Droplets emanating from a molecular 'nano-tap' would behave very differently from those from a household tap 1 million times larger -- researchers at the University of Warwick have found. This is potentially crucial step for a number of emerging nano technologies, e.g., manufacture of nano-sized drug particles, lab-on-chip devices for in situ diagnostics, and 3D printers capable of nanoscale resolution.
Researchers have developed a new AI-driven platform that can analyze how pathogens infect our cells with the precision of a trained biologist.
Sustainable heating, ventilation, and air conditioning systems, such as those that harness low-enthalpy geothermal energy, are needed to reduce collective energy use and mitigate the continued effects of a warming climate. In a paper publishing on Feb. 12 in the SIAM Journal on Applied Mathematics, Miguel Hermanns and Santiago Ibáñez use asymptotic expansion techniques to study the harmonic thermal response of vertical geothermal boreholes in such systems to sub-annual harmonic excitations.
Modern economies need courageous, entrepreneurial individuals to thrive yet the same qualities can bring greater risks according to a world-first study. QUT's Associate Professor Martin Obschonka joined forces with researchers from Germany's University of Mannheim and the University of Cambridge in the UK to study data on courage from more than 390,000 Americans. The project was a collaboration with Time Magazine which collected the data from an online Harry Potter-style sorting hat quiz publicized on its website.
By providing an over-abundance of energy to cells, diseases like obesity and diabetes might super-charge growth and cause cells to become cancerous.
Termite construction projects have no architects, engineers or foremen, and yet these centimeter-sized insects build complex, meter-sized structures all over the world. Harvard researchers demonstrate how simple rules linking environmental physics and animal behavior can give rise to these structures. Their research sheds lights on broader questions of swarm intelligence and may serve as inspiration for designing more sustainable human architecture.
Researchers at the US CCDC Army Research Laboratory, the Army's corporate research laboratory (ARL) in collaboration with the Army's Institute for Creative Technologies and Northeastern University published a paper today in the Proceedings of the National Academy of Sciences suggesting the use of autonomous machines increases cooperation among individuals.
Harvard researchers have developed a framework that explains how bees use environmental signals to collectively cluster and continuously ventilate the hive.
The so-called Abelian sandpile model has been studied by scientists for more than 30 years. Even though the sandpile model serves as the archetypical model to study self-organized criticality, questions about its characteristics are still open and remain an active field of research. Researchers at IST Austria have now discovered a new property of this mathematical model: they managed to induce dynamics in the self-similar fractal patterns reminiscent of sand dunes in the desert.
Whether the presence of a college or hospital increases a home's value has to do with the institution's size and the ZIP code's population, says a new study by computer scientists at the University of California, Riverside. Colleges and hospitals do affect home prices and rents, but not always positively. Prices also rise and fall faster around these institutions, increasing the risk for investors.
