Welcome to this week's edition of Science Saturday, where we explore the latest breakthroughs and discoveries shaping our world. From innovative prosthetic technology to celestial events and ecological studies, here's what's new in science.
Brain-Controlled Bionic Limbs
Researchers have reported in Natural Medicine a groundbreaking technique that enables users' brains to control bionic prostheses. The method, known as magneto micrometry, involves placing magnetic spheres inside muscles. By monitoring their movement with magnetometers, scientists can reconstruct muscle pairs, giving users a sense of the position and movement of a bionic limb.
This system is expected to be commercially available within five years. For individuals with below-knee amputations, this development promises a more natural walking experience and improved ability to navigate slopes, stairs, and obstacles.
Easter Island's 'Ring of Fire'
On October 2, the remote island of Rapa Nui, also known as Easter Island, witnessed a spectacular \"ring of fire\" annular solar eclipse. For approximately six minutes, the new moon appeared to sit perfectly inside the sun's disk. The edges of the moon touched the inside edge of the sun, creating the stunning light phenomenon known as \"Baily’s beads\".
This rare event marked the first annular solar eclipse visible from Rapa Nui since 1788, offering a unique experience for the island's residents and visitors.
Sea Urchins vs. Predators
Kelp forests off Australia's New South Wales coast are under threat from invasive sea urchins devouring them at an alarming rate. While lobsters have been considered the key predator controlling sea urchin populations, scientists from the University of Newcastle have been closely monitoring the relationship between the two species.
The latest research indicates that sharks, not lobsters, are primarily responsible for preying on sea urchins placed outside lobster dens. This discovery suggests that predator diversity is crucial for protecting kelp forests, highlighting the importance of a balanced marine ecosystem.
Flu Shot Protection
Have you received your flu shot yet? Recent data from the Centers for Disease Control and Prevention indicates that this year's vaccine lowers the chance of hospitalization by 35 percent among high-risk groups. The data was collected from over 11,000 individuals with a high risk of severe flu infections across five countries in the Southern Hemisphere.
The study found that the risk of hospitalization varied among different age groups. Insights from the Southern Hemisphere may help estimate the levels of protection for populations in the Northern Hemisphere as flu season approaches.
