Published Non-native plants and animals expanding ranges 100 times faster than native species
(via sciencedaily.com) Original source An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts -- a speed that native species cannot manage without human help.
Published When in drought: Researchers map which parts of the Amazon are most vulnerable to climate change
(via sciencedaily.com) Original source Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.
Published Natural hazards threaten over three thousand species
(via sciencedaily.com) Original source Natural hazards can speed up the extinction process of land animals that have limited distribution and/or small populations. But there is hope to turn the negative development around, says researchers behind new study.
Published New dart launcher may be better way to inject animals with drugs
(via sciencedaily.com) Original source A new type of dart launcher has been developed as a safer and more cost-effective alternative to firearms or air guns to inject animals with drugs or tracking chips.
Published Marine heatwaves devastate red gorgonians in the Medes Islands
(via sciencedaily.com) Original source The increase in the frequency and intensity of marine heatwaves in recent decades is one of the effects of global climate change. A study shows that the extreme heatwave of 2022 caused an 'unprecedented' increase in mortality of the red gorgonian Paramuricea clavata, affecting 70% of the colonies located in the Montgr Natural Park, the Medes Islands and the Baix Ter. According to the researchers, these results are 'alarming and threaten the viability' of this species of great value for the biodiversity of benthic ecosystems, since it is considered to be an inhabitant-forming species.
Published Pacific coast gray whales have gotten 13% shorter in the past 20-30 years, Oregon State study finds
(via sciencedaily.com) Original source Gray whales that spend their summers feeding in the shallow waters off the Pacific Northwest coast have undergone a significant decline in body length since around the year 2000, a new study found.
Published A 'liquid battery' advance
(via sciencedaily.com) Original source A team aims to improve options for renewable energy storage through work on an emerging technology -- liquids for hydrogen storage.
Published Humans are the elephant in the room where conservation is debated
(via sciencedaily.com) Original source Studies working to map conservation historically have left humans out of the equation. This study proposes ways to build in the outsized footprint created by people in wild places.
Published Algae offer real potential as a renewable electricity source
(via sciencedaily.com) Original source The need to transition away from fossil fuels to more sustainable energy production is critical. That's why a team of researchers is looking at a potential power source that not only produces no carbon emissions but removes carbon as it works: algae.
Published Semiconductor doping and electronic devices: Heating gallium nitride and magnesium forms superlattice
(via sciencedaily.com) Original source A study revealed that a simple thermal reaction of gallium nitride with metallic magnesium results in the formation of a distinctive superlattice structure. This represents the first time researchers have identified the insertion of 2D metal layers into a bulk semiconductor. By carefully observing materials through various cutting-edge characterization techniques, the researchers uncovered new insights into the process of semiconductor doping and elastic strain engineering.
Published Discovery highlights 'critical oversight' in perceived security of wireless networks
(via sciencedaily.com) Original source A research team has uncovered an eavesdropping security vulnerability in high-frequency and high-speed wireless backhaul links, widely employed in critical applications such as 5G wireless cell phone signals and low-latency financial trading on Wall Street.
Published US public opinion on social media is warming to nuclear energy, but concerns remain
(via sciencedaily.com) Original source The U.S. public displays more positive than negative sentiment toward nuclear energy but concerns remain about waste, cost and safety, according to an analysis of 300,000 posts on social media.
Published Accelerating the R&D of wearable tech: Combining collaborative robotics, AI
(via sciencedaily.com) Original source Engineers have developed a model that combines machine learning and collaborative robotics to accelerate the design of aerogel materials used in wearable heating applications.
Published Rocky shores of Pacific Northwest show low resilience to changes in climate
(via sciencedaily.com) Original source A 15-year period ending in 2020 that included a marine heat wave and a sea star wasting disease epidemic saw major changes in the groups of organisms that live along the rocky shores of the Pacific Northwest.
Published Some countries could meet their total electricity needs from floating solar panels
(via sciencedaily.com) Original source Floating solar photovoltaic panels could supply all the electricity needs of some countries, new research has shown. The researchers calculated the daily electrical output for floating photovoltaics (FPV) on nearly 68,000 lakes and reservoirs around the world, using available climate data for each location.
Published Mapping the seafloor sediment superhighway
(via sciencedaily.com) Original source A new scientific model is giving researchers an unprecedented, global look at the activities of clams, worms, and other invertebrate animals that burrow at the bottom of the ocean.
Published Urgent need for action now for increasing threat from invasive alien species
(via sciencedaily.com) Original source Urgent action now is needed to tackle the major and growing global issue of invasive alien species, says a team of 88 experts from 47 countries. The paper follows the (IPBES) thematic assessment report on invasive alien species and their control. The experts say co-developing management actions with multiple stakeholders including government and private sector stakeholders, and Indigenous Peoples and local communities will be critical to achieving success in addressing biological invasions.
Published Enhancing nanofibrous acoustic energy harvesters with artificial intelligence
(via sciencedaily.com) Original source Scientists have employed artificial intelligence techniques to improve the design and production of nanofibers used in wearable nanofiber acoustic energy harvesters (NAEH). These acoustic devices capture sound energy from the environment and convert it into electrical energy, which can then be applied in useful devices, such as hearing aids.
Published Researchers call for return of Sumas Lake following devastating 2021 floods
(via sciencedaily.com) Original source A new proposal has emerged in response to the November 2021 floods that swept Sumas Prairie in the Fraser Valley, British Columbia, causing mass evacuations and millions in damages. Instead of rebuilding the dykes to manage water flows and prevent future floods, scientists, along with members of the Sumas First Nation and other research partners, suggest an alternative: let Sumas Lake, which was drained in the early 1920s and converted into the farmland known as Sumas Prairie, return to its natural state. This can be done by buying out properties on the lakebed -- a solution that is projected to cost around $1 billion, less than half of the estimated $2.4 billion cost of repairing the dykes and installing a new pump station.
Published Overcoming barriers to heat pump adoption in cold climates and avoiding the 'energy poverty trap'
(via sciencedaily.com) Original source Converting home heating systems from natural gas furnaces to electric heat pumps is seen as a way to address climate change by reducing greenhouse gas emissions.
