Changing semiconductor properties at room temperature

It's a small change that makes a big difference. Researchers have developed a method that uses a one-degree change in temperature to alter the color of light that a semiconductor emits. The method, which uses a thin-film ...

Nano-decoy lures human influenza A virus to its doom

To infect its victims, influenza A heads for the lungs, where it latches onto sialic acid on the surface of cells. So researchers created the perfect decoy: A carefully constructed spherical nanoparticle coated in sialic ...

CASE coconut building panels on display in Ghana

Building panels made of upcycled coconut husks made a statement at the Chalewote Street Art Festival in Accra, Ghana, this summer. A kiosk constructed of the panels was featured in an online video report by MeshTV in Ghana.

Calculating the role of lakes in global warming

As global temperatures rise, how will lake ecosystems respond? As they warm, will lakes—which make up only 3 percent of the landscape, but bury more carbon than the world's oceans combined—release more of the greenhouse ...

Was RNA the original prebiotic molecule?

Where did life begin—in a shallow lagoon, or in a vent of superheated water spewing from the ocean floor? If we knew, we might know where to look for life elsewhere in the universe. The "RNA World" hypothesis, which suggests ...

A new approach to building efficient thermoelectric nanomaterials

By doping a thermoelectric material with minute amounts of sulfur, a team of researchers has found a new path to large improvements in the efficiency of materials for solid-state heating and cooling and waste energy recapture. ...

Historic fossils find new life telling the story of ancient proteins

A few snippets of protein extracted from the fossil of an extinct species of giant beaver are opening a new door in paleoproteomics, the study of ancient proteins. Ancient proteins can be used to place animals on the evolutionary ...

Discovery of rules for CRISPR advance metabolic engineering

Discovery of rules that govern a variation of the CRISPR/Cas9 gene-editing method makes it possible to use living cells to manufacture valuable metabolic compounds like pharmaceuticals and nutraceuticals. Researchers at Rensselaer ...
