First Direct Imaging of DNA Fibers’ Double Helix

Isn’t it strange that you are made up of perhaps 37.2 trillion cells, almost all of which have a copy of your complete DNA? Here is a first direct image of DNA, the physical structure that holds the instructions used to make you. That dark line in the image is stretched out DNA. The double … Continue reading

Poisonous Frogs with Fluorescent Heads

A strange unique feature of some small Brazilian amphibians was recently discovered: natural fluorescence. In the Brazilian Atlantic forest, pumpkin toadlets (Brachycephalus ephippium) are tiny, brightly-colored, and poisonous frogs. Seen by day, they walk around the forest producing soft buzzing calls in search of a mate. Interestingly, Postdoctoral Associate Sandra Goutte discovered not only that Brachycephalus … Continue reading

Three Babies from Two Wombs in One Woman

Large body movements, tenseness, swaying and fidgeting are very instructive even beyond facial expressions according to research: Be it triumph or crushing defeat, exhilaration or agony, body language more accurately conveys intense emotions, according to recent … Continue reading

Videos: Robot Jellyfish: Underwater and Flying

Today’s strange topic is robotic jellyfish. The idea has been around for a while and there are now several different working models. I got interested in them back in 2013 with this article: Swimming with the Robotic Jellyfish Virginia Tech College of Engineering researchers have unveiled a life-like, autonomous robotic jellyfish the size and weight … Continue reading

DNA transistors pave way for living computers

Have you ever thought about computers made from living cells? Before the Internet (that’s how old I am) I had an idea about self-healing molecular memory. DNA does some of the things needed for this naturally. This is an older article, but still strange and intersting. Two groups of researchers have independently built the first … Continue reading
