Technology Creates Virtual Wall Around Wildlife Preserve
South Africa, which has the largest population of rhinos in the world, has been the country hit hardest by poaching. Between 2007 and 2015, there was a 9,000% increase in poaching there, reaching a high of 1,215 animals in 2014. While numbers have been declining since then, poaching remains a problem. But as Faith Lapidus reports, technology is helping turn one game reserve into a high-tech fortress.

Scientists Study Tiny Creatures With Big Impact on the Ocean
It’s not just human workers who commute each day. Millions of tiny creatures that form the base of the ocean food chain migrate in giant swarms each night. They go up and down - from deep waters to the surface to feed, then back to the depths as dawn breaks. Scientists are looking at how this vertical commute affects the ocean, which is a key regulator of climate by storing and transporting heat, carbon, nutrients and freshwater around the world.

Ice Harvesting Tradition Continues for 120-Plus Years
Americans have not needed iceboxes to keep food cold for nearly a century, ever since refrigerators became widely available. But that doesn't stop folks in Holderness, N.H., from carrying out a winter task that's been done for more than 120 years — harvesting ice for the summer months. Faith Lapidus reports.

Life in Limbo: Leftover Embryos Vex Clinics and Couples
Infertile couples who want to have a child may decide to use In Vitro Fertilization. It's a procedure, in which eggs retrieved from the woman and sperm from the man are combined in the lab, where fertilization occurs. The embryos may then be placed in the woman's womb. But many couples freeze the embryos. They can test them for health problems and transfer the most viable, one at a time. Often some are leftover. And as Faith Lapidus reports, there are questions about what to do with them.

Can Cancers be Detected Early by Smell?
Cancer in your esophagus, the tube that runs from your throat to your stomach, is one of the most frequently reported and a leading cause of cancer deaths around the world. Most cases are reported in developing countries. Early esophageal cancer typically causes no symptoms. However, its chemical markers are present in the earliest stage. A new device being tested in England takes advantage of that to allow early detection of esophageal and other types of cancer. Faith Lapidus reports.

After Christmas, New Purpose for the Tree
There are a number of reasons why Americans like to have a live tree for their Christmas centerpiece It just smells like Christmas, they grew up with a real tree, they feel it's better for the environment than an artificial one.

Centuries-Old Art of Blue-Dyed Cloth Honored
Blue was a rare, expensive color in ancient times, whether it was derived from lapis lazuli mined in Afghanistan some 6,000 years ago, made by blending copper with other elements throughout the Middle East and in ancient China, or mixing an extract of the indigo plant with clay and resin by Mayans in Mesoamerica. Now, a centuries-old tradition of dyeing blue cloth with delicate patterns in parts of eastern Europe has been recognized for its cultural importance by UNESCO. Faith Lapidus reports.

Artificial Intelligence Helps Sniff Out Suspected Secret Nuclear Weapons Programs
Scientists with the complicated task of tracking secret nuclear weapons developments around the world are getting some help from a new and more-advanced artificial intelligence system. Nuclear explosions, even underground ones on the other side of the world, leave signature traces of radioactive gasses. This system helps sort through masses of data to find which radioactive traces are relevant and which are naturally occurring, which are new and which are left-overs. Faith Lapidus reports.
