Innovative anti-biofouling technologies can make shipping more eco-friendly

Organisms that stick to the lower structures of ships increase fuel consumption and costs of maintenance substantially. Currently, the organisms are killed with toxic biocides, but these chemicals need to be removed to protect our environment. Researchers are trying to develop environmentally friendly anti-biofouling technologies, such as nano-structured surfaces that make organisms fall off when the ships move.

Gold nanoparticles help earlier diagnosis of liver cancer

A research team led by Brown University reports some promising results for earlier diagnosis of hepatocellular carcinoma, the most common cancer to strike the liver. More than 500,000 people worldwide, concentrated in sub-Saharan Africa and Southeast Asia, are diagnosed with it yearly. Most of those afflicted die within six months.

Engineering researchers discover new source for generating 'green' electricity

University of Minnesota engineering researchers in the College of Science and Engineering have recently discovered a new alloy material that converts heat directly into electricity. This revolutionary energy conversion method is in the early stages of development, but it could have wide-sweeping impact on creating environmentally friendly electricity from waste heat sources.

Nanopores follow nature's design in tracking proteins

Dutch and Swiss researchers have developed a biomimetic nanopore that offers a sophisticated test and measurement platform for the way proteins enter the nucleus of a cell. This study provides evidence of how a biomimetic nuclear pore can be created to monitor how single proteins move across the pore.

Versatile membrane makes large-scale energy-efficient separation possible

Hessel Castricum from the University of Amsterdam has developed a versatile membrane that is capable of separating gas and liquid mixtures in an energy-efficient manner. The new membrane can probably be employed under industrial conditions on a large scale in the future. This has not been possible until now, because virtually all membranes developed so far are insufficiently stable.

Molecular robot can be programmed to follow instructions

Scientists have developed a programmable sub-microscopic molecular machine made of synthetic DNA that moves between track locations separated by 6nm. The robot, a short strand of DNA, follows instructions programmed into a set of fuel molecules determining its destination.
