Ancient source of oxygen for life hidden deep in the Earth’s crust — ScienceDaily

Scientists at Newcastle University have discovered a source of oxygen that may have influenced the evolution of life before the advent of photosynthesis. The pioneering research project, led by Newcastle University’s School of Natural and Environmental Sciences and published today in Nature Communications, uncovered a mechanism that can generate hydrogen peroxide from rocks during the … Read more

Hibernation slows biological aging in bats — ScienceDaily

The most common bat in the United States, the big brown bat, boasts an unusually long lifespan of up to 19 years. A new study led by University of Maryland researchers identifies one of the secrets to this bat’s exceptional longevity: hibernation. “Hibernation has allowed bats, and presumably other animals, to stay in northern or … Read more

Evidence that giant meteorite impacts created the continents — ScienceDaily

New Curtin research has provided the strongest evidence yet that Earth’s continents were formed by giant meteorite impacts that were particularly prevalent during the first billion years or so of our planet’s four-and-a-half-billion year history. Dr Tim Johnson, from Curtin’s School of Earth and Planetary Sciences, said the idea that the continents originally formed at … Read more

Researchers ID the high-efficiency hacks cannabis cells use to make cannabinoids — ScienceDaily

For the first time, plant biologists have defined the high-efficiency “hacks” that cannabis cells use to make cannabinoids (THC/CBD). Although many biotechnology companies are currently trying to engineer THC/CBD outside the plant in yeast or cell cultures, it is largely unknown how the plant does it naturally. “This really helps us understand how the cells … Read more

Modeling reveals how dwarf planet Ceres powers unexpected geologic activity — ScienceDaily

For a long time, our view of Ceres was fuzzy, said Scott King, a geoscientist in the Virginia Tech College of Science. A dwarf planet and the largest body found in the asteroid belt — the region between Jupiter and Mars speckled with hundreds of thousands of asteroids — Ceres had no distinguishable surface features … Read more

Brain development differs between Neanderthals and modern humans — ScienceDaily

Neanderthals are the closest relatives to modern humans. Comparisons with them can therefore provide fascinating insights into what makes present-day humans unique, for example regarding the development of the brain. The neocortex, the largest part of the outer layer of the brain, is unique to mammals and crucial for many cognitive capacities. It expanded dramatically … Read more

New paleomagnetic research suggests Earth’s solid inner core formed 550 million years ago and restored our planet’s magnetic field — ScienceDaily

Approximately 1,800 miles beneath our feet, swirling liquid iron in the Earth’s outer core generates our planet’s protective magnetic field. This magnetic field is invisible but is vital for life on Earth’s surface because it shields the planet from solar wind — streams of radiation from the sun. About 565 million years ago, however, the … Read more

The bigger the temperature change, the larger the extinction event — ScienceDaily

A professor emeritus at Tohoku University has unearthed evidence pointing to a strong relationship between the magnitude of mass extinctions and global temperature changes in geological times. The research was published in the journal Biogeosciences on July, 22, 2022. Abrupt climate change, accompanied by environmental destruction from large volcanic eruptions and meteorites, has caused major … Read more

Off-axis high-temperature hydrothermal field discovered at the East Pacific Rise 9°54’N — ScienceDaily

Spearheaded by the McDermott lab at Lehigh, the research demonstrates there are more hydrothermal vents in the deep-sea than previously thought and underscores a need for bathymetric mapping to locate them. Finding a new, high-temperature, off-axis hydrothermal vent field on the floor of the Pacific Ocean at 2,550 meters depth could change scientists’ understanding of … Read more

New method to map the surface of the moon increases accuracy to unprecedented levels — ScienceDaily

Topography: The surface of the moon and rocky planets, Mars in particular, are of huge interest to anyone trying to explore our solar system. The surface must be known in as much detail as possible, for missions to land safely, or for any robotic vessel to drive across the surface. But until now, the methods … Read more
