Academy Scientists Receive Top Honors for Long-Term Research and Training Initiatives in Mongolia

Dr. Clyde Goulden, a pioneering ecologist and director of the Asia Center of the Academy of Natural Sciences of Drexel University, has devoted his life to studying climate change and how it is affecting Mongolian herders and the pristine 2-million-year-old Lake Hövsgöl. His efforts have now been recognized with Mongolia’s highest award to foreigners, the Order of the Polar Star. In a separate honor, Dr. Jon Gelhaus, Academy curator of entomology and professor in Drexel University’s College of Arts and Sciences, has received the Kublai Khan medal for his scientific achievements in Mongolia.

STEM Career Days to Inspire Philadelphia Public School Students at the Academy of Natural Sciences

Philadelphia public middle-school students and their teachers will be able to interact with scientists from FMC Corporation and explore learning and career opportunities in science and math thanks to a grant from the Philadelphia-based chemical company, the Academy of Natural Sciences of Drexel University announced today.

Researchers Describe the Physical Forces Underlying Sickle Cell Disease

Researchers at Drexel University have identified the physical forces in red blood cells and blood vessels underlying the painful symptoms of sickle cell disease. Their experiment, the first to answer a scientific question about sickle cell disease using microfluidics engineering methods, may help future researchers better determine who is at greatest risk of harm from the disease. They report their findings in Cell Press’s Biophysical Journal today.

Academy of Natural Sciences Joseph Leidy Award Goes to a Stony Brook Evolutionary Biologist

A leading evolutionary biologist whose textbooks on evolution are widely read by college students around the country will receive the prestigious Joseph Leidy Award, the Academy of Natural Sciences of Drexel University announced today.

Academy Celebrates Bugs in August With Nature's Assassins and Bug Fest

Dozens of live deadly scorpions, notorious black widow spiders, and giant centipedes will be on special display throughout August, as the Academy of Natural Sciences of Drexel University celebrates its Bicentennial with bug month. The creepy crawly experience really ratchets up Aug. 11 and 12 with the 5th annual Bug Fest celebration.

Long-Distance Distress Signal from Periphery of Injured Nerve Cells Begins with Locally Made Protein

New research recently published in Neuron, co-authored by Drexel's Dr. Jeffery Twiss, is one of the strongest indicators yet of molecular signaling from end to end in peripheral nerve cells. The team's new discoveries may help scientists better understand nerve cells' distress signals and nerve cell repair, so they can eventually control and enhance the process to speed up recovery from nerve injuries.

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.
