A research team has found a simple way to fix defects in atomically thin monolayer semiconductors. The development could open doors to transparent LED displays, ultra-high efficiency solar cells, photo detectors and nanoscale transistors.
Explaining the complex structure of tropical forests is one of the great challenges in ecology. An issue of special interest is the distribution of different sizes of trees, something which is of particular relevance for biomass estimates. A team of modellers has now developed a new method that can be used to explain the tree size distribution in natural forests. To do so, the scientists use principles from stochastic geometry. Using this approach, it is possible to assess the structure of natural forests across the world more quickly, and produce more accurate biomass estimates.
A robot in the “Spencer” project is now all set to face the real world at the major international airport Schiphol in Amsterdam. Its mission: to help passengers find their way around the airport.
A study brings the idea of the lucky streak back to the attention of the research community, offering sound mathematical proof in its favor.
A robotic bartender has to do something unusual for a machine: It has to learn to ignore some data and focus on social signals. Researchers recently investigated how a robotic bartender can understand human communication and serve drinks socially appropriately.
A mathematics student has worked out the secrets of how chocolate behaves in a chocolate fountain, answering the age-old question of why the falling 'curtain' of chocolate surprisingly pulls inwards rather than going straight downwards.
Mathematical models can provide useful clues about the impact of surgery on metastasis, and may help to predict the risk of cancer spread, scientists report. The scientists generated a mathematical model using the key parameters of primary tumor size and metastatic spread based on data generated from laboratory models designed to mimic cancer's progression in humans. They used tumor cells engineered to express a luminescent marker, allowing for the tracking and quantification of these otherwise-undetectable cancer cells.
A remarkably detailed animation of the movement of the densest and coldest water in the world around Antarctica has been produced using data generated on Australia's most powerful supercomputer, Raijin.
Vivid holographic images and text can now be produced by means of an ordinary inkjet printer. This new method is expected to significantly reduce the cost and time needed to create the so-called rainbow holograms, commonly used for security purposes -- to protect valuable items, such as credit cards and paper currency, from piracy and falsification.
Scientists investigated the advantages and perceptions of pair programming from the programmer’s standpoint.
Taking inspiration from water beetles and other swimming insects, academics have developed the Row-bot, a robot that thrives in dirty water. The Row-bot mimics the way that the water boatman moves and the way that it feeds on rich organic matter in the dirty water it swims in.
Supercomputing simulations could change how researchers understand the internal motions of proteins that play functional, structural and regulatory roles in all living organisms, say scientists in a new report.
An analysis of the tone of voice used by couples during therapy allowed a computer algorithm to predict whether a relationship would improve. In fact, the algorithm did a better job of predicting marital success of couples with serious marital issues than descriptions of the therapy sessions provided by relationship experts.
Imagine computers being able to understand paintings or paint abstract images much like humans. Now a researcher demonstrates a breakthrough concept in the field of computer vision using curves and lines to represent image shapes and furthermore to recognize objects.
Using their state-of-the-art simulation facility, scientists are exploring the use of car driving simulators as tools for training and testing drivers in order to reduce road traffic accidents and fatalities.
A new tool can detect the sex and age range of the authors behind posts and other comments on social networks. Potential applications include its use in delinquent profiling and detection of pedophile cases. It is also a valuable tool for companies, offering a window onto their customer base and informing more focused marketing actions.
A mathematical model has been developed to forecast metastatic breast cancer survival rates using techniques usually reserved for weather prediction, financial forecasting and surfing the Web.
The future of bio-inspired engineering or robotics will greatly benefit from lessons learned from plants, according to a group of researchers. They will share details about how studying plants enabled them to create tiny robots powered exclusively by changes in humidity.
Researchers have demonstrated that macroscopic entanglement can be generated at room temperature and in a small magnetic field.
Researchers have created analog and digital electronics circuits inside living plants. The scientists have used the vascular system of living roses to build key components of electronic circuits.
