Contrasting response of rice rhizosphere microbiomes to in situ cadmium-contaminated soil remediation

Understanding the responses of different rhizosphere microbial lineages to soil amendments during in situ remediation of Cd-contaminated soil is of great importance in the assessment of the restoration and crop health. This study demonstrates the distinct responses of rice rhizosphere microbial communities to soil amendment applications, highlighting the interactive associations between microbiomes, which is vital for enhancing our ability to develop effective strategies for sustainable soil management. The researchers' findings appeared December 4, 2023 in Soil Ecology Letters.
A series of studies on the diversities and interactions of rice rhizosphere microbial communities have been conducted by Jiachun Shi's team at the Zhejiang University, and many interesting findings have been obtained. For example, they found that soil pH was the key factor affecting the proportion of available Cd in total Cd during Cd-contaminated soil remediation. The bacterial community was more sensitive to soil amendment-induced changes, and treatments with pig-manure and commercial Mg-Ca-Si conditioner significantly increased the relative abundances of protistan phototrophs. Notably, co-occurrence network analysis revealed that soil amendments increased microbial network complexity and triggered the role of protists, especially for the predatory protists Cercozoa, on microbial trophic interactions. Also, the bacteria community was a more important biotic driver of the protistan community.
In this study, their results show that application of soil amendments immobilized available Cd in soil and altered the microbial communities in the rhizosphere of rice under in situ Cd-contaminated soil remediation. Among three microbial lineages investigated in this study, bacteria communities turned out as the most sensitive microbial group to soil amendments-induced changes in soil properties. Lime and biochar increased the relative abundances of protistan consumers, and pig manure and commercial conditioner significantly promoted the relative abundances of phototrophs. Interestingly, all four amendments enhanced the potential crucial role of protistan taxa Cercozoa in regulating the interactions with microbes. The edaphic properties such as pH, SOM, NO3--N, C/N ratio and bacterial and fungal communities were found to be important abiotic and biotic factors driving protistan community assembly.

Pulmonary malignancy is one of the most frequent and fatal cancers in older patients. Studies have shown that lung cancer patients have a high incidence of lower respiratory tract infections. This is due to the fact that these patients usually have airway obstruction, sticky sputum that is not easy to cough up, destruction of mucosal surfaces, and treatment with radiotherapy and chemotherapy. When most patients are found to have lung cancer, they have already developed distal metastasis and lost the chance of surgery, therefore, they usually choose to be treated with radiotherapy, chemotherapy, and targeted drugs. Radiotherapy and chemotherapy ...

Researchers at the University of Queensland have revealed the crucial role of saturated fatty acids in the brain’s consolidation of memories.
Dr Isaac Akefe from UQ’s Queensland Brain Institute has uncovered the molecular mechanism and identified the genes underlying the memory creation process, opening the door to a potential treatment for neurodegenerative disorders.
“We’ve shown previously that levels of saturated fatty acids increase in the brain during neuronal communication, but we ...

Deep learning has led to great improvements recently on a number of difficult tasks.
In CRYPTO 2019, Gohr innovatively integrated deep learning with differential cryptanalysis, specifically applied to Speck32/64, resulting in developing a neural distinguisher that outperforms the DDT-based distinguisher. Applying differential neural cryptanalysis methods to more cryptographic algorithms is an issue worth studying.
To solve the problems, a research team led by Liu ZHANG published their new research on 15 Dec 2023 in Frontiers of Computer Science co-published by Higher Education Press ...

Ottawa, ON, February 5, 2024 – Twenty-seven percent of individuals who had an emergency department visit for cannabis use developed a new anxiety disorder within three years, according to new research.
Led by researchers at the Bruyère Research Institute, University of Ottawa Department of Family Medicine, The Ottawa Hospital, and ICES, this is the largest study of the relationship between cannabis use and anxiety to date. The study published today in The Lancet’s open access journal eClinical Medicine included over 12 million individuals living in Ontario, Canada, between 2008 and 2019 who had never received a diagnosis or treatment for anxiety. The researchers ...

A Doppler ultrasound that measures the blood flow of small unborn babies can reveal whether or not the placenta is working properly. In case of repeated deviations from these Doppler measurements, additional monitoring of the unborn baby is necessary. These deviations indicate a higher risk of oxygen deficiency and other health problems for the baby. This study by Amsterdam UMC in collaboration with UMC Groningen and 17 other Dutch hospitals is published today in the British Journal of Obstetrics & Gynaecology.
Around 10% of unborn babies are classed as small for ...

A new species of pterosaur from specimens found on the Isle of Skye, Scotland, has been announced by scientists from the Natural History Museum, University of Bristol, University of Leicester, and University of Liverpool.
The new pterosaur is part of the Darwinoptera clade of pterosaurs. Its discovery shows that the clade was considerably more diverse than previously thought, and persisted for more than 25 million years, from the late Early Jurassic to the latest Jurassic. During this period species within the clade spread worldwide.
The discovery underpins a new and more complex model for the early evolution of pterosaurs.
The rarity of Middle Jurassic pterosaur ...

The influence of online vote advice tools designed to help voters discover more about candidates is limited when elections are affected by authoritarianism, a new study shows.
Voting advice applications offer voters nonpartisan information about political parties, candidates, and policy issues.
The research shows they could be an alternative source of information for those interested in learning about politics in democracies, but their use would be limited in authoritarian settings, particularly in the longer term.
In the short-term, and during highly competitive elections with tiny winning margins for candidates ...

A million years ago, the oldest known species to walk upright like a human, the Homo Erectus, had a human-like fascination with crystals. Historians can even pin down the possible reasons – crystals didn’t look like anything around at the time - trees, valleys, mountains. Crystals were a material to ponder, a fascinating diversion for the mind.
To this day, the human preoccupation with the magic of crystals continues to fill the mind’s eye of scientists who have developed ways to use crystals for everything from malaria cures to solar cells and semiconductors, catalysts and optical elements. Over the years crystals have become crucial constituents ...

A multi-disciplinary research team specializing in canine behavior and Artificial Intelligence has developed an AI algorithm that automates the high-stakes process of evaluating potential working dogs’ personalities. They hope to help dog training agencies more quickly and accurately assess which animals are likely to succeed long term in careers such as aiding law enforcement and assisting persons with disabilities. The personality test could also be used for dog-human matchmaking, helping shelters with proper placement, thus reducing the number of animals returned ...

For more than 50 years, the National Hurricane Center has used the Saffir-Simpson Windscale to communicate the risk of property damage; it labels a hurricane on a scale from Category 1 (wind speeds between 74 - 95 mph) to Category 5 (wind speeds of 158 mph or greater).
But as increasing ocean temperatures contribute to ever more intense and destructive hurricanes, climate scientists Michael Wehner of Lawrence Berkeley National Laboratory (Berkeley Lab) and James Kossin of the First Street Foundation wondered whether the ...
