A team of researchers has recreated one of the scents used in the mummification of an important Egyptian woman more than 3500 years ago.
Published Evolutionary imbalance explains global plant invasions
(via sciencedaily.com)
Original source 
Plant species from certain geographic regions are more successful in spreading outside their native ranges than others -- but why? Ecologists provide answers by exploring how the ecological and evolutionary histories of plants can influence their relationships with humans and their success as invaders.
Published Coastal fisheries show surprising resilience to marine heat waves
(via sciencedaily.com) 
New research found that marine heat waves -- prolonged periods of unusually warm ocean temperatures -- haven't had a lasting effect on the fish communities that feed most of the world. The finding is in stark contrast to the devastating effects seen on other marine ecosystems cataloged by scientists after similar periods of warming, including widespread coral bleaching and harmful algal blooms.
Published Algae provide clues about 600 million years of plant evolution
(via sciencedaily.com)
Original source 
Researchers generated large scale gene expression data to investigate the molecular networks that operate in one of the closest algal relatives of land plants, a humble single-celled alga called Mesotaenium endlicherianum.
Published Can this forest survive? Predicting forest death or recovery after drought
(via sciencedaily.com)
Original source 
New work could help forest managers predict which forests are most at risk from drought and which will survive.
Published Wastewater pipe dig reveals 'fossil treasure trove'
(via sciencedaily.com)
Original source 
A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.
Published Researchers extract ancient DNA from a 2,900-year-old clay brick, revealing a time capsule of plant life
(via sciencedaily.com)
Original source 
For the first time, a group of researchers have successfully extracted ancient DNA from a 2,900-year-old clay brick. The analysis provides a fascinating insight into the diversity of plant species cultivated at that time and place, and could open the way to similar studies on clay material from other sites and time periods.
Published Ancient metal cauldrons give us clues about what people ate in the Bronze Age
(via sciencedaily.com)
Original source 
Archaeologists have long been drawing conclusions about how ancient tools were used by the people who crafted them based on written records and context clues. But with dietary practices, they have had to make assumptions about what was eaten and how it was prepared. A new study analyzed protein residues from ancient cooking cauldrons and found that the people of Caucasus ate deer, sheep, goats, and members of the cow family during the Maykop period (3700--2900 BCE).
Published Unveiling Japan's ancient practice of cranial modification: The case of the Hirota people in Tanegashima
(via sciencedaily.com)
Original source 
Cranial modification is a form of body alteration where the head is pressed or bound to permanently deform the skull. The practice has been reported across various cultures throughout history. Researchers report that the Hirota people -- who lived on the southern Japanese island of Tanegashima between the 3rd to 7th century CE -- also conducted cranial modification, with indication that both males and females performed the practice.
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 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 '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 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 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.
