60-Day Bread Cuts Waste: DNews Nugget

Dnews-nuggets-278x225Longer-Lasting Bread: The average loaf of grocery story bread will start to go moldy in 10 days. But a U.S. company has devised a technique that it says can extend a loaf's freshness by up to 60 days.

The technique developed at Texas Tech University in Lubbock involves zapping the bread in a microwave array. The microwaves kill spores inside the bread that would normally develop into mold.

Food waste is a huge problem in the United States, where it's estimated the average family ends up tossing out about 40 percent of the food they buy. Bread is often one of the items that ends up in the garbage due to its short shelf life.

The new zapping technique could not only reduce that waste, the researchers say it could also help bread manufacturers use less preservatives. Currently many bread manufacturers add preservatives to their products to extend the bread's shelf life. They then add extra chemicals to mask the taste of the preservatives. By zapping the bread, it may be possible to avoid using preservatives altogether.

The technique can also be used to extend the freshness of other foods, including fresh turkey and many fruits and vegetables.

Pelt Yourself With Laboratory Leather

Leather-lab-622

Former porn star Jenna Jameson's "Pleather Yourself" photo shoot was a provocative, anti-leather component of PETA's NSFW initiative last summer. However, the animal rights group might not have to resort to such gimmicky tactics in the future, now that laboratory leather is on the horizon.

Modern Meadow is a company that is developing new approaches to meat and leather production. In August, Breakout Labs, a branch of PayPal cofounder Peter Thiel's foundation, awarded the company a grant to bioprint meat and leather.

BLOG: PETA's 'Porn' Site Now Live

"Our emphasis first is not on meat, it's on leather," cofounder and CEO Andras Forgacs told Txchnologist. "The main reason is that, technically, skin is a simpler structure than meat, making it easier to produce."

Though still in the development stage, Modern Meadow envisions doing so by first extracting, isolating and even genetically modifying cells from live animals. Next, cells would be proliferated in a bioreactor and lumped together to create aggregated spheres of cells. The aggregates would then be put together in layers, allowing them to fuse together, potentially by way of 3-D printing.

Then the bioassembled cells would be put into a bioreactor and given time to mature.

"We create the embryonic precursor and, in the bioreactor, apply physical cues to let nature take over," Forgacs said. "This stimulates collagen production in the case of the cells that will become leather and muscle growth in what will become meat."

NEWS: Want to Save Earth? Cut Out Meat

Finally, after several weeks of cells being deprived of food, skin tissue turns to hide while the muscle and fat tissue are harvested for food. Being that the hides are hairless and don't have a tough outer skin, the tanning process is condensed, thus decreasing the amount of toxic chemicals needed for the operation.

"Nothing we're doing requires a scientific leap of faith," Forgacs said. "There's no science we're using that we're not confident with. This isn't about scientific risks, it's about engineering challenges."

Geoengineering Soaring To New Heights

Geoengineering-622

I come from a pasty Norwegian breed. In my younger, devil-may-care years, I used to scoff at wearing sunscreen with the belief that the quickest way to skin cancer a bronzed bod was roasting myself at the beach without a drop of SPF in sight.

Not any more. I've read the reports and even witnessed my dad, who has a similar complexion, receive skin test results that came back malignant. Now I'm a liberal sunscreen applier when I go out. Plus, sunscreen makes you smell like you just came from the beach, and I like that. It's my new cologne.

PHOTOS: Wind Power Without the Blades

In some ways, our planet is of a pasty breed and needs adequate protection from the sun, too. Many scientists say our planet is getting hotter, compliments of us industrious folks who call Earth home.

Here in Missouri, the grass is brown and the leaves on the trees are wilted. The USDA has declared every county in the state as disaster area because of the drought. Just a random old hot-and-dry summer or the consequences of human-induced climate change?

Well, a couple of Harvard engineers aren't waiting around for your opinion. David Keith and James Anderson are preparing to spray thousands of tons of sun-reflecting sulphate aerosols into the sky over Fort Sumner, New Mexico. Why? They believe the particles will reflect the sun's rays back into space and help lower the Earth's temperature.

HOWSTUFFWORKS: Will a Drought Affect the Price of Ethanol?

They plan to do so by using a balloon flying 80,000 feet above the Fort Sumner. The geoengineering project aims to mimic the effects of volcanoes spewing sulphuric ash into the air.

Keith says the project could be an inexpensive way to slow down climate change, however other scientists warn that his methods could have dire effects on the planet's weather systems and food supplies. Environmentalists fear Keith's method is merely a stopgap that undermines efforts to accurately fight climate change by reducing carbon emissions.

