Dog-friendly dining isn't just a trend, it's good for business, new research shows‎

Restaurants that go beyond simply allowing dogs on patios by offering dedicated menu items for them can significantly boost customer traffic, spending and word-of-mouth, according to new research from Toronto Metropolitan University.

Fast fashion's carbon footprint can be reduced across its life cycle, new study suggests‎

Fast fashion is built on cheap, short-lived garments, especially cotton and polyester T-shirts. To sustain its profits, the industry relies on high production frequency, short product lifespan and a globalized supply chain. All these elements contribute to making the industry a major source of global pollution.

Scientists capture first molecular-level images of water reorganization during a reaction crucial for life‎

Some of nature's most important chemical reactions rely on the coupled movement of negatively and positively charged particles. These processes play central roles in photosynthesis, catalysis and biological energy conversion yet remain difficult to observe.

Does the Nepal glacier collapse signal a new climate risk?‎

Does the devastating flooding unleashed by the collapse of a section of a glacier in the Nepali Himalayas signal a new kind of risk in a world warmed by climate change? Here's what scientists told AFP.

Breathable smart sensor developed for real-time hazardous gas detection on masks‎

A research team led by Sungwon Lee, a professor in the Department of Physics and Chemistry at DGIST, developed a hierarchical nano-on-nano structure by directly growing graphene nanowalls (GNWs) on polymer nanofibers and successfully used the structure to enhance the sensing performance of wearable gas sensors. The technology is expected to be applied to next-generation wearable sensors for real-time monitoring of individuals' breathing environments or hazardous gases in industrial settings.

Honey bees can serve as sentinels for environmental health‎

Honey bees (Apis mellifera) are widely known as essential pollinators, but researchers using a "One Health" approach have also identified them as biological sentinels of environmental health. Honey bees continuously interact with their surrounding environment through the collection of nectar, pollen and water and can therefore be exposed to contaminants present in agricultural and natural ecosystems. Their health may consequently provide valuable information about environmental pressures affecting biodiversity and ecosystem functioning.

Motorboat noise stunts growth and impairs predator escape in reef fish, study shows‎

Coral reef fish that are exposed to motorboat noise grow up smaller and less able to dodge predators, new research shows. Scientists played either boat noise or natural reef sounds to a species from the Great Barrier Reef called the spiny chromis, both as embryos and soon after hatching.

Why some earthquakes caused by fracking come with warning signs‎

Fracking, the injection of high-pressure fluid to fracture rock and release oil or gas, can trigger earthquakes. While some sites generate small tremors beforehand that may provide an early warning, others produce few or none.

Joro spiders eat wider range of insects than Georgia's native orb weavers‎

When Joro spiders first arrived stateside more than a decade ago, scientists worried the massive black-and-yellow spiders would gorge themselves on the same bugs as native spiders (or even the native spiders themselves). If the invasive arachnids did make massive meals of Georgia's insects, the local orb weaver population—already facing dangers from insecticide and pesticide use—could suffer.
