Whenever an electric current flows a magnetic field is produced; as the orbital motion and the spin of atomic electrons are equivalent to tiny current loops, individual atoms create magnetic fields around them, when their orbital electrons have a net magnetic moment as a result of their angular momentum. The magnetic moment of an atom […]
When you are trying to solve one of the biggest conundrums in cosmology, you should triple check your homework. The puzzle, called the “Hubble Tension,” is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe’s initial conditions and our present understanding […]
Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission. Currently, he is a researcher of the UPV/EHU. He investigates the role of stem cells in physiologic and pathologic conditions. Senescence can be defined as […]
Amphibian feeds its babies milk-like liquid A legless amphibian, called a caecilian, produces a liquid for its babies that provides lipids and sugars, similar to mammalian milk. Siphonops annulatus babies also eat their mother’s skin once a week, and the team discovered the nutritive fluid after wondering how they could be so active and eat […]
Twisted bilayer and multilayer systems represent two-dimensional materials, where atom-thick layers of the same or different materials are superimposed and rotated by an arbitrary twist angle. Twisted bilayer graphene (TBG) represents arguably the most prominent physical system of this kind, the bilayers of transition metal dichalcogenides (TMD) the other. The effect of twisting two periodic […]
When we say that someone is black or white, we may think that he or she belongs to a biological category defined by his or her color. Many people believe that skin pigmentation reflects belonging to a race, “one of the main groups that humans can be divided into according to their physical differences, for […]
Atomic force microscopy, or AFM, is a widely used technique that can quantitatively map material surfaces in three dimensions, but its accuracy is limited by the size of the microscope’s probe. A new AI technique overcomes this limitation and allows microscopes to resolve material features smaller than the probe’s tip. A new deep learning algorithm […]
Acute Myeloid Leukemia (AML) is a hematopoietic neoplasm characterized by the proliferation and accumulation of aberrant immature myeloid progenitor cells. AML is associated with poor clinical outcome and high mortality, with an overall five-year survival rate of less than 15-30%. For AML patients, standard therapies often fail to achieve the complete remission, disease relapse is […]
Why did humans evolve without tails? Though humans’ ape ancestors have tails, we evolved without them due to a single gene mutation, which was pinpointed through researching the genomes of six ape species and 15 monkey species. Scientists are unsure whether becoming tailless was an evolutionary benefit or a chance mutation, but one theory is […]
