It seems that we are definitely heading towards the bio-based society, a new way of interacting with the environment where fossil fuels won’t be needed anymore and “ more natural ” processes for producing energy, food and materials will prevail. Remarkably, this bio-turn often involves highly advanced biotechnology and strict competitive targets, both facts that […]
Fernando Nottebohm was born in Buenos Aires in 1940, a second generation Argentine. Animals fascinated him since he was a child and he always wanted to understand how birds sing. After moving to the United States, he began to investigate the bird behavior and he found, using unilateral denervation of the syrinx, song handedness, i.e […]
Back in 2001, the Human Genome Project gave us a complete readout of our DNA, unraveling that magic sequence of As, Gs, Cs, and Ts that contained all the information for making one of us. Thanks to that, we now know that in that sequence only 1.5% has information to make proteins, a fact that […]
The way we approach pain therapies doesn’t differ from the ones taken for other diseases. The aim is to look for molecular targets, which can be suitable for chemical intervention thoroughly assessing both efficacy and safety profiles for the drug, issues that are addressed throughout various stages of clinical trials. In the specific case of […]
The human brain continues its development postnatally. It is a long process that extends throughout, at least, the first two decades of life. Along these years, environmental factors influence brain functions and, not surprisingly because of its high plasticity, brain structure. Among the variables that may affect the cognitive development is the socioeconomic status. Three […]
Sensations which seem to come from limbs that had been amputated are called «phantoms». Most limb amputees report awareness of a phantom limb, i.e., the perceived presence of the missing arm or leg. Phantom sensations may also occur after the removal of body parts other than the limbs, e.g. after amputation of the breast, extraction […]
Since its discovery in 2003, graphene has become one of the “materials of the future”, with applications ranging from tissue engineering to energy storage. Recently, a paper published in Oncotarget by researchers at the University of Manchester has shown its potential in anti-cancer therapy, in addition to its already known applications in medicine as a […]
Tracking back human civilization there are evidences of dog domestication as far as 10,000 years ago. During this time, the ancient wolves’ genome evolved to give rise to the domestic dog that gradually adapted to human habitat as many organic functions were selected in detriment of others. Dogs have similar circadian rhythms, have adapted to […]
In 1968, the Canadian psychologist from McGill University Ronald Melzack described pain as being multidimensional and complex, with sensory-discriminative, affective-motivational and cognitive-evaluative components . Such definition may be a hint as to why the biological meaning of pain has been an (to date) unceasing matter of debate since Aristotle, who thought pain is just a […]

Some jellyfish species are beautifully fluorescent in the dark ocean, emitting light from different parts of their bodies in a process that is thought to help them to warn off predators. The molecular biology behind this process of glowing is possible thanks to one of the most famous proteins in molecular biology, the green fluorescent […]
