Endangered mussels reproduce for the first time in decades

Endangered mussels are reproducing again in the Cedar River in Minnesota for the first time in decades. The Department of Natural Resources has been making efforts to spur the reproduction of mucket and black sandshell mussels in the river. In the past three years, the department released thousands of sand shells and mucket mussels into the river in the hope that they will start reproducing in the waterway.

The Cedar River endured devastating human activities for the past few decades, driving away the once-thriving population of mussels. Excessive pollution and overharvesting have already depleted most of its shells and the mussels themselves. The efforts to repopulate the tiny animals are now paying off.

Among the important roles that mussels play in the river include water filtration of bacteria such as E. coli. They also sequester chemicals and poisons by depositing them into their shells. Their shells are one of the popular ways of removing chemicals from water since they are not eaten by any other species in the food chain.

“That’s what’s so unique about mussels,” said Madeline Pletta, DNR biologist. “If they die out, their shells are still there, maybe for 100 years. So we know exactly where they were. If a fish dies, how would you ever even know it was there?”

On top of overharvesting, mussels became endangered after growing cities dumped raw sewage into rivers. With dams being built, it also separate their populations.

With the help of the Soil and Water Conservation District, several large earthen berms to protect shorelines and store stormwater have been installed. The city of Austin also have ongoing plants to replace wastewater treatment plants to reduce phosphorous pollution. And now thousands of mussels are doing their magic filtering the water and holding it in place.

5 Benefits of Drip Irrigation Systems

If you want a stunning yard and a low water bill, a drip irrigation system could be for you. Image: Jacky Parker Photography/Getty Images If you live in one of the parts of the country that’s been struggling with drought (or you just don’t want to spend a fortune on your water bill), you’ve probably felt that you face a choice with your outdoor areas. You can either be water conscious or have a beautiful, lush yard, right? When you’ve opted for traditional irrigation systems like sprinkler heads, that’s often true. But, good news, that’s not your only option as far as types of irrigation systems go. If you want a beautiful yard without the high water usage — and resulting bill! — a drip irrigation system could be just what you need. What is a drip irrigation system? This way to water your plants uses dripped water. A drip irrigation system runs either a perforated hose or drip emitters (connected by a hose) under the soil throughout your planting bed.

New riverside development in China will be an urban renewal

Architects VenhoevenCS have won a major riverside redevelopment in Shenzhen, China . They hope to protect large areas of land from flooding while also creating a vibrant new urban identity for the Bao’an district. The Pailao River Blueway Project constitutes a new biodiverse landscape along the central Pailoa River, an area under rapid urban development where rainfall intensity is increasing. Architects are using this project to design with the water instead of against it. It includes elements such as ponds, green roofs, urban farming plots, wetlands and soft banks, contributing to a natural sponge effect to absorb excess water from the river . Related: 100-year-old railway yard turned into a green space VenhoevenCS also has their sights set on integrating urban regeneration in the area. They have planned cultural and social spaces, including pavilions and parks for cyclists and pedestrians. The design illustrates their nature-inclusive approach, reshaping how humans and the natu

Say hello to the new Toyota electric vehicle, the bZ4X

Toyota is trying to win the electric vehicle game with a stylish new SUV loaded with techy features. The all-electric bZ4X will be rolling onto the lots of U.S. auto dealers this spring. If the name doesn’t immediately strike you as catchy, it might help to understand that “bZ” stands for “beyond zero.” The bZ4X is the first of seven in Toyota’s new line of bZ vehicles. That’s seven out of 15 BEVs, to throw another acronym at you. BEVs are battery electric vehicles, as opposed to HEVs (hybrid electric vehicles) or PHEVs (plug-in hybrid electric vehicles). Related: Consider these factors before buying an electric vehicle All these Vs will help speed Toyota toward its goal of carbon neutrality by 2050. Already, Toyota has more than 20 million models on the world’s roads. The company has pledged to invest another $70+ billion in EVs over the next nine years. So, back to the bZ4X. According to Toyota, the new “BEV-dedicated platform, a first for Toyota, was developed with Subaru

NASA to test the world's first electric airplane

NASA has shared details of its new all-electric plane that is set to take off to the sky this fall. The plane is designed to run fully on electric batteries , departing from the tradition of fuel-powered planes. If all goes well, this will be the first step toward achieving a cleaner, cheaper, and quieter future for aviation. Known as the X-57, the plane is lightweight compared to traditional planes . Its weight helps it use less power over the same distance compared to its equal fuel-powered planes. Further, the plane produces less noise as compared to fuel-powered options. According to NASA, the plane is currently being prepared for initial tests, which will be conducted in the desert east of Los Angeles.

The main reason for this is to help in comparison of the two models of the design. The experts at NASA w

Biomimicry house hints at a solution to the climate crisis

Houses separate us from nature. At least, that’s the idea we’ve had until now. Architecture that uses biomimicry , permaculture and related practices to keep nature in our building spaces offers a green alternative. B+H Architects Director of Biomimicry Jamie Miller is an advocate of sustainable building practices like biomimicry to help with the climate crisis. Biomimicry creates an architectural option that keeps us connected to nature, without removing the biodiversity from the spaces where we live and work. Now the B+H Architects’ newest residential project shows us how a home can blend right into nature itself.

What are stellar earthquakes that make stars move?

What are stellar earthquakes that make stars move? The Gaia mission of the European Space Agency revealed the earthquakes that occur thousands of light years away. Argentine astronomers explain the scope of this space telescope and its discoveries. In 2013 the European Space Agency (ESA), launched a unique space mission: the Gaia space observatory, a spacecraft designed specifically for astrometry: the science that measures the positions, distances and motions of stars with a precision never seen before. Scientists say the mission aims to build the largest and most accurate 3D space catalog ever made of the observable universe, with a total of approximately two billion astronomical objects, mainly stars, but also planets, comets, asteroids and quasars, among other fascinating objects in the vastness of space. This week, ESA released a new update of data collected by Gaia in the last three years, after having observed 10 million stars and space objects, which led to the publication of s

Bananatex launches a sustainable material revolution at Milan Design Week

A party of three has collaborated to create a multi-purpose material sourced entirely from banana leaves. Swiss bag brand QWSTION, a yarn specialist from Taiwan, and a Taiwanese weaving partner spent four years developing the new material, which is being revealed at the 2019 Milan Design Week. The strong, flexible material, called Banantex, offers a new universal option in the search for sustainable materials . Beginning at the source, the banana leaves come from a natural ecosystem of sustainable forestry in the Philippines. The banana trees grow naturally without the use of pesticides or other chemicals. Plus, they do not require any additional water. The banana plants are a boon to an area previously eroded by palm plantations, bringing back vegetation and a livelihood for local farmers.
