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.

As promising as a drug candidate may be, the unfortunate truth is that not all of them end up performing as hoped – but that doesn’t mean they’re completely useless. Researchers at Oxford University have managed to give second life to an experimental cancer drug known as tasquinimod, which has now shown promise in preventing Parkinson’s.

Twenty-five years ago today, a group of astronauts ascended in the space shuttle to accomplish a feat of unprecedented proportions: to fix NASA’s Hubble Space Telescope, in space. Learn how the ingenuity of those repairs blazed the way for decades of not only satellite repairs, but also space exploration: https://go.nasa.gov/2FWHuXz&h=AT1qFoI48_v6tgpXkkQf7uBHIj2XuhOHEM-IwOR_0eTc9Hl45Y1vTVfmzIycSONzoRHo0TLWBdjcYFh6Hm_FMi5fcr6glN5T_RvmId7m-zvgEwgruMEFZliTuZwPKE5WIXQyMzlOFL0ZffwF6-eYof6uRckXci34715FbDl3JNBEjlZErelV8A

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.
