Interior of a human blood vessel. Something looks wrong, very wrong. Bacteria have entered the circulation, and the immunological system is reacting. All the alarms are on fire, while an army of white blood cells comes by, getting ready to unleash hell on the invaders. Suddenly, among these security agents, a neutrophil stands out. It […]
One of the most popular ideas within the new and fashionable transhumanism craze is that, in the future humans, will be able of reaching a kind of ‘immortality’ by decoding the information contained in your brain, ‘uploading’ it to some kind of memory device, and making it live on a computer (see, e.g., Seung 2012) […]
Major technological revolutions have occurred when the humankind has been able to harness natural resources, such as fire, electricity or nuclear energy. We are now in the verge of the so called second quantum revolution, that aims to harness two of the weirdest natural resources, coherence and entanglement. This is a tall order that calls […]
Diagnosis is one of the trickiest steps in disease management for many diseases, ranging from some types of cancer to rare diseases or neurodegenerative disorders, like Alzheimer’s for instance. Even though we have been hearing long about the disease, to date the only reliable diagnosis comes from a postmortem brain analysis and the finding of […]
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 […]
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 […]
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 […]
Topological insulators are electronic materials that have a bulk band gap like an ordinary insulator but have conducting states on their edge or surface. The conducting surface is not what makes topological insulators unique, but the fact that it is protected due to the combination of spin-orbit interactions and time-reversal symmetry. Researchers are chasing efficient […]
When we talk about nucleic acids we generally think of DNA and RNA that code for proteins, and when we talk about brain cells we tend to think of neurons and their nerve impulse transmission. However, it is not news that the functions of both non-coding genetic material and non-transmitting cells in the brain are […]
Syphilis is a sexually transmitted disease caused by a spirochete, a bacterium, Treponema pallidum subspecies pallidum . The main route of infection is by sexual contact but is also transmitted from the mother to the newborn in what is known as congenital syphilis. If syphilis is left untreated for years the treponema may invade the […]
