Scientists reveal the physics of Jackson Pollock's painting technique

The celebrated painter Jackson Pollock created his most iconic works not with a brush, but by pouring paint onto the canvas from above, weaving sinuous filaments of color into abstract masterpieces. A team of researchers analyzing the physics of Pollock's technique has shown that the artist had a keen understanding of a classic phenomenon in fluid dynamics—whether he was aware of it or not.

How do you know it's perfect graphene?

Scientists have discovered an indicator that reliably demonstrates a sample's high quality, and it was one that was hiding in plain sight for decades.

Researchers build a biomimetic 'soft cannon' to understand how fungal spores are dispersed

A team of researchers from the Technical University of Denmark, the University of Copenhagen and Wageningen University and Research has built a tiny biomimetic 'soft cannon' to better understand how fungal spores are dispersed. In their paper published in Journal of the Royal Society Interface, the group describes building their tiny cannon and what they learned from firing it.

LS2 Report: Linac4 knocking at the door of the PS Booster

Busy activity has returned to the CERN Control Centre (CCC), where the Operation group coordinates the current Linac4 test run, supported by the Accelerators and Beam Physics (ABP) group and all the involved equipment groups. As we write, the nominal 160 MeV beam has already reached the Linac4 dump.

Structured light promises path to faster, more secure communications

Quantum mechanics has come a long way during the past 100 years but still has a long way to go. Researchers now review the progress being made in using structured light in quantum protocols to create a larger encoding alphabet, stronger security and better resistance to noise.

Study shows ability to detect light from UV to the IR optical regimes using spin currents

The spin Seebeck effect (SSE) can be used to detect light across a broad optical range -- ultraviolet through visible to near-infrared. This has future implications on novel spin current-based technologies.

Scientists learn how to make oxygen 'perform' for them

When it comes to the fundamentals of making better materials—stronger-but-thinner glass for televisions or phone screens, for example—it almost always comes down to the building blocks of science. Understand the structure around an atom, the most basic piece of any material, and you might be able to change that material for the better.

A new type of acoustic insulation enables sound to be concentrated in corners

A group of researchers from the Universidad Carlos III de Madrid (UC3M), in collaboration with Chinese scientists from the University of Nanjing (NJU), have designed a new type of acoustic insulation that enables sound waves to be concentrated in corners. This line of research could have applications in industrial ultrasound technologies or in the improvement of certain medical diagnostic tests such as ultrasound.

First magnet installed for the ALPS II experiment at DESY

The international ALPS II ("Any light particle search") collaboration installed the first of 24 superconducting magnets today, marking the start of the installation of a unique particle physics experiment to look for dark matter. Located at the German research centre DESY in Hamburg, it is set to start taking data in 2021 by looking for dark matter particles that literally make light shine through a wall, thus providing clues to one of the biggest questions in physics today: what is the nature of dark matter?

Liquid crystal droplets as versatile microswimmers

Nature's most common swimmers are single-celled organisms such as microalgae that swim toward light sources, and sperm cells that swim toward an ovum. For a physicist, cells are simply biochemical machines, which must obey well-described laws of chemistry and physics. Can scientists therefore create life-like, swimming micro-machines without invoking biology?
