You Can Thank Genetic Engineering For Your Delicious Cheese

It used to be that making cheese meant killing cows. Young cows, specifically—a few days old, at most. The stomach of an unweaned calf produces enzymes that turn liquid milk into good, hard, flavorful cheeses like Parmesan and Cheddar. These enzymes, called rennet, are secreted by mucous membranes that line the calf’s… » 6/15/15 3:17pm 6/15/15 3:17pm

The U.S. Just Approved Its First GMO Apple, Which Doesn't Turn Brown 

For years, a small Canadian company, Okanagan Specialty Fruits, has been touting its Arctic apple, which doesn't turn an unsightly brown after being sliced. The U.S. Department of Agriculture finally approved it for planting this week. But before you see any Arctic apples at the grocery store, get ready for a big… » 2/14/15 12:00pm 2/14/15 12:00pm

Could Genetically Engineered Bacteria in Your Colon Replace Vitamins?

It's easy to forget how horrifying the effects of a vitamin deficiency can be. Each year, up to 500,000 children in the developing world go blind from lack of vitamin A, half of whom will then die within 12 months. The molecule that could save their lives is so well-studied and abundant, yet we haven't figured out how… » 2/04/15 2:40pm 2/04/15 2:40pm

Scientists Are Reinventing Photosynthesis to Grow More Food

What if we could grow rice and wheat with the same amount of water and fertilizer but end up with 50 percent more food? Sound like magic? Bad accounting? No, just some chemistry and genetic engineering. Scientists have recently figured out the second of three steps to make photosynthesis a whole lot more efficient in… » 9/17/14 3:17pm 9/17/14 3:17pm

NASA Is Engineering Space Bugs To Produce Bricks on Mars

There's a fundamental stumbling block when it comes to building a base on Mars, and that's getting all the building materials there in the first place. No problem, though, because NASA is busy engineering space bugs that will turn the crap on the planet into building materials to help make the hostile planet habitable. » 10/05/12 8:45am 10/05/12 8:45am
