No More Fertilizer! eSoil Unleashes 50% Growth Surge in Plants

No more fertilizer! eSoil unleashes 50% growth surge in plants.

eSoil

We may have figured out what grew Jacks beanstalk so big.

Scientists at the Linköping University in Sweden have recently discovered that electricity can stimulate crop production by a whopping 50%!

They have invented what they call electronic soil, or eSoil. This soil is an electric elixir! It is not really “soil”, it is more like a process that stimulates seedlings. These seedlings then grow up to be massive in comparison to plants grown conventionally.

Here’s everything you need to know.

What is eSoil?

eSoil is a bioelectronic process that uses electric fields to stimulate plant growth. It is used in hydroponic farming, a method of farming that uses water to deliver nutrients to plants instead of soil. Research has shown that using eSoil for hydroponics increases the width, length, and even the roots of plants. This results in a dry weight increase of up to 50% within 15 days. Scientists plan on researching the process further, and they are hopeful that it can become a large part of hydroponic farming in the future.

What is Hydroponic Farming?

Hydroponics farming is a method that is used to grow plants without using soil. The plants grow in dense indoor spaces, making it easy for farmers to monitor and control. Hydroponics requires a lot of monitoring. Plants need 17 essential nutrients for them to be functional. If any one of these nutrients is missing, then plant growth suffers.

How do Hydroponic Plants Get Nutrients?

Plants get carbon and oxygen from air, and hydrogen from water. The 14 other nutrients needed for plants come from soil. Hydroponic plants are not grown in soil, so there needs to be an alternative method to deliver nutrients to the plant. With hydroponic farming, nutrients are mixed with slightly acidic water. This water then delivers nutrients to the roots of plants.

How Nutritious are Hydroponic Plants?

The nutritional profile of food grown using hydroponic systems is very similar to soil-based farming and may even be better. Research comparing soil and hydroponic systems show that some hydroponic grown plants have higher levels of lycopene and Beta-Carotene. Lycopene is an antioxidant that gives fruits and vegetables their red and pink color. Beta-Carotene is related to Lycopene, and is a converted into vitamin A by the body.

How Does eSoil Work?

In the scientific article published on PNAS, electrically stimulating the roots of plants using eSoil led to progressive signs of growth. Scientists guess that this is because the positive effect of stimulation causes roots to take up nutrients more efficiently. Interestingly enough, increased growth did not happen right after stimulation, but between 10 and 15 days after.

Why is eSoil Important?

Hydroponics replaces the use of chemical fertilizers. Chemical fertilizers release GHGs (greenhouse gasses) into the air. Nearly 18,000 deaths happen every year from agriculture pollution in the U.S. alone. Since eSoil is part of a hydroponic farming system, no fertilizer is required because hydroponics does not require soil.

Moreover, one of the GHGs released by fertilizers is nitrous oxide, or “laughing gas”. This gas is bad for the environment and could pose risks to human health. Plants grown with eSoil have been shown to be more efficient at nitrogen assimilation. This is a process where plant roots use nitrogen to create amino acids so that they can grow. This is call for good news because nitrous oxide is partly composed of nitrogen.

What is the Future of eSoil?

It is unknown whether eSoil effects the plant itself, or the environment of the plant. Moreover, the study done at Linköping University only stimulated seedlings with electricity, not plants that had already grown roots. Now that there is proof that electric fields can stimulate bigger plants, electronic soil will likely have a future that involves more use and study.

what is the future of electronic soil, or eSoil?

IC INSPIRATION

The entire universe is energy.

Electricity is the movement of electrons between matter.

Right now, if you put you’re feet in bare soil, you will have electrons coursing from the earth and into your body. This is known as earthing, and it has actually been shown to reduce inflammation and increase sleep quality.

We were intelligent enough to figure out how to charge up electrons into creating electricity; and now, electricity is being used to charge up plants to grow larger than ever before.

When I read this study, I couldn’t help but think about Jack and the Beanstalk. Maybe those beans weren’t magic at all. Maybe they were just around the right sort of energy. After all, if I took the tiniest electrical device and showed it to dear old Jack, he would probably think it was magic too.

The right energy can do all sorts of things. That’s what I like to bring to inspiringclick! If you want to be surrounded by that sort of energy wherever you go, follow below!

