'Lost World' Discovered in Antarctica
Communities of species previously unknown to science have been discovered on the seafloor near Antarctica, clustered in the hot, dark environment surrounding hydrothermal vents.
What's the Latest Development?
For the first time ever, scientists have explored the East Scotia Ridge deep beneath the Southern Ocean, discovering a trove of new species including a yeti crab, starfish, barnacles, sea anemones—even an octopus. Vents on the sea floor spewing water from beneath the surface reach temperatures of over 700 degrees Fahrenheit, providing for an environment rich in chemicals though lacking in sunlight. Rather than take energy from the sun, these species breakdown chemical compounds like hydrogen sulphide.
What's the Big Idea?
Scientists were as surprised by what they found as what they didn't find. Many animals such as tubeworms, mussels, crabs and shrimp found near vents in other oceans were not present in the Southern Ocean. Leader of the research, Alex Rogers of Oxford University, commented on the diversity found in the world's oceans. "Everywhere we look, whether it is in the sunlit coral reefs of tropical waters or these Antarctic vents shrouded in eternal darkness, we find unique ecosystems that we need to understand and protect."

Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
Lauren Miranda sent a nude selfie to a boyfriend years ago. Somehow one of her students discovered it.
- Math teacher Lauren Miranda was fired from her Long Island school when a topless selfie surfaced.
- Miranda had only shared the photo with her ex-boyfriend, who is also a teacher in the school district.
- She's suing the school for $3 million as well as getting her job back, citing gender discrimination.
An innovation may lead to lifelike evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
