A team of biochemists led by Caltech's André Hoelz has solved the architecture of the nuclear pore complex's complicated inner ring, a subcomplex that is central to the cellular machine's ability to serve as a barrier and transport facilitator. In the process, they disproved many previously held ideas about how the inner ring works.
A Florida State University engineering professor has developed a new highly efficient and low cost light emitting diode that could help spur more widespread adoption of the technology.
A University of Texas at El Paso study on children's health has found that fourth and fifth graders who are exposed to toxic air pollutants at home are more likely to have lower GPAs.
Queen's University developmental psychology professor Stanka Fitneva has co-authored a study in the journal Science that, for the first time, explores the replicability of psychology research.
Today, IADR/AADR published a Discovery! article titled '10 Years of a National Oral Health Policy in Brazil: Innovation, Boldness and Numerous Challenges.' In it, authors Gilberto Alfredo Pucca, Jr., Mariana Gabriel, Maria Ercilia de Araujo and Fernanda Campos Sousa de Almeida discuss Brazil's National Policy of Oral Health, also known as 'Smiling Brazil.'
A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope. The discovery of two supermassive black holes -- one larger one and a second, smaller one -- are evidence of a binary black hole and suggests that supermassive black holes assemble their masses through violent mergers.
The Global Precipitation Measurement or GPM core satellite has provided meteorologists with a look at the towering thunderstorms and heavy rainfall occurring in Tropical Storm Erika as it moves through the Caribbean Sea.
A University of Montana professor who studies birds around the world has discovered trends in how the offspring grow, how parents care for the young and how well the young survive based on where they live.
Fanxiu Zhu, the FSU Margaret and Mary Pfeiffer Endowed Professor for Cancer Research, and his team uncovered a viral protein in the cell that inhibits the major DNA sensor and thus the body's response to viral infection, suggesting that this cellular pathway could be manipulated to help a person fight infection, cancer or autoimmune diseases.
More than 15 million Americans live within one mile of unconventional oil and gas (UOG) operations that combine directional drilling and hydraulic fracturing, or 'fracking,' to release natural gas from underground rock. Researchers with the University of Missouri and national colleagues have reviewed research on health effects associated with UOG operations and concluded these activities have potential for environmental release of a complex mixture of endocrine disrupting chemicals that could potentially harm human development.
