The limiting steps in molecular replacement are finding the correct location of the starting model in the unit cell and the interpretation of electron density maps produced using the imperfect phase ...

In macromolecular crystallography, the rigorous detection of changed states (for example, ligand binding) is difficult unless signal is strong. Ambiguous (‘weak’ or ‘noisy’) density is experimentally ...

Facebook's quest to get the world online is paying some unexpected dividends. Its Connectivity Lab is using image recognition technology to create population density maps that are much more accurate ...

It’s probably fair to say that Facebook hasn’t had a banner year when it comes to good publicity. What just a few years ago seemed like a benevolent and cool tech giant is often now cast in a negative ...

The North Carolina Wildlife Resources Commission has completed its deer and turkey density maps. These maps are compiled every five years to enable biologists, hunters and land-managers see areas of ...

Determining the population of crammed megacities can be difficult, but a series of population spike maps have made the task much clearer. These maps visualise population density as spikes, with the ...

TAIPEI (Taiwan News) — Earlier this month, Terence K. Teo posted this three-dimensional map of Taiwan on Twitter, which visually represents densely populated areas with peaks. Although in the original ...
