A new way to see the activity inside a living cell

Living cells are bombarded with many kinds of incoming molecular signal that influence their behavior. Being able to measure those signals and how cells respond to them through downstream molecular signaling networks could ...

Origins of the plantation system revealed

The first-ever investigation of an archaeological site on São Tomé is revealing the African island's involvement in the inception of the plantation economic model later exported to the Americas.

GOP wins battle of the bulb

Congress has dodged a government shutdown, agreeing to a $1 trillion spending bill that features a variety of rare compromises. Both Democrats and Republicans won some concessions, and it's too early to say who came out on ...

Fluorescing food dyes as probes to improve food quality

Food dyes can give cakes, candy and sodas brilliant colors of the rainbow. Now a team of food scientists at Rutgers University in New Jersey has found that food coloring may be able to play more than its traditional esthetic ...

Biologists develop new record bright red fluorescent protein

To understand why a cell divides, secretes hormones or transmits a signal to another cell, biologists often use a trick. They attach colored lights to the proteins of interest, so that they can follow the movements and interactions ...

Researchers outsmart the biological uncertainty principle

Anyone who has ever taken a group photo will be familiar with the problem: If everyone is constantly running around, it's almost impossible to get a sharp photo. Cell biologists who want to visualize molecular processes inside ...

Plasmonics enhances the sensitivity of smartphone microscopy

An international team of researchers from the University of California, Los Angeles and the Braunschweig University of Technology in Germany has developed an approach to enhance the sensitivity of smartphone-based fluorescence ...

Using sugar molecules to make cotton material glow

(Phys.org)—A team of researchers from Germany, Israel and Austria has developed a process for imbuing cotton fibers with material that glows under fluorescent light. In their paper published in the journal Science, the ...
