Author: Ramón Muñoz-Chápuli has been Professor of Animal Biology in the University of Málaga until his retirement. He has investigated for forty years in the fields of developmental biology and animal evolution. Hummingbirds are fascinating animals. They are the only birds able to true hovering and backward flight. This ability allows them to collect nectar […]

Beyond lithium: magnesium rechargeable batteries

ChemistryMaterials

By César Tomé

Lithium-ion batteries have remained unrivalled in terms of overall performance for several applications, as evidenced by their widespread use in everything from portable electronics to cellular base stations. However, they suffer from some important disadvantages that are difficult to ignore. For one, lithium is rather expensive, and the fact that it is being mined at […]

We, humans, have evolved pretty big brains compared to other mammals, and even compared to our primate cousins. Recent research seems to have found the reason for the higher number of neurons in our brains (about 86 billion). It appears that a single gene is responsible for our bigger brain. The Neanderthals are an extinct […]

Surfaces are at the frontier of every solid. They provide versatile supports for functional nanostructures and mediate essential physicochemical processes. Intimately related to two-dimensional materials, interfaces and atomically thin films often feature distinct electronic states with respect to the bulk, which is key to many relevant properties, such as catalytic activity, interfacial charge-transfer, and crystal […]

Could we feed a city on Mars? This question is central to the future of space exploration and has serious repercussions on Earth too. To date, a lot of thought has gone into how astronauts eat; however, we are only beginning to produce food in space. Space launches are quite expensive. And with the growing […]

Pain and autism

Pain and autism

Neurobiology

By José Ramón Alonso

Pain is a complex sensation that is mediated by both the peripheral and central nervous systems. In the peripheral nervous system, pain signals are generated by nerve fibers called nociceptors that respond to harmful stimuli. These signals are then transmitted to the brain through the spinal cord, where they are processed and interpreted as pain […]

By DIPC

Nonlinear optics is concerned with the optical properties of matter subjected to intense electromagnetic fields. For nonlinearity to manifest itself, the external field should not be negligible compared to the internal fields of atoms and molecules of which the matter consists. Lasers are capable of generating external fields sufficiently intense for nonlinearity to occur. Actually […]
