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 […]

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 […]

More than a hundred years have passed since the German physicist Alois Alzheimer associated the traits of dementia of one of her patients with morphological changes in her brain after her death. While we know a great deal about what today is known as Alzheimer’s disease, we still need to answer two fundamental questions: what […]

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 […]

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 […]

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 […]
