Lynne E. Maquat and her team identified a novel pathway for regulating RNA degradation, called Staufen1-mediated degradation (SMD). This mechanism affects numerous transcripts and is a new form of gene regulation. SMD activity may be regulated by cell signaling pathways.
A defect in neuroligin genes disrupts neuronal connections and results in an imbalance of neuronal function, providing a possible explanation for autistic children's neurodevelopmental defects. Understanding this cellular defect is crucial towards developing therapies for autism-spectrum disorders.
Researchers at UT Southwestern Medical Center successfully implemented Universal Newborn Hearing Screening, reducing the number of false positives and increasing follow-up rates. Rescreening infants four hours after birth improved outcomes, while providing outpatient retesting encouraged parents to return for further evaluation.
A new Stanford study has found that self-identified racial and ethnic groups correlate strongly with their genetic profiles, with an error rate of less than 0.14%. The research, involving 3,636 participants, challenges the idea that race is a social construct with no genetic basis.
The ARM Mobile Facility is a moveable, atmospheric-measuring suite designed to withstand temperatures from minus-40 to plus-120 degrees Fahrenheit. The station measures physical properties of air and heat radiating from clouds and the ground, providing critical information missing in climate models.
Scientists at Ohio State University have found that a long-ago ice age occurred 10 million years earlier than previously thought. The discovery resolves an inconsistency in climate change research and suggests that CO2 concentrations drive climate. Sea levels may have been low globally at the time, likely due to a global ice buildup.
A new study from the University of Pennsylvania School of Medicine suggests that PPARã can turn genes both on and off. By targeting this ability to turn off genes without affecting others, researchers may develop drugs called SPPARMs that decrease TZD-related side effects.
A study of 150 subjects found that listening to a relaxation tape prior to and during mammography did not decrease women's feelings of pain and anxiety. In fact, virtually none of the participants experienced pain or anxiety during the test, contradicting previous studies that attributed non-compliance to pain.
A large study found that early surgery does not reduce deaths and disability in patients with brain hemorrhage. Only patients with small blood clots near the surface of the brain may benefit from surgical intervention.
