…burn easily in air, fluoresce under UV light and react with most nonmetals. But then lanthanides inexplicably fell out of popularity in the 1970s. Now Almutairi is taking up the mantle to explore how lanthanides do one special thing: convert low-energy light to high-energy light. She has two people in…

Biologists have long known that organisms from bacteria to humans use the 24 hour cycle of light and darkness to set their biological clocks. But exactly how these clocks are synchronized at the molecular level to perform the interactions within a population of cells that depend on the precise timing…

In an example of life imitating art, biologists and bioengineers at UC San Diego have created a living neon sign composed of millions of bacterial cells that periodically fluoresce in unison like blinking light bulbs.

Amyloid plaques found in the retinas of eyes may be an indicator of similar plaques in the brain, a hallmark of Alzheimer’s disease, and may provide a more visible biomarker for detecting disease risk.

Scientists at the University of California, San Diego, have designed tiny spherical particles to float easily through the bloodstream after injection, then assemble into a durable scaffold within diseased tissue.

…Emmanuel Theodorakis’s lab studying fluorescent molecules that can be used for detection of amyloid plaques, which are linked to Alzheimer’s disease. Today, Alzheimer’s disease is clinically diagnosed once cognitive symptoms become evident. The Theodorakis lab is working to develop diagnostic molecules to identify the disease in its initial stages—even before…

…genes attached to green fluorescent proteins can be viewed under an ultraviolet light using a dark box with viewing holes. Physics students meanwhile will demonstrate the many uses of liquid nitrogen in cooling materials. The Jacobs School of Engineering’s undergraduate students will display the hardware they use to launch balloons…

…as a brightfield and fluorescent microscope as well as a spectrophotometer to examine everything from blood cells to bacteria. Traditional two-in-one microscopes don’t historically include spectroscopy and can cost more than $50,000. The students are now on their third prototype for the microscope and estimate there will be at least…

…elucidate how the Green Fluorescent Protein works. He also extended the protein’s palette beyond green to a rainbow of colors, allowing scientists to assign different colors to various proteins and cells and follow several different biological processes at the same time.