The experiment will take place in a year and see the release of tens or hundreds of kilograms of particles that, besides measuring impacts on ozone chemistry, will also find ways to make the sulphate aerosols the correct size.

"The objective is not to alter the climate, but simply to probe the processes at a micro scale," Keith told the Guardian. "The direct risk is very small.

"BLOG: Could Laser Beams Induce Rain?

However, Pat Mooney, executive director of the technology watchdog ETC Group, begs to differ:

"Impacts include the potential for further damage to the ozone layer, and disruption of rainfall, particularly in tropical and subtropical regions – potentially threatening the food supplies of billions of people. It will do nothing to decrease levels of greenhouse gases in the atmosphere or halt ocean acidification. And solar geoengineering is likely to increase the risk of climate-related international conflict -- given that the modelling to date shows it poses greater risks to the global south."

What say you? Let the balloon fly or pop it with a BB gun before lifts off?

Reusable Water System For Beverage Producers

Bottle-water-622
This summer, parts of the Midwest and West are experiencing terrible drought, and worldwide fresh sources of water are declining. A new technology unveiled by GE could potentially saves millions of gallons of water a day that would otherwise go down the drain at beverage bottling companies. The technology is a water purifying program called AquaSel, and in initial tests at an Asian bottling plant, it reduced wasted water to less than 1 percent of the total amount brought in.

BLOG: Future Displays Made of Water and Air

To use local water for bottling beverages, companies typically purify it using a process called reverse osmosis, which forces water through a membrane to remove unwanted salts. Normally after using reverse osmosis, the company can use 80 percent of that water for beverage production. The remaining 20 percent contains salt concentrations and is called brine, which is dumped as waste.

GE’s system treats the waste water using a technology called a non-thermal brine concentrator (NTBC). It contains a component that removes salt from the brine and then uses a chemical and mechanical process on the remaining solution to precipitate salt crystals out of it.

The process has significantly reduced the amount of freshwater needed by 10 to 20 percent. That amount may seem small, but when it amounts to millions of gallons saved annually, it can make a huge difference in how water is used and conserved all over the world.

'Smart Village' Sets Example for Poverty Relief

Rimbunan Kaseh Pulau Manis (1)

A model village in Mayalsia is changing the way communities tackle poverty. Rimbunan Kaseh, a rural village sitting on 30 acres of land near Kuala Lumpur, was built to serve as an example of how to address rural poverty issues by promoting environmental sustainability with technology. The project was detailed at this year's Global Science and Innovation Advisory Council meeting in San Jose, Calif. The GSIAC is made up of international leaders from several countries to find ways to build sustainability and a stronger economy for the Asian country.

BLOG: Movie Frames Saved to Atomic Vapor

The community offers education, training and recreational facilities, as well as 100 affordable post- MIGHTconsumer material built homes, selling from $16,000 to $20,000. A closed-loop agriculture system is a big part of the community, providing food and income for its residents. ‘Closed loop’ means that everything in the community is inter-connected, for example: An aqua-culture system raises fish for a protein-rich food supply, waste from the fishtanks is then used to irrigate plants to grow fresh produce. The produce is grown in hydroponic pots that can detect soil moisture, which makes it easer to water plants accurately without wasting water. All of these processes come together to provide reliable food supply and augment resident’s income by $400 to $650 a month. Sustainability is also supported with the communities solar power capabilities, biomass energy and mini-hydro electricity.

Ribunan Kaseh offers everything typical communities do like schools, playgrounds and places of worship, with a high-tech twist. Educational facilities are equipped with 4G Internet service that supports e-learning and e-health services. Ellis Rubenstein, President and CEO of the New York Academy of Sciences, said at the GSIAC meeting, “Integrated smart communities could transform services available to Malaysia's citizenry while creating thousands of jobs, complementing GSIAC's unprecedented alliance to improve education in that country at every level from cradle to career.”

More “smart villages” are planned for the area, with up to 12 sites in the near future. While it’s centralized to Malaysia for now, this example could set a new precedent in creating change for people experiencing poverty all over the world.

Pizza Vending Machines Coming to U.S.

Letspizza-3

It's been a banner week for vending machines. First, we told you about Rugbeer, the Cerveza Salta vending machine that dishes out beer if you slam into it hard enough. Now comes word of a vending machine with a dish just as tasty: pizza.

PHOTOS: Video Games Fails

After some initial success in Europe, Italian Claudio Torghel is getting ready to roll out his Let's Pizza vending machines in the United States. Since you're already getting your flicks from that Redbox by the grocery store, you might as well top off movie night with a fresh pizza pie.

