Published Breathing is going to get tougher
(via sciencedaily.com) Not all pollution comes from people. When global temperatures increase by 4 degrees Celsius, harmful plant emissions and dust will also increase by as much as 14 percent, according to new research.
Published Certain frogs more sensitive to climate change, not protected
(via sciencedaily.com) Amphibians worldwide are affected by climate change and potentially one of the most threatened. Biologists found that some species of amphibians are more likely to be sensitive to climate change because they are not protected by state or federal regulations. The team determined that approximately 11 percent of anuran species are sensitive to climate change, but are not currently listed as at-risk either at the state, federal, or international levels.
Published The rediscovery of an ethereal fairy lantern brightly illuminates their mysterious past
(via sciencedaily.com) After more than 30 years, botanists have rediscovered Thismia kobensis, a type of mysterious-looking rare plant commonly referred to as 'fairy lanterns'. Thismia kobensis was presumed extinct and the surprise rediscovery of this Japanese variety has illuminated hidden aspects of fairy lanterns that have puzzled and fascinated botanists for centuries.
Published Reaching like an octopus: A biology-inspired model opens the door to soft robot control
(via sciencedaily.com) Octopus arms coordinate nearly infinite degrees of freedom to perform complex movements such as reaching, grasping, fetching, crawling, and swimming. How these animals achieve such a wide range of activities remains a source of mystery, amazement, and inspiration. Part of the challenge comes from the intricate organization and biomechanics of the internal muscles.
Published New study reveals biodiversity loss drove ecological collapse after the 'Great Dying'
(via sciencedaily.com) By exploring the stability and collapse of marine ecosystems during the Permian-Triassic mass extinction, researchers gain insights into modern biodiversity crisis.
Published Insect bite marks show first fossil evidence for plants' leaves folding up at night
(via sciencedaily.com) Plants can move in ways that might surprise you. Some of them even show 'sleep movements,' folding or raising their leaves each night before opening them again the next day. Now, researchers offer convincing evidence for these nightly movements, also known as foliar nyctinasty, in fossil plants that lived more than 250 million years ago.
Published Marine heatwaves decimate sea urchins, molluscs and more at Rottnest
(via sciencedaily.com) Researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.
Published Scientists unlock key to drought-resistant wheat plants with longer roots
(via sciencedaily.com) Growing wheat in drought conditions may be easier in the future. Researchers found the right number of copies of a specific group of genes can stimulate longer root growth, enabling wheat plants to pull water from deeper supplies.
Published Effort to help pollinators shows successes, limitations
(via sciencedaily.com) A three-year effort to conserve bee populations by introducing pollinator habitat in North Carolina agricultural areas showed some positive effects, as bee abundance and diversity increased in the studied areas. But results of a study examining the program's effectiveness also showed that the quality of the habitat played a key role in these positive effects, and that habitat quality could be impacted by the way the areas are maintained over time.
Published Malaria infection harms wild African apes
(via sciencedaily.com) Scientists conducted a study that reveals the first evidence of harm caused by malaria infection among wild African apes. They discovered that bonobo populations differ in a key immune trait depending on the presence of malaria infection. Infected populations have a higher frequency of an immune variant that protects against developing severe disease, a pattern that mirrors what is observed among human populations.
Published MoBIE enables modern microscopy with massive data sets
(via sciencedaily.com) High-resolution microscopy techniques, for example electron microscopy or super-resolution microscopy, produce huge amounts of data. The visualization, analysis and dissemination of such large imaging data sets poses significant challenges. Now, these tasks can be carried out using MoBIE, which stands for Multimodal Big Image Data Exploration, a new user-friendly, freely available tool. This means that researchers such as biologists, who rely on high-resolution microscopy techniques, can incorporate multiple data sets to study the processes of life at the very smallest scales.
Published A labyrinth lake provides surprising benefits for an endangered seal
(via sciencedaily.com) The endangered Saimaa ringed seal is an Ice Age relict living in the highly labyrinthine Lake Saimaa, Finland. The newly published work shows that although individual seals have greatly reduced genetic variation, the loss of variation has been complementary, preserving the adaptive potential of the whole population.
Published Urban ponds require attention to ensure biodiversity
(via sciencedaily.com) New research suggests aquatic plants can be utilized as a tool to enhance the co-existence between aquatic invertebrates and their fish predators in urban ponds.
Published Theory can sort order from chaos in complex quantum systems
(via sciencedaily.com) Theoretical chemists have developed a theory that can predict the threshold at which quantum dynamics switches from 'orderly' to 'random,' as shown through research using large-scale computations on photosynthesis models.
Published Digital markers near-perfect for predicting dementia in older drivers
(via sciencedaily.com) Using ensemble learning techniques and longitudinal data from a large naturalistic driving study, researchers have developed a novel, interpretable and highly accurate algorithm for predicting mild cognitive impairment and dementia in older drivers. Digital markers refer to variables generated from data captured through recording devices in the real-world setting. These data could be processed to measure driving behavior, performance and tempo-spatial pattern in exceptional detail.
Published Research team creates statistical model to predict COVID-19 resistance
(via sciencedaily.com) Researchers have created and preliminarily tested what they believe may be one of the first models for predicting who has the highest probability of being resistant to COVID-19 in spite of exposure to SARS-CoV-2, the virus that causes it.
Published Sea stars able to consume kelp-eating urchins fast enough to protect kelp forests, research shows
(via sciencedaily.com) Researchers have provided the first experimental evidence that a species of endangered sea star protects kelp forests along North America's Pacific Coast by preying on substantial numbers of kelp-eating urchins.
Published As sea ice declines in the Arctic, bowhead whales are adjusting their migration patterns
(via sciencedaily.com) As sea ice declines in the Arctic, bowhead whales are staying north of the Bering Strait more frequently, a shift that could affect the long-term health of the bowhead population and impact the Indigenous communities that rely on the whales, a new study shows.
Published Researchers put plant protein mechanism into bacteria to help move forward 50 years of effort
(via sciencedaily.com) Researchers have added components of plant chloroplasts to bacteria. This feat, 50 years in the making, allows them to analyze the proteins in greater detail in order to improve Rubisco, and eventually photosynthesis.
Published Climate 'spiral' threatens land carbon stores
(via sciencedaily.com) The world's forests are losing their ability to absorb carbon due to increasingly 'unstable' conditions caused by humans, a landmark study has found.
