A Tiny, Toothy Catfish with Bulldog Snout Defies Classification

Kryptoglanis shajii is a strange fish — and the closer scientists look, the stranger it gets. This small subterranean catfish sees the light of day and human observers only rarely, when it turns up in springs, wells and flooded rice paddies in the Western Ghats mountain region of Kerala, India. Scientists at the Academy of Natural Sciences of Drexel University have recently provided a detailed description of this fish's bizarre bone structures.

Witnesses to Hunger Photo Exhibit Returns to Boston City Hall

Mothers caring for young children on limited incomes, who are part of the groundbreaking “Witnesses to Hunger” program, will reunite for a photo exhibit and events at Boston’s City Hall this May. They will participate in vital discussions addressing the health impacts of poverty and on critical issues affecting mothers and children in commemoration of Mother’s Day.

Child's Autism Risk Accelerates with Mother's Age Over 30

A recent study from researchers from the Drexel University School of Public Health in Philadelphia and Karolinska Institute in Sweden provides more insight into how the higher risk of having a child with an autism spectrum disorder (ASD) among older parents varies between mothers’ and fathers’ ages, and found that the risk of having a child with both ASD and intellectual disability is larger for older parents.

Tianna, a participant in Witnesses to Hunger, reviews some of the program's accomplishments with her children at the program's five-year anniversary exhibit.

Witnesses to Hunger Photo Exhibit on Capitol Hill

“Witnesses to Hunger,” a groundbreaking project featuring the voices and photography of parents and caregivers who have experienced hunger and poverty first-hand, is returning to the nation’s capital on April 3 and 4.

The two partial limb fossils from the ancient sea turtle <i>Atlantochelys mortoni</i> fit together perfectly, leaving little room for doubt that they are from the same bone. This discovery surprised paleontologists because the two halves were discovered at least 163 years apart, defying conventional wisdom that most fossils break down after weeks or months of surface exposure.

Two Fossils From Same Bone, Discovered 162 Years Apart, Fit Together 'Like Puzzle Pieces'

To the surprise of paleontologists from the Academy of Natural Sciences of Drexel University and the New Jersey State Museum, two halves of a turtle bone, discovered 162 years apart, fit together perfectly. The discovery provides new insight into one of the largest turtle species that ever lived.

11th Street Health Center to Expand With Sheller Gift to Meet the Future of Primary Health Care

Drexel University will begin a major expansion of its nurse-managed health center which is nationally recognized as a model of integrated care. With a new gift of $2.5 million from the Sheller Family Foundation, the center at 850 N. 11th Street will break ground for a new wing this spring, with the expanded building to be renamed the Stephen and Sandra Sheller 11th Street Family Health Services Center.

Drexel Program Participant Tianna Gaines-Turner Gets a Seat at the State of the Union

Tianna Gaines-Turner, a low-income mother of three children from North Philadelphia, will attend the State of the Union address as a guest of Pennsylvania Senator Bob Casey on Jan. 28, the Senator announced today. Her attendance marks a new achievement of a Drexel program raising the voices of families living in poverty to gain a place in the national conversation.

Fossil Find Shows Fish Hips Grew Strong Before Life's First Steps

The discovery of new fossil materials from the ancient fish species Tiktaalik roseae has revealed a key link in the evolution of hind limbs. The newly described, well-preserved pelves and partial pelvic fin from this 375 million-year-old transitional species between fish and the first legged animals, reveals that the evolution of hind legs actually began as enhanced hind fins, contrary to the existing theory that large hind legs developed after vertebrates transitioned to land.

Paperwasps in Different Castes Develop Different-Sized Sensory Brain Structures

A queen in a paperwasp colony largely stays in the dark. The worker wasps, who fly outside to seek food and building materials, see much more of the world around them. A new study led by Drexel professor Sean O'Donnell, PhD, indicates that the brain regions involved in sensory perception also develop differently in these castes, according to the different behavioral reliance on the senses.

“Witnesses to Hunger” Program Marks Five-Year Anniversary with Photo Exhibit at Drexel

Since 2008, the “Witnesses to Hunger” program at the Drexel University School of Public Health has sought to bring the true experts — those with first-hand experience — into the conversation about hunger and poverty by equipping caregivers of young children with digital cameras to document hunger and poverty.

Foreground: Dr. Tracy Quirk uses a Surface Elevation Table (SET) to measure relative sediment elevation change in a salt marsh in Barnegat Bay, NJ while staff scientist Linda Zaoudeh records data. Background: Staff scientist Stephanie Leach and Drexel environmental science graduate student Viktoria Unger use Real Time Kinematic (RTK) satellite navigation with GPS technology to measure the elevation of the marsh.

Drexel Scientist Studies Hurricane Sandy Impact on NJ Coastal Wetlands One Year Later

In a stroke of good luck, Drexel's Dr. Tracy Quirk captured detailed measurements of water level and salinity at a range of coastal wetland sites, even as they were overtaken by Hurricane Sandy. After the storm, she began working on an intensive year-long project, funded by the National Science Foundation, to evaluate ecosystem processes in New Jersey’s salt marshes before, during, and for a year following Hurricane Sandy. Quirk is beginning to analyze findings from the study now.

Drexel Study Shows Longline Fishery in Costa Rica Kills Thousands of Sea Turtles and Sharks

The second-most-common catch on Costa Rica’s longline fisheries in the last decade was not a commercial fish species. It was olive ridley sea turtles.
