Is there an evolutionary relationship to land-based lichens?
Researchers from China and the United States have found evidence of lichen-like symbiosis in 600-million-year-old fossils from South China. The previous earliest evidence of lichen was 400 million years old, discovered in Scotland. The discovery also adds to the scarce fossil record of fungi and raises new questions about lichen evolution.
Xunlai Yuan, a paleontologist with the Nanjing Institute of Geology and Palaeontology; Shuhai Xiao, assistant professor of geosciences at Virginia Tech; and Thomas N. Taylor, professor of ecology and evolutionary biology at the University of Kansas, report their finding in the May 13 issue of Science ("Lichen-Like Symbiosis 600 Million Years Ago").

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
