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 […]
A nanoantenna with balanced electric and magnetic dipole moments exhibits a directive radiation pattern with zero backscattering. This is known as the first Kerker condition after Kerker, Wang, and Giles, who predicted in 1983 that, under plane wave illumination, magnetic spheres with equal relative permittivity and permeability radiate no light in the backscattering direction. They […]
Consider the statements below. What do they describe? A trip on psychedelics? A dream? I felt I could reach through the screen to get to another place. Lasers became entire fans of light sweeping around, and then it felt as if the screen began to expand. I saw old stone buildings … like a castle […]
Spaceflight is known to affect human physiology, but the molecular mechanisms driving these changes to our bodies in space, like for instance, the loss of muscular mass, are yet unknown. A recent study in the journal Cell used a multi-omics approach to try and examine these mechanisms. The researchers employed data from NASA’s GeneLab and […]
Coelacanth scales reveal 100-year lifespan Coelacanths, bizarre fish that reside in the deepest ocean depths, can live as long as 100 years, aren’t even mature until they reach about 45 and remain pregnant for as long as five years. Researchers used polarized light to examine the scales of about 30 different coelacanth specimens, finding rings […]
