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
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
A team of researchers at CSIRO has decoded the genome of the spotted handfish (Brachionichthys hirsutus), a critically endangered species of marine fish endemic to Tasmania.

This unusual fish lives only in the
Gliese 229B was the first known brown dwarf, discovered in 1995. In new research, astronomers observed Gliese 229 B with the GRAVITY interferometer and, separately, the CRIRES+ spectrograph at ESO’s Very Large Telescope. Both sets of observations independently resolved Gliese 229B into two components, Gliese 229 Ba and Bb. They orbit each other every 12.1 days with a semimajor axis of
