Scientists 'must be allowed to cry' about destruction of nature

Scientists witnessing the destruction of the natural world must be supported and 'allowed to cry,' researchers say.

New tool visualizes nature's benefits worldwide

The researchers set out to understand where nature contributes the most to people and how many people may be affected by future changes. By 2050, up to 5 billion people could be at higher risk of water pollution, coastal storms and under-pollinated crops.

Key uncertainties identified for models of mosquito distribution in the US

A computational analysis has identified key regions in the United States where model-based predictions of mosquito species distribution could be improved.

Sharing data for improved forest protection and monitoring

Although the mapping of aboveground biomass is now possible with satellite remote sensing, these maps still have to be calibrated and validated using on-site data gathered by researchers across the world.

Scientists track wheat aphids and their natural enemies for better pest management in Pakistan

Scientists have studied the distribution and population dynamics of wheat aphids and their natural enemies in Pakistan through seasons and periods of time. This research could be useful to develop better pest management methods and safer, healthier crops in wheat production.

Placenta transit of an environmental estrogen

The human fetus is considered to be particularly sensitive to environmental contaminants. A team has now been able to demonstrate for the first time how the widespread food estrogen zearalenone behaves in the womb. Using a new analytical method, it was shown that the xenoestrogen migrates through the placenta and is partially converted to other harmful substances.

New study analyzes FEMA-funded home buyout program

An analysis of FEMA's 30-year-old property buyout program offers new insight into the growing debate on managed retreat -- moving people and assets out of flood-prone areas.

Solution to Ice Age ocean chemistry puzzle

New research into the chemistry of the oceans during ice ages is helping to solve a puzzle that has engaged scientists for more than two decades. At issue is how much of the CO2 that entered the ocean during ice ages can be attributed to the 'biological pump', where atmospheric carbon is absorbed by phytoplankton and sequestered to the seafloor as organisms die and sink.

Sunlight degrades polystyrene faster than expected

Researchers show that polystyrene, one of the world's most ubiquitous plastics, may degrade in decades or centuries when exposed to sunlight, rather than thousands of years as previously thought.

Removing invasive mice from the Farallon Islands would benefit threatened birds

New research shows the significant negative impact that invasive, non-native house mice on the Farallon Islands are having to the threatened ashy storm-petrel. Original modeling by ecologists shows the potential impacts to the petrel's population if mice are allowed to remain. The super-abundant mice encourage migrating burrowing owls to stay on the island, who later in the winter switch from eating mice to preying on the petrels.

Nanoparticles may have bigger impact on the environment than previously thought

In a first-of-its-kind study, researchers have shown that nanoparticles may have a bigger impact on the environment than previously thought.

Infectious disease in marine life linked to decades of ocean warming

New research shows that long-term changes in diseases in ocean species coincides with decades of widespread environmental change.

Warm ocean water attacking edges of Antarctica's ice shelves

Upside-down 'rivers' of warm ocean water are eroding the fractured edges of thick, floating Antarctic ice shelves from below, helping to create conditions that lead to ice-shelf breakup and sea-level rise, according to a new study. The findings describe a new process important to the future of Antarctica's ice and the continent's contribution to rising seas. Models and forecasts do not yet account for the newly understood and troubling scenario, which is already underway.

Meet Siamraptor suwati, a new species of giant predatory dinosaur from Thailand

Fossils discovered in Thailand represent a new genus and species of predatory dinosaur, according to a new study.

Reef fish caring for their young are taken advantage of by other fish

Among birds, the practice of laying eggs in other birds' nests is surprisingly common. This phenomenon, known as brood parasitism, was unknown in coral reef fish because most marine fish don't provide any parental care at all. Now, however, biologists studying an unusual kind of coral reef fish that does care for its young have found that, sure enough, other fish are taking advantage of this to get free parental care for their offspring.

Hush, little baby: Mother right whales 'whisper' to calves

A recent study explores whether right whale mother-calf pairs change their vocalizations to keep predators from detecting them.

Single-particle spectroscopy of CsPbBr3 perovskite reveals the origin low electrolumine

Researchers have used the method of single-particle spectroscopy to study electroluminescence in light-emitting devices. They discovered that efficient charge funneling between individual perovskite nanocrystals and the phenomenon of emission blinking are responsible for the low efficiencies of perovskite light-emitting devices.

Chemical evolution -- One-pot wonder

Before life, there was RNA: Scientists show how the four different letters of this genetic alphabet could be created from simple precursor molecules on early Earth -- under the same environmental conditions.
