CHAPEL HILL - Across North Carolina, the risk of death from the most common form of acute leukemia in adults was significantly higher in three regions, researchers from the University of North Carolina Lineberger Comprehensive Cancer Center found.

In a retrospective study published in the journal Cancer, researchers report that adults treated with chemotherapy in the hospital for acute myeloid leukemia, or AML, between 2003 to 2009 had a statistically significant higher risk of death if they lived in northeastern North Carolina from Wilson to Roanoke Rapids, in a region around Greenville, and a region around Wake County, including Durham County. Those differences remained even after researchers controlled for other factors that might help drive the increases.

BOSTON (June 28, 2016)--Researchers at Tufts University School of Dental Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts, led by Jonathan Garlick, have established for the first time that skin cells from diabetic foot ulcers can be reprogrammed to acquire properties of embryonic-like cells. These induced pluripotent stem cells might someday be used to treat chronic wounds. The study is published online in advance of print in Cellular Reprogramming.

A second study from the research team published in Wound Repair and Regeneration found that a protein called fibronectin is linked to a break-down in the wound-healing process in cells from diabetic foot ulcers.

This new image from the NASA/ESA Hubble Space Telescope shows a cosmic tadpole, with its bright head and elongated tail, wriggling through the inky black pool of space. Tadpole galaxies are rare and difficult to find in the local Universe. This striking example, named LEDA 36252, was explored as part of a Hubble study into their mysterious properties -- with interesting results.

This week is National Mosquito Control Awareness Week, and the Entomological Society of America is supporting the effort with a special collection of articles about the Asian tiger mosquito.

How do the cells in a human embryo know where they are located in the body and how they should develop? Why do certain cells form a finger while others do not? Freiburg biologists have explained the mechanisms that control these steps by showing why veins form at particular points in the wing of a fruit fly. The protein Pentagone spreads a particular signal in the wing that tells the cells how to behave. "The proteins Dpp and Pentagone, which are crucial for this developmental step in the organism Drosophila melanogaster, are also present in a similar form in humans," says the Freiburg biologist Dr. Giorgos Pyrowolakis.

Pipelines carrying crude oil to ports in British Columbia may spell bad news for salmon, according to a new University of Guelph-led study.

Exposure to an oil sands product - diluted bitumen - impairs the swimming ability and changes the heart structures of young salmon.

The research will be published in the journal Environmental Toxicology and Chemistry, and is available online now.

It's a timely finding, says U of G post-doctoral researcher and lead author Sarah Alderman.

The National Energy Board (NEB) recently approved the controversial Trans Mountain pipeline expansion project; the federal government is expected to make a final decision by December.
