Private Landowners Can Help Protect Biodiversity "Arks" in Tropical Reserves

Many of the world’s tropical protected areas are struggling to sustain their biodiversity, according to a study just published in Nature by more than 200 scientists from around the world. Among them, Drexel's  Dr. Sean O’Donnell, highlighted the important, beneficial role of private landowners who work to preserve biodiversity in their land surrounding tropical reserves.

Rising Heat at the Beach Threatens Leatherback Sea Turtles, Climate Change Models Show

New research suggests that climate change could exacerbate existing threats to critically endangered leatherback turtles and nearly wipe out the population in the eastern Pacific. Deaths of turtle eggs and hatchlings in nests buried at hotter, drier beaches are the leading projected cause of the potential climate-related decline, according to a new study in the journal Nature Climate Change by a research team from Drexel, Princeton University, other institutions and government agencies.

El Niño Weather and Climate Change Threaten Survival of Baby Leatherback Sea Turtles

Drexel University researchers have found that the climate conditions at a major leatherback turtle nesting beach affects the early survival of turtle eggs and hatchlings. They predict, based on projections from multiple models, that egg and hatchling survival will drop by half in the next 100 years as a result of global climate change.

Study Identifies Pacific Danger Zones for Critically-Endangered Leatherback Sea Turtles

A major new study of migration patterns has identified danger zones in the Pacific Ocean for critically endangered leatherback sea turtles. This new understanding could help inform decisions about fishing practices to help reduce further deaths of this fragile species. Drexel University’s Dr. James Spotila was coordinator for the study involving collaborators worldwide.

A Zap of Cold Plasma Reduces Harmful Bacteria on Raw Chicken in Drexel Study

A new study by food safety researchers at Drexel University demonstrates that plasma can be an effective method for killing pathogens on uncooked poultry. The proof-of-concept study was published in the January issue of the Journal of Food Protection.

Academy of Natural Sciences Celebrates Bicentennial

The yearlong Bicentennial of the Academy of Natural Sciences of Drexel University will feature a major new exhibition opening March 24 called The Academy at 200: The Nature of Discovery. A special series of Town Square programs, some led by world-renowned experts, will focus on today’s critical environmental issues, and a science symposium will be held in the fall. For museum visitors, monthly themed activities, giveaways, and discounted admission days will provide fun and learning for the whole family.

Drexel Academy of Natural Sciences Complete Affiliation Agreement

The Academy of Natural Sciences President and CEO George W. Gephart, Jr., and Drexel University President John A. Fry, joined with Philadelphia Mayor Michael A. Nutter announced the completion of an historic affiliation between the Academy and Drexel that will promote discovery, learning and civic engagement in the natural and environmental sciences and further enhance Philadelphia’s reputation as a leader in scientific research and education.

Five-Story Biowall of Plants Serves as a Living Laboratory for Air Quality Research at Drexel

Drexel's new Papadakis Integrated Sciences Building features a five-story vertical wall of living plants – the largest such wall in North America and the only one at a U.S. university. Scientists and students at Drexel are studying the biowall, an active living filter that removes volatile organic compounds from the air, to get a better understanding of how it works.
