EAST LANSING, Mich. --- Intelligence -- and not just relentless practice -- plays a significant role in determining chess skill, indicates a comprehensive new study led by Michigan State University researchers.

The research provides some of the most conclusive evidence to date that cognitive ability is linked to skilled performance -- a hotly debated issue in psychology for decades -- and refutes theories that expertise is based solely on intensive training.

A new study by psychologists from the University of Liverpool and the University of Ontario Institute of Technology (UOIT) reveals that collaborating in a group to remember information is harmful.

The research, conducted by Dr Craig Thorley, the University's Department of Psychological Sciences, and Dr Stéphanie Marion, from UOIT's Faculty of Social Science and Humanities, statistically analysed 64 earlier collaborative remembering studies and found that groups recall less than their individual members would if working alone.

The same study also found that collaborative remembering boosts later individual learning: people who previously recall in a group remember more than those who do not.

With one in two Australian children reported to have tooth decay in their permanent teeth by age 12, researchers from the University of Sydney believe they have identified some nanoscale elements that govern the behaviour of our teeth.

Material and structures engineers worked with dentists and bioengineers to map the exact composition and structure of tooth enamel at the atomic scale.

Using a relatively new microscopy technique called atom probe tomography, their work produced the first-ever three-dimensional maps showing the positions of atoms critical in the decay process.

COLUMBIA, Mo. - Arts and cultural nonprofit organizations promote arts appreciation and strengthen communities by providing a wide range of arts programs in music, theater, visual arts and dance. These organizations rely on donations to exist. One way that the nonprofit sector currently measures these organizations' successes is by the number of people who attend their programs. However, new research from the University of Missouri finds no evidence to support the idea that donors are influenced by high attendance numbers; in fact, large audience numbers may actually lead to fewer donations.

A new study reveals that adverse drug reactions in newborns and infants may be under-reported.

For the study, investigators analyzed 2001-2010 information from the UK Medicines and Healthcare products Regulatory Agency, which runs a national spontaneous reporting system to collect suspected adverse drug reaction data.

The researchers found that spontaneous reports alone are not currently generating required data, and important safety messages from the regulator do not match reporting patterns. Additional reporting strategies will be required to improve the quantity and quality of information on suspected adverse drug reactions in young children.

A group of James Cook University scientists led by Emeritus Professor Ross Alford has designed and built an inexpensive incubator that could boost research into how animals and plants will be affected by climate change.

JCU's Sasha Greenspan said the team designed and built small, inexpensive, low-energy-consumption chambers that allow small organisms to grow under very precisely controlled temperature regimes.

"These are an important advance because they make well replicated, realistic experiments possible," said Ms Greenspan.
