In world first, researchers convert sunlight to electricity with over 40 percent efficiency Posted: 07 Dec 2014 06:16 AM PST Australia's solar researchers have converted over 40 percent of the sunlight hitting a solar system into electricity, the highest efficiency ever reported. A key part of the prototype's design is the use of a custom optical bandpass filter to capture sunlight that is normally wasted by commercial solar cells on towers and convert it to electricity at a higher efficiency than the solar cells themselves ever could.

Nanoparticle cluster manufacturing technique using DNA binding protein developed Posted: 05 Dec 2014 02:51 PM PST Scientists have used the zinc finger protein to develop a new manufacturing technique for size-controllable magnetic nanoparticle clusters.

Complementary light switchable proteins and superresolution reveal moving protein complexes in live cells at single molecule level Posted: 05 Dec 2014 08:35 AM PST A new method uses photoactivatable complementary fluorescent proteins (PACF) to observe and quantify protein-protein interactions in live cells at the single molecule level.

Gravity: It’s the law even for cells Posted: 05 Dec 2014 08:35 AM PST The average animal cell is 10 microns across but why? Bioengineers take their story of gravity in cells one step further, describing how cells manage to support thousands of membrane-less compartments inside the nucleus.

Rescuing the golgi puts brakes on Alzheimer’s progress Posted: 05 Dec 2014 08:35 AM PST Alzheimer's disease (AD) progresses inside the brain in a rising storm of cellular chaos as deposits of the toxic protein, amyloid-beta (Aβ), overwhelm neurons. An apparent side effect of accumulating Aβ in neurons is the fragmentation of the Golgi apparatus, the part of the cell involved in packaging and sorting protein cargo including the precursor of Aβ. But is the destruction the Golgi a kind of collateral damage from the Aβ storm or is the loss of Golgi function itself part of the driving force behind Alzheimer's?

An unholy alliance: Colon cancer cells in situ co-opt fibroblasts in surrounding tissue to break out Posted: 05 Dec 2014 08:35 AM PST Researchers report that they have evidence of a coordinated attack on the basement membrane of human colon cells by cancer cells in situ and CAF cells in the extracellular matrix that begins long before the actual translocation of cancer cells.
