Fish communicate to stay close to each other Fish use calls to stick together as a group, a new study suggests. Researchers played recordings of bigeye vocalizations for captive wild bigeyes, and noted that their own vocalizations increased and they swam more closely together than they did when no recordings were played. “This study means […]

Ancient grooves may be evidence of dinosaur mating ritual Four sites found in Colorado exhibit fossilized grooves that may have been made by dinosaurs doing a bird-like mating dance more than 100 million years ago. Scientists say the gouges could have been made by theropods performing a mating ritual common to modern birds. The Washington […]

Robots will be ubiquitous in the near future, few people would argue against that, with some authors even talking of a “ Cambrian Explosion of robotics ” . This bigger presence of robots in our daily life has accelerated the subfield of roboethics , which is trying to establish how we must design, use and […]

Mystery of disappearing electrons may be solved A band of invisible meteor dust drifting to Earth may be behind the disappearance of electrons in the high atmosphere that’s had scientists baffled since the 1960s Electrons are produced high above Earth when the sun’s ultraviolet rays interact with atmospheric nitric oxide, but a big drop has […]

As you can imagine from the reading of the previous entries, it was by no means an easy task to transform skepticism into a weapon against religious belief. This does not entail that criticisms of religion tout court had failed to exist before, say, the late Modern Age. Not to mention again our adorable Greeks […]

How information might be retrieved from a black hole There may be a way to retrieve a bit of information from inside a black hole. A team of physicists from the California Institute of Technology theorizes that the information can be gleaned by using Hawking radiation exiting the black hole and quantum teleportation. Science Crows […]

Plesiosaurs swam ancient oceans like penguins Plesiosaurs swam much like penguins do, using their front flippers to propel themselves and their back ones to control their direction. How the ancient marine reptiles moved through water was unclear since its fossils were discovered about 200 years ago. Researchers developed a computer model based on a nearly […]

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 […]

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 […]

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’ […]
