Read moreInsulating buildings with seaweed
Although this natural material is regarded as a waste product and generally ends up as landfill, this readily abundant and renewable material is in fact far too valuable to be thrown away. The seaweed displays a variety of characteristics that make it of interest to the building trade, such as virtual non-flammability and resistance to mould.

Read moreDoped carbon material produces low-cost energy and reduces CO2
Researchers from the University of Granada (UGR) have developed a new material using doped carbon that allows low-cost energy to be produced and also reduces the amount of CO2 released into the atmosphere. The recently-patented material is a gel that enables the CO2 to be turned back into hydrocarbons via electro-catalytic transformation, with great savings both in time and money.

Read moreStatistical physics offers a new way to look at climate
New research suggests that statistical simulations rooted in basic physics could make for new climate models that are more useful and require less brute-force computing power. A new paper shows how statistical simulations can be applied to fluid jets like the ones in Earth's atmosphere and oceans.
