Removal of excess nitrogen is a critical step in the ecological restoration of eutrophic lakes. Microbially mediated dissimilatory nitrate reduction processes in lakes represent an important mechanism for nitrogen removal. However, lake ecosystems are fac

After surveying food market retailers in three New York City Chinatown districts, Cornell researchers have found genetic evidence that some endangered species of sea cucumbers—considered a pricey but nutritious dried delicacy—are being sold to consumers.

Antibiotics in the uppermost water surface, known as the sea surface microlayer, can significantly affect the number of bacteria present and contribute to the adaptation of marine bacteria against widely used antibiotics. In new research presented at ASM

Sepsis is a life-threatening infection complication and accounts for 1.7 million hospitalizations and 350,000 deaths annually in the U.S. Fast and accurate diagnosis is critical, as mortality risk increases up to 8% every hour without effective treatment.

The French Polynesian island Moorea is the most beautiful isle in the world, some say. Its lagoons are surrounded by reefs dominated by Porites corals.

Magnesium compounds are a common ingredient of many remedies designed to help people wind down and escape the stresses of modern life. However, a new study has shown it is not only humans that are using forms of the chemical as a way to help them survive

A novel study published in Nature Communications found that agroecosystems in Central Germany, specifically grasslands and croplands, may have an enhanced capacity to provide multiple goods and services simultaneously when land management reduces the use

Psychologists Benjamin Jones and Josep Call at the University of St Andrews, in the U.K., have found via behavioral experiments that chimpanzees know that they rely on luck when making guesses about certain things. Their paper is published in the journal

Parrots, songbirds, and hummingbirds can learn to make new sounds. No-one knew, but New Zealand's smallest bird, the rifleman or titipounamu, may have a rudimentary version of the same talent.

Paleontologists from the Institut Català de Paleontologia Miquel Crusafont (ICP), the University of Edinburgh (UK), the Universidade Federal de Santa Maria (Brazil), and the University of Toronto in (Canada) have shown that the early South American rodent

Scientists at St. Jude Children's Research Hospital have reported a way to improve molecular scale distance measurements using single-molecule fluorescence resonance energy transfer (smFRET). smFRET quantifies the excitation and emission properties of ch

New research by Swansea University and the University of Zurich has found that sharks retained high levels of functional diversity for most of the last 66 million years, before steadily declining over the last 10 million years to its lowest value in the p
