BBC Earth – Arctic Siberia’s Nomadic Nenets herders have migrated with reindeer for generations. Reindeer were among the last animals domesticated by humans.
According to the Nenets legend, the humans promised the reindeer that they would protect them on their long migration from the mainland to the seashores as long as the reindeer provide humans with all their needs, including milk, fat, meat, bones, horns, and skins. The nomadic reindeer herders reside in the taiga forests of the Russian tundra and northern Mongolia.
Financial Times – One of world’s favorite drinks is under threat from global warming. The world’s top coffee producing nations all lie at similar tropical latitudes, where even small rises in temperature are forecast to have severe consequences for people and agriculture. But as the FT’s Nic Fildes reports, in Australia, scientists are tackling the problem by trying to develop a better, hardier coffee bean.
The system is based on simple flat pack modules made from recycled reinforced polymer. These are extremely strong and resilient and can be easily transported and assembled on location
The modules can be assembled in different configurations to provide floating foundations for floating infrastructure, public spaces or housing.
A growing acknowledgement of sea level rise and an increased risk of urban flooding has contributed to a sharp increase in interest in building on water, but current solutions, including polystyrene filled concrete foundations and plastic pontoons are inflexible, difficult to transport and highly unsustainable.
MAST has envisioned a new system of simple of flat-packed modules made from recycled reinforced plastic, that can be easily transported around the globe and assembled into countless configurations, providing a secure floating foundation. The system offers a sustainable and highly flexible solution for building almost anything on the water; from floating houses in Seattle, to floating campsites on Oslo fjord, to saunas on Hobart’s riverfront.
The system was inspired by gabion construction, an ancient technology which utilises mesh cages filled with rubble to create extremely sturdy, low cost foundations. In this case the concept is inverted; and the modular ‘cages’ are filled with locally sourced, up-cycled floatation supporting the weight of any structure built on top. they are also much more adaptable than existing solutions since floatation can be added or adjusted at any time if weight is added or shifted around above.
Land on water will provide a climate resilient and adaptable solution for the construction of new floating buildings worldwide but could also lead to an entirely new type of dynamic and organic off-grid floating community and an alternative to the large master-planned floating cities currently under development which repeat many of the mistakes made by urban planners in the middle of the 20th century.
Frozen Planet II (2022): This six-part series – narrated by Sir David Attenborough – explores the wildlife found in the world’s coldest regions: the Arctic and Antarctic, high mountains, frozen deserts, snowbound forests, and ice-cold oceans. From polar bears to penguins, and from snow monkeys to Siberian tigers, each species must overcome a unique set of challenges to endure its extreme environment.
Phoenix, Arizona is coming up with innovative ways to beat the heat.
Phoenix, the capital of Arizona, is accustomed to a hot desert climate, but day and night temperatures have been rising due to global heating and the city’s unchecked development, which has created a sprawling urban heat island.
Scorching temperatures have made summers increasingly perilous for the city’s 1.4 million people, with mortality and morbidity rates creeping up over the past two decades, but 2020 was a gamechanger when heat related deaths jumped by about 60%.
A previously unidentified population of polar bears documented on the southeast coast of Greenland uses glacier ice to survive despite limited access to sea ice.
At COP26 countries made a host of promises and commitments to tackle global warming. Now, a new analysis suggests these pledges could limit warming to below 2˚C — if countries stick to them.
03:48 Efficiency boost for energy storage solution
Storing excess energy is a key obstacle preventing wider adoption of renewable power. One potential solution has been to store this energy as heat before converting it back into electricity, but to date this process has been inefficient. Last week, a team reported the development of a new type of ‘photothermovoltaic’ that increases the efficiency of converting stored heat back into electricity, potentially making the process economically viable.
07:56 Leeches’ lunches help ecologists count wildlife
Blood ingested by leeches may be a way to track wildlife, suggests new research. Using DNA from the blood, researchers were able to detect 86 different species in China’s Ailaoshan Nature Reserve. Their results also suggest that biodiversity was highest in the high-altitude interior of the reserve, suggesting that human activity had pushed wildlife away from other areas.
11:05 How communication evolved in underground cave fish
Research has revealed that Mexican tetra fish are very chatty, and capable of making six distinct sounds. They also showed that fish populations living in underground caves in north-eastern Mexico have distinct accents.
14:36 Declassified data hints at interstellar meteorite strike
In 2014 a meteorite hit the Earth’s atmosphere that may have come from far outside the solar system, making it the first interstellar object to be detected. However, as some of the data needed to confirm this was classified by the US Government, the study wasn never published. Now the United States Space Command have confirmed the researchers’ findings, although the work has yet to be peer reviewed.
