Published Molecular shape-shifting
(via sciencedaily.com) Structures made out of building blocks can shift their shape and autonomously self-organize to a new configuration. The physicists revealed this mechanism which may be used to actively manipulate molecular organization. A seed of the novel desired configuration is sufficient to trigger reorganization. This principle can be applied on to biological building blocks which are constantly recycled to form new structures in living systems.
Published Model shows how intelligent-like behavior can emerge from non-living agents
(via sciencedaily.com) A new model describes how biological or technical systems form complex structures equipped with signal-processing capabilities that allow the systems to respond to stimulus and perform functional tasks without external guidance.
Published Extinct 'monkey lemur' shows similarities to fossil humans
(via sciencedaily.com) Analysis of teeth of extinct lemurs has revealed fascinating clues to the evolution of humans, a new study has found.
Published Bolstering the safety of self-driving cars with a deep learning-based object detection system
(via sciencedaily.com) Self-driving cars need to implement efficient, effective, and accurate detection systems to provide a safe and reliable experience to its users. To this end, an international research team has now developed an end-to-end neural network that, in conjunction with the Internet-of-Things technology, detects object with high accuracy (> 96%) in both 2D and 3D. The new method outperforms the current state-of-the-art methods and the way to new 2D and 3D detection systems for autonomous vehicles.
Published Immune system of modern Papuans shaped by DNA from ancient Denisovans, study finds
(via sciencedaily.com) Modern Papuans' immune system likely evolved with a little help from the Denisovans, a mysterious human ancestor who interbred with ancient humans, according to a new study.
Published How intensive agriculture turned a wild plant into a pervasive weed
(via sciencedaily.com) Agriculture is driving rapid evolutionary change, not just on farms but also in wild species in surrounding landscapes, new research has found.
Published Soft robot detects damage, heals itself
(via sciencedaily.com) Engineers have created a soft robot capable of detecting when and where it was damaged -- and then healing itself on the spot.
Published For 400 years, Indigenous tribes buffered climate's impact on wildfires in the American Southwest
(via sciencedaily.com) Original source Devastating megafires are becoming more common, in part, because the planet is warming. But a new study suggests bringing 'good fire' back to the U.S. and other wildfire fire-prone areas, as Native Americans once did, could potentially blunt the role of climate in triggering today's wildfires.
Published Jawbone may represent earliest presence of humans in Europe
(via sciencedaily.com) For over a century, one of the earliest human fossils ever discovered in Spain has been long considered a Neanderthal. However, new analysis from an international research team dismantles this century-long interpretation, demonstrating that this fossil is not a Neanderthal; rather, it may actually represent the earliest presence of Homo sapiens ever documented in Europe.
Published Researchers use ultrasound waves to move objects hands-free
(via sciencedaily.com) Researchers have discovered a new method to move objects using ultrasound waves, opening the door for using contactless manipulation in industries such as robotics and manufacturing.
Published Checking blood pressure in a heartbeat, using artificial intelligence and a camera
(via sciencedaily.com) Original source Engineers have designed a system to remotely measure blood pressure by filming a person's forehead and extracting cardiac signals using artificial intelligence algorithms.
Published Pulses driven by artificial intelligence tame quantum systems
(via sciencedaily.com) Original source Machine learning drives self-discovery of pulses that stabilize quantum systems in the face of environmental noise.
Published Ancient DNA from medieval Germany tells the origin story of Ashkenazi Jews
(via sciencedaily.com) Extracting ancient DNA from teeth, an international group of scientists peered into the lives of a once-thriving medieval Ashkenazi Jewish community in Erfurt, Germany. The findings show that the Erfurt Jewish community was more genetically diverse than modern day Ashkenazi Jews.
Published Interdisciplinary environmental history: How narratives of the past can meet the challenges of the anthropocene
(via sciencedaily.com) A new article discusses vital methodological issues for humanities-based historical inquiry and argues that the challenges of the Anthropocene demand interdisciplinary research informed by a variety of historical narratives.
Published Human evolution wasn't just the sheet music, but how it was played
(via sciencedaily.com) A team of researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.
Published 'Primordial super-enhancers' provide early snapshot of the mechanisms that allowed for multicellularity
(via sciencedaily.com) A new study has found that organelle-like transcriptional condensates are an ancient and flexible tool used by cells to drive rapid gene expression.
Published 1,700-year-old spider monkey remains discovered in Teotihuacán, Mexico
(via sciencedaily.com) Original source The complete skeletal remains of a spider monkey -- seen as an exotic curiosity in pre-Hispanic Mexico -- grants researchers new evidence regarding social-political ties between two ancient powerhouses: Teotihuacán and Maya Indigenous rulers. The remains of other animals were also discovered, as well as thousands of Maya-style mural fragments and over 14,000 ceramic sherds from a grand feast. These pieces are more than 1,700 years old.
Published Oldest evidence of the controlled use of fire to cook food, researchers report
(via sciencedaily.com) Original source The remains of a huge carp fish mark the earliest signs of cooking by prehistoric human to 780,000 years ago, predating the available data by some 600,000 years, according to researchers.
