“The results are a major leap forward since the presence of a cosmic dark matter web that extends over such large distances has never been observed before,” says Ludovic Van Waerbeke, an assistant professor in the Dept. of Physics and Astronomy.
To glimpse the unseen structures, the team of French and Canadian scientists “X-rayed” the dark matter, an invisible web that makes up more than 80 per cent of the mass of the universe.
The team used a recently developed technique called “weak gravitational lensing,” which is similar to taking an X-ray of the body to reveal the underlying skeleton. The study relied on data gathered from the world’s largest digital camera.
“This new knowledge is crucial for us to understand the history and evolution of the cosmos,” says Van Waerbeke. “Such a tool will also enable us to glimpse a little more of the nature of dark matter.”
The astronomers observed how light from distant galaxies is bent and distorted by webs of dark matter as it travels toward Earth. They then mapped dark matter structures by measuring the distortions seen in these galaxy light patterns.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
