In ‘Chemistry Essentials for Dummies‘, John T. Moore writes:
Matter is anything that has mass and occupies space. It can exist in one of three classic states: solid, liquid, and gas. When a substance goes from one […]
In 1928, Santiago Ramón y Cajal, the founder of modern neuroscience, wrote that the brains of adult humans never make new neurons. “Once development was ended,” he proclaimed, “the founts of growth and regeneration … dried up irrevocably. In the […]
We usually think of crystals as composed of different atoms in certain proportions, this proportion being the molecular fórmula that represents the crystal. However, it is not surprising that any molecule could be the basis of a crystal structure, whether […]
Graphene is a two-dimensional allotrope of carbon made of hexagons. It is a zero-gap semimetal with a tiny overlap between valence and conductance bands. Since the isolation of graphene in 2004, considerable interest has been paid to exploring its […]
Doñana National Park, at the South-western coast of Spain, is known to host several species of wading birds. These piscivorous birds nest in colonies in the neighboring woodlands, formed by cork oaks, close to the marshals where they feed. Ever […]
Estrogens are steroid hormones affecting several organs including mammary glands. More precisely, these glands exert their action by means of estrogens through the estrogen receptor (ER), a transcription factor belonging to the family of nuclear receptors. So far, two […]
We usually think of nature as existing completely independently of us and possessing a definite reality and behaviour even when we are not observing it. For instance, you assume that the world outside of the place where you are now […]
Two of the hot topics in science an technology nowadays are related to Computer Science. They are Artificial Intelligence (AI) and Quantum Computing (QC). AI is a really old field, as humanity has dreamed of having autonomous machines for decades. […]
A language is a communication system that is based on the development, acquisition, maintenance and use of a series of vocal tools that allow the exchange of information between different people.
All healthy human beings, with a normal development, […]
The wave–particle dualism is a fundamental aspect of quantum mechanics. But, in order to explore this dualism properly and what it means for our image of atoms, it is necessary to review some ideas of probability.
In some situations, no […]
