More children than ever before live as migrants or refugees, outside their birth countries – UNICEF
2021-08-28 15:01
More girls and boys than ever are on the move, with 35.5 million having lived outside their country of birth in 2020 and an additional 23.3 million displaced internally, according to a new report by the UN Children’s Fund (UNICEF) published on Friday.
The report, Uncertain Pathways, found that over the course of the year, there were almost 15 million new displacements or 41,000 each day, and that boys outn...
Physicists have directly observed the movement of atoms in liquid water molecules
2021-08-27 20:52
For the first time, an international group of experimental physicists from the United States and Sweden directly observed how hydrogen atoms in water molecules pull and push neighboring molecules when they are excited by laser light.
Each water molecule contains one oxygen atom and two hydrogen atoms, and a network of hydrogen bonds between positively charged hydrogen atoms in one molecule and negatively c...
The main structures of dark RNA are described
2021-08-26 17:51
Non-coding RNA in the cell enters some important organelles, regulates protein synthesis, accelerates individual reactions and participates in other biologically important processes. Often, the functioning of non-coding RNAs is ensured by stable interactions of the nucleotides of one or more RNA molecules. A bioinformatician from MIPT and the Institute of Mathematical Problems of Biology of the Russian Acad...
Scientists have found out when the first quadrupeds appeared on Earth
2021-08-25 17:59
American scientists, using mathematical methods of Bayesian modeling, restored the dynamics of the evolution of the first quadrupeds, which descended from fish 400-360 million years ago and gave rise to all vertebrate inhabitants of the land.One of the most important evolutionary events in the history of life on Earth is the transition from fish to quadrupeds — vertebrates with limbs. It happened somewhere ...
The quantum simulator solved a problem that took a week of work of a powerful computing cluster in two hours
2021-08-24 18:46
Scientists from the Moscow Institute of Physics and Technology, MISIS, the Russian Quantum Center, the Bauman Moscow State Technical University, and the Dukhov All-Russian Research Institute of Automation conducted an experiment in which superconducting qubits simulated the transfer of photons in the Bose-Hubbard model. The numerical solution of the model on a classical computer to verify the experimental d...
What inheritance do we leave to our children? A new UNICEF study
2021-08-23 18:49
Almost every child on the planet is more or less exposed to climatic or environmental hazards. Hundreds of millions of children and adolescents may die, be injured or become ill as a result of cyclones, floods, droughts or air pollution.
Today, a report with the climate risk index for children was published for the first time under the auspices of UNICEF, according to which children in the Central African ...
Scientists have received evidence of a cycle of the Earth's magnetic field with a period of 200 million years
2021-08-22 18:12
The results of a new study by the University of Liverpool provide additional evidence for an approximately 200-million-year cycle of the strength of the Earth's magnetic field.
Scientists performed thermal and microwave paleomagnetic analysis of rock samples from ancient lava flows in Eastern Scotland to measure the strength of the geomagnetic field at key time periods in the practical absence of previ...
