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.

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.
In many regions of the world, populations of large mammalian herbivores have been displaced by cattle breeding—for example, in Kenya, hippos by large herds of cattle. This can change aquatic ecosystems due to significant differences in the amount and type of dung input. Researchers from the University of Eldoret in Kenya, the University of Innsbruck and the Leibniz-Institute of Freshwater...
Planting woody plant species alongside crops could double the number of insect pollinators helping farmers produce food, new research has demonstrated for the first time.

For 30 years, MBARI ecologist Ken Smith and his colleagues have studied deep-sea communities at a research site called Station M, located 4,000 meters (2.5 miles) below the ocean's surface and 290 kilometers (180 miles) off the coast of Central California. A recent special issue of the journal Deep-Sea Research features 16 new papers about research at Station M by scientists from around the world....

Increased tree canopy or green space could decrease morbidity and mortality for urban populations - particularly in areas with lower socioeconomic status where existing tree canopies tend to be the lowest.
A team of researchers 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.
Researchers have discovered an important gene in plants that could help agricultural crops collaborate better with underground fungi -- providing them with wider root networks and helping them to absorb phosphorus. The discovery has the potential to increase agricultural efficiency and benefit the environment.
By discovering a trick the hepatitis C virus uses to evade the immune system, scientists have identified a new antiviral defence system that could be used to treat many virus infections, according to new research.
A research team has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor is that it moves exactly at the boundary between classical motion and quantum tunneling -- and has revealed puzzling phenomena to researchers in the quantum realm.
A study has examined fossil reefs near to the now-submerged Red Sea shorelines that marked prehistoric migratory routes from Africa to Arabia. The findings suggest this coast offered the resources necessary to act as a gateway out of Africa during periods of little rainfall when other food sources were scarce.
Behavioral biologists have now been able to demonstrate for the first time that male guinea pigs are still able to adapt their hormone systems to changes in their social environment in adulthood.
A regional coalition-guided multifaceted approach engaged health systems, long-term care facilities, state and local governments, and organizations to rapidly respond to the outbreak.
New data from TERAVOLT, a global consortium that tracks outcomes of people with thoracic cancers affected by COVID-19, offers clues as to why they experienced a high death rate of 33 percent when the coronavirus swept across Europe.
Although most broken bones can be mended with a firm cast and a generous measure of tender loving care, more complicated fractures require treatments like bone grafting. Researchers have now created superior bone grafts using primitive stem cells. They found that these cells help create very fertile scaffolds needed for bone to regenerate at the site of repair.
A new study shows how vastly complex communication networks can efficiently convey large amounts of information to the human brain. Researcher found that works of literature, musical pieces, and social networks have a similar underlying structure that allows them to share information rapidly and effectively.
In many regions of the world, populations of large mammalian herbivores have been displaced by cattle breeding, for example in Kenya the hippos by large herds of cattle. This can change aquatic ecosystems due to significant differences in the amount and type of dung input. Researchers have therefore taken a closer look at the dung of hippopotamus and cattle.
Researchers model the role of relaxation time as T cells bind to invaders or imposters, and how their ability to differentiate between the two triggers the body's immune system.
Researcher uncovers why most of the records left by ancient rivers preserve commonplace processes.
Researchers have developed motion capture technology that enables you to digitize your dog without a motion capture suit and using only one camera.
Researchers evaluated several human antibodies to determine the most potent combination to be mixed in a cocktail and used as a promising anti-viral therapy against the virus that causes COVID-19.
A first-in-class clinical trial suggests a novel treatment measurably slowed progression of non-alcoholic fatty liver disease to its more progressive and deadly form.
