Blood vessels made from fibroblasts and fibrin grew in sync with the three lambs into which the vessels were transplanted, replacing part of the lambs' pulmonary arteries, scientists reported in Nature Communications. If bioengineered arteries can be made from human cells and behave similarly, children with congenital heart defects might be able to forgo multiple open-heart surgeries, study coauthor Robert Tranquillo said.

The methods applied to building tall suspension bridges may soon be used for wind turbines, allowing their towers to exceed the current height limit of 262 feet. The Hexcrete system that researchers are working on at Iowa State University would open the way for turbine towers to access the richer energy sources of stronger, steadier winds above 330 feet.

A team of researchers from the Technion-Israel Institute of Technology successfully tested a simulated pipeline to replace sea water in the Dead Sea. The sea is losing water because much of the Jordan River is diverted for farming, and the sea water loss is the suspected cause of sinkholes in the region.

Electrically powered aircraft are making some advances but are held back by battery weight, a problem Luke Workman believes he can solve with a new design that could power even supersonic airliners. The solution comes in the form of a lightweight battery with a vast surface area -- as big as the wings of a supersonic plane, for instance -- used as an electrode plate.
