Un nuevo estudio científico ha resuelto un debate centenario al demostrar que el toque de un pianista puede, efectivamente, alterar el color tonal de las notas del piano. Los investigadores utilizaron sensores avanzados para capturar movimientos sutiles de las teclas a gran velocidad. Los hallazgos indican que estos movimientos producen diferencias audibles en el brillo, la pesantez y la claridad.

Investigadores dirigidos por el Dr. Shinichi Furuya, del NeuroPiano Institute y de los Sony Computer Science Laboratories, llevaron a cabo el estudio. Emplearon un sistema personalizado sin contacto llamado HackKey para rastrear las 88 teclas del piano a 1.000 fotogramas por segundo. Veinte pianistas de renombre internacional interpretaron notas con cualidades tonales contrastantes, tales como sonidos brillantes frente a oscuros, y ligeros frente a pesados.

Study finds infrasound can raise cortisol and irritability even when people can’t hear it

A small controlled experiment reported in Frontiers in Behavioral Neuroscience found that exposure to infrasound—ultra-low-frequency vibration below the range of human hearing—was associated with higher salivary cortisol and more negative mood ratings, even though participants could not reliably detect when the infrasound was present.

Samoyeds adjust howls to music pitch in new study

A study by researchers at Tufts University reveals that some Samoyeds alter the pitch of their howls in response to changes in music, suggesting an inherited vocal ability from wolf ancestors. The findings, published in Current Biology, indicate dogs can perceive and adapt to pitch without vocal learning. This may shed light on the evolutionary origins of human musicality.

Study explores quantum clocks ticking at multiple speeds

Physicists have published research proposing that a single clock could tick both faster and slower at the same time due to quantum effects. The work combines relativity and quantum mechanics in a novel way. Researchers say advances in atomic clock technology may soon allow the idea to be tested in the lab.

NYU physicists create sound-levitated time crystal breaking Newton's third law

24 de marzo de 2026 Reportado por IA

Physicists at New York University have developed a new type of time crystal using sound waves to suspend tiny styrofoam beads, resulting in nonreciprocal interactions that defy Newton's third law of motion. The compact, visible system oscillates in a steady rhythm and was detailed in Physical Review Letters. Researchers suggest potential applications in quantum computing and insights into biological rhythms.