First Human Sentinel Underwater Habitat to debut in 2027

Published

The DEEP Sentinel Systems creates humanity's first underwater habitat

Sentinel Underwater Habitat

Our planet is covered in a deep, beautiful ocean that we know very little about. More than 80% of this great expanse has never been explored or mapped. There are underwater worlds that no human being has ever seen before.

We have a better understanding of the surface of the Moon and Mars than we do of most of our oceans. Yet, the ocean is so central to our very existence.

How can so much of our own planet be such a mystery to us?

Who is Pioneering Humanity’s First Underwater Habitat?

Engineering wonder, DEEP, is an organization that is currently creating the first human underwater habitat. Their goal is to make humanity aquatic. They say it best on their website:

Imagine if the only way we could explore the rainforest was to fly over it with a helicopter. We could only study the forest floor for a few minutes before having to leave to refuel and resupply. Think of how much we’d be missing.

Well, that’s how much we’re missing by not creating a human habitat underwater.

There has been limitations of undersea exploration for generations. The incompatibility of the human body with the demands of the deep has kept much of the underwater world out of our reach. We’ve long been limited to quick glances from above, always cut short by the need to surface.

However, those barriers are about to be ripped down with the introduction DEEP’s underwater Sentinel System™.

What is the Deep Sentinel System?

DEEP’s Sentinel System aims to create a new deep-water habitat and laboratory. These systems are capable of supporting human life for extended periods. It will allow researchers to live and work at depths of up to 200 feet for as many as 28 consecutive days. DEEP expects it to be fully functional by 2027.

Developing this facility has taken a great deal of careful planning and testing. It’s made out of highly researched and tested materials for optimal safety. This will allow it to endure in the high-pressure environment of the seafloor.

As well, it allows the station to maintain a consistent interior pressure to protect the health of the workers. The pressure can be adjusted for wherever and for how long the station is to stay underwater.

More than that, the station is built to be convertible. That means like a child’s building toy, new pieces and sections can be added or removed easily. There’s no need to disturb the existing facility. A station for a two-person team can instantly become a research facility for six scientists just by adding a few rooms.

What are the Benefits of the Sentinel Underwater Habitat?

DEEP Sentinel is pioneering humanity’s first underwater habitat. Living underwater for extended periods can help us better understand the ocean in ways we cannot currently imagine. There will be plenty of benefits of this sentinel underwater habitat:

  • Climate Change Management: The Sentinel System will allow scientists to study the impacts climate change is having on our oceans. This can be particularly helpful in knowing whether submerging sargassum seaweed to ocean floor is a good idea or not.
  • Renewable Energy Source: DEEP’s underwater habitat project can help us better understand ways in which the ocean can provide an effective renewable energy source. There is a lot of potential in using wave power in helping curb the harmful emissions of fossil fuels.
  • Human Impact: Perhaps most importantly, it could allow us to understand our own impact on the oceans of our world. We may see exactly what impact our industries and activities have on marine ecosystems and from where, and to what extent.

However, living in confined quarters far below the surface of the water will definitely have its challenges. A big part of the ongoing research has surrounded the question of whether humans can really live in the briny deep.

What Will the Underwater Sentinel System be Like?

Humans need sunlight, fresh air, privacy, and freedom. All of these things can be a challenge 200 feet beneath the surface of the water. So, underwater habitat projects like the DEEP Sentinel are designed to rectify that.

The Sentinel System provides living quarters whose pictures seem to rival some very fine homes on dry land.

what will the sentinel underwater habitat be like

Each occupant is provided with a private bedroom that comes with a bed big enough to easily fit a six-foot person, cupboards for storage, and a small worktable.

The Sentinel System also benefits from a large, overhead viewport, or window, through which the occupant can watch the ocean drift by, while providing a feeling of spaciousness.

There are also fully equipped bathrooms, laundry facilities, and a dining and kitchen area.

All this is in addition to the Mezzanine Deck, an area of the underwater habitat dedicated to the work of the crew. This space is designed to be completely modified to meet the needs of any given project. This ensures the lab will always be tailor-made to whatever work is being done during a particular mission.

The facility will include a large bioreactor to deal with the inevitable waste that comes with human biology.

Companies like Oneka Technologies are developing ways to desalinate seawater and make it drinkable. Could this process potentially supply a station like this with unlimited drinking water in the future?

