Air pollution found to affect marker of female fertility in real-life study

Ovarian reserve, a term widely adopted to reflect the number of resting follicles in the ovary and thus a marker of potential female fertility, has been found in a large-scale study to be adversely affected by high levels of air pollution.

National trash: Reducing waste produced in US national parks

When you think of national parks, you might picture the vast plateaus of the Grand Canyon, the intricate wetlands of the Everglades, or the inspiring viewscapes of the Grand Tetons. You probably don't envision 100 million pounds of mashed water bottles, barbecue-smudged paper plates, and crumpled coffee cups -- but that is the staggering quantity of garbage that is generated in our National Parks each year. And handling that amount of waste is becoming a huge problem.

Crop pests more widespread than previously known

Insects and diseases that damage crops are probably present in many places thought to be free of them, new research shows.

Ancient intervention could boost dwindling water reserves in coastal Peru

Methods used 1,400 years ago could boost water availability during Lima's dry season, according to new research.

Melting of Himalayan glaciers has doubled in recent years

A newly comprehensive study shows that melting of Himalayan glaciers caused by rising temperatures has accelerated dramatically since the start of the 21st century.

Plate tectonics may have driven 'Cambrian Explosion'

The quest to discover what drove one of the most important evolutionary events in the history of life on Earth has taken a new, fascinating twist.

Antarctic marine life recovery following the dinosaurs' extinction

A new study shows how marine life around Antarctica returned after the extinction event that wiped out the dinosaurs. A team studied just under 3000 marine fossils collected from Antarctica to understand how life on the sea floor recovered after the Cretaceous-Paleogene (K-Pg) mass extinction 66 million years ago. They reveal it took one million years for the marine ecosystem to return to pre-extinction levels.

Unexpected culprit: Wetlands as source of methane

Wetlands are an important part of the Earth's natural water management system. The complex system of plants, soil, and aquatic life serves as a reservoir that captures and cleans water. However, as cities have expanded, many wetlands were drained for construction. In addition, many areas of land in the Midwest were drained to increase uses for agriculture to feed a growing world.

Global commodities trade and consumption place the world's primates at risk of extinction

A recent study highlights the fact that the economic benefits of commodity export for primate habitat countries has been limited relative to the extreme environmental costs of pollution, habitat degradation, loss of biodiversity, continued food insecurity and the threat of emerging diseases.

Carbon-neutral fuel made from sunlight and air

Researchers have developed a novel technology that produces liquid hydrocarbon fuels exclusively from sunlight and air. For the first time worldwide they demonstrate the entire thermochemical process chain under real field conditions.

Warming waters in western tropical Pacific may affect West Antarctic Ice Sheet

Warming waters in the western tropical Pacific Ocean have significantly increased thunderstorms and rainfall, which may affect the stability of the West Antarctic Ice Sheet and global sea-level rise, according to a new tudy.

Large summer 'dead zone' forecast for Chesapeake Bay after wet winter and spring

Ecologists are forecasting a large Chesapeake Bay 'dead zone' in 2019 due to well-above-average river flows associated with increased rainfall in the watershed since last fall.

Old ice and snow yields tracer of preindustrial ozone

Using rare oxygen molecules trapped in old ice and snow, US and French scientists have answered a long-standing question: How much have 'bad' ozone levels increased since the start of the Industrial Revolution?

Electric vehicles would be a breath of fresh air for Houston

Researchers are expressing hope for the future of Houston's breathable air, despite the city's poor rankings in the American Lung Association's 2019 'State of the Air' report. The report, released in April, ranked Houston ninth nationally for worst ozone pollution and 17th for particle pollution. Researchers say replacing at least 35 percent of Houston's gasoline cars and diesel trucks with electric vehicles by 2040 will reduce pollution and improve air quality by 50 percent.

Consequences of Deepwater Horizon oil spill

Marine snow is the phenomena of flakes of falling organic material and biological debris cascading down a water column like snowflakes. But an oil spill like Deepwater Horizon will add oil and dispersants to the mix, making marine oil snow that is can be toxic to organisms in deep-sea ecosystems.
