Modern data science emerged in tech, from optimizing Google search rankings and LinkedIn recommendations to influencing the headlines Buzzfeed editors run. But it's poised to transform all sectors, from retail, telecommunications, and agriculture to health, trucking, and the penal system. Yet the terms "data science" and "data scientist" aren't always easily understood, and are used to describe a wide range of data-related work. What, exactly, is it that data scientists do? As the host of the DataCamp podcast DataFramed, I have had the pleasure of speaking with over 30 data scientists across a wide array of industries and academic disciplines. Among other things, I've asked them about what their jobs entail.

"When someone mentions scientists, chances are good that the face that pops into mind is male: perhaps a picture of Albert Einstein or Neil DeGrasse Tyson, or maybe a more generic man in a lab coat. However, even when women were largely shut out of science, there were still groundbreaking women making discoveries, conducting experiments, and publishing research! And while school curricula and popular culture are slowly expanding to include women beyond a few notable favorites such as Marie Curie and Jane Goodall, many people - young and old alike - still often find themselves struggling to name even a handful of female scientists. Fortunately, with the increasing availability of great biographies for children and teens, we can show our girls that women in science make contributions every day! And, of course, these titles are just as important to share with boys because all kids need to know that science is for girls! With that in mind, we've showcased 25 of our favorite biographies of female scientists for young readers. From primatology to physics, the expanses of space to the vast floor of the ocean, these women made their mark and changed the way we see the world... just like the budding Mighty Girl scientists of today will one day!

"Data scientists are in high demand, and command a median base salary of $110,000. Here are the skills you need to break into a career in the field, according to Glassdoor."

"etworking is a prime form of 21st century learning. The world is much smaller thanks to technology. Learning is transforming into a globally collaborative enterprise. Take for example scientists; professional networks allow the scientific community to share discoveries much faster. Just this month, a tech news article showcased how Harvard scientists are considering that "sharing discoveries is more efficient and honorable than patenting them." This idea embodies the true spirit of a successful professional learning network: collaboration for its own sake. "

"The guy who helped create the "Hour of Code," an event that even got President Barack Obama pecking out a line of JavaScript, almost sounded apologetic. "Not everyone should 'code,'" acknowledges Hadi Partovi, CEO and founder of Code.org, in a chat with EdSurge. But everyone should learn to think like a computer scientist, he adds. "We're about helping schools teach computer science," Partovi says, namely, to frame questions or information the way that computer scientists do."

"A great way to encourage girls' interest in STEM (science, technology, engineering, and math) fields is by sharing stories starring girls and women who love science and technology! Seeing female faces as scientists, whether in the lab or out in the field, is a powerful message to girls that these subjects are open to all. And, while introducing them to real-life women in STEM through biographies is important, fictional stories showing science-loving girls and women are another excellent way to entice girls with the unlimited possibilities before them. With that in mind, we're showcasing our favorite fictional books for both children and teens starring Mighty Girls who love science, engineering, and math. With options ranging from the fun and fanciful to the more contemplative, you're sure to discover a title to excite every budding scientist or engineer, girls and boys alike - after all, both need to learn that science is for everyone!"

"No mess.  No danger.  No smelly fumes. BBC Brit's Biggest Bangs is a fun, interactive video experience that allows users to channel their inner mad scientists, mixing dangerous chemicals with sometimes explosive results without a proper laboratory. The secret behind the interactivity is a central choose-your-own-adventure video around which annotations lead to separate videos that respond to your chemical selections. Choose your first chemical and then select another from among eight on the laboratory table.  You'll see the team scientist take each chemical from the table.  Then pause to consider-will it explode or won't it?"

"Brain scientists to work with schools on how to learn"

"We all know our chronological age. That's as simple as counting the candles on your birthday cake. But do you know your biological age? This second number measures not how many years you've seen, but how much those years have impacted the functioning of your body and brain. Scientists calculate it a number of ways, but whatever methodology they employ, they agree chronological and biological age don't always line up. Some 80-year-olds function like people decades younger. They ace their memory and cognitive tests, and scientists peering at their cells can even spot significant differences. Experts have dubbed these role models of healthy aging "superagers." Just about all of us would love to one day become one. How do you achieve that? A long and fascinating article in the latest issue of UCSF Magazine delves into the work of the University of California, San Francisco's Memory and Aging Center to answer this question (hat tip to PsyBlog). Much of this research is still far too new to be of everyday use, but science has already determined a few simple interventions you can start using today to help keep your brain young."

"Does the thought of doing long division, or solving a bit of algebra give you the shivers? You're likely to have maths anxiety. In our recent research, my colleagues and I found that in 80% of countries, girls have more negative feelings towards maths than boys. But this higher level of maths anxiety in girls is not justified by their actual level of performance and may put them off continuing a career in maths-related subjects, such as physics and computer science."

"Anyone who has spent time with 3- or 4-year-olds knows it can be exhausting. They're talkative, mobile, and independent, with a penchant for asking questions about everything. But well-structured pre-kindergarten classrooms are designed to harness that unbridled energy into enthusiasm learning. Colorful posters on the walls and stations set up for small group work ensure that kids are engaged in the new concepts and skills they learn."

"While Albert Einstein's genius isn't included, an exclusive iPad application launched Tuesday promises to make detailed images of his brain more accessible to scientists than ever before. Teachers, students and anyone who's curious also can get a look."
