Phys.org / Heat-induced nanoscale structures unlock electromechanical properties in ceramics
Scientists have developed a new way to make ceramic materials that can better withstand extreme heat and continue performing reliably in sensors and actuators. The approach creates tiny structures throughout the material ...
Phys.org / Florida Keys heat wave reveals nearly fourfold death risk for diseased coral
Disease and heat pose a deadly combination for coral reefs, according to a new University of Georgia study published in the journal Coral Reefs.
Phys.org / 'Flying rivers' above South America form drainage networks resembling those on land
Water does not flow only through rivers on the ground. Vast quantities of water also move through the atmosphere, carried by winds from oceans and land before eventually falling as precipitation hundreds or even thousands ...
Phys.org / Pollen study reveals the hidden history of grasses
Scientists used machine learning and super-resolution microscopy to overcome a challenge that has stymied research into the natural history of grasses for decades. Their method allowed them to detect subtle differences among ...
Phys.org / What a locust can teach us about how neuromodulators alter odor processing
When you walk into a bakery and smell fresh cookies, the enticing smell draws you in. After you eat a handful of cookies, though, the same smell likely doesn't send you back for more. Researchers in the McKelvey School of ...
Phys.org / Farmer-macaque conflict in Algeria poses a complicated conservation challenge
One of the hardest challenges in wildlife conservation arises when the habitat of a species in need of protection overlaps with land used by humans. Wolves and bears can kill livestock, elephants can damage homes and other ...
Phys.org / Sharks' inner ears reveal surprising diversity that may reflect evolution more than environment
A new study of shark anatomy suggests the shape of their inner ears is far more variable than expected, and this variation could have more to do with their evolutionary history than where they live or what they eat.
Phys.org / Dressed for danger: Venomous snakes are more likely to stand out
Researchers at the University of Galway in Ireland have found that venomous snakes are significantly more likely than nonvenomous species to have colors that stand out against their natural surroundings.
Phys.org / Precision IVF tracks how mouse embryos switch on their genome
A new study from EMBL Rome shows how embryos precisely coordinate gene activity during early development. The research is published in the journal Science Advances.
Dialog / Why Great Plains rivers depend on wetlands as well as climate
When a prairie river carries more water in one year than another, the obvious place to look for an explanation is the sky. A year with more snow and rain should have more water in rivers. That was also how I initially thought ...
Phys.org / Manganese-doped carbon nanodots could rival existing MRI contrast agents
Contrast agents are compounds routinely used in clinical analysis to enhance differentiation between tissues or to increase the visibility of structures or fluids within the body, thus facilitating medical diagnosis. A study ...
Phys.org / Decades of data reveal major ecological shift in northern Baltic Sea
For decades, scientists have regarded phosphorus as the main nutrient limiting biological production in the Gulf of Bothnia. Now, a new study led by researchers at Umeå University shows that a fundamental change is underway.
