A sophisticated mechanism that allows plant roots to quickly respond to changes in soil conditions has been identified by an international research team.
By capturing the crystal structure of RNA polymerase during a nontraditional form of transcription -- reiterative transcription -- researchers have identified a new pathway used by RNA to exit an enzyme.
Through their pattern of firing, neurons influence the behavior of the cells that upon maturation will provide insulation of neuronal axons, according to a new study publishing Aug. 22 in the open-access journal PLOS Biology by Balint Nagy, Maria Kukley and colleagues at the University of Tübingen, Germany. The findings suggest the existence of a complex and nuanced interplay between neurons and the non-neuronal cells that support and protect them.
About two years ago, scientists from the University of Würzburg discovered that a certain class of receptors is capable of perceiving mechanical stimuli. Now they have begun to unravel the molecular mechanisms behind the discovery.
Scientists have discovered a new way of attacking esophageal cancer cells that could make use of an existing drug in a new approach to treatment. Their study discovered a genetic weakness or 'Achilles' heel' in esophageal cancer cells that makes them particularly sensitive to a drug called ibrutinib which is already used to treat blood cancer.
The link between a mother's body mass index (BMI) before pregnancy and the metabolic traits of her children is likely mediated by shared genetics and familial lifestyle rather than effects on the fetus during gestation, according to study published this week in PLOS Medicine by Debbie Lawlor of the University of Bristol, UK, and colleagues.
The study was based on observations that the more successful crops in areas typically affected by drought are usually protected by a thicker layer of leaf wax than other plants.
Fewer trips to the dentist may be in your future, and you have mussels to thank.
A longstanding obstacle to the market for bovine embryos is about to be removed. Researchers have described a hitherto unknown mechanism of lipid accumulation in oocytes that limits the success of in vitro production of bovine embryos.
A pro-tumor environment in the cell can encourage a gene to produce an alternative form of RNA that enables cancer to spread, report researchers at the Medical University of South Carolina in Nature Cell Biology.
