DailyDirt: Strange Forms Of Life...

from the urls-we-dig-up dept

Nature has plenty of surprises left for us. Life exists in some extreme environments that you wouldn't think anything would survive, but somehow little creatures are still thriving in some of the coldest, darkest, most acidic, hottest and just unusual places. Life just needs to be able to feed on something -- light, sugar, electricity. Here are just a few bizarre discoveries in biology. After you've finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

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.

    Photosynthesis requires breathing

    I am not a specialist biologist, but my courses in such did highlight that all plants that use photosynthesis also breathed in CO2 and breathed out O2, and when not doing photosynthesis at night breathed out CO2 and breathed in O2.

    Hence, metabolising sunlight will still require some sort of breathing on the part of organisms.

      Well, technically, if you're going to nit-pick on the breathing, plants need to "eat" too, right?

      I think the suggestion here is for there to be some kind of way to avoid "traditional eating/breathing" by having algae in your skin to produce sugars and oxygen directly into your bloodstream. Not that any organism would be able to avoid any kind of respiration entirely.

        Yeah, well when no sunlight, CO2 into blood stream instead of O2. Somewhat problematic.

          Should have also added that photosynthetic cells would then be using sugars from body when no sunlight, Also problematic.

    The problem with humans photosynthesizing is that humans burn energy several times faster than a human-skin-sized area receives sunlight. We'd have to either spend the entire day standing out in the sun while remaining perfectly still 24/7 in order to conserve energy, or else get ten square yards of extra skin surface to collect more sunlight.

      Sounds an awfully lot like trees. ALL HAIL THE ENTS!

    Before Then We Have Breatharians

    Some people claim they need nothing more than air (specifically a substance known as prana, aka life air) to survive (thrive? I'm not sure if they claim that).

    When I first met my wife there was a time I didn't need to eat or sleep. Maybe it's like that.

    I could never imagine living in such a euphoric state like that for too long, as it seems to have a significant impact on one's health. But maybe some have figured out how to leave The Matrix and so normal rules don't apply to them.
