Many popular sites, such as Wikipedia and Tripadvisor, rely on public participation to gather information — a process known as crowd data sourcing. While this kind of collective intelligence is often valuable, it is also fallible, and policing such sites for inaccuracies and offensive material is a costly undertaking. But not for long.

The new story of stuff: Can we consume less?
Will rich societies start consuming less? Could wealth go green? Might parsimony become the new luxury? Heresy, surely, you would say. But it might just be possible. Take Britain. A new study finds that the country that invented the industrial revolution two centuries ago reached “peak stuff” between 2001 and 2003. In the past decade, […] … learn more→
Baby talk – do mums just know?
James Cook University speech pathology honours student Vicki Williams wants to find out what first time mums know about speech and language development in young children. “The early years are so important” she said. “Parents are the most influential people in a young child’s life and how they interact with their child influences their development, […] … learn more→
Fungi: Another tool in bacteria\’s belt?

Now researchers at Tel Aviv University have discovered that the two organisms enjoy a mutually beneficial relationship to aid them in that movement — and their survival. Fungal spores can attach themselves to bacteria, \”hitching a ride\” wherever the bacteria travel. And while this allows them to travel further […] … learn more→

Durban: where success will mean the avoidance of failure
Global climate policy reached a turning point at the 2009 Copenhagen conference. Expectations of a binding global climate treaty were dashed, but instead all major countries made unilateral pledges to cut or restrain their greenhouse gas emissions. 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
Among young American adults, relationships between white men and minority women move into sexual intimacy and from sex to cohabitation significantly faster than white-white couples or minority-minority pairings, reports a new study by a Cornell demographer. 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→
