Revised dating of the Liujiang skeleton renews understanding of human occupation of China      (via sciencedaily.com)     Original source 

Researchers have provided new age estimates and revised provenance information for the Liujiang human fossils, shedding light on the presence of Homo sapiens in the region. Using advanced dating techniques including U-series dating on human fossils, and radiocarbon and optically stimulated luminescence dating on fossil-bearing sediments, the study revealed new ages ranging from approximately 33,000 to 23,000 years ago. Previously, studies had reported ages of up to 227,000 years of age for the skeleton.

More plants on the menu of ancient hunter-gatherers      (via sciencedaily.com)     Original source 

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.

Scientists develop strong yet reusable adhesive from smart materials      (via sciencedaily.com)     Original source 

Scientists have developed a smart, reusable adhesive more than ten times stronger than a gecko's feet adhesion, pointing the way for development of reusable superglue and grippers capable of holding heavy weights across rough and smooth surfaces. The research team found a way to maximize the adhesion of the smart adhesives by using shape-memory polymers, which can stick and detach easily when needed simply by heating them. This smart adhesive can support extremely heavy weights, opening new possibilities for robotic grippers that allow humans to scale walls effortlessly, or climbing robots that can cling onto ceilings for survey or repair applications.

A shortcut for drug discovery      (via sciencedaily.com)     Original source 

For most human proteins, there are no small molecules known to bind them chemically (so called 'ligands'). Ligands frequently represent important starting points for drug development but this knowledge gap critically hampers the development of novel medicines. Researchers at CeMM, in a collaboration with Pfizer, have now leveraged and scaled a method to measure the binding activity of hundreds of small molecules against thousands of human proteins. This large-scale study revealed tens of thousands of ligand-protein interactions that can now be explored for the development of chemical tools and therapeutics. Moreover, powered by machine learning and artificial intelligence, it allows unbiased predictions of how small molecules interact with all proteins present in living human cells. These groundbreaking results have been published in the journal Science (DOI: 10.1126/science.adk5864), and all generated data and models are freely available for the scientific community.

The Dura-Europos site in modern-day Syria is famous for its exceptional state of preservation. Like Pompeii, this ancient city has yielded many great discoveries, and serves as a window into the world of the ancient Hellenistic, Parthian, and Roman periods. Yet despite the prominence of Dura-Europos in Near Eastern scholarship, there is another city, only some miles down the Euphrates river, that presents a long-neglected opportunity for study.
