Thousands of years ago, early hunter-gatherers returned regularly to Tagua Tagua Lake in Chile to hunt ancient elephants and take advantage of other local resources, according to a new study.

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.

The analysis of fat traces in over one hundred pottery vessels reveals deep changes in food consumption and preparation by communities living in central Germany between the Early Neolithic and the Late Bronze Age, as well as in their relation with innovations in pottery styles and decorations. In a groundbreaking study, researchers identified a generalized inclusion of dairy products in prehistoric diets, a preference in consuming pork with the arrival of communities from the Eurasian Steppe, and the importance of dairy products in funeral rites. Central Germany was a key region for the emergence of great prehistoric cultures, such as the Linear Pottery Culture, the Corded Ware Culture, the Bell Beaker populations and the Unetice Culture, one of the first state societies in Europe.

The study's findings show mergansers arrived in the New Zealand region at least seven million years ago from the Northern Hemisphere, in a separate colonisation event to that which led to the Brazilian merganser.

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.

Sarcasm is notoriously tricky to convey through text, and the subtle changes in tone that convey sarcasm often confuse computer algorithms as well, limiting virtual assistants and content analysis tools. So researchers have now developed a multimodal algorithm for improved sarcasm detection that examines multiple aspects of audio recordings for increased accuracy. They used two complementary approaches -- sentiment analysis using text and emotion recognition using audio -- for a more complete picture.

New research finds that, while an increasing number of minors are using virtual reality (VR) apps, not many parents recognize the extent of the security and privacy risks that are specific to VR technologies. The study also found that few parents are taking active steps to address those security and privacy issues, such as using parental controls built into the apps.

In the sports industry, player data collection aids in personalized training feedback. Researchers have now gathered a detailed dataset and laid the foundation for delivering coaching assistance and feedback through the same. Utilizing wearable sensors and machine learning, their dataset offers real-time feedback and optimized movement suggestions. With over 7,763 badminton swings analyzed, stroke quality assessment offers valuable insights, making badminton training more accessible and affordable.

Researchers have developed a compact, single-shot polarization imaging system that can provide a complete picture of polarization. By using just two thin metasurfaces, the imaging system could unlock the vast potential of polarization imaging for a range of existing and new applications, including biomedical imaging, augmented and virtual reality systems and smart phones.

Working with teens, researchers designed RESeT: a snowy virtual world with six activities intended to improve mood. In a 3-week study of 44 teens, researchers found that most of the teens used the technology about twice a week without being prompted and reported lower stress levels after using the environment.

It has long been thought that meat played an important role in the diet of hunter-gatherers before the Neolithic transition. However, due to the scarcity of well-preserved human remains from Paleolithic sites, little information exists about the dietary habits of pre-agricultural human groups. A new study challenges this notion by presenting compelling isotopic evidence of a strong preference for plants among 15,000-year-old hunter-gatherers from Morocco. This is the first time a significant amount of plant consumption has been measured for a pre-agricultural population, shedding new light on the dietary practices of ancient human societies.

Using environmental DNA analysis, an international team of researchers identified a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah in Mexico. The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor where a ballcourt was built.

Crossing roads for children can be a risky calculation, especially when the vehicles are self-driven. In a new study, researchers determined pre-teenage children are safest when self-driving vehicles signaled their intent to yield with a green light when they arrived at the intersection, then stopped.
