Ancient artists used a technique called stippling – in which pictures are created by painting or carving a series of tiny dots – to produce drawings on cave walls and utensils thousands of years ago.
This image of a human cranium was created with a new kind of computer-imaging software that uses the ancient technique of stippling to convert complex medical data into 3-D images that can be quickly viewed by medical professionals. Data from CT scans were converted into dots to create the stippled image. Cave dwellers and artisans used stippling thousands of years ago to create figures by painting or carving a series of tiny dots. More recently, 19th century Parisian artist Georges Seurat used the method, also called pointillism, to draw colorful, intricately detailed works. Because dots are the most simple visual element in a picture, they also are ideal for computer visualizations. (Purdue University School of Electrical and Computer Engineering)

Now engineers at Purdue University have created a new kind of computer-imaging software that uses stippling to quickly produce complex pictures of internal organs and other renderings. The method is 10 times faster than some conventional methods and could provide a tool for medical professionals to quickly preview images in real time as a patient is being examined with imaging technologies such as CT scans and magnetic resonance imaging (MRI).
In stippling, also known as pointillism, the artist creates numerous dots with paint, ink or pencil to produce gradations of light and shade, forming an image. Georges Seurat, a 19th century Parisian artist, used the same technique to draw colorful, intricately detailed works.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
