Feeding the global population currently requires clearing vast forests for soy plantations or heavily depleting the oceans for fish meal. What if the agricultural industry could bypass the farm and the sea entirely, opting instead to brew high-quality food from a problematic greenhouse gas? A rigorous new life-cycle assessment demonstrates that cultivating methane-consuming microbes is far more than an experimental concept—it is a highly lucrative, environmentally superior reality.

Driving this evaluation are corresponding authors Yanping Liu and Ziyi Yang from the Beijing University of Chemical Technology. Their latest work, appearing in the journal Carbon Research, stacks microbial protein directly against conventional agricultural staples. The verdict leans heavily in favor of the bioreactor over traditional harvesting.

The research team modeled three distinct supply chains: soybean meal, fish meal, and protein derived from methane-oxidizing bacteria (MOB). The legacy methods carried expectedly heavy environmental baggage. Soy production was dominated by massive land footprints and agricultural chemical inputs. Meanwhile, the fish meal industry demanded extensive fuel consumption and inflicted severe stress on marine ecosystems.

In the complex world of soil and water chemistry, certain minerals act like microscopic sponges, soaking up pollutants and keeping our environment safe. Among the most dangerous of these pollutants is hexavalent chromium—Cr(VI)—a highly toxic and mobile substance often found at industrial and mining sites. Now, a groundbreaking study published in Carbon Research has identified the specific "superstar" minerals that are best at neutralizing this threat while simultaneously locking away organic carbon.

The research, led by Professor Bin Dong from Tongji University, focuses on the interaction between dissolved organic matter (DOM) and various iron (oxyhydr)oxides. The team discovered that low-crystallinity minerals, specifically ferrihydrite, are far more effective at managing chromium than their more "perfect" crystalline cousins like goethite and hematite. This work represents a major collaborative effort centered at the College of Environmental Science and Engineering at Tongji University and the Shanghai Institute of Pollution Control and Ecological Security, with support from the YANGTZE Eco-Environment Engineering Research Center and Guilin University of Technology. "Nature has a built-in filtration system, but not all minerals are created equal," says Professor Bin Dong. "By understanding the molecular handshake between organic matter and iron minerals, we can design smarter, nature-based solutions to clean up heavily contaminated mine soils while helping the planet store more carbon."

When it comes to error sensitivity, quantum computers are huge divas. Virginia Tech physicists devised a technique that draws on hidden quantum geometry to simplify the problem.

Rice University chemistry professor Zachary Ball recently published a paper describing a new way to target a common but understudied posttranslational modification called pyroglutamate.
