First silicon integrated ECRAM for a practical AI accelerator      (via sciencedaily.com) 

The transformative changes brought by deep learning and artificial intelligence are accompanied by immense costs. For example, OpenAI's ChatGPT algorithm costs at least $100,000 every day to operate. This could be reduced with accelerators, or computer hardware designed to efficiently perform the specific operations of deep learning. However, such a device is only viable if it can be integrated with mainstream silicon-based computing hardware on the material level.

Paper written using ChatGPT demonstrates opportunities and challenges of AI in academia      (via sciencedaily.com) 

In an innovative new study, researchers used a series of prompts and questions to encourage ChatGPT to produce the type of content commonly seen in academic publications. Researchers say in their paper's discussion section -- which was written without the software's influence -- that it demonstrates the new levels of sophistication which AI now offers and also the opportunities and challenges it poses for the academic community.

Genome research: Origin and evolution of vine      (via sciencedaily.com) 

Cultivation and growth of grapevines have strongly influenced European civilizations, but where the grapevine comes from and how it has spread across the globe has been highly disputed so far. In an extensive genome project, researchers have determined its origin and evolution from the wild vine to today's cultivar by analyzing thousands of vine genomes collected along the Silk Road from China to Western Europe.

3D-printed revolving devices can sense how they are moving      (via sciencedaily.com) 

Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ability to sense their angular position, rotation speed, and direction of rotation.

Cyprus's copper deposits created one of the most important trade hubs in the Bronze Age      (via sciencedaily.com) 

The coveted metal copper and a sheltered location turned the Cypriot village of Hala Sultan Tekke into one of the most important trade hubs of the Late Bronze Age. Recent excavations confirm the importance of the Bronze Age city in the first period of international trade in the Mediterranean.

Indigenous Ashaninka DNA helps geneticists write new chapters of pre-colonial history in South America      (via sciencedaily.com) 

Geneticists have written new chapters in the reconstruction of pre-colonial Americas history after using DNA from the indigenous Ashaninka people from Amazonian Peru. They have discovered previously unexpected levels of genetic variation in this group and uncovered a strong hint that these people were involved in a South-to-North migration that led to the transition from an archaic to ceramic culture in the Caribbean islands.

Mix-and-match kit could enable astronauts to build a menagerie of lunar exploration bots      (via sciencedaily.com) 

The Walking Oligomeric Robotic Mobility System, or WORMS, is a reconfigurable, modular, multiagent robotics architecture for extreme lunar terrain mobility. The system could be used to assemble autonomous worm-like parts into larger biomimetic robots that could explore lava tubes, steep slopes, and the moon's permanently shadowed regions.

Lasers and chemistry reveal how ancient pottery was made -- and how an empire functioned      (via sciencedaily.com) 

Peru's first great empire, the Wari, stretched for more than a thousand miles over the Andes Mountains and along the coast from 600-1000 CE. The pottery they left behind gives archaeologists clues as to how the empire functioned. In a new study researchers showed that rather than using 'official' Wari pottery imported from the capital, potters across the empire were creating their own ceramics, decorated to emulate the traditional Wari style. To figure it out, the scientists analyzed the pottery's chemical make-up, with help from laser beams.

Surprising similarities in stone tools of early humans and monkeys      (via sciencedaily.com) 

Researchers have discovered artefacts produced by old world monkeys in Thailand that resemble stone tools, which historically have been identified as intentionally made by early hominins. Until now, sharp-edged stone tools were thought to represent the onset of intentional stone tool production, one of the defining and unique characteristics of hominin evolution. This new study challenges long held beliefs about the origins of intentional tool production in our own lineage.
