A study on human behavior has revealed that 90% of the population can be classified into four basic personality types: Optimistic, Pessimistic, Trusting and Envious. However, the latter of the four types, Envious, is the most common, with 30% compared to 20% for each of the other groups.

This is one of the main conclusions of a study recently published in the journal, Science Advances by researchers from Universidad Carlos III de Madrid, together with colleagues from the universities of Barcelona, Rovira i Virgili and Zaragoza. The study analyzed the responses of 541 volunteers to hundreds of social dilemmas, with options leading to collaboration or conflict with others, based on individual or collective interests.

Scientists at the University of Glasgow have made a second significant breakthrough in the treatment of chronic myeloid leukaemia – using precision medicine to kill more than 90% of chronic myeloid leukaemia (CML) stem cells. The results are published today in the high impact journal Cancer Discovery.

CML is a rare form of blood cancer. An individual gets CML when normal blood stem cells are turned into leukaemic stem cells, or CML stem cells. These CML stem cells then produce large numbers of leukaemic cells which, if left untreated, is fatal.

With one billion stars mapped in a thousand days, European researchers have shown that they are not afraid to tackle the most daunting tasks. The work was carried out by 450 researchers from 25 European countries, including around a hundred scientists from France, mainly at the CNRS, Observatoire de Paris and Observatoire de la Côte d’Azur[1], with major participation by the French space agency CNES. Using the Gaia spacecraft, launched on 19 December 2013, scientists have catalogued the position of 1.15 billion stars, and in addition measured the velocity and distance of two million of them relative to the Sun. ESA[2] and the European consortium DPAC[3] are releasing the mission's first findings on September 14.

The following factors facilitate the formation of putatively toxic structures in the neuronal nuclei of Alzheimer’s patients.

Spherical structures in the nucleus of nerve cells, so-called nuclear spheres, are suspected to trigger Alzheimer’s disease. A team headed by Dr Thorsten Müller from the research group Cell Signaling in Neurodegeneration has for the very first time demonstrated the presence of the presumably toxic protein aggregates in the human brain. The researchers from Ruhr-Universität Bochum have published their article in the journal Neurobiology of Aging.

Number of nuclear spheres higher in Alzheimer’s patients

Visualization was enabled by designing a new artificial magnetic material. The finding means remarkable possibilities to materials research.

Researchers at Aalto University and Lawrence Berkeley National Laboratory have demonstrated that polaron formation also occurs in a system of magnetic charges, and not just in a system of electric charges. Being able to control the transport properties of such charges could enable new devices based on magnetic rather than electric charges, for example computer memories.

The sense of touch may play a more crucial role in autism spectrum disorder (ASD) than previously assumed. The main findings of the doctoral research of Eliane Deschrijver, which are now published, show that individuals with ASD may have difficulties to determine which tactile sensations belong to the action of someone else.

ASD: social problems and sensory sensitivities

Many individuals with ASD are over- or undersensitive to sensory information. Some feel overwhelmed by busy environments such as supermarkets, others are less sensitive to pain, or dislike being touched.
