Amniotic fluid contains cells, cells shed by the growing fetus and which could be used to build “mini organs” in vitro, as a new study reports . What do we mean by “mini organs”? This so-called organoids are 3D cellular systems that aim to replicate the structure and function of real organs but at a […]

Superconductors can carry large electrical currents without any resistance. One situation where they don’t carry currents without resistance is when there is too much current. By designing microscopic electronic components made from very thin superconductors, researchers can use this effect to create a switch, like a transistor. Nanowire superconducting switching devices (called nanocryotrons, or nTrons […]
Authors: Elissa-Marie Cocquyt, speech therapist and postdoctoral researcher at the University of Groningen & Adrià Rofes, assistant professor of Neurolinguistics at the University of Groningen. The human brain is one of the most wonderful organs. In general, our brain consists of a left and right part, of which the outermost layer is called the ‘cortex’ […]
Spontaneously broken symmetries are at the heart of many phenomena of quantum matter and physics more generally. However, determining the exact symmetries that are broken can be challenging due to imperfections such as strain, in particular when multiple electronic orders are competing. This is exemplified by charge order in some kagome systems, where evidence of […]

Floating offshore wind (FOW) is one of the most rapidly growing forms of green power. As of 2021 though, there were only 113 MW in operation in Europe, although this figure is predicted to triple by the end of 2024, and escalate up to 10 GW by 2030 and 150 GW by 2050. The current […]
Complementary metal–oxide–semiconductor (CMOS) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions. CMOS technology is used for constructing integrated circuit chips, including microprocessors, microcontrollers, memory chips, and other digital logic circuits. After 50 years of continuous transistor size downscaling and […]
The geologists of the International Commission on Stratigraphy’s Subcommission on Quaternary Stratigraphy (SQS) made a substantial decision on March 4, 2024 , by rejecting the proposal to formally acknowledge the beginning of the Anthropocene—a new geological epoch attributing humanity’s emergence as the primary force shaping the Earth’s strata. This proposal, led by the Anthropocene Working […]
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. Parasitism is very common among invertebrates, but much less so among vertebrates. The case of lampreys is well known. They attach to the […]
Tantalum is one of the rarest elements and has multiple stable isotopes. The least abundant tantalum isotope, Ta-180 is found naturally in a long-lived excited state, a feature unique to this isotope. In excited states, a nuclei’s protons or neutrons have higher than normal energy levels. Although energetically possible, the radioactive decay of this excited […]
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 […]
