The arts, cultural and creative sectors can act as powerful catalysts for climate action, changing how people understand, engage with and act on climate change, new research from University College Cork (UCC) has found.
Q&A: Dynamic side of language development in toddlers
Overhearable speech (speech that may occur when caregivers are talking to each other in a child's presence) constitutes more than half of children's language exposure, but its role in language development remains underexplored. Researchers from the University of Chicago, The
Currents in an Arctic sea accelerate the sinking of carbon-carrying phytoplankton
Tiny plantlike organisms called phytoplankton that form the base of marine food webs topped by orcas, whales and sharks usually get eaten or slowly sink to the seafloor, carrying carbon as they go. Across most of the ocean, the descent from sunlit surface layers takes weeks.

Researchers find convenience, drinking water access and advertising drive global bottled water consumption
Over 1 million plastic water bottles are bought globally every minute. That translates into more than 1.3 billion every day and more than 500 billion every year. That's a lot of plastic, and much of it winds up in human bodies and landfills. The long-term health implications
Zika virus assembles without protein segment long deemed essential
For years, scientists were certain that two factors were involved in the assembly of active, highly infectious Zika viruses in human cells: a specific viral protein in its entirety and a turncoat human enzyme that assured viral maturity. New research suggests that Zika virus
Pigeons' proposed inner-ear compass runs into a noise problem
A pigeon turning its head might seem an unlikely electricity generator. Yet one proposed explanation for the bird's magnetic sense depends on exactly that: Turning through Earth's magnetic field would produce tiny electrical signals inside its ears. However, a theoretical study

A display of flowers has bloomed across Chile's Atacama Desert, one of the driest places on Earth, after the El Niño climate phenomenon brought heavy rain to the region.
Agency says sea turtle eggs laid on California beaches are a first for the US West Coast
A reptile believed to be struggling in sand at a Southern California beach was simply making history: a sea turtle laying eggs on the U.S. West Coast.
Livestock grazing may boost soil carbon storage in Iceland's subarctic grasslands
Grassland plants transfer large amounts of carbon to soil through their roots, and most of that carbon is stored underground. Therefore, promoting soil carbon storage can help combat climate change. Grazers feed on grassland plants, and conventional wisdom often assumes that

A study in Contemporary Economic Policy examined whether racial and ethnic differences in U.S. disability insurance approval rates reflect disparities in the determination process or broader differences in applicants' circumstances.
Research project identifies pathways to climate-resilient water and soil management
How can regions better adapt their water and soil resources to the impacts of climate change? After four years of research, the European collaborative project Blue Transition, led by the LIAG Institute for Applied Geophysics in Hanover, takes stock. The final report brings
The LHC just ruled out another hiding place for quantum black holes
Physicists searching through Large Hadron Collider data found no evidence that the machine has been producing microscopic quantum black holes, but the result sharply narrows where such exotic physics could still be hiding. These hypothetical black holes could form if extra
The Solar System chose fire over ice from the very beginning
Ancient iron meteorites reveal that some of the Solar System’s first solid bodies were built mostly from tiny heat-forged rock beads called chondrules, while water-rich dust was largely excluded. The finding pushes this selective planet-building process back to within the Solar
