Researchers Developing More Powerful Solar Cells

Sure, Iowa has its share of rainy, snowy and cloudy days. But look out the window. “We have a lot of sunlight,” said Vikram Dalal as sunshine lit up a late-summer morning and the south-facing windows of his office at ...

Bitter Taste Identifies Poisons in Foods

Scientists at the Monell Chemical Senses Center report that bitter taste perception of vegetables is influenced by an interaction between variants of taste genes and the presence of naturally-occurring toxins in the vegetable. ...

Why Evolution Drives Some Cells to Altruism

Nature has been capitalizing on the benefits of a specialized labor force long before Henry Ford made it popular. New research suggests the same principles Ford used have driven the evolution of complex organisms.

Detecting Cancer with Silica Nanoparticles

Tumor necrosis factor-alpha is a widely accepted biomarker for cancer, but the minute amounts of this protein circulating in blood makes detecting the molecule and measuring its concentration accurately a technological challenge.

Project uses nanotubes to sniff out heavy metals

A team of researchers from Arizona State University and Motorola Labs has developed sensors based on carbon nanotubes, microscopically small structures that possess excellent electronic properties. In early tests, the new ...

Materials scientists tame tricky carbon nanotubes

Based on a new theory, MIT scientists may be able to manipulate carbon nanotubes -- one of the strongest known materials and one of the trickiest to work with -- without destroying their extraordinary electrical properties.

Evolutionary software to be released free of charge

New software developed by researchers at the University of Illinois at Urbana-Champaign allows scientists to more effectively analyze and compare both sequence and structure data from a growing library of proteins and nucleic ...
