10 Interestingly Scary Examples of Genetic Engineering You Should Know About

Banana
Banana vaccines
Bananas may be the way vaccines are administered to people in the future. Researchers have successfully engineered bananas, potatoes, lettuce, carrots and tobacco to produce vaccines, but they say bananas are the ideal production and delivery vehicle.
When an altered form of a virus is injected into a banana sapling, the virus’ genetic material quickly becomes a permanent part of the plant’s cells. As the plant grows, its cells produce the virus proteins — but not the infectious part of the virus. When people eat a genetically engineered banana that contains the virus proteins, their immune systems theoretically will build up antibodies to fight the disease, just as traditional vaccines are designed to do.

Chemotherapy Eggs
British scientists are breeding genetically modified hens that produce cancer-fighting medicines in their eggs. The birds have had human genes added to their DNA so that human proteins are secreted into the whites of their eggs, along with complex medicinal proteins similar to drugs used to treat skin cancer and other diseases. The hens lay eggs that have miR24, a molecule with potential for treating malignant melanoma and arthritis, and human interferon b-1a, an antiviral drug that resembles modern treatments for multiple sclerosis.

Democracy needs journalism it can trust.

This election season, the stakes are higher than usual — and so is the pressure on newsrooms to soften their coverage, stay quiet, or just disappear. Independent reporting, the kind that answers to readers instead of advertisers or political pressure, matters more in a moment like this, not less.

For over 14 years, Atlanta Black Star has stayed independent and reader-funded. We have no corporate owner and no shareholders telling us what to cover or how to cover it. That independence is also our biggest vulnerability: nothing protects it except readers choosing to fund it directly.

Newspaper ad revenue has fallen more than 80% since 2005, and local newsrooms are closing at a rate of roughly two a week nationwide. When outlets go under in a moment like this, it's rarely the independent, reader-funded ones that get to stick around.

We know a request for support isn't why you came here. But without readers choosing to fund this work directly, the depth of reporting we can do at home and abroad shrinks along with everyone else's. If you're not in a position to give, that doesn't change how much we value you as a reader.

If you are able to, a recurring contribution does more for us than a single one-time gift, because it lets us plan the next investigation instead of just the next invoice. It takes about 30 seconds, no long form, no account. Thank you for continuing to support independent journalism and freedom of the press.
