Integrative genomics reveals shared and stress-specific adaptive pathways underlying acidic soil-associated metal toxicity in rice
Soil acidity-associated toxicities of aluminum (Al), cadmium (Cd), and manganese (Mn) severely constrain rice productivity in upland ecosystems. To investigate the genomic basis of adaptation to acidic soil-related metal stress, we conducted an integrated meta-QTL (M-QTL) and functional genomics analysis in rice. Meta-analysis of 681 QTLs and MTAs from 53 QTL mapping and GWAS studies identified 79 robust M-QTLs, including ten overlapping regions associated with Al-, Cd-, and Mn-responsive...
Rovers, regolith, robots: The blueprint for the moon
Rovers, regolith, robots: The blueprint for the moon Lisa Lock Scientific Editor Robert Egan Associate Editor The "soil" blanketing the moon's surface isn't actually soil. It's a fine, lethal, abrasive powder of shattered rock and jagged glass that shreds gaskets, chews through seals, and hangs in an airless environment blasted by unfiltered radiation and temperature swings that can warp steel. Scientists call it lunar regolith.
Biopolymer-based hydrogel formulations for improved seed coating performance
Biopolymer-based hydrogel formulations for improved seed coating performance Lisa Lock Scientific Editor Robert Egan Associate Editor As climate change, soil degradation, and water scarcity place growing pressure on agriculture, scientists are looking for new ways to help crops germinate and grow more efficiently while reducing environmental impact. A new study involving researchers from Nazarbayev University's National Laboratory Astana published in Scientific Reports proposes a promising...
Resident soil microbial diversity and urea amendment legacy interact to shape the composition and expression of a surface film-forming soil inoculant
Soil microbial inoculants have the potential to improve crop yield, enhance agricultural sustainability, and support soil restoration, but they often display unpredictable in-field performance across varied soil conditions. Cyanobacteria-dominated soil surface consortia (SSCs) offer a tractable model for studying inoculant-soil interactions because their visible surface growth enables direct observation and sampling after application. Here, we introduced the SSC "DG1," dominated by the...
Organic foods are not healthier or pesticide free
Organic foods are not healthier...or pesticide free. Organic farming is a marketing ploy that exploits the appeal to nature fallacy As a biomedical scientist, it has never failed to annoy me that the term ‘organic’ has been co-opted to spread misinformation. Before we get into the topic as it relates to foods (and other consumer products), I just want to emphasize that the term organic in chemistry has a VERY different meaning.
Scientists baked sourdough using 5,300-year-old yeast from a frozen mummy
The microscopic yeast that could survive in association with a 5,300-year-old body feels unlikely, almost speculative. Yet the frozen remains of Ötzi, the Copper Age “Iceman” preserved in the Alps and housed in a controlled museum chamber in northern Italy, have provided scientists with an unexpected testing ground for that possibility. Over decades of study, attention gradually shifted beyond bones, tools, and clothing to the invisible biological traces embedded in and around the mummy itself.
Laser 'origami' could help astronauts build structures on the moon
Laser 'origami' could help astronauts build structures on the moon Lisa Lock Scientific Editor Robert Egan Associate Editor University of Florida researchers are exploring how lasers could help astronauts build structures on the moon using materials already available there, including lunar soil transformed into glass. The work, led by Victoria M. Miller, Ph.D., an associate professor in the Herbert Wertheim College of Engineering and researcher with the UF Astraeus Space Institute, recently...
Rainfall near 700 mm marks turning point in ecosystem nitrogen retention
Rainfall near 700 mm marks turning point in ecosystem nitrogen retention Stephanie Baum Scientific Editor Andrew Zinin Lead Editor In a study published in Nature Geoscience, a research team led by Prof. Liu Lingli from the Institute of Botany of the Chinese Academy of Sciences (IBCAS) has identified a mean annual precipitation (MAP) threshold of approximately 700 mm, beyond which the dominant controls on ecosystem nitrogen retention shift. Researchers used naturally occurring soil nitrogen...
Genetic code expansion enables plant-directed control of bacterial activity
Programmable control of microbial gene expression by plant hosts could enable a new generation of precision agricultural biotechnology. Here, using O-methyl-L-tyrosine (OMY) as a model compound, we establish non-standard amino acids (nsAA) as a platform for plant-based control of associated microbial activity. We use genetic code expansion to engineer OMY-dependent control of protein synthesis in the soil bacterium Bacillus subtilis.
Arctic river deltas face rising climate pressure while holding vast frozen carbon reserves
Arctic river deltas face rising climate pressure while holding vast frozen carbon reserves Gaby Clark Scientific Editor Robert Egan Associate Editor Many rivers flow into the Arctic Ocean north of the Arctic Circle—including the Lena in Siberia and the Mackenzie River in Canada. The deltas of these large and small rivers store large amounts of carbon, which is bound there in frozen soils and sediments.
