On any given day, tens of thousands of biologists around the globe run DNA sequences of unknown function through a lightning-fast online algorithm called BLAST – typically submitting 200 to 400 base pairs, or "letters" of genetic code, to be matched against the billions of letters for known genes. Searching for similarities that can shed light on functional or evolutionary relationships, scientists routinely use BLAST to churn through and produce vast amounts of data. Everyday applications include genetic medicine and pharmaceuticals. Yet this process and, more generally, genomics remain dimly understood by the public.

"Ecce Homology," an interactive "bioart" installation to be showcased at SIGGRAPH 2005 – in Los Angeles, July 31 through Aug. 4 – quite literally makes BLAST and genomics visible.
Headed up by new-media artist Ruth West – director of visual analytics and interactive technologies at the University of California, San Diego National Center for Microscopy and Imaging Research and research associate with the UCSD Center for Research and Computing in the Arts – the "Ecce Homology" project is an ongoing collaboration among 11 biologists, artists and computer scientists from UCSD, UCLA and the University of Southern California.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
