Non-invasive DNA-labeling tool opens doors for new research

Dutch researchers have developed a new tool to label DNA for studying chromosomes in live cells. The tool is non-invasive and can be applied in culture but also in living organisms, such as zebrafish embryos. The team published ...

Color-changing indicator predicts algal blooms

Murky green algal blooms are more than a major eyesore; they reveal that a body of water could be unsafe for swimming or drinking. Currently, however, there isn't an effective warning system for impending blooms. Now, researchers ...

Making short-wave infrared light visible with a single component

Infrared (IR) light is invisible to humans. However, some animals, such as rattlesnakes or bloodsucking bats, can perceive IR radiation and use it to find food. But even for humans, the ability to see in the short-wave IR ...

Improved fluorescent amino acids for cellular imaging

New research conducted by researchers in the lab of Penn's E. James Petersson in collaboration with Oregon State University and the University of Washington describes how proteins in living cells can be engineered to include ...

Molecular scales on biological membranes

Cellular processes on membranes are often fast and short-lived. Molecules assemble briefly, separate again, interact with different partners and move along or through the membrane. It is therefore important to not only study ...
