To craft early tools, ancient human relatives transported stones over long distances 600,000 years earlier than previously thought

Smithsonian
Peer-Reviewed Publication

In southwestern Kenya more than 2.6 million years ago, ancient humans wielded an array of stone tools—known collectively as the Oldowan toolkit—to pound plant material and carve up large prey such as hippopotamuses. These durable and versatile tools were crafted from special stone materials collected up to eight miles away, according to new research led by scientists at the Smithsonian’s National Museum of Natural History, Cleveland Museum of Natural History and Queens College. Their findings, published Aug. 15 in the journal Science Advances, push back the earliest known evidence of ancient humans transporting resources over long distances by some 600,000 years.

Caught in a social media echo chamber? AI can help you out, new study shows

Binghamton University
Reports and Proceedings

Thanks to AI technologies, the spread of mass-produced contextually relevant articles and comment-laden social media posts has become so commonplace that it can appear as though it’s coming from different information sources. The resulting “echo chamber” effect could reinforce a person’s existing perspectives, regardless of whether that information is accurate.

A new study involving Binghamton University, State University of New York researchers offers a promising solution: developing an AI system to map out interactions between content and algorithms on digital platforms to reduce the spread of potentially harmful or misleading content.

New guidance puts communities at the heart of research

University of the Witwatersrand
Peer-Reviewed Publication

Much previous work in the social sciences has involved researchers – often but not always from the Global North – collecting data from rural communities in the Global South on a wide range of topics from public health to education, agriculture and climate change. Such ‘helicopter’ research is not good practice as it often involves an asymmetry of power and knowledge that invariably disadvantages local communities. So how can research be made more equitable? This is the topic of an analysis undertaken by Jasper Knight from the Wits School of Geography, Archaeology and Environmental Studies, who is also chair of the University’s Non-Medical Ethics Committee, in a new research study published in the International Journal of Qualitative Methods.

A Mount Sinai-Led team creates model for understanding how the brain’s decision-making is impacted in psychiatric disorders

Peer-Reviewed Publication

Scientists from the Icahn School of Medicine at Mount Sinai, working in collaboration with a team from the University of Texas at El Paso, have developed a novel computational framework for understanding how a region of the brain known as the striatum is involved in the everyday decisions we make and, importantly, how it might factor into impaired decision-making by individuals with psychiatric disorders like post-traumatic stress disorder and substance use disorder.
