Tiny crab robots are so small they can walk on top of a US penny
Yet at its most elusive, hope still resides within the human spirit — a force that is capable of growth and change.
It’s the same perpetual motion that has propelled innovation on our planet for thousands of years and made the impossible possible.
It’s inspiring to think of what we’re capable of when we work together, and “we all shine on, like the moon and the stars and the sun.”
If you tried to play a game of “I Spy” with these robots, you might lose.
The world’s smallest remote-controlled walking robots are more miniscule than the thickness of a United States penny.
These little critter bots are still in development, but the researchers envision a future that could include minimally invasive surgeries or even flight.
Dinosaurs like the towering T. rex and lumbering Brachiosaurus were hot-blooded (and scientists checked it to see).
Early on, paleontologists grouped dinosaurs with reptiles, which are cold-blooded. But modern researchers have come to the consensus that dinos were much more like birds.
Now, a groundbreaking study has found some dinosaurs were warm-blooded like birds and mammals. So what’s the difference? Warm-blooded animals require lots of oxygen and calories to maintain their body temperature, while cold-blooded animals breathe and eat less.
A long time ago
Archaeologists have uncovered 134 previously unknown Iron Age settlements during a survey of the region north of Hadrian’s Wall in the United Kingdom.
Much is known about the Roman quest for control, but written sources from the time period, and perspectives of the locals, are scarce. Just what did Indigenous people think about these invaders as they tried to push into modern-day Scotland?
A new project called “Beyond Walls” aims to shed light on who lived at these settlements and their relationship with the well-armed Roman legions, who were never quite able to control northern Britain.
Across the universe
The Hubble Space Telescope has helped astronomers make great strides in unlocking the secrets of the universe.
One of the main goals for the observatory when it launched was to measure the expansion rate of the universe. Hubble data has allowed scientists to discover and refine that accelerating rate. But in the process, they have stumbled upon an unusual wrinkle.
The Indian rhinoceros, once on the verge of extinction, is rebounding in a big way.
The governments of India and Nepal have also worked on conservation efforts to protect the vulnerable animals from poaching and provide them with room to roam.
The Indian rhino is poised to be a comeback kid, but experts say there is still work to be done.
