Up in smoke: California's greenhouse gas reductions could be wiped out by 2020 wildfires.

Environ Pollut 2022 Aug 5:119888. Epub 2022 Aug 5.

Department of Environmental Health Sciences, Fielding School of Public Health, University of California, Los Angeles, 650 Charles E. Young Dr. S., 56-070 CHS Box 951772, Los Angeles, CA, 90095, USA. Electronic address:

In this short communication, we estimate that California's wildfire carbon dioxide equivalent (COe) emissions from 2020 are approximately two times higher than California's total greenhouse gas (GHG) emission reductions since 2003. Without considering future vegetation regrowth, COe emissions from the 2020 wildfires could be the second most important source in the state above either industry or electrical power generation. Regrowth may partly of fully occur over a long period, but due to exigencies of the climate crisis most of the regrowth will not occur quickly enough to avert greater than 1. Read More

Pore-scale processes in tertiary low salinity waterflooding in a carbonate rock: Micro-dispersions, water film growth, and wettability change.

J Colloid Interface Sci 2022 Jun 18;628(Pt A):486-498. Epub 2022 Jun 18.

Department of Earth Science and Engineering, Imperial College London, SW7 2AZ London, United Kingdom.

Hypothesis: The wettability change from oil-wet towards more water-wet conditions by injecting diluted brine can improve oil recovery from reservoir rocks, known as low salinity waterflooding. We investigated the underlying pore-scale mechanisms of this process to determine if improved recovery was associated with a change in local contact angle, and if additional displacement was facilitated by the formation of micro-dispersions of water in oil and water film swelling.

Experiments: X-ray imaging and high-pressure and temperature flow apparatus were used to investigate and compare high and low salinity waterflooding in a carbonate rock sample. Read More

The results indicated that DHTR presented with severe internal nutrient loadings, and the N and P fluxes showed significant spatiotemporal variations. Read More

Plasma membrane-to-organelle communication in plant stress signaling.

Curr Opin Plant Biol 2022 Aug 5;69:102269. Epub 2022 Aug 5.

Department of Plant Biochemistry, Centre for Plant Molecular Biology (ZMBP), Eberhard Karls University, D-72076 Tübingen, Germany. Electronic address:

Intracellular compartments engage in extensive communication with one another, an essential ability for cells to respond and adapt to changing environmental and developmental conditions. The plasma membrane (PM), as the interface between the cellular and the outside media, plays a central role in the perception and relay of information about external stimuli, which needs to be ultimately addressed to the relevant subcellular organelles. Interest in PM-organelle communication has increased dramatically in recent years, as examples arise that illustrate different strategies through which information from the PM can be transmitted.