Fresh, you balk? Yes, fresh. Let's Pizza machines say they're a cut above factory farmed pizzas. Here's the fresh factor: After customers pay, they begin by selecting one of four kinds of pizza available. Inside, a machine mixes flour and water together and kneads it into dough, which is then rolled flat. After toppings are added, the pizza is cooked in an infrared oven and dispensed in a take-home box. Voila, your very own 10.5-inch pie in under three minutes.

BLOG: Want Beer? Tackle This Vending Machine

Ingredients are not frozen, but kept refrigerated in single-serving packages until needed. Each machine has enough ingredients for 100 pizzas before it needs restocking.

The vending machines are expected to debut later this year and the suggested price is $5.95 per pizza.

PETA's 'Porn' Site Now Live

Peta-622


Now that we've got you here, let us turn you on to what we're really about.

So says the banner that greets you when you log on to PETA's new NSFW website. Back in September, we told you how the animal rights advocacy group was planning to launch a XXX domain in effort to lure people with risque images then confront them with graphic footage of animal cruelty. 

BLOG: Robot Prostitutes, The Future Of Sex Tourism

Well all you lascivious lads and ladies, peta.xxx is live. Not only that, they've enlisted some of the biggest names in the porn adult entertainment industry to help them do so.

"This site has some of the most explicit and jaw-dropping videos I have ever seen, and that says a lot," says iconic, harmonica-playing porn star Ron Jeremy in the site's welcome video. That's right, Ron Jeremy playing a harmonica.

"Peta.xxx is a lot more than just sex appeal," Jeremy continues against schmaltzy-saxophone background music. "You may get a little more than you bargin for. So sit back, relax and allow us to turn you on. You may get the ride of you life and you will never be the same again."

Other high-profile names baring themselves for the site include Jenna Jameson who invites you to "Discover the pleasure of pleather." Sasha Grey, now a serious actress, also reminds you that "too much sex can be a bad thing" and, oh yeah, "have your cats and dogs spayed and neutered."

Visitors to the site are given a variety of links to click on. The 'Sexy Photos' link includes various images of scantily clad vixens publicly stumping for PETA while the 'Sex Tips' link makes the case that vegetarians make better lovers.

BLOG: PETA.XXX To Feature Nude Activists

However, the 'Hardcore Videos' link is the most extreme. And by 'hardcore,' PETA means videos of animal cruelty that are "so 'offensive' that no TV stations have dared to run them." It's here where the site's bait-and-switch is best achieved. Those seeking videos of the primal act are instead given videos of what PETA considers the primal sin.

Videos include those of slaughter houses, abused circus animals and giggling lab rats, as well as lizards being decapitated in Indonesia.

Think PETA compromised their ethics by teaming up with the smut business? Here's their defense:

PETA's mission is to put an end to animal suffering, and we use every available opportunity to spread this message -- we always have, and we always will. Unfortunately, this is not always an easy task. Unlike our opposition, which is mostly made up of wealthy industries and corporations, PETA must rely on getting free "advertising" through media coverage. It's a safe bet that many visitors to PETA.xxx didn't set out to learn about how animals are mercilessly slaughtered on today's factory farms; understandably, such topics are convenient to ignore. That's why PETA must make our message impossible to forget -- and launching a website with a .xxx domain name is one way that we can achieve that goal.

Rewrite Future Fortunes With Cookie Maker

FPSBFCM40_13_5004_14_43578

I kid you not. I have a friend who, besides his love for flying balsa wood airplanes, has an autographed George Foreman grill. I'm talking about an honest-to-God autograph, Sharpie-signed by Big George himself -- not the cheap knock-off signature that adorns each grill.

This anecdote certainly speaks volumes about the kinds of friends I keep, but on a broader scale, it suggests something more. I hate to get all philosophical about gimmicky kitchen cookers, but that a grown man would keep an autographed George Foreman grill year after year confirms the following: We love our kitschy fold-down, countertop appliances like nothing else.

BLOG: Top Strange and Impractical Techs From CES 2012

I mean, where would the modern kitchen be without such tools of culinary brilliance as The Hamilton Beach Quesadilla Maker, the Presto Pizzazz Pizza Cooker and the debonair, silver fox of them all, the Belgium Waffle Maker?

Well, get ready to crowd your countertop with even more crockery because Sunbeam's Fortune Cookie Maker is going to rewrite your future, cookie by cookie, from the inside out.

