An earworm is a melody that arises spontaneously in the mind, perhaps after having heard it only once, and gets “stuck” in the head for hours or days. It is also called brainworm, catchy music, repetition of musical images, involuntary musical imagery and stuck song syndrome. We may come to feel that the tune is […]
Ancient star yields new idea about origin of heavy elements A magnetorotational hypernova explosion, rather than a neutron star merger, probably created SMSS J2003-1142, an ancient star in the halo of the Milky Way, according to David Yong and Gary Da Costa, who published their team’s findings in Nature. “[N]eutron star mergers, together with magnetorotational […]
Tetrapyrroles,“the pigments of life”,are key molecules for the metabolism of living organisms, supporting functions of vital importance such as electron transport, light-harvesting and oxygen reduction. Within this family of compounds, porphyrins are organic pigments characterized by the possesion of a cyclic group of four linked nitrogen-containing rings called porphyrin, the nitrogen atoms of which are […]
“Plant more trees” is often the first idea that comes to mind when we think about how to prevent further climate change or at least adapt to its impacts. There are good reasons for this. Multiple studies have shown that as well as trees being a fantastic way to store carbon dioxide, they offer other […]
When hungry, not only our bodies long for food, our brains do too. And it appears that when it comes to social interaction, a similar thing happens. Social deprivation leads to a brain angry for social contact. A recent study [Livia Tomova et al (2020) Acute social isolation evokes midbrain craving responses similar to hunger […]
Deep Space Atomic Clock aces test Researchers say the Deep Space Atomic Clock has outpaced other kinds of space clocks, heralding what it could do for the future of navigation in space. The atomic clock, which has been orbiting Earth in a satellite for about two years in its first test run, uses ions to […]
It is very difficult to obtain exact solutions to systems involving interactions between more than two bodies, using either classical mechanics or quantum mechanics. To understand the physics of many-body systems, it is necessary to make use of approximation techniques or model systems that capture the essential physics of the problem. T he complexity of […]
IQ is often hailed as a crucial driver of success, particularly in fields such as science, innovation and technology. In fact, many people have an endless fascination with the IQ scores of famous people. But the truth is that some of the greatest achievements by our species have primarily relied on qualities such as creativity […]
Author: Martha R. Villabona works at Subdirección General de Cooperación Territorial e Innovación Educativa of the Spanish Ministry of Education and Vocational Training, where she coordinates the area of multiple literacies. The seemingly unlimited possibilities of citizen participation in social networks are affected by the polarization of debate, the aggressive style of communication and the […]
Gene found in gecko may have link to melanoma SPINT1, a gene responsible for the skin coloring of Lemon Frost geckos, may play a role in the lizards’ propensity to develop tumors and has also been linked to the development of melanoma in humans, a study in PLOS Genetics suggests. “Studying a gecko is not […]
