The first kids of US presidents are in the public eye almost as much as their parents. They dictate fashion trends, appear on their parents' behalf at embassies around the world, and sometimes host senior prom in the White House East Room.

You know, normal kid stuff.

But when the first family departs 1600 Pennsylvania Ave., the spotlight typically turns away from them.

To celebrate the Fourth of July — which also happens to be Malia Obama's birthday — we decided to find out what the first children are up to these days.

Chelsea Clinton serves as vice chair of the Clinton Foundation.

Daughter of Bill and Hillary Clinton

The apple doesn't fall far from the tree when it comes to Chelsea Clinton. As her mother focuses her attention on a presidential campaign, Clinton has zeroed in on the Clinton Foundation, championing the group's advocacy work in global health and childhood obesity. Previously, the Stanford grad worked as a special correspondent for NBC News.

Clinton, 35, and husband Marc Mezvinsky welcomed a little girl named Charlotte into their family last summer.

Steven Ford appeared on seven seasons of "The Young and the Restless."

Son of Gerald and Betty Ford

Wild-child Steven Ford, 59, joined the cast of television soap opera "The Young and The Restless" in 1981, playing P.I. Andy Richards. After six seasons and a role reprisal in 2002, he has since appeared in a number of films, including "Armageddon,""Black Hawk Down,""When Harry Met Sally," and "Transformers."

Ford recently ended his tenure as chairman of the Gerald R. Ford Presidential Foundation (though he remains on the board of trustees), but continues to honor the legacy of his father's administration, speaking at town-hall events and lectures around the country.

Caroline Kennedy serves as the US ambassador to Japan.

Daughter of John and Jackie Kennedy

After a lifetime of training in diplomacy, Caroline Kennedy landed the perfect job for her — as the US ambassador to Japan. But she stirred a Twitter controversy when she publicly condemned the annual dolphin hunt, a Japanese tradition.

The former attorney, 57, also serves as president of the JFK Presidential Library and has written nine best-selling books on constitutional law, American history, and poetry. Like her father, she's a strong advocate for free trade, and encourages Democrats to take the same approach for the good of US-Asia relations.

When we think of a true American, a few qualities come to mind: strong, resilient, talented, innovative, and pioneering. 

In honor of the Fourth of July, we've created a ranking of Americans who possess all these qualities. They've all helped to shape the social, economic, cultural, and political landscape of our country within last year (and many, much longer than that).

From recording artists to politicians to athletes to activists, scroll through to find out who we think is truly patriotic this year.

John Green is the voice of a generation: All three of his young adult novels — including heartbreaking teen love story "The Fault in Our Stars"— have been bestsellers and two of them have been made into feature films. He and his brother also host a huge video bloggers conference annually.

Say what you will about Facebook, but Mark Zuckerberg popularized social media and has connected millions of people around the country — and now more than a billion around the world — through the social network.

Elizabeth Holmes is a one-woman powerhouse. Her $9 billion biotech company Theranos is turning the medical industry upside down. She's the youngest female self-made billionaire and a stellar innovator — what's more American than that?

Greece has rich ancient history and Mediterranean beauty, but lately it's been in the news because because of its economic upheaval. 

While more than 60% of Greek voters rejected a proposed bailout deal during Sunday's referendum, the country was long divided between those who were hoping for a "yes" vote and those who were hoping for a "no."

Still, there's a lot the majority of Greeks have in common, from their patriotism to their willingness to spend $5 on a cup of coffee. Here are 12 things you may not have known about the majority of Greeks.

Abe Davis is finding new ways to use video by using the vibrations in it to reconstruct audio.

No sound? No problem. Abe Davis and a team of researchers from MIT, Microsoft, and Adobe developed an algorithm that can extract audio from silent videos by analyzing the tiny vibrations of the objects as captured by a camera.

In one experiment, the team filmed earbuds playing a song with no discernible sound. The vibrations of the earbuds in the video was enough to recreate a song identifiable by the app Shazam. When the team tried the experiment using an everyday point-and-shoot camera, as opposed to an expensive high-speed version, the vibrations were still able to reconstruct the sound. Davis presented these findings in a paper for Siggraph, a computer-graphics conference, and gave a TED talk where he demoed the visual microphone. And there’s more to come: The latest research from Davis and fellow graduate student Katie Bouman will be out this summer.

Davis is a doctoral student at MIT.

Alan Stern is spearheading the most important space mission of 2015.

On July 14, 2015, the NASA spacecraft New Horizons flew by Pluto — closer than any other human-made instrument has ever been. Alan Stern is spearheading the mission, leading the team of scientists that made sure the spacecraft survived its nine-year journey through space. 

