CMS collaboration measures speed of sound in quark-gluon plasma with unprecedented precision

Neutron stars in the universe, ultracold atomic gases in the laboratory, and the quark–gluon plasma created in collisions of atomic nuclei at the Large Hadron Collider (LHC): they may seem totally unrelated but, surprisingly enough, they have something in common. They are all a fluid-like state of matter made up of strongly interacting particles. Insights … Read more

DNA analysis shows violent replacement of scandinavian hunter-gatherers by farmers

Following the arrival of the first farmers in Scandinavia 5,900 years ago, the hunter-gatherer population was wiped out within a few generations, according to a new study from Lund University in Sweden, among others. The results, which are contrary to prevailing opinion, are based on DNA analysis of skeletons and teeth found in what is … Read more

Scientists combine 3D printing and soaking process to mimic bone microstructure

Scientists have combined laser 3D printing technology and an alternate soaking process to construct complex 3D structures that mimic bone microstructure. This is the first demonstration of this fabrication method, and it will lead to the development of 3D cell culture systems that can support bone grafts or create artificial bone marrow. Their research is … Read more

Stone age hunters built 1km wall in Baltic Sea 11,000 years ago

In autumn 2021, geologists discovered an unusual row of stones, almost 1 km long, at the bottom of Mecklenburg Bight. The site is located around 10 kilometers off Rerik at a 21-meter water depth. The approximately 1,500 stones are aligned so regularly that a natural origin seems unlikely. A team of researchers from different disciplines … Read more

New study identifies oldest bead in Americas at 12,940 years old

University of Wyoming archaeology Professor Todd Surovell and his team of collaborators have discovered a tube-shaped bead made of bone that is about 12,940 years old. The bead, found at the La Prele Mammoth site in Converse County, is the oldest known bead in the Americas. Surovell’s research is published in Scientific Reports; the paper … Read more

Hubble reveals spectacular star cluster formation in interacting galaxies

When spectacular cosmic events such as galaxy collisions occur, it sets off a reaction to form new stars, and possibly new planets that otherwise would not have formed. The gravitational pull that forces the collisions between these galaxies creates tidal tails—the long thin region of stars and interstellar gas. The Hubble Space Telescope’s vision is … Read more

Roman archaeologists unearth first concrete evidence of black henbane use

A team of archaeologists led by Dr. Maaike Groot from Freie Universität Berlin has provided the first firm evidence that the Romans deliberately collected and used the poisonous seeds of the black henbane plant. The team analyzed seeds found in a hollowed bone discovered at the Roman-period settlement of Houten-Castellum in the Netherlands and compared … Read more

World’s richest lower ordovician fossil site reveals ancient climate refuge in France

Paleontology enthusiasts have unearthed one of the world’s richest and most diverse fossil sites from the Lower Ordovician period (around 470 million years ago). Located in Montagne Noire, in the Hérault department of France, this deposit of over 400 fossils is distinguished by an exceptionally well-preserved fauna. In addition to shelly components, it contains extremely … Read more

Scientists seek planets with “CO runaway” for life’s origins

The search for habitable exoplanets involves looking for planets with similar conditions to the Earth, such as liquid water, a suitable temperature range and atmospheric conditions. One crucial factor is the planet’s position in the habitable zone, the region around a star where liquid water could potentially exist on the planet’s surface. NASA’s Kepler telescope, … Read more

Taming Jekyll-and-Hyde material for miniaturized electronics
