Comments Off on Dutch scientists zero in on pothole cure

Potholes plague roads around the world. These pits are annoying for drivers, but even worse, those that haven’t been well maintained may cause as much as a third of all deaths on highways. So scientists in the Netherlands are investigating materials able to repair themselves, and have zeroed in on asphalt and concrete . Many roads are laid with asphalt. The material is porous, which is both a blessing and a curse: the pores absorb noise but also lead to cracks and potholes. Materials scientist Erik Schlangen , chair of Experimental MicroMechanics at Delft University of Technology , is working on self-healing asphalt. He mixed steel fibers with asphalt to make the material conductive, and then when a large induction machine is run over the asphalt, heat helps close any cracks. The Verge pointed out since the machine is necessary, the asphalt isn’t entirely self-healing, but it does allow for easier repairs. Related: INFOGRAPHIC: America’s Failing Infrastructure and the Need to Improve Self-healing asphalt is undergoing testing on 12 roads in the Netherlands; one has been open since 2010 and all are in excellent condition. Regular asphalt roads tend to stay in good condition for seven to 10 years, however, so Schlangen said in upcoming years the difference will be clearer. He said self-healing asphalt could be 25 percent more expensive than typical asphalt, but could last twice as long. One estimate put the Netherlands’ savings with the self-healing asphalt roads at 90 million Euros every single year. And asphalt isn’t the only material with which scientists are innovating. Schlangen’s team is also looking at adding bacteria to concrete to make it self-healing as well. Bacteria produce calcium carbonate to fill in cracks. Schlangen said these bacteria can live for over 200 years in nature, so they’ll last for the lifetime of concrete. They also don’t harm humans. The scientists have applied the material to some structures and are working to improve it. Via The Verge Images via Pixabay and Alan Stanton on Flickr

Giant sequoia skyscrapers designed to keep rotted trees standing

Comments Off on Giant sequoia skyscrapers designed to keep rotted trees standing

Modernization has harmed giant sequoias: not only have they been cut down in groves, but climate change has diminished their lifespan. Four designers in South Korea want to help preserve the trees’ legacy with a skyscraper called Tribute: The Monument of Giant , that could be tucked inside hollowed-out trunks, helping to keep trees with rotted heartwood from crashing down. The skyscraper would allow a visitor to feel small inside the vastness of a giant sequoia, while also offering education about the natural wonders. Ko Jinhyeuk, Cheong Changwon, Cho Kyuhyung, and Choi Sunwoong believe in the past, human desires and development clashed with the natural world. They said nature’s response is the natural disasters that wreak havoc throughout the world. They pointed to deforestation as both a cause of such disasters and “one of the worst crimes on nature .” Earning an honorable mention in the 2017 eVolo Skyscraper Competition , they offered up an answer. Their skyscraper is enveloped inside a dying tree in a bid to help keep it standing. Related: Incredible farming skyscraper could fight poverty and feed the world Although giant sequoias can be over 300 feet tall, with diameters between 20 and 26 feet, their roots often aren’t deep, so when their heartwood – what the designers described as a structural backbone – starts to rot, the weight of the trees can cause them to topple over. A skyscraper nestled inside could prevent this ending. “This project attempts to show a new architectural approach to human coexistence with nature,” the architects said in their design statement. They said their skyscraper, inside the empty void of a giant sequoia, wouldn’t hinder the breathtaking beauty of the tree. The building would then become “active as an artificial organ to replace the trunks rotten away.” Platforms inside the tree would offer opportunities for laboratories, exhibitions, education, and photo opportunities on observation decks. A lattice-like cage would comprise an outer casing that appears to blend in with the tree. Via eVolo and Dezeen Images via eVolo

Comments Off on Scientists make eco-friendly batteries out of leaves

When we gaze up at a tree full of lush, green leaves we are actually looking at hundreds of tiny batteries. These tiny appendages save energy for the tree to use at a later time, a natural process scientists have harnessed to create literal leaf batteries as eco-friendly alternatives to the lithium powerhouses of today.

New study shows global warming will happen even faster than we thought

Comments Off on New study shows global warming will happen even faster than we thought

A new study shows we are entering a vicious cycle of greenhouse gas emissions and global warming . As humans burn more fossil fuels and release more greenhouse gases, global temperatures rise. As temperatures rise, more natural greenhouse gases, from sources such as lakes, also rise, adding to the accumulation of heat-trapping gases in the atmosphere. The study, from Linköping University in Sweden, concludes this cycle will make global temperatures rise more quickly that scientists have predicted.

New study finally puts a number on the amount of water in the Earth’s crust and it’s huge

Comments Off on New study finally puts a number on the amount of water in the Earth’s crust and it’s huge

The adage “out of sight, out of mind” applies to a whole lot of things in this world, but we usually don’t think of water as being one of them. After all, some 70 percent of the Earth’s surface is covered in the wet stuff and it falls from the sky on a somewhat regular basis. However, scientists have known for decades that there is an enormous amount of water hidden under the planet’s crust as well. It’s been nearly 40 years since experts attempted to determine how much water that is, and a new study purports to do just that , with many more details and measurements than were available in the 1970s when the previous figures were calculated.

This new material could efficiently turn greenhouse gases into fuel

Comments Off on This new material could efficiently turn greenhouse gases into fuel

Many scientists have been eager to explore the concept of carbon capture  – and especially the concept of transforming greenhouse gases into methanol – for several years. It’s an encouraging concept for sucking carbon emissions out of the atmosphere, slowing global warming and creating handy biofuels in the process, but so far the technologies that would accomplish this transformation haven’t been particularly efficient. But new research by the Department of Energy’s Argonne National Laboratory  has developed a copper-based material that could make the process a realistic possibility.

The mysterious phenomenon of “hair ice” finally solved by scientists

Comments Off on The mysterious phenomenon of “hair ice” finally solved by scientists

For nearly a century, scientists have been baffled by the phenomenon known as hair ice – hair-like ice formations found in the forest during certain times of the year. Now, scientists have discovered that the answer to the mystery may be found in the humble fungus. Though most of us don’t realize it, fungi are pretty incredible organisms. The majority of carbon sequestration in northern forests is facilitated by fungi , clean-burning biofuel can be created by fungi, and fungi can be used to remove toxins such as BPA out of the environment.  Not impressed? Fungi also play an essential role in building the environment, as scientists recently determined after finding that the beautiful and rare “hair ice” are the handy work of fungi.

Click here to view the embedded video. A new report has revealed the underground workings of the Yellowstone National Park volcanic system – and in the process unveiled new details of how one of the world’s largest volcanoes could catastrophically erupt on a scale never-before seen by humanity. According to the Washington Post , an eruption in Yellowstone would eject 1,000 times as much material as Mt. St. Helens did in 1980, creating a disaster of global scale. Needless to say, scientists have been busy studying the inner workings of Yosemite’s volcanic system and a new study from the University of Utah now shows a complete diagram of Yellowstone’s system that reveals some stunning details that show how massive the eruption could actually be.
