*Discovery may lead to novel biotech and nanotech uses*

Nevada, the “Silver State,” is well-known for mining precious metals.

But scientists Dennis Bazylinski and colleagues at the University of Nevada Las Vegas (UNLV) do a different type of mining.

They sluice through every water body they can find, looking for new forms of microbial magnetism.

In a basin named Badwater on the edge of Death Valley National Park, Bazylinski and researcher Christopher Lefèvre hit pay dirt. (more…)

Genetic Analysis Splits Desert Tortoise into Two Species

RIVERSIDE, Calif. – A new study shows that the desert tortoise, thought to be one species for the past 150 years, now includes two separate and distinct species, based on DNA evidence and biological and geographical distinctions.

This genetic evidence confirms previous suspicions, based on life history analysis, that tortoises west and east of the Colorado River are two separate species. (more…)

*Accelerates Advanced Intelligence for Smarter Buildings Transformation*

ARMONK, N.Y., – 14 Apr 2011: IBM today announced that it has completed the acquisition of TRIRIGA, Inc., a privately-held company based in Las Vegas, Nevada. Financial terms were not disclosed.

On March 22, IBM announced that it had entered into a definitive agreement to acquire TRIRIGA, a leading provider of facility and real estate management software solutions.

Many of the systems that constitute a building – heat, water, sewage, electricity and physical assets – are managed independently and often inefficiently. Collecting, managing and analyzing data in buildings provides actionable insight to energy, space and facilities management. (more…)

Uncertain Future for Joshua Trees Projected with Climate Change

FLAGSTAFF, Ariz. — Temperature increases resulting from climate change in the Southwest will likely eliminate Joshua trees from 90 percent of their current range in 60 to 90 years, according to a new study led by U.S. Geological Survey ecologist Ken Cole.

The research team used models of future climate, an analysis of the climatic tolerances of the species in its current range, and the fossil record to project the future distribution of Joshua trees. The study concludes that the species could be restricted to the northernmost portion of its current range as early as the end of this century. Additionally, the ability of Joshua trees to migrate via seed dispersal to more suitable climates may be severely limited. (more…)
