Born from the COVID-19 pandemic, a viral-agnostic approach blends sequencing research and public health to get ahead of bird flu transmission.

The body of a 52-year-old man was discovered in his Toa Payoh flat last Sunday (Nov 10), several days after his death. The police told AsiaOne they were alerted to the case at 11.15am on Sunday, where they pronounced the man dead at the scene. It is not known when he died.  The man, Bai Zongren (transliteration), had been living alone in his unit at Block 157 Toa Payoh Lorong 1 for several years after divorcing his wife, according to a neighbour who spoke to Shin Min Daily News. He also had a daughter, who moved out with his ex-wife after they split.  The neighbour, who did not want to be named, added that Bai would occasionally get visits from relatives. "His mother used to live on the fifth floor, but she died a few years ago."  The neighbour told Shin Min that she was unaware of Bai's death when she passed by his unit several days ago. As Bai's door was locked, she assumed the flat was empty.  When she passed by his unit again on Saturday, she detected a foul smell but thought that it was from wastewater. She said she only found out about his death when she saw the police at his door.

Aquacycl used bacteria to clean up a wastewater stream and generate enough electricity to run the system and produce clean water.

Treatment systems must demonstrate robust performance while handling both varying volumes and changing wastewater compositions.

Hydraulic fracturing has a low risk for inducing earthquakes that can be felt by people, but underground injection of wastewater produced by hydraulic fracturing and other energy technologies has a higher risk of causing such earthquakes, says a new report from the National Research Council.

Throughout the COVID-19 pandemic, wastewater surveillance has provided advance indications of community-level outbreaks, sometimes weeks before other indicators. A new report says that wastewater surveillance is worthy of investment and outlines a vision for the future of a national system.

designing a wastewater system requires careful consideration of a range of factors to ensure efficient and compliant operation.

The Orange County Sanitation District in Huntington Beach, California provides wastewater collection, treatment, and disposal services for approximately 2.6 million people. They had a combination of loud industrial equipment, cavernous space, and highly reflective surfaces creating an acoustic nightmare.

Public health officials maintain the risk of H5N1 bird flu infection remains low. They are searching for the source.

Wastewater contains nutrients that can overfeed algae, leading to harmful algal blooms and pollution issues in the ocean and other waterways. A new study by researchers at Penn State tracked how these nutrients migrate from disposal sites in the Florida Keys, and the results have already informed wastewater practices in the region.

State agencies will begin accepting applications to loan or grant money for drinking water and wastewater system improvements around the state, with capacity for historic levels of investment in water infrastructure from the federal Bipartisan Infrastructure Law and the state Clean Water Trust, created in 2021.

State government agencies, county and municipal governments, and conservation districts can now submit proposals to the Delaware Department of Natural Resources and Environmental Control and the Delaware Division of Public Health to receive matching grants for wastewater, surface water and drinking water project planning.

The COVID-19 pandemic has highlighted the critical role of genomic surveillance for guiding policy and control. Timeliness is key, but sequence alignment and phylogeny slow most surveillance techniques. Millions of SARS-CoV-2 genomes have been assembled. Phylogenetic methods are ill equipped to handle this sheer scale. We introduce a pangenomic measure that examines the information diversity of a k-mer library drawn from a country's complete set of clinical, pooled, or wastewater sequence. Quantifying diversity is central to ecology. Hill numbers, or the effective number of species in a sample, provide a simple metric for comparing species diversity across environments. The more diverse the sample, the higher the Hill number. We adopt this ecological approach and consider each k-mer an individual and each genome a transect in the pangenome of the species. Structured in this way, Hill numbers summarize the temporal trajectory of pandemic variants, collapsing each day's assemblies into genome equivalents. For pooled or wastewater sequence, we instead compare days using survey sequence divorced from individual infections. Across data from the UK, USA, and South Africa, we trace the ascendance of new variants of concern as they emerge in local populations well before these variants are named and added to phylogenetic databases. Using data from San Diego wastewater, we monitor these same population changes from raw, unassembled sequence. This history of emerging variants senses all available data as it is sequenced, intimating variant sweeps to dominance or declines to extinction at the leading edge of the COVID-19 pandemic.
