Published Key nutrients help plants beat the heat
(via sciencedaily.com) Original source Scientists have discovered some of the molecular mechanisms controlling how plants -- including important crops like soybean and rice -- will respond to rising global temperatures, finding higher temperatures make root systems grow faster, but sustaining this increased growth speed depends on high levels of nitrogen and phosphorus in the soil. The discoveries point to the necessity of nitrogen and phosphorus-rich soil to promote crop growth and create nutritious crops, in addition to aiding a mission to create more resilient crops in the face of climate change.
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 Oral nucleoside antiviral is progressing toward future pandemic preparedness
(via sciencedaily.com) Original source Obeldesivir (GS-5245), a novel investigational small molecule oral antiviral, represents a new tool in the ongoing effort to prepare for future pandemics.
Published The embryo assembles itself
(via sciencedaily.com) Original source Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of birds. Interestingly, the mammalian embryo develops similarly. Scientists now introduce a mathematical framework that analyzes self-organization from a single cell to a multicellular organism.
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 Captivating blue-colored ant discovered in India's remote Siang Valley
(via sciencedaily.com) Original source A new species of blue ant was discovered in Yingku village in Arunachal Pradesh, Northeastern India. It was named Paraparatrechina neela, after the word 'neela' which means blue in various Indian languages. Its unique blue coloration makes it stand out among other ant species.
Published Food drove the evolution of giraffes' long neck
(via sciencedaily.com) Original source A study explores body proportions of Masai giraffes, lending insight into why giraffes have such long necks and how this trait might have evolved.
Published How sharks survived a major spike in Earth's temperature
(via sciencedaily.com) Original source The sharks we know today as the open ocean's top predators evolved from stubby bottom dwellers during a dramatic episode of global warming millions of years ago.
Published Paving the way for hydrogen from algae enzymes
(via sciencedaily.com) Original source Under certain conditions, some algae are able to produce hydrogen -- a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present. Researchers have identified how such a cofactor, the so-called hydrogen cluster, is assembled. Specifically, they describe the previously unexplained role of the enzyme HydF, which is involved in the final steps of assembly.
Published Researchers discover 'trojan horse' virus hiding in human parasite
(via sciencedaily.com) Original source An international team has found a new RNA virus that they believe is hitching a ride with a common human parasite. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis disease.
Published Lighting up the brain: What happens when our 'serotonin center' is triggered?
(via sciencedaily.com) Original source Scientists have studied the main source of serotonin in the brain -- the dorsal raphe nucleus (DRN). By studying how activating the brain's 'serotonin center' affects awake animals for the first time, they found that serotonin from the DRN activates brain areas that affect behavior and motivation. Results show that DRN serotonin stimulation causes activation of the cerebral cortex and the basal ganglia, brain areas involved in many cognitive functions.
Published The world's most powerful anti-fungal chemistries cause fungal pathogens to self-destruct
(via sciencedaily.com) Original source Scientists have discovered that the most widely-used class of antifungals in the world cause pathogens to self-destruct. The research could help improve ways to protect food security and human lives.
Published Mediterranean diet tied to one-fifth lower risk of early death in women
(via sciencedaily.com) Original source In a new study that followed more than 25,000 initially healthy U.S. women for up to 25 years, researchers found that participants who had greater Mediterranean diet intake had up to 23% lower risk of all-cause mortality, with benefits for both cancer mortality and cardiovascular mortality.
Published Trout in mine-polluted rivers are genetically 'isolated'
(via sciencedaily.com) Original source Trout living in rivers polluted by metal from old mines across the British Isles are genetically 'isolated' from other trout, new research shows.
Published New coral disease forecasting system
(via sciencedaily.com) Original source Research has led to a new tool for forecasting coral disease that could help conservationists step in at the right times with key interventions. Ecological forecasts are critical tools for conserving and managing marine ecosystems, but few forecasting systems can account for the wide range of ecological complexities in near-real-time.
Published New, modified CRISPR protein can fit inside virus used for gene therapy
(via sciencedaily.com) Original source Researchers have developed a novel version of a key CRISPR gene-editing protein that shows efficient editing activity and is small enough to be packaged within a non-pathogenic virus that can deliver it to target cells.
Published Novel virus identified in zebrafish from the pet trade causes disease in laboratory fish
(via sciencedaily.com) Original source Zebrafish in the pet trade are asymptomatic carriers of previously undescribed microbes, including a novel virus that causes hemorrhaging in infected laboratory fish, researchers report.
Published Scientists develop visual tool to help people group foods based on their levels of processing
(via sciencedaily.com) Original source Scientists studying ultra-processed foods have created a new tool for assessing the rewarding and reinforcing properties of foods that make up 58 percent of calories consumed in the United States. The foods have been linked to a wide range of negative health outcomes.
Published New method makes hydrogen from solar power and agricultural waste
(via sciencedaily.com) Original source Engineers have helped design a new method to make hydrogen gas from water using only solar power and agricultural waste such as manure or husks. The method reduces the energy needed to extract hydrogen from water by 600%, creating new opportunities for sustainable, climate-friendly chemical production.
