With desert cities like Phoenix and Tucson bracing for their allotments of Colorado River water to be slashed dramatically, San Diego County's water agency could for the first time sell some of its water to other states by drawing on its ample supplies from the nation's largest desalination plant.
A research team composed of plant virologists from the Plant Virus Department at Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures, the Italian National Research Council and BASF-Nunhems Italy, has recently published the findings of a scientific collaboration on investigating the occurrence of resistance-breaking strains of tomato spotted wilt virus (TSWV) in tomato and pepper fields. The results, which prove for the first time the emergence of double resistance-breaking strains (D-RB) of TSWV in agricultural settings, have been published in Virology.
In 2009, a scandal was exposed at a cemetery just outside of Chicago. Workers at Burr Oak Cemetery in Alsip, Illinois, were accused of exhuming old graves, dumping the remains elsewhere on the cemetery grounds, and reselling the burial plots. When the case went to trial in 2015, one key piece of evidence was a tiny clump of moss.
Just like in the modern world, people in ancient times wanted to know how to live a long and healthy life.
The implementation of green axes and the reduction of motorized traffic in cities is effectively consolidating itself as a strategy to significantly lower environmental noise levels. A study conducted in the city of Barcelona shows that, one year after pedestrianizing several streets, the average daily sound level decreased by 3.1 decibels (dB).
Initial tests with a natural dye produced by the Amazonian fungus Talaromyces amestolkiae show that eco-friendly cosmetics, such as face creams, gel sticks, and shampoos, can be developed with antioxidant and antibacterial properties. This finding is significant because microbial dyes, which are still underexplored in cosmetic research, can serve as a sustainable alternative to synthetic dyes.
For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo surrounding the Geminga pulsar wind nebula (PWN). This observation extends to the highest energies, above 100 tera-electron volts (TeV), providing new insights into the behavior of cosmic rays and magnetic fields within the Milky Way.
Cancer cell-derived small extracellular vesicles (sEVs) can travel from distant tumors through the bloodstream and kidneys and be excreted into urine, as reported by researchers at Science Tokyo. Using sophisticated molecular tagging systems in mouse models of brain, lung and pancreatic cancer, the researchers directly traced sEVs from tumors to urine. They also revealed that the kidney's glomerular cells actively transport sEVs across the filtration barrier, supporting their use in emerging urine-based cancer diagnostics.
NASA announced it had found the source of a helium flow blockage that forced it to roll the Artemis II rocket back from the launch pad at Kennedy Space Center and delay its lunar fly-by mission until at least April.
Photocatalysis promises an efficient conversion of abundant solar energy into usable chemical energy. Polyheptazine imides have some key structural and functional twists that make them especially interesting for photocatalysis. So far, there is only limited knowledge about how structural changes affect the electronic and optical properties of the many material candidates in this class. A team led by researchers from the Center for Advanced Systems Understanding (CASUS) at HZDR has now presented a reliable and reproducible theoretical method to solve this challenge that was confirmed by measurements done on genuine candidate materials.
