Federica Bertocchini’s discovery that wax worms can eat through plastic happened completely by accident. Bertocchini, an amateur beekeeper, was dismayed to find that her beehives were infested by wax worm caterpillars. After cleaning out the hive, she went to pick up the plastic bags she had placed the pests in, only to find the bags riddled with holes.   [Read more…]

The Demise of the Cavendish Banana

Whether sliced into a bowl of cereal, split in two and served with ice cream, or peeled and eaten, the banana is a common part of the American diet. Americans eat more bananas annually than oranges and apples combined. Bananas are an excellent source of vitamins, including B6 and C, magnesium, potassium, and fiber. While Americans typically view bananas as a snack food, in other parts of the world, they hold a much more important nutritional role. In some areas of Africa, where more than 200 species of the fruit are grown, bananas account for 80% of consumed calories. However, the banana that you know and love – a variety called the Cavendish – is in danger of being wiped out by a catastrophic disease currently spreading across the globe.

The Holocene Epoch began around 12,000 years ago. Are we now in the Anthropocene? In a recent study published in Science magazine, some scientists argue that we indeed have entered a new epoch. [Read more…]

While botanic gardens might seem like just a pretty or relaxing place to visit, it turns out they hold a very important role in the global conservation and preservation of threatened and endangered plant species. However, some researchers think botanic gardens should be taking an even bigger part in ensuring that threatened and endangered plant species are protected from extinction. [Read more…]

While not exactly a new technology, fracking (which is short for “hydraulic fracturing”) has been a common topic in the news recently. Fracking is known both for its potential to ease U.S reliance on foreign sources of energy and for its possible adverse effects on the environment, which scientists now think include the potential for starting earthquakes.

Every month, an average of 40 volcanoes erupt on land into the atmosphere, and hundreds of others on the seafloor erupt into the ocean. Predicting when these eruptions will occur is nearly impossible. Scientists associated with the Deep Carbon Observatory (DCO) and Deep Earth Carbon Degassing (DECADE) initiative are setting the stage to make accurate volcanic eruption forecasts a reality.
