The Thinker

_Dimetrodon Discovery

_Ted Daeschler

A prehistoric fossil is “discovered” in the University’s collections and finally classified with its close relatives, 160 years after being dug out of the ground.

_What Really Killed Them?

_Loÿc Vanderkluysen

A new theory suggests that the dinosaurs’ fate was sealed by not just one, but two separate disasters around 66 million years ago.

_Natural-born Mysteries

A catfish, a diatom and a previously uncatalogued Cambodian plant were among the new species written into the scientific record this year.

_Game of Fonts

_Rajneesh Suri

A study of consumer behavior has found that shoppers are more drawn to sales prices when they are displayed in a hard-to-read font.

_Breathing Life Back Into Brooktrout Lake

_Frank Acker AND TEAM

A group of ecologists prove that recovery is possible for lake ecosystems devastated by acid rain — and that clean air regulations do work.

_Asthma-autism Link

_Nicole Gidaya

Prenatal exposure to anti-asthma drugs is associated with increased risk for autism.

_Binary Blackboards

_Aroutis N. Foster

Video games aren’t just for recreation; when brought into the classroom they can help students discover their destiny.

_Body, Heal Thyself

_Kara Spiller

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

_A Down-Alzheimer’s Connection

_Nancy Raitano Lee

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.

_Gut Reaction

_Michael Lowe AND TEAM

The way to a woman’s heart is through her stomach, a new study shows.

_Hidden in Plain Site

_Nazanin Andalibi

The anonymity of online forums may be a unique source of support, guidance and healing for survivors of sexual abuse.

_Atomic Sandwiches

_Babak Anasori

Drexel engineers’ recipe for ‘sandwiching’ atomic layers expands the possibilities for making materials that store energy.

_Science Underfoot

_Ted Daeschler

The Academy of Natural Sciences of Drexel University celebrated the 200th anniversary of the geological map that laid the foundation for earth science with a rare public viewing this year.

_The $150 Billion Problem

_meghan Butryn

A multidisciplinary team is developing ways to battle the obesity epidemic by helping people lose weight and keep it off.

_Tiny Switch

_jonathan e. spanier

A bit of residual moisture helped researchers unlock the ultraviolet light-emitting potential of a material they were studying.

_Stem Cell Algorithm

_Andrew Cohen

Using image-tracking technology, Drexel scientists observe nature vs. nurture in neural stem cells — information that could lead to breakthroughs in regenerative medicine.

_A Step Toward Solving PKU

_Emilia Arturo

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.

_Different Kind of Crystal Ball

_Christopher Li

A new method has been discovered for growing spherical crystals that could be used for drug delivery.

_Nature’s Filter

_chris sales

Algae scooped from an urban fish pond are the slimy secret ingredients in a bioreactor that Drexel environmental engineers say is more effective at treating wastewater than many processes employed in city treatment facilities today.

_Driven to Distraction

_Erin T. Solovey

Bodies release telltale signals when we’re distracted, bored or stressed, and it may be possible to use that information to build adaptive technologies.

_Stem Cell ‘Legos’

_Wei Sun

Using a custom-designed 3-D printer, an engineer has devised a way to manufacture the building blocks of life.

_Chip Combo

_Yury Gogotsi

A new process has been discovered that will make it possible to combine micro-scale batteries with a microchip, opening the door to ever-more-compact personal electronics.

_The Great Disconnect

_Neeta Fogg

Too many Philadelphia youth are disconnected from school and work at a crucial juncture in their lives, a Drexel study found.

_Parental Blues & Poor Grades

_Félice Lê-Scherban AND TEAM

There’s a connection between depression in parents and poor academic performance by their children.

_Plaque Bust

_Carol F. Lippa

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

_A Home Base

_James E. Connell Jr.

A virtual “home” for the behavioral health needs of children and young adults on the autism spectrum aims to provide better outcomes at a lower cost.

_Improving the Picture

_Wan Shih AND TEAM

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.

_The Secret Life of Ebola

_Charles Haas

The discovery that the Ebola virus can survive longer in wastewater than was previously known has implications for how governments respond to outbreaks.

_The Breaking Point

_Leslie Lamberson

Inside her custom-designed lab, Leslie Lamberson smashes, cracks and pushes materials to better understand, and extend, their limits.

_Fumes and Plumes

_Longjian Liu

Drexel researchers found a significant link between elevated air pollution and the occurrence of several chronic health conditions.

_Varsity Blues

_Eugene Hong

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.

_The VC-CEO Dynamic

_H. Dennis Park AND TEAM

Startups should be aware that the more power they assign to their CEO, the more risk the chief could be willing to take on, especially in the beginning.

_When Rubber Hits the Road

_Yury Gogotsi
