      As Demand for African Timber Soars, Birds Pay the Ultimate Price

      September 08, 2015

      A new study co-authored by scientists at Drexel University, published in the most recent issue of Biological Conservation, reveals the devastating impact of illegal logging on bird communities in the understory layer of Ghana’s Upper Guinea rain forests, one of the world's 25 “biodiversity hotspots” where the most biologically rich ecosystems are most threatened.

      Thick Cortex Could Be Key in Down Syndrome

      June 19, 2015

      The thickness of the brain’s cerebral cortex could be a key to unlocking answers about intellectual development in youth with Down Syndrome, according to a new study led by a Drexel psychologist.

      Do Insect Societies Share Brain Power?

      June 17, 2015

      A new Drexel study suggests that social behavior evolved very differently in the brains of social insects than in vertebrate animals such as mammals, birds and fish.

      Underground Ants Can't Take the Heat

      June 15, 2015

      A new Drexel study shows underground species of army ants are much less tolerant of high temperatures than their aboveground relatives—and that could mean  climate change models lack a key element of how animal physiology could affect responses to changing environments.

    • Why Diet Apps Fail

      May 07, 2015

      It’s actually not complicated at all. The reason most smartphone diet apps fail has nothing to do with the diet, and little to do with the app. A team of Drexel researchers is working on a solution to the real problem: getting people to stick to their diets.

    • Has Car Culture Crashed?

      May 06, 2015

      It’s been roughly a century since we were introduced to automobiles. But, as Americans buy fewer cars, drive less and get fewer licenses as each year goes by, it’s impossible not to wonder: has America passed its driving peak?

    • Asteroid Crash Kicked Off Mega-Volcano in the Process that Killed Dinosaurs, According to New Study

      May 06, 2015

      When an enormous asteroid struck Earth 66 million years ago, a planet-wide quake shook the magma plumbing of a massive, active volcano—radically changing the style of volcanic eruption in one of the planet’s rarest, largest lava flows. This is the sequence of events supported by a new study published last week in the Geological Society of America Bulletin by a team of scientists, including Drexel University volcanologist Loÿc Vanderkluysen and led by geologists at UC Berkeley.

      Mapping Language in the Brain

      April 16, 2015

      Aphasia, an impairment of language that often happens after stroke or other brain injury, affects about 1 in 250 people, and can make it difficult to return to work and to maintain social relationships. A new study published in the journal Nature Communications provides a detailed brain map of language impairments in aphasia following stroke.

      A group of researchers at Drexel University, headed up by Michael Lowe, PhD, a clinical psychologist who studies the psychobiology of eating and weight regulation and a professor of psychology in Drexel’s College of Arts and Sciences, suggests that actual elevations in body mass during childhood may play a much bigger role in the development of disordered eating than previously thought.

      Mapping Perceptions of Environmental Health Risks: A Comparison of Three Philadelphia Communities

      January 27, 2015

      This past fall, Drexel researchers from the Center for Science, Technology, and Society, and the School of Public Health, in collaboration with the Clean Air Council, conducted a community survey that investigated how River Ward residents perceive environmental conditions in their neighborhood, how residents obtain information about hazards as well as community projects, and what they thought were priority issues for the River Wards district. The study, “Mapping Perceptions of Environmental Health Risks,” was funded by Drexel’s Social Science Council, which solicited applications for interdisciplinary projects that paired social scientists with faculty from other disciplines.

    • A Year of Finding New Life on This Planet

      January 06, 2015

      In most year-in-review posts, the Drexel News Blog takes the opportunity to reflect on experiences and stories, both local and global, that they took note of over the past 12 months. But this one is about new finds that you might not have heard about - and it's remarkable how unremarked such things can be. Every month of every year, scientists continue to add pages to the catalog of life on Earth, discovering and documenting new species from the swimming to the squirmy to the photosynthetic and microscopically beautiful.
