New open-source platform allows users to evaluate performance of AI-powered chatbots      (via sciencedaily.com)     Original source 

Researchers have developed a platform for the interactive evaluation of AI-powered chatbots such as ChatGPT. A team of computer scientists, engineers, mathematicians and cognitive scientists developed an open-source evaluation platform called CheckMate, which allows human users to interact with and evaluate the performance of large language models (LLMs).

Unraveling the physics of knitting      (via sciencedaily.com)     Original source 

A team used experiments and simulations to quantify and predict how knit fabric response can be programmed. By establishing a mathematical theory of knitted materials, the researchers hope that knitting -- and textiles in general -- can be incorporated into more engineering and manufacturing applications.

The embryo assembles itself      (via sciencedaily.com)     Original source 

Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of birds. Interestingly, the mammalian embryo develops similarly. Scientists now introduce a mathematical framework that analyzes self-organization from a single cell to a multicellular organism.

Groundbreaking progress in quantum physics: How quantum field theories decay and fission      (via sciencedaily.com)     Original source 

An international research team has sparked interest in the scientific community with results in quantum physics. In their current study, the researchers reinterpret the Higgs mechanism, which gives elementary particles mass and triggers phase transitions, using the concept of 'magnetic quivers.'

Crucial shift in River Nile's evolution during ancient Egypt discovered      (via sciencedaily.com)     Original source 

Researchers have explored how the River Nile evolved over the past 11,500 years and how changes in its geography could have helped shape the fortunes of ancient Egyptian civilization. Research reveals a major shift in the Nile around four thousand years ago, after which the floodplain in the Nile Valley around Luxor greatly expanded.

Kinship and ancestry of the Celts in Baden-Württemberg, Germany      (via sciencedaily.com)     Original source 

The Celtic culture of the pre-Roman Iron Age in Western and Central Europe has left numerous traces to this day, not least in the form of enormous burial mounds and spectacular archaeological artifacts. Despite this rich legacy, much about this civilization remains hidden from us.

Could the world famous Roman Baths help scientists counter the challenge of antibiotic resistance?      (via sciencedaily.com)     Original source 

A new study has uncovered a diverse array of microorganisms within the hot waters of the Roman Baths, regularly listed among the UK's most popular tourist attractions. Tests showed 15 of the isolated bacteria -- including examples of Proteobacteria and Firmicutes -- displayed varying levels of inhibition against human pathogens including E.coli, Staphylococcus Aureus and Shigella flexneri.

AI-controlled stations can charge electric cars at a personal price      (via sciencedaily.com)     Original source 

As more and more people drive electric cars, congestion and queues can occur when many people need to charge at the same time. A new study shows how AI-controlled charging stations, through smart algorithms, can offer electric vehicle users personalized prices, and thus minimize both price and waiting time for customers. But the researchers point to the importance of taking the ethical issues seriously, as there is a risk that the artificial intelligence exploits information from motorists.

Excavation reveals 'major' ancient migration to Timor Island      (via sciencedaily.com)     Original source 

The discovery of thousands of stone artefacts and animal bones in a deep cave in Timor Island has led archaeologists to reassess the route that early humans took to reach Australia. Researchers dated and analysed the artefacts and sediment at the Laili rock shelter in central-north Timor-Leste, north of Australia, to pinpoint the arrival of the colonists.

Pagan-Christian trade networks supplied horses from overseas for the last horse sacrifices in Europe      (via sciencedaily.com)     Original source 

Horses crossed the Baltic Sea in ships during the Late Viking Age and were sacrificed for funeral rituals. Studies on the remains of horses found at ancient burial sites in Russia and Lithuania show that they were brought overseas from Scandinavia utilizing expansive trade networks connecting the Viking world with the Byzantine and Arab Empires. Up to now, researchers had believed sacrificial horses were always locally-sourced stallions. But these results reveal horses from modern Sweden or Finland traveled up to 1,500 km across the Baltic Sea. The findings also show that the sex of the horse was not necessarily a factor in them being chosen for sacrifice, with genetic analysis showing one in three were mares.

Early arrival and expansion of palaeolithic people on Cyprus      (via sciencedaily.com)     Original source 

The patterns of dispersal of early humans across continents and islands are hotly debated, but researchers have found that Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought. In examining the timing of the first human occupation of Cyprus, research found that large islands in the Mediterranean Sea were attractive and favorable destinations for palaeolithic peoples. These findings refute previous studies that suggested Mediterranean islands would have been unreachable and inhospitable for Pleistocene hunter-gatherer societies.
