Southwest Research Institute (SwRI) scientists observed the first close-ups of a source of energetic particles expelled from the sun, viewing them from just half an astronomical unit (AU), or about 46.5 million miles. The high-resolution images of the solar event were provided by ESA's Solar Orbiter, a sun-observing satellite launched in 2020.
Things do not always go as one wants in reality. This is especially true in the world of light. However, a research team at POSTECH has successfully controlled "trions," a breakthrough toward developing what could ultimately be revolutionary optical communication technology.
The Egyptian cotton leafworm (Spodoptera littoralis) is a pest species in France. It is found throughout the Mediterranean Basin as well as in Africa and the Middle East. Moth larvae are extremely polyphagous and cause damage to diverse crop species (e.g., corn, legumes, cotton, tomatoes, peppers).
Environmental DNA research has aided conservation, but scientists say its ability to glean information about human populations and individuals poses dangers.
A research team, composed of climatologists and an astronomer, have used an improved computer model to reproduce the cycle of ice ages (glacial periods) 1.6 to 1.2 million years ago. The results show that the glacial cycle was driven primarily by astronomical forces in quite a different way than it works in the modern age. These results will help us to better understand the past, present, and future of ice sheets and the Earth's climate.
Anthropogenic factors on the West African coast are contributing more than global climate change to the rapid increase in vulnerability and flood risks in the region. This was demonstrated by an interdisciplinary IRD team, in collaboration with West African experts and the CNES, in a pilot quantification study published in Communications Earth & Environment.
Quick assessment of trace blood components in untreated blood samples is possible with fluorescence tests but, in practice, blood's strong autofluorescence interferes with the analysis. In the journal Angewandte Chemie International Edition, a research team has now introduced a novel fluorescence probe that quenches this autofluorescence and precisely quantifies traces of hydrogen sulfide, which is an important signal molecule.
Carbon dioxide (CO2) is a major greenhouse gas emitted through various types of human activities. In an effort to decrease humanity's carbon footprint, scientists and policymakers across the globe are continuously trying to explore new methods for reducing atmospheric CO2 emissions and converting them into useful forms. In this regard, the electrochemical method of reducing CO2 to other carbonaceous forms like carbon monoxide, alcohols and hydrocarbon has gained considerable attention.
Rivers, lakes and oceans worldwide are home to trillions of pieces of plastic pollution that are smaller than five millimeters in length, known as microplastics, and their size allows them to easily enter humans and animals. Some can adsorb and transport other harmful toxicants that pollute waterways, including certain types of a more recently discovered set of toxic "forever chemicals" called per- and polyfluoroalkyl substances, or PFAS.
