The northern and central Great Barrier Reef have recorded their highest amount of coral cover since the Australian Institute of Marine Science (AIMS) began monitoring 36 years ago. However, average coral cover in the southern region decreased due to ongoing crown-of-thorns starfish outbreaks. While the Reef experienced its fourth major bleaching event in the past seven years this year, it didn't reach the intensity of earlier events and was not expected to lead to mass coral mortality.

Using single calcite crystals with varying surface roughness allows engineers to simplify the complex physics that describes fault movement. Researchers now show how this simplification may lead to better earthquake prediction.

As warming ocean temperatures threaten the existence of coral reefs, scientists have successfully used an extremely high-resolution computer simulation of ocean circulation to identify possible 'thermal refugia' where these biodiverse ecosystems are more likely to survive.

A research team has created a computer modelling program to help scientists predict the effect of climate damage and eventual restoration plans on coral reefs around the globe. This is a critical objective because climate change is killing many coral species and can lead to the collapse of entire coral reef ecosystems, according to researchers.

A new study reveals that introduced donkeys and indigenous pumas are helping to resurrect extinct food webs in Death Valley.

Globally, dairy producers face increasing challenges regarding sustainability, including declining numbers of workers in the agricultural sector, while continuing to meet increasing demand for nutritious and affordable food. Dairy systems must now focus on more sustainable production that reflects economic, environmental, and social goals. A new report explores labor time-use on Irish pasture-based dairy farms in the busy spring and summer seasons.

A new lab study on garden eels shows how these shy creatures use their burrows, and change their movement and posture, when feeding in strong currents.

Rising annual temperatures and dwindling yearly precipitation across the mid-latitudes of Central Asia have extended its desert climate 60 miles northward since the 1980s, says a recent study.

Scientists investigating the growth of Arctic vegetation have found that seed dispersal and fire will slow its land expansion in the long term, despite more favorable conditions from a warming planet.

While many U.S. policy makers are calling for reshoring and nearshoring to combat trade disruptions caused by COVID-19, new research suggests retrenchment of global supply chains is unlikely to happen in the post-pandemic context.

A new study reveals that the phenomenon in deep reefs in which corals display glowing colors (fluorescence) is intended to serve as a mechanism for attracting prey. The study shows that the marine animals on which corals prey recognize the fluorescent colors and are attracted to them.

Researchers report direct observations of size-resolved ice nucleating particles in the central Arctic, spanning the entire sea ice growth and decline cycle. Their results show a strong seasonality of these particles, with lower concentrations in the winter and spring, and enhanced concentrations during summer melt from local biology.

A novel three-dimensional model of the fluid stored deep in Earth's crust along the Cascadia Subduction Zone provides new insight into how the accumulation and release of those fluids may influence seismic activity in the region.

Using data from the eruption of the underwater volcano near Tonga in 2022, researchers used disturbances in Earth's upper atmosphere to track the airwaves that cause tsunami. Their findings may lead to speedier predictions of these giant waves.

Using details from historical newspaper accounts and letters, seismologists have learned more about Haiti's 1860 Jour de Pâques (Easter Sunday) earthquake sequence, and how it might have impacted the country's most recent devastating earthquakes.

Researchers have established that the destruction of ozone over the Arctic in the spring causes abnormal weather throughout the northern hemisphere, with many places being warmer and drier than average -- or too wet.

New research found that nearly 300,000 birders traveled to the state and spent about $378 million in 2016. Birdwatching supported roughly 4,300 jobs in Alaska that year.

A new analysis of observed temperatures shows the Arctic is heating up more than four times faster than the rate of global warming. The trend has stepped upward steeply twice in the last 50 years, a finding missed by all but four of 39 climate models.

New research suggests the brain function of otherwise-healthy individuals exposed to event trauma has the ability to 'bounce back' over time once the threat resolves. Researchers conducted a follow-up study on a group of Cantabrians, who had been exposed to trauma during the region's earthquakes over a decade ago.
