Solar Orbiter Sends Back Spectacular Images of the Sun

On March 26, 2022, the ESA/NASA Solar Orbiter spacecraft made the first of its close perihelion passages. The spacecraft flew closer to the Sun than the inner planet Mercury, achieving its closest approach at just 32% of the Earth’s distance from our star. Being that close to the Sun, the images, movies and data returned were spectacular. They show powerful flares, breathtaking views across the...

13,000-Year-Old Red Ocher Quarry Found in Wyoming

Intact artifacts and features found at the Powars II site, a red ocher (also known as hematite) quarry located in the foothills of the southern Rocky Mountains in Wyoming, demonstrate unequivocal evidence for red ocher quarrying by Paleoindians beginning 12,840 to 12,505 years ago, thus establishing Powars II as the oldest red ocher quarry identified in the Americas. Pelton et al. present results...

CERN Physicists Directly Observe Fundamental Phenomenon in Quantum Chromodynamics

In particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution is governed by the strong force, as described by the theory of quantum chromodynamics. These partons subsequently emit further partons in a process that can be described as a parton shower, which culminates in the formation of detectable hadrons....

Researchers Sequence Genome of Oat

Cultivated oat (Avena sativa) is an allohexaploid crop thought to have been domesticated more than 3,000 years ago while growing as a weed in wheat, emmer and barley fields in Anatolia. Oat has a low carbon footprint, substantial health benefits and the potential to replace animal-based food products. However, the lack of a fully annotated reference genome has hampered efforts to deconvolute its...

1.3-Billion-Year-Old Martian Meteorite Had Limited Exposure to Water, Study Finds

Using neutron and X-ray tomography, a team of planetary researchers from Lund University and elsewhere examined a section of Miller Range (MIL) 03346, a nakhlite meteorite from Miller Range in Antarctica. A polished section of the Martian meteorite Miller Range (MIL) 03346: (A) photograph of the interior of MIL 03346,230; note the yellow tint in the left region of the sample, marked by dotted lines;...

Rapid Global Warming is Driving Southern Yellow-Billed Hornbills to Local Extinction

In a study published in the journal Frontiers in Ecology and Evolution, a team of scientists in South Africa assessed the effects of air temperature and drought on the breeding output of southern yellow-billed hornbills (Tockus leucomelas) in the Kalahari Desert. The southern yellow-billed hornbill (Tockus leucomelas), adult female, in Mapungubwe National Park, South Africa. Image credit: Derek Keats...
