Can We Redesign The Modern City With Synthetic Biology? Could We Grow Our Houses Instead Of Building Them?

Posted by in categories: bioengineering, biotech/medical, food, habitats, sustainability

Imagine waking up every morning in a house that is just as alive as you are. With synthetic biology, your future home could be a living, breathing marvel of nature and biotechnology. Yes, it’s a bold ambition. But this kind of visionary thinking could be the key to achieving sustainability for modern cities.

Our current homes and cities are severely outdated. Dr. Rachel Armstrong, a synthetic biologist and experimental architect, says, “All our current buildings have something in common: they’re built using Victorian technologies.” Traditional design, manufacturing, and construction processes demand huge amounts of energy and resources, but the resulting buildings give nothing back. To make our future sustainable, we need dynamic structures that give as much as they take. We need to build with nature, not against it.

In nature, everything is connected. For the world’s tallest trees—the California redwoods— their lives depend on their connection to each other as well as on a host of symbiotic organisms. Winds and rain batter the California coast, so redwoods weave their roots together for stability, creating networks that can stretch hundreds of miles. The rains also leach nutrients from the soil. But fungi fill the shortage by breaking down dead organic matter into food for the living. A secondary network of mycelia—the root-like structures of the fungi—entwine with the tree roots to transport nutrients, water, and chemical communications throughout the forest. What if our future cities functioned like these symbiotic networks? What if our future homes were alive?

This Pet Feeder Uses Facial Recognition So the Right Pet Gets the Treats

Posted by in categories: food, mobile phones, robotics/AI

If you have more than one pet, then you know how chaotic feeding time can be. Italian company Volta is hoping to make the process just a little bit easier with its AI-driven pet feeder, Mookkie, which visually recognizes each individual cat or dog and places their prepared food at each pet’s disposal.

The Mookkie, winner of the Innovation Award in the Smart Home category at CES 2019, features a wide-angle camera that deploys logic similar to the “face-unlock” feature of smartphones.

World’s richest man cuts health benefits for 1,900 Whole Foods workers

Posted by in categories: food, health

Jeff Bezos, the world’s richest man, is cutting health benefits for part-time workers at Whole Foods. The move will leave 1,900 people without health insurance.

The cuts don’t affect full-time employees, but will hurt those who work around 20 hours a week.

“I am in shock,” said one employee, according to Salon. “I’ve worked here 15 years. This is why I keep the job — because of my benefits.”

Navigating Water Shortages with Decentralized Water Control System and Irrigation

Posted by in categories: bitcoin, food, information science

Rural communities are often built on agriculture and livestock. That means they’re also dependent upon a strong irrigation system – a potential weakness as the global water crisis grows. To more efficiently manage and coordinate the use of a scarce water supply in agricultural communities, a team from the Polytechnic University of Madrid proposed a blockchain-based automatic water control system.

“We investigated how blockchain technologies can be used to solve the problem of user competition for scarce resources in communities,” said Borja Bordel, the project’s lead investigator. “We particularize the problem to the irrigation communities, where independent users must trust a system that automates a fair and trustworthy distribution of the available water resources, according to an individual quota set by the community and the consumption forecasts of its users.”

Rules are paramount for the proposed system and must be established upfront by the community of users. In a prosumer environment, users establish regulations for their individual and community water quotas. Those regulations are then taken by a transformation engine and are built, compiled, and deployed. A simple infrastructure of common valves and pumps are complemented by interactive electronic devices and allow a SmartContract to oversee decision-making and control algorithms, as well as the state of the water sources.

The future of food: what we’ll eat in 2028

Posted by in categories: food, robotics/AI

We’ve all heard that the future menu may involve less meat and dairy. But don’t worry, we could have customised diets, outlandish vegetables, robot chefs and guilt-free gorging to look forward to instead. And we reckon that makes up for missing out on the odd sausage.

Researchers alter mouse gut microbiomes

Posted by in categories: biotech/medical, food, health, sustainability

Humans choose food based on the way it looks, smells, and tastes. But the microbes in our guts use a different classification system — one that is based on the molecular components that make up different fibers. In a study published September 19 in the journal Cell, investigators found particular components of dietary fiber that encourage growth and metabolic action of beneficial microbes in the mouse gut.

The research aims to develop ways to identify compounds that can enhance the representation of health-promoting members of the gut microbial community. The goal is to identify sustainable, affordable dietary fiber sources for incorporation into next-generation, more nutritious food products.

“Fiber is understood to be beneficial. But fiber is actually a very complicated mixture of many different components,” says senior author Jeffrey Gordon, a microbiologist at the Washington University School of Medicine in St. Louis. “Moreover, fibers from different plant sources that are processed in different ways during food manufacturing have different constituents. Unfortunately, we lack detailed knowledge of these differences and their biological significance. We do know that modern Western diets have low levels of fiber; this lack of fiber has been linked to loss of important members of the gut community and deleterious health effects.”

Grains in the rain: New study opens the door to flood resistant crops

Posted by in category: food

Of the major food crops, only rice is currently able to survive flooding. Thanks to new research, that could soon change—good news for a world in which rains are increasing in both frequency and intensity.

The research, newly published in Science, studied how other crops compare to when submerged in water. It found that the —a wild-growing tomato, a tomato used for farming and a plant similar to alfalfa—all share at least 68 families of genes in common that are activated in response to flooding.

Rice was domesticated from that grew in , where it adapted to endure monsoons and waterlogging. Some of the genes involved in that adaptation exist in the other plants but have not evolved to switch on when the roots are being flooded.

How to Feed a Mars Colony of 1 Million People

Posted by in categories: food, space travel, sustainability

What might it take to feed a million people on Mars? Lab-grown meat, tunnel-grown crops and cricket farms, a new study finds.

When it comes to plans for crewed missions to Mars, NASA typically assumes round trips with only brief stopovers on the Red Planet. However, commercial space companies have emerged with the goal of colonizing outer space, with SpaceX specifically aiming to develop a civilization on Mars.

The Heterogeneity of Senescent Cells

Posted by in categories: biotech/medical, food, life extension, neuroscience

Cellular senescence, discovered in 1961 by Leonard Hayflick and Paul Moorhead, is a state in which cells no longer perform their functions, instead emitting harmful chemicals that turn other cells senescent. Senescence is primarily caused by telomere shortening and DNA damage, and senescent cells are known to contribute to multiple diseases, such as Alzheimer’s, Parkinson’s, and dementia.

One method of removing senescent cells is caloric restriction, which is a temporary reduction of food calories. This has been shown to be one of the most effective methods to decrease and slow the onset of aging phenotypes [1].

This is related to autophagy, which is the cell’s natural method of breaking down parts of itself when it doesn’t have immediate access to food [2]. Autophagy has been shown to both promote and prevent senescence. It removes damaged macromolecules or organelles, such as mitochondria, which would otherwise cause cellular senescence. However, some of the processes that cause autophagy cause cellular senescence as well [3].
