Scientists Just Grew Edible Plants in Simulated Mars Soil

Chefs may be able to start drafting a menu for Mars-bound astronauts. A group of Dutch scientists have successfully harvested a crop of edible plants from simulated Mars soil.
Researchers from Wageningen University in the Netherlands have been using soil developed by NASA, which simulates a Martian environment to run their experiments. Mars' soil contains such metals as aluminum, copper, iron, manganese, zinc, arsenic, cadmium, chrome, nickel, and lead. “If too high levels of heavy metals from the soil are absorbed in the edible parts of the plants, the crops become poisonous,” the Mars One office told Popular Science. So, the team has been experimenting with a number of plants since 2013, and it was only recently that they were able to harvested their first edible crops from this soil.
Watch as senior ecologist Wieger Wamelink talks about the trials of the experiment:
Of the crops that grew, they found radishes, peas, rye, and tomatoes were safe for consumption. Though, no one from the team has actually conducted a taste-test on these crops, Wamelink remarked in a press release that he’s “very curious what they will taste like.”
The research was funded by Mars One, a project that hopes to send a group of volunteers on a one-way trip to the Red Planet.
Other groups of scientists have been working on solving the Martian food issue. Earlier this year NASA teamed up with the International Potato Center (CIP) in an effort to find out if the potato will be part of the Mars mission. The team is currently experimenting with 100 different varieties of potato to try and find those best suited to grow on the Red Planet.

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.
- There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
- CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
- Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
- Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.
Protected animals are feared to be headed for the black market.
In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
- The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
- Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
- Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
