The most important set of genetic instructions we all get comes from our DNA, passed down through generations. But the environment we live in can make genetic changes, too.

Researchers have now discovered that these kinds of environmental genetic changes can be passed down for a whopping 14 generations in an animal – the largest span ever observed in a creature, in this case being a dynasty of C. elegans nematodes (roundworms).

To study how long the environment can leave a mark on genetic expression, a team led by scientists from the European Molecular Biology Organisation (EMBO) in Spain took genetically engineered nematode worms that carry a transgene for a fluorescent protein. When activated, this gene made the worms glow under ultraviolet light.

Amazon’s Echo smart speakers just went in an unusual (but potentially very helpful) new direction. Meet Echo Look, an Alexa-powered camera designed around taking your own fashion photos and videos. If you want to show off your daily wardrobe, you just have to ask the Look to take a snapshot — you don’t have to take a selfie in front of a mirror to get a full-length picture.
