In the second grade, Kelsey Moore became acquainted with geologic time. Her teachers instructed the class to unroll a giant strip of felt down a long hallway in the school. Most of the felt was solid black, but at the very end, the students caught a glimpse of red.

The amount of water used per well for hydraulic fracturing surged by up to 770 percent between 2011 and 2016 in all major U.S. shale gas and oil production regions, a new Duke University study finds.

It may seem off-putting to some, but human waste is full of nutrients that can be recycled into valuable products that could promote agricultural sustainability and better economic independence for some developing countries.

A few little cells that are different from the rest can have a big effect. For example, individual cancer cells may be resistant to a specific chemotherapy—causing a relapse in a patient who would otherwise be cured. In the journal Angewandte Chemie, scientists have now introduced a microfluidics-based chip for the manipulation and subsequent nucleic-acid analysis of individual cells. The technique uses local electric fields to highly efficiently “trap” the cells (dielectrophoresis).

A new research study published in the journal Invasive Plant Science and Management tackles those questions and provides insights that can benefit land managers.

Methane released by thawing permafrost from some Arctic lakes could significantly accelerate climate change, according to a new University of Alaska Fairbanks-led study.

FINDINGS
In the first study of its kind, researchers have found that cholesterol-lowering statins may improve the conditions of people with a rare lung disease called autoimmune pulmonary alveolar proteinosis. The research also suggested that two new tests could help diagnose the condition.

A first-of-its-kind global study shows that children in 27 developing countries have better nutrition--when they live near forests.

A University of Saskatchewan (U of S)-led research team has played a key role in an international discovery that will have an impact on the food security of millions of people around the world—the sequencing of the billion-piece jigsaw puzzle that is the bread wheat genome.

By sequencing the genome of the yellow-banded bumblebee, York University researchers have found that inbreeding and disease are likely culprits in their rapid decline in North America.
