'Itinerant breeding' in East Coast shorebird species      (via sciencedaily.com)     Original source 

A study has found direct evidence of a species -- the American woodcock, a migratory shorebird from eastern and central North America -- that overlaps periods of migration and reproduction, a rare breeding strategy known as 'itinerant breeding.'

Lemur's lament: When one vulnerable species stalks another      (via sciencedaily.com)     Original source 

What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.

Key protein regulates immune response to viruses in mammal cells      (via sciencedaily.com)     Original source 

Researchers have revealed the regulatory mechanism of a specific protein, TRBP, that plays a key role in balancing the immune response triggered by viral infections in mammal cells. These findings could help drive the development of antiviral therapies and nucleic acid medicines to treat genetic disorders.

Light show in living cells      (via sciencedaily.com)     Original source 

Observing proteins precisely within cells is extremely important for many branches of research but has been a significant technical challenge -- especially in living cells, as the required fluorescent labeling had to be individually attached to each protein. The research group has now overcome this hurdle: With a method called 'vpCells,' it is possible to label many proteins simultaneously, using five different fluorescent colors.

Why can zebrafish regenerate damaged heart tissue, while other fish species cannot?      (via sciencedaily.com)     Original source 

A heart attack will leave a permanent scar on a human heart, yet other animals, including zebrafish, can clear cardiac scar tissue and regrow damaged muscle as adults. Biologists sheds new light on how zebrafish heal heart tissue by comparing how this species responds to heart injury with medaka, a fish species that cannot regenerate cardiac tissue.

Fourteen years after the Gulf of Mexico oil spill, endemic fishes face an uncertain future      (via sciencedaily.com)     Original source 

The 2010 Gulf of Mexico Deepwater Horizon oil spill, the largest accidental spill in history, released almost 100 million gallons of oil, causing significant pollution. A decade later, its long-term effects remain unclear. A study investigating the impact on endemic fish species found 29 of 78 species unreported in museum collections since the spill, suggesting potential loss of biodiversity.

Marine microbial populations: Potential sensors of the global change in the ocean      (via sciencedaily.com)     Original source 

Animal and plant populations have been extensively studied, which has helped to understand ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations due to the impossibility of isolating, culturing and analyzing the genetic content of the different species and their individuals in the laboratory. Therefore, although it is known that populations of microorganisms include a great diversity, this remains largely uncharacterized.

RNA's hidden potential: New study unveils its role in early life and future bioengineering      (via sciencedaily.com)     Original source 

The origin of life continues to remain a matter of debate. The ribonucleic acid (RNA) world hypothesis proposes that 'ribozymes' which store genetic information and possess catalytic functions may have supported the activities of early life forms. Now, researchers explore how RNA elongation is regulated allosterically, shedding light on its impact on early life processes and offering insights into the fabrication of arbitrary RNA nanostructures with various modern applications.

Plant sensors could act as an early warning system for farmers      (via sciencedaily.com)     Original source 

Using a pair of sensors made from carbon nanotubes, researchers discovered signals that help plants respond to stresses such as heat, light, or attack from insects or bacteria. Farmers could use these sensors to monitor threats to their crops, allowing them to intervene before the crops are lost.

Copper beads in pig feed reshape swine gut microbiome      (via sciencedaily.com)     Original source 

Copper is a natural antimicrobial material that, when added to pig feed, may promote the growth and health of the animals. Since pigs can tolerate high levels of the metal, researchers recently investigated whether copper might be used to promote their gut health and reduce the shedding of microbes to the environment.

Older males out-compete young males outside breeding pairs, bird study shows      (via sciencedaily.com)     Original source 

Young male blue tits are less successful in fathering offspring outside their breeding pair, not because of a lack of experience, but because they are outcompeted by older males, researchers report.
