Roboticists demonstrate that their flying microrobots, nicknamed the RoboBees, can now perch during flight to save energy - like bats, birds or butterflies.
If you're a rattlesnake, you want to bring the right weapon to a squirrel fight. And that venomous weapon varies from place to place, evolutionarily calibrated to overpower the local squirrels' defenses, according to new research.
Scientists have mapped changes in composition of plant cell walls over space and time, providing new insights into the development and growth of all plants. The cell wall is a defining feature of plant cells, providing essential functions like strength and mechanical support to plant tissues.
Posing a significant threat to the native biodiversity in Japan, specifically that of threatened aquatic insects, some alien fishes, such as the bluegill, have become the reason for strict prohibitions. However, recently, 10 years after the law against their release into the wild has been adopted, its first infringement is reported by Japanese researchers. Curiously, the case was initially exposed on Twitter by an undergraduate student.
European honeybees are being poisoned with up to 57 different pesticides, according to new research. A new method for detecting a whole range of pesticides in bees could help unravel the mystery behind the widespread decline of honeybees in recent years, and help develop an approach to saving them.
Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans, fueling further climate change, a study suggests. Scientists studied a 26,000-year-old sediment core to find out how the ocean's ability to take up atmospheric CO2 has changed over time, and found that when silicon was least abundant in ocean waters corresponded with relatively warm climates, low levels of atmospheric iron, and reduced CO2 uptake by the oceans' plankton.
For what may be the first time, NOAA and partner scientists eavesdropped on the deepest part of the world's ocean and instead of finding a sea of silence, discovered a cacophony of sounds both natural and caused by humans.
Scientists have discovered a novel way to make plastic from carbon dioxide and inedible plant material, such as agricultural waste and grasses. Researchers say the new technology could provide a low-carbon alternative to plastic bottles and other items currently made from petroleum.
A new report warns of the potential for major negative impacts on fish and fish habitat caused by large hydroelectric dams, like that currently under evaluation through the Next Generation Hydro initiative. The report, which focuses on north-western Canada, notes that substantial destruction of fish habitats caused by such a dam, along with additional threats and effects will be either very expensive or impossible to mitigate.
For the first time, researchers have attempted to measure all the material leaving and entering a mountain range over more than a million years, and discovered that erosion caused by glaciation during ice ages can, in the right circumstances, wear down mountains faster than plate tectonics can build them.