One thing is certain, there is no stopping human ingenuity!

When Will Humans be Able to Live Underwater?

DEEP’s Sentinel System is due to be opened in 2027. The first station will open in the UK’s Southwest and Wales where the organization is based out of. The research team expects their underwater habitat project to establish a permanent human presence in the ocean.

In fact, the Sentinel System expects to have as many as ten stations operating all around the world by 2035, according to Oceonographic. They’ve even gone so far as to predict the first human undersea birth by 2050.

Time will tell, but it can’t be denied that this opens up amazing new doors.

In the best case scenario, the knowledge that comes from this engineering will help us discover a variety of new species, as well as bring about a clean energy future for 2027 and beyond.

The work of big research labs like DEEP is incredible.

If inspiring click has taught us anything, its that the strength and passion to fix our mistakes also lies in the hearts of the young.

Finlay Pringle. Remember that name. You’re going to keep hearing it.

Finlay is a 16-year-old boy from the town of Ullapool in Scotland. This little village is on the north coast. It sits on the shores of Loch Broom, an inlet that opens into the Atlantic Ocean. This lifelong and immediate exposure to the sea has impacted Finlay in wonderful ways and has shaped the work he’s doing today in combating ocean pollution.

He’s a young boy with a mission. He’s determined to save the world’s oceans and wetlands. Particularly, he has a strong interest in sharks.

He explained to the North Sutherland Wildlife Group, “… we as a species kill 100 million sharks every year. That equates to 3 every second… By the time you have read this blog another 1000 sharks will have been killed.”

Shark species as a whole are in serious danger of disappearing from our oceans in the very near future. In the last 50 years, global shark populations have dropped by 71%. If this doesn’t change, sharks could go extinct as early as 2050.

The declining numbers have already caused serious changes to the marine ecosystem. This includes the health of small fish and other sea life which is a food source for the sharks. The lack of sharks to balance the population of these species could lead to an overabundance of certain algae and bacteria. When that happens, large portions of the seafloor are left barren and unlivable.

Finlay is determined not to let that happen. Known as the Ullapool Shark Ambassador, he’s been hard at work protecting the ocean since he was 10 years old. He’s the first student in Scotland to start a climate strike to bring attention to climate change and the problems it brings.

He’s become a popular speaker at various conferences and gatherings where people meet to discuss the problems of the environment.

That inspirational vision is within our reach. As long as we have kids like Finlay out fighting for the earth, we can’t miss.

Hemoglobin Battery Gives 30 days of Sustainable Power by Using a Protein Found in Blood Cells

Published

on

Hemoglobin battery offers up to 30 days of sustainable energy.

The Demand for Batteries is Increasing

The everyday battery is a staple of portable electricity generation.

In this world of energy-demanding devices, it’s estimated that the battery industry makes $50 billion each year. Electric cars, cell phones, and even smart canes for the visually impaired all require battery power to function. This number is only expected to go up in the next decade as more devices are produced.

It’s no wonder, then, that the race for a better battery is on. The ideal battery would have a long life, be adaptable to unusual conditions, and have a minimum negative impact on the environment.

But the good news is that batteries have recently gotten a lot better.

Hemoglobin Battery

A research team in the University of Cordoba in Spain has created a hemoglobin battery that operates using the protein hemoglobin. Hemoglobin is a protein found in red blood cells that delivers oxygen to our blood. It transports oxygen from the lungs to the organs, then carries carbon dioxide back to the lungs to be exhaled out of the body. The Hemoglobin batter uses hemoglobin as the electrolyte in a zinc-air battery.

Hemoglobin Batteries vs Lithium-ion Batteries

The most common batteries on the market today are lithium-ion batteries. These are the ones we buy in stores and put in most devices. Today, lithium-ion battery are a major problem for the environment. Lithium mining is in high demand, but lithium is becoming scarce. Groundwater and soil are becoming contaminated by the millions of batteries that end up in landfills every year. Due to their biocompatible nature, Hemoglobin batteries could reduce this in the future.

Hemoglobin Batteries vs Zinc-Air Batteries

Zinc-air batteries are commonly used in things such as watches and medical equipment. It works in a similar process to other batteries; However, it uses zinc and a supply of oxygen to produce power as opposed to lithium like other batteries. While this makes it more sustainable than other batteries, the hemoglobin battery is stronger, lasts longer, and more biocompatible.

