Gene variations for immune and metabolic conditions have persisted in humans for more than 700,000 years      (via sciencedaily.com) 

A new study explores 'balancing selection' by analyzing thousands of modern human genomes alongside ancient hominin groups, such as Neanderthal and Denisovan genomes. The research has 'implications for understanding human diversity, the origin of diseases, and biological trade-offs that may have shaped our evolution,' says evolutionary biologists.

Compact, non-mechanical 3D lidar system could make autonomous driving safer      (via sciencedaily.com) 

A new system represents the first time that the capabilities of conventional beam-scanning lidar systems have been combined with those of a newer 3D approach known as flash lidar. The nonmechanical 3D lidar system is compact enough to fit in the palm of the hand and solves issues of detecting and tracking poorly reflective objects.

Caribou have been using same Arctic calving grounds for 3,000 years      (via sciencedaily.com) 

Caribou have been using the same Arctic calving grounds for more than 3,000 years. Female caribou shed their antlers within days of giving birth, leaving behind a record of their annual travels across Alaska and Canada's Yukon that persists on the cold tundra for hundreds or even thousands of years. Researchers recovered antlers that have sat undisturbed on the arctic tundra since the Bronze Age.

AI-Powered FRIDA robot collaborates with humans to create art      (via sciencedaily.com) 

FRIDA, a robotic arm with a paintbrush taped to it, uses artificial intelligence to collaborate with humans on works of art. Ask FRIDA to paint a picture, and it gets to work putting brush to canvas. The robot uses AI models similar to those powering tools like OpenAI's ChatGPT and DALL-E 2, which generate text or an image, respectively, in response to a prompt. FRIDA simulates how it would paint an image with brush strokes and uses machine learning to evaluate its progress as it works. FRIDA's final products are impressionistic and whimsical. The brushstrokes are bold. They lack the precision sought so often in robotic endeavors. If FRIDA makes a mistake, it riffs on it, incorporating the errant splotch of paint into the end result.

Solving a machine-learning mystery      (via sciencedaily.com) 

Researchers have explained how large language models like GPT-3 are able to learn new tasks without updating their parameters, despite not being trained to perform those tasks. They found that these large language models write smaller linear models inside their hidden layers, which the large models can train to complete a new task using simple learning algorithms.

Interactive cyber-physical human: Generating contact-rich whole-body motions      (via sciencedaily.com) 

Performing human-like motions that involve multiple contacts is challenging for robots. In this regard, a researcher has envisioned an interactive cyber-physical human (iCPH) platform with complementary humanoid (physical twin) and simulation (digital twin) elements. iCPH combines human measurement data, musculoskeletal analysis, and machine learning for data collection and augmentation. As a result, iCPH can understand, predict, and synthesize whole-body contact motions.
