Published Researchers develop novel deep learning-based detection system for autonomous vehicles
(via sciencedaily.com) Original source Autonomous vehicles require object detection systems to navigate traffic and avoid obstacles on the road. However, current detection methods often suffer from diminished detection capabilities due to bad weather, unstructured roads, or occlusion. Now, a team of researchers has developed a novel Internet-of-Things-enabled deep learning-based end-to-end 3D object detection system with improved detection capabilities even under unfavorable conditions. This study marks a significant step in autonomous vehicle object detection technology.
Published Broadband buzz: Periodical cicadas' chorus measured with fiber optic cables
(via sciencedaily.com) Original source Through an emerging technology called distributed fiber optic sensing, cables bringing high-speed internet to American households can be used to detect temperature changes, vibrations, and even sound. And periodical cicadas -- the insects that emerge by the billions every 13 or 17 years and make a racket with their mating calls -- are loud enough to be detected. A new study shows how fiber optic sensing could open new pathways for charting populations of these famously ephemeral bugs.
Published The waxy surface protecting plants might hold the key to developing stronger crops
(via sciencedaily.com) Original source Researchers have discovered that the waxy protective barrier around plants might play a role in sending chemical signals to other plants and insects.
Published how far can the wind can carry a plant's seeds? New model
(via sciencedaily.com) Original source Playing an essential foundational role in an ecosystem, plants contribute to the well-being of human health by helping create resources like food and medicine. Therefore, to better understand how plants can maintain resiliency in the face of challenges like climate change, researchers recently developed an innovative mathematical model that can provide fast and reliable predictions of how far wind can carry a plant's seeds.
Published Small marine creatures swimming in plastic chemicals not reproducing
(via sciencedaily.com) Original source Plastic waste in the water might be stopping -- or interrupting -- some shrimp-like creatures from reproducing. In a unique study, the ability of 'shrimp like' creatures to reproduce successfully was found to be compromised by chemicals found in everyday plastics.
Published Twin research indicates that a vegan diet improves cardiovascular health
(via sciencedaily.com) Original source A recent trial of identical twins comparing vegan and omnivore diets found that a vegan diet improves overall cardiovascular health.
Published This 'gross' mixture has big benefits for the study of bacteria
(via sciencedaily.com) Original source Researchers have discovered that growing bacteria on agar mixed with organs is an efficient and effective way to study infectious pathogens.
Published Identifying Australia's most elusive birds
(via sciencedaily.com) Original source Scientists have analyzed more than 3.8 million volunteer hours of birdwatching data to identify Australia's most elusive species.
Published Unknown animals were leaving bird-like footprints in Late Triassic Southern Africa
(via sciencedaily.com) Original source Ancient animals were walking around on bird-like feet over 210 million years ago, according to a new study.
Published Blasts to clear World War II munitions could contaminate the ocean
(via sciencedaily.com) Original source World War II concluded decades ago, but live mines lurking on the ocean floor still pose threats, potentially spewing unexpected geysers or releasing contaminants into the water. Experts conduct controlled explosions to clear underwater munitions, but concerns have arisen over the environmental impacts from these blasts. New results show that the contamination produced by detonation depends on the blast type, with weaker explosions leaving behind more potentially toxic residues.
Published Vulnerability of England's only resident bottlenose dolphins
(via sciencedaily.com) Original source New research has provided a detailed examination of England's bottlenose dolphin population's existence and the challenges it faces from human activities and environmental factors on a daily basis.
Published The venom preceded the stinger: Genomic studies shed light on the origins of bee venom
(via sciencedaily.com) Original source Bees, wasps and ants belong to the Hymenoptera order and inject a whole cocktail of venomous ingredients when they sting. Despite their tremendous ecological and economic importance, little was previously known about the origins of their venom. Through extensive genomic studies, a team of researchers has now discovered that typical venomous components were already present in the earliest ancestors of Hymenoptera and must therefore have evolved before the stingers of bees and other insects. What's more, and contrary to previous assumptions, the gene for the venom melittin is found solely in bees.
Published Landscape dynamics determine the evolution of biodiversity on Earth
(via sciencedaily.com) Original source A landmark study into the geological timescale distribution of sediment and nutrients over 500 million years shows that species biodiversity on Earth is driven by landscape dynamics.
Published Nearly 400,000 new compounds added to open-access materials database
(via sciencedaily.com) Original source New technology often calls for new materials -- and with supercomputers and simulations, researchers don't have to wade through inefficient guesswork to invent them from scratch.
Published Network of robots can successfully monitor pipes using acoustic wave sensors
(via sciencedaily.com) Original source An inspection design method and procedure by which mobile robots can inspect large pipe structures has been demonstrated with the successful inspection of multiple defects on a three-meter long steel pipe using guided acoustic wave sensors.
Published How do you make a robot smarter? Program it to know what it doesn't know
(via sciencedaily.com) Original source Engineers have come up with a new way to teach robots to know when they don't know. The technique involves quantifying the fuzziness of human language and using that measurement to tell robots when to ask for further directions. Telling a robot to pick up a bowl from a table with only one bowl is fairly clear. But telling a robot to pick up a bowl when there are five bowls on the table generates a much higher degree of uncertainty -- and triggers the robot to ask for clarification.
Published Researchers engineer a material that can perform different tasks depending on temperature
(via sciencedaily.com) Original source Researchers report that they have developed a new composite material designed to change behaviors depending on temperature in order to perform specific tasks. These materials are poised to be part of the next generation of autonomous robotics that will interact with the environment.
Published Fish ecologist's research indicates need to conserve iconic migratory snook in Mexico
(via sciencedaily.com) Original source Biologists investigated the snook’s almost 400-mile migration up into the rainforest habitat of the Usumacinta River. They have found that the snook, which connect aquatic food webs and support fisheries, spawn and start their lives in coastal nursery habitats before moving into river habitats that offer an array of food resources.
Published Pioneering research method reveals bluefin tuna's fate
(via sciencedaily.com) Original source The Mediterranean spawning grounds of Bluefin tuna -- the largest tuna and one of the most powerful fish in the sea -- are under threat, due to rising sea temperatures. A pioneering research method to decode bluefin 'otoliths' (a stony tissue found in their ear) has determined the threshold sea temperature at which bluefin thrive to be 28 degrees Celsius.
Published Fish IgM structure sheds light on antibody evolution
(via sciencedaily.com) Original source Researchers have analyzed the antibody Immunoglobulin M in rainbow trout to shed some light on why these proteins may have evolved over time.
