Light-emitting electrochemical cells, LEC, is a newly invented lighting technology.

In his thesis, physicist Amir Asadpoordarvish, Umeå University in Sweden, shows how a LEC can be produced through spraying three layers of ink on a substrate and emit light by the current from an ordinary battery.

LEC components can be sprayed onto complicated surfaces, for example to make a light-emitting fork.

Unlike standard cigarettes, the components of electronic cigarettes are not regulated and standardized, thus they vary widely between products. The characteristics of these e-cigarette elements, including their delivery systems, combustion apparatuses, and the composition of the nicotine solutions they contain may affect the levels of potentially hazardous substances in the vapor they produce, according to a new study presented at the 2015 American Thoracic Society International Conference.

People with ulcerative colitis may benefit from taking the live, multi-strain probiotic drink to reduce intestinal inflammation, according to the results of a new study presented at Digestive Disease Week 2015.(1)

The American Cancer Society estimated that 220,800 new cases of prostate cancer will be diagnosed in the United States in 2015. Approximately 27,540 men will die of the disease, accounting for 5 percent of all cancer deaths.

XML markup of taxonomic research and specimen data is a valuable tool for structuring the incessantly accumulating biodiversity knowledge. It allows for the opportunity to collectively use the currently fragmented information for more detailed analysis.

30 of physical activity, irrespective of its intensity, 6 days a week is linked to a 40% lower risk of death from any cause among elderly men, finds research published online in the British Journal of Sports Medicine. Boosting physical activity levels in this age group seems to be as good for health as giving up smoking, the findings suggest.

The researchers base their findings on people taking part in the Oslo Study, which invited almost 26,000 men born between 1923 and 1932 for a health check in 1972-3 (Oslo I).

A new discovery by Monash University researchers could save thousands of lupus sufferers each year from serious illness or death caused by secondary infections.

The use of glycated hemoglobin (sugar-bound hemoglobin, or HbA1c) is now in almost universal use to assist doctors in the diagnosis of type 2 diabetes. However new research published in Diabetologia (the journal of the European Association for the Study of Diabetes) highlights how anemia--a common condition in the general population, especially in women--can lead to a false diagnosis of diabetes based on HbA1c, when a person's blood sugar control is actually normal. The research is by Dr Emma English, University of Nottingham, UK, and colleagues.

A part of the performance degradation mechanism of the advanced, electrodeless, helicon plasma thruster with a magnetic nozzle, has been revealed by the research group of Dr. Kazunori Takahashi and Prof. Akira Ando at Tohoku University's Department of Electrical Engineering.

Digital signatures are mechanisms for authenticating the validity or authorship of a certain digital message and they aim to be digital counterparts to real (or analog) signatures. The concept was introduced by Diffie and Hellman in 1976. Notice that, when certified, digital signatures have the same legal power as traditional signatures.

Researchers have demonstrated a new metal matrix composite that is so light that it can float on water. A boat made of such lightweight composites will not sink despite damage to its structure. The new material also promises to improve automotive fuel economy because it combines light weight with heat resistance.

Although syntactic foams have been around for many years, this is the first development of a lightweight metal matrix syntactic foam. It is the work of a team of researchers from Deep Springs Technology (DST) and the New York University Polytechnic School of Engineering.

Many of us are familiar with electrolytic splitting of water from their school days: if you hold two electrodes into an aqueous electrolyte and apply a sufficient voltage, gas bubbles of hydrogen and oxygen are formed. If this voltage is generated by sunlight in a solar cell, then you could store solar energy by generating hydrogen gas.This is because hydrogen is a versatile medium of storing and using "chemical energy".

Scientists have discovered a way to regrow bone tissue using the protein signals produced by stem cells. This technology could help treat victims who have experienced major trauma to a limb, like soldiers wounded in combat or casualties of a natural disaster. The new method improves on older therapies by providing a sustainable source for fresh tissue and reducing the risk of tumor formation that can arise with stem cell transplants.

The new 9-valent human papillomavirus vaccine, can potentially prevent 80 percent of cervical cancers in the United States, if given to all 11- or 12-year-old children before they are exposed to the virus.

University of Melbourne animal welfare researcher Dr Jean-Loup Rault says the prospect of robopets and virtual pets is not as far-fetched as we may think.

His paper in the latest edition of Frontiers in Veterinary Science argues pets will soon become a luxury in an overpopulated world and the future may lie in chips and circuits that mimic the real thing.

"It might sound surreal for us to have robotic or virtual pets, but it could be totally normal for the next generation," Dr Rault said.
