So-called helicopter parents first made headlines on college campuses a few years ago, when they began trying to direct everything from their children's course schedules to which roommate they were assigned.

With millennial children now in their 20s, more helicopter parents are showing up in the workplace, sometimes even phoning human resources managers to advocate on their child's behalf.

Megan Huffnagle, a former human resources manager at a Denver theme park, recalls being shocked several years ago when she received a call from a young job applicant's mother.

A week after Christmas, many Americans are no doubt trying to figure out how to use the high-tech gadgets they got as gifts. This can be especially challenging for seniors. But a number of programs across the country are finding just the right experts to help usher older adults into the digital age.

For Pamela Norr, of Bend, Oregon, the light bulb went off as she, yet again, was trying to help her own elder parents with a tech problem. To whom did she turn?

"My teenage kids," she says.

The share of all U.S. adults who are married has dropped to a record low 51 percent, according to a new report. If the trend continues, the institution will soon lose its majority status in American life.

The report being released Wednesday by the Pew Research Center finds new marriages dropped a sharp 5 percent last year, which is very likely related to the bad economy. Pew senior writer D'Vera Cohn says it fits with a larger trend.

As many couples can attest — and lots of research backs this up — marital happiness plummets with the arrival of a baby. Sleepless nights, seemingly endless diaper changes and the avalanche of new chores that come with a newborn leave little time for the intimacies of marriage. It's a situation ripe for mental stress and marital discord.

A new survey finds a big disconnect when it comes to fertility. The age women think they can conceive a baby is far different from what their bodies are actually capable off. This poses an increasing problem, as more women wait longer than ever to have children.

Kate Donnellon Nail never imagined she'd have trouble conceiving. For one thing, people always tell the San Francisco musician she looks much younger than her 43 years.

"I work out regularly, I have a personal trainer," she says. "I've been doing yoga for 15 years."

From pregnancy on, parents often keep a stack of bedside reading full of advice on raising children — survival tips from the terrible toddler years through annoying adolescence. Los Angeles comedy writer Gail Parent figured she'd be done with all that once her kids turned the magical age of 21.

"Because I didn't tell my parents anything bad or negative," she says. "I let them be very peaceful about me when I was an adult. But I had told my kids to tell me everything when they were young."

Generation Xers — grown up now and in their 30s and 40s — are feeling hardest-hit by the recession, and are the most divided over the presidential candidates for 2012, according to a new report by the Pew Research Center.

Part of an ongoing series on obesity in America

From cubicle farms to auto factories, accommodating larger and heavier employees has become a fact of life. One in three U.S. adults is obese, and researchers say the impact on business can be boiled down to a number: $1,000 to $6,000 in added cost per year for each obese employee, the figure rising along with a worker's body mass index.

With the nation's student-loan debt climbing toward $1 trillion, it's taking many young people longer than ever to pay off their loans. Two-thirds of college students now graduate with debt, owing an average of $24,000. But some borrow far more and find this debt influencing major life decisions long after graduation.

"I was very naive, and I realize that now," says Stephanie Iachini, of Altoona, Pa. She was the first in her family to go to college and financed it herself. "Basically I was just signing papers because the education part meant a lot to me."

By some counts, fewer than half of Americans have ever tried to calculate how much they'll need for retirement. And those who do? In one recent survey, half told pollsters they just guessed.

A new poll for NPR, the Robert Wood Johnson Foundation and the Harvard School of Public Health finds retirement is proving more difficult than expected for many Americans, in large part because they haven't saved enough. So we set out to ask: How much do you need?

Americans pride themselves on being optimistic. But Robert Blendon, of the Harvard School of Public Health, says that may not be such a good thing when it comes to planning for retirement. For many Americans, it is proving harder than they imagined, according to a a new poll by NPR, the Robert Wood Johnson Foundation and the Harvard School of Public Health.

Sperm donation has long been shrouded in secrecy, and that seemed in the best interest of both the donors and the couples who used their sperm. But now a generation of donor-conceived children has come of age, and many believe they should have the right to know who their biological parents are.

First in a two-part report.

Women inseminated with a donor's sperm used to be advised to tell no one. Go home, doctors said, make love to your husband and pretend that worked. But in a trend that mirrors that of adoption — from secrecy to openness — more parents now do plan to tell such children how they were conceived and are seeking advice on how best to do that.

Tina Gulbrandson understands the temptation of secrecy. She felt stigma and pain when she needed to use another woman's eggs to get pregnant.

As more and more U.S. couples decide to have children without first getting married, a group of 18 family scholars is sounding an alarm about the impact this may have on those children.

In a new report out on Tuesday, they say research shows the children of cohabiting parents are at risk for a broad range of problems, from trouble in school to psychological stress, physical abuse and poverty.
