Like fingerprints, no 3D printer is exactly the same. That's the takeaway from a new 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.

How to create nanocages, i.e., robust and stable objects with regular voids and tunable properties? Short segments of DNA molecules are perfect candidates for the controllable design of novel complex structures. Physicists investigated methodologies to synthesize DNA-based dendrimers in the lab and to predict their behavior using detailed computer simulations.

Researchers have developed a new method -- 'Pixel Approximate Entropy' -- that measures the complexity of a data visualization and can be used to develop easier to read visualizations. 'In fast-paced settings, it is important to know if the visualization is going to be so complex that the signals may be obscured. The ability to quantify complexity is the first step towards automatically doing something about this.'

Flares from the youngest red dwarfs surveyed are 100 to 1,000 times more energetic than when the stars are older. This younger age is when terrestrial planets are forming around their stars.

Scientists have shed light on the evolutionary history of a soil-borne bacteria that is so dangerous to grazing animals it is kept behind lock-and-key to prevent its spread.

Quantum computers promise to revolutionize the future of computing. Scientists 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.

Scientists have reported unprecedented performance results for a supercapacitor electrode. The researchers fabricated electrodes using a printable graphene aerogel to build a porous three-dimensional scaffold loaded with pseudocapacitive material. In laboratory tests, the novel electrodes achieved the highest areal capacitance (electric charge stored per unit of electrode surface area) ever reported for a supercapacitor.
