Their cell generated a current stronger than any previously recorded from such a device, and worked as efficiently in dim light as in bright light.

This innovation could be a step toward wider adoption of solar power in places like British Columbia and parts of northern Europe where overcast skies are common. With further development, these solar cells—called “biogenic” because they are made of living organisms—could become as efficient as the synthetic cells used in conventional solar panels. — University of British Columbia

In the microbial metropolises that thrive in and on the human body, underground networks of viruses loom large. A closer look at human skin has found that it's teeming with viruses, most of which don't target us but infect the microbes that live there.

Almost 95 percent of those skin-dwelling virus communities are unclassified...Those unknown viruses may prune, manipulate, and hide out in the skin’s bacterial communities, which in turn can make the difference between human health and disease... — Ars Technica

Scientists in Korea have discovered that using antibacterial soap when hand-washing is no more effective than using plain soap, according to a paper published today in the Journal of Antimicrobial Chemotherapy... The study examined the effect of triclosan...on bacteria in two ways. The first was to examine the bactericidal effects of triclosan in soaps against all 20 strains, and the second compared the ability of antibacterial and non-antibacterial soap to remove bacteria from human hands... — Science Daily

Until present, we knew of similar patterns created from saline solutions and isolated proteins, but this is the first report that demonstrates how whole bacterial cells can manage the crystallisation of sodium chloride (NaCl) and generate self-organised biosaline structures of a fractal or dendritic appearance. — AlphaGalileo
