Astronomers Say Black Holes Might Be Secret Space Portals

Imagine staring at a black hole… and realizing it might actually be a doorway. Scientists now think some black holes could be wormholes — real portals through space and time. The craziest part? They look so much like black holes that we might have been seeing them for years without knowing it. If that’s true, they could lead to faraway parts of the universe… or somewhere even stranger. In this video, we’ll explore what that means, the science behind it, and the mind-bending possibilities it opens up. Get ready — space just got a whole lot weirder.

Robotic drummer gradually acquires human-like behaviors

Humanoid robots, robots with a human-like body structure, have so far been primarily tested on manual tasks that entail supporting humans in their daily activities, such as carrying objects, collecting samples in hazardous environments, supporting older adults or acting as physical therapy assistants. In contrast, their potential for completing expressive physical tasks rooted in creative disciplines, such as playing an instrument or participating in performance arts, remains largely unexplored.

Researchers at SUPSI, IDSIA and Politecnico di Milano recently introduced Robot Drummer, a new humanoid robot that can play the drums both accurately and expressively, supported by a reinforcement learning algorithm. This robot, presented in a paper published on the arXiv preprint server, was found to gradually acquire human-like behaviors, including movements that are often performed by drummers.

“The idea for Robot Drummer actually emerged from a spontaneous conversation over coffee with my co-author, Loris Roveda,” Asad Ali Shahid, first author of the paper, told Tech Xplore. “We were discussing how humanoid robots have become increasingly capable at a wide range of tasks, but rarely engage in creative and expressive domains. That raised a fascinating question: what if a humanoid robot could take on a creative role, like performing music? Drumming seemed like a perfect frontier, as it’s rhythmic, physical, and requires rapid coordination across limbs.”

Computational musicology: Tracking the changing sound of bands

Coldplay, Radiohead or R.E.M.—which band has changed their music the most over the years? Professor Nick Collins from Durham University Department of Music has used a computer to try and find the answer to this by analyzing rhythm, harmony, and sound quality (known as timbre).

Want to boost your brain as you age? Music might be the answer

Long-term musical training may mitigate the age-related decline in speech perception by enhancing cognitive reserve, according to a study published in PLOS Biology by Claude Alain from the Baycrest Academy for Research and Education, Canada, and Yi Du from the Chinese Academy of Sciences.

Normal aging is typically associated with declines in sensory and cognitive functions. These age-related changes in perception and cognition are often accompanied by increased neural activity and functional connectivity—the statistical dependence of activity between different brain regions—in widely distributed neural networks.

The recruitment of neural activity and strengthening of functional connectivity are thought to reflect a compensatory strategy employed by older adults to maintain optimal cognitive performance.
