Abstract A new species, Echeveria machucae (be. nudesCrassulaceae), is described from specimens collected in El Jacal, municipality of Atenguillo, Jalisco. He is a supposed close relative of E. flammígerafrom which it is differentiated by having larger stems, larger leaves, racemose to occasionally thyrisform inflorescences, longer pedicels, presence of yellow corollas and wider yellow nectarian scales….
Literature reviews provide the building blocks for business research, assisting in theory, evidence-based practice and the advancement of knowledge. Systematic, semi-systematic and integrative reviews have advantages and disadvantages, since determining the type of review will depend on the purpose of the research. In any case, conducting a good literature review involves careful planning, transparent methodology,…
Government teams across Australia are turning weeks of manual data work into hours of actionable knowledge Dimensions brings together grants, research, collaborators and results into a single, trusted view, giving agencies the tools to: Track program results faster Eliminate siled data workflows Support evidence-based policy Report clearly and confidently Whether informing national priorities, advising ministers…
Why did people think cannibalism was good for their health? The answer offers a glimpse into the quirkiest corners of European history, at a time when Europeans were obsessed with Egyptian mummies. Driven first by the belief that crushed and dyed human remains could cure everything from bubonic plague to headaches, and then by Victorian…
I added some new Halloween science experiments to our collection this year, so I thought I’d include them in one big roundup with lots of great ideas from other bloggers too. Here at Science Sparks, we love Making science spooky! We’ve got fizzy witch potions, spooky chia seed slime, a spooky noise maker, a pumpkin…

DLESyM 模型在模拟热带气旋和印度夏季季风方面优于 CMIP6 模型。它至少与CMIP6 1000年模拟结束时（3016 年）生成的东北风暴的结构与 2018 年观测到的东北风暴非常相似. 然而，新模型和CMIP6此外，对于中期预报（即未来 15天左右的预报），DLESyM DLESyM DLESyM compliant, CMIP6 compliant (AGU Advances, https://doi.org/10.1029/2025AV0017062025) —科学撰稿人Madeline Reinsel This translation was done by wiley. 本文翻译由wiley提供。 Read this article on WeChat. 在微信上阅读本文.

Now, geological analysis reveals that the swarm…
Credit: Mi. When a Ukrainian soldier receives shrapnel from the explosion of a mine or some ammunition launched from a drone, survival depends on a few seconds. Those seconds now belong to artificial intelligence. In the midst of the war with Russia, Ukraine has become an unexpected testing field for AI Battlefield Medicine. A new…
Eric World essay One billion here, one billion there, you will soon be talking about real money. Snowy Hydro 2.0 indicates another cost explosion with a price of 12 billion dollars that is now considered unattainable The pumping hydroelectric project in the Kosciuszko National Park is complete at 67%, but the cost increases in the…
“I came today to put a face to science and what these cuts mean, and I also wanted to change the script to be called ‘scammer’ to be called a patriot. I think scientists serve their country using the skills they have.” –Dr Jennifer Moraash, June 2025 days of participating action Scientists serve communities through…
