Study finds climate-driven greening is reshaping East Asia's air pollution‎

The effects of climate change extend far beyond rising temperatures. As forests and other vegetation respond to a warming world, they also change the amount of biogenic emissions released into the atmosphere, influencing the formation of ozone (O3) and fine particulate pollution. Yet many atmospheric chemistry models still estimate these emissions using vegetation data from 2003, despite major ecological changes across East Asia over the past two decades.

Study suggests natural sounds help us feel more attached to specific places‎

A new study suggests the sounds around us have a significant impact on how we feel about physical spaces, with natural sounds—such as birdsong—associated with a greater sense of attachment to a given place. The study draws on data from a large-scale participatory science project involving more than 1,000 citizen scientists.

Ways to help protect Australia's birds and mammals from bird flu‎

The deadly H5N1 strain of bird flu has now spread from migratory birds to infect resident Australian birds. Clusters of dead birds have been found in several locations. The virus will inevitably infect other wildlife, most notably mammals.

Venus's polygonal plains could point to a watery past‎

Venus may be overwhelmingly inhospitable today, but many planetary scientists believe that it wasn't always this way. Billions of years ago, some observational evidence suggested that our planetary neighbor may have looked far more like Earth, complete with oceans potentially capable of harboring life.

Butterflies are on the move as the planet warms: New research‎

Imagine spotting a butterfly species in your garden that you have never seen before. You might take a photo and upload it to a citizen science app or tell a local nature group about your new encounter. It feels like a small moment of joy.

Drought-hardy ryegrass raises new weed management challenge‎

A study by La Trobe University researchers has found annual ryegrass, the most damaging weed in Australian grain systems, can adjust its growth and reproduction to survive under drought stress, making it potentially harder to manage as climate conditions become more variable.

Study probes Malaysia's corporate bond strategy: Offering Islamic bonds expanded corporate financing access‎

In the late 1990s, Malaysia created a new way for corporations to raise money by issuing bonds that comply with Islamic law, which prohibits the payment or collection of interest.

Melting sea ice combines with Arctic sea to make clouds‎

Scientists have uncovered a previously unknown natural process that dramatically increases the number of cloud-forming particles in the Arctic atmosphere—potentially altering cloud cover, sunlight reflection and future climate change.
