The flavor and aroma of a fine chocolate emerge from its ecology, in addition to its processing. But can you be certain that the bar you bought is really from the exotic locale stated on the wrapper? Now, researchers are presenting a method for determining where a particular chocolate was produced by looking at its…

An innovator developed a new approach to creating popular thin films for devices across a broad range of fields, including optics, acoustics and electronics. Epitaxial lithium niobate (LNO) thin films are an attractive material for electronics and other devices. These films offer flexibility and other properties that are important to manufacturers. Epitaxial lithium niobate (LNO)…

The future of Samoa’s electricity system could go green, a new study has shown. Pacific Island nations are particularly susceptible to climate change and face high costs and energy security issues from imported fossil fuels. For these reasons many Pacific Island nations have developed ambitious 100 per cent renewable energy targets. However, they have not…

Many semiconducting materials are possible candidates for solar cells. In recent years, perovskite semiconductors in particular have attracted attention, as they are both inexpensive and easy to process and enable high efficiencies. Now a new study shows how terahertz (TRTS) and microwave spectroscopy (TRMC) can be used to reliably determine the mobility and lifetime of…

Global warming is likely to increase the number of people requiring hospitalization due to critically low sodium levels in the blood, a condition known as hyponatremia. A new study projects that a temperature rise of 2 degrees Celsius would increase the burden on hospitals from hyponatremia by almost 14 percent. «Our study is the first…

Scientists studied a method for recycling unused concrete with wood fibers. They found the conditions that produce new building materials with bending strength even greater than the original concrete. This work may help reduce the CO2 emissions associated with manufacturing new concrete. Concrete has long been the material of choice for construction our modern world,…

Researchers have new evidence that could help rapidly boost efforts to scale-up the adoption of clean cooking with liquefied petroleum gas (LPG) in sub-Saharan Africa. The new study suggests that supply-side interventions such as shortening the distance to LPG retail points and improving access to multi-burner LPG stoves could help increase the consumption of the…

Researchers have used an unmanned aerial system (or drone) to gather data on schooling juvenile Atlantic bluefin tuna in the Gulf of Maine. This pilot study tested whether a drone could keep up with the tuna while also taking photographs that captured physical details of this fast-moving fish. This pilot study tested whether a drone…

Fetching drinking water in low and middle income countries can cause serious injury, particularly for women. A new study reveals dangers including falls, traffic accidents, animal attacks, and fights, which can result in broken bones, spinal injuries, lacerations, and other physical injuries. The work draws on a survey of 6,291 randomly selected households across 24…

Microbes living within the slimy biofilms of some coral species may help protect the coral against excess nitrogen levels, according to new research. Now, researchers at MIT and the Woods Hole Oceanographic Institution (WHOI), in collaboration with oceanographers and marine biologists in Cuba, have identified microbes living within the slimy biofilms of some coral species…
