This Treehouse Is More Than Just an Outdoor Clubhouse

Metal sculptures, installations made of reclaimed materials and sprawling animal art murals adorn the grounds at the Lincoln Street Art Park in Detroit.
The park, located in a vacant lot behind local nonprofit recycling center Recycle Here! was not only meant to turn clutter into a community resource, but to create a space for local artists and children to appreciate the concept of green art.

“The act of recycling is for the generation behind you,” said Recycle Here! founder Matthew Naimi. “For kids, recycling is an answer for cleaning up their city. They see the litter and dumping all around them, and they don’t like it.”

And now, the recycling center is teaming up with educational nonprofit Green Living Science (GLS) to attract even more city kids to the local art park by turning a shipping container into a giant treehouse and learning lab. “Activi-Tree,” a large treehouse with the shipping container at the base, would be a year-round classroom for field trips and programs at the Lincoln Street Art Park, according to MLive.com.

The groups are aiming to raise $8,000 for the project, commissioning artists, welders, and designers to help create the outdoor classroom that will teach STEM-focused courses and environmental science while promoting the “three R’s” of recycling: reduce, reuse and recycle. The giant treehouse will use solar-powered LED lights, which will also light up the park, according to GLS.

Both organizations have extensively worked with city schools to teach children recycling through school assemblies, professional development programs, and in-class presentations. This year alone, the two organizations have implemented programs in 25 schools. With the addition of a treehouse learning lab, Lincoln Street Art Park could be the perfect backdrop to inspire the next generation of urban planners.

Is Crowdfunding the New Way to Pay for Important Scientific Studies?

Even if you don’t know much about fracking (the process through which oil and gas companies pump water, sand, and chemicals into the ground to release oil or natural gas), you probably know that, politically-speaking, it’s a controversial topic.
Many people who live close to fracking operations fear that the process or its byproducts could harm them or the environment. But because of its polarizing nature, it’s difficult to land funding for non-biased scientific research on fracking.
Studies funded by industry groups have (of course) found no potential harm to humans from the practice. Citizens of several Colorado towns are skeptical, however, and have passed bans on fracking within their communities’ borders that may or may not hold up in court.
Nelson Harvey writes for High Country News that “the government’s own research on fracking is coming under fire from both sides of the political spectrum,” with the EPA recently responding to criticism by backing away from results of a 2011 study that found fracking to be the cause of the pollution of an aquifer in Wyoming. The state of Wyoming will continue the study, but it will now be funded by EnCana, the oil company responsible for fracking in the area.
Outside of industry-sponsored research, there’s little funding available to study fracking as federal grants for such studies have been slashed. So this year, at least four scientists have turned to crowdfunding to finance their research.
Dr. Susan Nagel of the University of Missouri is currently seeking to raise $25,000 through Experiment.com for her study: “Does fracking contaminate water with hormone disrupting chemicals?” She’s already gained $19,000 in backing, so apparently many people have the same question.
Harvey notes that, so far this year, University of Washington researchers successfully raised $12,000 through Experiment.com to study fracking’s effects on air pollution in Utah and scientists from Juniata College collected $10,000 through crowdfunding to research fracking’s impacts on streams in Pennsylvania. However, one fracking study proposed by a University of Colorado biologist failed to garner the necessary backers.
When a combination of budget cuts and political pressure makes it hard to study a certain topic, perhaps seeking donations from the questioning public is the best way to find answers to some of science’s most pressing questions.

