Resilient floating school provides reliable education in flood-prone African village

Resilient floating school provides reliable education in flood-prone African village | De Natura Rerum | Scoop.it

Built with recycled and local materials, this floating school is a prototype that could be built in other flood-prone areas.

Designed by NLÉ, a firm founded by Nigerian-born architect Kunlé Adeyemi, the Makoko Floating School is a prototype that could be applied to other areas in Africa that face infrastructural and social challenges due to climate change.

Christian Allié's insight:

........"""""""""""""""""........

 

..  [Makoko Floating School] is a movable 'building' or 'watercraft' currently located in the aquatic community of Makoko in the lagoon heart of Africa's second most populous city - Lagos, Nigeria. It is a floating structure that adapts to the tidal changes and varying water levels, making it invulnerable to flooding and storm surges. It is designed to use renewable energy, to recycle organic waste and to harvest rainwater.

[ ... ]

....... 

The designers envision whole communities built in this clever fashion, which can float with on the rising waters of a natural disaster. Check out our other post on flood-resistant, floating bamboo homes, and see more over at Dezeen and NLÉ.

CORRECTION: The floating platform is made of "16 wooden modules, each containing 16 [recycled empty plastic barrels]." We apologize for the error.

Seth Dixon's curator insight, January 6, 8:30 AM

This last summer, my family went to five national parks on our cross-country journeys.  I love exploring the wonders and beauties in our National Parks, so this man's 2016 voyage to see all 59 National Parks makes me incredibly jealous.  My grandparents took me to Yellowstone and Yosemite when I was young.  These trips inspired in me a deep awe for the wonders of this Earth.  So go discover someplace new to you this year.

La mystérieuse chaleur du palmier à ivoire

La mystérieuse chaleur du palmier à ivoire | De Natura Rerum | Scoop.it

"Une équipe de scientifiques équatoriens et français lève un pan du voile sur les mécanismes de production de chaleur des bourgeons du palmier à ivoire. Cette thermogénèse pourrait être expliquée par son lien avec la pollinisation."

 

Institut de recherche pour le développement (IRD), 21.12.2016

 

"Le palmier à ivoire, communément appelé tagua, est une espèce endémique de la région côtière de l’Equateur. Les agriculteurs qui exploitent cette ressource - premier produit d’exportation du pays au 19ème siècle - ont remarqué depuis longtemps qu’une partie de sa fleur générait de la chaleur. "Les paysans la sentent dans leurs mains mais ils ignorent comment elle est produite, raconte le biologiste Rommel Montùfar de l’université PUCE de Quito.La littérature scientifique évoque également cette particularité mais sans donner plus de détails."

 

Cette capacité à produire de la chaleur, appelée la thermogénèse, est rare chez les plantes. Elle a été étudiée en Europe et en Amérique du Nord chez les fleurs de l’arum dont une large membrane blanche ou colorée enveloppe une longue inflorescence. Les fleurs mâles puis femelles chauffent consécutivement afin d’attirer les insectes pollinisateurs.

 

Le palmier ivoire génère quant à lui de la chaleur avant la floraison ! Une particularité dont les scientifiques viennent de rendre compte dans une récente publication."

Eye of the Storm 4K Ultra HD

Eye of the Storm is a winter saga in Iceland. In Iceland there are many kinds of storms. Ice, snow, rain, sand, ash, solar, magnetic, and more.

Storms are agents of change. While often destructive and unpredictable, they also demonstrate the unyielding power of nature. They reveal nature's beauty and its hand in creating the landscapes we see today.

Shot in Iceland between February and March, 2014, I was lucky enough to witness and film the power of an X-class solar flare and coronal mass ejection hitting our atmosphere. The resulting auroras were a sight hard to believe, even in person and seeing it with my very own eyes. Enjoy the film!

