Australian fossil reveals new plant species
Fresh examination of an Australian fossil -- believed to be among the earliest plants on Earth -- has revealed evidence of a new plant species that existed in Australia more than 359 Million years ago.

Cattle vs. hippopotamus: Dung in rivers of the Savannah
In many regions of the world, populations of large mammalian herbivores have been displaced by cattle breeding, for example in Kenya the hippos by large herds of cattle. This can change aquatic ecosystems due to significant differences in the amount and type of dung input. Researchers from the University of Eldoret in Kenya, the University of Innsbruck and the Leibniz-IGB have therefore taken a closer look at the dung of hippopotamus and cattle.

The smallest motor in the world
A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor is that it moves exactly at the boundary between classical motion and quantum tunneling -- and has revealed puzzling phenomena to researchers in the quantum realm.

What do 'Bohemian Rhapsody,' 'Macbeth,' and a list of Facebook friends all have in common?
A new study shows how vastly complex communication networks can efficiently convey large amounts of information to the human brain. Researcher found that works of literature, musical pieces, and social networks have a similar underlying structure that allows them to share information rapidly and effectively.
