This Eco Tech Will Double the Life of Your Fruits and Veggies

How many untouched bunches of celery have seeped into rot at the back of your fridge? How many expensive pints of strawberries turned moldy almost immediately after you bought them? How many avocados have become unsalvageable because you missed the short window of ripeness?

Food waste is a massive problem. It’s costing our health, our wallets, and our environment.?Americans waste an astonishing?150,000?tons of food every single day (about 1 pound of food per person). The UN estimates that food waste costs $2.6 trillion globally per year, and produce is a major culprit.

That?s where Apeel Sciences comes in.

Fighting Food Waste with Food Waste

Apeel Sciences is a California-based food tech startup with a mission to reduce food waste, and they’ve made some serious headway. They claim to have developed a way to actually double the shelf life of fruits and veggies?even avocados.

According to?CNBC, ?The company’s technology basically works like this: Plant materials that are left behind on the farm (leaves and peels, for instance) are blended, and then lipid molecules are extracted. The resulting powder is then turned into a liquid that is sprayed on produce; fruits and vegetables can also be dipped into the solution.”

Apeel has created an edible, colorless plant-based powder which fortifies produce skin and slows the rate of water loss and oxidation. As a result, it significantly extends the ripening process. Apeel-treated fruits and veggies are?less likely to get mushy in the deep chasms of your fridge, but on a larger scale, this?also means that grocery stores will potentially throw away significantly less rotting produce.

Here’s a video posted by Apeel Sciences showing their produce in action.

Working?with Del Rey Avocado and Eco Farms, Apeel has launched its first slow-ripe avocados at Costco locations nationwide as well as Harps location in the Midwest.

They are also planning to launch?Apeel citrus, with hopes?to expand to other fruits and veggies soon.?In testing, they have successfully extended the life of dozens of plant foods, including:

bananas
berries
citrus fruits
stone fruits
peppers
asparagus

Currently, Apeel’s products are only available to?suppliers and retailers on the production end, but the company hopes to eventually make its product available direct to consumers as well.

Beyond Food Waste

While this is potentially a massive?win for minimizing food waste and saving money on groceries, this technology also has the capacity to improve the diets of those who live in hard-to-reach areas of the country.

People?living in food deserts, where fresh and affordable food is a rarity, tend to be?forced?to rely on highly?processed foods. Apeel’s use in the produce industry?could potentially?make?fresh foods more accessible by extending shelf life.

It’s all about using nature to heal our broken food system.

According the Apeel?s head of marketing Michelle Masek, “Every piece of produce, every fruit, every plant already has a peel. And that peel is already doing what it needs to do to keep the fruit fresh. Instead of making new chemicals in a lab, let’s use the same ingredients that nature gives us time and time again to add a little extra Apeel to produce.”

“A fact-filled, fun, and enlightened peek into our minds and hearts.” —Daniel Goleman, author of Emotional Intelligence In this startling study of human emotion, Dacher Keltner investigates an unanswered question of human evolution: If humans are hardwired to lead lives that are "nasty, brutish, and short," why have we evolved with positive emotions like gratitude, amusement, awe, and compassion that promote ethical action and cooperative societies? Illustrated with more than fifty photographs of human emotions, Born to Be Good takes us on a journey through scientific discovery, personal narrative, and Eastern philosophy. Positive emotions, Keltner finds, lie at the core of human nature and shape our everyday behavior—and they just may be the key to understanding how we can live our lives better.

