Neuroscientists have figured out how to reconstruct a song by decoding the brain signals of someone listening to it. A team from the University of California, Berkeley, reproduced Pink Floyd’s song ‘Another Bring in the Wall, Part 1’, after placing electrodes on the brains of patients and playing the music as they underwent epilepsy surgery. Analysis of the brain activity allowed the neuroscientists to create the song’s rhythm, as well as pick out understandable lines like “All in all it’s just another brick in the wall”. Scientists have previously used similar brain-reading techniques in an attempt to decipher speech from thoughts, but this is the first ever time that a recognisable song has been reconstructed from brain recordings. “It’s a wonderful result. One of the things for me about music is it has prosody and emotional content. As this whole field of brain machine interfaces progresses, this gives you a way to add musicality to future brain implants for people who need it, someone who’s got ALS or some other disabling neurological or developmental disorder compromising speech output,” said Robert Knight, a neurologist and UC Berkeley professor of psychology in the Helen Wills Neuroscience Institute who conducted the research. “It gives you an ability to decode not only the linguistic content, but some of the prosodic content of speech, some of the affect. I think that’s what we’ve really begun to crack the code on.” It is a significant development for brain-computer interface technology, which aims to connect humans to machines in order to fix neurological disorders or even add new abilities. Elon Musk claims that future versions of his Neuralink device will allow wearers to stream music directly to their brain, as well as cure depression and addiction by “retraining” certain parts of the brain. The scientists behind the latest research claim that advances in brain recording techniques could soon allow them to make detailed recordings using non-invasive techniques like ultra-sensitive electrodes attached to the scalp. “Non-invasive techniques are just not accurate enough today,” said postdoctoral fellow Ludovic Bellier, who was part of the research team. “Let’s hope, for patients, that in the future we could, from just electrodes placed outside on the skull, read activity from deeper regions of the brain with a good signal quality. But we are far from there.” The research was detailed in a study, titled ‘Music can be reconstructed from human auditory cortex activity using nonlinear decoding models’, published in the scientific journal PLoS Biology.

Black holes are the most confusing things out there in the universe and no-one really knows what they are – at least, that’s our very basic grasp of it. Now, though, a new study has posited a theory that black holes are structures created by unseen cosmic dimensions - or topological stars. And just to make it a little more confusing, these topological stars exist purely in the hypothetical realms of mathematics. Researchers at Johns Hopkins University have been exploring string theory, which posits that particles in the universe are actually tied to extra (hidden) dimensions through vibrating strings.

The study finds that topological stars would appear “remarkably similar to black holes in apparent size and scattering properties, while being smooth and horizonless”. The study, which was published in Physical Review D, found that these stars which until now have only existed in hypothetical form, look an awful lot like the black holes out in the universe. “String theory is a theory that reconciles quantum physics and gravity into a quantum gravity theory,” study leader Pierre Heidmann said. Speaking to Motherboard, he said: “Usually when you have a new theory like that, you have new degrees of freedom that come with it, and you can try to see what new fundamental objects can arise from that.” Co-author of the study Ibrahima Bah added: “It’s an interesting question to ask: Are there things other than a black hole [that] will give you a hint about what new physics could look like?” “But before you get there, you need to know how to tell whether you have a black hole or not, and to do that you have some prototype examples of things that are not black holes to be able to compare." As ever, black holes remain the most mysterious, and the most fascinating things out there. Have your say in our news democracy.

Scientists have figured out what the sun sound like - because yes, it makes a racket. By recording acoustical pressure waves in the sun, using an instrument called the Michelson Doppler Imager, solar physicists from Stanford University have determined the solar surface noise of the sun and it turns out it is pretty loud. If the sounds, which are apparently like 'screaming sirens' were able to pass through space, it would be 100 decibels by the time it reached us here on Earth, according to the American Academy of Audiology. This equals out to tens of thousands of watts of energy generated per metre on the sun, or 10x to the 100x the power of speakers at a rock concert.. Sign up to our free Indy100 weekly newsletter However, humans on Earth are unable to hear any of this because the sound waves emit at frequencies that are too low for the human ear to detect. The sun creates noise due to the constant flow of hot material on the surface and the sinking of cooled material towards the centre. Have your say in our news democracy.
