Naturally occurring arsenic in private wells threatens people in many US states and parts of Canada, according to a package of a dozen scientific papers to be published next week. The studies, focused mainly on New England but applicable elsewhere, say private wells present continuing risks due to almost nonexistent regulation in most states, homeowner inaction and inadequate mitigation measures.
To aid in the interpretation of CNVs, researchers have completed detailed maps of 184 duplications found in the genomes of individuals referred for genetic testing.
UT Southwestern Medical Center scientists have identified a strong link between the most aggressive type of breast cancer and a gene that regulates the body's natural cellular recycling process, called autophagy.
The close of the Permian Period around 250 million years ago saw Earth's biggest extinction ever. At this time large volcanic eruptions were occurring in what is now Siberia. The volcanoes pumped out gases that led to acid rain. Falling on the supercontinent Pangaea, the acid rain killed off end-Permian forests. The demise of forests led to soil erosion and the production of organic-rich sediments in shallow marine waters.
In a finding vital to effective species management, a team including City College of New York biologists has determined that the lined seahorse (Hippocampus erectus) is more a permanent resident of the western mid-Atlantic Ocean than a vagrant.
'Bio-molecular interaction analysis, a cornerstone of biomedical research, is traditionally accomplished using equipment that can cost hundreds of thousands of dollars,' said Wyss Associate Faculty member Wesley P. Wong, Ph.D., senior author of study. 'Rather than develop a new instrument, we've created a nanoscale tool made from strands of DNA that can detect and report how molecules behave, enabling biological measurements to be made by almost anyone, using only common and inexpensive laboratory reagents.'
Investigators have developed an analysis 'pipeline' that slashes the time it takes to search a person's genome for disease-causing variations from weeks to hours. An article describing the ultra-fast, highly scalable software was published in the latest issue of Genome Biology.
Research conducted at the LSU Health New Orleans Neuroscience Center of Excellence has discovered gene interactions that determine whether cells live or die in such conditions as age-related macular degeneration and ischemic stroke. These common molecular mechanisms in vision and brain integrity can prevent blindness and also promote recovery from a stroke.
Mussels could be the perfect 'sentinel' species to signal the health of coastal ecosystems. But a new study of blue mussels in estuary ecosystems along 600 kilometers of coastline in the Northeast uncovered three key mysteries that will have to be solved first.
Scientists led by the University of Edinburgh have identified a biological clock that provides vital clues about how long a person is likely to live.
