When designing flying vehicles, there are many aspects of which we can be certain but there are also many uncertainties. Most are random, and others are just not well understood. University of Illinois Professor Harry Hilton brought together several mathematical and physical theories to help look at problems in more unified ways and solve physical engineering problems.

Researchers from the Higher School of Economics and KU Leuven have developed a method of measuring growth in students' proficiency in digital learning environments. It helps to see the progress of online course participants in dynamics, i.e., to understand how students study and how the course works. The results of the study have been published in the journal Behaviour Research Methods.

Like fingerprints, no 3D printer is exactly the same. That's the takeaway from a new University at Buffalo-led study that describes what's believed to be the first accurate method for tracing a 3D-printed object to the machine it came from. The advancement could help law enforcement and intelligence agencies track the origin of 3D-printed guns, counterfeit products and other goods.

MIT researchers have developed a cryptographic system that could help neural networks identify promising drug candidates in massive pharmacological datasets, while keeping the data private. Secure computation done at such a massive scale could enable broad pooling of sensitive pharmacological data for predictive drug discovery.

A statistical method could fill the gaps in the US cancer registry data to estimate the short- and long-term risk of recurrence of hormone receptor (HR)-positive and HR-negative breast cancers.

Quantum computers promise to revolutionize the future of computing. A scientist from the Technical University of Munich (TUM) together with his colleagues from the University of Waterloo and from IBM have now demonstrated for the first time that quantum computers do indeed offer advantages over conventional computers. They developed a quantum circuit that can solve a problem that is unsolvable using any equivalent classical circuit.

The fall of Angkor has long puzzled historians, archaeologists and scientists, but now a University of Sydney research team is one step closer to discovering what led to the city's demise -- and it comes with a warning for modern urban communities.
