African mole rats are insensitive to many kinds of pain. As an international research team led by the MDC's Gary Lewin reports in Science, this characteristic has allowed mole rats to populate new habitats. Thanks to a genetic ...

3-D technology looks into the distant past

Researchers from the University of Tübingen and their colleagues from Switzerland have studied hundreds of fossil carp teeth for the first time using 3-D technologies. In 4 million-year old lake sediments from what is now ...

Warmer water linked to higher proportion of male flounder

If southern flounder live in warmer water during a critical window of early development, a higher percentage become male—more than 90 percent in some cases—research from North Carolina State University found. Having a ...

Latitudinal gradient of plant phylogenetic diversity explained

Why are there so many species in the tropics? For centuries, scientists have been searching for the causes of the latitudinal gradient in species diversity—a pattern that has been documented for most groups of living species, ...
