COLUMBIA, Mo. – Parents are often amazed at how fast their child grows and develops. New research at the University of Missouri has determined that the ability to quantify – even things that are hard to quantify, such as liquid – may develop much sooner than most parents realize.

University of Missouri researcher Kristy vanMarle, an assistant professor in the Department of Psychological Sciences in the College of Arts and Science, has determined that contrary to what previous studies have shown, infants are able to quantify non-cohesive substances – like sand, water, or even Cheerios – as early as 10 months. As long as the difference between the two substances is large enough, vanMarle has found that infants will choose the larger amount, especially when it comes to food. (more…)

The National Science Foundation has signed a five-year, $34.5-million agreement with the University of Wisconsin-Madison to operate a unique telescope–a cubic kilometer in volume–buried in the Antarctic ice sheet between 1,400 meters and 2,400 meters deep.

The collaborative agreement covers the cost of operating the IceCube Neutrino Observatory, located in the ice under the U.S. Amundsen-Scott South Pole Station. The observatory records the rare collisions of neutrinos, elusive sub-atomic particles, with the atomic nuclei of the water frozen into ice. Neutrinos come from the sun, cosmic rays interacting with the Earth’s atmosphere, and dramatic astronomical sources such as exploding stars in the Milky Way and other distant galaxies. Trillions of neutrinos stream through the human body at any given moment, but they rarely interact with regular matter, and researchers want to know more about them and where they come from. (more…)

Most River Flows across the U.S. are Altered by Land and Water Management, Leading to Ecological Degradation

The amount of water flowing in streams and rivers has been significantly altered in nearly 90 percent of waters that were assessed in a new nationwide USGS study. Flow alterations are a primary contributor to degraded river ecosystems and loss of native species.

“This USGS assessment provides the most geographically extensive analysis to date of stream flow alteration,” said Bill Werkheiser, USGS Associate Director for Water. “Findings show the pervasiveness of stream flow alteration resulting from land and water management, the significant impact of altered stream flow on aquatic organisms, and the importance of considering this factor for sustaining and restoring the health of the Nation’s streams and ecosystems.” (more…)
