Machine learning algorithms will accelerate the production of cardiac prostheses
2023-10-20 20:23
Scientists have proposed using artificial intelligence to develop new prosthetic heart valves. The combination of machine learning models together with mathematical optimization algorithms makes it possible to accelerate the selection of multiple parameters of the prosthesis flaps and obtain a heart valve of an "ideal" configuration several thousand times faster than in the case of classical development bas...
WMO: Global stocktake of water resources needed
2023-10-13 18:43
The hydrological cycle is spinning out of balance as a result of climate change and human activity, according to a new report from the World Meteorological Organization (WMO) that offers an extensive assessment of global water resources.
Destructive droughts and heavy rains are causing major damage, while melting snow and glaciers heighten flood risks and endanger long-term water security, WMO said.

"Our schools are not just about learning, they are about life": the project "Learn to know" changes the attitude of children with cancer to the disease
2023-10-06 18:16
More than 400 thousand Russian children today need long-term treatment. The network of schools "UchiMznay" throughout Russia helps cancer-stricken schoolchildren undergoing treatment in hospitals not to pause in the educational process and changes their attitude to the disease. About the project – in a story from Russia dedicated to the World Teacher's Day, which is celebrated on the fifth of October.

Scientists talked about new ways to combat neurodegenerative diseases
2023-09-29 17:37
Scientists analyzed studies on neurodegenerative diseases such as Alzheimer's, Huntington's and dementia with Levi's corpuscles, and found out what an important role three proteins of the PIDDOSOME complex play in them, triggering the process of programmed cell death. Thus, mutations in two of them — PIDD1 and RAIDD — lead to abnormalities in brain development, and an excess of the third — caspa...
Archaeologists discover world’s oldest wooden structure
2023-09-22 19:39
Half a million years ago, earlier than was previously thought possible, humans were building structures made of wood, according to new research by a team from the University of Liverpool and Aberystwyth University.
The research, published in the journal Nature, reports on the excavation of well-preserved wood at the archaeological site of Kalambo Falls, Zambia, dating back at least 476,000 years and predat...
Long-moustached short-moustaches: a transitional form between mosquitoes and flies was found in the Triassic
2023-09-15 11:38
The order Diptera includes, as the name implies, insects with only one pair of wings. The body structure of diptera can be reduced to two main types: mosquitoes with multi-lobed antennae and flies with three-lobed antennae. This difference was noticed a long time ago: diptera were divided into long-whiskered Nematocera and short-whiskered Brachycera in the first half of the XIX century. But as often happens...
3D-Printed ‘Living Material’ Could Clean Up Contaminated Water
2023-09-08 18:58
Researchers at the University of California San Diego have developed a new type of material that could offer a sustainable and eco-friendly solution to clean pollutants from water.
Dubbed an “engineered living material,” it is a 3D-printed structure made of a seaweed-based polymer combined with bacteria that have been genetically engineered to produce an enzyme that transforms various organic pollutants in...
