glass windows fit...

Commentary: Yellow Ribbon Program offers aid | Opinions

Partly cloudy with afternoon showers or thunderstorms. Storms may contain strong gusty winds. High 89F. Winds SW at 15 to 25 mph. Chance of rain 50%.. Scattered showers and thunderstorms. Storms may contain strong gusty winds. Low 69F. Winds W at 10 to 20 mph. Chance of rain 50%. For military dependents wishing to attend colleges there are options. As a military dependent, I have been accepted to Lynn University in Boca Raton, Fla., where I will be majoring in journalism, using the Yellow Ribbon Program. The Yellow Ribbon Program is offered to people who receive the maximum benefit rate under the Post-9/11 GI Bill. This includes those who served 36 months active duty, Purple Heart recipients with an honorable discharge, children using transferred benefits if their sponsor is at the 100 percent level, and those discharged after 60 days with a service-related disability. Starting Aug. 1, 2022, both service members and transferee spouses at the 100 percent level will also be granted the Yellow Ribbon Program. Currently the Post-9/11 GI Bill only covers up to $23,671.94 per academic year. Starting Aug. 1, 2019, it will cover up to $24,476.79 each year according to the Veterans Admin...
