The OECD report on obesity in Spain published in 2014 (PDF) presented worrying data: 1-in-6 adults is obese and more than half are overweight, including obesity. The percentage of obesity has grown in the last years and its prevalence is linked to educational level: men with low studies are 1.6 times more likely to be […]
Like father like son. We have all heard it one time or another. The layman explanation to hereditary characters. Whether the cause is genetic inheritance or the effect of growing up in a certain environment, is quite something else. When talking about the origin of intelligence, there are always discussions. Even though there is undoubtedly […]
Specialized media sometimes publishes similar headlines to the title of the present article. For instance 1, 2, 3, 4, 5 or 6. They are all referred to deep learning, which is a part of artificial intelligence. However, if we get algorithms to work and achieve advanced intelligent applications, what is exactly not understandable? Deep learning […]
Aging is one of those topics mankind is always trying to understand, especially whether it can be reversed or stopped. With increasing age come not only alterations in appearance, but also associated changes like the degeneration of tissues such as muscles, bone and neural tissues or a higher predisposition for disease. In recent years, we […]
Organic chemistry is the science and the art of making carbon containing molecules. In these, carbon atoms may be linked by a single, double or triple bond to another carbon atom. Bonds are not more than the way we humans represent the sharing electrons between two atoms. In this regard, a single bond consists of […]
Unless you’ve been sitting in a cave for the last couple of years, you have probably heard about the new great promise of gene therapy: the gene editing CRISPR system. This new addition to the molecular biology toolbox is groundbreaking for what it implies. It does not simply “force in” a healthy copy of whichever […]
In social species, the dominant individual is often called the alpha. Depending on the species, the alpha may be a male, a female, both or a pair. The alpha individual usually presents a certain behavior: dominant, assertive, brash and usually has privileged access to food, mates, or best space, while the other members of the […]
Interfacial electron transfer constitutes the key step in the conversion of solar energy into electricity and fuels. Required for fast and efficient charge separation, strong donor−acceptor interaction is typically achieved through covalent chemical bonding…or not. Experiences with donor−acceptor molecular diads and triads, conjugated polymers, and DNA, leads to the expectation that a covalent bonding is […]
Testosterone is the primary male sex hormone and, in men, it plays a key role in the development of male reproductive tissues such as the testis and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. Testosterone increases in heterosexual men after having […]
Extended and refined by Bloch and others during the 1930s, Bloch’s theory, known as the band theory of solids, accounts very well for the conducting behaviour of materials. When atoms are joined together into a crystal, each of the individual quantum states of the atoms joins with the corresponding states in other (identical) atoms in […]
