A team of engineers has proven -- with the highest score ever obtained -- that a quantum version of computer code can be written, and manipulated, using two quantum bits in a silicon microchip. The advance removes lingering doubts that such operations can be made reliably enough to allow powerful quantum computers to become a reality.
Pioneering new research could pave the way for miniaturized optical circuits and increased internet speeds, by helping accelerate the 'graphene revolution'.
Taking genetic engineering to the next level, researchers are creating modular, programmable genetic circuits that control specific plant functions.
For the first time in the world, using the newly installed 'Plasma Simulator' researchers have simulated deuterium plasma turbulence in the Large Helical Device. From this result, we have clarified that the energy confinement in a deuterium plasma is improved in comparison to a hydrogen plasma.
As the adoption of online information and location-aware technologies grows, more and more data will become available for research purposes. Data collected by volunteers or citizen scientists is a valuable source to analyse geographic phenomena such as the impact of climate change on plant and animal biological cycles. But only if the data can be evaluated on its quality. Researchers have found a way to study the quality of volunteered data efficiently so as to make it useful for scientists.
New research using advanced computer modeling sheds light on how behaviors may become 'contagious' in large groups, showing that the memory of one individual can indirectly influence that of another via shared social connections.
Tasting food relies on food volatiles moving from the back of the mouth to the nasal cavity, but researchers have wondered why airflow doesn't carry them in the other direction, into the lungs. Now a team of engineers, using a 3-D printed model of the human airway from nostril to trachea, has determined that the shape of the airway preferentially transfers volatiles to the nasal cavity and allows humans to enjoy the smell of good food.
What can you tell about people and their situations from only 140 characters? Quite a lot according to a new study about Twitter. To date, no research has tapped the vast data from social media to study situations. Using more than 20 million tweets, researchers provide insights about the psychological experience of a typical workday or week, and reveal the psychological characteristics of real-world situations that people actually experienced over the course of two weeks.
A shortage of a rare mineral could spur global market instabilities, according to a new analysis of international commodity trade networks.
As smartphones become people's primary computers and their primary cameras, there is growing demand for mobile versions of image-processing applications.
To uncover what plants honey bees rely on, researchers are applying DNA metabarcoding to pollen analysis. A new method uses three loci to characterize pollen samples collected by honey bees. This multi-locus metabarcoding approach could serve as a valuable tool for research on the native bee species that comprise local bee communities, and teach us how to enhance landscapes to sustain robust honey bee populations.
The Internet of Things, IoT, the cloud, big data...buzzwords for the modern age. But, asks one researcher: Is the IoT actually anything new and how does it work? Scientists now offer some answers and a high-level view of the IoT from the perspective of its architecture.
Three in five Australians have been the target of online harassment and abuse, new research reveals. Women and young adults are most likely to report being sexually harassed online, while one in 10 adults said someone had shared a nude or semi-nude image of them without their consent.
Researchers have cracked the code to ultra-secure telecommunications of the future in an international research project that could also expedite the advent of quantum computing.
Aso-called contrarian investment funds far outperform their herd-fund rivals in several performance measurements, new research shows, adding that their managers have found ways to gather information that other managers haven't figured out.
A new report builds on recent experimental work being carried out in gene drive using mathematical models to estimate how quickly such gene replacement can spread through a population, finding that genes can be fixed in a population quite quickly.
Researchers have programmed IBM's Watson so that it can have a real-time, Q&A conversation about ways to creatively solve problems in a wide-variety of professions. It's similar to a Google search, but without getting multiple, potentially-related links. This new interactive system allows Watson to give answers in paragraph form.
A new framework could help future scientists improve their understanding of all types of networks, from social media channels to beehives. The work included over 30 network science researchers, educators, teachers and students to set up a framework that any school can adapt to teach students the concept of a network from the ground up.
An increasing amount of drugs taken by humans and animals make it into streams and waterways, and pharmaceutical pollution has had catastrophic ecosystem consequences despite low levels of concentration in the environment. The effect of pharmaceuticals and other contaminants of emerging concern on the environment has been the focus of recent research.
Computer assisted cognitive behavioral therapy is likely to be ineffective in the treatment of depression because of low patient adherence and engagement, suggests the largest study of its kind.
