Troublesome green algae serve as nanocoating substrate in record-setting battery
Unwanted blooms of Cladophora algae throughout the Baltic and in other parts of the world are not entirely without a positive side. A group of researchers at the Angstrom Laboratory at Uppsala University have discovered that the distinctive cellulose nanostructure of these algae can serve as an effective coating substrate for use in environmentally friendly batteries.

Read moreRNAs taking center stage
RNAs, serving as a mere intermediary between DNA and proteins, were long regarded as a poor relation by researchers, attracting little interest. However, following the discovery of small RNAs known as microRNAs, they have increasingly been moving into the limelight.

Read moreFast transistors for a digital world
Our society is insatiable as far as the transfer of data is concerned. Consequently, increasingly faster and cheaper transistors are being developed. In row in recent months, researchers from ETH Zurich have now broken the world record for the switching speed of nitride-based transistors that use silicon as a substrate several times.

Read moreCalculations may improve temperature measures for microfluidics
If you wanted to know if your child had a fever or be certain that the roast in the oven was thoroughly cooked, you would, of course, use a thermometer that you trusted to give accurate readings at any temperature within its range. However, it isn't that simple for researchers who need to measure temperatures in microfluidic systems?tiny, channel-lined devices used in medical diagnostics, DNA forensics and lab-on-a-chip chemical analyzers?as their current 'thermometer' can only be precisely calibrated for one reference temperature.

Virtual characters, or avatars, will be part of a new learning tool designed to attract and retain young European science students. An EU-funded project is developing a programme that emphasises teaching scientific concepts in an interactive environment. The main purpose of the three-year project is to get students more involved in the learning process and to capture their interest in science.
