Archaeologists have described the stone tools of the ancient inhabitants of the modern Krasnodar Territory
2024-07-05 14:27 Archaeologists have described five types of pointed stone tools, which 80-40 thousand years ago were used by Neanderthals who inhabited the Mezmai cave in the south of the Krasnodar Territory (in the Northwestern Caucasus). The authors conducted a statistical comparative analysis of these groups, which showed significant differences between them. The tools differ not only in proportions, but also in the deg...
1.8 billion people on the planet are at risk of illness due to insufficient physical activity
2024-06-28 16:58 Almost a third (31 percent) of the adult population worldwide – approximately 1.8 billion people – did not comply with recommended physical activity standards in 2022. Experts from the World Health Organization (WHO) came to this conclusion. The results of their study were published in The Lancet Global Health journal. According to WHO, the prevalence of insufficient physical activity among adults increased...
Full-scale measurements of atmospheric ozone's own radiation with high accuracy

On World Oceans Day, the UN urges humanity to "reach new depths"
2024-06-07 18:39 On June eighth, the United Nations celebrates World Oceans Day, designed to draw attention to the need to protect the oceans. Paradoxically, humanity, whose survival depends entirely on the well-being of ocean ecosystems, is today the main and worst enemy of the ocean, mindlessly destroying its resources. Man and the ocean have lived in peace for many millennia. The lack of technology did not allow people t...
Scientists have compiled a "route map" of lymphocytes
2024-05-31 19:08 Scientists have determined how lymphocytes — immune cells — move between organs when they are artificially injected into the blood, for example, in the treatment of cancer. Modeling has shown that such cells, moving with blood and lymph, do not affect the circulation of natural T-lymphocytes, accumulating mainly in the spleen, liver and lymph nodes. The data obtained will help to calculate the optimal numbe...

Curiosity promotes biodiversity
2024-05-03 20:08 Exploratory behavior is one of the fundamental personality traits of animals – and these traits influence their probability of survival, among other things. For example, curious individuals can inhabit different areas in their habitats compared to more cautious conspecifics. At the same time, however, they expose themselves to a greater risk of being discovered and eaten. The cichlids of Africa’s Lake Tang...
Stone Age people were able to use the surrounding landscape for their own purposes
2024-04-26 17:02 For the first time, MSU scientists and colleagues described in detail the terrain at the time of human habitation at the Byki parking lots in the Kursk region. So, using geophysical methods, the authors of the study found out that in the Late Stone Age era — 21-18 thousand years ago — the studied area was covered with elevated sand dunes alternating with rounded depressions. The ancient people chose the hil...
World Creativity and Innovation Day
2024-04-19 09:12 Creativity and innovation in problem-solving There may be no universal understanding of creativity.

Scientists have created a device for the operation of "quantum" neural networks
2024-03-08 20:09 Russian scientists have proposed a superconducting logic cell, which can be both an integral part of a quantum computer and a component of a neural network — an artificial neuron. In the future, it will be used to design elements for neuromorphic information processing in quantum processors — in fact, "quantum" neural networks. The results of the study, supported by a grant from the Presidential Program of ...
Air Pollution Hides Increases in Rainfall
2024-03-01 20:44 We know that greenhouse gas emissions like carbon dioxide should increase rainfall. The emissions heat the atmosphere, causing a one-two punch: warmer oceans make it easier for water to evaporate, and warmer air can hold more water vapor, meaning more moisture is available to fall as rain. But for much of the 20th century, that increase in precipitation didn’t clearly show up in the data.A new study led by ...
New compounds for the treatment of metastatic melanoma have been created at St. Petersburg Polytechnic University
2024-02-23 19:13 SPbPU scientists have developed new antitumor compounds based on thienopyrimidines to increase the effectiveness of cancer therapy. The studies were conducted on a model of metastatic melanoma in animals. The results showed that the compounds significantly inhibit the formation of metastatic nodes.

PNRPU scientist has developed a way to regulate a robot for the production of sound-absorbing structures
2024-02-02 20:11 Noise abatement in aviation ranks second in importance after flight safety. 140 dB sound intensity (airplane taking off) it can cause concussion in humans, and at 160 dB, ruptures of the eardrum are possible. To reduce noise in an aircraft, sound-absorbing structures with numerous holes in the material are used. In aircraft engine building, a robot is involved in shaping these holes, which processes them wi...

Nanozymes will help diagnose hormones and blood diseases
2024-01-05 20:23 Scientists have developed special nanoparticles — nanosimes. They are used in molecular biological analyses as a label - they can be used to tint colorless substrates (antibodies, antigens, hormones) during diagnosis. Unlike natural analogues, nanosimes have high signal stability and are also relatively cheap. Scientists note that the use of nanosimes in the future will help reduce the prices of various med...
