Researchers grow heart tissue on spinach leaves

In this sequence, a spinach leaf is stripped of its plant cells, a process called decellularization, using a detergent. The process leaves behind the leaf’s vasculature. Researchers at Worcester Polytechnic Institute (WPI) were able to culture beating human heart cells on such decelluralized leaves. Credit: Worcester Polytechnic Institute

Researchers face a fundamental challenge as they seek to scale up human tissue regeneration from small lab samples to full-size tissues, bones, even whole organs to implant in people to treat disease or traumatic injuries: how to establish a vascular system that delivers blood deep into the developing tissue.

Current bioengineering techniques, including 3-D printing, can’t fabricate the branching network of blood vessels down to the capillary scale that are required to deliver the oxygen, nutrients and essential molecules required for proper tissue growth. To solve this problem, a multidisciplinary research team at Worcester Polytechnic Institute (WPI), the University of Wisconsin-Madison, and Arkansas State University-Jonesboro have successfully turned to plants. They report their initial findings in the paper “Crossing kingdoms: Using decelluralized plants as perfusable tissue engineering scaffolds” published online in advance of the May 2017 issue of the journal Biomaterials.

‘Organic’ water claims in Australia are misleading

Bottled water labeled “organic.”

The bottled water industry in Australia has finally gone too far.  Seven makers were forced to drop claims that their product “organic” while another chose to remove their brand from sale.  The manufacturers got rid of their spin under threat of enforcement action from the Australian Competition and Consumer Commission, which is cracking down on misleading “credence” claims.

Doubt cast on advantages of organic produce and meat

Researchers say organic foods are no more nutritious and no less likely to be contaminated.

Are organic fruits and vegetables more nutritious than conventional fruits and vegetables?  Maybe — or maybe not.

Scientists at Stanford University have weighed in on the “maybe not” side of the debate after an extensive examination of four decades of research comparing organic and conventional foods.

Are health food stores making you fat?

Health food stores use every trick they learn from conventional grocery stores to get you to open your wallet.

The food business is still business, including those claiming to be superior because they are selling organic or ‘health’ products.  They exist to lure you in and make you buy as much stuff as possible.

Scientists produce biofuel from recycled newspapers

carscouldrun

Tulane University has applied for a patent for a method to produce the biofuel butanol from organic material.

Scientists have found one way that old-fashioned newspaper beats the internet. Tulane University scientists have discovered a novel bacterial strain, dubbed “TU-103,” that can use paper to produce butanol, a biofuel that can serve as a substitute for gasoline. They are currently experimenting with old editions of the Times Picayune, New Orleans’ venerable daily newspaper, with great success.

Prenatal Exposure to Pesticides Leads to Diminished IQ’s in Children

prenatal pesticides

The study found some of the risks that pesticides were already known to pose to children, including ADHD and learning difficulties.

It was reported this week by the Environmental Working Group that three studies published simultaneously all came to the same eye-opening conclusion.  The conclusion was prenatal exposure to organophosphate pesticides leads to diminished IQs in children between the ages of 6 and 9.

Krestel – The First Car Built Out of Hemp

Krestel

Marijuana’s fibrous cousin hemp has a long history with auto makers. in 1941 Henry Ford unveiled a car body made primarily out of organic fibers, hemp included. seventy years later, the world’s first production-ready biocomposite electric car—with hemp as the “bio”—will finally hit the streets. The Kestrel, a three-door hatchback, is made of a “hemp composite as strong as the fiberglass in boats, yet incredibly lightweight,” says Nathan Armstrong, the president of Motive industries, Kestrel’s manufacturer.

Brush Your Teeth with THIS Stick

THIS tooth brush1234

THIS is it for your teeth!

A miswak is a tooth cleaning stick made from the Salvadora persica tree. It’s traditionally used in Pakistan, India, and the Middle East in place of a modern plastic toothbrush. The bristles inside the plant, once exposed by cutting across the stem, are effective as a cleaning instrument. Leen Sadder, a design student, decided to make a modern version..

Monsanto Wins Big and Consumers Again Get Screwed

monsanto_control_food

What a great time to become a vegan!

Agriculture Secretary Tom Vilsack has officially approved the unregulated planting of Monsanto’s genetically engineered alfalfa. In a move that will undoubtedly set a precedent for what comes next (namely, the question of whether or not to deregulate GE sugarbeets) Vilsack did nothing more, and nothing less than obliterate our choice as organic consumers to be assured that we are avoiding genetically modified organisms in our food…

Milk From Organic Cattle Less Fatty Than Ordinary Milk

Organic milk is better for your health.

Milk from organic cattle that eat a fresh grass diet is consistently better for your health, a new study claims. Researchers have found that organic milk generally contained less saturated fat and more good fatty acids than milk produced at intensive commercial dairy farms.

Hydrogenase: Self-sufficient Organic Airship

Hydrogenase

Vincent Callebaut’s latest project, Hydrogenase, aims to create a self-sufficient organic airship.   This conceptual transport system would be comprised of airships that produce biofuel from seaweed.  The project draws its inspiration from nature, as well as from the qualities of its materials and its self-manufacturing processes.  (pics)
