New ecosystem found after Chicago-sized chunk of Antarctica breaks off
(NewsNation) — An ecosystem in Antarctica may have existed for hundreds of years, researchers learned after an iceberg the size of Chicago broke off the continent, exposing an area previously inaccessible to humans.
An international team of researchers with the Schmidt Ocean Institute was working in the Bellingshausen Sea, which is located on the west side of Antarctica, when an iceberg broke away from the George VI Ice Shelf on Jan. 13.
The ice was 209 square miles in size, and when it detached, it revealed a whole new world.
By Jan. 25, the explorers reached the sea floor, becoming the first to investigate this uncharted area.
'Being right there when this iceberg calved from the ice shelf presented a rare scientific opportunity,' said Schmidt Ocean Institute Executive Director Dr. Jyotika Virmani in a news release. 'Serendipitous moments are part of the excitement of research at sea – they offer the chance to be the first to witness the untouched beauty of our world.'

The team, which included scientists from the United States, Chile, Germany, Portugal, New Zealand, Norway and the United Kingdom, used a remotely operated vehicle, ROV SuBastian, to observe the deep seafloor for eight days.
They found animal and marine life as deep as nearly 4,300 feet. The species in the newly discovered ecosystem include crustaceans, sponges, corals and octopus, many of them never seen before.
'The discovery offers new insights into how ecosystems function beneath floating sections of the Antarctic ice sheet,' the release said.
'We didn't expect to find such a beautiful, thriving ecosystem. Based on the size of the animals, the communities we observed have been there for decades, maybe even hundreds of years,' said expedition co-chief scientist Dr. Patricia Esquete at the University of Aveiro Portugal, in the release.

Rosemary, sage could boost brain health: Study
(NewsNation) — A recent study has found that rosemary and sage may have a positive impact on brain health and reduce the risk of Alzheimer's disease. The study released in the Antioxidants journal shows a compound shared by the two herbs called carnosic acid has antioxidant and anti-inflammatory properties that shield brain cells from damage similar to what can lead to Alzheimer's. Researchers were able to create a more stable form of carnosic acid called diAcCA. Screen time a symptom, cause of emotional distress in kids: Study In preclinical studies, the researchers found that the compound improved memory, boosted brain synapses and reduced harmful Alzheimer's-related proteins like amyloid-beta and tau. The diAcCA compound only activates in inflamed brain regions, which could minimize side effects. To date, studies in mice have shown significant cognitive improvements and no signs of toxicity. Researchers are looking to start human trials soon. Researchers also believe diAcCA could help treat other inflammatory conditions, such as Type 2 diabetes, cardiovascular disease and Parkinson's disease. Copyright 2025 Nexstar Media, Inc.

