A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, provides the first direct evidence of the imprint left by what may be the universe’s most powerful magnetic fields on “deconfined” nuclear matter . The evidence comes from […]
Dinosaur species may have crossed sea to find Africa Fossils in Morocco reveal a previously unknown duckbill dinosaur species, Minqaria bata, which is anatomically similar enough to duckbill species found in Europe to suggest that the pony-size creatures swam or floated across the Tethys Sea and diversified quickly into at least three species in North […]
Nuclear power is considered one of the ways to reduce dependence on fossil fuels, but how to deal with nuclear waste products is among the issues surrounding it. Radioactive waste products can be turned into more stable elements, but this process is not yet viable at scale. New research led by physicists from the University […]
Stone Age travel story emerges from DNA of “Vittrup Man” Advanced analysis of DNA, teeth and bones of the bog-preserved body of Denmark’s “Vittrup Man” has revealed the individual’s history as well as possible movements and connections between Stone Age cultures. Vittrup Man’s genetics suggest an origin on the Scandinavian Peninsula, where he likely grew […]
In most materials, heat prefers to scatter. If left alone, a hotspot will gradually fade as it warms its surroundings. But in rare states of matter, heat can behave as a wave, moving back and forth somewhat like a sound wave that bounces from one end of a room to the other. In fact, this […]
Iceland volcano’s magma hits unprecedented speed Magma underneath Iceland’s Reykjanes peninsula flows at an “ultra-rapid” 7,400 cubic meters per second, and the same magma river likely caused Thursday’s eruption. The unprecedented speed indicates the role of not only pressure but also tectonic stress and ground fracturing in a volcano’s likelihood to erupt, says Sigrun Hreinsdottir […]
Neolithic burial site poses mystery of missing bones Missing skulls and thigh bones have sparked questions about burial practices in early Neolithic Sweden, where archaeologists have revisited one of Scandinavia’s oldest stone burial chambers from around 3500 BCE. The site, called a dolmen, holds the remains of 12 or more people of varying ages, and […]
Collisions of high energy particles produce “jets” – quarks, antiquarks, or gluons moving through the quantum vacuum. Due to the confinement property of strong interactions, quarks are never directly detected but instead fragment into many secondary particles. Scientists have long expected that as jets propagate through the confining quantum vacuum, they will modify that vacuum […]
Invasive ants disrupt hunting by lions in Kenya Invasive ants have disrupted interspecies patterns in Kenya, triggering a drop in the number of zebras killed by lions. As big-headed ants spread in East Africa, they kill native acacia ants, which leads to the destruction of whistling-thorn trees that lions use as cover when hunting. Full […]
Researchers link reaction inside moon to unique rocks A reaction between magma and solids that occurred beneath the lunar surface 3.5 billion years ago may have created unique rocks now sitting on the moon. The rocks contain high levels of titanium, say researchers, who combined high-temperature molten-rock laboratory experiments with a close review of basalts […]