The device comes with everything you need to fill your homemade fortune cookies with the craftiest, snarkiest and most twisted fortunes your sardonic little mind can imagine. The appliance boasts a nonstick interior surface, a batter scoop, a spatula, a pen for writing fortunes and cookie-removal tongs (which just so happens to be the name of my new folktronica band).

BLOG: Behold the Golden Age of Ice Cream

Fortunately, your cookie-making kit also comes with a recipe for fortune cookie batter and instructions so you don't burn down your house.

Sunbeam, if you're looking for someone to endorse your Fortune Cookie Maker, I nominate my balsa-flying friend as your pitchman. He's a charming fellow, is good with words and has a signature like a lightning bolt, so he'd be the perfect candidate.

Fruit Labels Dissolve Into Organic Soap

Wash-label-apple-622


As the preferred gift of teacher's pets and the daily, apotropaic fruit that keeps doctors away, apples have somewhat of a goody-two shoes reputation. But actually, they've got a dirty side to them. Just ask these guys who recently ranked apples atop their list of fruits and veggies most contaminated with pesticides.

PHOTOS: Life In A Drop of Water

And those pesky stickers that always leave a gluey residue if you can even pick them off with your fingernail...no wonder apples got biblically tagged as the forbidden fruit.

Enter Scott Amron, a New York-based electrical engineer, who has an idea that could literally clean up the apple's act. His Fruitwash stickers, when put under the water faucet, would dissolve into organic fruit soap that removes pesticides, fungicides and that annoying water-resistant wax.

"I've always been discontent with fruit labels and felt they could do more than just display product info and be difficult to peel off," Amron told Gizmag. "We buy, wash and eat fruit. So, the wash step was the next thing the label should help with."

Amron is keeping his Fruitwash ingredients under wraps, be he said they're designed to "outlast the fruit they label."

BLOG: Apple's Genetic Material Is A Delicious Find

He added: The "best thing is the labels help make the fruit cleaner. And, there's no label to peel off and throw away unless you choose to peel the label off and throw it away."

Amron Experimental is currently selling a 10 percent stake in the Fruitwash Label's patents and hopes to market the soapy stickers within the next six to nine months.

Did We Get Duped by the Poop Burger Story?

UPDATE: We think we may have gotten duped! Like many other webites, we picked up on the story below that a Japanese researcher had found a way to turn human feces into an edible protein. One of our commenters on Facebook suggested that this story was a hoax and after some investigation, we think he might be right. We emailed the researcher for clarification, but have not yet heard back. But in the meantime, we did find this piece on Salon by Justin Elliot, who traced the origin of this story back to a Youtube video and also found several similar headlines that popped up online in the 1990s. We'll let you know if we hear back from the researcher. In the meantime, our apologies.

Steak-556

We're all familiar with what you do if life hands you a lemon. You make lemonade, right? But what if life literally hands you a turd? Well, if you're Japanese researcher, Mitsuyuki Ikeda, you do this: create an edible steak made from human feces.

We've previously reported on some colorful bowel movements, but this bowel-to-plate movement is way beyond colorful. In fact, it's almost beyond the pale. However, once your dry-heaves subside, what's even more absurdly stomach-churning is this idea is not only plausible, its already been taste-tested.

When Tokyo Sewage approached Mitsuyuki Ikeda, a researcher from the Okayama Laboratory, and asked him to explore potential uses for an overabundance of sewage mud, Ikeda found that, because of all the bacteria, the mud contained large amounts of proteins.

WIDE ANGLE: Poo Power

Ikeda and his team isolated those proteins, combined them with a reaction enhancer and put it in an exploder, thereby creating le cuisine de merde. The lab-grown steak is made from 63 percent proteins, 25 percent carbohydrates, 3 percent lipids, 9 percent minerals (and 100 percent you've-got-to-be-kidding-me). Researchers enhanced the flavor with soy protein and used red coloring to give the poo-burger that appetizing, meaty charm. According to DigitalTrends, initial taste-tasters have said the butt steaks even tastes like beef.

But is this meat safe?

Experts say, in theory, yes. But to kill any toxic pathogens, the meat must obviously be cooked.

WIDE ANGLE: Tissue Engineering

"In the food safety world we say, 'don't eat poop," Douglas Powell, a professor of food safety at Kansas State University, told MyHealthNewsDaily. "But if you're going to, make sure it's cooked."

Powel did say there was a potential for cross contamination in the lab where the bowel loaf was developed, but said the idea in not that different from eating vegetables that have been fertilized with manure or other excrement.

"Theoretically, there's nothing wrong with this," Powell added."It could be quite safe to eat, but I'm sure there's a yuck factor there."

Bon appétit!
