When a team of Dutch scientists unveiled the world’s first stem cell beef burger in 2013, it carried a $300,000 price tag. Worse, it was dry and tasteless. But since the initial lackluster reviews, Mark Post and his colleagues have been hard at work. Now, they say they hope to have a commercially saleable cow-less patty on the market in five years.

Until very recently, lab-grown beef sounded like science fiction. But rapid advances in molecular biology and stem cell technology have placed the futuristic concept within reach. And the arguments for removing animals from the meat equation are practically endless: The meat industry as it exists today swallows an enormous fraction of our land and natural resources, produces vast quantities of greenhouse gases, has contributed to the rise of antibiotic resistant infections, and in many cases, is downright cruel. If test tube burgers can eliminate or diminish even a fraction of these problems, then this seems like one crazy idea worth pursuing.

And pursue it scientists have. In addition to Mark Post’s stem cell burger effort, a team of Israeli researchers under the banner Future Meat are now trying to grow whole chicken breasts in the lab. Meanwhile, efforts to culture fish protein have cropped up intermittently over the years.

Our bodies aren’t meant for space. We require too much maintenance to speed through the stars. We need a steady supply of things absent from space — namely water, food and oxygen. We crave warmth but won’t find it in deep space, where the average temperature is −455 degrees Fahrenheit. Even if we could survive in an icy vacuum without sustenance, we’d probably go insane without distractions and room to move.

But aeronautic engineers believe they have found the key to solving that puzzle: put your space travelers to sleep. Long-term cryogenic and hibernative sleep may be the key to getting humans to Mars, and beyond. But it may first come to a spa near you.

The future of Eco conservation?


Deforestation downs 10 billion trees around the globe annually. Replanting trees by hand is slow, expensive, and barely puts a dent in reversing the damage. But one startup wants to use drones that can reforest our increasingly tree-strapped Earth, on a big enough scale to replace slow and expensive hired humans.

The small company, called BioCarbon Engineering, says unmanned aerial vehicles are a great way of covering ravaged woodlands with seedlings that can repopulate the area’s tree population. Around the world, forests and jungles are still being leveled due to lumber overproduction, strip surface mining, urban expansion, and land use for agriculture.

But UK-based BioCarbon, founded by former NASA engineer Lauren Fletcher, has a plan: Use fixed-wing drones to map the topography of the land, as well as the nutrients and biodiversity. That info is put into a machine-learning algorithm to generate a “precision planting platform,” says Susan Graham, head of engineering at BioCarbon.

Sabine Dziemian, a postgraduate in Faisal’s research group, says, “If I want to draw a straight line, I look at the start point and the end point, and the robot moves the brush across that line.”

Blinking three times puts the robot in color selection mode, in which it moves the brush over to a variety of pre-dispensed colors. At that point, the user only needs to look at the color he or she wants to use next, and the arm applies the color to the brush.

“Since time immemorial, human imagination has sparked the idea of having additional arms,” says Faisal. He invokes the multiarmed Hindu goddess Shiva, often a symbol of transformation, to suggest we might one day “do the dishes while taking a phone call or [holding] your baby and [preparing] the food at the same time, because you have just that extra pair of hands attached to you.”

Sensors and robotics are two exponential technologies that will disrupt a multitude of billion-dollar industries.

This post (part 3 of 4) is a quick look at how three industries — transportation, agriculture, and healthcare/elder care — will change this decade.

Before I dive into each of these industries, it’s important I mention that it’s the explosion of sensors that is fundamentally enabling much of what I describe below.

When humanity needs to make use of a facility known lovingly as the “doomsday seed vault,” you know things have gone off the rails. After four years of civil war in Syria, the region’s main source of important seeds in the region has been damaged, and researchers from the International Centre for Agricultural Research in Dry Areas (ICARDA) is asking to make a withdrawal from the seed bank. This will be the first time humanity has had to draw on this resource.

The Svalbard Global Seed Vault was officially opened in 2008 and contains more than 860,000 samples of seeds from nearly every country on Earth. Its goal is to preserve important agricultural crops like beans, wheat, and rice so they will be available in the event of war or natural disaster.

To do this, the vault is built into the side of a mountain in the remote northern reaches of Norway on the Svalbard archipelago. It’s only 800 miles (1300 km) from the north pole, which allows researchers to keep the seeds at a frosty 0 degrees fahrenheit. Even if all the people left Svalbard and the power went offline, the vault would remain frozen and intact for at least a few centuries.

An art professor from Syracuse University in the US, Van Aken grew up on a family farm before pursuing a career as an artist, and has combined his knowledge of the two to develop his incredible Tree of 40 Fruit.

In 2008, Van Aken learned that an orchard at the New York State Agricultural Experiment Station was about to be shut down due to a lack of funding. This single orchard grew a great number of heirloom, antique, and native varieties of stone fruit, and some of these were 150 to 200 years old. To lose this orchard would render many of these rare and old varieties of fruit extinct, so to preserve them, Van Aken bought the orchard, and spent the following years figuring out how to graft parts of the trees onto a single fruit tree.

Working with a pool of over 250 varieties of stone fruit, Van Aken developed a timeline of when each of them blossom in relationship to each other and started grafting a few onto a working tree’s root structure. Once the working tree was about two years old, Van Aken used a technique called chip grafting to add more varieties on as separate branches. This technique involves taking a sliver off a fruit tree that includes the bud, and inserting that into an incision in the working tree. It’s then taped into place, and left to sit and heal over winter. If all goes well, the branch will be pruned back to encourage it to grow as a normal branch on the working tree.

There are over 500 million hungry people in the world—but that number only tells part of the story. The other part of it is the amount of the actual food shortfall. So how much food would we need to make up the gap? There’s now an exact number.

The latest International Food Security report is out, and the good news is that global food insecurity has been falling—and it’s projected to keep on doing that over the next 10 years. The bad news? It’s not falling everywhere. Sub-Saharan Africa is especially being shut out of these gains.

But how much food would it take to close the gap for every food insecure person on the planet to have access to 2,100 calories a day? The USDA has calculated a figure: 11.8 million tons of grain.