The Benefits of the Hemoglobin Battery

  • Longevity: The team at the University of Cordoba reports that they have been able to operate the hemoglobin battery on only 0.165 milligrams of hemoglobin for up to 30 days. This could be promising. The fewer battery changes that are needed, the more cost-effective batteries become.
  • Biocompatibility: This battery holds much promise for use in technology that must be embedded in the body, such as a pacemaker. Since hemoglobin exists naturally in the body, it may be safer to use than a battery full of chemicals.
  • Strength: Hemoglobin batteries can withstand conditions other batteries can’t. Other models can be damaged by humidity or need to be manufactured in special environments.

How Do Conventional Batteries Work?

Batteries operate on a system which is simple, yet ingenious.

A battery is a small, portable device that produces in itself. It allows a device to be operated without needing to be plugged into a wall outlet. This is essential for things like medical wearables, smart devices, and now, flying cars.

Electricity is a form of energy caused by charged atomic particles, such as electrons. When it sits still, it’s called static. When it flows from place to place, it’s known as a current. A battery has a process for creating this current and using it to power whatever device it’s plugged into.

Battery Pollution is a Big Problem

Battery pollution is a far bigger problem than most of us realize. North Americans throw away about 3.3 billion batteries every year. Less than five percent of the batteries consumed get recycled properly.

Batteries that get thrown into landfills leak harmful chemicals into the environment. This includes materials like lead, mercury, and cadmium. All of these are destructive to the environment and hazardous to humans and animals.

Hemoglobin Batteries in the Future

A sustainable battery is critical in a world of technological devices. The hemoglobin battery opens up a brand-new door toward meeting that need.

While the bio-based battery is promising, it still needs work. Scientists are currently looking for a biological protein that can make hemoglobin batteries rechargeable. Moreover, the battery needs a high amount of oxygen to function properly. This makes it an unlikely candidate for such things as space exploration and deep-sea studies.

However, every journey begins with a single step. The hemoglobin battery is a promising first step toward the future.

Another solution to the battery pollution problem may be brewing in a little garage in Minnesota.

Gabriel Riegert, a marketing student at St. Thomas University in Minnesota, decided it was time to find that solution. So, he and his roommate, Georges Macheta, opened a business called Converteca and got to work finding the answer.

They’ve developed a five-step process that not only recycles the battery but reclaims the material inside to be reused in new batteries.

  • They begin by deconstructing the battery and draining out any leftover energy using a diffusion tank.
  • They then separate the battery’s components, and wind up with a black, powdery mass that can be used to create materials such as lithium and nickel in new batteries.
  • Each material undergoes a purity check, then it’s sent to a battery manufacturing company.

This not only keeps the toxins out of the environment, but it also tackles another problem: lithium mining.

Most of the batteries we use in our cell phones, laptops, and other mobile devices are powered by lithium. This is a naturally existing substance that is extracted from the Earth through mining. But mining lithium is not an easy thing to do.

The process involves pumping tremendous amounts of fresh water into the shale in the mine. This is a problem because most mines are done in areas that are impacted by drought. These places also happen to be in short supply of fresh water.

From the murky slew that this creates, the miners extract a muddy slurry. This is left to evaporate. What’s left is huge pools of toxic waste that will sit for centuries.

A process to reclaim the lithium from those billions of cast-off batteries would reduce the need for mining and the impact it would have on our environment.

The Converteca process stands out because it has a 98.3% reclamation rate. Meaning that, 98.3% of the time, reused batteries in the Converteca process wont end up in the environment.

Converteca is gaining attention. In April of 2023, they won the $10,000 first prize in the Pitch Slam! at the e-Fest Undergraduate Entrepreneurship Competition.

It seems that young entrepreneurs are everywhere!

As long as inspirational people like Gabriel and Georges are unwilling to give up on finding solutions to problems, we can look forward to the day when our rivers and oceans will be, once again, free of battery waste.

How Long do Tortoises Live and Why are They so Important?

Published

how long do tortoises live and why are they so important?

Tortoises are Important to Ecosystems

There was a great deal of celebration when Jonathan the Seychelles Giant Tortoise turned 190 years old in 2022.

