Microbes in dental plaque look more like relatives in soil than those on the tongue
From the perspective of A. Murat Eren, Ph.D., the mouth is the perfect place to study microbial communities. "Not only is it the beginning of the GI tract, but it's also a very special and small environment that's microbially diverse enough that we c.....»»
Pore structure characteristics found to influence carbon mineralization under conservation tillage
Soil aggregates are the basic units of soil structure and serve as a reservoir for soil carbon, playing a crucial role in the carbon cycle of ecosystems. The pore characteristics of soil aggregates influence the mineralization of soil organic carbon......»»
Neutrons illuminate environmental and biological mysteries
Neutron techniques have long been valued in various scientific fields for their ability to penetrate materials without altering their structure. However, their use in environmental and biological sciences has been limited. Complex systems like soil-w.....»»
Mining the microbiome: Uncovering new antibiotics inside the human gut
The average human gut contains roughly 100 trillion microbes, many of which are constantly competing for limited resources. "It's such a harsh environment," says César de la Fuente, Presidential Assistant Professor in Bioengineering and in Chemical.....»»
Crackles, clicks and pops—now we can monitor the "heartbeat" of soil
Healthy soil is teeming with life. An astonishing 59% of Earth's species live in soil. They play crucial roles in maintaining soil health and, by extension, the health of our planet......»»
New research shows agricultural impacts on soil microbiome and fungal communities
New research from Smithsonian's Bird Friendly Coffee program highlights a type of biodiversity that often gets overlooked: soil bacteria and fungal communities. For over twenty years, Smithsonian research has shown that coffee farms with shade trees.....»»
Soundscape study shows how underground acoustics can amplify soil health
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......»»
Surprise finding in study of environmental bacteria could advance search for better antibiotics
In what they labeled a "surprising" finding, Johns Hopkins Medicine researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the germ's shape. Because the integrity of a bacterial.....»»
Revealing the mysteries within microbial genomes with a new high-throughput approach
A new technique developed at Lawrence Berkeley National Laboratory (Berkeley Lab) will make it much easier for researchers to discover the traits or activities encoded by genes of unknown function in microbes, a key step toward understanding the role.....»»
Rising mercury pollution in soil could be related to climate change, study suggests
In 2017, the Minamata Convention on Mercury went into effect, designed to help curb mercury emissions and limit exposure across the globe. However, a new study of mercury levels in soil suggests that the treaty's provisions might not be enough. A stu.....»»
High nitrogen input promotes the redistribution of new organic carbon to deeper soil layers
Exogenous reactive nitrogen input has a profound effect on the carbon cycle of terrestrial ecosystems. Most current research on soil organic carbon (SOC) dynamics in relation to nitrogen input has focused predominantly on the surface soil layers. How.....»»
Unlocking the secrets of salt stress tolerance in wild tomatoes
As our climate changes and soil salinity increases in many agricultural areas, finding crops that can thrive in these challenging conditions is crucial. Cultivated tomatoes, while delicious, often struggle in salty soils. Their wild cousins, however,.....»»
Microbes conquer the next extreme environment: Your microwave
Since the industrial revolution, microbes have successfully colonized one novel type of habitat after another: for example, marine oil spills, plastic floating in the oceans, industrial brownfields, and even the interior of the International Space St.....»»
Using dental growth rings scientists reveal differences in growth patterns between ancient and modern mammals
A study published in Science Advances reveals how early mammals grew and developed during their pivotal Jurassic radiation. Using a technique called synchrotron X-ray tomography to image growth rings in fossilized tooth roots, the researchers were ab.....»»
Chang"e 6 brought rocks from the far side of the moon back to Earth—what this sample could hold
China achieved a historic feat by bringing back the first-ever sample from the lunar far side in June 2024. It's moon lander, Chang'e 6, used a robotic scoop and drill to collect approximately 5 pounds (2 kilograms) of rocks and soil. These samples c.....»»
Biotech potential set to soar with the help of digital technology
Microbes and fungi have long been nature's helpers in producing fine food, drinks and medicine, but new digital technologies could unlock far greater potential for the European biotech sector......»»
Nanomaterials may enhance plant tolerance to high soil salt levels
Soil salt concentrations above the optimal threshold for plant growth can threaten global food security by compromising agricultural productivity and crop quality. An analysis published in Physiologia Plantarum has examined the potential of nanomater.....»»
Ancient poppy seeds and willow wood offer clues to the Greenland ice sheet"s last meltdown
As we focused our microscope on the soil sample for the first time, bits of organic material came into view: a tiny poppy seed, the compound eye of an insect, broken willow twigs and spikemoss spores. Dark-colored spheres produced by soil fungi domin.....»»
Researchers use vibrations from traffic to measure underground soil moisture
Caltech researchers have developed a new method to measure soil moisture in the shallow subterranean region between the surface and underground aquifers. This region, called the vadose zone, is crucial for plants and crops to obtain water through the.....»»
More microbes found that break down the carbon-fluorine bonds found in some unsaturated PFAS
A team of chemical and environmental engineers at the University of California Riverside, working with colleagues from the University of California Los Angeles, has found a class of microbes that consume PFAS in the environment and sever some of the.....»»
