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.

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.

Study examines urban forests across the United States      (via sciencedaily.com)     Original source 

Tree-planting campaigns have been underway in the United States, especially in cities, as part of climate mitigation efforts given the many environmental benefits of urban forests. But a new study finds that some areas within urban forests in the U.S., may be more capable than trees growing around city home lawns in adapting to a warmer climate.

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.

A stealth fungus has decimated North American bats but scientists may be a step closer to treating white-nose syndrome      (via sciencedaily.com)     Original source 

An invasive fungus that colonizes the skin of hibernating bats with deadly consequences is a stealthy invader that uses multiple strategies to slip into the small mammals' skin cells and quietly manipulate them to aid its own survival. The fungus, which causes the disease white-nose syndrome, has devastated several North American species over the last 18 years.

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.

Researchers develop a way to make lifesaving phages accessible, transportable and much easier to use      (via sciencedaily.com)     Original source 

Researchers have developed a simple way to bring bacteriophage therapy into much closer reach for clinicians struggling to save patients with antimicrobial-resistant infections. The technology makes it possible to sort through hundreds or even thousands of phages in less than two hours to identify which will respond to a particular infection.

Opening the right doors: 'Jumping gene' control mechanisms revealed      (via sciencedaily.com)     Original source 

International joint research led by Akihisa Osakabe and Yoshimasa Takizawa of the University of Tokyo has clarified the molecular mechanisms in thale cresses (Arabidopsis thaliana) by which the DDM1 (Decreased in DNA Methylation 1) protein prevents the transcription of 'jumping genes.' DDM1 makes 'jumping genes' more accessible for transcription-suppressing chemical marks to be deposited. Because a variant of this protein exists in humans, the discovery provides insight into genetic conditions caused by such 'jumping gene' mutations.
