Maths: Smart learning software helps children during lockdowns -- and beyond      (via sciencedaily.com)     Original source 

Intelligent tutoring systems for math problems helped pupils remain or even increase their performance during the coronavirus pandemic, according to a new study. Researchers analyzed data from five million exercises done by around 2,700 pupils in Germany over a period of five years. The study found that particularly lower-performing children benefit if they use the software regularly.

What math tells us about social dilemmas      (via sciencedaily.com)     Original source 

Human coexistence depends on cooperation. Individuals have different motivations and reasons to collaborate, resulting in social dilemmas, such as the well-known prisoner's dilemma. Scientists now present a new mathematical principle that helps to understand the cooperation of individuals with different characteristics.

Plant seed and fruit analysis from the biblical home of Goliath sheds unprecedented light on Philistine ritual practices      (via sciencedaily.com)     Original source 

While many aspects of Philistine culture are well-documented, the specifics of Philistine religious practices and deities have long remained shrouded in mystery. A recent study contributes valuable new data to our understanding of the Philistine's ritual practices. The discovery of numerous plants in two temples unearthed at the site unraveled unprecedented insights into Philistine cultic rituals and beliefs -- their temple food ingredients, timing of ceremonies, and plants for temple decoration.

Neanderthals and humans lived side by side in Northern Europe 45,000 years ago      (via sciencedaily.com)     Original source 

Archaeologists have debated whether Neanderthals or modern humans made stone tools that are found at sites across northern Europe and date from about 40,000 years ago. A new excavation at one site in Germany turned up 45,000-year-old bone fragments that, when analyzed for mitochondrial DNA, proved to be from Homo sapiens. This is the earliest evidence that modern humans overlapped with Neanderthals in northwest Europe, thousands of years before Neanderthals went extinct.