Although his exact date of hatching isn’t known, he was fully mature when he was taken from his home on the Seychelles Islands on the East coast of Africa. A Giant Seychelles reaches adulthood at about 50 years of age. That would place his hatching date sometime in the 1830s.

However, some of his caregivers believe that he’s actually much older than that.

Jonathan is celebrated for being the world’s oldest-known tortoise, but he’s not alone. Tortoises all over the world are known for their long stay on this Earth. This is more important than we may ever fully know because tortoises are one of the few animals on earth that have the power to create, change, protect, and even destroy a habitat. 

That’s a big thing for such a slow creature, and it’s the reason why Galapagos tortoise projects are very a very big deal to tortoise protection projects are very big in Galapagos islands. It turns out that keeping this amazing species alive for hundreds of years could have some profound benefits to ecosystems. 

How Long do Tortoises Live?

It can be difficult to tell the age of tortoises because these creatures routinely outlive most human beings. Moreover, hatching dates for wild tortoises are rarely known. Scientists place the average lifespan of a tortoise at anywhere between 80 and 150 years. Some are even thought to be as much as 250 years old.

Although these are all estimates, they are far from wild guesses. Tortoises provide several different clues about how long they’ve been around.

How to Tell a Tortoises Age

It is much easier to track the age of a captive tortoises because their conditions can be monitored and scientists generally have a lot of information to go on. This was the case with Jonathan the Seychelles giant tortoise.

When tortoises are not monitored, other methods are required to help scientists determine the age of a tortoise.

  • The Shell: Scientists can study a tortoise’s shell for clues. Older individuals will have smoother, less detailed shells than younger tortoises. This is because they’ve experienced decades of weather and wear-and-tear. However, this may not be so in tortoises who have lived in the shelter of captivity.
  • Behaviour: Like most creatures, older tortoises will be less energetic than they were when they were young. Scientists can watch a tortoise to see how much time it spends resting. The more rest periods a tortoise takes, the older it likely is (looks like we might have more in common with tortoises that we originally thought).
  • Tagging: Scientists have also made a study of the aging process of the tortoise. Scientists catch wild tortoises at less than two years old. They release it back into the wild with a mark on its shell so they can recognize it later. When they catch it again, they can make observations and notes about how it’s changed as it’s aged. This data can be used to estimate the growth of other individuals.
  • Fungal Growth: Wild tortoises often have fungal growth on their shells. How much fungus is present and what kind can provide clues as to how long a tortoise has been around. This method is most accurate when used along with other age-determining methods.
  • Bones: Scientists can study the layers of growth in a tortoise’s bones for a pretty accurate age estimate. Of course, this study can only be done on deceased tortoises since it requires dissection of the animal to retrieve the bones.

All of these methods help scientists tell the age of tortoises. Perhaps the more important questions, however, are what allows them to live that long.

Why Do Tortoises Live So Long?

Researchers have developed several theories as to why tortoises live so long and age so slowly. This includes genetic variances, the metabolism of tortoises, it’s shell, as well as its environment.

  • Genetic Variances: Scientists have discovered a genetic variance in tortoises. This difference provides an enhanced immune system. It also provides them with the amazing ability to suppress cancer. This genetic difference simply makes it less likely that a tortoise will die of illness.
  • Continued Growth: Tortoises never stop growing through their lives. Research finds that species that continue to grow tend to be around longer on average than those that don’t. This is because of the cell renewal and regeneration which continues as long as growth is happening.
  • Metabolism: The slower metabolism of a tortoise allows them to burn energy at a slower rate. They breathe more slowly and their heart rate is lower than many other animals. This allows their inner organs to work more slowly, and last longer.
  • Shell: Scientists have observed that animals with shells will often tend to live longer. This hard armour protects them from predators. Since they don’t have to work at protecting themselves, they have more energy to devote to living longer.
  • Environment: Studies have shown that turtles in captivity do not experience a higher mortality as they age, as those living in the wild do. In captivity, they don’t have to spend energy in foraging for food or water. That leaves more energy for replenishing their cells.

Whatever causes their long lives, it’s allowed them to stay around long enough to be one of the most important species on earth.

why do tortoises live so long

Why are Tortoises Important?

Tortoises are all around us. They exist on every continent except Australia and the Antarctic. It’s not surprising, then, that they’ve made their way into the hearts of so many cultures around the world.

