The key to private and efficient data storage

Sun, 04/30/2017 - 01:25
Cloud storage services, like Dropbox and Gmail, may soon be able to better manage your content, giving you more storage capacity while still being unable to ‘read’ your data.

PowerPoint, LED projector enable new technique for self-folding origami

Sat, 04/29/2017 - 13:50
A new use for the ubiquitous PowerPoint slide has now been discovered: Producing self-folding three-dimensional origami structures from photocurable liquid polymers.

Mapping the edge of reality

Fri, 04/28/2017 - 19:45
A genetic algorithm has been determined to confirm the rejection of classical notions of causality.

Hybrid circuits can increase computational power of chaos-based systems

Fri, 04/28/2017 - 19:45
Combining digital and analog components in nonlinear, chaos-based integrated circuits can improve their computational power by enabling processing of a larger number of inputs, new research shows.

Ultracold atom waves may shed light on rogue ocean killers

Fri, 04/28/2017 - 19:45
By precisely controlling the quantum behavior of an ultracold atomic gas, physicists have created a model system for studying the wave phenomenon that may bring about rogue waves in Earth's oceans.

No, complex is not complicated -- it is rather simple

Fri, 04/28/2017 - 13:39
The simplest experimental system to date to identify the minimum requirements for the emergence of complexity has been developed.

Artificial intelligence shows potential to fight blindness

Thu, 04/27/2017 - 23:07
Researchers have found a way to use artificial intelligence to fight a complication of diabetes that affects the eyes.

Can early experiences with computers, robots increase STEM interest among young girls?

Thu, 04/27/2017 - 17:07
Girls start believing they aren't good at math, science and even computers at a young age -- but providing fun STEM activities at school and home may spark interest and inspire confidence, suggests a new study.

A turbo engine for tracing neurons

Thu, 04/27/2017 - 16:09
Putting a turbo engine into an old car gives it an entirely new life -- suddenly it can go further, faster. That same idea is now being applied to neuroscience, with a software wrapper that can be used on existing neuron tracing algorithms to boost their ability to handle not just big, but enormous sets of data. The wrapper is called UltraTracer.

Light has new capacity for electronics

Thu, 04/27/2017 - 15:22
In 'Minority Report,' the protagonist uses gloves that give him the power of virtual manipulation. The light seems to allow him to control the screen as if it were a touchscreen, but he's touching nothing but air. That technology is still science fiction, but a new study may bring it closer to reality. Researchers report that they have discovered the photodielectric effect, which could lead to laser-controlled touch displays.

How state-of-the-art camera that behaves like the human eye could benefit robots and smart devices

Thu, 04/27/2017 - 15:09
Experts will explore how an artificial vision system inspired by the human eye could be used by robots of the future -- opening up new possibilities for securing footage from deep forests, war zones and even distant planets.

Looking for the quantum frontier

Thu, 04/27/2017 - 14:06
A new theoretical framework has been developed to identify computations that occupy the 'quantum frontier' - the boundary at which problems become impossible for today's computers and can only be solved by a quantum computer. The team demonstrates that these computations can be performed with near-term, intermediate, quantum computers.

Twitter could have predicted the outcome of the Brexit vote

Thu, 04/27/2017 - 14:06
Leave campaigners were not only victorious in the June 2016 Brexit vote but also in the battle of the Twittersphere, a new study reports.

Strong potential of E-health to increase vaccination coverage in Europe, study concludes

Thu, 04/27/2017 - 14:06
Twenty one EU/EEA countries have developed or are in the process of developing systems to digitally record information about vaccination, according to a new report. Fourteen of these countries already have a system in place, whereas innovative systems are being piloted in 7 countries.

Virtual humans help aspiring doctors learn empathy

Thu, 04/27/2017 - 13:17
Delivering bad news in a caring way -- and coping with a patient's reaction -- is a key skill for doctors. Intuitive technology is helping medical students learn the best approaches.

Using math to investigate possibility of time travel

Thu, 04/27/2017 - 13:17
After some serious number crunching, a researcher says that he has come up with a mathematical model for a viable time machine: a Traversable Acausal Retrograde Domain in Space-time (TARDIS). He describes it as a bubble of space-time geometry which carries its contents backward and forwards through space and time as it tours a large circular path. The bubble moves through space-time at speeds greater than the speed of light at times, allowing it to move backward in time.

System can 3-D print an entire building

Wed, 04/26/2017 - 22:30
Researchers have developed a system that can 3-D print the basic structure of an entire building.

Smartphone-controlled cells help keep diabetes in check

Wed, 04/26/2017 - 18:20
Cells engineered to produce insulin under the command of a smartphone helped keep blood sugar levels within normal limits in diabetic mice, a new study reports.

New theoretical approach to describing non-equilibrium phase transitions

Wed, 04/26/2017 - 18:17
Two physicists have offered a way to mathematically describe a particular physics phenomenon called a phase transition in a system out of equilibrium. Such phenomena are central in physics, and understanding how they occur has been a long-held and vexing goal; their behavior and related effects are key to unlocking possibilities for new electronics and other next-generation technologies.

2-D materials can conduct electricity at almost the speed of light

Wed, 04/26/2017 - 17:10
New two-dimensional quantum materials have been created with breakthrough electrical and magnetic attributes that could make them building blocks of future quantum computers and other advanced electronics. The researchers explored the physics behind the 2-D states of novel materials and determined they could push computers to new heights of speed and power.
