Natural symbiosis: How plants and microbes share vital nutrients in fragile ecosystems
Nitrogen is essential for all living organisms, but in many ecosystems it is in short supply. Plants and soil microbes both rely on nitrogen to grow, leading to intense competition below ground. Researchers at The University of Manchester have uncovered how plants and soil microb
Researchers find microplastics in hedgehogs—then trace them back to pet food
Researchers find microplastics in hedgehogs—then trace them back to pet food
When colleagues and I found microplastics in hedgehog droppings, we wanted to know where they were coming from. One answer was surprisingly close to home: pet food.
Symbiotic partner-swapping or long-term fidelity? Partnership success between beetles and
Some insects and microbes develop symbiotic partnerships that become so interdependent they can no longer survive without each other. But how specific are these heritable symbioses? Is it possible for the same species of bacteria to flourish across different species of insect hos

Unique instruments automate sample preparation, quality control for cryo-electron microsco
Cryo-electron microscopy (cryo-EM) can help scientists determine the three-dimensional structure of proteins in unprecedented detail. Jacques Dubochet, former group leader at EMBL, shared the 2017 Nobel Prize in chemistry with Joachim Frank and Richard Henderson for the developme
New biofilm mechanism in Bacillus cereus could reveal vulnerabilities in food poisoning ba
Scientists from the Department of Microbiology at the University of Malaga, who are also members of the Institute of Subtropical and Mediterranean Horticulture "La Mayora" (IHSM), have discovered a previously unknown mechanism that allows the bacterium Bacillus cereus, which is r
Oysters used as living labs reveal unexpected stability in ocean virus populations
Oysters filter seawater for food. In the process, they concentrate a wide variety of microorganisms from their environment—including bacteria and viruses—into a tiny space.

Estudo aponta contaminação em toda a extensão do rio Tietê
Levantamento da SOS Mata Atlântica identificou microplásticos em todos os pontos analisados e 25 tipos de defensivos agrícolas ao longo do curso do rio em São Paulo. O post Estudo aponta contaminação em toda a extensão do rio Tietê apareceu primeiro em Canal Rural.
CleanFinder brings browser-based genome editing analysis to labs without coding
Genome editing lets scientists rewrite DNA, the instruction manual inside every living cell, with a precision that was unthinkable a generation ago. Technologies such as CRISPR have made this almost routine, and its uses now reach far beyond medicine, from engineering hardier cro
Why climate change could make staple crops less nutritious—and how CRISPR may help
Why climate change could make staple crops less nutritious—and how CRISPR may help
At present, more than 700 million people live with caloric hunger, and more than 2 billion suffer from micronutrient deficiencies, known as "hidden hunger." By prioritizing high yield over nutritional quality, global calorie production has increased while exacerbating vitamin and

Researchers develop a new prodrug and localized drug delivery platform for selective treat
A new collaborative study reports the discovery and application of a novel therapeutic strategy to selectively target EGFR and other kinases with controlled release in tumor microenvironments to improve therapeutic efficacy, with promising results. The research is published in Bi

Tiny water droplets transmutate aniline into pyridine in ambient and catalyst-free conditi
Aniline can now be transformed into pyridine without adding any catalysts, oxidants or toxic reagents. In a recent study published in the Journal of the American Chemical Society, researchers achieved skeletal editing, involving the reorganization of the carbon-nitrogen bonds wit
