This century, our world will be flooded with hundreds of billions of smartphones, gadgets, sensors and other smart objects connected to the internet. New research is at the forefront of efforts to redesign the internet to handle the enormous increase in traffic.
Creating a 3-D replica of someone's hand complete with all five fingerprints and breaking into a secure vault sounds like a plot from a James Bond movie. But researchers recently discovered this may not be as far-fetched as once thought and wants security companies and the public to be aware.
Scientists have demonstrated a highly efficient method for wirelessly transferring power to a drone while it is flying. The breakthrough could in theory allow flying drones to stay airborne indefinitely -- simply hovering over a ground support vehicle to recharge -- opening up new potential industrial applications.
Engineers have created a new quantum bit that remains in a stable superposition for 10 times longer than previously achieved, dramatically expanding the number of calculations that could be performed in a future silicon quantum computer.
When a truck rumbles by a building, vibrations can travel up to the structure's roof and down again, generating transient tremors through the intervening floors and beams. Now researchers have developed a computational model that makes sense of such ambient vibrations, picking out key features in the noise that give indications of a building's stability. The model may be used to monitor a building over time for signs of damage or mechanical stress.
A new extensible wiring technique capable of controlling superconducting quantum bits has now been developed, representing a significant step towards to the realization of a scalable quantum computer.
A study of 20 major cloud hosting services has found that as many as 10 percent of the repositories hosted by them had been compromised -- with several hundred of the "buckets" actively providing malware. Such bad content could be challenging to find, however, because it can be rapidly assembled from stored components that individually may not appear to be malicious.
What you tweet says a lot about your politics and who you are going to vote for in this highly volatile presidential election, according to TweetCast, an online tool developed by Northwestern University computer scientists. The algorithm, trained on Twitter users, can predict whether citizens will vote for Donald Trump or Hillary Clinton. Perhaps more surprising, the tool also predicts which states will go blue or red (Democrat or Republican).
A research team has described a novel tabletop display system that allows multiple viewers to simultaneously view a hologram showing a full 3-D image as they walk around the tabletop, giving complete 360-degree access.
Researchers have developed a low-cost, portable laboratory on a smartphone that can analyze several samples at once to catch a cancer biomarker, producing lab quality results.
If you type on your desktop or laptop computer's keyboard while participating in a Skype call, you could be vulnerable to electronic eavesdropping, according to researchers.
A new English study on the link between cyber-bullying and suicide has found that ten per cent of children are involved in cyber-bullying, as victims, perpetrators or both, and that they are much more likely to view web content containing self-harm and suicide. It calls for more web-based prevention and intervention strategies to tackle the issue.
Virtual Reality can get the elderly in nursing homes to be happier about exercising. A new research project shows that the technology motivates older people in nursing homes to get moving.
A revolutionary, light-activated semiconductor nanocomposite material has been created that can be used in a variety of applications, including microscopic actuators and grippers for surgical robots, light-powered micro-mirrors for optical telecommunications systems, and more efficient solar cells and photodetectors.
Tiny robots have been helping researchers study how climate change affects biodiversity. These “robomussels” have the shape, size, and color of actual mussels, with miniature built-??in sensors that track temperatures inside the mussel beds.
Young people decide whether they've had enough to drink the same way the cruise control on a car "decides" whether to accelerate or hit the brakes, explains a unique research project that aims to analyze drinking behavior the way engineers might analyze a mechanical system.
A new study mathematically explains how tumors induce the growth of blood vessels. The study maintains that the tips of the blood vessels expand like a soliton, a solitary wave similar to a tsunami.
Drones are proving to be a good means of mapping human-made changes in the landscape. Geophysicists are experimenting with drones in inaccessible areas of the Caribbean.
The most efficient quantum cascade laser ever designed have now been created by researchers who have done it in a way that makes the lasers easier to manufacture. Quantum cascade lasers, or QCLs, are tiny -- smaller than a grain of rice -- but they pack a punch. Compared to traditional lasers, QCLs offer higher power output and can be tuned to a wide range of infrared wavelengths. They can also be used at room temperature without the need for bulky cooling systems.
Thanks to new functionality, smartwatches can recognize objects and activities by monitoring vibrations that occur when people hold objects or use tools. This new technology could even be used to help tune a guitar, say developers.
