Mysterious radio burst coming from deep space
Jun 17, 2020 13:17For the second time ever, astronomers have found a fast radio burst (FRB) that repeats on a regular, predictable cycle. This could mean that - at least in some cases - the wild unpredictability of mysterious deep-space FRBs could actually be a problem with our detection capabilities.

Climate worst-case scenarios may not go far enough, cloud data shows
Jun 17, 2020 13:04Worst-case global heating scenarios may need to be revised upwards in light of a better understanding of the role of clouds according to scientists. Recent modelling data suggests the climate is considerably more sensitive to carbon emissions than previously believed, and experts said the projections had the potential to be incredibly alarming, though they stressed further research would be needed to validate the new numbers.

Ancient Australian rocks suggest earth's continents were shifting earlier than thought
May 27, 2020 11:05Earth's continents are constantly on the move, it's a key feature of our planet, but that wasn't always the case. While some scientists think Earth's tectonic plates began pushing and pulling only a billion years ago, others think the whole process started nearly four billion years ago, when our planet was but an infant.

Microplastic pollution in oceans vastly underestimated, according to new study
May 25, 2020 12:50The abundance of microplastic pollution in the oceans is likely to have been vastly underestimated, according to research that suggests there are at least double the number of particles as previously thought. Scientists trawled waters off the coasts of the UK and US and found many more particles using nets with a fine mesh size than when using coarser ones usually used to filter microplastics.

Wildfires can reduce biodiversity: Can biodiversity be used to reduce wildfires?
Apr 30, 2020 14:03According to a new analysis of 57 peer-reviewed studies looking at the link between climate change and wildfire risk, the weather conditions that led to the Australian wildfires are set to become more common. The unanimous conclusion was that “climate change increases the frequency or severity of fire-favorable weather conditions.”

Disbelief in big cities as air pollution falls
Apr 12, 2020 19:20A nationwide lockdown imposed across India almost two weeks ago to stop the spread of the coronavirus — the largest lockdown of its kind attempted anywhere — has led to widespread chaos and suffering, especially among the country’s 300 million poor. Yet in Delhi, the world’s most polluted city, it has also resulted in some of the freshest air the capital has seen in decades.
