New study says we"re unlikely to find liquid water on Mars anytime soon
More than a hundred years ago, astronomer Percival Lowell made the case for the existence of canals on Mars designed to redistribute water from the Martian ice caps to its lower, drier latitudes. This necessarily meant the existence of Martians to bu.....»»
Simulation sheds light on Earth"s magnetic field generation while advancing neuromorphic computing
How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain unresolved. A team of researchers from the Center for Advanced Systems Understanding at the Helmholtz-Zentrum Dresden-Rossendorf, Sa.....»»
We developed a way to use light to dismantle PFAS "forever chemicals"
Perfluoroalkyl and polyfluoroalkyl substances, or PFAS, have earned the nickname of forever chemicals from their extraordinary ability to stick around in the environment long after they've been used......»»
Twins were the norm for our ancient primate ancestors—one baby at a time had evolutionary advantages
Twins have been rare in human history and for that reason can seem special. Many cultures associate twins with health and vitality, while others see them as a philosophical reminder of the duality of life and death, good and evil. Some famous twins a.....»»
What 92 years of data say about ice cover
Warming air temperatures are changing ice cover in seasonally frozen lakes worldwide. The timing of ice formation and melting, called ice phenology, affects lake temperatures, seasonal stratification, and lake ecology, though much about these dynamic.....»»
New data from "the last ice area" may help long-term conservation efforts in the Arctic
Earlier this year our international team of scientists from the Refuge Arctic consortium departed Iqaluit, Nvt. on a 56-day research expedition in the far north. We were sailing aboard the icebreaker CCGS Amundsen and our main objective was to study.....»»

The spiral galaxy NGC 5643 is located roughly 40 million light-years away in the constellation Lupus, the Wolf. NGC 5643 is a grand design spiral, which refers to the galaxy's symmetrical form with two large, winding spiral arms that are clearly visi.....»»
Does the exoplanet TRAPPIST-1 b have an atmosphere after all?
TRAPPIST-1 b is one of seven rocky planets orbiting the star TRAPPIST-1, located 40 light-years away. The planetary system is unique because it allows astronomers to study seven Earth-like planets from relatively close range, with three of them in th.....»»
Butchered bones suggest violent "othering" of enemies in Bronze Age Britain
Archaeologists have analyzed more than 3,000 human bones and bone fragments from the Early Bronze Age site of Charterhouse Warren, England, concluding that the people were massacred, butchered, and likely partly consumed by enemies as a means to dehu.....»»
