Jan 26, 2023... January 23, 2023—When looking at the Earth from space, its hemispheres – northern and southern – appear equally bright. This is particularly unexpected because the Southern Hemisphere is mostly covered with dark oceans, whereas the Northern Hemisphere has a vast land area that is much brighter than these oceans. For years, the brightness symmetry between hemispheres remained a mystery. In a new study, published in the Proceedings of the National Academy of Sciences (PNAS), Weizmann Institute of Science researchers and their collaborators reveal a strong correlation between storm intensity, cloudiness and the solar energy reflection rate in each hemisphere. They offer a solution to the mystery, alongside an assessment of how climate change might alter the reflection rate in the future.
Feb 03, 2023... REHOVOT, ISRAEL— February 3, 2023 Arthropods crawl and buzz around us in the wild and on farmlands, on the street and at home, under our floors and in our plumbing systems, even in our food and on our bodies. But while we often are inconvenienced by this group of invertebrates – which comprises more than a million species, including all insects – their absence would be catastrophic: Arthropods are ecosystem engineers that pollinate our crops, turn over agricultural soils and sustain an enormous diversity of predators, from warblers to wolverines, that feed on them directly or indirectly.
