Despite significant advances in wireless technology, the manufacturing industry continues to turn to wired forms of communication such as Ethernet or fibre optics for its most critical tasks. A new study by Cristina Cano and the full professor Xavier Vilajosana, researchers from the Wireless Networks (WiNe) group at the Internet Interdisciplinary Institute (IN3), opens the door to the use of wireless technologies with power and reliability that are comparable to fibre optics and that could replace cabled connections.

A team of scientists from Siberian Federal University together with their colleagues from Novosibirsk studied the effect of nanoparticles on oil production efficiency. When added to the water that displaces oil from a reservoir, nanoparticles improve the separation of oil drops from mine rock and their washing to the surface. The work received a grant from the Russian Science Foundation, and an article about it was published in the Journal of Molecular Liquids.

To reach the Mariana Islands in the Western Pacific, humans crossed more than 2,000 kilometres of open ocean, and around 2,000 years earlier than any other sea travel over an equally long distance. They settled in the Marianas around 3,500 years ago, slightly earlier than the initial settlement of Polynesia.

Earth's forests are indispensable for both humans and wildlife: they absorb CO2, provide food for large parts of the world's population and are home to all sorts of animals.

However, forest conservation measures are lagging in many countries, says Laura Vang Rasmussen, an assistant professor at the University of Copenhagen's Department of Geosciences and Nature Management.

Many animal species use social information - from conspecifics or other species - to inform their behavioral choices, for example where to look for food or build a nest. In a recent study, ornithologists have shown for the first time that the ability to use such information can depend on an individual's cognitive skills. In the collared flycatcher, females that mastered a learning task faster were more likely to copy the nest site choices of great and blue tits in the same area.

HOUSTON - (Dec. 22, 2020) - Bigger is not always better, but here's something that starts small and gets better as it gets bigger.

Just light it up and see.

A team led by Rice University chemists Christy Landes and Stephan Link, both associated with the Smalley-Curl Institute, have made hybrid particles that combine the unbeatable light-harvesting properties of plasmonic nanoparticles with the flexibility of catalytic polymer coatings. Their work could help power long-pursued plasmonic applications in electronics, imaging, sensing and medicine.

In what has the potential to significantly change how Corona patients are being treated and the severity of the disease, research spearheaded at Jerusalem's Hebrew University gathered early clinical evidence demonstrating the efficacy of an existing drug in treating COVID-19.
