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 ...

Study unlocks secrets of an elusive genome compartment

Although much of the human genome has been sequenced and assembled, scientists have hit roadblocks trying to map unassembled regions of DNA that consist mostly of repetitive sequences, including the centromere.

Biochemists untangle mysteries of cellular form, function

The complex inner workings of cells, from their architecture to their signaling, underlie much of multicellular organic life. How are they built? How do their proteins interact? And most crucially, how can understanding these ...

Scientists crack the code to regenerate plant tissues

Plant regeneration can occur via formation of a mass of pluripotent cells. The process of acquisition of pluripotency involves silencing of genes to remove original tissue memory and priming for activation by external input. ...

Plant immunity cut to size

An international team based in Ghent, Belgium (VIB-UGent Center for Plant Systems Biology) and Basel, Switzerland (University of Basel), found a link between a class of enzymes and immune signals that is rapidly triggered ...

Students go to ends of the Earth to dig up climate history

Between 256 million and 335 million years ago, the landmasses of the Southern Hemisphere were squished together in a super continent called Gondwana. Gripped in the cold throes of an ice age, glaciers moved slowly across ...
