There may be a genetic connection between some mental health disorders and type 2 diabetes. In a new report, scientists show that a gene called “DISC1,” which is believed to play a role in mental health disorders, such as schizophrenia, bipolar disorder and some forms of depression, influences the function of pancreatic beta cells which produce insulin to maintain normal blood glucose levels.

Plasticity of the brain, what does that even mean? Well the good news is that it isn’t just a marketing ploy, the brain needs to be “plastic” because we need to be able to adapt. Frankly speaking, the brain still has a lot to learn about itself. Scientists at the Virginia Tech Carilion Research Institute have made a key finding of the striking differences in how the brain’s cells can change through experience.

As discussed before, Zika Virus (ZIKV) is an emerging arbovirus, spread by Aedes Agypti and Aedes albopictus, which was first isolated in 1947 in Uganda from a Macaca monkey with the first human case being detected in Nigeria (1954). In subsequent decades sporadic cases linked to ZIKV have been reported in Africa and Asia, with a first epidemic reported in 2008 (Yap/Federated States of Micronesia) and a larger one in French Polynesia and Oceania 2013-2014 with the first cases in the Americas wer........

A potential case of data manipulation has been uncovered in a psychology paper. The suspect article, Why money meanings matter in decisions to donate time and money, came out in 2012 from University of Arizona psychologists Promothesh Chatterjee, Randall L. Rose, and Jayati Sinha.
This study fell into the genre of 'social priming', specifically 'money priming'. The authors reported that making people think about cash reduces their willingness to help others, while thinking of credit cards has... Read more »
Last week a fascinating study appeared in PNAS on melody cognition in sparrows (Sturnus vulgaris).

This was the question faced by the participants in a rather extraordinary series of studies described in a new paper from Illinois psychologists Randy J. McCarthy and colleagues. In total, 1081 parents with children aged under 18 were presented with an outline of a person, and asked to imagine that it was their own child. They were told to think of a time when their child made them angry. Finally, they were asked how many pins they would like to stick into the "doll" in or... Read more »

Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton. The study found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.

Although lizards mostly scurry on all fours, certain species can run on two legs when the mood strikes. What's the benefit to this human-like running style? For one thing, it seems to let lizards get over obstacles without slowing down. They just have to make sure not to tip over.

A lot of has been written about how focusing too much on materialistic ambitions, at the expense of relationships and experiences, can leave us miserable and unfulfilled. In a new paper published in Social Psychological and Personality Science, a team of psychologists at the University of British Columbia in Canada argue that there's another important distinction to be made – between how much we prioritise time versus money. Those who favour time tend to be happier, possibly because this frees........ Read more »

Genes could help in determining whether a person likes to rise early in the morning or not.
