It is usually believed that ferroelectricity can appear in insulating or semiconducting materials rather than in metals, because conducting electrons of metals always screen out the internal static electric field…

Scientists often refer to the neutrino as the “ghost particle.” Neutrinos were one of the most abundant particles at the origin of the universe and remain so today. Fusion reactions in…

In the coming years and decades, various nations want to explore the moon, and plan to send astronauts there again for this purpose. But on our inhospitable satellite, space radiation…

A molecule that can mimic the function of zaxinone, a natural growth-promoting plant metabolite, has been designed and fabricated by an international team led by KAUST and the University of…

For over 15 years, ETH Professor Andreas Hierlemann and his group have been developing microelectrode-array chips that can be used to precisely excite nerve cells in cell cultures and to…

Mitochondria are the powerhouses of our cells, generating energy that supports life. A giant molecular proton pump, called complex I, is crucial: It sets in motion a chain of reactions,…

This pest insect uses sugar from its food to prevent the activation of the mustard oil bomb in cruciferous plants. Worldwide dreaded crop pest of hundreds of plant species Whiteflies…

Current practices of the poultry industry have raised ethical and ecological concerns: ethical concerns include the culling of day-old male chicks of egg-laying breeds; ecological concerns include the import of…

UBC researchers say yes Breadfruit is sustainable, environmentally friendly and a high-production crop. A fruit used for centuries in countries around the world is getting the nutritional thumbs-up from a…

Orchids are quite decorative. However, many orchid species are also threatened by land conversion and illegal harvesting. But only a fraction of those species is included in the IUCN Red…

These systems could potentially overcome computational hurdles faced by current digital technologies. In the September issue of the journal Nature, scientists from Texas A&M University, Hewlett Packard Labs and Stanford…

3D nonlinear ferro-fluid-based hyperbolic metamaterials may contribute to ultra-fast all-optical hyper-computing. Metamaterials–nanoengineered structures designed for precise control and manipulation of electromagnetic waves–have enabled such innovations as invisibility cloaks and super-resolution…
