Published Bridging traditional economics and econophysics
(via sciencedaily.com)
Original source 
How do asset markets work? Which stocks behave similarly? Economists, physicists, and mathematicians work intensively to draw a picture but need to learn what is happening outside their discipline. A new paper now builds a bridge.
Published Study shows ancient Alaskans were freshwater fishers
(via sciencedaily.com)
Original source 
A scientific team has discovered the earliest-known evidence of freshwater fishing by ancient people in the Americas. The research offers a glimpse at how early humans used a changing landscape and could offer insight for modern people facing similar changes.
Published High-quality child care contributes to later success in science, math
(via sciencedaily.com)
Original source 
Children who receive high-quality child care as babies, toddlers and preschoolers do better in science, technology, engineering and math through high school, and that link is stronger among children from low-income backgrounds, according to new research.
Published Remains at Crenshaw site are local, ancestors of Caddo
(via sciencedaily.com)
Original source 
Hundreds of human skulls and mandibles recovered from the Crenshaw site in southwest Arkansas are the remains of ancestors of the Caddo Nation and not foreign enemies, according to a new study.
Published A step toward safe and reliable autopilots for flying
(via sciencedaily.com)
Original source 
Researchers developed a machine-learning technique that can autonomously drive a car or fly a plane through a very difficult 'stabilize-avoid' scenario, in which the vehicle must stabilize its trajectory to arrive at and stay within some goal region, while avoiding obstacles.
Published Lingering effects of Neanderthal DNA found in modern humans
(via sciencedaily.com)
Original source 
Recent scientific discoveries have shown that Neanderthal genes comprise some 1 to 4% of the genome of present-day humans whose ancestors migrated out of Africa, but the question remained open on how much those genes are still actively influencing human traits -- until now.
Published AI-generated academic science writing can be identified with over 99% accuracy
(via sciencedaily.com)
Original source 
The debut of artificial intelligence chatbot ChatGPT has set the world abuzz with its ability to churn out human-like text and conversations. Still, many telltale signs can help us distinguish AI chatbots from humans, according to a new study. Based on the signs, the researchers developed a tool to identify AI-generated academic science writing with over 99% accuracy.
Published Applying artificial intelligence for early risk forecasting of Alzheimer's disease
(via sciencedaily.com)
Original source 
An international research team has developed an artificial intelligence (AI)-based model that uses genetic information to predict an individual's risk of developing Alzheimer's disease (AD) well before symptoms occur. This groundbreaking study paves the way for using deep learning methods to predict the risks of diseases and uncover their molecular mechanisms; this could revolutionize the diagnosis of, interventions for, and clinical research on AD and other common diseases such as cardiovascular diseases.
Published New AI boosts teamwork training
(via sciencedaily.com)
Original source 
Researchers have developed a new artificial intelligence (AI) framework that is better than previous technologies at analyzing and categorizing dialogue between individuals, with the goal of improving team training technologies. The framework will enable training technologies to better understand how well individuals are coordinating with one another and working as part of a team.
Published The digital dark matter clouding AI
(via sciencedaily.com)
Original source 
Scientists using artificial intelligence technology may be inviting unwanted noise into their genome analyses. Now, researchers have created a computational correction that will allow them to see through the fog and find genuine DNA features that could signal breakthroughs in health and medicine.
Published Finally solved! The great mystery of quantized vortex motion
(via sciencedaily.com)
Original source 
Scientists investigated numerically the interaction between a quantized vortex and a normal-fluid. Based on the experimental results, researchers decided the most consistent of several theoretical models. They found that a model that accounts for changes in the normal-fluid and incorporates more theoretically accurate mutual friction is the most compatible with the experimental results.
Published New method improves efficiency of 'vision transformer' AI systems
(via sciencedaily.com)
Original source 
Vision transformers (ViTs) are powerful artificial intelligence (AI) technologies that can identify or categorize objects in images -- however, there are significant challenges related to both computing power requirements and decision-making transparency. Researchers have now developed a new methodology that addresses both challenges, while also improving the ViT's ability to identify, classify and segment objects in images.
Published Using AI, scientists find a drug that could combat drug-resistant infections
(via sciencedaily.com)
Original source 
Using AI, researchers identified a new antibiotic that can kill Acinetobacter baumannii, a type of bacteria that is responsible for many drug-resistant infections.
Published Scientists propose revolution in complex systems modelling with quantum technologies
(via sciencedaily.com)
Original source 
Scientists have made a significant advancement with quantum technologies that could transform complex systems modelling with an accurate and effective approach that requires significantly re-duced memory.
Published New method predicts extreme events more accurately
(via sciencedaily.com)
Original source 
A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.
Published Earliest evidence of wine consumption in the Americas found in Caribbean
(via sciencedaily.com)
Original source 
Scientists have found what they believe to be the earliest known evidence of wine drinking in the Americas, inside ceramic artefacts recovered from a small Caribbean island.
Published Ancient climate change solves mystery of vanished South African lakes
(via sciencedaily.com)
Original source 
New evidence for the presence of ancient lakes in some of the most arid regions of South Africa suggests that Stone Age humans may have been more widespread across the continent than previously thought.
Published Oldest architectural plans detail mysterious desert mega structures
(via sciencedaily.com)
Original source 
Researchers have identified engravings in Jordan and Saudi Arabia as the oldest known scaled building plans in human history.
Published Humanity's earliest recorded kiss occurred in Mesopotamia 4,500 years ago
(via sciencedaily.com)
Original source 
Written sources from Mesopotamia suggest that kissing in relation to sex was practiced by the peoples of the ancient Middle East 4,500 years ago.
Published A better way to study ocean currents
(via sciencedaily.com)
Original source 
Computer scientists and oceanographers developed a machine-learning model that generates more accurate predictions about the velocities of ocean currents. The model could help make more precise weather forecasts or effectively predict how oil will spread after a spill.
