Phys.org / Why doesn't Venus have a moon? A new study may have the answer

Venus is one of the solar system's most unusual planets. It may sometimes be called "Earth's twin" because of its similar size and density, but it rotates on its axis in the opposite direction of most planets, has surface ...

Phys.org / Salt may have helped turn Earth into a frozen world 700 million years ago

Earth may have been pushed deeper into a global deep freeze by something surprisingly ordinary: salt. Around 700 million years ago, Earth entered periods of extreme glaciation known as Snowball Earth, when ice is thought ...

Phys.org / The biggest black hole merger ever observed could be less massive than it appears

Gravitational waves are ripples in spacetime created when pairs of black holes spiral into each other and eventually merge. But if this ripple has been warped by another massive object on its way to Earth, a new analysis ...

Phys.org / Completing the connectome: How pursuing a map of the fly brain rewired neuroscience

When researchers at HHMI's Janelia Research Campus set out to create a map of all the neurons in the fruit fly brain in 2008, many in the scientific community thought they were out of their minds.

Phys.org / Heat has a memory—and a new theoretical framework can track it

Heat, it turns out, has a memory. A cooling cup of coffee may not seem particularly thoughtful. At the scale of a kitchen, heat appears to follow a straightforward rule: it moves from warmer places to cooler ones. Leave the ...

Phys.org / How stressed cells put the brakes on protein 'shipping'

Cells synthesize proteins in the endoplasmic reticulum (ER), and these proteins are transported to the Golgi apparatus for distribution to their ultimate destinations inside and outside the cell. The structures that transport ...
