Gene regulatory networks (GRNs) depict the regulatory mechanisms of genes within cellular systems as a network, offering vital insights for understanding cell processes and molecular interactions that determine cellular phenotypes. Transcriptional re.....»»
Live imaging reveals key cell dynamics in 3D organ formation in Drosophila
Animal development requires successive changes in cell and tissue structures. To form complex 3D organs, cell shapes must adapt to support tissue morphogenesis. However, our understanding of how cellular structure changes are coupled with dynamic tis.....»»
Compound vital for all life likely played a role in life"s origin, suggests synthesis study
A chemical compound essential to all living things has been synthesized in a lab in conditions that could have occurred on early Earth, suggesting it played a role at the outset of life, finds a new study led by University College London researchers......»»
The modeling and simulation of self-organized intracellular twisters in the Drosophila oocyte
Cytoplasmic streaming is the large-scale motion of cytoplasm (i.e., gelatinous liquid inside cells) inside a living cell. This flow, known to regulate various intracellular processes, can vary greatly between different cell types at different stages.....»»
Study reveals molecular mechanisms behind hibernation in mammals
Researchers have shed light on the molecular mechanisms underlying hibernation, publishing their findings today as a Reviewed Preprint in eLife......»»
Researchers develop new integration technique for efficient coupling of III-V and silicon
Researchers at the Hong Kong University of Science and Technology (HKUST) have developed a new integration technique for efficient integration of III-V compound semiconductor devices and silicon, paving the way for photonic integration at low cost, l.....»»
New research reveals mechanisms of stiffening in paper pulp, could lead to improved recyclability
One of the problems with paper recycling is that the fibers stiffen during the dewatering and drying processes, also known as hornification. The same thing happens to dishcloths, for example; they stiffen over time. New research can now explain the m.....»»
Nanofiber-coated cotton bandages fight infection and speed healing
An interdisciplinary team of Cornell researchers has identified an innovative way to harness the antioxidant and antibacterial properties of the botanical compound lawsone to make nanofiber-coated cotton bandages that fight infection and help wounds.....»»
Unlocking artemisinin production secrets in Artemisia annua: The role of DBR2-like gene variations
Artemisia annua is the only known plant source of potent antimalarial artemisinins, and its chemotypes are classified as low- and high-artemisinin producing (LAP and HAP). However, the different mechanisms of artemisinin production by these two chemo.....»»
Manipulating host defenses: Unveiling the role of a powdery mildew effector in grapevine infection
Powdery mildew, caused by Erysiphe necator, is a significant threat to grapevine health, utilizing secreted effector proteins (CSEPs) to suppress plant defenses. Despite knowledge of plant immune mechanisms, the specific roles of E. necator's CSEPs i.....»»
Shedding light on shadows: Unveiling the impact of low light on tomato disease susceptibility and defense mechanisms
The global challenge of plant disease outbreaks under low light intensities leads to significant crop yield losses, with the mechanisms of low light's impact on plant defense poorly understood. Research has identified high light conditions as enhanci.....»»
Unveiling and decoding the regulatory mechanisms of secondary cell wall formation
Wood quality is primarily determined by the properties of its secondary cell wall (SCW). Gaining insight into the molecular processes governing SCW development is crucial for the genetic enhancement of wood quality. Although it's established that a m.....»»
Endangered seabird shows surprising individual flexibility to adapt to climate change
How individual animals respond to climate change is key to whether populations will persist or go extinct. Many species are shifting their ranges as the environment warms, but up to now the mechanisms underlying this have been unclear. For Europe's m.....»»
Study reveals mechanisms behind how growing cells maintain their mojo by scaling up biosynthesis
