The calculations show that these weak magnetic fields were present throughout the entire plasma volume, with strengths as low as 10^-20 Tesla.

Bonobos will share with strangers before acquaintances

Researchers found that bonobos will share food with a stranger before an acquaintance in a series of experiments. In most cases, the test subject chose to release the stranger first, even when there was no social interaction afterwards. This behavior contrasts with chimpanzees and highlights the unique social dynamics of bonobos.

Dance of water molecules turns fire-colored beetles into antifreeze artists

Researchers found that fire-colored beetle antifreeze proteins protect against freezing temperatures through a combination of direct interaction with ice crystals and interactions via water molecules. This process, previously thought to occur only locally, also happens over longer distances due to the dynamics of water molecules.

ALMA shows how young star and planets grow simultaneously

Astronomers have discovered that planets forming around a young star are helping the star continue to grow by clearing gaps in its surrounding disk.
