A groundbreaking study reveals dopamine’s crucial role in controlling movement sequence lengths, shedding light on potential treatments for Parkinson’s Disease symptoms beyond traditional reward and pleasure associations. Credit: SciTechDaily.comDopamine’s influence extends to regulating movement lengths, offering new therapeutic targets for Parkinson’s Disease.Dopamine, a chemical messenger in the brain, is mostly known for its role in how we experience pleasure and reward. However, new research from the Champalimaud…

It’s a clear day in Zermatt, a remote Swiss town anchored in a sharp valley under the gaze of the Matterhorn. We’ve taken off from Air Zermatt, home to some of the best high-altitude rescue pilots in the world. I’d flown in helicopters before but never piloted one. And this location was hardly a beginner course.“Are you ready to take the reins?” the controller asks.“Um, I think . . .?” I said nervously.“In three, two, one . . .” And with that, the full power of the craft shifts to my command. The controls are exquisitely…

An elephant, Loxodonta africana, throws dirt into the air in the tall grass of the savanna. Credit: Jeffrey T. KerbyA new meta-analysis across six continents establishes that large wild herbivores affect ecosystems in numerous important ways, from soils to vegetation to smaller animals, and promote ecosystem variability.For millions of years, a variety of large herbivores, or megafauna, influenced terrestrial ecosystems. Among many others, these included elephants in Europe, giant wombats in Australia, and ground sloths…

At the University of Rostock, researchers have combined PT symmetry with topology in photonic chips, challenging previous beliefs about open systems and topological insulators, and paving the way for innovative technological applications. Credit: SciTechDaily.comGroundbreaking research merges PT symmetry with topology, offering new insights into open systems and the potential for advanced technological circuits.Whether describing the orbits of planets or the inner workings of the atom, a key paradigm in physics is the…

In 2020, as the Indian startup scene began to boom, Reshbha Munjal, a Delhi-based angel investor, decided to shift her investment focus. Until then, she had put her money in stocks and mutual funds. After seeing the rise of companies like Flipkart and Ola, she was convinced that she should invest in private markets. “I saw an opportunity to achieve scale in the private market and to invest in ideas that aren’t accessible in public markets,” she says.Elevate Your Tech Prowess with High-Value Skill CoursesOffering…
