Published Neolithic ceramics reveal dairy processing from milk of multiple species
(via sciencedaily.com) 
A new study has found evidence of cheesemaking, using milk from multiple animals in Late Neolithic Poland.
Published Lasers and chemistry reveal how ancient pottery was made -- and how an empire functioned
(via sciencedaily.com) 
Peru's first great empire, the Wari, stretched for more than a thousand miles over the Andes Mountains and along the coast from 600-1000 CE. The pottery they left behind gives archaeologists clues as to how the empire functioned. In a new study researchers showed that rather than using 'official' Wari pottery imported from the capital, potters across the empire were creating their own ceramics, decorated to emulate the traditional Wari style. To figure it out, the scientists analyzed the pottery's chemical make-up, with help from laser beams.
Published Thousands of native plants are unphotographed, and citizen scientists can help fill the gaps
(via sciencedaily.com) 
New research finds almost 4000 Australian plant species have not been photographed before in the wild, which may lead to their extinction.
Published Brown widow spiders' aggression likely driver of black widow decline
(via sciencedaily.com) 
Black widow spiders have earned a fearsome reputation for their venomous bite. But in parts of the southern United States these spiders have much to fear themselves -- from spider relatives who really don't like their company. In the past couple decades, researchers have noticed black widow spiders being displaced by the brown widow, a fellow species in the same genus. But new research suggests this isn't a simple case of one species winning the competition for food or habitat. Instead, a study shows brown widow spiders have a striking propensity to seek out and kill nearby black widows.
Published Surprising similarities in stone tools of early humans and monkeys
(via sciencedaily.com) 
Researchers have discovered artefacts produced by old world monkeys in Thailand that resemble stone tools, which historically have been identified as intentionally made by early hominins. Until now, sharp-edged stone tools were thought to represent the onset of intentional stone tool production, one of the defining and unique characteristics of hominin evolution. This new study challenges long held beliefs about the origins of intentional tool production in our own lineage.
Published Remarkable squirting mussels captured on film
(via sciencedaily.com) 
Researchers have observed a highly unusual behavior in the endangered freshwater mussel, Unio crassus. The jets disturb the river surface and attract fish. Mussel larvae in the jets can then attach to the gills of the fish and complete their metamorphosis into adults.
Published Eiphosoma laphygmae likely to be best classical biological control against devastating fall armyworm pest
(via sciencedaily.com) 
A review suggests that the parasitoid Eiphosoma laphygmae is likely to be the best classical biological control from the Americas against the devastating fall armyworm pest.
Published eDNA holds the key to safeguarding pollinators amid global declines
(via sciencedaily.com) 
Researchers have uncovered new evidence of western pygmy possums interacting with native flowers, providing an eDNA study to simultaneously detect mammal, insect and bird DNA on flowers.
Published To help dry forests, fire needs to be just the right intensity, and happen more than once
(via sciencedaily.com) 
Research into the ability of a wildfire to improve the health of a forest uncovered a Goldilocks effect -- unless a blaze falls in a narrow severity range, neither too hot nor too cold, it isn't very good at helping forest landscapes return to their historical, more fire-tolerant conditions.
Published The world's first horse riders
(via sciencedaily.com) 
Researchers have discovered evidence of horse riding by studying the remains of human skeletons found in burial mounds called kurgans, which were between 4500-5000 years old. The earthen burial mounds belonged to the Yamnaya culture. The Yamnayans had migrated from the Pontic-Caspian steppes to find greener pastures in today's countries of Romania and Bulgaria up to Hungary and Serbia.
Published Archaeological study of 24 ancient Mexican cities reveals that collective forms of governance, infrastructural investments, and collaboration all help societies last longer
(via sciencedaily.com) 
Some cities only last a century or two, while others last for a thousand years or more. Often, there aren't clear records left behind to explain why. Instead, archaeologists piece together clues from the cities' remains to search for patterns that help account for why certain places retained their importance longer than others.
Published Wisconsin cave holds tantalizing clues to ancient climate changes, future shifts
(via sciencedaily.com) 
A newly published study of a stalagmite found in Cave of the Mounds reveals previously undetected history of the local climate going back thousands of years. Researchers describe evidence for an ice age punctuated by massive and abrupt warming events across much of the Northern Hemisphere.
Published Bronze Age well contents reveal the history of animal resources in Mycenae, Greece
(via sciencedaily.com)
Original source 
A large Bronze Age debris deposit in Mycenae, Greece provides important data for understanding the history of animal resources at the site, according to a new study.
Published Waxing and waning of environment influences hominin dispersals across ancient Iran
(via sciencedaily.com) 
A world-first model of paleoclimate and hydrology in Iran has highlighted favourable routes for Neanderthals and modern human expansions eastwards into Asia. The findings reveal that multiple humid periods in ancient Iran led to the expansions of human populations, opening dispersal route across the region, and the possible interactions of species such as Neanderthals and our own Homo sapiens.
Published Deforestation in the tropics linked to a reduction in rainfall
(via sciencedaily.com) 
Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.
Published Oldest human genome from southern Spain
(via sciencedaily.com) 
A new study reports on genomic data from a 23,000-year-old individual who lived in what was probably the warmest place of Europe at the peak of the last Ice Age. The oldest human genome recovered from the southern tip of Spain adds an important piece of the puzzle to the genetic history of Europe.
Published Steel was being used in Europe 2900 years ago
(via sciencedaily.com) 
Researchers have discovered what they believe is the earliest use of steel in Europe -- on Iberian stone pillars from the Final Bronze Age.
Published Mysterious new behavior seen in whales may be recorded in ancient manuscripts
(via sciencedaily.com) 
In 2011, scientists recorded a previously unknown feeding strategy in whales around the world. Now, researchers in Australia think they may have found evidence of this behaviour being described in ancient accounts of sea creatures, recorded more than 2,000 years ago. They believe that misunderstandings of these descriptions contributed to myths about medieval sea monsters. Whales are known lunge at their prey when feeding, but recently whales have been spotted at the surface of the water with their jaws open at right angles, waiting for shoals of fish to swim into their mouths. A clip of this strategy was captured in 2021 and went viral on Instagram. This strategy seems to work for the whales because the fish think they have found a place to shelter from predators, not realising they are swimming into danger. It's not known why this strategy has only recently been identified, but scientists speculate that it's a result of changing environmental conditions -- or that whales are being more closely monitored than ever before by drones and other modern technologies.

Ants play a key role in forest regeneration, according to a new article.
