Nowadays, most important news concerning science focuses on applicability ; if you read a newspaper or magazine you will see news about how a new drug or appliance can be applied in the fight against disease, hunger, etc. However, behind the results lies a lot of hard work on the part of different group s- […]
Our immune system comprises a great variety of cell types and each of these groups is specialized in separate and defined actions. Macrophages play an essential role within this defence system by enhancing the immune response. In particular, they are in charge of “swallowing” (technically speaking, fagocyting) waste products, foreign materials and microorganisms. In addition […]
During the last decades, the electronics industry has been very successful in pushing forward the advancement of electronic building blocks, but the limit of silicon-based electronic devices especially in terms of miniaturization are almost reached. There are many ideas how to overcome this problem, for example, by adding functionality based on approaches originating from molecular […]
The scattering of conduction electrons in metals owing to impurities with magnetic moments is known as the Kondo effect, after Jun Kondo, who analysed the phenomenon in 1964. This scattering increases the electrical resistance and has the consequence that, in contrast to ordinary metals, the resistance reaches a minimum as the temperature is lowered and […]

We all know that the main role of DNA is the storage of genomic information leading to the biosynthesis of proteins via diverse forms of RNA. In turn, proteins play multiple roles in living systems, catalysis being among the most important ones. These are the standard functions that we may find in any general chemistry […]
A quantum dot is a nanometric crystalline structure of semiconductor materials. In a quatum dot electrons are confined in a region of space, thus creating a well defined structure of energy levels that depends very much on the size and shape of the quantum dot. This structure resembles that of atoms, that is why sometimes […]
The immune system is a complex network that recognises foreign substances in the body. When it detects an alien substance (antigen), it creates antibodies to attack and destroy it. This system protects vertebrates against viruses, bacteria, fungi and other parasites, and is the reason for the “rejection” after organ transplants. When we have cancer, our […]
The ability to trap and control particles with the help of well-controlled electromagnetic fields has led to revolutionary advances in the fields of biology, condensed- matter physics, high-precision spectroscopy, and quantum information, enabling unprecedented control both in the study of isolated single particles as well as in few and many-body systems subject to controlled and […]
W orld Health Organization (WHO) established the recognition of obesity as a disease in 1948, but it was not until the last decade of the 20th century that people began to gain awareness of overweight-derived health problems. A decade ago and based on worldwide data indicating that 40 % of global adult population were overweight […]
A dielectric is a nonconductor of electric charge in which an applied electric field causes a displacement of charge but not a flow of charge. Light propagation through a dielectric medium is determined by the spatial distribution of the material. Photons scatter at local variations of the refractive index. Therefore, how ordered the medium is […]
