The fascinating phenomenon of sonoluminescence, where light is produced when an underwater bubble is collapsed by a sound wave, has sparked a vibrant discussion. Despite being a subject of scientific research and debate, the exact mechanisms behind sonoluminescence are still not fully understood.

One user pointed out that this phenomenon is also known as sonoluminescence, which occurs when a small gas bubble in a liquid is collapsed by intense sound waves, emitting a short burst of light. This can happen in a laboratory setting using a device that generates and focuses sound waves into a liquid.

Several theories have been proposed to explain how the light is produced. The Hot Spot Theory suggests that the bubble’s collapse causes the gas inside to heat up to extremely high temperatures, possibly hot enough to ionize the gas and produce a plasma, which then emits light.

The University of Chicago Medicine is among the first 30 institutions in the country to offer tumor-infiltrating lymphocyte (TIL) therapy for advanced melanoma, immediately activating as an authorized treatment center after federal regulators approved the treatment on February 16, 2024.

Effortless, enjoyable productivity is a state of consciousness prized and sought after by people in business, the arts, research, education and anyone else who wants to produce a stream of creative ideas and products. That’s the flow, or the sense of being “in the zone.” A new neuroimaging study from Drexel University’s Creativity Research Lab is the first to reveal how the brain gets to the creative flow state.

The study is published in the journal Neuropsychologia.

The study isolated flow-related brain activity during a creative task: jazz improvisation. The findings reveal that the creative flow state involves two key factors: extensive experience, which leads to a network of brain areas specialized for generating the desired type of ideas, plus the release of control— letting go—to allow this network to work with little or no conscious supervision.

When listening to music, the human brain appears to be biased toward hearing and producing rhythms composed of simple integer ratios—for example, a series of four beats separated by equal time intervals (forming a 1:1:1 ratio).

However, the favored ratios can vary greatly between different societies, according to a large-scale study led by researchers at MIT and the Max Planck Institute for Empirical Aesthetics and carried out in 15 countries. The study included 39 groups of participants, many of whom came from societies whose traditional contains distinctive patterns of rhythm not found in Western music.

“Our study provides the clearest evidence yet for some degree of universality in music perception and cognition, in the sense that every single group of participants that was tested exhibits biases for integer ratios. It also provides a glimpse of the variation that can occur across cultures, which can be quite substantial,” says Nori Jacoby, the study’s lead author and a former MIT postdoc, who is now a research group leader at the Max Planck Institute for Empirical Aesthetics in Frankfurt, Germany.

India has waded into global AI debate by issuing an advisory that requires “significant” tech firms to get government permission before launching new models.

India’s Ministry of Electronics and IT issued the advisory to firms on Friday. The advisory — not published on public domain but a copy of which TechCrunch has reviewed — also asks tech firms to ensure that their services or products “do not permit any bias or discrimination or threaten the integrity of the electoral process.”

Though the ministry admits the advisory is not legally binding, India’s IT Deputy Minister Rajeev Chandrasekhar says the notice is “signalling that this is the future of regulation.” He adds: “We are doing it as an advisory today asking you to comply with it.”

Unitree is a publicly traded robot company with about $5 billion in market value. They have sped up their humanoid robot to human jogging speed of 3.3 meters per second. This is about 7.5 miles per hour. It would not tire so it would take 50 minutes to cover a 10 kilometer race with enough battery power.

It can lift boxes and climb and descend stairs. It was able to jump vertically.

They have hand attachments that currently do not have finger and grasping motions.

Researchers have developed a computer “worm” that can spread from one computer to another using generative AI, a warning sign that the tech could be used to develop dangerous malware in the near future — if it hasn’t already.

As Wired reports, the worm can attack AI-powered email assistants to obtain sensitive data from emails and blast out spam messages that infect other systems.

“It basically means that now you have the ability to conduct or to perform a new kind of cyberattack that hasn’t been seen before,” Cornell Tech researcher Ben Nassi, coauthor of a yet-to-be-peer-reviewed paper about the work, told Wired.
