Suddenly related
Suddenly related
Biologists rewrite "family history" of fungi You can't choose kinship. This also applies to a special group of fungi that could not be more different: Whether they grow in native forests, live in the guts of insects or are found in trees in the Amazon. Until now, they were not considered to be related to each other because of their different appearance and their dissimilar life strategies.

The theory of micro-hairs
The theory of micro-hairs
Tiny hairs on cell walls, so-called -cilia-, can move in unison to pump fluid. Now there finally is a physical theory describing these hairs' movements. They are only very simple structures, but without them we could not survive: Countless tiny hairs (cilia) are found on the outer wall of some cells, for example in our lungs or in our brain.

Faster and more Efficient Computer Chips Thanks to Germanium
Faster and more Efficient Computer Chips Thanks to Germanium
TU Wien (Vienna) has succeeded in making a new type of material usable for chip technology. This enables faster, more efficient computers and new types of quantum devices. Our current chip technology is largely based on silicon. Only in very special components a small amount of germanium is added. But there are good reasons to use higher germanium contents in the future: The compound semiconductor silicon-germanium has decisive advantages over today's silicon technology in terms of energy efficiency and achievable clock frequencies.

The Mathematics of Separate Things
By Birgit Baustädter Discrete mathematics is so much more than just "the language of computer science", as it is often referred to. But it is not "discrete" in the usual sense. Points are particularly discrete. Discrete mathematics derives from the Latin discernere, which means "to separate". "Discrete mathematics is about delimited or clearly separated objects - such as points, lines or sequences of integers," explains Oswin Aichholzer, a computer scientist at Graz University of Technology (TU Graz).