L'équipe de recherche a commencé par déterminer les effets de ces extraits de plantes sur la levure de bière modèle de « touffes » de protéine bêta-amyloïde, une caractéristique majeure de la maladie d'Alzheimer. Après l'exposition à certains de ces composés chimiques, la santé de la levure s'est améliorée de façon spectaculaire, ce qui a encouragé les chercheurs à évaluer les effets de ces mêmes molécules sur des mouches des fruits génétiquement modifiées pour développer les symptômes de la maladie d'Alzheimer. Un traitement régulier avec des extraits d'algues permet de prolonger la durée médiane de vie des mouches de 2 jours. Avec un extrait de figue de Barbarie, leur durée de vie est prolongée de 4 jours.

Are tiny grazers the new hope for Caribbean reefs?

Are tiny grazers the new hope for Caribbean reefs? | De Natura Rerum | Scoop.it
Thirty years ago a mysterious disease wiped out long-spined black sea urchins across the Caribbean, leading to massive algal overgrowth that smothered already overfished coral reefs. Now, marine biologists at the Smithsonian Tropical Research Institute (STRI) report that smaller sea urchins and parrotfish may be taking the place of the large sea urchins, restoring the balance on degraded reefs.

As a STRI short-term fellow, Catie Kuempel joined staff scientist Andrew Altieri to explore a large area of the sea floor in Bocas del Toro, Panama, where corals had died but, surprisingly, algae had not taken over. The most common algal grazers they found were a small sea urchin about the size of a ping pong ball, Echinometra viridis, and a tiny finger-sized striped parrot fish, Scarus iseri, which would be of no interest to fishermen. They propose that these tiny organisms may be able to preempt shifts from coral to algae on degraded coral reefs. They may be small, but there are a lot of them: small grazers comprise up to 95 percent of the biomass of all grazing organisms on the reefs in the study. Their combined weight is roughly equal to that of a smaller number of bigger herbivores on healthier reefs.

Scientist Resurrects Ancient Creatures by 3D-Printing Them in Metal

Scientist Resurrects Ancient Creatures by 3D-Printing Them in Metal | De Natura Rerum | Scoop.it

Over the past few years, we’ve seen 3D printing prove itself an invaluable resource for engineers. It’s helped us build prosthetics, instruments, drones and a mini jet engine that can blast at 33,000 RPM. But in the hands of creatives, the hackable tech has done something else entirely: allowed them to make unbelievable art. For University of Chicago assistant professor Dr. Allan Drummond, that art comes in the form of resurrecting ancient beasts.

 

A biochemistry and human genetics researcher, Drummond studies everything from how cells adapt, to the multi-million-year evolution of the species we share our planet with. It’s no surprise then, that he took a particular interest in trilobites. The extinct arthropods cruised the world’s oceans for some 270 million years – with over 17,000 known species, they are the most diverse group of animals preserved in the fossil record.

“We find their shells fossilized everywhere,” explains Drummond. “They’re museum staples – but we rarely see what they really looked like, with all of their soft tissues (legs, antennae, gills) intact.”

 

Determined to print a trilobite in all its glory, Drummond turned to the literature and online forums for guidance. “The first step was to look at as many trilobites as possible and choose one,” he recalls. “I’ve always loved these fossils, but the moment they turned from fossils, into living organisms for me, was when I saw the new generation of preparations displayed at Chicago’s Field Museum. I couldn’t believe what I was seeing. In my mind, trilobites were flat, if beautiful, primitive creatures. Seeing those preparations made it clear how not-flat and not-primitive they were.”

 

In order to narrow down the options, Drummond eliminated any trilobite groups with delicate spines – which many of them had – that would easily break, as well as any that were too simple to print with extensive detail. He settled on Ceraurus, a genus that roamed the Earth in the middle to upper Ordovician, 470-445 million years ago.

 

“Ceraurus is ideal,” he says. “They have long yet substantial genal [head segement] and pygidial [tail segment] spines, complex thoracic armor, gorgeous curves, unmistakable trilobite form. Enough detail to warrant 3D printing, enough structural solidity to survive it.”

Mosses and algae are known to grow at altitudes this high, but this was something different: a vascular plant; a cushion plant, to be exact. In fact, there were six different species of them, all clinging to a small, gravelly, southwest-facing patch of land on Mount Shukule II, in the Ladakh region of India. The tiny community of vegetation now represents the highest plants ever discovered, surviving at an altitude over 20,175 feet, reports New Scientist. [...]
