The biker gang shootout this weekend in Waco, Texas, that left nine people dead, 18 wounded, and as many as 192 facing organized crime charges has sparked a lot of scrutiny over how police and media are treating this incident compared with how they approached the protests in Ferguson, Mo., and Baltimore.

At schools that offer comprehensive sex education, students tend to get the biology and the basics — they'll learn about sexually transmitted diseases and pregnancy, how to put a condom on a banana and the like.

But some public health researchers and educators are saying that's not enough. They're making the case that sex ed should include discussion about relationships, gender and power dynamics.

They switched diets.

Twenty South Africans gave up their corn porridge and vegetable stews for burgers and fries.

And 20 Pittsburghians sacrificed fast food staples for the low-fat, high-fiber fare that South Africans traditionally eat.

Dr. Stephen O'Keefe, a professor of nutrition at the University of Pittsburgh School of Medicine, was eager to find out what would happen next.

O'Keefe knew that South Africans tend to have much lower rates of colon cancer than Americans. And he wanted to find out if food might be a factor.

When Jeff Brown opened his first grocery store in a low-income neighborhood in Philadelphia back in 2004, it seemed like a long shot.

Most people thought he was crazy to even attempt to make money in a food desert like Southwest Philly, he says. Other grocers had tried and quickly gone out of business.

Missing out on sleep pretty much guarantees feeling crummy the next day. But it can also lead to dangerous or even disastrous decision-making. Sleep-deprived operators failed to prevent the Chernobyl nuclear power plant meltdown and the Exxon Valdez oil spill.

And during the Civil War, some historians think that Confederate Gen. Stonewall Jackson's confused command during the battles of June 1862 was due to sleep deprivation.

It's just Wednesday, but maybe you're already crashing. You've got three deadlines to juggle, your boss is breathing down your neck and Lillith from Finance is being a total pain.

Here's a bit of research that might reassure you it's all worth it.

Challenging work that involves lots of analytical thinking, planning and other managerial skills might help your brain stay sharp as you age, a study published Wednesday in the journal Neurology suggests.

Will a kids' meal sans fries and soda still tempt the youngest diners at restaurants?

Chef Ype Von Hengst certainly thinks so. He's the co-founder of Silver Diner — a chain of fast-casual restaurants in Virginia and Maryland.

Customers want healthier options for their kids, Hengst says. "We tempt them with the stuff they like, but we make sure it's also good for them," he says.

A version of this story was first published on April 5, 2014. It has been updated.

The majority of Americans now live in cities and have very little to do with the production of their food.

We've all heard that an aspirin a day can keep heart disease at bay. But lots of Americans seem to be taking it as a preventive measure, when many probably shouldn't.

In a recent national survey, more than half the adults who were middle age or older reported taking an aspirin regularly to prevent a heart attack or stroke. The Food and Drug Administration only recommends the drug for people wh have already experienced such an event or are at extremely high risk.

Danny Kou, the executive chef at La Mar, an upscale Peruvian restaurant in San Francisco, says it's a good time to be him.

Kou moved from Lima to the United States when he was 21. It was 2001, and back then, Peruvian cuisine was still unfamiliar in North America.

Think back to the last time you got negative feedback — like when your doctor suggested you lay off the cigarettes or when your mother advised you to get rid of that ridiculous goatee.

Though we all understand the value of constructive criticism, we don't like hearing that we've done something wrong. And the knee-jerk reaction is to act defensive.

But if you focus on the big picture and future goals, you may be able to trick your mind into being a bit more receptive.

The transition to adulthood marks a big turning point in life for everyone, but for young people on the autism spectrum that transition can be really tough.

Young adults with autism had lower employment rates and higher rates of complete social isolation than people with other disabilities, according to a report published Tuesday by the A.J. Drexel Autism Institute.

"If aliens beamed onto Earth and read our school textbooks, they wouldn't have a clue about what women contribute to our society," says Rae Blumberg, a sociologist at the University of Virginia.

Blumberg has spent years looking at textbooks from all over the world. In almost every country she has studied, women are either completely written out of texts — or they're portrayed in stereotypical, often subservient roles.

We donate to charities for lots of reasons: because we're generally magnanimous people, because we care deeply about certain issues or because it's the only way to get Meg to stop talking about the plight of the endangered proboscis monkey.

And for men, there may be another force at play: a subconscious desire to impress the ladies.

Dana Lam was insured under her parent's health plan until the end of 2014, thanks to a provision of the Affordable Care Act that allows young adults to stay on family health insurance until they turn 26.

The arrangement worked out well until she needed treatment for depression. Lam knew that if she used her parents' health plan to see a psychotherapist or psychiatrist, her visit would show up on their insurance statements.

She wasn't ready to talk to them about her mental health issues. "I was just so afraid of having that conversation with them," she says.

Christina Costanzo was 32 when she had her first heart attack. It all started on a Friday.

