3D-printed ovaries let infertile mice give birth

Comments Off on 3D-printed ovaries let infertile mice give birth

Three-dimensionally printed organs are pretty old hat by now. But while the technology has been applied to everything from artificial ears to replacement brain tissue , working ovaries have been outside the realm of possibility—until now, that is. Scientists from Northwestern University’s Feinberg School of Medicine and McCormick School of Engineering have developed “bioprosthetic” ovary structures that allowed infertile mice to not only ovulate but also birth and nurse healthy offspring, according to a paper published this week in the journal Nature Communications . Composed of rapid-prototyped gelatin scaffolds, and primed with immature eggs, the bioprosthetic ovaries successfully boosted the hormone production necessary for restoring fertility in the mice, researchers said. “This research shows these bioprosthetic ovaries have long-term, durable function,” Teresa K. Woodruff, a reproductive scientist and director of the Women’s Health Research Institute at Feinberg, said in a statement. “Using bioengineering, instead of transplanting from a cadaver, to create organ structures that function and restore the health of that tissue for that person, is the holy grail of bioengineering for regenerative medicine.” Related: Organovo’s Bioprinter Technology Could Lead to 3D Printed Human Organs Woodruff and company plan to test the structures in pigs, with an eye toward human trials in the future. The technology could have significant implications for women with fertility issues, particularly cancer patients who often lose their ovarian function after intensive chemotherapy. “What happens with some of our cancer patients is that their ovaries don’t function at a high enough level and they need to use hormone replacement therapies in order to trigger puberty,” said Monica Laronda, co-author of the study and a former post-doctoral fellow in the Woodruff lab. “The purpose of this scaffold is to recapitulate how an ovary would function. We’re thinking big picture, meaning every stage of the girl’s life, so puberty through adulthood to a natural menopause.” + Northwestern University Photo by Duncan Hull

Extraordinary man builds 25 plastic bottle homes for refugees in Algeria

Comments Off on Extraordinary man builds 25 plastic bottle homes for refugees in Algeria

A Sahrawi refugee in Algeria is rebuilding lives – literally. Born and raised in the refugee camp in Awserd near Tindouf, 27-year-old Tateh Lehbib Breica is constructing disaster resistant homes using discarded plastic bottles – for himself and others. These recycled homes are specifically built to endure harsh desert conditions for an affordable price. It’s no easy feat to construct homes in a climate where temperatures can spike to around 113 degrees Fahrenheit. Sandstorms also prey on refugee shelters in five camps near Tindouf, Algeria, where people live after fleeing violence in the Western Sahara War over 40 years ago. But the area also faces destructive rainstorms – in 2015 heavy rains wrecked thousands of homes. Related: Mayor born in Syria converts abandoned Greek resort into a sanctuary for refugees Breica may have found a solution in old plastic bottles filled with sand. He has a master’s degree in energy efficiency after participating in a United Nations High Commissioner for Refugees (UNHCR) scholarship program. He’d intended to build a rooftop garden, growing seedlings in the bottles, but the circular shape of the energy efficient home he was building posed a challenge to that idea. He wondered what he could do with the bottles instead and recalled a documentary on building with plastic bottles he’d seen during his time at university. The plastic bottle homes can better withstand storms than adobe , mudbrick, or tent homes, and are water resistant. The homes have thick walls, and partnered with their circular shape, stand up better to sandstorms. Breica built the first bottle home for his grandmother, who was hurt while being carried to a community center to hunker down during a sandstorm. Working with UNHCR, Breica has built 25 homes so far. He’s earned the nickname Crazy with Bottles for his work. Although he’s won awards for his design, he said, “People still see me as the guy obsessed with recycling bottles and building unusual houses.” Via UNCHR Images © UNHCR/Russell Fraser

KAIST Develops a Metal-Graphene Composite Material Hundreds of Times Stronger Than Pure Metals

Comments Off on KAIST Develops a Metal-Graphene Composite Material Hundreds of Times Stronger Than Pure Metals

Graphene  © AlexanderAlUS/ CORE Materials Researchers from the Korea Advanced Institute of Science and Technology (KAIST) have developed a new metamaterial that is proven to be hundreds of times stronger than pure metals . To maximize the potential increase in strength provided by the use of graphene, the KAIST team created a multi-layered structure, alternating layers of graphene and metal—this composite  nanomaterial  consists of graphene inserted into copper and nickel. The resulting metal-graphene multilayer composite material is the first of its kind, and the team’s research was published in the science journal, Nature Communications  in July of 2013.

INFOGRAPHIC: Shingle Recycling – Turn Your Roof Into a Road!

Comments Off on INFOGRAPHIC: Shingle Recycling – Turn Your Roof Into a Road!

Shingle recycling is a huge opportunity that is evolving way to slowly. About 22 billion pounds of roofing waste is removed from U.S. homes each year, the majority of which is asphalt shingles. Almost all of this roofing waste ends up in landfills. While shingle recycling has become available in more and more locations over the last few years, the great majority of homeowners and roofers do not have access to a shingle recycling facility near their community. Shingle recycling is such a great opportunity because recycled shingles contain asphalt that can be used in paving asphalt roads. Hot mix asphalt (HMA) producers purchase the recycled shingles to enhance their paving mixtures and create better roads. Check out Hometown Roofing Contractors ‘  Shingle Recycling  infographic below to learn more about the size of the problem — and the size of the opportunity!