This Program Shares Its Wisdom About Producing Minority Ph.D. Science Students

It goes without saying that the folks at the University of Maryland, Baltimore County (UMBC) know a thing or two about supporting and encouraging minority and low-income undergraduate students in continuing their studies and earning science Ph.D.s.
Impressively, over the past two decades, the Meyerhoff Scholars Program at UMBC has produced 900 graduates who have gone on to rack up 423 advanced science degrees and 107 medical degrees.
Compare that to Penn State, which was recently named one of the top 40 schools for educating black students who eventually earned advanced science degrees. Despite the recognition, the public university earned that status by producing just four (!) degrees earned by black science students out of about 3,000 STEM students total.
“The data is shocking,” Penn State Chemistry professor Mary Beth Williams told Jeffrey Mervis of Science Insider. “Clearly we have to do a better job.”
So the people behind UMBC’s successful Meyerhoff Scholars Program will mentor faculty and staff at Penn State and the University of North Carolina in an attempt to increase the number of minority students enrolled in science Ph.D. programs. Over five years, the Howard Hughes Medical Institute will dedicate $7.75 million to the effort.
Clearly, UMBC has figured out a formula that keeps minority and low-income students on track to become scientists: Close monitoring of academic progress, a summer program for incoming freshmen, scholarships, research opportunities, and a close cohort of talented students who foster a sense of teamwork with each other. Its current four-year class of Meyerhoff Scholars includes 300 students, 60 percent of which are underrepresented minorities.
Williams said she plans to study these lessons carefully in the program’s implementation at Penn State. “My goal is to clone it as much as possible. It’s been successful for 25 years, so why mess with it? The more you change, the more you’re inviting failure.”
The president of UMBC, Freeman Hrabowski, is proud of how the scholars program has grown from its initial class of 19 African-American male science students in 1989. “What Meyerhoff has done is get us to think about our responsibility to students who say they want a STEM degree,” he told Mervis. “And what helps underrepresented minorities will also help the rest of our students.”

America’s Future: Meet the 2014 White House Science Fair Exhibitors

On Tuesday, the White House was the backdrop to the country’s brightest students and their innovations — including hovercrafts, robots, and solar energy-powered contraptions — that potentially could be the game-changing ideas that make up America’s future.
At the fourth annual White House Science Fair, President Barack Obama welcomed a host of youth from across the country to share their ideas, designs, and experiments in science, technology, engineering and math (more commonly known as STEM subjects). This year’s event also focused on females excelling in STEM fields, according to the White House website.

“If you win the NCAA championship, you come to the White House. Well, if you’re a young person and you produce the best experiment or design, the best hardware or software,” said President Obama, “you ought to be recognized for that achievement, too.”

Among the host of young people was 12-year-old Peyton Robertson. As a native of Fort Lauderdale, Florida, Robertson is familiar with flooding and salt-water damage since he grew up in the area of the Sunshine State where hurricanes often strike. So he created a “sandless” sandbag that efficiently protects flood zones. He was recognized as America’s Top Young Scientist at the 2013 Discovery Education 3M Young Scientist Challenge and received $25,ooo for his lightweight, effective design.

Elana Simon, 18, also presented her work, which focuses on patients coping with fibrolamellar, a type of rare liver cancer that she herself endured at age 12. Simon worked with one of her former surgeons to gather tissue samples from fibrolamellar patients to perform genomic sequencing tests and discovered a common genetic mutation among them. Her results have been published in the renowned journal Science, plus she is a recent winner of the American Association for Cancer Research’s Junior Champion in Cancer Research Award. She has also presented her work in front of 16,000 cancer researchers and will attend Harvard this fall to study computer science.

Girl Scout Troop 2612 of Tulsa, Oklahoma, were also among their much-older peers, presenting their design for a “Flood Proof Bridge,” which includes a computer program that automatically retracts the bridge when flood conditions are detected by a motion sensor embedded in the river bed.  Eight-year-olds Avery Dodson, Natalie Hurley, Miriam Schaffer, Claire Winton, and Lucy Claire Sharp came up with the model as part of the Junior FIRST Lego League’s Disaster Blaster Challenge, which prompted elementary school students to experiment with simple machines, motorized parts, engineering, and math to create solutions for natural disasters like floods and earthquakes. The intrepid troop built the idea on the notion that first responders had trouble reaching certain communities because of bridges in the wake of the Estes Park, Colorado flood. They not only built the model but also developed the computer program, too.

Can Wetland Restoration Be Good for Business?

