Halos of Clay Can Preserve Billion-Year-Old Microbes
New discovery could help scientists unearth more ancient microbial fossils and shed light on some big questions about early life on Earth.

Plants are marvelous chemists, as the gardenia's DNA shows
Plants are some of nature's most extraordinary chemists. Unlike animals, they can't run from predators or pathogens. They can't uproot themselves to spread their seeds.

The exhaust gas from a power plant can be recovered and used as a raw reaction material
A Japanese research group developed a new technology that can drastically conserve the energy used to capture CO2 from gases exhausted from a concentrated source such as thermal power plants. With this technology, namely H2 stripping regeneration technology, combustion exhaust gas can be replaced by CO2/H2 gas at lower temperatures than those used in conventional technology.
