The tone and tuning of musical instruments has the power to manipulate our appreciation of harmony, new research shows. The findings challenge centuries of Western music theory and encourage greater experimentation with instruments from different cultures.

According to the Ancient Greek philosopher Pythagoras, ‘consonance’—a pleasant-sounding combination of notes—is produced by special relationships between simple numbers such as 3 and 4. More recently, scholars have tried to find psychological explanations, but these ‘integer ratios’ are still credited with making a chord sound beautiful, and deviation from them is thought to make music ‘dissonant,’ unpleasant sounding.

But researchers from the University of Cambridge, Princeton and the Max Planck Institute for Empirical Aesthetics, have now discovered two key ways in which Pythagoras was wrong.

While Pika’s AI generated videos remain arguably lower quality and less “realistic” than the ones shown off by OpenAI’s Sora or even another rival AI video generation startup, Runway, the addition of the new Lip Sync feature puts it ahead of both in offering capabilities disruptive to traditional filmmaking software.

With Lip Sync, Pika is addressing one of the last remaining barriers to AI being useful for creating longer narrative films. Most other leading AI video generators don’t yet currently offer a similar feature natively.

Google Pay, the digital payment app for desktop, mobile apps, and in stores, was pretty much phased out by the introduction of Google Wallet in 2022. Google Wallet, which is a mobile app for Android users, is used five times more than Google Pay, according to the announcement. Since Wallet can also house credit cards for tap-to-pay, as well as digital IDs, and public transit passes, it’s proven to be the more useful alternative.

It’s somewhat typical for Google to launch products only to shut them down or roll them into other products after a few years due to lack of demand or commercial interest. The Google graveyard includes Jamboard, its cloud gaming service Stadia, and Google Play Music. So this is just one of many Google products to bite the dust. But Google Pay users won’t be left stranded.

If you’re a Google Pay user, you can still use the U.S. version of the app until June 4. But you can still transfer funds from your account into your bank account through the Google Pay website after June 4. After that, Google Pay users will no longer be able to send, request, or transfer money through the app.

Summary: Researchers developed an innovated a technique to convert complex neuroimaging data into audiovisual formats. By transforming brain activity and blood flow data from behaviors like running or grooming in mice into synchronized piano and violin sounds, accompanied by video, they offer an intuitive approach to explore the brain’s intricate workings.

This method not only makes it easier to identify patterns in large datasets but also enhances the understanding of the dynamic relationship between neuronal activity and behavior. The toolkit represents a significant step forward in neuroscientific research, enabling scientists to intuitively screen and interpret vast amounts of brain data.

Summary: Researchers unlocked how the brain processes melodies, creating a detailed map of auditory cortex activity. Their study reveals that the brain engages in dual tasks when hearing music: tracking pitch with neurons used for speech and predicting future notes with music-specific neurons.

This breakthrough clarifies the longstanding mystery of melody perception, demonstrating that some neural processes for music and speech are shared, while others are uniquely musical. The discovery enhances our understanding of the brain’s complex response to music and opens avenues for exploring music’s emotional and therapeutic impacts.

A new study by researchers at UC San Francisco provides new insight into how the brain processes musical melodies. Through precise mapping of the cerebral cortex, the study uncovered that our brains process music by not only discerning pitch and the direction of pitch changes but also by predicting the sequence of upcoming notes, each task managed by distinct sets of neurons. The findings have been published in Science Advances.

Previous research had established that our brains possess specialized mechanisms for processing speech sounds, particularly in recognizing pitch changes that convey meaning and emotion. The researchers hypothesized that a similar, perhaps specialized, set of neurons might exist for music, dedicated to predicting the sequence of notes in a melody, akin to how certain neurons predict speech sounds.

“Music is both uniquely human and universally human. Studying the neuroscience of music can therefore reveal something fundamental about what it means to be human,” said lead author Narayan Sankaran, a postdoctoral fellow in the Kavli Center for Ethics, Science, and the Public at UC Berkeley, who conducted the study while a researcher in the lab of UCSF’s Edward Chang.

Listening to electronic music makes neurons in our brain fire in time with the beat, which appears to alter our reaction time and sense of unity.
