Conditions improved in south-central and northern areas of Kansas this week, while both extreme and severe drought expanded slightly in parts of western Kansas.
The state’s vacillating drought conditions over the past few weeks have affected some winter wheat crops. This week’s USDA Crop Progress report rated Kansas’ winter wheat condition at 11% very poor, 21% poor, 36% fair, 29% good and 3% excellent.
French chemist Antoine Lavoisier died #OTD in 1794.
He is best known for his development of the law of conservation of mass, which states that mass is neither created nor destroyed in chemical reactions. This principle helped to debunk the phlogiston theory, which was a prevailing theory at the time that suggested substances released a material called "phlogiston" when they burned. He also made significant contributions in understanding respiration as a form of combustion.
"...menstruation has been understudied for decades, creating a knowledge vacuum in which patients with pain or heavy bleeding wait years for a diagnosis. In recent years, however, more scientists have begun to study the process and menstrual fluid — research that could uncover crucial information about human health that’s been unjustly ignored."
Es gibt laut Youtube erst 1300 Zugriffe auf das Video, in dem @rahmstorf die Wahrscheinlichkeit des Zusammenbruchs des Golfstroms (genauer: der AMOC) bespricht.
Lasst uns das ändern.
Das Video ist verständlich und liefert tiefgehendes Verständnis. Es ist die Zeit wert.
British scientist Rosalind Franklin died #OTD in 1956.
Her most famous contribution to science came from her X-ray diffraction images of DNA, particularly Photo 51, which provided crucial evidence for the double helix structure of DNA. Her photo was shared without her knowledge with J. Watson & F. Crick, who used it as a basis for their model of DNA's structure. Their work overshadowed her contribution, & she was not fully recognized for her role until after her death.

This is how technology changes our view of reality.
The enormous LSST camera (the eye of the Rubin Observatory) will will soon start scanning the entire visible universe every 3-4 days. It will create the grandest movies ever made, watching for anything moving, flickering , appearing, or vanishing in deep space.
Random Thought: I wonder when modern neurotransmitters evolved. The neurotransmitters we know and love (serotonin, gaba, glutamate, dopamine, epinephrine/norepinephrine, histamine ETC) are in use by mammals and reptiles, so i'm guessing like 10-20 million years ago. #science#neuroscience
