A huge, gaping cave has been discovered hidden in the remote Canadian wilderness, and despite the overwhelming scale of this stunning natural void, researchers suggest it may never have been seen by human eyes before.

Nicknamed the ‘Sarlacc Pit’ after the monstrous pit-dwelling beast in Star Wars, the giant cave – concealed amidst the rugged terrain of British Columbia’s Wells Gray Provincial Park – is so vast its effectively unbelievable, explorers say.

“My immediate reaction was that there can’t be a cave there, it’s impossible,” geoscientist Catherine Hickson, who conducted an expedition to the site in September, told Global News.

Matter is all around us. As human beings, we’re made of it. Matter is the “stuff” that makes up the physical world as we know it; a collection of atoms made up of particles called protons, electrons and neutrons.

Part of my work, as a post-doctoral researcher at iThemba LABS (Laboratory for Accelerator Based Sciences) in Cape Town, South Africa, focuses on neutrons. These are subatomic particles that can penetrate through matter, which means they can be harnessed for all sorts of important work.

For example, high-energy neutrons may be used to destroy tough tumours that can’t be killed by the usual x-rays that are available in hospitals.

Critics say that geoengineering efforts are Band-Aid solutions that treat the symptoms of climate change instead of the cause: global carbon emissions. Jim Thomas, the co-executive director of an environmental advocacy organization called the ETC Group, told Nature that he fears the Harvard project could push the concept of geoengineering into the mainstream.

But advocates say that anything that could buy some extra time in the face of looming climate catastrophe is worth exploring.

“I’m studying a chemical substance,” Harvard researcher Zhen Dai told Nature. “It’s not like it’s a nuclear bomb.”

I’m Caleb Harper, principal investigator and director of the Open Agriculture initiative at the MIT Media Lab. Kent Larson courtesy of MIT Media Lab.

In his book Tomatoland: How Modern Industrial Agriculture Destroyed Our Most Alluring Fruit, Barry Estabrook details how grocery store tomatoes are both less nutritious and delicious than those grown decades ago. Industrial farming now grows crops for yield, sacrificing taste and vitamins for an easy-to-harvest, shippable product. It’s why apples at your local supermarket are probably about a year old. Caleb Harper, a principal research scientist at MIT and director of the OpenAg Initiative, wants to use technology to grow food that’s healthier, tastier, and more sustainable.

“Growing for nutrition and growing for flavor, it’s not really something anyone does,” he told Digital Trends at the recent ReThink Food conference in Napa, California.
