Published Researchers uncover the secrets of 'plant puberty'
(via sciencedaily.com) Original source Researchers have identified the genetic changes linked to why plants go through a developmental change similar to 'puberty' at different rates, a discovery which could lead to better crop nutrition.
Published Peering into the mind of artificial intelligence to make better antibiotics
(via sciencedaily.com) Original source Artificial intelligence (AI) has exploded in popularity as of late. But just like a human, it's hard to read an AI model's mind. Explainable AI (XAI) could help us do just that by providing justification for a model's decisions. And now, researchers are using XAI to scrutinize predictive AI models more closely, which could help make better antibiotics.
Published Action plan to help patients with lung disease cope with wildfire smoke
(via sciencedaily.com) Original source A multidisciplinary team has developed an action plan to help patients with respiratory diseases mitigate the consequences of poor air quality from wildfires.
Published Researchers develop index to quantify circular bioeconomy
(via sciencedaily.com) Original source As the world faces the challenges of mitigating climate change and providing resources for a growing population, there is increasing focus on developing circular economies for sustainable production. But to evaluate strategies and impacts, it is necessary to have reliable metrics. Researchers have now developed a Circularity Index that provides a comprehensive method to quantify circularity in bioeconomic systems. In a new paper, they outline the method and apply it to two case studies -- a corn/soybean farming operation and the entire U.S. food and agriculture system.
Published Less severe forest fires can reduce intensity of future blazes
(via sciencedaily.com) Original source Low- and moderate-severity forest wildfires can reduce the intensity of future fires, according to new research on 'reburns.'
Published Forest loss intensifies climate change by increasing temperatures and cloud level, which leads to decrease of water
(via sciencedaily.com) Original source Researchers report that deforestation during the last two decades induced a higher warming and cloud level rise than that caused by climate change, which threatens biodiversity and water supply in African montane forests.
Published New insights on how bird flu crosses the species barrier
(via sciencedaily.com) Original source The avian influenza virus needs to mutate to cross the species barrier and to infect and replicate within mammalian cells. Scientists have now deciphered the structure of the avian influenza virus's polymerase when it interacts with a human protein essential for the virus to replicate within the cell. The structure of this replication complex provides important information about the mutations that avian influenza polymerase must undergo to adapt to mammals, including humans. These results can help scientists monitor the evolution and adaptability of bird flu strains, such as H5N1 or H7N9, towards infecting other species.
Published Urban street networks, building density shape severity of floods
(via sciencedaily.com) Original source The design of streets and layout of buildings have an impact on a city's resilience in the face of increasingly severe floods brought on by climate change. Researchers look at buildings and other urban structures as physicists consider elements in complex material systems. With this insight, the researchers have developed a new approach to urban flood modelling and found their results helpful in analyzing city-to-city variations in flood risk globally.
Published Searching old stem cells that stay young forever
(via sciencedaily.com) Original source The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated by evolutionary highly conserved genes.
Published Preservation of organic carbon in the ocean floor
(via sciencedaily.com) Original source The preservation of organic carbon in marine sediments has long been a key question remaining unclear in understanding the long-term carbon cycling on Earth. Recently, scientists have gained new insights into the dynamic cycling of iron-bound organic carbon in subseafloor sediments.
Published Preliminary study shows potential of Manuka honey as a nutraceutical for breast cancer
(via sciencedaily.com) Original source A new study found that Manuka honey could potentially be an alternative, natural option for breast cancer prevention and treatment -- particularly for estrogen receptor (ER)-positive breast cancer, the most common subtype of breast cancer that accounts for about 70-80% of all breast cancer cases.
Published Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia
(via sciencedaily.com) Original source Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers sequenced mitochondrial DNA from archaeological dogs. Their findings suggest a complex social history of dogs during the early colonial period.
Published New twist on synthesis technique promises sustainable manufacturing
(via sciencedaily.com) Original source Researchers developed a new method known as flash-within-flash Joule heating (FWF) that could transform the synthesis of high-quality solid-state materials, offering a cleaner, faster and more sustainable manufacturing process.
Published Nitrogen interventions as a key to better health and robust ecosystems
(via sciencedaily.com) Original source An international research team combined multidisciplinary methods to evaluate how nitrogen interventions could improve air quality and reduce nitrogen deposition. Their study found that interventions, such as improving fuel combustion conditions, increasing agricultural nitrogen use efficiency, and reducing food loss and waste, could significantly lower premature deaths attributed to air pollution, crop losses, and ecosystems risks.
Published Knocking out one key gene leads to autistic traits
(via sciencedaily.com) Original source Hyperactivity, repetitive behavior, and language deficits all appeared in the mice, highlighting an unexpected role the cerebellum seems to play in autism.
Published Scientists discover phenomenon impacting Earth's radiation belts
(via sciencedaily.com) Original source Two scientists discovered a new type of 'whistler,' an electromagnetic wave that carries a substantial amount of lightning energy to the Earth's magnetosphere.
Published Decoding mysterious seismic signals
(via sciencedaily.com) Original source Geophysicists find link between seismic waves called PKP precursors and anomalies in Earth's mantle that are associated with hotspots associated with volcanism on the surface.
Published Scottish and Irish rocks confirmed as rare record of 'snowball Earth'
(via sciencedaily.com) Original source The study found that the Port Askaig Formation, composed of layers of rock up to 1.1 km thick, was likely laid down between 662 to 720 million years ago during the Sturtian glaciation -- the first of two global freezes thought to have triggered the development of complex, multicellular life.
Published It's a rave: Underground acoustics amplify soil health
(via sciencedaily.com) Original source Barely audible to human ears, healthy soils produce a cacophony of sounds in many forms -- a bit like an underground rave concert of bubble pops and clicks. Special recordings made by ecologists show this chaotic mixture of soundscapes can be a measure of the diversity of tiny living animals in the soil, which create sounds as they move and interact with their environment.
Published Exploring options for the sustainable management of phosphorus
(via sciencedaily.com) Original source A new study assessed the feasibility of recovering phosphorus from municipal wastewater as an alternative sustainable source of this non-renewable mineral.
