Crowd-sourcing — accurately!

Many popular sites, such as Wikipedia and Tripadvisor, rely on public participation to gather information — a process known as crowd data sourcing.

Durban: where success will mean the avoidance of failure

Global climate policy reached a turning point at the 2009 Copenhagen conference.

That was probably a more significant outcome than a binding, but weak, agreement might have been. What counts […] … learn more→

Race plays a role in the pace of some romances

Despite rising intermarriage rates in recent decades — a sign of declining social distance between race groups in the […] … learn more→

A new model for understanding biodiversity

Researchers develop a unified theory of ecosystem change by combining spatial modelling and food web analysis. Animals like foxes and raccoons are highly adaptable. They move around and eat everything from insects to eggs. They and other “generalist feeders” like them may also be crucial to sustaining biological diversity, according to a new study published […] … learn more→
