Nature, the master engineer, is coming to our rescue again. Inspired by scorpions, scientists have created new pressure sensors that are both highly sensitive and able to work across a wide variety of pressures.

Pressure sensors are key components in an array of applications, from medical devices and industrial control systems to robotics and human-machine interfaces. Silicon-based piezoresistive sensors are among the most common types used today, but they have a significant limitation. They can’t be super sensitive to changes and work well across a range of pressures at the same time...

To see the world in a grain of sand: Investigating megaripples at Kerrlaguna on Mars

On Mars, the past is written in stone—but the present is written in sand. Last week, Perseverance explored inactive megaripples to learn more about the wind-driven processes that are reshaping the Martian landscape every day.

After wrapping up its investigation at the contact between clay a...

A new Durham University study has found that a giant impact may not be responsible for the formation of Jupiter’s remarkable “dilute” core, challenging a theory about the planet’s history.

Jupiter, the largest planet in our solar system, has a mystery at its heart. Unlike what scientists once expected, its core doesn’t have a sharp boundary but instead gradually blends into the surrounding layers of mostly hydrogen (a structure known as a dilute core).

How this dilute core formed has been a key question among scientists and astronomers ever since NASA’s Juno spacecraft first revealed its existence.

A previous study suggested that a colossal collision with an early planet containing half of Jupiter’s core material could have thoroughly ...
