Flexible Loudspeaker Made of Nanowires Will Stick to Your Skin and Play Music

Posted by in categories: media & arts, nanotechnology

Now researchers at Ulsan National Institute of Science and Technology (UNIST) in South Korea have made a nanomembrane out of silver nanowires to serve as flexible loudspeakers or microphones. The researchers even went so far as to demonstrate their nanomembrane by making it into a loudspeaker that could be attached to skin and used it to play the final movement of a violin concerto—namely, La Campanella by Niccolo Paganini.

Researchers in South Korea made a tiny loudspeaker, and then used it to play a violin concerto.

A system to generate new song lyrics that match the style of specific artists

Posted by in categories: media & arts, robotics/AI

Researchers at the University of Waterloo, Canada, have recently developed a system for generating song lyrics that match the style of particular music artists. Their approach, outlined in a paper pre-published on arXiv, uses a variational autoencoder (VAE) with artist embeddings and a CNN classifier trained to predict artists from MEL spectrograms of their song clips.

“The motivation for this project came from my personal interest,” Olga Vechtomova, one of the researchers who carried out the study, told TechXplore. “Music is a passion of mine, and I was curious about whether a machine can generate lines that sound like the lyrics of my favourite music artists. While working on text generative models, my research group found that can generate some impressive lines of text. The natural next step for us was to explore whether a machine could learn the ‘essence’ of a specific music artist’s lyrical style, including choice of words, themes and sentence structure, to generate novel lyrics lines that sound like the artist in question.”

The system developed by Vechtomova and her colleagues is based on a neural network model called variational autoencoder (VAE), which can learn by reconstructing original lines of text. In their study, the researchers trained their model to generate any number of new, diverse and coherent lyric lines.

Probably my biggest regret when I made the Hubble Deep Field in 3D video is saying the phrase “these galaxies are racing away from us, in some cases faster than light”.

Meet the People Trying to Live Long Enough to Live Forever

Posted by in categories: life extension, media & arts

For the most serious devotees, immortality-seeking is a full-time commitment to keeping abreast of the latest innovations—they speak of these “modalities” with the same reverence a Christian would of a blessing. A $250 billion industry of antiaging products and services is there for the collection—and many of their offerings are for sale at RAADfest.

What Treasures Were Lost in the Destruction of the Great Musaeum of Alexandria?

Posted by in categories: media & arts, neuroscience

The city he described did not exist for much longer. A bishop soon destroyed the heritage of many generations of ancient minds in the name of a new faith. In 391 AD, the beautiful temple of wisdom was ruined. There is no evidence of the existence of the library after that date, but it seems that the people of Alexandria, the legendary philosophers, scientists, and their supporters saved some of the books. However, in 642 AD, when the city was captured by Muslims, they burned all the books not related to Islam that they found in public places.

The monumental Musaeum of Alexandria was famous for its legendary library. The tragic story of the building’s destruction continues to be a painful one for people who love ancient history and literature. So what treasures were lost in its devastating fire?

The Musaeum, or Mouseion, was a home to art, music, poetry, and philosophy. It is extremely difficult to find out exactly what was located on the shelves of the library, but generations of passionate researchers have created some possible lists of the lost scrolls’ authors.

China’s biggest streaming-music service reveals the details for its US IPO

Posted by in categories: entertainment, media & arts

  • Tencent Music on Monday set the price for its US initial public offering after global markets got a boost from a truce in the US-and-China trade war.
  • The company said American Depository Receipts will price between $13 and $15, helping it raise as much as $1.2 billion.
  • The IPO was initially scheduled for October 18, but was postponed due to stock-market volatility.
  • Monday’s filing comes after President Donald Trump agreed to postpone new tariffs on Chinese imports by 90 days and Chinese President Xi Jinping agreed to buy a substantial amount of US goods and name Fentanyl a controlled substance.

Tencent Music Entertainment filed with the Securities and Exchange Commission on Monday to set the price for its US initial public offering — one day after President Donald Trump and Chinese President Xi Jinping announced a truce in the trade war between the US and China.

The China-based streaming-music service backed by tech giant Tencent said the offering price will be in the range of $13 and $15 per American Depository Receipt, helping it raise as much as $1.2 billion.

Artificial intelligence faithfully recreates paintings with a 3D printer

Posted by in categories: 3D printing, media & arts, robotics/AI

Replicas of famous paintings are routinely created with printers that use only four inks – cyan, magenta, yellow, and black. RePaint, a new technique developed at MIT, combines artificial intelligence, 3D printing, and a rich 10-ink palette for much more faithful results in any lighting condition.

A ‘party drug’ with potential to be the next blockbuster antidepressant is edging closer to the mainstream, but it could set you back $9,000

Posted by in categories: media & arts, neuroscience

  • Once dismissed as a “party drug,” ketamine is emerging as a potential alternative treatment for depression.
  • A growing list of academic medical centers now offer the drug, including Columbia University, which began offering ketamine to patients with severe depression this fall.
  • Ketamine works differently from common antidepressants like Celexa or Prozac and has been called “the most important discovery in half a century.”
  • Pharmaceutical companies, including Allergan and Johnson & Johnson, are also working on developing blockbuster antidepressants inspired by ketamine.

Ketamine, a drug once associated with raucous parties, bright lights, and loud music, is increasingly being embraced as an alternative depression treatment for the millions of patients who don’t get better after trying traditional medications.

The latest provider of the treatment is Columbia University, one of the nation’s largest academic medical centers.

Paralyzed individuals successfully use brain waves to operate tablet computers

Posted by in categories: biotech/medical, media & arts, robotics/AI

In a collaborative study presented by scientists primarily affiliated with Stanford and Brown Universities, participants suffering from significant paralysis were successfully able to use non-modified applications on an Android tablet using their brain waves. In previous studies, “point-and-click” computer functionality interpreted from these kinds of signals has been accomplished, but the applications available to participants was limited to software and devices that had been specialized and personalized for users’ specific needs. This study has demonstrated technology that overcomes this limitation and enables access to the full range of software available to non-disabled users. Participants enjoyed applications previously unavailable to them such as streaming music services and a piano keyboard player.

To accomplish the study’s objectives, scientists capitalized and combined existing technologies for their unique end. Brain waves from participants’ brain implants were sent to a commercially available recording system and then processed and decoded by an existing real-time interpreter software. The decoded data was then transmitted to a Bluetooth interface configured as a wireless mouse which was paired to an Android tablet. While the steps to accomplish the task at hand are many, the result somewhat resembles telepathy but largely resembles greater accessibility for the disabled.
