A sophisticated mechanism that allows plant roots to quickly respond to changes in soil conditions has been identified by an international research team.
Researchers from North Carolina State University have developed a high-throughput technique that can determine if a chemical has the potential to activate key genes in seconds rather than the typical 24 hours or more. The technique can be used to prioritize chemicals for in-depth testing to determine their toxicity.
Researchers from Sanford Burnham Prebys Medical Discovery Institute, the Cardiovascular Institute at Stanford University and other institutions were surprised to discover that the four genes in the Id family play a crucial role in heart development, telling undifferentiated stem cells to form heart tubes and eventually muscle.
Female teenagers living in neighbourhoods with wide salary gaps and a low-income household show changes to their brain maturation that could indicate a higher risk of developing mental illness in adulthood, suggests a recently published study by Canadian researchers.
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.
Female patients with locally advanced esophageal cancer that is treated with chemotherapy and radiation therapy before surgery are more likely to have a favorable response to the treatment than male patients are, and women are less likely to experience cancer recurrence, according to a study published online today in The Annals of Thoracic Surgery.
ETH Zurich researchers have identified all the genes required by a bacterium to use methanol as a food source. The results will help scientists advance the use of this resource in the field of biotechnology.
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 discovery in lab mice that an 'anti-sense' RNA is expressed after nerve injury to regulate the repair of damage to the nerve's myelin coating could lead to a treatment that improves healing in people.
Researchers have revealed the existence of a new quorum-sensing molecule that increases the virulence of the pathogenic bacterium Pseudomonas aeruginosa.