‘Gargantua' deep-sea creature among new species found in Atlantic. See them
In the depths of the Mid-Atlantic Ridge, underwater volcanoes spew material into the ocean water. Vents that connect underground rifts to the surface release billowing clouds of black deposits of iron sulfide, earning the moniker 'black smoker chimneys.' These hydrothermal vent fields are hot, chemically rich and toxic to most forms of life. But, a special few organisms have adapted to call them their home. Now, two new species found around the black smoker chimneys of the Hydra and Falkor hydrothermal vent fields have been identified — and they're huge. Researchers operating the remote underwater vehicle SuBastian, from the Schmidt Ocean Institute, and the human-occupied vehicle Nautile, from the French Institute of Research and Exploitation of the Sea, used suctioning tools to collect peltospirid gastropods from the black smokers, according to a study published June 5 in the peer-reviewed Zoological Journal of the Linnean Society. The peltospirid gastropods, or a family of marine snails found around hot vents, were compared to known species, but their 'very large' size immediately tipped off researchers that they may belong to new species. Genetic testing confirmed their suspicions, according to the study. The first new species, Peltospira gargantua, was found on a black smoker chimney in the Hydra field at a depth of about 12,300 feet, researchers said. With a shell smaller than an inch, the snail is 'very large' compared to others in their genus, researchers said. The shell is 'rather tightly coiled,' and their bodies have 'short, paddle-like' tentacles. Part of the shell is an 'olive green' color, but the shells are typically 'obscured by dark brown to reddish layers of' mineral deposits, according to the study. 'The head is large, with a thick and broad snout that expands slightly towards the mouth,' researchers said of the snail's body. The animals have no trace of eyes on their external bodies, not uncommon for creatures found in the dark abyss of the Atlantic. Researchers named the species after Gargantua, a character from the French novels 'The Five Books of the Lives and Deeds of Gargantua and Pantagruel,' stories of a giant king and his son. 'The word Gargantua has since been used to mean 'huge' or 'immense,' as exemplified by the English adjective gargantuan,' according to the study. 'Thus, the species name refers to the very large size of the new species in relationship to other known (relatives).' The second new species, from a different genus, was named after Gargantua's son, Pantagruel, according to the study. Lirapex pantagruel is the 'largest of all known Lirapex species, hence the name of a giant is fitting,' researchers said. The species was found on the black smokers of the Falkor hydrothermal vents at a depth of about 13,000 feet, according to the study. This species is even smaller, with a shell diameter of about 0.3 inches long, and the shell is 'tightly coiled,' researchers said. The pantagruel snail is also covered in reddish to blackish material, but has a semi-transparent and greenish hue otherwise. 'The soft parts are overall typical of the genus Lirapex,' researchers said. 'The head is large and without pigmented eyes… The snout is short, flattened, with the mouth opening ventrally. A pair of thin, film-like jaws are present.' Finding the two new species was a 'surprising discovery,' researchers said, as the areas where they live have only been explored for a few years. 'Hydrothermal vents on the northern (Mid-Atlantic Ridge) have been explored for about four decades. Yet, species of large snails aggregating in conspicuous habitats near hot fluid orifices, such as P. gargantua and L. pantagurel, have remained undiscovered until now,' researchers said. 'It might be that the two new species are present only in Hydra and Falkor EMARK, two vent fields that were found only in 2023.' The research team includes Chong Chen, Florence Pradillon, Coral Diaz-Recio Lorenzo and Joan Manel Alfaro-Lucas.

Ohio State University going all in on AI to build ‘intuition': Provost
(NewsNation) — As artificial intelligence continues to be hotly debated in the United States, one college is going all in on letting the capability of computational systems perform tasks typically associated with human intelligence. Ravi Bellamkonda, provost and executive vice president at Ohio State University, joined 'NewsNation Live' to discuss the school's 'AI Fluency Initiative' beginning this fall. The 'AI Fluency Initiative' will be required of all students at the school. The hope is that the program will help students become bilingual, meaning fluent in their major field of study and applying AI in that area. 'We've been using all sorts of tools to augment learning, augment our understanding of the world,' said Bellamkonda. 'There's no question we live in a data-rich world now, from politics, to news, to manufacturing, to medicine, to all these fields of study and interest for our students. We have lots and lots of data. And the power of AI is to synthesize that data and make meaning out of it.' Regulating AI for ten years in 'big, beautiful bill' no help: Tech expert Pew Research Center said that in 2024, teens reported using AI twice as much as they did the year before. Over half say they think it's okay to use AI for research, while nearly 30% acknowledge it's acceptable to use AI for math problems. Less than 20% added that it's okay to use AI to write an essay. 'We really want to build intuition, judgment, and ethical understanding,' Bellamkonda said. 'When is it appropriate? When is it not appropriate? When is it hallucinating? When is it not? And we feel like having that conversation in the classroom with a professor in the context of the subject they are learning is really important for us.' High school students create AI-detecting app to help teachers Apple says it has a new research paper out that says artificial intelligence might not be as intelligent as some want it to be. The company's new research paper claims that so-called 'large reasoning models' and 'large language models' such as ChatGPT give up when trying to solve complex problems. Their researchers say this is proof of limited capabilities that keep artificial intelligence from reasoning the way you or I do. 'We had the same fear, if you remember, when we had calculators,' added Bellamkonda. 'We were afraid that people would store formulas in there and not really understand. That's the challenge we have as educators now is to still make sure that our students have a deep understanding of the subject and they're not just letting AI do all the thinking.' How AI is shaping industries across the US Bloomberg also reported that Mark Zuckerberg, founder of Facebook, is seeking a team to build an AI that could reason on the same level as a human. He wants to hire around 50 people for the project. This comes after Meta delayed the release of a big new artificial intelligence model last month over concerns it wasn't good enough. In addition, St. Petersburg, Florida, is installing AI or so-called 'smart signals' that can connect with tech in some newer vehicles. That tech can alert the driver about upcoming hazards and traffic conditions, such as flooding or a pedestrian in the area. The city is looking to invest more than $1 million in the project.
