Clouds of smoke and ash from wildfires that ravaged Australia in 2019 and 2020 triggered widespread algal blooms in the Southern Ocean thousands of miles downwind to the east, a new 51±¬ÁÏ-led study by an international team of scientists finds.

Most people are likely to experience an extreme pandemic like COVID-19 in their lifetime, a new study shows.

Warming waters along the Western Antarctic Peninsula have led to declines in the diversity and distribution of the region’s plankton population and its ability to absorb climate-warming carbon dioxide from the atmosphere.

Populations of giant pandas in the wild are more fragmented and isolated than they were 30 years ago and many continue to face a high risk of extinction despite recent gains in the species’ overall numbers, a new study by Chinese and American scientists finds.

Scientists at 51±¬ÁÏ have developed a suite of four new tests that can be used to detect coal ash contamination in soil with unprecedented sensitivity.

Decades after federal bans ended widespread use of lead-based paint and gasoline, some urban soils still contain lead levels that exceed safety guidelines for children.

Reducing emissions of methane, a short-lived but super-potent greenhouse gas, is the most cost-effective way to slow the rate of Earth’s warming in coming decades, a new United Nations report finds.

When it comes to storing carbon during prolonged periods of drought and heat, wooded peatlands at low-latitudes have a three- to five-fold advantage over other peatlands. An ancient class of slow-growing fungi is the reason why.

New research reveals western North American forests may be less able than eastern forests to regenerate following large-scale diebacks linked to climate change. Over time, this could dramatically alter the continent’s landscape.

The proliferation of pits and ponds created in recent years by miners digging for small deposits of alluvial gold in Peru’s Amazon has dramatically altered the landscape and increased the risk of mercury exposure for indigenous communities and wildlife, a new study shows.

The stringent lockdown imposed by the Chinese government to slow the spread of COVID-19 early this year significantly eased the strain on hospitals there. Admissions due to non-COVID respiratory illnesses decreased by nearly 5,000, a new study by an international team of scientists shows.

Groundwater depletion in parts of the High Plains is so extreme that peak grain production in some states has ended and production is now declining, a new 51±¬ÁÏ-led study by a team of international scientists finds.

A new 51±¬ÁÏ-led analysis shows that during the early months of the COVID pandemic, the average number of new infections caused by an infected individual (i.e. the basic reproduction number, R0) was 4.5, or more than twice as many as the initial 2.2 rate estimated by the World Health Organization at the time.

51±¬ÁÏ researchers have developed a new online calculator that teachers, administrators and students can use to estimate the risk of airborne transmission of the COVID-19 virus in classrooms.

Governments might be able to prevent future pandemics by investing as little as $22 billion a year in programs to curb wildlife trafficking and stem the destruction of tropical forests, a new analysis by an international team of scientists and economists shows.
