Israel’s military has begun injecting “high-flow” seawater into Hamas-built tunnels beneath the Gaza Strip as part of its attempt to “neutralize terrorist infrastructures.”On 30 January, the Israel Defense Forces (IDF) confirmed that the plan to flood tunnels under the Gaza Strip, a strategy that has been the subject of rumours since December, is being implemented at a number of undisclosed locations. The IDF’s statement added that the move was a “significant engineering and technological breakthrough” and that locations…

An international team of researchers has discovered that the concentrations of plastic in freshwater environments, such as lakes and reservoirs, are higher than those found in oceanic “garbage patches.” The study, published in Nature, involved the analysis of surface waters from 38 lakes and reservoirs, revealing microplastic presence in all samples.Research from the Global Lake Ecological Observatory Network finds that freshwater environments like lakes and reservoirs have higher concentrations of plastic than oceanic…

But that has long-since ceased to be true for all of the continent. It is also home to oilfields and pipelines, mines and various other industrial activities. The corresponding facilities were built on a foundation once considered to be particularly stable and…

DOI: 10.1016/j.scitotenv.2022.159360 Despite the risks to human health, testing for arsenic isn't required for most private drinking wells in New Jersey. To help address this regulatory gap, a Rutgers researcher developed a machine learning model that can estimate arsenic contamination in private wells without the need to sample the water itself.…

Illustration of bacteriophage viruses attacking bacterium.Scientists harness bacteria-eating viruses to create a powerful new weapon against contamination and infection.Researchers have developed a way to coax bacteriophages – harmless viruses that eat bacteria – into linking together and forming microscopic beads. Those beads can safely be applied to food and other materials to rid them of harmful pathogens such as E. coli O157. Each bead is about 20 microns, (one 50th of a millimeter) in diameter and is loaded with…

Dangerous, radioactive particles are all over an elementary school in suburban St. Louis, according to a recently published analysis by Boston Chemical Data Corp.The testing follows an earlier assessment by the Army Corps of Engineers that also found elevated levels of radiation near Jana Elementary School in Florissant, Missouri. However, the new report—which included indoor testing and more extensive samples from the school grounds—is even more startling, confirming fears of contamination.Based on dust and soil samples…
