Hubble images a complex galactic trio

This luminescent image features multiple galaxies, perhaps most noticeably LEDA 58109, the lone galaxy in the upper right. LEDA 58109 is flanked by two further galactic objects to its lower left—a galaxy with an active galactic nucleus (AGN) called SDSS J162558.14+435746.4 that partially obscures the galaxy SDSS J162557.25+435743.5, which appears to poke out to the right behind the AGN.

Swimming without brains and muscles

Bacteria and other unicellular organisms developed sophisticated ways to actively navigate their way, despite being comparably simple structures. To reveal these mechanisms, researchers used oil droplets as a model for biological microswimmers. Biologists investigated the navigation strategies of microswimmers in several studies: how they navigate against the current in narrow channels, how they...

Communication makes hunting easier for chimpanzees

Similar to humans, chimpanzees use communication to coordinate their cooperative behavior -- such as during hunting. When chimpanzees produce a specific vocalization, known as the 'hunting bark', they recruit more group members to the hunt and capture their prey more effectively, researchers have now shown.

Space travel: Bone aging in fast forward

Long periods in space damage bone structure irreparably in some cases and can make parts of the human skeleton age prematurely by up to 10 years, according to new research. Adapted training programs in conjunction with medication could provide better protection for astronauts on future space missions. The research findings also have implications for treating rheumatic conditions in clinical...

Technique for the isolation of volatile food compounds optimized

A research team has succeeded in automating an established method for the gentle, artifact-avoiding isolation of volatile food ingredients. As the team's current comparative study now shows, automated solvent-assisted flavor evaporation (aSAFE) offers significant advantages over the manual process. It achieves higher yields on average and reduces the risk of contamination by nonvolatile...
