Innovative Jellyfish Modification by Caltech Researchers Opens New Avenues for Ocean Exploration
A professor and a graduate student at the California Institute of Technology (Caltech) have embarked on a groundbreaking project to explore the ocean in an unconventional way. Unlike typical genetic modifications, their approach is purely engineering-based. They've designed a bumper, resembling a cap, that significantly enhances the jellyfish's hydrodynamic properties. This innovation follows their previous success in implanting a device akin to a pacemaker, which encourages the animal to swim faster. Combined, these modifications enable the jellyfish to swim at speeds up to 4.5 times faster than their unaltered counterparts.
The primary goal of these biohybrid robotic jellyfish is to gather critical data on the ocean's chemical composition, temperature, oxygen levels, and more. The sensors required for these measurements are conveniently housed within the 3D-printed conical structure attached to the jellyfish. Remarkably, each modified jellyfish costs about $20, presenting a cost-effective alternative to the exorbitant daily expenses of over $50,000 associated with chartering a research vessel.
The researchers emphasize the ethical aspect of their work, noting that jellyfish lack a brain and the capacity to experience pain. Therefore, these laboratory modifications do not inflict suffering on the animals. This innovative approach not only paves the way for more efficient and humane oceanic research but also demonstrates the potential of biohybrid systems in environmental monitoring.
Stay tuned for more updates on this fascinating intersection of biology and engineering as we continue to explore the mysteries of the ocean in sustainable and innovative ways. @science

The slime mold Physarum polycephalum, a unicellular mixomyceate typically found on decaying wood, displays a form of species-specific genius. Renowned for its remarkable ability, colonies of this organism can find the shortest path between two points in a maze, a skill reminiscent of rats known for their superior maze-navigation abilities compared to humans. However, the slime mold's talent diverges in its capacity to form optimal distribution networks and solve complex computational problems related to spatial organization. Despite its unicellular nature, which might imply limited capabilities, its species-specific genius has been employed in various fields, from logistic models to modeling the large-scale structure of the cosmic web of the universe.

On February 17th, a plasma jet erupted near the Sun's south pole, reaching an altitude of 200,000 kilometers before detaching and drifting into space. This massive plasma cloud is now slowly dissipating as it travels through the cosmos. Unlike most solar flares that occur near the equator, the unusual location of this flare signals the Sun's approach to the most active phase of its 11-year cycle, known as the solar maximum.

Fish That Shouts Louder Than a Gunshot
German ichthyologists have made a fascinating discovery involving the Danionella cerebrum species of fish. Remarkably, these fish can produce sounds exceeding 140 decibels, louder than the noise of a gunshot. What makes this even more astonishing is the size of these creatures; they are tiny, semi-transparent fish with body lengths not exceeding 12 millimeters.
The Danionella species are equipped with a unique sound-producing apparatus comprising a drumming cartilage, a specialized rib, and a fatigue-resistant muscle. This mechanism accelerates the drumming cartilage with a force of over 2000 g, striking the swim bladder to create a rapid and loud pulse. These pulses amalgamate to generate loud signals.
Scientists believe that this deafening noise serves a vital communication function for the fish in the murky rivers of Southeast Asia, where they reside. This discovery not only adds to our understanding of aquatic life but also highlights the extraordinary adaptations of even the smallest creatures in nature.

Astronaut Bruce McCandless II, one of two STS-41B mission specialists participating in a historic spacewalk, is a few meters away from the cabin of the Earth-orbiting space shuttle Challenger in this 70mm frame on Feb. 7, 1984. This @science spacewalk represented the first use of a nitrogen-propelled, hand-controlled device called the Manned Maneuvering Unit (MMU), which allows for much greater mobility than that afforded previous spacewalkers who had to use restrictive tethers. Robert L. Stewart later tried out the MMU McCandless is using here, and the two of them tested another similar unit two days later. Inside the spacecraft were astronauts Vance D. Brand, commander; Robert L. Gibson, pilot; and Ronald E. McNair, mission specialist.

Owls have the widest neck rotation range among animals. This remarkable feature stems from the unique articulation of their spine with the skull. Unlike mammals, which typically have two occipital condyles (spherical ends of a bone that fit into a cavity in another bone to form a joint), owls possess only one.
Additionally, birds have a long, flexible neck containing anywhere from 11 to 23 movable vertebrae. An owl's head can swivel approximately 270 degrees in each direction, allowing for a total rotational range of one and a half full turns. This extraordinary neck flexibility is not just a peculiar trait; it's a critical adaptation that allows owls to have a nearly unobstructed view of their surroundings, an essential asset for a predator that hunts primarily at night.

Winds in Antarctica
Temperature is far from the only challenge awaiting the brave souls at the South Pole. Here blow the strongest and most persistent winds on the planet, reaching speeds of 322 km/h (with an average of about 240 km/h)! Moreover, these winds blow almost year-round, hardly ever subsiding. Nowhere else in the world will you encounter such harsh weather conditions.
However, it’s almost always sunny here: due to the cold, the air is very dry (it has the lowest relative humidity on the planet), making this place have the most intense solar radiation on Earth.
