Newly discovered deep-sea worm amazes marine biologists

Marine biologists at the University of California, San Diego’s Scripps Institution of Oceanography and the Ensenada Higher Education and Research Center have described a rare new species of deep-sea insect with gills discovered in a methane well off San Diego’s Pacific coast. Named pectine rice triclotti, the new species has an elongated body flanked by rows of feathery, gill-tipped appendages called lateral legs.

pectine rice triclotti belong to Nereididae, a segmented, mostly marine family of insects with over 700 recognized species.

Commonly known as lugworms, these organisms are generally found in coastal areas and are usually limited to shallow marine habitats, but can also be found in brackish waters, freshwater bodies, and even moist terrestrial environments.

However, around 10% of the total diversity of lugworms is known to inhabit deep-sea environments.

These nematodes have a long body with rows of bristly parapods on the sides and a set of scissor-like jaws for feeding.

Many lugworm species undergo two distinct life stages: atokes and epitokes.

Pectine rice triclotti was first discovered during a dive in 2009 at a depth of approximately 1,000 meters (3,280 feet) using the submersible Alvin.

“We observed two lugworms swimming close to each other, about the length of a submarine, near the ocean floor,” said Bruce Stricklot, a researcher at Woods Hole Oceanographic Institution.

Several specimens of pectine rice triclotti were collected and analyzed for anatomical features and DNA to determine their evolutionary relationships within the Nereididae family.

According to Dr. Greg Rouse, a marine biologist at the University of California, Scripps Institution of Oceanography, Pectine rice triclotti has unique characteristics compared to other lugworms.

Pectine rice triclotti, while possessing menacing-looking jaws, has unknown feeding habits, with the possibility of feeding on bacteria and other large food particles similar to other insects.

The body color of pectine rice triclotti in its natural habitat is likely rosy due to the darkness at 1,000 meters below the surface.

Further research is needed to explore the reproductive mechanisms and feeding behavior of this newly discovered deep-sea species.

The finding is detailed in the article: paper published in the online journal PLoS ONE.

Cutting-Edge UK University Amazes Students with Hologram Lecturer Technology

Any university lecturer will tell you that getting students to come to their morning lectures is a real struggle.

But even the most hungover beginner is sure to be captivated by Albert Einstein’s physics lesson or Coco Chanel’s design masterclass.

This could soon be the case for students in the UK, with some universities inviting guest lecturers from around the world using the same holographic technology used to bring deceased singers back on stage. It’s starting to happen.

Loughborough University, which was the first in Europe to consider applying the technology, has used the technology to bring in sports scientists from the Massachusetts Institute of Technology (MIT) to teach fashion students how to create immersive shows and teach management students how to create immersive shows. plans to test how to handle difficult business situations.

Professor Vicky Locke, dean of Loughborough Business School and who is leading the rollout of the technology, said students “absolutely love” the technology and want to take selfies with it. said. They would prefer “a guest speaker from the industry who walks into the classroom with a smile on their face rather than a two-dimensional person on the wall,” she added.

The Zoom calls made students “feel like they were watching TV… it felt distant,” she said. For them, holographic images are more appealing and realistic. ” The technology will be officially introduced into the curriculum in 2025 after a year of experimentation.

The box-based holographic unit is sold by L.A.-based company Proto. The company’s customers include companies such as his BT and IBM, and it is used in meetings to reduce the need for business travel. We are also collaborating with Stockholm fashion retailer H&M to create an interactive product display.

David Nussbaum, who founded Proto four years ago after working on holograms of deceased celebrities, says his company could soon bring some of the 20th century’s greatest thinkers back from the dead. Told.

He added: “Proto has technology that projects images of Stephen Hawking and other people to make it seem as if he’s really there. We use it in books, lectures, social media, etc. You can connect it to something you were attached to, a question you asked, an interaction you had with him, etc. AI Stephen Hawking looks just like him, sounds like him, and interacts as if it were him. To do.

“It’s awe-inspiring and mind-blowing. I’m shocked at how great the interactions are. Whether people like it or not, AI is part of our lives.”

He added that his company’s ambition is to prove that “you don’t have to be an eccentric billionaire or celebrity to have a hologram.”

Gary Barnett, Professor of Digital Creativity at Loughborough University, who is also leading the implementation, said:

“Students need to understand what it means to use them, to be in that world, to experience them, to interact with them, and all that they will need for their future careers.”

Professor Rachel Thomson, the university’s vice-chancellor and advocate, said the technology could reduce the need to bring in guest speakers at short notice, encourage international research collaboration and reduce the amount of teaching materials used by students. He said it will help achieve sustainability strategies. Building prototypes in engineering, design and creative arts.

It also allows instructors to display complex equipment, such as engines, more easily than over a video call.

Nussbaum said corporations and large institutions such as universities are the first step in his company’s plans, but he hopes to roll out mini-units costing less than $1,000 within the next 18 months, which It will show a miniature image that he likens to the movie “Wonka Vision.” “Charlie and the Chocolate Factory” by Roald Dahl.

He added that the technology’s AI capabilities meant it was possible to create an avatar that looked like anyone in the world, but noted that this could come with legal complications.
