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.
A new NHS study found that music therapy can be more effective than medication in soothing dementia patients in some cases, offering a gentler, more human approach to care.
Join us as we journey beyond the birth of the universe to unravel the mysteries of what might have preceded the Big Bang—and whether time itself had a beginning.

Physicist and fusion researcher Eric Lerner presents a sweeping critique of the Big Bang theory and the standard model of cosmology at Demysticon 25. He builds on the foundations of plasma physics and the work of Nobel laureate Hannes Alfvén to outline an alternative cosmological framework rooted in known physical laws—gravity, nuclear fusion, and electromagnetic plasma behavior—rather than hypothetical concepts like dark matter, dark energy, or cosmic inflation. He explores how filamentary plasma structures may account for galaxy formation, how fusion research using dense plasma focus devices parallels cosmic processes, and how the cosmic microwave background may not be relic radiation from a singular origin. Merging astrophysics, plasma cosmology, and energy research, this talk reframes the origin and structure of the universe—and calls into question the prevailing narratives at the heart of modern theoretical physics.

When a drummer hits a drum, the surface vibrates and creates sound—a signal we recognize as music. But once those vibrations stop, the signal disappears. Now imagine a drumhead that’s incredibly thin, only about 10 millimeters wide, and covered in tiny triangular holes. Scientists have created exactly that, and it does something extraordinary.
Researchers at the Niels Bohr Institute in Copenhagen, working with teams from the University of Konstanz and ETH Zurich, discovered that vibrations can travel through this miniature membrane with barely any energy loss. In fact, the vibrations move more cleanly than signals in even the most advanced electronic circuits. This breakthrough, recently published in Nature, opens up new possibilities for how we transmit sound and information, especially in the race toward powerful new quantum technologies.

My name is Artem, I’m a graduate student at NYU Center for Neural Science and researcher at Flatiron Institute. In this video we explore a recent study published in Science, which revealed that different compartments of pyramidal neurons (apical vs basal dendrites) use different plasticity rules for learning.
