Immune system in the spotlight      (via sciencedaily.com)     Original source 

Our immune system is always on alert, detecting and eliminating pathogens and cancer cells. Cellular control mechanisms cause diseased cells to present antigens on their surface like signs for the immune system. For analysis of the necessary complex antigen processing and transport processes in real time, researchers have developed a 'cage' that is opened with light to release trapped antigens at a specific place and time.

Ancient microbes offer clues to how complex life evolved      (via sciencedaily.com)     Original source 

Researchers have discovered that a single-celled organism, a close relative of animals, harbors the remnants of ancient giant viruses woven into its own genetic code. This finding sheds light on how complex organisms may have acquired some of their genes and highlights the dynamic interplay between viruses and their hosts.

Capturing carbon with energy-efficient sodium carbonate-nanocarbon hybrid material      (via sciencedaily.com)     Original source 

Carbon capture is a promising approach for mitigating carbon dioxide (CO2) emissions. Different materials have been used to capture CO2 from industrial exhaust gases. Scientists developed hybrid CO2 capture materials containing sodium carbonate and nanocarbon prepared at different temperatures, tested their performance, and identified the optimal calcination temperature condition. They found that the hybrid material exhibits and maintains high CO2 capture capacity for multiple regeneration cycles at a lower temperature, making it cost- and energy-effective.

Local dragonflies expose mercury pollution patterns      (via sciencedaily.com)     Original source 

A new study has unveiled surprising findings about mercury pollution: where it comes from and how it moves through the environment vary significantly depending on the ecosystem. In drier regions, most mercury is deposited through rain and snow. In wetter, forested areas, gaseous mercury from the air sticks to leaves, which then fall and carry the toxin into the ground.

Building a roadmap to bioengineer plants that produce their own nitrogen fertilizer      (via sciencedaily.com)     Original source 

Nitrogen fertilizers make it possible to feed the world's growing population, but they are also costly adn harm ecosystems. However, a few plants have evolved the ability to acquire their own nitrogen with the help of bacteria, and a new study helps explain how they did it, not once, but multiple times.

Complex impact of large wildfires on ozone layer dynamics      (via sciencedaily.com)     Original source 

In a revelation highlighting the fragile balance of our planet's atmosphere, scientists have uncovered an unexpected link between massive wildfire events and the chemistry of the ozone layer. Using satellite data and numerical modeling, the team discovered that an enormous smoke-charged vortex nearly doubles the southern hemispheric aerosol burden in the middle stratosphere of the Earth and reorders ozone depletion at different heights. This study reveals how wildfires, such as the catastrophic 2019/20 Australian bushfires, impact the stratosphere in previously unseen ways.

High and low tide cause low and high methane fluxes      (via sciencedaily.com)     Original source 

Methane, a strong greenhouse gas that naturally escapes from the bottom of the North Sea, is affected by the pressure of high or low tide. Methane emissions from the seafloor can be just easily three times as much or as little, depending on the tide, according to a new study.

A better way to make RNA drugs      (via sciencedaily.com)     Original source 

RNA drugs are the next frontier of medicine, but manufacturing them requires an expensive and labor-intensive process that limits production and produces metric tons of toxic chemical waste. Researchers report a new, enzyme-based RNA synthesis method that can produce strands of RNA with both natural and modified nucleotides without the environmental hazards.

How plant cold specialists can adapt to the environment      (via sciencedaily.com)     Original source 

Evolutionary biologists studied spoonworts to determine what influence genome duplication has on the adaptive potential of plants. The results show that polyploids -- species with more than two sets of chromosomes -- can have an accumulation of structural mutations with signals for a possible local adaptation, enabling them to occupy ecological niches time and time again.

Nanoplastics and 'forever chemicals' disrupt molecular structures, functionality      (via sciencedaily.com)     Original source 

Researchers have made significant inroads in understanding how nanoplastics and per- and polyfluoroalkyl substances (PFAS) -- commonly known as forever chemicals -- disrupt biomolecular structure and function. The work shows that the compounds can alter proteins found in human breast milk and infant formulas -- potentially causing developmental issues downstream.
