Tree-ring, ice core and volcano experts teamed up to identify one of the most climatically impactful volcanic eruptions in 4,000 years -- Aniakchak II. In the process, they narrowed down potential dates for the Thera volcano eruption.

For the last decade, biologists have documented a worrying decline in insect abundance, which some fear may prelude an arthropod apocalypse. These studies, however, are primarily carried out in temperature regions while the tropics, which harbor the vast majority of insect species, largely remains a black box. In a new...

Geophysicists have developed a method that allows them to investigate the composition of the Earth with better results.

Two-pore ion channels are present in many eukaryotes -- both animals and plants. While the possible involvement of these channels in environmental stress responses have been discussed in higher plants, their localizations and functional significance remain largely unknown. Now, researchers have found the missing pieces of evolutionary history of two-pore...

A study of nearly 9,000 children found those who eat a vegetarian diet had similar measures of growth and nutrition compared to children who eat meat. The study also found that children with a vegetarian diet had higher odds of underweight weight status, emphasizing the need for special care when...

A recent study provides insights for developing climate-smart conservation strategies by looking at the global network of protected areas, evaluating potential for shifts in where plants and animals occur due to climate change. Findings point to the need for strategic conservation plans that transcend international borders to protect at-risk species.

When it comes to fixing carbon, plants have nothing on soil bacteria that can do it 20 times faster. The secret is an enzyme that 'juggles' reaction ingredients. Scientists hope to optimize this process for producing fuels, antibiotics and other products from CO2.

Biologists have discovered an aberrant protein that's deadly to bacteria. This erroneously built protein mimics the action of aminoglycosides, a class of antibiotics. The newly discovered protein could serve as a model to help scientists unravel details of those drugs' lethal effects on bacteria -- and potentially point the way...

A study indicates that antibiotics, which kill bacteria, boost the abundance of gut fungal microbiota. The phenomenon can be a contributing factor in the long-term adverse effects of antibiotics, such as inflammatory bowel diseases.

Four thousand years before Stonehenge was constructed, land within the World Heritage Site was covered by open woodland, with meadow-like clearings, inhabited by grazing animals and hunter-gatherers, according to new research.
