      Can’t Switch Your Focus? Your Brain Might Not Be Wired for It

      December 19, 2017

      A new study suggests that the extent to which brain signals “stick” to white matter networks is associated with cognitive flexibility, or our ability to switch our focus from one concept to another.

      Dolan Fund for Innovative Water Research

      December 19, 2017

      Water scarcity is one of the greatest challenges of our time, according to the United Nations. For the Dolan family of Philadelphia, water runs deep and personal. Almost 90 years ago, Philadelphia-area naturalist/adventurist, Brooke Dolan II, led expeditions to western China and Tibet and collected the Asian mammals on exhibit in the dioramas of the Academy of Natural Sciences of Drexel University. He and his colleagues also brought back thousands of other specimens to study at a time when the world looked to natural history museums for information on countless little-known species.

At the time of their meeting, Lombardo had just graduated from Duke University with her master’s in physical therapy. “I knew if I could get him up on the parallel bars, he’d be able to walk,” she says, “and I could teach him how to transfer in and out of his wheelchair.” She considers that day a sign of her true purpose in life. Soon after, she applied to doctoral programs in clinical psychology and chose Drexel’s program (formerly part of Hahnemann University) because of its location and because of Arthur Nezu, PhD, one of the program’s directors, with whom she interviewed.

      ‘Who Needs a Flu Shot? – Not Me’

      February 08, 2017

      “There has been a little flu, but there will be more…we have not seen the worst of it, flu usually peaks in February,” said an article in The Philadelphia Inquirer in January. Now in February, we think – people better get their flu shots, take vitamin C and heed the public health cautions plastered across the news media. But what impact do these public health messages actually have on us? Are we going to race out and get our flu shot? According to a Drexel University communication researcher, probably not. And it’s not because we think we’re invincible, it’s because we like to think we’re immune to the influences of messages in the mass media — a communications theory termed the “third-person effect.”

Cancer cells gobble up fluid and particles by a process termed macropinocytosis, which is the internalization of extracellular material by cell membrane ruffles that close into organelles known as macropinosomes.

      August 22, 2016

      Strict “zero tolerance” policies have led to a disturbing number of in-school arrests — about 1,600 in the School District of Philadelphia annually. Once in the justice system, youths’ life chances are diminished considerably. Psychology Professor Naomi Goldstein is working with community partners to divert students from the damaging “school-to-prison pipeline,” improving outcomes for youth and making Philadelphia a national leader in the process.

      University research typically is a fairly insular endeavor, played out at the department level with little cross-pollination among the various disciplines. Senior Vice Provost for Research Aleister Saunders is trying to widen that view. He has been advocating a university-wide approach to research, looking for those areas where Drexel can support and encourage investigations that cut across departments and disciplines.

      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.

    • 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.

      Paleontologists Assemble Giant Turtle Bone from Fossil Discoveries Made Centuries Apart

      March 25, 2014

      To the surprise of paleontologists, two halves of a turtle bone fit together perfectly, like puzzle pieces. The discovery linked scientists from the Academy of Natural Sciences of Drexel University and the New Jersey State Museum with their predecessors from the 19th century, while providing new insight into one of the largest turtle species that ever lived.

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

      January 13, 2014

      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.

    • GPS Traffic Maps for Leatherback Turtles Show Hotspots to Prevent Accidental Fishing Deaths

      January 08, 2014

      The leatherback turtle in the Pacific Ocean is one of the most endangered animals in the world. Its population has declined by more than 90 percent since 1980. One of the greatest sources of mortality is industrial longlines that set thousands of hooks in the ocean to catch fish, but sometimes catch sea turtles as well. Using modern GPS technology, researchers are now able to predict where fisheries and turtles will interact and to reduce the unwanted capture of turtles by fishermen.

    • Paperwasps in Different Castes Develop Different-Sized Sensory Brain Structures

      January 06, 2014

      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.

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

      September 29, 2011

      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.