The most famous instance of this, of course, is Aesop’s ancient Greek fable of the Tortoise and the Hare.

The tortoise has appeared in cave drawings, ancient literature, and in legends and creation stories all around the world. India, China, and Indigenous North America all have myths depicting the tortoise helping to build the world or holding it up on its back. The tortoise is also featured in the ancient stories of Greece, ancient Egypt, and Polynesia.

However, their most important place in the modern world is in their role as a keystone species.

Tortoises are a Keystone Species

The Galapagos Tortoise has been identified as a keystone species. This is any species that has a significant impact on its environment. When a keystone species is removed, the environment is altered substantially.

Specifically, the Galapagos Tortoise is known as an ecosystem engineer. Ecosystem engineers are animals that create, change, or protect a habitat. Tortoises make their habitat livable for other creatures, so its absence can even destroy a habitat.

Tortoises disperse and germinate seeds while grazing on plants. They trample down vegetation, opening up new spaces for fresh plants to grow using these seeds.

Tortoises are Endangered

Isla Santa Fe, one of the Islands in the Galapagos, was stripped of its population of native tortoises in the mid-1800s. Between their loss and the introduction of feral goats, the island suffered severe damage to both plants and soil.

The goats were removed by the 1970’s. However, the island ecosystem was unable to recover until a new population of tortoises from another island was released in Isla Santa Fe. Both local plant and animal life began to thrive again.

It’s through events like this that we can see how important the tortoise truly is to our world. This is also why it’s so important that every effort is put into projects designed to protect them.

Galapagos Tortoise Projects

Since Charles Darwin first set foot on the Galapagos Islands in 1835, there has been a dramatic change. It was once a haven of biodiversity that allowed Darwin to begin developing his theory of evolution. He described it as “very remarkable: it seems to be a little world within itself; the greater number of its inhabitants, both vegetable and animal, being found nowhere else.”

Today, Darwin would be disappointed.

The population of giant tortoises that once thrived all over the Galapagos is now down to 10% of its former numbers. However, they’ve also been the subject of one of the most successful and inspiring conservation efforts in history.

In the last six decades, some 9000 tortoises have been raised in captivity and returned to the Galapagos wilderness. Once free, they’ve healed the damaged ecosystem and begun the work of repopulating their own species.

Why are Galapagos Tortoise Projects Important?

Galapagos Tortoise Projects are Important because there are more species of tortoises in the Galapagos than anywhere else on Earth. The Galapagos population is critical to understanding these creatures. What scientists learn there can even have a positive impact on repopulation projects of other species around the world.

Tortoises are Making a Strong Comeback

Among the most amazing and exciting accomplishments is the recovery of the Espanola Giant Tortoise. Due to hunting and invasive species, these tortoises were reduced to only 15 surviving species. Through the conservancy program, the population has now increased to over 2300 individuals.

Most recently, 136 young tortoises were rewilded to their ancestral home on Isabela Island in the Galapagos. These tortoises will live for a hundred years or more. As a keystone species, they represent 136 opportunities to restore the ecology of the Galapagos Islands for the next century and beyond.

That’s an exciting and hopeful promise for the future of our planet.

Diego, the Espanola Saddleback Tortoise, last tasted freedom the better part of a century ago.

He was taken from his home on Espanola Island during the 1930s. He spent years entertaining people at zoos in New York and California.

While Diego was doing that, tremendous changes were happening to his home island. The population of tortoises was disappearing. The estimated 2400 individuals that he had left behind had been reduced to a mere 14 adults. These few remaining animals were so far dispersed that they weren’t going to be able to reproduce.

The Espanola Tortoise was in immediate danger of vanishing forever.

So, the remaining adults, including Diego, were gathered and placed in a captive breeding center on Santa Cruz Island in the Galapagos. There were twelve females and three males.

Of these, Diego was by far the most productive. He’s fathered about 1000 baby tortoises. This amounts to nearly half the number of baby turtles produced in the breeding center to date.

Diego had almost single-handedly saved his species.

Today, around 860 Espanola Tortoises have been released back into the wild and the population is well on its way to recovery.

As for Diego, the old centenarian has finally been allowed to retire. In 2020, he was returned to his home on Espanola Island and released to live in the wild. He’s still carefully monitored by conservationists via a GPS tag attached to his shell.

He is a wild tortoise once again.
