ABSTRACT

The recent discovery of complete ammonia oxidizers (comammox) contradicts the paradigm that chemolithoautotrophic nitrification is always catalyzed by two different microorganisms. However, our knowledge of the survival strategies of comammox in complex ecosystems, such as full-scale wastewater treatment plants (WWTPs), remains limited. Analyses of genomes and in situ transcriptomes of four comammox organisms from two full-scale WWTPs revealed that comammox were active and showed a surprisingly high metabolic versatility. A gene cluster for the utilization of urea and a gene encoding cyanase suggest that comammox may use diverse organic nitrogen compounds in addition to free ammonia as the substrates. The comammox organisms also encoded the genomic potential for multiple alternative energy metabolisms, including respiration with hydrogen, formate, and sulfite as electron donors. Pathways for the biosynthesis and degradation of polyphosphate, glycogen, and polyhydroxyalkanoates as intracellular storage compounds likely help comammox survive unfavorable conditions and facilitate switches between lifestyles in fluctuating environments. One of the comammox strains acquired from the anaerobic tank encoded and transcribed genes involved in homoacetate fermentation or in the utilization of exogenous acetate, both pathways being unexpected in a nitrifying bacterium. Surprisingly, this strain also encoded a respiratory nitrate reductase which has not yet been found in any other Nitrospira genome and might confer a selective advantage to this strain over other Nitrospira strains in anoxic conditions.

IMPORTANCE The discovery of comammox in the genus Nitrospira changes our perception of nitrification. However, genomes of comammox organisms have not been acquired from full-scale WWTPs, and very little is known about their survival strategies and potential metabolisms in complex wastewater treatment systems. Here, four comammox metagenome-assembled genomes and metatranscriptomic data sets were retrieved from two full-scale WWTPs. Their impressive and—among nitrifiers—unsurpassed ecophysiological versatility could make comammox Nitrospira an interesting target for optimizing nitrification in current and future bioreactor configurations.

This paper uses a 3D model for stability assessment of Zhujiabaobao waste dump with ground cracks. The study data were gathered via reconnaissance, geomorphological analysis and laboratory experiment. A 3D finite extended element method model that can consider cracks was then used to calculate the factor of safety (FOS) of the waste dump via the strength reduction technique. The simulation shows the dump to have an FOS of 1.22 and both the position and depth of penetration of cracks in the waste dump have a crucial impact on the stability of the slope. Because the study area is located in a seismically active area, simulation and analysis of the dynamic response of the waste dump under different magnitudes of seismic waves (peak acceleration is 0.05, 0.15, 0.25 and 0.45g) were performed via an explicit dynamic model. The simulation shows that high steps in the slope are particularly responsive to earthquakes. The approach used here for analysing stability under static and dynamic loads is useful for hazard prevention and mitigation.

Nuclear Regulatory Commission keen to allow material to be disposed of by ‘land burial’ – with potentially damaging effects

The federal agency providing oversight of the commercial nuclear sector is attempting to push through a rule change critics say could allow dangerous amounts of radioactive material to be disposed of in places like municipal landfills, with potentially serious consequences to human health and the environment.

Here's an awareness session that seems like the best fit for those of you who are spontaneous shoppers, ever-keen to go on sprees. Donate your old jeans to Dwij that has partnered with a co-working space in the city and see your discarded clothes turn into functional and spunky bags, mats and jewellery.

Founded a year ago with the sole aim of taking care of textile waste, they work with all kinds of fabric that's beyond use. "This workshop will focus on denim, because it's sturdy and discarded frequently when styles change, and not because of wear and tear," says Soumya Kalluri, founder of Dwij.

The products are made at the workshop in Bhandup

After the denim is washed, it will be taken to the workshop where it will be customised according to the 10 to 15 templates they have. Their trained team of six workers, including two women from MHADA colony in Kanjurmarg, bring the product together, instead of it being used to clean up industrial waste and then burnt or buried.

"There is so much textile waste, along with labour abuse. The fashion industry is glamorous, so people tend to look only at the pretty side, not what happens behind the scene. With this talk, we hope to spread awareness about how we are indirectly polluting the environment because until everyone around knows what the problem is, they can't be part of the solution. We want people to think about why they are buying a product the next time they step out to shop," explains Kalluri, a resident of Vikhroli. They will also be giving tips on how you
can make simple products using clothes you want to get rid of at home.

Back in the late 90s, when standards were proprietary and communication protocols complicated, two data formats appeared on the horizon. The first was the extensible markup language, born as an extension of an existing markup language standard (XML), and designed (by an open committee) with the purpose of storing and defining documents and data through the optional use of a schema.  The other, JavaScript Object Notation (JSON), born out of a programming language, was almost the exact opposite – a serialization format with requirements so simple they fit on the back of a business card. XML exploded in application development and communication platforms in the 2000s due in large part to the sheer demand for a human readable, vendor-neutral data format that was easy to read, write and share. As applications and platforms evolved and efficiency grew in priority, APIs evolved to become leaner, and JSON overtook XML as the preferred data interchange format among developers across many technology stacks.

A single factory in Malaysia supplies about 10% of the world’s rare earth oxides, used in everything from cellphones to lasers to missiles. Controversy over the final resting place for the slightly radioactive byproducts has pushed the plant to the brink of closure. Host Meagan Cantwell talks with freelance writer Yao Hua Law about calls to ship the waste back to where it was originally mined in Australia, and how stopping production in Malaysia would mean almost all rare earth production would take place in China.  In another global trade story, host Sarah Crespi talks with freelance writer Sam Kean about close links between the slave trade and early naturalists’ efforts to catalog the world’s flora and fauna. Today, historians and museums are just starting to come to grips with the often-ignored relationships between slavers and scientists. This week’s episode was edited by Podigy.
