Frogs in hot water: Habitat shrinking for Gondwana rainforest mountain frogs
Mechanism of metal-to-insulator transition in ruthenium phosphide suggests a new way of looking at solids
Urban myth has it that a frog placed in cold water that's brought to the boil will not react, dying a horrible death. Clearly this is a fallacy, yet climate change is forcing a similar predicament for mountain frog species stranded on "islands in the sky," according to a new Southern Cross University study.
A genetic circuit guides microorganisms to stop fighting and work together in a cell factory
A group from Nagoya University in Japan has discovered a never-before-seen form of ruthenium phosphide with an unusual configuration of atoms and electrons in its cooled state. This may resolve the puzzle of how a metal can be a conductor at high temperatures, but an insulator at lower temperatures.

Most Asian countries are far behind biodiversity targets for protected areas, finds study of 40 countries
In our daily lives, we rely on weather forecasts to know whether it will rain tomorrow. The monitoring and prediction of space weather such as geomagnetic storms and substorms are also vital for the operation safety of satellites outside the atmosphere and the living conditions of astronauts in space. However, space weather is far more unpredictable than the weather on Earth, which depends on...
Climate change will cause Pacific's low-oxygen zone to expand even more by 2100, study finds
Protected areas are one of the most effective tools for safeguarding biodiversity, but new research published today has found that most Asian countries failed to achieve a global minimum target of protecting at least 17% of land by 2020. Under current trends, the outlook for achieving the Global Biodiversity Framework's 2030 target to protect at least 30% of land is bleak, with Asia set to miss...
To track disease-carrying mosquitoes, researchers tag them with DNA barcodes
For thousands of kilometers along the western coasts of the Americas, low-oxygen waters known as oxygen minimum zones stretch out into the Pacific Ocean. In part due to climate change, this oxygen-starved region is likely to get wider and deeper, expanding by millions of cubic kilometers by the end of the century, models in a new study predict. Larger oxygen minimum zones threaten marine...
Sex roles in the animal kingdom driven by the ratio of females to males
West Nile, Zika, dengue and malaria are all diseases spread by bites from infected mosquitoes. To track the threat of such diseases over large populations, scientists need to know where the mosquitoes are, where they've been, and where they might go.
Nations must embrace change in order to tackle biodiversity crisis, researchers say
How picky should females and males be when they choose a mate? How fiercely should they compete for mates? And how much should they engage in raising their offspring? The answers to these questions largely depend on the ratio of adult females to males in the social group, population or species.
Hawaii volcano shoots lava fountains 200 feet high: USGS
Governments should embrace the realities of shifting biodiversity rather than "investing in futile efforts to return the natural world to its historic state," a new study argues.
Fountains of lava up to 200 feet (60 meters) high have been fired into the air from Hawaii's Mauna Loa, geologists say, generating rivers of molten rock from the world's largest active volcano.
