DNA computer brings 'intelligent drugs' a step closer

Fri, 02/17/2017 - 14:59
Researchers present a new method that should enable controlled drug delivery into the bloodstream using DNA computers. The team developed the first DNA computer capable of detecting several antibodies in the blood and performing subsequent calculations based on this input. This is an important step towards the development of smart, 'intelligent' drugs that may allow better control of medication with fewer side-effects and at lower cost.

Online-only pharmacies that don't require prescriptions could be helping to fuel antibiotic resistance, finds study

Fri, 02/17/2017 - 06:27
Antibiotics are illegally available without prescription on 45 per cent of online pharmacy websites surveyed, scientists have found.

Method to predict surface ozone pollution levels provides 48-hour heads-up

Thu, 02/16/2017 - 18:03
A novel air quality model will help air quality forecasters predict surface ozone levels up to 48-hours in advance and with fewer resources, according to a team of meteorologists.

Real-time MRI analysis powered by supercomputers

Thu, 02/16/2017 - 18:03
Researchers have developed a new, automated platform capable of returning in-depth analyses of MRI scans in a matter of minutes, rather than hours or days. The system has the potential to minimize patient callbacks, save millions annually, and advance precision medicine.

Social exclusion in virtual realities has a negative social and emotional impact in 'real' life

Thu, 02/16/2017 - 15:55
In this age of highly realistic computer games and increasingly popular social networks, social exclusion in virtual worlds is becoming more and more socially significant, as is demonstrated by the growing number of "cyber mobbing" cases. However, up until now, very little research has been carried out into the impact of social exclusion in the digital world upon real-life social behavior, and hardly any that addresses the latest developments such as Virtual Reality (VR) glasses. A study has now shown that exclusion from a virtual group has a significant negative impact upon willingness to help and social distance in the real world.

Breakthrough in 'wonder' materials paves way for flexible tech

Thu, 02/16/2017 - 15:38
Gadgets are set to become flexible, highly efficient and much smaller, following a breakthrough in measuring two-dimensional 'wonder' materials, report investigators.

Research opens door to smaller, cheaper, more agile communications tech

Thu, 02/16/2017 - 14:45
Research on the use of magnets to steer light has opened the door to new communications systems which could be smaller, cheaper and more agile than fiber optics.

Ultrafast camera for self-driving vehicles and drones invented

Thu, 02/16/2017 - 14:45
An ultrafast high-contrast camera has been developed that could help self-driving cars and drones see better in extreme road conditions and in bad weather. Unlike typical optical cameras, which can be blinded by bright light and unable to make out details in the dark, this new smart camera can record the slightest movements and objects in real time.

Sensors embedded in sports equipment could provide real-time analytics to your smartphone

Thu, 02/16/2017 - 14:45
In an effort to make big data analytics more accessible for the sports industry, researchers have utilized IoT devices -- low-cost sensors and radios -- that can be embedded into sports equipment (e.g., balls, rackets, and shoes), as well as in wearable devices.

A new spin on electronics

Wed, 02/15/2017 - 17:09
Modern computer technology is based on the transport of electric charge in semiconductors. But this technology's potential will be reaching its limits in the near future, since the components deployed cannot be miniaturized further. But, there is another option: using an electron's spin, instead of its charge, to transmit information. A team of scientists is now demonstrating how this works.

Is a stretchable smart tablet in our future?

Wed, 02/15/2017 - 15:14
Engineering researchers have developed the first stretchable integrated circuit that is made entirely using an inkjet printer, raising the possibility of inexpensive mass production of smart fabric.

Squishy supercapacitors bathed in green tea could power wearable electronics

Wed, 02/15/2017 - 15:14
Wearable electronics are here -- the most prominent versions are sold in the form of watches or sports bands. But soon, more comfortable products could become available in softer materials made in part with an unexpected ingredient: green tea. Researchers report a new flexible and compact rechargeable energy storage device for wearable electronics that is infused with green tea polyphenols.

How disturbances interact with a dynamic space-time fabric: 'Field patterns' as a new mathematical object

Wed, 02/15/2017 - 13:41
Mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory is called 'field patterns.'

Monitoring birds by drone

Wed, 02/15/2017 - 13:41
Forget delivering packages or taking aerial photographs -- drones can even count small birds. A new study tests this new approach to wildlife monitoring and concludes that despite some drawbacks, the method has the potential to become an important tool for ecologists and land managers.

Learning chemistry within Minecraft video game

Wed, 02/15/2017 - 13:41
Scientists are exploring whether teaching real-world science through a popular computer game may offer a more engaging and effective educational approach than traditional concepts of instruction. A group of 39 college students from diverse majors played an enhanced version of the popular video game "Minecraft" and learned chemistry in the process, despite being given no in-class science instruction.

GameSpace offers a playable visualization of 16,000 videogames

Wed, 02/15/2017 - 00:16
Finding information about videogames can now be a game in itself, thanks to researchers. They created GameSpace, a playable visualization of 16,000 videogames grouped according to common features and displayed in 3-dimensional space like a vast galaxy of games available for exploration.

Researchers develop 'living diode' using cardiac muscle cells

Tue, 02/14/2017 - 21:28
Research brings scientists one step closer to developing new forms of biorobotics and novel treatment approaches for several muscle-related health problems such as muscular degenerative disorders, arrhythmia and limb loss.

Astronomers propose a cell phone search for galactic fast radio bursts

Tue, 02/14/2017 - 21:28
Fast radio bursts seem to come from distant galaxies, but there is no obvious reason that, every once in a while, an FRB wouldn't occur in our own Milky Way galaxy too. If it did, astronomers suggest that it would be 'loud' enough that a global network of cell phones or small radio receivers could 'hear' it.

Optimizing data center placement, network design to strengthen cloud computing

Tue, 02/14/2017 - 18:05
Telecommunication experts estimate the amount of data stored 'in the cloud' or in remote data centers around the world, will quintuple in the next five years. Whether it's streaming video or business' database content drawn from distant servers, all of this data is -- and will continue in the foreseeable future to be -- accessed and transmitted by lasers sending pulses of light along long bundles of flexible optical fibers.

A theoretical physicist reassures the lovelorn
