DailyDirt: Biological Discoveries
from the urls-we-dig-up dept
Biology has created some really strange animals -- not just the duck-billed platypus, but all sorts of extremophiles along with senses that sound like they belong in comic books and not in nature. Here are just a few examples.- The jellyfish species, Turritopsis nutricula, can exhibit immortality under the right conditions. And it's spreading across the globe by hitchhiking in ship ballast water. [url]
- People who say they can sense magnetic fields might not be totally crazy. There's a light-sensitive protein in the human eye (a protein that is found in almost every animal, too) that can respond to magnetic fields. [url]
- A nematode worm that lives about 2 miles below the Earth's surface in a South African gold mine can exist happily with very little oxygen as long as it can eat thousands of bacteria every day. Halicephalobus mephisto is the first complex life form found at such an extreme depth. [url]

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Magnetic sense
The actual magnetic sensing requires interactions with (at least) one other protein, which is not present in humans.
So those people probably are still just crazy.
