Computer-created Bacterial Genome is World First
Scientists have developed a new method that greatly simplifies the production of large DNA molecules containing many hundreds of genes. With this method, they have built the first genome of a bacterium entirely designed by a computer algorithm. The method has the potential to revolutionise biotechnology.

Supercomputers Help Supercharge Jellyfish Proteins
Using supercomputers, scientists are designing proteins that self-assemble to combine and resemble life-giving molecules like hemoglobin. The scientists say their methods could be applied to useful technologies such as pharmaceutical targeting and artificial energy harvesting. Using jellyfish proteins, the scientists were able to assemble a complex sixteen protein structure composed of two stacked octamers.

What Big Data Reveals About the Diversity of Species
"Big data" and large-scale analyses are critical for biodiversity research. The necessary data may come from many sources: museum collections, biological literature, and local databases. Researchers have investigated how this wealth of knowledge can best be integrated so that it can be transported into the digital age and used for research.

A Compass Pointing West
Researchers at the Paul Scherrer Institute PSI and ETH Zurich have discovered a special phenomenon of magnetism in the nano range. It enables magnets to be assembled in unusual configurations. This could be used to build computer memories and switches to increase the performance of microprocessors. The results of the work have now been published in the journal Science.

What’s in This Plant? Automated System Helps Find Potential Drugs
Researchers have developed a new computational mass-spectrometry system for identifying metabolomes (entire sets of metabolites for different living organisms). When the new method was tested on select tissues from 12 plants species, it was able to note over a thousand metabolites. Among them were dozens that had never been found before, including those with antibiotic and anti-cancer potential.

App Designed to Predict and Prevent Diet Cheats
When the algorithm detects the risk of lapsing is high, it sends a special coaching message that matches the reasons that someone is at risk. The predictions get better over time as the app learns a user's behavioral patterns.