If you can’t beat ’em, sell to ’em.
For years now, big businesses and big utilities have been viewed as Public Enemy #1 of the environment — hurting much more than helping. But one Louisiana firm, Tierra Resources, has found a way to turn energy companies’ needs into a possible win for Mother Earth: By making the preservation of precious coastal wetlands financially worthwhile, according to Next City.
The key? Carbon offsets.
Wetlands protect coastal development, provide homes for wildlife, and drink up the carbons in the atmosphere linked to global warming. In many areas, unfortunately, wetlands have disappeared, being drained for development or eroded by storms. While many argue that wetland restoration is necessary, the work could cost billions.
But there’s where the idea of carbon offsets (where a firm purchases the rights to create more carbon from another firm that can mitigate carbon) enter the equation.
If, say, Entergy, a Louisiana utility firm, can restore more wetlands on company-owned real estate, that ground could offset some of Entergy’s carbon emissions. And it could reduce the $50 billion-plus projected price tag for rebuilding an ecosystem so vital to the state and to the world.
Tierra Resources helps make this possible by developing a detailed system of scientifically tracking and verifying the carbon offsets the wetlands provide. While the science is fairly convoluted, it’s promising enough that Entergy has sunk $150,000 into a pilot program, Tierra reports.
The Ecosystem Marketplace reports that energy giant ConocoPhillips is also considering investing in wetlands reclamation. That might be a drop in the multinational firm’s budget, but it’s potentially a big deal for the environment, as the company owns 640,000 acres of wetlands — making it one of the biggest single owners of such land in the United States.
Perhaps this will ultimately be the key to turning the tide of wetlands, and the environment. If doing the earth-friendly thing isn’t inspiration enough, making responsible environmental stewardship a savvy business decision has to spur change, right?
 

Could 3-D Printing Help Find A Cure For Cancer?

Imagine if you had a cancerous tumor, and your doctor could determine the best course of treatment by printing a three-dimensional (3-D) replica of the mass. You’d probably sign up immediately, right?
Thanks to researchers at Drexel University in Philadelphia this could soon be a possibility.
Dr. Wei Sun and his staff have discovered new research on expediting the process of testing cancer drugs through the use of 3-D printers. The technology means doctors can print a living tumor (or a mixture of cancerous and healthy biomaterial) at such high resolution that the cells can be examined with extreme precision, according to Fast Company.
Typically, the drawn-out process requires testing drugs on cancer cells in a Petri dish, then on 3-D tumors in animals and — with a comprehensive record of trials — eventually on humans. But this process is far from ideal. Why? First off, what works in two-dimensional form may not work in 3-D. Not to mention that what works on animals may not always work on humans. Formulas can fail when switching test subjects, which is why developing cancer drugs can be such a costly venture, according to Sun.

“Doctors want to be able to print tissue, to make organ on the cheap,” Dr. Sun said. “This kind of technology is what will make that happen. In 10 years, every lab and hospital will have a 3-D printing machine that can print living cells.”
By using 3-D printing technology, doctors can speed up the process of drug development but also potentially use it to personalize cancer treatment. The accuracy to print out multi-shaped tumors of different sizes means that a doctor can determine what drugs would work the best by simulating it with the printed version.
With cancer being such a costly and widespread disease, Sun’s venture has the potential to revolutionize treatment and save countless lives.

Scientist Chic: Fashion Accessories Every Mom Will Want for Her Daughter

When you close your eyes and picture a scientist, what comes to mind? Olivia Pavco-Giaccia, a 19-year-old sophomore at Yale University, knows your answer. It’s probably an “older man, maybe some crazy hair, a white lab coat, some plastic goggles,” she says. Right?

