A mitochondrial self-preservation mechanism
Mitochondria, the powerhouse of the cell, convert sustenance into energy, fueling the cell's activities. In addition to power, mitochondria also produce reactive oxygen species, byproduct molecules primed to help facilitate communication among the ot.....»»
Epigenetic regulator MOF drives mitochondrial metabolism, new study shows
The intricate control of cellular metabolism relies on the coordinated and harmonious interplay between the nucleus and mitochondria. On the one hand, mitochondria are the hub for the production of essential metabolites, which aside from being requir.....»»
How proteins roll the dice to determine bee sex
To date it has been unclear exactly how the sex of a bee is determined. A research team from Heinrich Heine University Düsseldorf (HHU) including biologists and chemists has now identified a key gene and the molecular mechanism linked with it. In th.....»»
Pheromones found to influence death feigning behavior in beetles
Predation is a driving force in the evolution of anti-predator strategies, and death feigning, characterized by immobility in response to threats, is a common defensive mechanism across various animal species. While this behavior can enhance an indiv.....»»
Scientists shed light on how stressed cells sequester protein-forming mRNAs
Researchers at Weill Cornell Medicine have illuminated one of the important ways that cells respond to stress. The findings could also be relevant to Alzheimer's, ALS and other diseases in which this mechanism may be abnormally active......»»

Coating something rare—tiny shards of diamond—with the main ingredient in sand might sound unusual, but the end result turns out to have a number of valuable applications. The trick is, nobody knows for sure how the two materials bond......»»
Multi-objective decision support tools for protected area selection to reach the 30x30 target
The establishment and preservation of protected areas is a key measure for achieving the goals set during the World Conference on Nature in December 2022. However, such protected areas often need to fulfill multiple objectives, such as climate protec.....»»
Mature sperm lack intact mitochondrial DNA, study finds
New research provides insight about the bedrock scientific principle that mitochondrial DNA—the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the body—is exclusively passed down by the mother......»»
Notorious fungus Aspergillus fumigatus completely scrambles its genome after just one bout of sex
Researchers at Wageningen University & Research (WUR) have found that Aspergillus fumigatus produces more meiotic crossovers than any other organism. This means that the fungus can establish its complex resistance mechanism after just one cycle of se.....»»
