Published Invasive rats transform reef fish behavior
(via sciencedaily.com) Scientists have discovered for the first time that invasive rats on tropical islands are affecting the territorial behavior of fish on surrounding coral reefs. The new study shows that the presence of invasive black rats on tropical islands is causing changes in the territorial behavior of the jewel damselfish -- a herbivorous species of tropical reef fish that 'farm' algae in the branches of corals.
Published Effects of highly pathogenic avian influenza on canids investigated
(via sciencedaily.com) Researchers have revealed the effects of high pathogenicity avian influenza virus infection on an Ezo red fox and a Japanese raccoon dog, linking their infection to a recorded die-off of crows.
Published Current Antarctic conservation efforts are insufficient to avoid biodiversity declines, study shows
(via sciencedaily.com) Existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are likely for 65% of the continent's plants and wildlife by the year 2100, according to a new study.
Published Bird diversity increased in severely burned forests of Southern Appalachian mountains
(via sciencedaily.com) A new study found bird diversity increased in North Carolina mountain forest areas severely burned by wildfire in 2016, reinforcing that while wildfire can pose risks to safety and property, it can be beneficial to wildlife. The study results could help forest managers better predict bird responses to wildfire, and manage forests to benefit birds.
Published Words prove their worth as teaching tools for robots
(via sciencedaily.com) What is the best way to teach a robot? Sometimes it may simply be to speak to it clearly. Researchers found that human-language descriptions of tools can accelerate the learning of a simulated robotic arm lifting and using a variety of tools.
Published Palau's Rock Islands harbor heat-resistant corals
(via sciencedaily.com) Original source Ocean warming is driving an increase in the frequency and severity of marine heatwaves, causing untold damage to coral reefs. Tropical corals, which live in symbiosis with tiny single celled algae, are sensitive to high temperatures, and exhibit a stress response called bleaching when the ocean gets too hot. In the last 4 decades, marine heatwaves have caused widespread bleaching, and killed millions of corals. Because of this, a global search is underway for reefs that can withstand the heat stress, survive future warming, and act as sources of heat-tolerant coral larvae to replenish affected areas both naturally and through restoration.
Published The physical intelligence of ant and robot collectives
(via sciencedaily.com) Researchers took inspiration from ants to design a team of relatively simple robots that can work collectively to perform complex tasks using only a few basic parameters.
Published Should we tax robots?
(via sciencedaily.com) A small tax on robots, as well as on trade generally, will help reduce income inequality in the U.S., according to economists.
Published New software based on Artificial Intelligence helps to interpret complex data
(via sciencedaily.com) Experimental data is often not only highly dimensional, but also noisy and full of artefacts. This makes it difficult to interpret the data. Now a team has designed software that uses self-learning neural networks to compress the data in a smart way and reconstruct a low-noise version in the next step. This enables it to recognize correlations that would otherwise not be discernible. The software has now been successfully used in photon diagnostics at the FLASH free electron laser at DESY. But it is suitable for very different applications in science.
Published New winged robot can land like a bird
(via sciencedaily.com) Researchers have developed a method that allows a flapping-wing robot to land autonomously on a horizontal perch using a claw-like mechanism. The innovation could significantly expand the scope of robot-assisted tasks.
Published Ecology: More than the sum of its parts
(via sciencedaily.com) Original source The number of simultaneously acting global change factors has a negative impact on the diversity of plant communities -- regardless of the nature of the factors.
Published Designing better battery electrolytes
(via sciencedaily.com) Scientists give the lay of the land in the quest for electrolytes that could enable revolutionary battery chemistries.
Published Researchers develop wireless, ultrathin 'Skin VR' to provide a vivid, 'personalized' touch experience in the virtual world
(via sciencedaily.com) Enhancing the virtual experience with the touch sensation has become a hot topic, but today's haptic devices remain typically bulky and tangled with wires. Researchers have now developed an advanced wireless haptic interface system, called WeTac, worn on the hand, which has soft, ultrathin soft features, and collects personalized tactile sensation data to provide a vivid touch experience in the metaverse.
Published New robot does 'the worm' when temperature changes
(via sciencedaily.com) A new gelatinous robot that crawls, powered by nothing more than temperature change and clever design, brings 'a kind of intelligence' to the field of soft robotics.
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 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 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 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.