Until New Horizons reached its closest approach to Pluto, little was known about this dwarf planet and its system of five moons. Now the NASA spacecraft has collected data that Stern and his team will be analyzing over the coming months to understand the geology, composition, and atmospheric content of Pluto in significant detail, something that would never have happened without the New Horizons spacecraft.

Stern is the principal investigator for NASA's New Horizons mission.

Andrea Accomazzo was the first person to land a probe on a comet.

In August 2014, the Rosetta spacecraft began orbiting the comet 67P Churyumov-Gerasimenko and transmitting images to Earth of the dusty space snowball that were more detailed than anything we'd ever seen.

Ultimately, Rosetta will give scientists a better idea of what comets are made of and how they work, as well as provide insights into the chemical makeup of the solar system. As the Rosetta flight director, Andrea Accomazzo helped design the mission and led the team that guided it toward 67P. Now he's working with the European Space Agency on their interplanetary missions to Mercury, Mars, and Jupiter.

Accomazzo is an ESA spacecraft-operations manager at Venus Express and the flight director of the Rosetta mission.

Square is one of the easiest mobile payment systems for businesses to use.

Square is a software platform that enables retail stores and restaurants to accept mobile payments via iPads, iPhones, or Android devices. 

Jack Dorsey, the company's founder and CEO, is also currently serving as Twitter's interim CEO; just after news broke that Dorsey would step in at Twitter, reports surfaced that Square was planning to go public. Sources say the company may have already filed a confidential registration document with the SEC, which is permitted for companies with less than $1 billion in revenue.

Square's most recent round came in late last year, when it raised $150 million at a reported $6 billion valuation.

Lending Club allows peer-to-peer financing.

Lending Club is one of the world's biggest online lending marketplaces. Last year, Lending Club's IPO was the largest among all US tech companies. Renaud Laplanche, the company's CEO, founded Lending Club to let people provide low-cost financing to their peers. Now, it lets institutional investors do the same.

The online credit marketplace raised $870 million in its IPO last December. It's valued at more than $7 billion.

Stripe helps developers and website owners accept any type of payment method.

In September, Apple announced partnerships with a number of retailers and payments companies for its Apple Pay service. Among them was Stripe, a five-year-old mobile-payments startup. According to its website, Stripe currently powers businesses out of nine global offices in 20 countries. The company focuses on beautiful code and design to create user- and developer-friendly experiences.

Recently, Stripe has been in talks to raise a funding round that could see the payments company, which has previously raised $190 million in funding, reach a valuation of $5 billion.

Bertolt Meyer dispels stereotypes and stigmas surrounding physical disabilities.

Bertolt Meyer is best known for hosting "The Incredible Bionic Man," a documentary about the state of modern bionics, a field in which engineers apply the designs seen in biology to create more responsive prosthetics, artificial organs, and more. A social psychologist, he uses his own condition to relate to others and hopes advances in bionics will help dispel stereotypes and stigmas around physical disabilities.

Meyer wears a bionic hand called an i-limb ultra revolution on his left arm. Though he used a series of different prosthetics growing up (he was born without the lower part of his left arm), he transitioned to the i-limb in 2009 because it was far easier to use, move, and interact with the environment around him.

Meyer is a professor at the University of Leipz

Hugh Herr develops smart limbs for amputees, including himself.

Hugh Herr develops bionic limbs for amputees, and with two bionic legs himself, it's an industry he's personally invested in. At MIT’s Media Lab, he creates new and better legs for amputees. The lab's biohybrid smart prostheses and exoskeletons integrate microcomputers that monitor things like joint pressure and gait, allowing the limbs to respond to the body the same way biological legs would. The prosthetics are available through BiOM Inc., which Herr founded.

Herr is an associate professor and leads the biometrics research group at MIT’s Media Lab.

Climate and environmental scientists are vital to the future of our civilization. After all, they dedicate themselves to studying the planet we call home to solve climate problems despite the criticism they face.

Eric Rignot is drawing public attention to the irreversible impacts of climate change.

Glaciologist Eric Rignot used satellite-radar observations to conclude that the West Antarctic glacier is quickly melting, and that there's no way to reverse it. For his remarkable 2014 study, Rignot and a team of researchers looked at the five Amundsen Sea glaciers in West Antarctica, mapping the bedrock under the ice. Because there's no ridge holding the ice in place, nothing exists to help slow the ice sheet's inevitable collapse. "Ice is going to retreat from this sector for decades and centuries to come, and we can't stop it,"Rignot told Nature.

