Caltech researchers have developed a novel approach to deep ocean exploration: using jellyfish as biohybrid robots. They transformed these simple marine creatures into efficient data-gathering devices capable of measuring crucial ocean parameters by equipping them with electronics and a streamlined “hat.”
These augmented jellyfish robots, each costing only about $20 to equip, can swim 4.5 times faster than their natural counterparts while carrying payloads larger than themselves.
The researchers say that swarms of these robots could allow exploration of extreme environments like the Mariana Trench, potentially offering new insights into the effects of climate change on our oceans.
The team is focusing on long-term simulation studies and exploring biodegradable electronics to minimize ocean pollution. We also take a look at Seawise Giant- the rise, rebirth, and fall of the world’s longest ship in our Must Reads.

The Seawise Giant, the world’s longest and heaviest ship ever built, had a remarkable journey spanning over two decades. At 1,504 feet long and with a cargo capacity of over 564,000 tons, this supertanker was longer than the Eiffel Tower and required nearly three square miles to turn and over five miles to come to a complete stop from top speed.
Despite being sunk by Iraqi forces in 1988, the Seawise Giant was salvaged and rebuilt, continuing its career under various names, including Happy Giant, Jahre Viking, and Knock Nevis.
As shipping trends changed and smaller, agile vessels took prominence, and the giant tanker found itself spending its final years as a stationary storage facility in Qatar. Nevertheless, the sheer size of the Seawise Giant attracted media attention, featured in TV shows and documentaries. (Read More)
