Self-generating yarn made from graphene oxide strands

A team of researchers from Zhejiang University, Xi'an Jiaotong University and Monash University has developed a way to bind multiple strands of graphene oxide into a thick cable. In their paper published in the journal Science, ...

Ancient ammonoids' shell designs may have aided buoyancy control

Ammonoids, ancestors of today's octopus, squid and cuttlefish, bobbed and jetted their way through the oceans for around 340 million years beginning long before the age of the dinosaurs. If you look at the fossil shells of ...

Direct 2D-to-3D transformation of pen drawings

Pen drawings can allow simple, inexpensive and intuitive two-dimensional (2D) fabrication. Materials scientists aim to integrate such pen drawings to develop 3D objects. In a new report now published on Science Advances, ...

The mystery of pointy oil droplets

A certain type of oil droplets changes shape when cooled and shrunk: from spherical through icosahedral to flat hexagonal. Two competing theories couldn't fully explain this, but now, a Physical Review Letter by Ireth García-Aguilar ...

Nanosheet-based electronics could be one drop away

Scientists at Japan's Nagoya University and the National Institute for Materials Science have found that a simple one-drop approach is cheaper and faster for tiling functional nanosheets together in a single layer. If the ...

Math enables custom arrangements of liquid 'nesting dolls'

While the mesmerizing blobs in a classic lava lamp may appear magical, the colorful shapes move in response to temperature-induced changes in density and surface tension. This process, known as liquid-liquid phase separation, ...

Ants adapt tool use to avoid drowning

Researchers have observed black imported fire ants using sand to draw liquid food out of containers, when faced with the risk of drowning. This is the first time this sophisticated tool use has been reported in animals. These ...
