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 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.
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.
Collisions with wind turbines kill about 100 golden eagles a year in some locations, but a new study that maps both potential wind-power sites and nesting patterns of the birds reveals sweet spots, where potential for wind power is greatest with a lower threat to nesting eagles.
Berkeley Lab researchers have incorporated molecules of porphyrin CO2 catalysts into the sponge-like crystals of covalent organic frameworks (COFs) to create a molecular system that not only absorbs carbon dioxide, but also selectively reduces it to CO, a primary building block for a wide range of chemical products.
WHRC scientists have counseled the State Department on policies that could control permafrost thaw, including reducing global carbon emissions from fossil fuel use and deforestation, and limiting emissions of 'black carbon,' sooty particles that darken snow and ice and hasten Arctic warming.
Research may lead to reevaluation of the current understanding of information flow and neural circuit maturation in the visual system.
Scientists from the Gladstone Institutes have discovered that HIV does not cause AIDS by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. In a new Cell Reports study, the researchers revealed that the HIV 'death pathway' -- how 95 percent of cells die from the virus -- is only initiated if the virus is passed from cell-to-cell, not if cells are infected by free-floating viral particles.
