Researchers show how how the bombardier beetle concocts its deadly explosives and in the process, learn how evolution gave rise to the beetle's remarkable firepower.
A new study has found that rehabilitated Kemp's ridley and loggerhead sea turtles experience a substantial stress response when transported to release locations in the southern United States but that the turtles remained physically stable and ready for release.
Lawns that are only cut once a month can give low-growing plants a chance to flower, letting insects thriveLawn mowers are back in action now that June is wet and the grass is growing again after the spring drought, but it’s worth mowing less often to let wildflowers and their insect pollinators thrive.A survey by volunteers for the charity Plantlife found that 80% of lawns supported the...
Since the 1980s, researchers have been running experiments in search of particles that make up dark matter, an invisible substance that permeates our galaxy and universe. Coined dark matter because it gives off no light, this substance, which constitutes more than 80 percent of matter in our universe, has been shown repeatedly to influence ordinary matter through its gravity. Scientists know it is...
The Torridon sandstone in northwestern Scotland preserves six kilometers of river sediment from Precambrian times. But what sort of geological events were able to leave their mark for researchers to find 1 billion years later?
If you want to see one of the wonders of the natural world, just startle a bombardier beetle. But be careful: when the beetles are scared, they flood an internal chamber with a complex cocktail of aromatic chemicals, triggering a cascade of chemical reaction that detonates the fluid and sends it shooting out of the insect's spray nozzle in a machine-gun-like pulse of toxic, scalding-hot vapor. The...
The lives of honeybees are shortened -- with evidence of physiological stress -- when they are exposed to the suggested application rates of two commercially available and widely used pesticides.
Magnetic ''quasiparticles'' called magnons may help scientists detect dark matter.
An insect fossil found near Kamloops, B.C., has researchers questioning the global movement of animals and evolutionary changes based on...
Like finding that needle in the haystack every time, your T cells manage what seems like an improbable task: Quickly finding a few invaders among the many imposters in your body to trigger its immune response.
No satellite stays the same once launched into space. How much it changes can go unnoticed—until something bad happens.

The lives of honeybees are shortened—with evidence of physiological stress—when they are exposed to the suggested application rates of two commercially available and widely used pesticides, according to new Oregon State University research.
Equity (or, its counterpart, inequity) plays a fundamental role in the evaluation of the different dimensions of social welfare. But how can we consider and compare its different dimensions? These issues are in fact traditionally considered and compared across individuals—be it within national boundaries or across countries, but also over time, when we consider the distribution of resources over...
A team of researchers led by Arizona State University (ASU) School of Earth and Space Exploration professor Lindy Elkins-Tanton has provided the first ever direct evidence that extensive coal burning in Siberia is a cause of the Permo-Triassic Extinction, the Earth's most severe extinction event. The results of their study have been recently published in the journal Geology.
