Researchers at Delft University of Technology have demonstrated for the first time that nano-antennas can enhance the fluorescence of proteins in living human and other mammalian cells. Scientists already use smart fluorescent ...
The devastating floods that have swept through the Nepal–Tibet border region are first and foremost a human tragedy. Hundreds of people have died or remain missing. But as scientists begin to reconstruct what happened, the ...
When Ashley Dayer was walking on the beach with her 8-year-old son recently, he stopped her before she got too close to a group of shorebirds. "Momma, stop. We have to walk around the shorebirds," he told her. Dayer smiled. ...

A new study examining tropical cyclone forecasts in the Atlantic Ocean suggests that artificial intelligence could provide valuable additional guidance for predicting when and where tropical disturbances may develop into ...
Tablets and computers have become crucial school supplies for many students. But the same devices children use to read text, write essays, solve math problems or research history projects can also offer distractions in the ...
Lakes play an important role in capturing and storing carbon, which accumulates in their sediments. But the amounts they can absorb have varied considerably over time. Jean-François Lapierre, a professor in the Department ...
For decades, light has been used to understand the molecular structures of matter. A sample is irradiated with light, and measurements determine the wavelengths at which it is absorbed. Since each molecule absorbs light at ...