The Origins of Creativity – Edward O. Wilson

READ GREEN WITH E-BOOKS

The Origins of Creativity

Edward O. Wilson

Genre: Life Sciences

Price: $11.99

Publish Date: October 3, 2017

Publisher: Liveright

Seller: W. W. Norton


An eloquent exploration of creativity, The Origins of Creativity grapples with the question of how this uniquely human expression—so central to our identity as individuals and, collectively, as a species—came about and how it has manifested itself throughout the history of our species. In this profound and lyrical book, one of our most celebrated biologists offers a sweeping examination of the relationship between the humanities and the sciences: what they offer to each other, how they can be united, and where they still fall short. Both endeavours, Edward O. Wilson reveals, have their roots in human creativity—the defining trait of our species. Reflecting on the deepest origins of language, storytelling, and art, Wilson demonstrates how creativity began not ten thousand years ago, as we have long assumed, but over one hundred thousand years ago in the Paleolithic age. Chronicling this evolution of creativity from primate ancestors to humans, The Origins of Creativity shows how the humanities, spurred on by the invention of language, have played a largely unexamined role in defining our species. And in doing so, Wilson explores what we can learn about human nature from a surprising range of creative endeavors—the instinct to create gardens, the use of metaphors and irony in speech, and the power of music and song. Our achievements in science and the humanities, Wilson notes, make us uniquely advanced as a species, but also give us the potential to be supremely dangerous, most worryingly in our abuse of the planet. The humanities in particular suffer from a kind of anthropomorphism, encumbered by a belief that we are the only species among millions that seem to matter, yet Wilson optimistically reveals how researchers will have to address this parlous situation by pushing further into the realm of science, especially fields such as evolutionary biology, neuroscience, and anthropology. With eloquence and humanity, Wilson calls for a transformational "Third Enlightenment," in which the blending of these endeavors will give us a deeper understanding of the human condition and our crucial relationship with the natural world.

Trump halted a study of coal’s health effects in Appalachia

This story was originally published by Mother Jones and is reproduced here as part of the Climate Desk collaboration.

The Trump administration has told the National Academy of Sciences to stop working on a study about the potential health risks for people living near mountaintop coal-removing sites in Central Appalachia.

“Everyone knows there are major health risks living near mountaintop removal coal mining sites,” Bill Price, the senior Appalachia organizer at the Sierra Club, said in a statement. “It’s infuriating that Trump would halt this study on the health effects of mountaintop removal coal mining, research that people in Appalachia have been demanding for years.”

In 2014, a West Virginia University study found that dust from mountaintop removal coal-mining sites was linked to increased incidences of lung cancer. The following year, the state formally asked the Obama administration for help in studying these health effects, and in 2016, the Office of Surface Mining Reclamation and Enforcement (OSMRE) gave the NAS $1 million to determine the human health effects for people living near coal mine operations.

But last week, in an Aug. 18 letter to the National Academy of Sciences (NAS), the OSMRE said that the Department of the Interior has begun an agency-wide review of all its grants and cooperative agreements that exceed $100,000, as part of the department’s “changing budget situation” and that the agency should halt all work on the study. The NAS says that it is ready to resume work on the study when the review is complete.

“Communities living with daily health threats were counting on finally getting the full story from the professionals at the National Academies of Science,” Price said. “To take that away without warning or adequate reason is beyond heartless.”

Not only can coal have an impact on public health, burning it releases carbon dioxide, a greenhouse gas that contributes to global warming. Nonetheless, the Trump administration has been aligned with climate skeptics, and throughout his campaign and presidency, Trump expressed support for the coal industry.

When he announced a new agenda for the EPA, Administrator Scott Pruitt told a group of coal miners that “the coal industry was nearly devastated by years of regulatory overreach, but with new direction from President Trump, we are helping to turn things around for these miners.” At an Iowa rally in June, Trump promised to put coal miners back to work. “We’ve ended the war on clean, beautiful coal,” he said.

Bill Price, from the Sierra Club, says that revoking this study demonstrates the administration’s real priorities when it comes to coal. “It appears that the only people Trump cares about in Appalachia are coal executives,” he wrote, “not the people who’ve lived and worked here for generations.”

"A glorious book . . . A spirited defense of science . . . From the first page to the last, this book is a manifesto for clear thought." *Los Angeles Times "POWERFUL . . . A stirring defense of informed rationality. . . Rich in surprising information and beautiful writing." *The Washington Post Book World How can we make intelligent decisions about our increasingly technology-driven lives if we don't understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions. Casting a wide net through history and culture, Sagan examines and authoritatively debunks such celebrated fallacies of the past as witchcraft, faith healing, demons, and UFOs. And yet, disturbingly, in today's so-called information age, pseudoscience is burgeoning with stories of alien abduction, channeling past lives, and communal hallucinations commanding growing attention and respect. As Sagan demonstrates with lucid eloquence, the siren song of unreason is not just a cultural wrong turn but a dangerous plunge into darkness that threatens our most basic freedoms.

It’s happening: Climate change starts disappearing from government websites.

That’s according to a new study published in Proceedings of the National Academy of Sciences.

You’re probably used to hearing about how denser cities cut transportation emissions, thanks to reduced driving. This study looks at a different impact: how density affects greenhouse gas emissions from buildings.

The researchers projected emissions from buildings under different potential urban densities between now and 2050. They found that denser development patterns lead to lower emissions because people live and work in smaller units that consume less energy. Attached buildings are also more efficient for heating and cooling.

So the PNAS study finds that greater density has the potential to substantially reduce building emissions, more so than other efforts to improve energy efficiency like better weather-proofing.

