Daily briefing: These rappelling robots autonomously explore underground tunnels
"Researchers have developed a team of robots that can autonomously explore underground tunnels. A probe maps the interior, while rovers abseil down to explore environments."
"Up to 6% of birds studied were found to be 'sex-reversed'. Most were genetically female with male reproductive organs, including one genetically male bird that laid an egg."
"A new device levitates using sunlight, with a transparent top layer allowing sunlight to pass through and a bottom layer that absorbs it for lift."
"Western Europe saw its highest average temperatures for mid-June to early July in decades, marking the hottest June on record."
A trio of robots has been developed to autonomously navigate underground lava tubes, utilizing a probe to map interiors before rappelling into caves for exploration. Additionally, a study on birds has revealed a notable occurrence of 'sex reversal,' with 6% of observed individuals showing mismatched genetic and reproductive traits. Furthermore, a novel levitation device harnesses sunlight for lift. Western Europe recorded unprecedented temperatures during mid-June to early July, marking significant climate observations.
