Oaks adapt drought resistance to local conditions

As climate change brings an increase in the frequency and severity of droughts, forest dieback is a key cause for concern: forests act as reservoirs of biodiversity and also allow vast amounts of carbon to be stored, reducing ...

Designing soft materials that mimic biological functions

Northwestern Engineering researchers have developed a theoretical model to design soft materials that demonstrate autonomous oscillating properties that mimic biological functions. The work could advance the design of responsive ...

Mouse sperm generated in rats

Making gametes such as sperm and eggs from pluripotent stem cells—primitive cells that can make all the tissues—greatly contributes to efficient reproduction of livestock animals and future assisted reproductive medicine. ...

Species

In biology, a species is:

There are many definitions of what kind of unit a species is (or should be). A common definition is that of a group of organisms capable of interbreeding and producing fertile offspring, and separated from other such groups with which interbreeding does not (normally) happen. Other definitions may focus on similarity of DNA or morphology. Some species are further subdivided into subspecies, and here also there is no close agreement on the criteria to be used.
