Scientists discover a new complex europium hydride
2020-12-21 18:26
A team of researchers from Russia, the United States and China led by Skoltech Professor Artem R. Oganov have discovered an unexpected very complex europium hydride, Eu8H46. The paper detailing the discovery has been published in The Journal of Physical Chemistry letters.
Superhydrides of rare-earth metals are interesting compounds that form under pressure: some exhibit high-temperature superconductivity t...
The oldest samples of mammalian wool were found
2020-11-23 18:34
RIA of news. Spanish paleontologists reported finding two unique amber specimens in the province of Teruel. In one of them, scientists found dinosaur feathers, and in the other — the world's oldest mammalian hair.
The age of the finds is 105 and 110 million years, which corresponds to the early Cretaceous period. Cretaceous amber has been found in the province of Teruel before, but this is the first ti...
Beat the record temperature for superconductivity
2020-11-05 20:32
Compressing simple molecular solids with hydrogen at extremely high pressures, University of Rochester engineers and physicists have, for the first time, created material that is superconducting at room temperature.
Featured as the cover story in the journal Nature, the work was conducted by the lab of Ranga Dias, an assistant professor of physics and mechanical engineering.
Dias says developing materials...
Denisovan DNA found in sediments of Baishiya Karst Cave on Tibetan Plateau
2020-11-01 13:48
One year after the publication of research on the Xiahe mandible, the first Denisovan fossil found outside of Denisova Cave, the same research team has now reported their findings of Denisovan DNA from sediments of the Baishiya Karst Cave (BKC) on the Tibetan Plateau where the Xiahe mandible was found. The study was published in Science on Oct. 29.
The research team was led by Prof. CHEN Fahu from the Inst...
The ancient Mayans used zeolite and quartz to filter drinking water
2020-10-26 18:11
Tikal-an ancient city in what is now Northern Guatemala, is one of the largest political, economic and military centers of the pre-Columbian Mayan civilization. It was inhabited from the 6th century BC to the 10th century ad, and during its heyday the population was up to 90,000.A large reservoir, called reservoir Mariental, was an important source of drinking water for the city. A team of archaeologists fr...
Real-time tracking of serotonin and dopamine opens up a new perspective on the brain
2020-10-13 20:12
Dopamine and serotonin are brain chemicals that affect a range of neurological disorders, including Parkinson's disease and depression, so understanding how they work could be key to developing more effective treatments for these conditions.
The new tool offers an unprecedented look at these neurotransmitters in action, allowing scientists to track their activity in real time for the first time.
Both ...
Scientists have developed a technology for printing personalized neuroprostheses on a 3D bioprinter
2020-08-24 17:34
Researchers from Saint Petersburg state University have developed a 3D printing technology for soft neuroprostheses called NeuroPrint, which in the future can help literally put a person on their feet after a spinal cord injury. The new development has already shown its effectiveness in studies on mammals and fish Danio-rerio. The results are published in the prestigious scientific journal Nature Biomedical...
