Coming to a monitor near you: A defect-free, molecule-thick film

Thu, 11/26/2015 - 21:50
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.

Using sphere packing models to explain the structure of forests

Thu, 11/26/2015 - 15:42
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.

Robot to help passengers find their way at airport

Thu, 11/26/2015 - 15:42
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.

Mathematical proof for hot hand shooting in basketball

Thu, 11/26/2015 - 15:40
A study brings the idea of the lucky streak back to the attention of the research community, offering sound mathematical proof in its favor.

Why bartenders have to ignore some signals

Wed, 11/25/2015 - 13:39
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.

Exploring the physics of a chocolate fountain

Wed, 11/25/2015 - 01:43
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 modeling can help predict impact of surgery on cancer metastasis

Tue, 11/24/2015 - 17:26
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.

Big data reveals glorious animation of bottom water

Tue, 11/24/2015 - 17:20
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.

Inkjet hologram printing now possible

Tue, 11/24/2015 - 16:28
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.

Computer programming: Are two heads really better than one?

Tue, 11/24/2015 - 13:24
Scientists investigated the advantages and perceptions of pair programming from the programmer’s standpoint.

A row-bot that loves dirty water

Tue, 11/24/2015 - 01:28
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.

New supercomputer simulations enhance understanding of protein motion, function

Tue, 11/24/2015 - 01:23
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.

Words can deceive, but tone of voice cannot

Tue, 11/24/2015 - 01:23
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.

Computers can perceive image curves like artists

Mon, 11/23/2015 - 15:34
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.

Brains behind the wheel: Could virtual reality teach us to avoid real life accidents

Mon, 11/23/2015 - 15:33
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.

Show me how you write on social media and I'll tell you your age and sex

Mon, 11/23/2015 - 15:30
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.
