DailyDirt: Life Abhors A Vacuum
from the urls-we-dig-up dept
Biologists continue to find signs of life in some of the most remote places on Earth. A variety of organisms seem to be able to thrive under harsh conditions that are similar to extra-terrestrial places elsewhere in our solar system. So finding these extremophiles could point us towards good places to find alien life forms on other planets or moons or asteroids... Here are just a few more examples of some really tough microorganisms.- Evidence of life in a subglacial lake in Antarctica has been found, and it could mean that bacteria are much more widespread than we previously thought. Researchers still need to verify this discovery and make sure they're not looking at bacterial contamination from other sources. [url]
- Frost flowers are salty ice crystals that form on calm ocean surfaces, and arctic sea meadows of these flowers may become more common with climate change near the north/south poles. About a million bacteria live in the few milliliters of frozen saltwater of a frost flower, and studying these cells could teach us more about how hardy some extremophile organisms can be. [url]
- Bacteria living below the ocean and at the ocean surface have it easy compared to bacteria that live 6 miles above sea level in the troposphere. Microorganisms could play a role in cloud formation, and there is a lot we don't know about how life survives in different parts of the atmosphere. [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.
