This story is part of Down to Earth, a Vox reporting initiative on the science, politics, and economics of the biodiversity crisis. A decade ago, a team of salamander researchers made a dire prediction: that climate change would make much…
(University of Oldenburg ) The depths of the Black Sea store comparatively large amounts of organic carbon. A research team led by scientists from the University of Oldenburg, Germany, has now presented a new hypothesis as to why organic compounds accumulate in this semi-enclosed sea and other oxygen-depleted waters. Reactions with hydrogen sulfide play an important role in stabilizing carbon compounds, the researchers posit in the scientific journal Science Advances. This negative feedback in the climate system could counteract global warming over geological periods.
Quoting from Shane Cruzen’s letter of April 8: “[Chico’s] climate action plan prioritizes strictly electric construction moving forward, electrifying all municipal buildings, replacing gas appliances with electric appliances, providing 100% renewably generated energy to the community, completing the Chico bike master…
Reduced microbial stability linked to soil carbon loss in active layer under alpine permafrost degra
(Chinese Academy of Sciences Headquarters) Chinese researchers headed by Prof. CHEN Shengyun from the Northwest Institute of Eco-Environment and Resources (NIEER) and XUE Kai from University of Chinese Academy of Sciences have recently discovered links between reduction in microbial stability and soil carbon loss in the active layer of degraded alpine permafrost on the Qinghai-Tibet Plateau.
(University of Vienna) While best known as the code for genetic information, DNA is also a nutrient for specialized microbes. An international team of researchers led by Kenneth Wasmund and Alexander Loy from the University of Vienna has discovered several bacteria in sediment samples from the Atlantic Ocean that use DNA as a food source. One bacterium newly named by the team in fact is a true expert in degrading DNA. The study is now published in Nature Microbiology.
Even without new fossil fuel projects, global warming will still exceed 1.5℃. But renewables might make it possible – The Conversation AU
The International Energy Agency (IEA) last month made global headlines when it declared there is no room for new fossil fuel investment if we’re to avoid catastrophic climate change. However, our new research suggests the horse may have already bolted….
Researchers Now Have AI Device to Sniff Out Cancer in Blood Samples With 95% Accuracy For Hard to Detect Types
An odor-based test that sniffs out vapors emanating from blood samples was able to distinguish between benign and pancreatic and ovarian cancer cells with up to 95 percent accuracy, according to a new study from researchers at the University of Pennsylvania and Pennâs Perelman School of Medicine. The findings suggest that the Penn-developed tool â […]
Effects of ‘Fenton-like’ reactions of ferric oxalate on atmospheric oxidation processes and radiative forcing
(Institute of Atmospheric Physics, Chinese Academy of Sciences) A new study evaluates the contribution of the Fenton-like reaction to atmospheric oxidation, and improves the consistency of model-simulated and field-observed secondary organic aerosol budgets.
A 3-D printed electronic nose has been developed that ‘sniffs out’ Covid in just seconds. The device smells chemicals in infected individuals, opening the door to large-scale testing across the world. Scientists say it could be used at airports, offices, factories, and even football, rugby, and cricket grounds. Project leader Professor Noam Sobel explained: “The […]
