Scientists have created and imaged the smallest possible five-ringed structure – about 100,000 times thinner than a human hair – and you'll probably recognise its shape.

Scientists realize one of the most elementary and oldest 'gedanken' experiments in modern physics, namely, excitation of a single molecule with a single photon.

In a remarkable feat of micro-engineering, UNSW physicists have created a working transistor consisting of a single atom placed precisely in a silicon crystal.

A four wheel drive car just 1 nm long which uses electrons as fuel has been developed by researchers at the University of Groningen, who hope it might find uses in nanometre-sized robotics or as tiny transporters to move molecules around. The vehicle has an organic carbon-based frame and four wheel or rotor parts connected to the body via carbon-carbon double bonds. It navigates its copper surface when a nearby scanning tunnelling microscope fires electrons at the bonds, causing them to break and reform the other way around – causing the wheels to turn and the car to move forward.

Here, we report a synthetic DNA-based system that integrates long-range transport and information processing. We show that the path of a motor through a network of tracks containing four possible routes can be programmed using instructions that are added externally or carried by the motor itself.

Astronomers have discovered carbon atoms connected in the shape of soccer balls, kicking around the cosmos. How were they detected? And why do scientists search space for these largest of molecules?

In the beginning was the Sound. The big bang. From that event more than 13 billion years ago, science tells us, the universe rapidly expanded and cooled enough that its white noise of energy could change into subatomic particles. Those particles later joined to form atoms, and those atoms combined to form molecules, eventually leading to the emergence of life. Biochemists are researching what harmonious chemical conditions might have led to the emergence of life.

(PhysOrg.com) -- What does a proton look like? The common answer to this question is that protons are much too small to scatter light, and since light is necessary for us to see things, protons do not “look” like anything.
