On the trail of the clever snail

Animals, like humans, excel at some tasks but not others according to a new study published in the journal Scientific Reports. Researchers from the Universities of Exeter and Aberystwyth used pond snails to investigate learning and memory. They found that if an individual is good at forming memories about food they are poor at forming memories related to predator threat and vice versa. —> Read More

Linking superconductivity and structure

Superconductivity is a rare physical state in which matter is able to conduct electricity — maintain a flow of electrons — without any resistance. It can only be found in certain materials, and even then it can only be achieved under controlled conditions of low temperatures and high pressures. New research hones in on the structural changes underlying superconductivity in iron arsenide compounds — those containing iron and arsenic. —> Read More

Glacier changes at the top of the world

If greenhouse-gas emissions continue to rise, glaciers in the Everest region of the Himalayas could experience dramatic change in the decades to come. A team of researchers in Nepal, France and the Netherlands have found Everest glaciers could be very sensitive to future warming, and that sustained ice loss through the 21st century is likely. The research is published May 27 in The Cryosphere, an open-access journal of the European Geosciences Union. —> Read More

False breast cancer alarm has negative impact on health

The psychological strain of being told that you may have breast cancer may be severe, even if it turns out later to be a false alarm. This is the finding of new research from the University of Copenhagen, which has just been published in the scientific journal Annals of Family Medicine. Researchers call for improving screening accuracy, thus reducing the number of false-positive mammograms. —> Read More
