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. Biologi…

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 …

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 p…

A paper battery with water switch

A team of researchers has developed a water-activated disposable paper battery. The researchers suggest that it could be used to power a wide range of low-power, single-use disposable electronics — such as smart labels for tracking objects, environmen…
