Brevia
- Isolation of an Algal Morphogenesis Inducer from a Marine Bacterium
The leafy morphology of marine green algae is maintained by a chemical produced by bacteria on their surfaces and not by substances in the ocean.
Research Articles
- Chaperone Activity of Protein O-Fucosyltransferase 1 Promotes Notch Receptor Folding
An enzyme thought to add sugar groups to a key receptor protein as it travels to the membrane unexpectedly also acts as a chaperone to ensure correct folding of the receptor.
- Regulation of the Polarity Protein Par6 by TGFß Receptors Controls Epithelial Cell Plasticity
Maturing epithelial cells acquire the ability to migrate when a growth hormone binds to its receptor, triggering destruction of the proteins involved in cellular adhesion.
Reports
- The Magnetic Field of the Large Magellanic Cloud Revealed Through Faraday Rotation
Maturing epithelial cells acquire the ability to migrate when a growth hormone binds to its receptor, triggering destruction of the proteins involved in cellular adhesion.
- Molecular Mechanisms for the Functionality of Lubricant Additives
Simulations show that the zinc in motor oil additives reduces wear by polymerizing under the high-pressure conditions in steel engines, creating a protective film.
- High-Resolution Surface-Wave Tomography from Ambient Seismic Noise
Information contained in the ambient noise from the atmosphere and ocean recorded by seismometers can be used to construct high-resolution images of the Earth's crust.
- Worldwide Phylogeography of Wild Boar Reveals Multiple Centers of Pig Domestication
Mitochondrial DNA sequences of wild and domestic pigs implies that wild boar were domesticated at least seven times throughout Eurasia.
- High-Throughput Mapping of a Dynamic Signaling Network in Mammalian Cells
A rapid method for finding hundreds of connections in cellular signaling networks shows how a network of over 900 interactions controlled by a single growth factor regulates cell adhesion.
- A Transmembrane Intracellular Estrogen Receptor Mediates Rapid Cell Signaling
Estrogen may act through a receptor in the membrane of a cytoplasmic organelle in addition to the classical estrogen receptor in the nucleus.
- Differential Lysosomal Proteolysis in Antigen-Presenting Cells Determines Antigen Fate
Antigen-presenting cells like dendritic cells and white blood cells degrade internalized antigens slowly, preserving them for efficient tolerance induction and immunity.
- BZR1 Is a Transcriptional Repressor with Dual Roles in Brassinosteroid Homeostasis and Growth Responses
A newly described transcription factor regulates both the biosynthesis of a steroid hormone in plants and how that hormone controls growth.
- Insect Sex-Pheromone Signals Mediated by Specific Combinations of Olfactory Receptors
In the silk moth, and perhaps other insects, responses to sex pheromones require expression of both the appropriate pheromone receptor and a general olfactory receptor.
- Adaptive Coding of Reward Value by Dopamine Neurons
In monkeys, dopamine neurons that influence motivation adjust their activity according to the expected size of a juice reward.
