Comments Off on Tardigrades will be the last surviving creatures on earth after the sun dies

In the event that Earth is struck by an asteroid , the sun goes supernova or the planet is soaked in gamma ray bursts in an extreme energetic explosion, the last surviving creatures won’t be cockroaches – they will be tardigrades. Oxford University researchers recently discovered this after exposing the microscopic water bears to the only astrophysical phenomena likely to eradicate life on Earth . Not only did the team learn that the tardigrade can endure temperature extremes of up to 150°C (302°F), they discovered that the eight-legged animals can resist radiation levels of 5000 to 6200 Gy (around the dose used in some forms of chemotherapy), making them the most indestructible creatures on this rock. Dr. Rafael Alves Batista, a researcher at the department of physics at Oxford University, told the Daily Mail that the goal was to “study what is necessary to kill all life, not just humans. Batista added that the scientists were pleasantly surprised to learn that the water bear is incredibly resilient to most threats. Co-author of the study, Dr. David Sloan, wrote: “To our surprise, we found that although nearby supernovae or large asteroid impacts would be catastrophic for people, tardigrades could be unaffected. Therefore it seems that life, once it gets going, is hard to wipe out entirely.” Related: Water bear brought back to life after being frozen for 30 years Unlike humans, the tardigrade is extremely durable. As previously mentioned, the animals are resistant to high levels of radiation and can endure astronomically high temperatures. Additionally, the water bears were once frozen for thirty years, thawed out and were found to still be alive . Said Batista, “Without our technology protecting us, humans are a very sensitive species. Life on this planet can continue long after humans are gone.” As a result of the findings, the researchers concluded that the water bears could live on Earth for at least ten billion years and would only be wiped out when the sun exploded. “Huge numbers of species, or even entire genera may become extinct, but life as a whole will go on,” said Sloan. Some are unsurprised by the water bear’s hardiness, considering Russia found the species clinging to the International Space Station — alive — even while exposed to the vacuum of space. Regardless, the finding is exciting for scientists who desire to find life on other planets. Said Batista, “Tardigrades are as close to indestructible as it gets on Earth, but it is possible that there are other resilient species examples elsewhere in the universe . If Tardigrades are Earth’s most resilient species, who knows what else is out there. There might exist other creatures similar to tardigrade in other places. We have to keep searching.” Sloan added, “Our work suggests that the search for life in such places is justified even if the planet doesn’t seem hospitable.” The study will be published soon in the journal Nature .

Comments Off on Water bear brought back to life after being frozen for 30 years

Much like the concept of Futurama, nature has produced a creature hardy enough to survive being completely frozen for decades. Japanese scientists successfully revived tiny tardigrades – or “water bears”, their common name due to the shape of their heads – after they had been frozen for 30 years . Known as some of the most resilient living things on the planet, the water bears even lived long enough to reproduce. Read the rest of Water bear brought back to life after being frozen for 30 years

Comments Off on Africa Renewable Energy Initiative works towards 10,000 MW of clean power by 2020

With the wind at their backs,  civic and private institutions around the world are taking steps to build a clean energy future. The Africa Renewable Energy Initiative is a collaborative project that aims to install 10,000 MW of clean power across the continent by 2020. For perspective, that is enough energy to power 2.4 million homes in the United States.  This project represents an ambitious and necessary goal for a continent in which the population will double to 2.5 billion people by 2050 and 600 million people still lack access to electricity.

Comments Off on Microscopic “water bears” led researchers to discover a new type of glass

Glass seems pretty perfect the way it is, but researchers are constantly looking for ways to make it better. University of Chicago researchers stumbled on a new type of glass while studying tiny, sturdy little creatures called water bears or tardigrades . The microscopic animals produce a strange protective glass coating unlike any researchers have seen before, and it may have human applications that lead to more efficient lighting and solar power technology.

Dutch architect envisions self-sufficient desert cities constructed from salt

Comments Off on Dutch architect envisions self-sufficient desert cities constructed from salt

A brilliant new building material designed by a recent architecture graduate of TU Delft could solve several pressing environmental challenges at once. Taking what he calls the ‘biomimetic’ approach, Eric Geboers relies on solar energy to separate the salt from water in seawater. The resulting salt is then mixed with a starch derived from algae in seawater to create bricks that have greater compressive strength than earth, and could be used to construct aesthetically-pleasing buildings in arid regions. The desalinated water, meanwhile, would be used to grow food. Read the rest of Dutch architect envisions self-sufficient desert cities constructed from salt

Comments Off on Sea Creatures and Dinosaurs Inspire a Virtually Indestructible Home in Berkeley, California

People who live in Berkeley, California are certainly used to seeing some strange things on the streets of their city. But those who live in the neighborhood near 2747 Matthews Street may point out a structure that’s a little odd to even the most weathered of residents. Nicknamed “The Fish House” by locals, the Tsui House built by architect Eugene Tsui is touted by its creator as the one of the world’s safest dwellings . The design is based upon a small and segmented water creature known as a tardigrade , and also features a few architectural elements inspired by dinosaur physiology.
