US west-coast earthquake faults might be linked
Two of North America’s most fearsome earthquake zones could be linked. Controversial analysis of sea-floor cores suggests that quakes on the Cascadia fault off California can trigger tremors on the San Andreas. Layers of churned-up, sandy sediment usually caused by earthquakes seem to have formed near the Cascadia fault just before similar ones near the San Andreas.
Brazilian researchers post paper anonymously
Brazilian researchers investigating the cause and extent of wildfires in the Amazon are so afraid that their findings might jeopardize their jobs that some have remained anonymous on a paper just published in a leading climate-change journal. The paper conflict with the Brazilian government’s official narrative, which suggests the fires are not that unusual, says one of the named authors, Erika Berenguer, who is based in the United Kingdom. “People are definitely afraid. They are concerned about their future and if they could suffer some sort of governmental retaliation,” she says.
Sounds of life revitalize reefs
The crackling, buzzing and whooping sounds of a healthy reef tempt young fish to re-colonize degraded areas. Researchers used loudspeakers to broadcast healthy soundscapes over piles of coral simulating patches of dead reef. After 40 days, there were twice as many damselfish — abundant, easy-to-observe reef dwellers — on the acoustically enriched patches than on areas without a soundtrack.

How to build a better malaria vaccine
The first vaccine against malaria, RTS,S, offers protection that was once thought by some to be impossible. But the vaccine offers only a partial shield against the shape-shifting parasitic disease: over the four years of the vaccine’s phase III trial, it prevented around 30% of serious cases. Scientists are working on a wide variety of alternatives that they hope will save even more lives.

Dive inside a singularity
The question of what really happens in the unexplorable centre of a black hold is much more complex than just a mathematical breaking point. Physicists exploring theoretical black holes that better mimic the real world have come closer than ever to describing what lies at the bottom of the Universe’s deepest well.

Podcast: Huge genetic survey of Asia
Researchers have released the first data from an ambitious project to sequence the genomes of 100,000 people from populations across Asia. The pilot phase is: a whole-genome reference data set from 1,739 individuals across 219 population groups and 64 countries.

Where I work

“I define myself as a ‘grounded mystic’,” says astrobiologist Nathalie Cabrol of her time exploring the barren high deserts of South America for clues to extreme microbial life. “I’m trying to understand the Universe we are living in and how to search for life in it. That’s the ‘grounded’ aspect. The ‘mystic’ part is that I’m not afraid of letting my mind wander in those spaces.”
