Software to protect the world's most endangered species

By combining genetic and environmental databases, researchers at EPFL are seeking to help biologists identify more accurately the animal and plant species most exposed to climate change, in order to develop appropriate conservation ...

Why Noah's ark won't work

A Noah's Ark strategy will fail. In the roughest sense, that's the conclusion of a first-of-its-kind study that illuminates which marine species may have the ability to survive in a world where temperatures are rising and ...

Is sex primarily a strategy against transmissible cancer?

One of the greatest enigmas of evolutionary biology is that while sex is the dominant mode of reproduction among multicellular organisms, asexual reproduction appears much more efficient and less costly. However, in a study ...

Trap-and-release accelerates study of swimming ciliated cells

Researchers at Washington University in St. Louis have been studying cilia for years to determine how their dysfunction leads to infertility and other conditions associated with cilia-related diseases. Now, they will be able ...

Intelligent algorithms for genome research

Although the importance of machine learning methods in genome research has grown steadily in recent years, researchers have often had to resort to using obsolete software. Scientists in clinical research often did not have ...

Climate change has long-term impact on species adaptability

Historic climate change events can have a lasting impact on the genetic diversity of a species, reveals a new study published in Current Biology. This unexpected finding emerged from an analysis of the alpine marmot's genome.

Genetic variation

Genetic variation, variation in alleles of genes, occurs both within and among populations. Genetic variation is important because it provides the “raw material” for natural selection.
