French company Seabike has developed a unique swimming device that harnesses your leg power to propel you through water at remarkable speeds. This crank-driven pusher prop, resembling an underwater unicycle, promises an exhilarating aquatic experience.

The concept behind this “underwater mobility device” is straightforward. You adjust the Seabike’s pole to the desired length and secure it to your waist with a belt. Then, you place your feet on the pedals and start cranking, using the waist strap for support. This action drives a propeller, roughly 15 inches (38 cm) in diameter, propelling you through the water with the smooth grace of a cruising dugong.

In a remarkable feat of engineering, six aircraft, including an 8-pound personnel recovery system, were assembled within a mere 22.5 hours before their launch. This innovative method was spearheaded by the Air Force Center for Strategy and Technology’s Blue Horizons mission, a visionary think-tank dedicated to advocating unconventional strategies to meet tactical demands.

The driving force behind this project was the three-person Black Phoenix crew, selected from among the five teams concluding year-long Blue Horizons fellowships. Their focus centered on the rapid adaptation of small Unmanned Aerial Systems (UASs), their technology, and payloads to suit diverse operational environments.

In recent years, the spotlight on bioengineered plants and genetically modified organisms (GMOs) has intensified, particularly concerning their implications for food production and food security. Yet, amidst the media fervor, there persists a notable lack of public awareness regarding the intricacies of bioengineered plants and the spectrum of advantages and disadvantages associated with genetic modification.

Traditionally, household plants such as the Marble Queen Pothos have been celebrated for their modest air-purifying capabilities. However, their efficacy has been constrained, often necessitating a substantial number of plants to make a tangible impact on indoor air quality.

DARPA has finally lifted the veil on its secretive Manta Ray robotic sub, revealing impressive new images of the prototype Uncrewed Underwater Vehicle (UUV) as it undergoes its inaugural sea trials off the coast of Southern California.

Resembling a fusion of the B-21 Raider bomber and a relic from a 1960s science fiction series, the Manta Ray exudes an air of mystery. While DARPA has provided some insights into the sub, essential details regarding specifications and performance have been shrouded in secrecy. Positioned to spearhead a new era of UUVs characterized by extended range, prolonged endurance, and versatility in handling various payloads, the Manta Ray offers a revolutionary approach to underwater operations.
