Whether in flood early-warning systems or in agriculture - rainfall measurements are of great importance. However, there is a lack of accurate data for many regions in the world due to the fact that comprehensive measurements have so far been too expensive. This could change with a new method that has just passed its practical test. Researchers at KIT (Karlsruhe Institute of Technology) and the University of Augsburg have succeeded in utilizing the commercial microwave link network (CML) operated by mobile network providers for Germany-wide rainfall measurements.
Sophia Antipolis, 3 August 2020: Women in their 30s and 40s with a common condition affecting how the ovaries work are more likely to get heart disease. That's the finding of a study published today in the European Journal of Preventive Cardiology, a journal of the European Society of Cardiology (ESC).1
"Polycystic ovary syndrome isn't a life sentence - there are many ways to stay heart healthy," said study author Dr. Clare Oliver-Williams of the University of Cambridge, UK. "Small changes add up, like eating more fruits and vegetables and doing more exercise."
Nobody can shoot a pistol bullet through a banana in such a way that the skin is perforated but the banana remains intact. However, on the level of individual atomic layers, such a feat has now been achieved - a nano-structuring method has been developed at TU Wien (Vienna), with which certain layers of material can be perforated extremely precisely and others left completely untouched, even though the projectile penetrates all layers.
Parasites have a public relations problem.
Unlike the many charismatic mammals, fishes and birds that receive our attention (and our conservation dollars), parasites are thought of as something to eradicate -- and certainly not something to protect.
Supported bimetallic catalysts are an important class of catalysts in heterogeneous catalysis. They can be applied in various fields, such as electrocatalysis, biomass conversion, and hydrogen production.
However, traditional impregnation and immobilization methods for synthesizing supported bimetallic nanoparticles (BNPs) are often uncontrollable, thus creating BNPs with non-uniform particle size, low alloy degree and inhomogeneous distribution on the supports. The result is poor catalytic performance and low metal utilization.
Texas researchers from the University of Houston, Baylor University and Texas A&M University have discovered evidence for why the earth cooled dramatically 13,000 years ago, dropping temperatures by about 3 degrees Centigrade.
The evidence is buried in a Central Texas cave, where horizons of sediment have preserved unique geochemical signatures from ancient volcanic eruptions -- signatures previously mistaken for extraterrestrial impacts, researchers say.
The resolution to this case of mistaken identity recently was reported in the journal Science Advances.
New guidelines published by the Association of Anaesthetists in the journal Anaesthesia, to coincide with the start of World Breast Feeding Week (1-7 August) say that breastfeeding is safe after the mother has had anaesthesia, as soon as she is alert and able to feed.
Solid acids are amongst the most essential heterogeneous catalysts, which have the potential to replace environmentally harmful liquid acids, in some of the most important processes, such as hydrocarbon cracking, alkylation, as well as plastic waste degradation and carbon dioxide to fuel conversion.
Sea surface temperatures in the tropics have a major influence on the climate in the tropics and the adjacent continents. For example, they determine the position of the Intertropical Convergence Zone and the beginning and strength of the West African monsoon. Therefore, it is important to understand the variability of sea surface temperatures for climate predictions. Until now, the seasonal cycle of sea surface temperature in the tropical North Atlantic could not be sufficiently explained.
A global meta-analysis led by UNSW scientists shows tiny organisms that cover desert soils - so-called biocrusts - are critically important for supporting the world's shrinking water supplies.
Biocrusts are a rich assortment of mosses, lichens, cyanobacteria, and microscopic organisms such as bacteria and fungi that live on the surface of dryland soils. Drylands, collectively, are the world's largest biome.
Scientists have long known the earth cooled dramatically about 13,000 years ago, dropping temperatures by about 3 degrees Centigrade. There are several theories about the cause. The leading explanation has been a so-called extraterrestrial event, a massive object slamming into earth from space or bursting in the atmosphere.
When NASA's Aqua satellite passed over the North Atlantic Ocean, it gathered water vapor data on Isaias, while NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image that showed a more organized tropical cyclone.

A material composed of two one-atom-thick layers of carbon has grabbed the attention of physicists worldwide for its intriguing -- and potentially exploitable -- conductive properties.
We are changing the Earth system at a unprecedented speed without knowing the consequences in detail. Increasingly detailed, physics-based models are improving steadily, but an in-depth understanding of the persisting uncertainties is still lacking. The two main challenges have been to obtain the neccesary amount of detail in the models and to accurately predict how anthropogenic carbon dioxide disturbs the climate's intrinsic, natural variability.
A team of scientists led by Nagoya University in Japan has detected a highly unusual atomic configuration in a tungsten-based material. Until now, the atomic configuration had only been seen in trihydrogen, an ion that exists in between star systems in space. The findings, published in the journal Nature Communications, suggest further studies could reveal compounds with interesting electronic properties.