Ever since she was a child, Pavco-Giaccia has understood well the stereotype of the scientist. In grade school, she loved the science lab, the precise measurements, the elegant connections between the parts of the body or of a plant, the cause and effect of experiments. But when she thought about the traditionally male, geeky, socially maladroit scientist paradigm — and, after all, most scientists think in terms of paradigms — she felt a little put off. “There’s not a whole lot in that image that a young girl can relate to,” laments Pavco-Giaccia, a major in cognitive science.
Enter a hot glue gun and some rhinestones, and before you could say “Golgi apparatus” Pavco-Giaccia had transformed the geeky profile: She took the frumpiest part of the scientist’s uniform — the plastic lab goggles — and decked them out with rhinestones,  creating something truly eye-catching. The summer after her junior year in high school, while working in a neurobiology lab at Stanford University, she wrote a post about lab safety on her blog, LabCandy: A Girl’s Guide to Some Seriously Sweet Science, and accompanied it with a photo of herself wearing her sparkly bedazzled spectacles. Hundreds of girls from around the country — young women Pavco-Giaccia didn’t realize even followed her blog — responded excitedly. A movement was born.
MORE: What Has Two Pom-Poms a Ph.D and a Passion for Science?
The goal of LabCandy is to cultivate girls’ interest in science and to show them that the field has room for girls like them. By any measure, there’s a whole lot of room: Currently, women hold only 24 percent of STEM jobs (shorthand for science technology, engineering and math). Even at Yale, tenured male professors in the physical sciences departments outnumber their female counterparts by nearly 8-to-1. The reasons for the underrepresentation are many: a widely acknowledged institutional bias against female scientists, a lack of mentorship and encouragement of young women scientists, and a general unwelcoming atmosphere in the lab toward females. A pair of pretty goggles may not resolve such social prejudices, but they might inspire young women to consider a field that once seemed closed to them. “Of course you don’t need bedazzled lab goggles to be a scientist, but they made the experience fun for me and they might just help draw another girl in and let her see science as an option, too,” says Pavco-Giaccia.
To take LabCandy from hypothesis to thesis — that is, to get the idea to market — LabCandy needed an angel. Pavco-Giaccia found hers in the Yale Entrepreneurial Institute (YEI), a startup accelerator on campus. The grueling YEI application process required her to ponder over the details of what a bona fide LabCandy company would look like. How would she take her rhinestone goggles beyond mere accessory and make them a catalyst for girls to pursue science? Pavco-Giaccia had to create a business model, along with an analysis of her target audience and potential demand for her products (which also include books and funky lab coats). “There really isn’t anything out there right now like LabCandy,” says Pavco-Giaccia, acknowledging that many other companies and nonprofits are already paving the way in breaking down gender barriers in STEM. “The company that’s been in the news most recently is GoldieBlox” — whose made-for-girls engineering toys have won widespread praise. “It has really taken off, in large part, I believe, because [its] mission of getting girls more interested in STEM resonates with parents, teachers and business and government leaders. We hope that that resonance will help LabCandy and its mission succeed, too,” she says.
In the spring of her freshman year at Yale, Pavco-Giaccia won a fellowship at YEI — and the support she needed to hone her idea. Quickly, she realized that LabCandy needed an artist type to complement her scientist — and she knew the perfect person to recruit, May Li, her best friend since kindergarten and a student at the Savannah College of Art and Design in Georgia. Together they brainstormed and came up with the “Candy Chicks”: a group of characters, each a female scientist with her own personality, sense of style, hobbies and goals. There’s Alexis, who loves pink and enjoys the camaraderie that comes from working in a lab with colleagues; and Zoe, who loves black, plays rock guitar in her spare time and relishes the interactions of different chemicals in the lab. The Candy Chicks star in their own storybooks, which show each of the girls going on adventures and using science to solve challenges that arise along the way; the books end with do-it-yourself science experiments designed for girls to do at home, while wearing the accessories — glamorous goggles and colorful lab coats — that come packaged with it.
ALSO: If We Want More Women in Science, We’re Going to Have to Train Them. Here’s How to Do It
For now, the books and accessories, aimed at girls from kindergarten-age to third grade, are still in the prototype phase. LabCandy is currently operating on funding from YEI, family and friends, while applying for other grants and planning a crowdfunding campaign this summer. Through the LabCandy blog, early excitement about the project appears to be taking root among girls, parents and science teachers.
There’s criticism too, of course. Pavco-Giaccia has already heard people say that LabCandy trivializes science and girls by responding to one stereotype — the nerdy, old  male scientist — and replacing it with another: a frivolous girl who can only be tricked into engaging in serious issues with distractions like fashion. “That’s not what we’re saying at all,” Pavco-Giaccia says. “But I do think that there’s a real barrier in terms of letting girls think that science is an option. Sometimes science can look so scary and foreign from the outside that girls don’t even want to approach it. What we’re doing is making science more approachable and relatable. The goggles might get them there, but the science is what keeps them there.”
Pavco-Giaccia didn’t have jewel-encrusted eye gear when she attended the Potomac School in McLean, Va., but she had something vastly more important: strong female mentors. Mary Cahill, her sixth-grade science teacher, clearly loved her chosen field and conveyed her own excitement to her students. “Up until that point, all of my teachers had been male. I don’t know if I ever really consciously recognized that, but it was definitely a factor in my decision making,” Pavco-Giaccia recalls. “It made me feel that what they did was not something that I could do. But Ms. Cahill challenged me and she was enthusiastic, and suddenly science became not just a boy’s subject. It became my subject.”
Pavco-Giaccia still remembers the details of assignments from Ms. Cahill’s class. “She had a collection of sand from all these different beaches all over the world,” Pavco-Giaccia says, describing one of her favorite projects. “She would ask her old students to bring back sand from beaches they visited over vacation. We learned to use microscopes looking at all these different types of sand under the microscope. And we’d see how sand from all over the world looked different.”
MORE: Why Are These Female Scientists Tweeting Photos of Their Manicures?
Pavco-Giaccia continued to pursue hard science classes in high school at the Potomac School, under the guidance of her adviser, Denise Reitz. Ms. Reitz, also a science teacher, encouraged Pavco-Giaccia to apply for key summer internships, including those at a cancer lab at Georgetown University and in the Stanford lab of neuropharmocologist Dr. Bruce MacIver. The latter position became the unexpected catalyst for LabCandy, when Pavco-Giaccia’s blog post showing her custom goggles at the lab ignited the imaginations of other aspiring female scientists.
Pavco-Giaccia wants other young girls to feel the thrill she still experiences when she enters a lab, a feeling she first felt when she adopted a tree in Ms. Cahill’s class and observed and chronicled its changes over three months. Through LabCandy, Pavco-Giaccia hopes to make science not only accessible to girls, but fun and relatable too. She wants other young girls to see themselves reflected in the Candy Chicks, to defy the odds and get involved in science. “Throughout my whole science career, there just weren’t a lot of girls doing it,” Pavco-Giaccia says. “When I looked around at science fairs or camps, I didn’t see a lot of people who looked like me. It was a bit disorienting. And I love science, and I want to share it with other girls for them to love it too.”
When Pavco-Giaccia imagines future LabCandy consumers, she thinks of her cousin Ava, a precocious 6-year-old known to speak her mind. When Ava pulled on a pair of the prototype goggles, adjusting them to fit her head, she looked in the mirror, admired her reflection, then furrowed her brow. “Is this what a scientist looks like?” she asked her cousin.

