The California condor was one of the first species to be listed under the Endangered Species Preservation Act in 1966 when the population was reduced to a handful of birds.
Through a massive collaborative effort that included fieldwork and breeding in zoos, the condor population has grown to more than 400 birds, more than half of which are now free-flying in the wild.
Unfortunately, there is overwhelming evidence that lead poisoning from accidental ingestion of spent ammunition is the leading cause of death in the wild population, and this may prevent the establishment of self-sustaining populations.
"After reviewing nearly 20 years of our mortality data on the free-ranging birds, it became clear that lead poisoning is the primary problem for the birds in the wild. And this is not just a problem for California condors.
We can view them as an indicator species, warning us about the hazards of widespread lead contamination in the environment." said Bruce Rideout, director of the wildlife disease laboratories for San Diego Zoo Global.
Our collaborators at the Wildlife Health Center at the School of Veterinary Medicine, University of California at Davis recently published a review of the impact of lead in ammunition on scavenging birds and what it means for the health of our shared environment. The review article can be found in the January edition of the journal EcoHealth.
Bringing species back from the brink of extinction is the goal of San Diego Zoo Global. As a leader in conservation, the work of San Diego Zoo Global includes onsite wildlife conservation efforts (representing both plants and animals) at the San Diego Zoo, San Diego Zoo Safari Park, and San Diego Zoo Institute for Conservation Research, as well as international field programs on six continents.
The important conservation and science work of these entities is made possible by the San Diego Zoo Global Wildlife Conservancy and is supported in part by the Foundation of San Diego Zoo Global.

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.
RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...
Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.
To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
