MIT Unveils Puffin-Inspired Robot That Flies and Dives to Explore Oceans

MIT engineers built a lightweight, puffin-inspired robot capable of both flight and underwater swimming. The craft uses a 34.5-inch wingspan, waterproofed components, and a motorized tail; in air it flaps at 5–6 Hz and can sprint above the water, while underwater it uses its wings to swim and stays level without sinking. Weighing about 250 g, it can fly about 6 km on a full charge and swim roughly 2 km underwater. Tested in a lab tank and Lake Geneva, the team envisions using the robot to study coral reefs, track fish, and monitor algae, potentially carrying it to remote sites to collect samples or data.

Plastic at the Hadal Depth: The Challenger Deep Sighting and the Broader Deep-Sea Debris Trend

Plastic at the Hadal Depth: The Challenger Deep Sighting and the Broader Deep-Sea Debris Trend

In 2019 Victor Vescovo reached about 10,927 metres in the Challenger Deep and reported seeing something that looked like a plastic bag, but the observation was hedged and not recovered; subsequent analysis notes that a JAMSTEC study had already logged a plastic bag at 10,898 metres, and broader research shows single-use plastic debris is common at hadal depths, making the general claim of plastic in the deep sea well-supported even if the specific bag sighting isn’t definitively confirmed.

NOAA Solves Golden Orb Mystery: Remnant of a Giant Deep-Sea Anemone

NOAA researchers solved the nearly three-year mystery of the “golden orb,” finding it is not an egg, sponge, or alien but a remnant of dead cells that attached to rock at the base of the giant deep-sea anemone Relicanthus daphneae. Initial DNA barcoding was inconclusive, but whole-genome sequencing confirmed animal DNA and a close match to Relicanthus daphneae, after the orb was collected during a 2023 Gulf of Alaska expedition and sent to the Smithsonian for study.

Gulf of Alaska’s golden orb traced to a giant deep-sea anemone relic

NOAA and the Smithsonian have identified the 2023-found 'golden orb' in the Gulf of Alaska as a remnant of Relicanthus daphneae, a rarely seen giant deep-sea anemone, specifically the anchoring base attached to rock. The fibrous, stinging-cell mass initially puzzled scientists, but multidisciplinary analysis confirmed its cnidarian origin and linked it to the same species observed in the Mariana Islands, highlighting ongoing deep-sea mysteries revealed by expeditions like Seascape Alaska 5.

Unveiling the Ocean's Nightmares: Bizarre Deep-Sea Creatures Discovered

The article describes the fascinating and mysterious barreleye fish, a deep-sea creature with a transparent head and upward-facing tubular eyes that can rotate forward, allowing it to see in the dark depths of the Pacific Ocean. Its unique adaptations for survival in the midnight zone have intrigued scientists, especially after a 2009 expedition captured live footage, revealing new insights into its anatomy and behavior. The fish's features may inspire technological innovations, and it remains a symbol of the vast, largely unexplored ocean depths.
