Scientists create most powerful micro-scale bio-solar cell yet
Researchers have created a micro-scale biological solar cell that generates a higher power density for longer than any existing cell of its kind.

Need for speed makes genome editing efficient, if not better
Researchers have developed a computational model to quantify the mechanism by which CRISPR-Cas9 proteins find their genome-editing targets.

'Hiding in plain sight:' Discovery raises questions over scale of overlooked biodiversity
Scientists have used cutting edge DNA technology to demonstrate that one of Europe's top freshwater predators is actually two species rather than one.

Keratin, proteins from 54-million-year-old sea turtle show survival trait evolution
Researchers have retrieved original pigment, beta-keratin and muscle proteins from a 54-million-year-old sea turtle hatchling. The work adds to the growing body of evidence supporting persistence of original molecules over millions of years and also provides direct evidence that a pigment-based survival trait common to modern sea turtles evolved at least 54 million years ago.

Oysters offer hot spot for reducing nutrient pollution
Marine scientists have quantified potentially denitrifying bacteria in the oyster gut and shell, with important implications for efforts to reduce nutrient levels in coastal waters through oyster restoration.

A new target for marijuana
Cellular-level changes to a part of the brain's reward system induced by chronic exposure to the psychoactive component of marijuana may contribute to the drug's pleasurable and potentially addictive qualities, suggests a study in young mice.

How cells induce inflammation upon detection of cytoplasmic DNA
A research team has elucidated the mechanism by which human cells induce inflammation upon detection of cytoplasmic DNA. Notably, the signal network involved differs from that used in the same context in mice.

New antibiotic resistance genes found
Researchers have found several previously unknown genes that make bacteria resistant to last-resort antibiotics. The genes were found by searching large volumes of bacterial DNA.

Gutters teem with inconspicuous life
Scientists have shown that Parisian street gutters are oases of microscopic life, home to microalgae, fungi, sponges, and mollusks. Grouped into communities, these microorganisms may help clean rainwater and urban waste by decomposing solid debris and pollutants. A deeper understanding of the role and composition of these communities could help elucidate the services rendered by gutter ecosystems. The researchers' findings are the first to reveal the unsuspected biodiversity of microscopic life in Paris city streets.

Worms reveal secrets of aging
Investigators have identified a new molecular pathway that controls lifespan and healthspan in worms and mammals. Researchers have shown that worms with excess levels of certain proteins lived longer and healthier than normal worms. In addition, mice with excess levels of these proteins demonstrated a delay in blood vessel dysfunction associated with aging. The study has major implications for our understanding of aging and age-associated disorders.
