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 ...

Light-responsive top layer of plastic film induces movement

Azobenzene-containing plastic film is a peculiar material: Its surface can change shape when exposed to light, making it a valuable component in modern technologies/devices like TV screens and solar cells. Scientists now ...

Ripple effects after slow-motion bubble collapse

A recent feature cover photo on Science portrayed a bubble in mid-collapse, based on a study conducted by Alexandros T. Oratis et al. The research team in mechanical engineering, mathematics and aerospace engineering at Boston ...

Scientists tap novel technologies to see water as never before

From the creation of a single droplet to the flow of a river and the world's hydrological cycle—how water binds together, and to different surfaces, has far-reaching consequences. Examining water through a new lens, a group ...

Discovery will allow more sophisticated work at nanoscale

The movement of fluids through small capillaries and channels is crucial for processes ranging from blood flow through the brain to power generation and electronic cooling systems, but that movement often stops when the channel ...

Controlling streams of liquid metal at room temperature

Researchers from North Carolina State University have demonstrated a technique that allows them to produce streams of liquid metal at room temperature. By applying a low voltage to the liquid metal, the researchers were able ...
