Researchers use laser paintbrush to create miniature masterpieces

Posted by in category: media & arts

Researchers are blurring the lines between science and art by showing how a laser can be used to create artistic masterpieces in a way that mirrors classical paints and brushes. The new technique not only creates paint-like strokes of color on metal but also offers a way to change or erase colors.

“We developed a way to use a laser to create localized color on a metallic canvas using a technique that heats the to the point where it evaporates,” said research team leader Vadim Veiko from ITMO University in Russia. “With this approach, an artist can create miniature art that conveys complex meaning not only through shape and color but also through various laser-induced microstructures on the surface.”

In Optica, The Optica l Society’s (OSA) journal, Veiko and colleagues show that their new laser tools can be used to create unique colorful paintings, including a miniature version of Van Gogh’s painting “The Starry Night.”

Music-selective neural populations arise without musical training

Posted by in categories: media & arts, neuroscience

Recent work has shown that human auditory cortex contains neural populations anterior and posterior to primary auditory cortex that respond selectively to music. However, it is unknown how this selectivity for music arises. To test whether musical training is necessary, we measured fMRI responses to 192 natural sounds in 10 people with almost no musical training. When voxel responses were decomposed into underlying components, this group exhibited a music-selective component that was very similar in response profile and anatomical distribution to that previously seen in individuals with moderate musical training. We also found that musical genres that were less familiar to our participants (e.g., Balinese gamelan) produced strong responses within the music component, as did drum clips with rhythm but little melody, suggesting that these neural populations are broadly responsive to music as a whole. Our findings demonstrate that the signature properties of neural music selectivity do not require musical training to develop, showing that the music-selective neural populations are a fundamental and widespread property of the human brain.

Why the Brain Enjoys Music

Posted by in categories: media & arts, neuroscience

Summary: Interaction between auditory areas of the brain and the reward system drive pleasure when we listen to music.

Communication between the brain’s auditory and reward circuits is the reason why humans find music rewarding, according to new research published in Journal of Neuroscience.

New Video Shows Beverly Hills Cops Playing Beatles to Trigger Instagram Copyright Filter

Posted by in category: media & arts

In comments to City Council last year about APD’s intellectual property enforcement grant, I warned council that one thing I was concerned about was that APD might try to confiscate/remove activist videos by issuing takedown notices for copyrighted music playing in the background of the videos. Looks like I was right to be worried.


In at least three cases, Beverly Hills Cops have started playing music seemingly to prevent themselves from being filmed by an activist.

Inspired by the forces behind evolution, artist and tool designer Joel Simon programmed a network of computers to blend and “breed” together images over and over using users’ preferences as its guide. Although thousands of users, breeding millions of bizarre and beautiful images, Joel’s goal was more conceptual: He wanted to see if the system could evolve art and what types of forms might emerge from the process.

Kernel the most powerful neural interface in the world

Posted by in categories: biotech/medical, media & arts, neuroscience, singularity, transhumanism

Flux is unmatched in the quality, speed and quantity of neural activity that can record non-invasively and in real time.
So far, all types of data that could be acquired directly from the human brain had serious limitations. To get the best hemodynamic or electric data, for example, the person and their brain needed to be almost perfectly immovable, usually by confinement in noisy and claustrophobic environments. And if the person was able to move freely and, of course, data quality quickly dropped until it was pointless.
With the Flux, you will be able to:
Step into a natural environment, put a helmet on your head and observe the real-time brain activity at the top speed your neurons are shooting;
Talk, gesture and move naturally;
Participate in a video conference, daydream, listen to music or read a book;
Access your brain activity from the most electrophysiological sensor channels from all regions of the cortex.
These capabilities open up new stimulating opportunities for understanding how and why the brain functions.
In October 2020, Flow was announced, a full-coverage TD-FNIRS system, which is the first high-quality scalable brain imaging system of its kind and analyses the hemodynamic signs generated by the use of oxygen in the brain, a good proxy for neural activity Together, Flow and Flux capture two signs of the highest quality and most significant one can capture on the brain in a non-invasive way: blood oxygenation and direct neural activity. There are advantages and disadvantages to what each of these technologies reveals about the mysteries of the brain — together, however, Kernel Flux and Flow combine into the richest neural data sets in history, collected at a record speed.
A new era is here. One where we will be reintroduced ourselves and each other in unique ways. With powers to advance to a new border.
