Cell signalling is the mechanism by which cells communicate with each other and with their environment. Stimuli, which are generally chemical, are transmitted via a signalling cascade to effector molecules that orchestrate the appropriate response. Signalling pathways are not isolated but they rather form a complex network of biochemical reactions that regulate processes such as […]
Since the discovery that graphene, the two dimensional carbon allotrope, can be isolated and incorporated into electronic devices intense research efforts have been triggered. Driving forces behind the experimental and theoretical studies of graphene are, e.g., the exceptional electronic properties, in particular the high electron mobilities, the long spin coherence lengths and the possibility to […]
There is a word everybody fears and that is because when you listen to it out loud, it could be too late. Even though we have likely coexisted with cancer since complex multicellular organisms evolved, to us human beings, it just seems the number of cases keeps growing every year. Sadly, that seems to be […]
We know that incident light can provoke a strong optical response in metallic nanostructures due to the excitation of resonant plasmonic modes, i.e, the electrons in the metal become excited by the photons in the incident light and oscillate collectively. Plasmonic nanoparticles can significantly modify the optical properties of nearby organic molecules and thus present […]

The Pioneer plaques are a pair of gold–anodized aluminium plaques which were placed on board the 1972 Pioneer 10 and 1973 Pioneer 11 spacecraft, featuring a pictorial message, in case either Pioneer 10 or 11 is intercepted by extraterrestrial life. The plaques show the nude figures of a human male and female along with several […]

Antimicrobial resistance is a complex problem that contributes to health and economic losses worldwide. Resistance to antimicrobial therapies reduces the effectiveness of current drugs, leading to increased morbidity, mortality, and health care expenditure. Because globalization increases the vulnerability of any country to diseases occurring in other countries, resistance presents a major threat to global public […]
Diabetes is a disease typically associated with old age, especially when speaking of type 2, characterized for insulin resistance, and associated with obesity and therefore, more likely to occur in old age. A recent couple of papers published in Cell and Science Translational Medicine point to the healing potential of a fasting-mimicking diet for resetting […]
Graphene is one of the most promising materials for nanoelectronics owing to its unique Dirac cone-like dispersion of the electronic state and high mobility of the charge carriers. We all know that already, provided we are a little bit interested in condensed matter physics. But the point is that, in order to facilitate the implementation […]
A key aspect of our effort to overcome autism is to get a quick, reliable and early diagnosis. Typical signs such as difficulty in making eye contact or following the mother’s pointing gesture are usually observed after the age of two years and we also have the problem of the natural variability that exists in […]
15% of human cancers worldwide may be attributed to viruses, 1 with both DNA and RNA viruses being capable of causing the disease. Epstein-Barr virus, human papilloma virus, hepatitis B virus, and human herpes virus-8 are the four DNA viruses capable of causing the development of human cancer, whereas human T lymphotrophic virus type 1 […]
