In the US, someone suffers a heart attack every 34 seconds -- their heart is starved of oxygen and suffers irreparable damage. Engineering new heart tissue in the laboratory that could eventually be implanted into patients could help, and scientists are reporting a promising approach tested with rat cells. They published their results on growing cardiac muscle using a scaffold containing carbon nanofibers
As part of his PhD, postdoctoral research fellow Dr Daniel Tune has designed a computer modelling system that shows which combination of carbon nanotubes absorb the most sunlight, therefore providing the most energy.
Researchers have discovered a novel solid state reaction which lets kesterite grains grow within a few seconds and at relatively low temperatures. For this reaction they exploit a transition from a metastable wurtzite compound in the form of nanorods to the more stable kesterite compound.
The sixth annual BBVA Foundation Frontiers of Knowledge Award in the Basic Sciences category goes to German physicists Maximilian Haider , Harald Rose and Knut Urban for 'greatly enhancing the resolving power of electron microscopy by developing aberration-corrected electron optics, a breakthrough enabling subatomic precision'.
Some may think of turkeys as good for just lunch meat and holiday meals. But bioengineers at the University of California, Berkeley, saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable detectors of toxins or airborne pathogens.
