I consider an offer for a gym membership and decide to accept it after being overconfident that I will use it regularly, but in the end I will not. In other words, I overvalue the offered contract. The opposite is also possible, for instance, I may undervalue car insurance because I underestimate the likelihood of […]

One of the first recognized successes of the early quantum theory arose, not from the study of radiation, but from the theory of solids. Once again in the physics of the first half of the 20th century Albert Einstein was at the forefront; but this time the story is seldom told. After presenting the hypothesis […]

Slime mold is an informal name given to several kinds of unrelated eukaryotic organisms that can live freely as single cells but when food is in short supply, many of these unicellular organisms will congregate to form multicellular structures that move together as a single body. Thus, the aggregation and joint movement require the coordination […]

M ethodological developments in medical imaging, computer sciences and rapid prototyping technologies offer new possibilities for research and formation in anthropology, archaeology and curation procedures but also for the benefit of the cultural heritage. To conduct their studies on rare fossil specimens, anthropologists and archaeologists have to deal with two challenges. First, the specimens of […]

Unfossilized dinosaur blood vessels discovered Blood vessels from an 80 million-year-old duck-billed dinosaur never fossilized and still hold tissue. The vessels are from the leg bone of a Brachylophosaurus canadensis found in Montana. To determine that the vessels were truly organic matter from the dinosaur and not bacteria, scientists used high-resolution mass spectroscopy and detected […]

What more can be learnt from the chemistry of noble gases? Noble gases, the members of group 18 of the periodic table of elements (in previous terminology – group VIII) are known as monoatomic gases. The latter property is the result of their very low chemical reactivity thus, they do not form bonds between themselves […]

We finished our last article saying that it is one thing to accept this newly stated connection between electric and magnetic fields; but it is a little bit harder, and more interesting, to understand the physical necessity for such a connection. We will try to explain this necessity now avoiding the use of mathematics, step […]

I still remember the order and control exhibited by the chemistry of life that they explained to me in the early years of college. For me, the regulation of gene expression was the supreme paradigm of organization. The promoters, those regulatory sequences preceding genes, were unmistakable ports where plenty of proteins (transcription factors and polymerases) […]

1 Introduction Evolutionary linguistics encompasses the origins of language, the change within and across different languages, and the acquisition of language and languages by children and adults (Gong, Shuai, & Zhang, 2014). We shall start framing this voyage by looking back two centuries. Then, some theories of language origins seem to have displayed considerable ‘imagination’ […]

Universe isn’t a hologram, experiment determines A controversial experiment at the Fermi National Accelerator Laboratory has found no evidence supporting the theory that the universe is a giant hologram. The Holometer searched for a kind of holographic noise using interferometers, but nothing has been detected. Science Sonic tractor beam developed A tractor beam that lifts […]
