Our Brains “See” Beams Of Motion Emanating From People’s Faces Towards The Object Of Their Attention
Back in the 1970s, the developmental psychologist Jean Piaget discovered that, if you ask young children to explain the mechanics of vision as they understand them, their answers tend to reveal the exact same misconception: that the eyes emit some sort of immaterial substance into the environment and capture the sights of objects much like a projector.

Experts Ponder Nuclear Rockets To Send Humans To Mars
When NASA's Perseverance rover touched down on the Martian surface last week, humans cheered from the confines of planet Earth. But if the space agency or others hope to leave and send astronauts to Mars, experts say they need to consider a technology that was studied decades ago but never fully developed: nuclear-powered rockets.

Dogs synchronize their behavior with children, but not as much as with adults, study finds
Dogs synchronize their behavior with the children in their family, but not as much as they do with adults, a new study from Oregon State University researchers found. The findings are important because there is a growing body of evidence that dogs can help children in many ways, including with social development, increasing physical activity, managing anxiety or as a source of attachment in the face of changing family structures, the researchers said. Yet, very little research has focused on how dogs perceive and socially engage with children.

Martian rover sends back ‘overwhelming’ video, audio from the Red Planet
Just four martian days after touching down on the Red Planet, NASA’s Perseverance rover has sent back its first video of its new home: a 1-minute arabesque of color and motion captured from four on-board cameras, as the car-size rover dangles from its rocket-propelled descent vehicle, a red-and-white parachute snaps into place, and the pitted surface of Mars comes slowly into view, dark canyons giving way to ripples of dust that look like giant, rust-colored dunes (see video, above).

Neanderthals died out after Earth's magnetic poles flipped, causing a climate crisis 42,000 years ago, a study says
Earth saw a lot of commotion when its magnetic poles flipped 42,000 years ago. Scientists have known about the flip since the late 1960s. Earth's magnetic poles aren't static - they're generated by electric currents from the planet's liquid outer core, which is constantly in motion. As of late, Earth's magnetic North pole has wandered considerably on a path toward northern Russia.

This Ferret Died 33 Years Ago. Scientists Just Brought Her Back to Life.
For the first time, scientists have cloned an endangered U.S. species: a black-footed ferret named Elizabeth Ann, whose donor has been dead for more than 30 years. After the original ferret, Willa, died in 1988, scientists froze her body to preserve her genetic material, hoping to someday perform an experiment like this.

Researchers observe stationary Hawking radiation in an analog black hole
Black holes are regions in space where gravity is very strong—so strong that nothing that enters them can escape, including light. Theoretical predictions suggest that there is a radius surrounding black holes known as the event horizon. Once something passes the event horizon, it can no longer escape a black hole, as gravity becomes stronger as it approaches its center.
