Oldest largest historical site in the US is in Pennsylvania

America’s oldest known archaeological site is only 27 miles southwest of Pittsburgh. This conveniently located attraction is known as Meadowcroft Rockshelter and Historic Village.

Of course, oldest sites are debatable, and new dating techniques will continue to refine human understanding of our history. But it’s safe to say this rock shelter in Washington County, Pennsylvania is old. It may have been inhabited continuously between 16,000 and 19,000 years. This guesstimate hinges on one piece of bark, so stay tuned.

In 1955, a farmer named Albert Miller found the site on his family farm in Avella. One day, he looked down a groundhog hole and spotted what appeared to be a prehistoric tool. He kept his find on the down low for 18 years before connecting with archaeology professor Jim Adovasio.

Adovasio began working at the site in the mid-1970s. The Mercyhurst University archaeologist has likened Meadowcroft to a “a late-Pleistocene Holiday Inn.” People passing through the area found shelter to camp beneath the sturdy rock overhang. “It has never flooded, it’s high and dry, the overhang, prehistorically, was fairly large, and it’s well ventilated,” said Adovasio, as reported by the website Archaeology. Hmm. Sounds better than some modern hotel rooms.

Over the years, researchers have found endless treasures at Meadowcroft. These include 20,000 artifacts, 956,000 animal remains, 1.4 million plant remains, and even a species of elk that once hoofed it around southwestern Pennsylvania. Meadowcroft Rockshelter became a National Historic Landmark in 2005.

One of the things that is so exciting about this rock shelter is that its location near Philly makes it accessible to so many people on the east coast. It reminds us that archaeology isn’t just far away in some other state, country or culture. The mysteries of the past are underneath our feet all the time.

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.

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.

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.

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. Related: It looks like a shark fin and helps urban river flooding A house that disappears into the landscape “Imagine stepping inside a house that disappears into a forest all without ever leaving the city,” B+H said.

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.