Rignot recently coauthored an alarming study, led by NASA's former lead climate scientist James Hansen, that concludes that glaciers in Greenland and Antarctica will melt 10 times faster than previous consensus estimates, resulting in a sea-level rise of at least 10 feet in as little as 50 years. 

Rignot is a professor at the University of California at Irvine.

Gavin A. Schmidt is pinpointing the roots of climate change.

Climate is affected by tons of different variables, including tiny, uncontrollable shifts in our oceans to the massive amounts of greenhouse gases humans are adding to the atmosphere. As the director of NASA's Goddard Institute for Space Studies (GISS), Gavin A. Schmidt develops detailed climate models that illustrate the effects of each of these factors. In 2009, he and photographer Joshua Wolfe coauthored "Climate Change: Picturing the Science" to show how climate change is changing the face of the planet.

Schmidt is the director of NASA’s Goddard Institute of Space Studies and principal investigator for the GISS ModelE Earth System Model.

Ian Joughin made a stunning discovery about the future of the West Antarctic Ice Sheet.

The Thwaites Glacier will inevitably collapse in less than a few hundred years, raising sea levels by about 2 feet total all on its own. The Thwaites holds the entire West Antarctic Ice Sheet together, and its loss means the inevitable loss of the entire sheet, the researchers said.

That will cause sea levels to rise up to 13 feet when it melts completely. Glaciologist Ian Joughin and his team were able to model the glacier’s deterioration over the last 18 years, and used that data to predict how the melting will look in coming decades.

Joughin is an affiliate professor of Earth and space sciences at the University of Washington.

True power is ageless.

From the toddling Prince George, third in line to the British throne, to 100-year-old Pulitzer Prize-winning author Herman Wouk, we found the most powerful person at every age from 1 to 100.

To create this list, we took four criteria into consideration: command, or the degree to which a person formally controls a group of people; past influence, or how much a person has changed the world; future influence, or how much a person is likely to change the world going forward; and net worth.

Spanning industries and time zones, these are the most powerful people, from 1 to 100.

AGE 1: Prince George of Cambridge

Heir to the British throne

What makes him powerful: After his grandfather and father, little George is next in line to succeed his great-grandmother, Queen Elizabeth II. As an eight-month-old he took his first royal tour — a 19-day visit to New Zealand and Australia. He's also a tiny fashion icon, and he recently became a big brother to new princess Charlotte Elizabeth Diana.

AGE 2: Macallister Bogue

Son of Marissa Mayer and Zach Bogue

What makes him powerful: While he's only a couple of years old, Bogue, son of Yahoo CEO Marissa Mayer, still influences his mom's outlook at work. Though Mayer herself only took a few weeks off after giving birth, she doubled the amount of paid maternity leave Yahoo offers new mothers from eight to 16 weeks and offered new dads eight weeks as well.

AGE 3: Blue Ivy Carter

Daughter of Beyoncé and Jay Z

What makes her powerful: Nothing is too good for this power couple's little girl. Blue Ivy's second birthday was celebrated at the exotic Jungle Island in Miami; for her third, Blue got an ice sculpture with her name carved into it. Gwyneth Paltrow, who is good friends with the Knowles-Carter clan, said of Blue Ivy: "She is a powerhouse. I love her so much."

Princeton University is one of the smartest and most historic colleges in the country.

AddLive

Founder: Kavan Seggie

Last May, Snapchat made its first acquisition in AddLive, a real-time communications startup that allows the picture-messaging app to power its video-calling feature. The deal cost Snapchat $30 million.

AddLive's technology offers several useful tools to Snapchat, including screen-sharing, multiparty conferencing, and support for browser-based video chat via WebRTC.

Facebook

Cofounder and CEO: Mark Zuckerberg

Facebook has been quietly busy this year with new features. For example, it acquired a video startup called QuickFire, which could help streamline the increased video consumption on Facebook.

At Facebook’s annual F8 developers' conference, David Marcus, head of messaging products, made a big announcement regarding Facebook Messenger: expansion into e-commerce and mobile payments inside the app. Marcus has helped the company roll out several other features as well, including a Skype-like video-calling service and the ability to send locations to friends.

The League

Founder and CEO:Amanda Bradford

The League is like a curated Tinder for elites, and it raised $2.1 million in seed funding earlier this year to play matchmaker to the most successful and ambitious singles. The League launched in San Francisco at the beginning of 2015 and just opened up to the New York market as well, where a targeted group of 2,500 users were allowed to sign up.

The goal, founder Bradford says, is to make more power couples and help people date "intelligently." The app now has its sights set on London.