Unfortunately, global trends are moving in the wrong direction. Cities around the world are growing, but at the same time, urban density is decreasing, as cars enable cities and their suburbs to sprawl outwards.

Governments can adopt policies to make their cities and towns denser, and they’ll need to — not just in the relatively sprawling cities of North America and Europe, but in the fast-growing cities of Asia and the rest of the developing world.

Science Says People Who Take Selfies Are Happier Than People Who Don’t

Ever start feeling yourself after taking a couple of selfies? Well, you’re not the only one. According to a study recently published in Psychology of Well-Being, selfies can actually make people feel confident and happy—provided they take them when smiling.

“Our research showed that practicing exercises that can promote happiness via smartphone picture taking and sharing can lead to increased positive feelings for those who engage in it,” said lead author and informatics scholar Yu Chen. “This is particularly useful information for returning college students to be aware of, since they face many sources of pressure.”

Using smartphone photo technology, researchers in the Donald Bren School of Information and Computer Sciences at the University of California-Irvine asked 41 students to take selfies over the course of a month. Students were randomly divided into three groups. One group was asked to take daily selfies while smiling; the second group took pictures of something that made them happy; and the third group took pictures of something they thought would make someone else happy, which they then shared with that person.

Researchers collected 2,897 mood measures—comfortable, reflective, and appreciative—and measured students’ emotional states over time. They found that students in all groups experienced increased good feelings. The selfie group was reported to feel more confident and comfortable over the course of the study, and those who took images to make other people happy felt happy themselves, noting the personal connection helped relieve stress.

“You see a lot of reports in the media about the negative impacts of technology use, and we look very carefully at these issues here at UCI,” said Gloria Mark, senior author and informatics professor. “But there have been expanded efforts over the past decade to study what’s become known as ‘positive computing,’ and I think this study shows that sometimes our gadgets can offer benefits to users.”

So go ahead, smile, and selfie away!

Cholera could make a comeback, thanks to climate change

Bacteria to the future

Cholera could make a comeback, thanks to climate change

By on Aug 9, 2016Share

The ’90s are back! The 1890s, that is, when handlebar mustaches were hot and cholera took hundreds of thousands lives across the globe. Over a century later, both look to be making a resurgence — the former thanks to Brooklyn scenesters and the latter thanks to climate change.

According to a new study in Proceedings of the National Academy of Sciences, the waterborne bacteria that causes cholera, Vibrio, is on the rise due to warming ocean temperatures. Researchers measured Vibrio bacteria in plankton samples collected between 1958 and 2011, a period during which the surface temperature of the oceans increased by about 1.5 degrees Celsius, and found that as the temperatures got higher, so did the number of lethal bacteria.

Currently, cholera kills about 142,000 people each year worldwide — a number that could increase with climate change. People in developed nations are not at too much risk, as the disease can be mitigated with good water management. “As long as those treatment facilities remain intact, I don’t think we’re going to see outbreaks of cholera [in Europe and the United States] again,” study coauthor Rita Colwell told Scientific American

But the same cannot be said for the rest of the world. People in less-developed nations with poor sanitation systems are especially vulnerable.

The weather is throwing thunderstorm tantrums

Jerkstorm alert

The weather is throwing thunderstorm tantrums

By on Jun 21, 2016 5:05 amShare

Good news for thunderstorms that get a kick out of ganging up, flooding a few billion dollars worth of real estate, and tearing roofs off buildings: the climate is working in your favor.

Hoo boy, is it ever. Burning wood, coal, and oil generate fine aerosol particles that create perfect conditions for thunderstorm ragers, according to a new study published in the Proceedings of the National Academy of Sciences. Aerosol particles do this by delaying rainfall from anything from a few hours to a full day, causing clouds to grow bigger and bigger until the resulting storm is a puffed-up, roided-out monster.

Scientists have suspected the connection between aerosols and crazy weather for a while. Aerosol particles from Chinese factories, for example, have been implicated in the frat party storms of the Pacific Northwest. What makes this study different is its scale. The research team looked at satellite data from 2,430 different cloud systems gathered from geostationary satellites that track the same spot on the Earth’s surface all day, instead of just flying over the planet a couple of times the way other weather satellites do.

Think of these thunderstorms as tantrums that the weather is going to throw with more and more intensity until we get the hang of making energy without throwing fine particulate matter into the atmosphere. Even then storms won’t go away entirely, but at least they’ll be tearing up the town a lot less often.
