Traffic-related ultrafine particles hinder mitochondrial functions in olfactory mucosa      (via sciencedaily.com)     Original source 

Ultrafine particles, UFPs, the smallest contributors to air pollution, hinder the function of mitochondria in human olfactory mucosa cells, a new study shows. The study showed that traffic-related UFPs impair mitochondrial functions in primary human olfactory mucosa cells by hampering oxidative phosphorylation and redox balance.

Research sheds light on the role of PTPRK in tissue repair and cancer      (via sciencedaily.com)     Original source 

New research has advanced our knowledge of multiple roles for PTPRK, a receptor tyrosine phosphatase linked to the regulation of cell-cell adhesion, growth factor signalling and tumor suppression. Through a characterization of the function of PTPRK in human cell lines and mice, the team distinguished catalytic and non-catalytic functions of PTPRK. The findings extend what is known about the signalling mechanisms involving PTPRK as a phosphatase and its role in colorectal health but also shed new light on the extent of its function via non-catalytic signalling mechanisms.

Manufacturing perovskite solar panels with a long-term vision      (via sciencedaily.com)     Original source 

Researchers working at the forefront of an emerging photovoltaic (PV) technology are thinking ahead about how to scale, deploy, and design future solar panels to be easily recyclable. Solar panels made of perovskites may eventually play an important role amid global decarbonization efforts to reduce greenhouse gas emissions. As the technology emerges from the testing stages, it is a perfect time to think critically about how best to design the solar panels to minimize their impact on the environment decades from now.

Better carbon storage with stacked geology      (via sciencedaily.com)     Original source 

According to new research subsurface reservoirs that are covered by a collection of hundreds of smaller lids -- collectively called a 'composite confining system' -- may be the better option for keeping carbon trapped for the long term. That's good news for the carbon storage industry. This type of distributed system is common in a range of geological environments.

Researchers warn of unprecedented arsenic release from wildfires      (via sciencedaily.com)     Original source 

The wildfire season of 2023 was the most destructive ever recorded in Canada and a new study suggests the impact was unprecedented. It found that four of the year's wildfires in mine-impacted areas around Yellowknife, Northwest Territories potentially contributed up to half of the arsenic that wildfires emit globally each year.

Best bioenergy crops for sustainable aviation fuels by U.S. region, policy goals      (via sciencedaily.com)     Original source 

Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock -- corn stover, energy sorghum, miscanthus or switchgrass -- performed best in a specific region of the rainfed United States. Their study will help growers and policymakers select the feedstocks most suited to meeting goals like reducing production costs, lowering greenhouse gas emissions and building soil carbon stocks.
