Pacific cities much older than previously thought      (via sciencedaily.com)     Original source 

New evidence of one of the first cities in the Pacific shows they were established much earlier than previously thought, according to new research. The study used aerial laser scanning to map archaeological sites on the island of Tongatapu in Tonga, showing Earth structures were being constructed in Tongatapu around AD 300.

Deforestation harms biodiversity of the Amazon's perfume-loving orchid bees      (via sciencedaily.com)     Original source 

A survey of orchid bees in the Brazilian Amazon, carried out in the 1990s, is shedding new light the impact of deforestation on the scent-collecting pollinators, which some view as bellwethers of biodiversity in the neotropics.

New approach needed to save Australia's non-perennial rivers      (via sciencedaily.com)     Original source 

An extensive review of current research incorporating geomorphology, hydrology, biogeochemistry, ecology and Indigenous knowledges identifies prevailing factors that shape water and energy flows in Australia's non-perennial rivers -- but the review also points to research deficiencies that must be addressed if these river systems are to be preserved and protected.

Impact of climate change on marine life much bigger than previously known      (via sciencedaily.com)     Original source 

Fish and invertebrate animals are far more affected by warmer and more acidic seawater than was previously known. The big gain of the new method is that more details become known about effects of climate change on species.

Humans converted at least 250,000 acres of estuaries to cities, farms in last 35 years      (via sciencedaily.com)     Original source 

Worldwide over the past 35 years, dams and land reclamation activities converted 250,000 acres of estuary -- an area roughly 17 times the size of Manhattan -- to urban land or agricultural fields, with most land conversion and estuary loss in rapidly developing countries, a new study finds. The findings could help developing countries avoid problems faced by countries that have already lost or degraded their estuaries.

Atmospheric and economic drivers of global air pollution      (via sciencedaily.com)     Original source 

Carbon monoxide emissions from industrial production have serious consequences for human health and are a strong indicator of overall air pollution levels. Many countries aim to reduce their emissions, but they cannot control air flows originating in other regions. A new study looks at global flows of air pollution and how they relate to economic activity in the global supply chain.

Deep parts of Great Barrier Reef 'insulated' from global warming -- for now      (via sciencedaily.com)     Original source 

Some deeper areas of the Great Barrier Reef are insulated from harmful heatwaves -- but that protection will be lost if global warming continues, according to new research.

Boreal forest and tundra regions worst hit over next 500 years of climate change, study shows      (via sciencedaily.com)     Original source 

Modelling climate change over a 500 year period shows that much of the boreal forest, the Earth's northernmost forests and most significant provider of carbon storage and clean water, could be seriously impacted, along with tundra regions, treeless shrublands north of the boreal forest that play a significant role in regulating the Earth's climate.

Climate change threatens Antarctic meteorites      (via sciencedaily.com)     Original source 

Antarctica harbors a large concentration of meteorites imbuing the icy continent with an unparalleled wealth of information on our solar system. However, these precious meteorites are rapidly disappearing from the ice sheet surface due to global warming, according to a new study.

Adult fish struggle to bounce back in marine protected areas      (via sciencedaily.com)     Original source 

Many marine protected areas are falling short of their most basic purpose: to rebuild struggling fish populations. In a new study, scientists looked at the age breakdown of reef fish in marine protected areas for the first time. They discovered in almost all of them, adult fish populations -- vital to spawning the next generation -- have either flatlined or declined.

NASA's Webb probes an extreme starburst galaxy      (via sciencedaily.com)     Original source 

A team of astronomers has used NASA's James Webb Space Telescope to survey the starburst galaxy Messier 82 (M82). Located 12 million light-years away in the constellation Ursa Major, this galaxy is relatively compact in size but hosts a frenzy of star formation activity. For comparison, M82 is sprouting new stars 10 times faster than the Milky Way galaxy.
