Published Why Jupiter doesn't have rings like Saturn
(via sciencedaily.com) Because it's bigger, Jupiter ought to have larger, more spectacular rings than Saturn has. But new research shows Jupiter's massive moons prevent that vision from lighting up the night sky.
Published Global map of lunar hydrogen: Data confirms role water played in moon's formation
(via sciencedaily.com) Original source Using data collected over two decades ago, scientists have compiled the first complete map of hydrogen abundances on the Moon's surface. The map identifies two types of lunar materials containing enhanced hydrogen and corroborates previous ideas about lunar hydrogen and water, including findings that water likely played a role in the Moon's original magma-ocean formation and solidification.
Published In search of the lost city of Natounia
(via sciencedaily.com) The mountain fortress of Rabana-Merquly in modern Iraqi Kurdistan was one of the major regional centers of the Parthian Empire, which extended over parts of Iran and Mesopotamia approximately 2,000 years ago. The researchers studied the remains of the fortress.
Published DNA from ancient population in Southern China suggests Native Americans' East Asian roots
(via sciencedaily.com) For the first time, researchers successfully sequenced the genome of ancient human fossils from the Late Pleistocene in southern China. The data suggests that the mysterious hominin belonged to an extinct maternal branch of modern humans that might have contributed to the origin of Native Americans.
Published What a Martian meteorite can teach us about Earth's origins
(via sciencedaily.com) What do Mars and Iceland have in common? These days, not so much. But more than 4.5 billion years ago, it's possible the Red Planet had a crust comparable to Iceland today. This discovery, hidden in the oldest martian fragments found on Earth, could provide information about our planet that was lost over billions of years of geological movement and could help explain why the Earth developed into a planet that sustains a broad diversity of life and Mars did not.
Published Rare deep-sea brine pools discovered in Red Sea
(via sciencedaily.com) Researchers recently discovered rare deep-sea brine pools in the Gulf of Aqaba, a northern extension to the Red Sea. These salty underwater lakes hold secrets into the way oceans on Earth formed millions of years ago, and offer clues to life on other planets.
Published Porosity of the moon's crust reveals bombardment history
(via sciencedaily.com) Researchers find that, early in its history, the moon was highly porous, which was likely a result of early, massive impacts that shattered much of the crust. They reached their conclusions with simulations and data from NASA's GRAIL mission.
Published Unlocking the secrets of the ancient coastal Maya
(via sciencedaily.com) After more than a decade of research, scientists share what they have learned about the people who lived on a stretch of coastline in Quintana Roo Mexico over a span of 3,000 years.
Published Study points to Armenian origins of ancient crop with aviation biofuel potential
(via sciencedaily.com) Camelina, an oilseed plant grown in modern-day Ukraine, may have been a more important and widespread crop than previously thought. New findings could inform breeding programs to improve this crop for biofuels applications.
Published Underwater jars reveal Roman period winemaking practices
(via sciencedaily.com) Winemaking practices in coastal Italy during the Roman period involved using native grapes for making wine in jars waterproofed with imported tar pitch, according to a new study.
Published Ice Age wolf DNA reveals dogs trace ancestry to two separate wolf populations
(via sciencedaily.com) An international group of geneticists and archaeologists have found that the ancestry of dogs can be traced to at least two populations of ancient wolves. The work moves us a step closer to uncovering the mystery of where dogs underwent domestication, one of the biggest unanswered questions about human prehistory.
Published The heat is on: Traces of fire uncovered dating back at least 800,000 years
(via sciencedaily.com) Original source Scientists reveal an advanced, innovative method that they have developed and used to detect nonvisual traces of fire dating back at least 800,000 years -- one of the earliest known pieces of evidence for the use of fire. The newly developed technique may provide a push toward a more scientific, data-driven type of archaeology, but -- perhaps more importantly -- it could help us better understand the origins of the human story, our most basic traditions and our experimental and innovative nature.
Published Indigenous communities used the Caribbean Sea as an aquatic highway
(via sciencedaily.com) Researchers recently turned to pottery to tease apart the navigational history of the Caribbean, analyzing the composition of 96 fired clay fragments across 11 islands. The study was conducted in the Greater Antilles and marks the first time that pottery artifacts from the Lucayan Islands -- The Bahamas plus the Turks and Caicos Islands -- have been analyzed to determine their elemental composition and origin.
Published Scientists map sulfur residue on Jupiter's icy moon Europa
(via sciencedaily.com) A team has used the Hubble Space Telescope to observe Jupiter's moon, Europa, at ultraviolet wavelengths, filling in a 'gap' in the various wavelengths used to observe this icy water world. The team's near-global UV maps show concentrations of sulfur dioxide on Europa's trailing side.
Published 1,700-year-old Korean genomes show genetic heterogeneity in Three Kingdoms period Gaya
(via sciencedaily.com) Scientists have successfully sequenced and studied the whole genome of eight 1,700-year-old individuals dated to the Three Kingdoms period of Korea (approx. 57 BC-668 AD). The first published genomes from this period in Korea and bring key information for the understanding of Korean population history.
Published Scientists identify a possible source for Charon's red cap
(via sciencedaily.com) Scientists combined data from NASA's New Horizons mission with novel laboratory experiments and exospheric modeling to reveal the likely composition of the red cap on Pluto's moon Charon and how it may have formed. This first-ever description of Charon's dynamic methane atmosphere using new experimental data provides a fascinating glimpse into the origins of this moon's red spot as described in two recent articles.
Published How elliptical craters could shed light on age of Saturn's moons
(via sciencedaily.com) A new study describes how unique populations of craters on two of Saturn's moons could help indicate the satellites' age and the conditions of their formation. Using data from NASA's Cassini mission, researchers have surveyed elliptical craters on Saturn's moons Tethys and Dione for this study.
Published A blueprint for life forms on Mars?
(via sciencedaily.com) Microbes taken from surface sediment near Lost Hammer Spring, Canada, about 900 km south of the North Pole, could provide a blueprint for the kind of life forms that may once have existed, or may still exist, on Mars.
Published More digging needed to see whether bones of fallen Waterloo soldiers were sold as fertilizer, as few human remains have ever been found
(via sciencedaily.com) Launched on the anniversary of the conflict, a new study suggests that mystery still surrounds what happened to the bodies of Waterloo militaries.
Published Martian meteorite upsets planet formation theory
(via sciencedaily.com) A new study of an old meteorite contradicts current thinking about how rocky planets like the Earth and Mars acquire volatile elements such as hydrogen, carbon, oxygen, nitrogen and noble gases as they form.
