Polymeric fluids behavior revealed at the microscopic scale

Mon, 04/24/2017 - 13:39
An important concept in future healthcare is the development of devices called "lab on a chip". These "chips" are injected to fill specifically designed microscopic channels. These channels contain biosensors which detect, for example, specific markers for diseases within the fluid and provide a quick diagnosis. However, an arising issue is the size of the fluid sample injected inside the chip, with tiny volumes down to a billionth of a liter. Due to lack of available technologies, researchers do not yet fully understand how fluids -- particularly complex ones of biological origins -- behave at such small scales.

Space technologies improve surgeries back on earth

Sat, 04/22/2017 - 14:20
A novel surgical robotic system has been developed that provides tactile feedback and is capable of single-incision and natural orifice (incision-free) robotic surgery. The system minimizes surgical trauma and is safer than currently available robotic systems.

Facebook plays vital role in reducing government corruption, researchers find

Sat, 04/22/2017 - 14:17
An economics researcher says the popular social media website – and its open sharing of information – is a vital and often a significant tool against government corruption in countries where press freedom is curbed or banned.

New digital map shows changing racial diversity of America

Fri, 04/21/2017 - 16:33
A geography professor built the most detailed map of racial diversity yet to study the way America's neighborhoods are changing.

New survey: Snapchat and Instagram are most popular social media platforms among American teens

Fri, 04/21/2017 - 15:33
A new nationally representative survey of American teenagers age 13-17 finds that teens have shifted their favored social media platforms and are now most likely to use Instagram and Snapchat. The study also found that while almost all teens -- 91 percent -- use the regular text messaging tool on their mobile phones, 40 percent of teens also use messaging applications like Kik, WhatsApp, or Line on a smartphone.

Quantum mechanics is complex enough, for now...

Fri, 04/21/2017 - 14:37
Physicists have searched for deviations from standard quantum mechanics, testing whether quantum mechanics requires a more complex set of mathematical rules. To do so a research team designed a new photonic experiment using exotic metamaterials. Their experiment supports standard quantum mechanics and allows the scientists to place bounds on alternative quantum theories. The results could help to guide theoretical work in a search for a more general version of quantum mechanics.

Molecular libraries for organic light-emitting diodes

Fri, 04/21/2017 - 14:37
Organic light-emitting diodes (OLEDs) are promising candidates for flexible flat displays. By means of a screening process, it is now possible to identify more quickly lead structures with superior luminescence and charge-transport properties.

Application of statistical method shows promise mitigating climate change effects on pine

Thu, 04/20/2017 - 20:21
Confronting evidence that the global climate is changing rapidly relative to historical trends, researchers have developed a new statistical model that, when applied to the loblolly pine tree populations in the southeastern United States, will benefit forest landowners and the forest industry in future decades.

New quantum liquid crystals may play role in future of computers

Thu, 04/20/2017 - 18:18
The first 3-D quantum liquid crystals may have applications in quantum computing, report scientists. Liquid crystals fall somewhere in between a liquid and a solid: they are made up of molecules that flow around freely as if they were a liquid but are all oriented in the same direction, as in a solid. Liquid crystals can be found in nature, such as in biological cell membranes. Alternatively, they can be made artificially -- such as those found in the liquid crystal displays commonly used in watches, smartphones, televisions, and other items that have display screens.

Researchers unlock hardware's hidden talent for rendering 3-D graphics for science -- and video games

In the first known study of older adults learning computer programming, a cognitive scientist advocates coding skills for all ages.

Periodic model predicts spread of Lyme disease

Thu, 04/20/2017 - 13:02
Lyme disease is among the most common vector-borne illnesses in North America, Europe, and some parts of Asia. A spirochete bacterium called Borrelia burgdorferi causes the disease, and blacklegged ticks are responsible for the majority of North American transmissions. In a new paper, researchers present a mathematical model of Lyme disease that incorporates seasonality and climate factors.

Making batteries from waste glass bottles

Wed, 04/19/2017 - 15:24
Researchers have used waste glass bottles and a low-cost chemical process to create nanosilicon anodes for high-performance lithium-ion batteries. The batteries will extend the range of electric vehicles and plug-in hybrid electric vehicles, and provide more power with fewer charges to personal electronics like cell phones and laptops.

Online preconception health education tool positively impacts patient care

Wed, 04/19/2017 - 14:08
A research team has evaluated MyFamilyPlan and found that it enabled a significant increase in the proportion of women who reported discussing their reproductive health with their doctors.

Nanoparticles remain unpredictable

Wed, 04/19/2017 - 14:08
The way that nanoparticles behave in the environment is extremely complex. There is currently a lack of systematic experimental data to help understand them comprehensively, as environmental scientists have shown in a large overview study. A more standardized approach would help to advance the research field.

Degradable electronic components created from corn starch

Wed, 04/19/2017 - 14:08
As consumers upgrade their gadgets at an increasing pace, the amount of electronic waste we generate continues to mount. To help combat this environmental problem, researchers have modified a degradable bioplastic derived from corn starch or other natural sources for use in more eco-friendly electronic components.
