*Growth of cropland, loss of natural habitat to blame*
The continued growth of cropland and loss of natural habitat have increasingly simplified agricultural landscapes in the Midwest.
In a study supported in part by the National Science Foundation’s (NSF) Kellogg Biological Station Long-Term Ecological Research (LTER) site in Michigan–one of 26 such NSF LTER sites around the world–scientists concluded that this simplification is associated with increased crop pest abundance and insecticide use.

AUSTIN, Texas — Current and proposed border fences pose significant threats to wildlife populations, with those animals living in border regions along the Texas Gulf and California coasts showing some of the greatest vulnerability, a new study from The University of Texas at Austin shows.
“Our study is the first comprehensive analysis of threats to species across the entire U.S.-Mexico border,” says Jesse Lasky, a graduate student in the laboratory of Tim Keitt, associate professor of integrative biology. “The scale at which these fences stretch across the landscape is large, so it’s important for us to also have a large-scale view of their effects across the continent.” (more…)
*Google Health users can send their Google Health profile directly to a HealthVault account using Direct Project messaging protocols.*
REDMOND, Wash. — July 18, 2011 — Microsoft Corp. today announced that people using the Google Health service, scheduled to be discontinued Jan. 1, 2012, can easily transfer their personal health information stored in a Google Health profile to a Microsoft HealthVault account using the Direct Project messaging protocols established by the Office of the National Coordinator for Health IT. The Direct Project specifies a simple, scalable, standards-based way for participants to send authenticated, encrypted health information to known, trusted recipients over the Internet.
Google announced on June 24 that Google Health will be discontinued, effective Jan. 1, 2012, with records remaining available to account holders until Jan. 1, 2013. (more…)
*Smartphone Adoption Leads to Doubling of Map App Audience*
RESTON, VA, July 18, 2011 – comScore, Inc., a leader in measuring the digital world, today released results of a U.S. study of mobile map usage based on data from its comScore MobiLens service. The study found that 48 million mobile users accessed maps on their mobile device during the three month average period ending May 2011, an increase of 39 percent from the previous year, driven in large part by the increase in smartphone adoption. The study found that map usage via mobile applications was the primary access point for smartphone owners as the map app audience doubled in size over the past year. (more…)
COLUMBIA, Mo. – According to the Centers for Disease Control and Prevention, 1.7 million people suffer traumatic brain injuries each year. Stephanie Reid-Arndt, chair and assistant professor of health psychology in the University of Missouri School of Health Professions, has launched The Brain Injury Guide and Resources at https:// braininjuryeducation.com/ to provide a resource for people to understand traumatic brain injuries.
“Brain injuries aren’t visible like other injuries, and often, people with brain injuries can be misunderstood,” Reid-Arndt said. “Direct results of a traumatic brain injury (TBI) include cognitive difficulties, changes in behavior or difficulty managing anger that are direct results of the brain injuries. Unfortunately, these symptoms are often misconstrued as willfully uncooperative behavior.” (more…)
Berkeley Lab scientists join their KamLAND colleagues to measure the radioactive sources of Earth’s heat flow
What spreads the sea floors and moves the continents? What melts iron in the outer core and enables the Earth’s magnetic field? Heat. Geologists have used temperature measurements from more than 20,000 boreholes around the world to estimate that some 44 terawatts (44 trillion watts) of heat continually flow from Earth’s interior into space. Where does it come from?(more…)
*Inhibiting a molecular process cells use to direct proteins to their proper destinations causes more than 90 percent of affected mosquitoes to die within 48 hours of blood feeding, a UA team of biochemists found.*
Mosquitoes die soon after a blood meal if certain protein components are experimentally disrupted, a team of biochemists at the University of Arizona has discovered.
The approach could be used as an additional strategy in the worldwide effort to curb mosquito-borne diseases like dengue fever, yellow fever and malaria. (more…)
PASADENA, Calif. — NASA’s Dawn spacecraft on Saturday became the first probe ever to enter orbit around an object in the main asteroid belt between Mars and Jupiter.
Dawn will study the asteroid, named Vesta, for a year before departing for a second destination, a dwarf planet named Ceres, in July 2012. Observations will provide unprecedented data to help scientists understand the earliest chapter of our solar system. The data also will help pave the way for future human space missions. (more…)