“Yes,” Pavco-Giaccia said with a smile. “That is exactly what a scientist looks like.”

Update: April 7, 2014
On April 6, 2014, 18 girls from public middle schools in New Haven, Conn., joined the founder of LabCandy for an afternoon of science organized by Yale undergraduates Noah Remnick and Kate Wiener. With the support of NationSwell readers who donated to a Rally campaign, the event served as an on campus social action initiative to mobilize support around the LabCandy model for making science cool. Participants decorated lab goggles and learned from Yale science majors and Yale professor Laurie Santos at the planetarium.

One Small Tweak Made a World of Difference in This Computer Science Class

Something revolutionary happened last spring at the University of California Berkeley. For the first time ever, as far as digitized records indicate, more women than men enrolled in Professor Dan Garcia’s introductory computer science course, “Beauty and Joy of Computing.” Men have long outnumbered women in computer science majors, earning 81.8% of the bachelor’s degrees according to a 2010 National Science Foundation report, and are far more represented in careers in the field. So professors at Berkeley, Stanford, and elsewhere have retooled their computer science classes, especially introductory ones, with the hopes of attracting more women to them.
Garcia told Kristen V. Brown of the San Francisco Chronicle that he conceived his computer science class for non majors as being more than “just programming,” and he made it “kind of right-brained as well.”
Sumer Mohammed took Garcia’s course without plans to major in computer science, and the class changed her mind. She’s now an electrical engineering and computer science major. In recent years Berkeley and Stanford have about doubled their computer science enrollment among women, who now comprise 21% of the students in this discipline at each school.

This Little Girl’s Science Experiment Led Her to Question a Standard Farming Practice

Nine-year-old Elise wanted to do a science experiment to find out how long it would take a sweet potato to grow vines. So she went to the grocery store with her grandmother, bought a sweet potato, and put it in a glass of water. But, as she explains in this video posted to YouTube by Suzanne Bartlett, no matter how long she left the sweet potato in the water, it wouldn’t sprout vines, even after she tried multiple potatoes.
Elise says, “We talked to the produce man at the store, and he said, ‘Well, these will never grow vines. At the farm, they spray them with a chemical called Bud Nip. You should try one of our organic sweet potatoes.” She did, and in a month it sprouted vines. She tried the experiment with an organic sweet potato from another grocery store, and it worked too. Before she knew it, a simple science experiment had turned into an important lesson about pesticides for the precocious little girl.
But Elise didn’t stop there—she continued her research, reading up on Bud Nip, also known as Chlorpropham, and learned that it’s routinely applied to onions, blueberries, tomatoes, and other produce, and that some experiments have shown it to cause tumors in animals. According to the Pesticide Information Project, long-term exposure “may cause adverse reproductive effects.” Elise concludes her video with the question, “Which potato would you rather eat?”
