Q&A: Elephants use the tips of their trunks to grasp things with great precision—how this can help robotic design?
2024-06-23 22:02:31
An elephant uses its trunk for eating, drinking water, communicating, exploring the environment, social behavior, and making and using tools. The trunk, which contains six muscle groups, is not only very strong—it can uproot a tree—but can be used with great precision. Elephants use a number of techniques to grasp objects, including suction, pinching with the two "fingers" at the tip of the trunk and wrapping the trunk around the object.
Beyond Nvidia: the search for AI's next breakthrough
2024-06-23 18:58:05
For a few days, AI chip juggernaut Nvidia sat on the throne as the world's biggest company, but behind its staggering success are questions on whether new entrants can stake a claim to the artificial intelligence bonanza.
Emotions may matter more than facts in shaping individual support for renewable energy, new study shows
2024-06-22 14:06:16
It seems like energy policies are constantly making headlines these days. Should Canada "axe the tax?" Is it time to end the tax breaks to Canadian fossil fuel companies and invest in renewable energy? Are electric vehicles a good investment? Should governments put the brakes on solar panels and wind turbines?
Scientists achieve 20% efficiency in organic solar cells with new molecular design
2024-06-21 18:30:43
To make organic solar cells (OSC) competitive, the light-absorbing molecules should simultaneously satisfy multiple key requirements, including a weak-absorption charge transfer state, a high dielectric constant, suitable surface energy and proper crystallinity.
New perovskite-based anode material achieves high efficiency at low and medium temperatures
2024-06-21 18:30:43
Amidst the ongoing energy and climate crises, the stakes have never been higher. We are pressed for time to find better ways of producing clean energy to replace fossil fuels. Thus far, fuel cells appear to be one of the most promising research directions. These electrochemical devices can produce electricity directly from chemical reactions, which can be tailored to be environmentally friendly in terms of their reactants and outputs.
Researchers 'crack the code' for quelling electromagnetic interference
2024-06-21 17:41:42
Florida Atlantic Center for Connected Autonomy and Artificial Intelligence (CA-AI.fau.edu) researchers have "cracked the code" on interference when machines need to talk with each other—and people.

A U.K. university spin-out has developed a bacteria-powered battery that harvests energy from microorganisms in the soil to recharge itself, with a prototype already rolled out in Brazil.
Model combines physical parameters and machine learning to predict storm tides
2024-06-21 17:41:41
Predicting extreme events is essential to the preparation and protection of vulnerable regions, especially at a time of climate change. The city of Santos on the coast of São Paulo state (Brazil) is Latin America's largest port and has been the focus for significant case studies, not least because of the storm surges that threaten its infrastructure and the local ecosystems.
