Sober Analysis

Should Philadelphians worry about the impact liquor privatization may have on public safety? For an answer, one researcher studied the data from Seattle's privatization in 2012, and it isn't pretty: More alcohol retailers is associated with more violence. _by Scott Pruden

Second Chances for First-Time Offenders

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. _by Tim Hyland / illustrations by Brian Stauffer

The Thinker

Drexel’s John Kounios and his collaborator were the first scientists to use brain scans to study how our minds make the leap from methodical thinking to sudden insight. In their new book, Kounios shares what they’ve learned about cultivating creativity. _by Lini S. Kadaba


In Ghana, over half of all forest understory birds have vanished in just 15 years as unchecked illegal logging, economic stress and demand for African timber take their toll on the nation’s rainforests. by Mike Unger

A biomedical engineer is investigating how to use the body’s own immune cells to grow blood vessels necessary to wound healing.

Improving the Picture

The same nanocrystals used to produce sharp images in liquid crystal display (LCD) televisions can be engineered to glow red when bonded to cancer cells — giving surgeons a rapid way to verify that they’ve removed all of a tumor.

Crystal Clear

X-ray crystallography is used to create three-dimensional models of molecules that help researchers understand how the molecules function within the body — knowledge that can be used to develop new antibiotics.

Varsity Blues

A large study of college athletes found that contrary to popular belief, jocks are just as likely to have down spells as the general population.

Plaque Bust

Drexel is leading a landmark investigation of a new drug that may prevent the plaque buildup thought to cause Alzheimer’s dementia.

A Down-Alzheimer’s Connection

Children with Down Syndrome have distinctive differences in the structure of their cerebral cortex that could help to explain the link between Down and Alzheimer’s.

One Cell, Many Roles

Specialized cells called astrocytes were once thought to be bit players in the central nervous system, but closer inspection suggests they have complex roles.

A Step Toward Solving PKU

For the first time, scientists have a model of the enzyme that is defective in patients with the metabolic disorder PKU — opening the door to new drug discovery.
