Mammalian cells may consume bacteria-killing viruses to promote cellular health      (via sciencedaily.com)     Original source 

Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell. A study suggests that mammalian cells internalize phages as a resource to promote cellular growth and survival.

Conduction electrons drive giant, nonlinear elastic response in Sr2RuO4      (via sciencedaily.com)     Original source 

The hardness of a material normally is set by the strength of chemical bonds between electrons of neighboring atoms, not by freely flowing conduction electrons. Now a team of scientists has shown that current-carrying electrons can make the lattice much softer than usual in the material Sr2RuO4.

Discovery of three novel minorisa species, the smallest predatory marine picoplankton      (via sciencedaily.com)     Original source 

Researchers have made a significant discovery by identifying and characterizing three novel species within the Minorisa genus of marine picoplankton. Before this study, only one species of Minorisa was recognized. This finding reveals previously unseen diversity of Minorisa, thereby enhancing species identification and our understanding of its ecological functions in marine ecosystems.

Membrane transporter ensures mobility of sperm cells      (via sciencedaily.com)     Original source 

Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such a transporter and its mechanism. These findings will enable a better understanding of the molecular foundations of reproductive capacity and could, in the long term, contribute to developing new approaches to treating fertility disorders and new methods of specific contraception.

A potentially cheaper and 'cooler' way for hydrogen transport      (via sciencedaily.com)     Original source 

Researchers have developed a new hydrogen energy carrier material capable storing hydrogen energy efficiently and potentially more cheaply. Each molecule can store one electron from hydrogen at room temperature, store it for up the three months, and can be its own catalyst to extract said electron. Moreover, as the compound is made primarily of nickel, its cost is relatively low.

Dispersions of polymer particles in a liquid phase (latexes) have many important applications in coatings technology, medical imaging, and cell biology. A team of researchers has now developed a method to produce stable polystyrene dispersions with unprecedentedly large, and uniform, particle sizes. Narrow size distributions are essential in many advanced technologies, but were previously difficult to produce photochemically.

Diapers can be recycled 200 times faster with light      (via sciencedaily.com)     Original source 

More than 100,000 tons of diapers are disposed of annually in Germany. Vast amounts of valuable resources, such as diaper liners, end up in the trash. The liners consist of special polymers, so-called superabsorbers. Researchers have now succeeded in considerably improving their complex recycling process. They use UV radiation to degrade the chemical chains that keep the polymers together. No chemicals are needed. Recycling at room temperature is 200 times faster than conventional recycling. The recycled polymers can then be processed to new adhesives and dyes.

Sunflower extract fights fungi to keep blueberries fresh      (via sciencedaily.com)     Original source 

Opening a clamshell of berries and seeing them coated in fuzzy mold is a downer. And it's no small problem. Gray mold and other fungi, which cause fruit to rot, lead to significant economic losses and food waste. Now, researchers report that compounds from sunflower crop waste prevented rotting in blueberries. They suggest the food industry could use these natural compounds to protect against post-harvest diseases.
