Memory loss, cognitive deficits, drops in IQ, and abnormal brain structures: these are but a few of the neurotoxic effects that recent research has correlated to marijuana use in adolescents. But while a number of studies suggest a link between these changes and regular cannabis use, particularly for young teens, there is no definitive evidence that marijuana is entirely to blame. Adolescents who smoke daily, for example, may have problems that predate marijuana use. One thing is certain: pot smoking among American teenagers is on the rise.

Even after Nick Foles threw 27 touchdown passes and two interceptions this season, even after he compiled the highest passer rating in the NFL, even after he led the Eagles to their first division title in three years to set up Saturday's wild-card matchup against the New Orleans Saints, there remains an air of mystery about him. This is understandable. It's not often that a quarterback selected in the third round of the NFL draft, as Foles was by the Eagles in 2012, flourishes as he has. It's even rarer that a quarterback with so humble a pedigree (by the standards of most elite NFL quarterbacks)

The scenes are too common for comfort: A mother grabs her daughter's arm roughly on the bus. A father at a Wawa growls coarsely into his son's ear. Not legally defined as child abuse, it's known as harsh or authoritarian parenting. Regardless of race or income level, mothers and fathers everywhere are capable of it. But low-income parents who struggle with stresses from overwhelming issues such as hunger, or lack of a job or adequate housing, seem to engage in harsh parenting more often, researchers have concluded.

Forget right-brain or left-brain thinking. What may be more important from a gender standpoint is back-to-front or side-to-side thinking. A new study from the University of Pennsylvania used diffusion tensor imaging, a type of brain imaging that shows how brain cells are connected, to study young men and women. The team's maps of major information highways were noticeably different for the two genders. Men had more pathways that ran the length of each hemisphere, to parts within a hemisphere and across the cerebellum, which coordinates movement.

She was supposed to be on her way to a neon-lit chapel where an Elvis impersonator waited to officiate at her wedding. Instead, the 27-year-old woman sat in a thin hospital gown on an examining table in a cold emergency room, anxiously waiting for news. A week before, she had gone to see her primary physician. She had been dealing with a series of strange symptoms over the summer. A curious, maddening itch. Achy joints from time to time. Vicious headaches that she supposed were like migraines, although she had never had them before.

'Mom, how long has this been going on?" the woman asked as she helped her 75-year-old mother back into bed. The woman had never seen her mother so unsteady on her feet. She walked as if drunk. "My left side feels so weak. I even have a hard time feeling my leg on that side," the mother said. "It started last night. " The daughter was alarmed on hearing her mother's slurred speech and learning how long the symptoms had been present. Worried that her mother might have suffered a stroke, she called 911. The responding EMTs shared her concern and rushed the elderly woman to the hospital.

It's a scene that might be repeated dozens of times on Drexel University's campus today: A student, sitting at a table, eating pizza. But Annie Feng is different. The sophomore nibbles on a mini pizza while wearing a headband designed to measure her brain activity. And unlike many brain-imaging machines, this device can be used at a table. By monitoring the brains of people during meals, researchers hope to learn about the cognitive aspects of eating, and why some people stop at a single slice while others devour the pie. This portable device has sparked the interest of researchers worldwide.

QR Pharma is a five-year-old start-up company based in Berwyn, but the young firm has been able to connect with well-known people and groups as it seeks funding to make drugs to treat Alzheimer's and Parkinson's diseases. In 2012, QR Pharma got $468,000 from the Michael J. Fox Foundation for Parkinson's Research to explore a compound called Posiphen as a potential treatment for Parkinson's. This grant is for work that will be led by Robert Nussbaum of the University of California, San Francisco, and Jack T. Rogers, an associate professor of psychiatry at the genetics and aging research unit of Massachusetts General Hospital.

* FRONTLINE. LEAGUE OF DENIAL: THE NFL'S CONCUSSION CRISIS. 9 tonight, WHYY12. HALL OF FAMER Harry Carson has a 3-year-old grandson who won't be playing football if Carson has anything to say about it. "I've told his mom, my daughter, that he's not going to play football. And his father has bought in," the retired New York Giants linebacker told reporters this summer during a news conference in Beverly Hills, Calif., for PBS' "Frontline" investigation "League of Denial: The NFL's Concussion Crisis.

Getting injured is a tricky thing. I'm a month into running again after being forced to take three months off. I thought recovery would be easier when I was allowed to hit the road again. Not quite. "It's very rare, in my experience, that physical rehab and emotional rehab progress at the same pace," said Joel Fish, sports psychologist and director of the Center for Sports Psychology in Philadelphia. And that's true. After a month off my feet - after the novelty of riding a stationary bike and having more free time wore off - I was ready to get back out there.
