Published Researchers develop new, automated, powerful diagnostic tool for drug detection
(via sciencedaily.com) Biomedical engineers present a robust new method for accurately measuring and identifying eight antidepressants most commonly prescribed to women.
Published 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.
Published Bite this! Mosquito feeding chamber uses fake skin, real blood
(via sciencedaily.com) Bioengineers and experts in tropical medicine have invented a new way of studying mosquito feeding behavior using technology instead of live volunteers. Their open-source design combines automated cameras, artificial intelligence and blood-infused, 3D-printed 'synthetic skin.'
Published Reducing pesticide pollution and the intensity of harvesting can increase crop yield and contribute to climate change mitigation
(via sciencedaily.com) Researchers have found that carbon sequestration and plant resilience as well as forage pasture yield can be increased through key adjustments in agricultural management. The results provide a roadmap for reducing pesticide loads in soils and the first steps towards increasing climate change mitigation while improving crop yield in grasslands.
Published Licorice leaf extract is a promising plant protectant for conventional and organic agriculture
(via sciencedaily.com) Original source A study reveals that licorice leaf extract is a potent bactericide and fungicide that can be used in conventional and organic agriculture.
Published Engineers devise a modular system to produce efficient, scalable aquabots
(via sciencedaily.com) Researchers developed a new approach to building deformable underwater robots, using simple repeating substructures. The team demonstrated the new system in two different example configurations, one like an eel and the other a wing-like hydrofoil.
Published Long-term restoration of a biodiversity hotspot hinges on getting seeds to the right place at the right time
(via sciencedaily.com) New research shows that degraded savanna ecosystems can reap lasting benefits from a single seeding of native understory plants. Once a diverse understory of savanna plants became established, its long-term persistence was relatively unaffected by environmental factors -- with one exception. Higher temperatures during the height of the growing season were associated with poorer long-term survival among some species, indicating one threat posed by a warming climate.
Published Pacific Northwest heat dome tree damage more about temperature than drought, scientists say
(via sciencedaily.com) Original source Widespread tree scorch in the Pacific Northwest that became visible shortly after multiple days of record-setting, triple-digit temperatures in June 2021 was more attributable to heat than to drought conditions, researchers say.
Published 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.
Published Evolution of wheat spikes since the Neolithic revolution
(via sciencedaily.com) Original source Around 12,000 years ago, the Neolithic revolution radically changed the economy, diet and structure of the first human societies in the Fertile Crescent of the Near East. With the beginning of the cultivation of cereals -- such as wheat and barley -- and the domestication of animals, the first cities emerged in a new social context marked by a productive economy. Now, a study analyses the evolution of wheat spikes since its cultivation began by the inhabitants of ancient Mesopotamia -- the cradle of agriculture -- between the Tigris and the Euphrates.
Published Robot: I'm sorry. Human: I don't care anymore!
(via sciencedaily.com) Humans are less forgiving of robots after multiple mistakes -- and the trust is difficult to get back, according to a new study.
Published Forest trees find a new watery 'sweet spot' when CO2 is high
(via sciencedaily.com) Original source Trees living in conditions where the carbon dioxide (CO2) has been artificially elevated are likely to become more efficient in conserving water.
Published Climate change may cut US forest inventory by a fifth this century
(via sciencedaily.com) Original source A study found that under more severe climate warming scenarios, the inventory of trees used for timber in the continental United States could decline by as much as 23% by 2100. The largest inventory losses would occur in two of the leading timber regions in the U.S., which are both in the South.
Published Contributing to the utilization of big data! Developing new data learning methods for artificial intelligence
(via sciencedaily.com) A research group has developed a new learning method for artificial intelligence that combines classification performance for data with multiple labels with the ability to learn continually from data. Numerical experiments on real-world multi-label data indicate that the new method outperforms conventional approaches. The simplicity of this algorithm makes it easy to integrate it with other algorithms to devise new ones.
Published Over 4% of summer mortality in European cities is attributable to urban heat islands
(via sciencedaily.com) Original source Over four percent of deaths in cities during the summer months are due to urban heat islands, and one third of these deaths could be prevented by reaching a tree cover of 30%, according to a modelling study. The study results, obtained with data from 93 European cities, highlight the substantial benefits of planting more trees in cities to attenuate the impact of climate change.
Published Understanding plants can boost wildland-fire modeling in uncertain future
(via sciencedaily.com) A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.
Published Legged robots need more testing before real-world use
(via sciencedaily.com) When it comes to the 'evolution' of mobile robots, it may be a long time before legged robots are able to safely interact in the real world, according to a new study.
Published Autonomous steering system keeps human drivers engaged
(via sciencedaily.com) Researchers have developed an automated driving system based on the concept of 'collaborative steering', which aims to increase transportation safety, efficiency, and comfort by encouraging active interaction between autonomous vehicles and their human drivers.
Published A fairy-like robot flies by the power of wind and light
(via sciencedaily.com) The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?
Published Characterization of an emergent plant virus
(via sciencedaily.com) High throughput sequencing (HTS) data is set to improve our knowledge of Physostegia chlorotic mottle virus biology, epidemiology, and genetic diversity.
