Paleontologists have described three new enantiornithine birds from the Cretaceous Hell Creek Formation, two of which represent new avisaurid species. These birds lived alongside dinosaurs 68 million years ago and their powerful feet bones suggest they could have captured and carried off prey.

In a study led by the Sapienza University of Rome, caffeine intake was positively correlated with the percentage of circulating endothelial progenitor cells in lupus patients. Orefice et al. studied the role of caffeine intake on endothelial function in lupus patients by assessing its effect on circulating endothelial progenitor cells. Image credit: Sci.News.

The island of Sicily is considered to be among the first occupied by humans in the European Upper Paleolithic. Studies to understand early occupation of the island are mostly concentrated on the northern shores. An international team of archaeologists led by Washington University in St. Louis has now searched for the human occupation traces in
Home Hydrogen Statera Energy plans utility-scale green hydrogen project in UK October 10, 2024, by Aida Čučuk UK’s Statera Energy has submitted plans for a utility-scale green hydrogen project to be built in Aberdeenshire, Scotland. The project, named Kintore Hydrogen, will help balance a renewables-led power system by using surplus renewable energy to produce green
A group of talented students from Bahria University has developed an innovative device called “Hydrogen” to help combat Pakistan’s water scarcity. This unique machine is designed to extract water directly from the air, providing a practical and affordable solution to the country’s water shortage problems. The device is highly efficient, capable of converting 60% of
El Laco in Chile is an iron-rich volcano complex and also a source of rare earth elements. (Image credit: Daniel P. Gauer via Wikimedia Commons, CC BY 2.0) Volcanoes that are rich in iron might be prime locations to find high concentrations of rare earth elements . Recent lab experiments have demonstrated that when iron-rich magmas
A team of biologists in Israel has grown an extinct — or at least extirpated — tree species of the myrrh genus Commiphora from an ancient seed found in the northern Judean Desert in the 1980s. Morphological features of Sheba at different ages: (a) ancient seed prior to planting; (b) developing seed at 5 weeks
Carbonate minerals are of particular interest in paleoenvironmental research as they are an integral part of the carbon and water cycles, both of which are relevant to habitability. In new research, planetary scientists focused on carbon and oxygen isotope measurements of carbonate minerals detected by NASA’s Curiosity rover within the Gale crater on Mars. An
