NOAA Has Kept Records On Global Warming For Decades. COVID-19 Could Disrupt It All – Colorado Public Radio

Every workday for Scientist Eric Moglia starts the same. He drives to the shipping and receiving department to retrieve packages from far-flung spots like Alaska, Mongolia and Algeria. Inside them is precious information about climate change. But those packages might stop…

Removing the novel coronavirus from the water cycle

(University of California – Riverside) Researchers at UC Riverside and the University of Salerno have called for more research to determine the best ways to keep SARS-CoV-19 out of the water cycle. They also suggest that developed nations should finance water treatment systems in the developing world to help prevent future COVID-19 pandemics.

Using chemistry to unlock the difference between cold- and hot-brew coffee

Cold brew may be the hottest trend in coffee-making, but not much is known about how this process alters the chemical characteristics of the beverage. Now, scientists report that the content of potentially health-promoting antioxidants in coffee brewed without heat can differ significantly from a cup of joe prepared the traditional way, particularly for dark roasts.

This new blood test accurately predicts 50 types of cancer

An international team of scientists may have made a major breakthrough in early cancer detection: a blood test that finds more than 50 types of cancer, including specific locations in the body. They did it with a little help from…

Plant protection: Communication instead of poison

(Karlsruher Institut für Technologie (KIT) ) Increasing drought and heat seriously affect plants. In the Upper Rhine area, for example, climate change results in the development of new plant diseases, an example being Esca, a disease that causes vines to die. Researchers of Karlsruhe Institute of Technology (KIT) and partners have now launched the DialogProTec project that focuses on new approaches to plant protection without herbicides and fungicides. In collaboration with colleagues from Germany, France, and Switzerland, the researchers are conducting research in dialog with winegrowers, farmers, and industry.

The candy-cola soda geyser experiment, at different altitudes

(American Chemical Society) Dropping Mentos® candies into a bottle of soda causes a foamy jet to erupt. Although science fair exhibitors can tell you that this geyser results from rapid degassing of the beverage induced by the candies, the precise means by which bubbles form hasn’t been well characterized. Now, researchers reporting in ACS’ Journal of Chemical Education used experiments in the lab and at various altitudes to probe the mechanism of bubble nucleation.

On Mars or Earth, biohybrid can turn carbon dioxide into new products

Chemists have created a hybrid system of bacteria and nanowires that captures energy from sunlight and transfers it to the bacteria to turn carbon dioxide and water into organic molecules and oxygen. On Earth, such a biohybrid could remove carbon dioxide from the atmosphere. On Mars, it would provide colonists with raw material to manufacture organic compounds ranging from fuels to drugs. The efficiency is greater than the photosynthetic efficiency of most plants.

Tree rings could pin down Thera volcano eruption date

(University of Arizona) Research led by the University of Arizona Laboratory of Tree-Ring Research has anchored a long sequence of tree rings, providing context for the civilizations that existed throughout the Bronze and Iron Ages, including the eruption of Thera.
