Published Sea sequin 'bling' links Indonesian islands' ancient communities
(via sciencedaily.com) Original source Microscopic analysis has revealed that trends in body ornamentation were shared across Indonesian islands.
Published China's oldest water pipes were a communal effort
(via sciencedaily.com) Original source A system of ancient ceramic water pipes, the oldest ever unearthed in China, shows that neolithic people were capable of complex engineering feats without the need for a centralized state authority, finds a new study.
Published Fossil feces infested with parasites from over 200 million years ago
(via sciencedaily.com) Original source Fossilized feces preserve evidence of ancient parasites that infected an aquatic predator over 200 million years ago, according to a new study.
Published Roman road network spanning the South West identified in new research
(via sciencedaily.com) Original source New research has found evidence that a Roman road network spanned Devon and Cornwall and connected significant settlements with military forts across the two counties as well as wider Britannia.
Published In the treetops: Ecologist studies canopy soil abundance, chemistry
(via sciencedaily.com) Original source Ecologists examined the distribution patterns of canopy soils, and their soil properties, across Costa Rican forests. The researchers suggest canopy soil may store more carbon than previously thought. Consideration of the time needed for reforestation of system with tree canopies should include the time needed for canopy mat regrowth.
Published Tropical trees use social distancing to maintain biodiversity
(via sciencedaily.com) Original source Tropical forests can harbor hundreds of species of trees in one square mile. Researchers reveal key factors in the spatial distribution of adult trees.
Published Using gemstones' unique characteristics to uncover ancient trade routes
(via sciencedaily.com) Original source Gems' unique elemental composition and atomic orientation act as a fingerprint, enabling researchers to uncover the stones' past, and with it, historical trade routes. Scientists now employ three modern spectroscopic techniques to rapidly analyze gems found in the Arabian-Nubian Shield and compare them with similar gems from around the world. They have identified elements that influence gems' color, differentiated stones found within and outside the region, and distinguished natural from synthetic.
Published Plans to plant billions of trees threatened by massive undersupply of seedlings
(via sciencedaily.com) Original source Major government and private funding is being invested in planting trees as a powerful tool to fight climate change. But new research shows a troubling bottleneck that could threaten these efforts: U.S. tree nurseries don't grow close to enough trees--nor have the species diversity needed--to meet ambitious planting and restoration goals.
Published 'Time-traveling' pathogens in melting permafrost pose likely risk to environment
(via sciencedaily.com) Original source Ancient pathogens that escape from melting permafrost have real potential to damage microbial communities and might potentially threaten human health, according to a new study.
Published New study reveals that tree species diversity increases spider density
(via sciencedaily.com) Original source The link between tree diversity and spider populations can help homeowners and other land managers better plan tree plantings to naturally mitigate the effects of climate change.
Published New insights into the origin of the Indo-European languages
(via sciencedaily.com) Original source An international team of linguists and geneticists has achieved a significant breakthrough in our understanding of the origins of Indo-European, a family of languages spoken by nearly half of the world's population.
Published Ancient DNA reveals diverse community in 'Lost City of the Incas'
(via sciencedaily.com) Original source DNA analysis of 34 individuals buried at Machu Picchu revealed that many traveled alone from throughout the Inca Empire.
Published Family trees from the European Neolithic
(via sciencedaily.com) Original source The Neolithic burial site of Gurgy 'les Noisats' in France revealed two unprecedentedly large family trees which allowed a Franco-German team to explore the social organization of the 6,700-year-old community. Based on multiple lines of evidence, the team describes a close kin group which practiced monogamy and female exogamy, and experienced generally stable times.
Published Missing island explains how endemic species on the Miyako Islands emerged
(via sciencedaily.com) Original source Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.
Published Research supports use of managed and prescribed fires to reduce fire severity
(via sciencedaily.com) Original source Scientists found that fires in America's dry conifer forests are burning hotter and killing more trees today than in previous centuries. The main culprit? Paradoxically, a lack of fires.
Published Miocene period fossil forest of Wataria found in Japan
(via sciencedaily.com) Original source An exquisitely preserved fossil forest from Japan provides missing links and helps reconstruct a whole Eurasia plant from the late Miocene epoch.
Published Gene variation makes apple trees 'weep,' improving orchards
(via sciencedaily.com) Original source Plant geneticists have identified a mutation in a gene that causes the 'weeping' architecture -- branches growing downwards -- in apple trees, a finding that could improve orchard fruit production.
Published Picky green sea turtle has travelled to the same place to eat for generations
(via sciencedaily.com) Original source For approximately 3,000 years, generations of green sea turtles have returned to the same seagrass meadows to eat. The fact that this stretches over many generations highlights the importance of protecting seagrass meadows along the coasts of North Africa.
Published Building a better forest tree with CRISPR gene editing
(via sciencedaily.com) Original source Researchers use CRISPR techniques to modify lignin levels in poplar trees.
Published Hidden details of Egyptian paintings revealed by chemical imaging
(via sciencedaily.com) Original source Portable chemical imaging technology can reveal hidden details in ancient Egyptian paintings, according to new research.
