(Phys.org)—As lithium resources continue to decline worldwide, the next generation of portable electronics will most likely be powered by something other than Li-ion batteries. One potential candidate is the sodium-ion (Na-ion) battery, which stands out because sodium is cheaper, non-toxic, and more abundant than lithium.
Organic light emitting diodes (OLEDs), which are made from carbon-containing materials, have the potential to revolutionize future display technologies, making low-power displays so thin they'll wrap or fold around other structures, for instance.
Cardiovascular risks of severe pediatric obesity, assessed among a recent study, have been recently published. The authors found that severely obese adolescents carry not only excess weight, but also have much higher risk for CVD than previously realized. Show More Summary
A team of astronomers, led by Darach Watson, from the University of Copenhagen used the Very Large Telescope's X-shooter instrument along with the Atacama Large Millimeter/submillimeter Array to observe one of the youngest and most remote galaxies ever found. They...
New research shows that seven compounds of the countless found in spider venom block a key step in the body's ability to pass pain signals to the brain. The hunt for a medicine based on just one of these compounds, which would open up a new class of potent painkillers, is now a step closer according to new research published in the British Journal of Pharmacology. read more
The new zinc-polyiodide redox flow battery uses an electrolyte that has more than two times the energy density of the next-best flow battery used to store renewable energy and support the power grid. It's high energy density, and resulting lower cost, make it ideal for large cities where space is at a premium.
“Where regions become warmer or wetter this may allow for increased agricultural output – while others may be harmful,” Eric Worrall reports: A new government report is creating shock in the Australian climate fraternity, with its almost blasphemous suggestion, that in some respects, the current global temperature might not be the ultimate climatic optimum we…
A low-cost antiseptic used to cleanse the cord after birth could help reduce infant death rates in developing countries by 12%, a systematic review published in The Cochrane Library suggests. Authors of the review found that when chlorhexidine was used on babies born outside of a hospital, it reduces the number of newborn babies who died or suffer from infections. read more
A new sequencing technique may provide a clearer picture of how genes in mitochondria, the "powerhouses" that turn sugar into energy in human cells, shape each person's inherited risk for diabetes, heart disease and cancer, according to a study. read more

Leaders of many of Australia’s top scientific research organisations have today called on the federal government to release A$150 million in vital science infrastructure funding, which is currently being withheld due to wrangling over the government’s proposed higher education reforms. read more
Scientists have observed an increase in carbon dioxide's greenhouse effect at Earth's surface for the first time. They measured atmospheric carbon dioxide's increasing capacity to absorb thermal radiation emitted from Earth's surface over an 11-year period at two locations in North America. Show More Summary
Adults who closely followed the Mediterranean diet were 47 percent less likely to develop heart disease over a 10-year period compared to similar adults who did not closely follow the diet, according to a new study.
A new study published today in the journal Laterality, has found that people are quicker to categorise a face as being male when it is shown to the left side of the brain. read more
Natural gas powered solid oxide fuel cells, located at the point of use to produce electricity for facilities the size of big box stores, could provide economic and environmental benefits, with additional research, according to new study.
Many birds spend only a few months of the year in their breeding range before leaving to spend the winter in another region or even on another continent, and models that only make use of data from one season may not paint a complete picture. Show More Summary
Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome, new research shows.
Gout appears to have a protective effect for the brain, possibly thanks to uric acid, the chemical in a person's blood that can crystallize, leading to gout, said a team of researchers from north America. Gout, the most common inflammatory...Show More Summary
