For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.

An international research team has taken a decisive step toward a new generation of atomic clocks. The researchers have created a much more precise pulse generator based on the element scandium, which enables an accuracy of one second in 300 billion years -- that is about a thousand times more precise than the current standard atomic clock based on caesium.

Materials are often considered to be one phase, but many engineering materials contain two or more phases, improving their properties and performance. These two-phase materials have inclusions, called precipitates, embedded in the microstructure. Alloys, a combination of two or more types of metals, are used in many applications, like turbines for jet engines and light-weight alloys for automotive applications, because they have very good mechanical properties due to those embedded precipitates. The average precipitate size, however, tends to increase over time-in a process called coarsening-which results in a degradation of performance for microstructures with nanoscale precipitates.

A team has used neutron crystallography to image all of the atoms in a radical intermediate of a copper amine oxidase enzyme. They disclosed previously unknown details, such as precise conformational changes, that help to explain the enzyme's biochemistry. This work might help researchers engineer enzymes that facilitate unusual chemistry or are highly efficient at room temperature that are useful in chemical industry.
