Ultralight material withstands supersonic microparticle impacts

A new study by engineers at MIT, Caltech, and ETH Zürich shows that "nanoarchitected" materials—materials designed from precisely patterned nanoscale structures—may be a promising route to lightweight armor, protective ...

Solving a puzzle to design larger proteins

A team from Japan and the United States has identified the design principles for creating large 'ideal' proteins from scratch, paving the way for the design of proteins with new biochemical functions. Their results appear ...

Lighting the way to folding next-level origami

Origami may sound more like art than science, but a complex folding pathway that proteins use to determine their shape has been harnessed by molecular biologists, enabling them to build some of the most complex synthetic ...

The optimal design of cellular sensing systems

To survive and prosper, living cells continually respond and adapt to changes in their environment. To this end, they have developed sensing systems that rival the best man-made sensing devices. Yet, how accurately these ...

How insects activate muscles to adapt to limbs removed

Adaptability explains why insects spread so widely and why they are the most abundant animal group on earth. Insects exhibit resilient and flexible locomotion, even with drastic changes in their body structure such as losing ...

The wily octopus: King of flexibility

Octopuses have the most flexible appendages known in nature, according to a new study in Scientific Reports. In addition to being soft and strong, each of the animal's eight arms can bend, twist, elongate and shorten in many ...

Mechanisms responsible for tissue growth

In adult tissue, the number of cells in tissues and organs remains constant, and any new cells produced by cell division need to be compensated by the loss of other cells. In contrast, during postnatal growth, an excess of ...