"I had chest pain. I had pain in my jaw, pain going down my left arm. I had some shortness of breath," Costanzo recalls.

But Costanzo who is a nurse practitioner in New Haven, Conn., didn't realize right away that these were symptoms of a heart attack. She figured this was just her body reacting to stress, and she didn't want to overreact.

About 10 years ago, Dr. Swaminatha Mahadevan was conducting research at a Nepalese hospital, when he witnessed something that would never have happened back home in California.

The majority of teenagers with mental health issues don't get help. But maybe if help were just a text message away — they wouldn't be so hesitant to reach out.

That's the thinking behind NYC Teen Text, a pilot program at 10 New York public high schools that allows teens to get help with mental health issues by text.

My father usually starts off his curries by roasting a blend of cinnamon, cardamom, coriander, anise, cumin and bay leaves. Then he incorporates the onions, garlic and ginger — and then tomatoes and chilies and a touch of cream.

The North Indian cuisine I grew up eating is about melding together distinct, disparate flavors and building up layer upon layer of spice and seasoning. Much of European cuisine, by contrast, is about combining complementary flavors — think potatoes with leeks, or scallops with white wine.

While most teenagers recognize that texting while driving is a bad idea, they may be less clear about the risk of other activities – like changing clothes.

Twenty-seven percent of teens say they sometimes change clothes and shoes while driving, a study finds. They also reported that they often change contact lenses, put on makeup and do homework behind the wheel.

The boy was abducted by the Lord's Liberation Army to serve as a child soldier when he was 7. He had been forced to kill his uncle with a machete.

At 14, he escaped and made his way back to his parents. But he wasn't himself.

He couldn't sleep at night, and during the day, he'd run around the village screaming. He was fighting back thoughts of suicide.

"No one knew what to do with him," says Peter Oketayot, a mental health counselor with the nonprofit Vivo in Northern Uganda, who eventually treated the teenager.

Suicide is the third leading cause of death for adolescents and young adults, and those who live in rural areas are especially at risk.

For young people between the ages of 10 and 24, the suicide rates in rural areas are nearly double those of urban areas, according to a study published Monday in JAMA Pediatrics. And that disparity is growing.

Most colleges require students to go through some sort of alcohol education program. When I was a freshman in college, I was required to play a video game that involved helping Franklin the frog navigate through various college parties without succumbing to alcohol poisoning. (Easy, Frank, remember to hydrate).

Other universities require students to watch educational videos or take online quizzes about appropriate alcohol use.

Each year more than 15,000 women under the age of 55 die of heart disease in the United States. And younger women are twice as likely to die after being hospitalized for a heart attack as men in the same age group.

It doesn't help that women tend to delay seeking emergency care for symptoms of a heart attack such as pain and dizziness, says Judith Lichtman, an associate professor of epidemiology at the Yale School of Public Health. "We've known that for a while," she says.

Type "drunk," "hammered," or "trashed" into YouTube's search bar and some pretty unsavory videos are likely to turn up.

And that can't be good for teenagers and young adults, researchers say. User-generated YouTube videos portraying dangerous drinking get hundreds of millions of views online, according a study published Friday in the journal Alcoholism: Clinical and Experimental Research.

Your tongue doubtless knows the difference between a high-fat food and the low-fat alternative. Full-fat ice cream and cream cheese feel silkier and more sumptuous. Burgers made with fatty meat are typically juicer than burgers made with lean meat.

OK, so, we've long known fat gives food a desirable texture. But some scientists are now making the case that we should also think of fat as the sixth primary taste, along with sweet, salt, sour, bitter and umami.

Trying to find a date on Tinder feels a bit like playing a video game. You quickly browse through photos on your phone. If he's cute swipe right, and the app will let you know if he likes you back. If he's posing with a fancy car or a baby tiger, make a gagging sound and swipe left.

Log into OkCupid, and the suitors are purportedly better curated. The app has you answer hundreds of hard-hitting questions like, "How often do you brush your teeth?" and, "Do you like scary movies?" The app then matches you with potential dates who supposedly share interests and values.

College is in many ways a time to learn life skills. But students often get so bogged down building up their resumes and studying for that Rocket Science 101 midterm that they've got no time left for the basics — like cooking.

People in Cambodia experience what we Americans call depression. But there's no direct translation for the word "depression" in the Cambodian Khmer language. Instead, people may say thelea tdeuk ceut, which literally means "the water in my heart has fallen."

Anxious or depressed Haitians, on the other hand, may use the phrase reflechi twop, which means "thinking too much." And in parts of Nepal and India, people use the English word "tension."

Emily Hu is a veritable master chef of the dorm room.

No oven? No problem. The college student is skilled at navigating the cooking limitations of campus living — she can whip up cakes with just four ingredients and a microwave, and make muffins in a toaster oven.
