The Brittleness of Aging Bones – More than a Loss of Bone Mass

*Berkeley Lab Researchers Show How Loss of Bone Quality Also a Major Factor*

It is a well-established fact that as we grow older our bones become more brittle and prone to fracturing. It is also well established that loss of mass is a major reason for older bones fracturing more readily than younger bones, hence medical treatments have focused on slowing down this loss. However, new research from scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) shows that at microscopic dimensions, the age-related loss of bone quality can be every bit as important as the loss of quantity in the susceptibility of bone to fracturing.

PASADENA, Calif. –– NASA is giving the public the power to journey through the solar system using a new interactive Web-based tool.

The “Eyes on the Solar System” interface combines video game technology and NASA data to create an environment for users to ride along with agency spacecraft and explore the cosmos. Screen graphics and information such as planet locations and spacecraft maneuvers use actual space mission data. (more…)

*Water significant limiting factor in growing crops like switchgrass*

Energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn.

They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.

“While we are looking for solutions for energy through bioenergy crops, dependence on water gets ignored, and water can be a significant limiting factor,” said Praveen Kumar, an environmental engineer and atmospheric scientist at the University of Illinois at Urbana-Champaign. (more…)

MU study finds executives with shared responsibilities succeed and provide value to shareholders

COLUMBIA, Mo. – Many believe that two corporate heads are not better than one. However, a University of Missouri researcher has found that more companies have co-CEOs than previously though and that having two people in the senior leadership position is actually very successful for businesses.

Innovation Served on a Napkin: How GTRI Moved a Simple Idea From Inspiration to Fabrication

A ground-breaking innovation, birthed in a sudden flash of insight, is the stuff of legend. Air conditioning, Kevlar, the DNA-replicating process known as PCR (polymerase chain reaction) — each was the product of a Eureka! moment. The list may soon be longer by one, thanks to a wandering mind and a napkin.

When Jud Ready attended an academic conference on materials science in Boston in 2003, he didn’t plan on coming home with the idea for a three-dimensional solar cell, but that’s what happened. (more…)

PASADENA, Calif. – NASA’s Aquarius instrument has successfully completed its commissioning phase and is now “tasting” the saltiness of Earth’s ocean surface, making measurements from its perch in near-polar orbit. (more…)

Yale Establishes Kissinger Archives and the Johnson Center for the Study of American Diplomacy

Former secretary of state Henry A. Kissinger gave an address before Yale faculty, students and World Fellows during a ceremony to celebrate the establishment of the Kissinger archives and the Johnson Center for the Study of American Diplomacy.

The archives extend well beyond Kissinger’s years in the White House and span the nearly 40 years since he left public service. Kissinger’s papers will serve as the foundation for the newly created Johnson Center, made possible by generous contributions from Charles B. Johnson ’54 B.A. and Nicholas F. Brady ’52 B.A. The Center will be located within the Jackson Institute for Global Affairs at Yale. (more…)

Mission Possible or Impossible? UA Space Systems Engineer Has the Answer

Scientists have endless ideas for extraterrestrial exploration. Some are feasible, some not. In a two-part series, we look at how UA engineer Roberto Furfaro gives the red or green light to space missions. First, searching for Delta-V, the complex factor that makes a space mission viable

Our solar system is becoming a familiar backyard, thanks to the University of Arizona’s Lunar and Planetary Laboratory, or LPL, a world leader in interplanetary exploration. (more…)
