In a new study, astronomers compared high-resolution images of Uranus from the NASA/ESA Hubble Space Telescope to the more-distant view from NASA’s New Horizons spacecraft. Their results may serve as ‘ground-truth’ observations to use as a baseline to interpret exoplanet direct-imaging data from future observatories. In this image, two three-dimensional shapes (top) of Uranus are
Viruses collected in a Northwestern University-led study are bacteriophages — a type of virus that infects and replicates inside of bacteria. The average American spends 93% of their time in built environments, almost 70% of that is in their place of residence. Human health and well-being are intrinsically tied to the quality of our personal
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

Weighted blankets can help to improve sleep in adults with insomnia and other mental health conditions, including anxiety and depression, but results are mixed for children, according to a new review paper published in The American Journal of Occupational Therapy. Dawson et al. suggest that occupational therapists should consider offering or recommending weighted blankets as
Early galaxies are dominated by bright clumps, which are larger and more massive than in the local Universe. The star formation activity is strongly influenced and can be even halted by a number of processes, some of which are directly related to the environment in which the galaxy resides. Ram pressure stripping, i.e. the removal

The challenge of powering energy-intensive AI data centers is a growing concern for companies like Microsoft and Oracle who are exploring options like nuclear power, but now, researchers from the Distance University of Madrid (UDIMA) in Spain and Mision Critica-Data Center in Bogotá, Colombia have approached the energy issue differently. Rather than focusing on powering
