Employing a library of more than 1,000 chemicals, scientists investigated how agrochemicals affect insect populations. The scientists found that exposure to non-fatal amounts of 57 percent of the chemicals altered behavior in fruit fly larvae, while higher levels compromised long-term survival after acute exposure. These observations were worsened when the...

New research has revealed Marri trees are critical to the survival of more than 80 species of native bee in Western Australia's South West region, which is one of the world's most biologically rich but threatened biodiversity hotspots.

Maternal antibodies passed across the placenta can interfere with the response to the malaria vaccine, which would explain its lower efficacy in infants under five months of age, according to new research. The findings suggest that children younger than currently recommended by the WHO may benefit from the RTS,S and...

Scientists have directly measured the behavioral responses of some of the most common marine mammals to military sonar. And the finding that surprised them most was that these animals were sensitive to the sounds at much lower levels than previously predicted.

Scientists characterize novel enzymes from deep-sea microbes with a key function in the ethane degradation process, revealing surprises in the metabolism of these organisms.

The transition from water to land is one of the most significant events in the history of life on Earth. Now, a team of roboticists, palaeontologists and biologists is using robots to study how the ancestors of modern land animals transitioned from swimming to walking, about 390 million years ago.

The new mammal lived in Colorado 70 to 75 million years ago -- a time when a vast inland sea covered large portions of the state, and animals like sharks, turtles and giant crocodiles abounded.
