The underground network: Decoding the dynamics of plant-fungal symbiosis      (via sciencedaily.com)     Original source 

The intricate dance of nature often unfolds in mysterious ways, hidden from the naked eye. At the heart of this enigmatic tango lies a vital partnership: the symbiosis between plants and a type of fungi known as arbuscular mycorrhizal (AM) fungi. New groundbreaking research delves into this partnership, revealing key insights that deepen our understanding of plant-AM fungi interactions and could lead to advances in sustainable agriculture.

Sparrows uniquely adapted to Bay Area marshes are losing their uniqueness      (via sciencedaily.com)     Original source 

How does loss of habitat affect the animals still living there? A genetic study of saltwater-adapted Savannah sparrows around the San Francisco Bay Area shows that the 90% loss of tidal marsh habitat has led to more interbreeding with freshwater-adapted Savannah sparrows, diminishing their genetic adaptation to saltwater, such as enlarged kidneys and larger beak. This could lessen their ability to live in a saltwater habitat.

Innovative microscopy technique reveals secrets of lipid synthesis inside cells      (via sciencedaily.com)     Original source 

Researchers have made a pivotal discovery in the field of cellular microscopy. The team has successfully developed Two-Color Infrared Photothermal Microscopy (2C-IPM), a novel technology designed to investigate neutral lipids within lipid droplets of living cells. This new microscopy can be used with isotope labeling, which allows for the detailed monitoring of neutral lipid synthesis within individual lipid droplets.

Syphilis-like diseases were widespread in Americas before arrival of Columbus, researchers find      (via sciencedaily.com)     Original source 

Researchers have discovered the genetic material of the pathogen Treponema pallidum in the bones of people who died in Brazil 2,000 years ago. This is the oldest verified discovery of this pathogen thus far, and it proves that humans were suffering from diseases akin to syphilis -- known as treponematoses -- long before Columbus's discovery of America. The new findings call into question previous theories concerning the spread of syphilis by the Spanish conquistadors.

New study unveils how plants control the production of reactive oxygen species      (via sciencedaily.com)     Original source 

Reactive oxygen species (ROS), though generally regarded as toxic byproducts of biological processes, serve many important functions in plants. However, the precise mechanism that plants use to regulate the production of ROS remains elusive. In a recent study, researchers clarified how an important ROS-generating enzyme is activated, revealing mechanisms likely conserved across all land plants. Their findings could pave the way for breakthroughs in agricultural and environmental remediation tools.

Study offers rare long-term analysis of techniques for creating standing dead trees for wildlife habitat      (via sciencedaily.com)     Original source 

Ecologists have long known that standing dead trees, commonly referred to as snags, are an important habitat element for forest dwellers and act as a driver of biodiversity. They're so important that in some managed forests, snag creation is part of the conservation tool kit -- i.e., crews sometimes convert a percentage of live trees into dead ones through techniques ranging from sawing off their tops to wounding their trunks to injecting them with disease-causing fungi.

Complex green organisms emerged a billion years ago      (via sciencedaily.com)     Original source 

Of all the organisms that photosynthesize, land plants have the most complex form. How did this morphology emerge? A team of scientists has taken a deep dive into the evolutionary history of morphological complexity in streptophytes, which include land plants and many green algae. Their research allowed them to go back in time to investigate lineages that emerged long before land plants existed.

A window into plant evolution: The unusual genetic journey of lycophytes      (via sciencedaily.com)     Original source 

An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics.
