Ritual sacrifice at Chichén Itzá      (via sciencedaily.com)     Original source 

Rising to power in the wake of the Classic Maya collapse, Chichen Itz was among the largest and most influential cities of the ancient Maya, but much about its political connections and ritual life remain poorly understood. Close kin relationships, including two pairs of identical twins, suggests a connection to the Maya origin myths of the Popol Vuh.

Wind from black holes may influence development of surrounding galaxies      (via sciencedaily.com)     Original source 

Clouds of gas in a distant galaxy are being pushed faster and faster -- at more than 10,000 miles per second -- out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy's center. It's a discovery that helps illuminate the way active black holes can continuously shape their galaxies by spurring on or snuffing out the development of new stars.

Scientists spot more Milky Way-like galaxies in early universe      (via sciencedaily.com)     Original source 

Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of years ago. The astronomers have discovered that spiral galaxies were more common in the early universe than previously thought. The scientists found that nearly 30% of galaxies have a spiral structure about 2 billion years after the universe formed. The discovery provides a significant update to the universe's origin story as previously told using data from NASA's Hubble Space Telescope.

Origins of fast radio bursts come into focus through polarized light      (via sciencedaily.com)     Original source 

What scientists previously thought about where Fast Radio Bursts (FRBs) come from is just the tip of the iceberg. A new study details the properties of polarized light from 128 non-repeating FRBs and reveals mysterious cosmic explosions that originated in far-away galaxies, similar to our own Milky Way.

Shedding light on the origin of a genetic variant underlying fungal infections      (via sciencedaily.com)     Original source 

Variants in the CARD9 gene increase susceptibility to severe fungal infections. However, individuals in different parts of the world tend to carry specific CARD9 variants, making it complex to track the origin of these mutations. In a recent study, a research team conducted genetic analyses on Japanese, Korean, and Chinese patients, revealing that they all shared a variant of CARD9 stemming from a common ancestor from less than 4,000 years ago.

How did a satellite galaxy of the Milky Way come to be?      (via sciencedaily.com)     Original source 

Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface brightness. How this galaxy originated remains unclear. A team of physicists now offers an explanation.

NASA's Webb opens new window on supernova science      (via sciencedaily.com)     Original source 

Peering deeply into the cosmos, NASA's James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the early universe than were previously known. A few of the newfound exploding stars are the most distant examples of their type, including those used to measure the universe's expansion rate.

Exotic black holes could be a byproduct of dark matter      (via sciencedaily.com)     Original source 

In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose. The gravitational pull from these tiny, invisible objects could potentially explain all the dark matter that we can't see today.

Researchers solve 2,000-year-old mystery of the shipworm      (via sciencedaily.com)     Original source 

They bedeviled ancient Greek navies, helped shipwreck Christopher Columbus, aided in the sinking of the Spanish Armada and caused the wharves in San Francisco Bay to collapse into the sea, but until now, scientists have been unable to pinpoint exactly how shipworms -- a family of mollusks -- are able to cause such damage. A team of researchers has discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the gut called the 'typhlosole,' have the ability to secrete the enzymes needed to digest lignin -- the toughest part of wood.
