RoBoa Slinks Through Disaster Areas that are Too Perilous for Other Robots

Robotics, Science / Mauro Lucas

When disaster strikes, drones and robots can search for survivors in dangerous zones. The student team at ETH Zurich designed the RoBoa to slither through debris that would stop other robots. Developed at the Autonomous Systems Lab, RoBoa aids rescue teams in disaster and war zones. Its snake-like movement allows it to navigate rubble while

Deaf Mosquitoes Lose Mating Ability, Paving the Way for New Population Control

Biology, Science / Ngoma Manuel

Genetic research has revealed that male mosquitoes lose their ability to reproduce when they lose their sense of hearing. This surprising discovery could open new methods to reduce mosquito populations and the diseases they spread. While the high-pitched buzz of a mosquito is highly annoying to humans, especially on warm nights, it is an irresistible

Kombucha Microbes Mimic Fasting by Breaking Down Fat Stores Effortlessly

Healthcare, Medicine / Ngoma Manuel

While kombucha might not suit everyone’s taste, it could offer some benefits similar to fasting, minus the challenge of actually fasting. Researchers have found that when the yeasts and bacteria from this fermented, slightly sweetened tea colonize the gut, they can influence fat metabolism without requiring any other dietary adjustments, leading to reduced fat storage.
