💧Did you know that the single-year severe drought of 2002 was not unprecedented in comparison with multi-year persistent droughts? 🌳A tree-ring-based evaluation of water supply variability for the #SaltVerde River Basin by David Meko and Katherine Hirschboeck revealed that 28 other drought periods between 1814 and 2006 were continuously severe.

🪨Did you know Earth’s rocky outer layer can thin without cracking at the surface? A study by Gilby Jepson and co-researchers shows that in southern #Arizona, this rocky layer shrank from about 65 km to 28 km over millions of years, much of it happening quietly deep underground before major cracks formed. These hidden movements helped shape the landscape we see today. See their dataset & article at https://doi.org/10.25422/azu.data.17227538 & https://doi.org/10.1029/2021JB02385.

🌋 Did you know lava flows are more complex than just two types, the classic ʻaʻā and pāhoehoe? A detailed study of Iceland’s massive #Holuhraun eruption by Joana R.C. Voigt, Christopher W. Hamilton and co-researchers shows that most lava is between classic types, and surface texture alone doesn’t tell the full story.

🌧️Did you know the timing of #rain could matter more than the total amount? Research by Fangyue Zhang, Joel Biederman, Nathan Pierce, Daniel Potts, Charles Devine, Yanbin Hao & William Smith indicates that fewer, larger storms can delay peak plant productivity in semi-arid grasslands by weeks, reshaping ecosystems and influencing land management decisions🌱.

🧬🩹Did you know a molecule called Sonic Hedgehog (#Shh) helps heal stomach wounds like ulcers? Jayati Chakrabarti, Martha Dua-Awereh, Michael Schumacher, Amy C. Engevik and Yana Zavros found that Shh signals immune cells to move to injured stomach tissue, and without this signal, healing slows dramatically.

🌊Did you know over half the world’s rivers run dry for part of the year? A study by Brian A. Gill, Anthony Sanabria, Miranda Gonzales, Stephanie M. Carlson & Michael T. Bogan reveals how drying and distance from permanent streams reshape which aquatic species can survive. With more drying ahead, many species risk disappearing.
