Um novo estudo científico resolveu um debate centenário ao mostrar que o toque de um pianista pode, de fato, alterar a cor tonal das notas de piano. Pesquisadores utilizaram sensores avançados para capturar movimentos sutis das teclas em alta velocidade. As descobertas indicam que esses movimentos produzem diferenças audíveis em brilho, peso e clareza.

Pesquisadores liderados pelo Dr. Shinichi Furuya, do NeuroPiano Institute e dos Sony Computer Science Laboratories, conduziram o estudo. Eles empregaram um sistema sem contato personalizado chamado HackKey para rastrear todas as 88 teclas do piano a 1.000 quadros por segundo. Vinte pianistas aclamados internacionalmente executaram notas com qualidades tonais contrastantes, como sons brilhantes versus sombrios e leves versus 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 março 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.
