On Jupiter’s icy moon Europa, powerful eruptions may spew into space, raising questions among hopeful astrobiologists on Earth: What would blast out from miles-high plumes? Could they contain signs of extraterrestrial life? And where in Europa would they originate? A new explanation now points to a source closer to the frozen surface than might be ...
The universe is getting hotter, a new study has found. The study, published in the Astrophysical Journal, probed the thermal history of the universe over the last 10 billion years. It found that the mean temperature of gas across the universe has increased more than 10 times over that time period and reached about 2 million degrees ...
Massive explosions of energy happening thousands of light-years from Earth, known as supernovas, may have left traces in our planet’s biology and geology, such as tree rings, according to new research by CU Boulder geoscientist Robert Brakenridge. The study, published this month in the International Journal of Astrobiology, probes the impacts of supernovas, some of the most ...
An international team of biologists, led by Monash University, has discovered a new species of extinct monk seal from the Southern Hemisphere — describing it as the biggest breakthrough in seal evolution in 70 years. The discovery, published in the Proceedings of the Royal Society, radically changes scientists’ understanding of how seal species evolved around the world. ...
Teacher-perceived conflicts in kindergarten predict a lower interest and pre-academic skills in math and literacy among kindergarteners, a new study from Finland shows. Kindergarten represents a crucial context in which children develop school-related skills and patterns of engagement that form the basis for the development of later competencies important for academic success. Kindergarten achievement has ...
New data from a Canadian-led team of astronomers, including researchers from the McGill Space Institute and McGill University Department of Physics, strongly suggest that magnetars — a type of neutron star believed to have an extremely powerful magnetic field — could be the source of some fast radio bursts (FRBs). Though much research has been done to explain ...
Older, large-diameter trees have been shown to store disproportionally massive amounts of carbon compared to smaller trees, highlighting their importance in mitigating climate change, according to a new study in Frontiers in Forests and Global Change. Researchers examined the aboveground carbon storage of large-diameter trees (>21 inches or >53.3 cm) on National Forest lands within Oregon ...
In the world of synthetic biology, the development of foundational components like logic gates and genetic clocks has enabled the design of circuits with increasing complexity, including the ability to solve math problems, build autonomous robots, and play interactive games. A team of researchers at the Georgia Institute of Technology is now using what they’ve ...
In a new study published in the journal Cell, an international research team has investigated the genetic, sociopolitical, and cultural changes that accompanied the emergence of the Central Asian empires. The team analyzed genome-wide data from 214 East Eurasian individuals spanning six millennia and discussed the changes in population and material culture that preceded the ...
A global study of ancient dog DNA, led by scientists at the Francis Crick Institute, University of Oxford, University of Vienna, and archaeologists from more than 10 countries, presents evidence that there were different types of dogs more than 11,000 years ago in the period immediately following the Ice Age. In their study, published in ...
