When artificial intelligence systems start getting creative, they can create great things – and scary ones. Take, for instance, an AI program that let web users compose music along with a virtual Johann Sebastian Bach by entering notes into a program that generates Bach-like harmonies to match them.

Run by Google, the app drew great praise for being groundbreaking and fun to play with. It also attracted criticism, and raised concerns about AI’s dangers.

My study of how emerging technologies affect people’s lives has taught me that the problems go beyond the admittedly large concern about whether algorithms can really create music or art in general. Some complaints seemed small, but really weren’t, like observations that Google’s AI was breaking basic rules of music composition.

White Rabbit
Recorded Live: 11/8/1975 — Winterland — San Francisco, CA
More Jefferson Starship at Music Vault: http://www.musicvault.com

Personnel:
Grace Slick — vocals
Paul Kantner — vocals, guitar
Marty Balin — vocals, percussion
David Frieberg — keyboards, bass, vocals.
Craig Chaquico — lead guitar
Pete Sears — bass, piano
Johnny Barbata — drums, vocals (on track #4)

Summary:
Recorded after the monumentally successful Red Octopus album release, but prior to 1976’s Spitfire album, this Jefferson Starship concert captures the band performing a diverse set before a hometown audience. With singer Marty Balin back in the fold, the group again contained the three primary vocalists from the Jefferson Airplane, now supported by vocalist, keyboardist, part-time bassist, and ex-Quicksilver Messenger Service member David Frieberg; the young guitar prodigy Craig Chaquico; and the superb rhythm section of bassist/pianist Pete Sears and drummer Johnny Barbata. The group was riding high on the multi-platinum Red Octopus album and was arguably at a new peak of popularity.

This set is not only represented by material from the early Jefferson Starship albums and a couple of Jefferson Airplane classics, but interestingly features live performances of material from Grace Slick’s first solo album plus two of the best tracks Marty Balin recorded with his post-Jefferson Airplane project, Bodacious D F.

Lasers have been used to send targeted, quiet messages to someone from several meters away, in a way that no one nearby would be able to hear.

How it works: To send the messages, researchers from MIT relied upon the photoacoustic effect, in which water vapor in the air absorbs light and forms sound waves. The researchers used a laser beam to transmit a sound at 60 decibels (roughly the volume of background music or conversation in a restaurant) to a target person who was standing 2.5 meters away.

A second technique modulated the power of the laser beam to encode a message, which produced a quieter but clearer result. The team used it to beam music, recorded speech, and various tones, all at conversational volume. “This can work even in relatively dry conditions because there is almost always a little water in the air, especially around people,” team leader Charles M. Wynn said in a press release. Details of the research were published in Optics Letters.

Canada’s billionaire power couple, Gerald Schwartz and Heather Reisman, have donated C$100 million ($75 million) to the University of Toronto for an artificial intelligence complex.

The gift, from the duo behind private-equity firm Onex Corp. and Indigo Books & Music Inc., is the largest in the university’s history and biggest for Canada’s technology sector, said the academic institution. It will be used to build the Schwartz Reisman Innovation Centre starting this year.

“You’ve seen companies like Uber and Google and so many others starting to make real commitments to Toronto, and this is drawing people from around the world to come to Toronto to be part of this,” Schwartz, Onex’s founder and chief executive officer, said in an interview at Indigo’s headquarters in the city. “That legacy is going to last for a long time.”

Boston University researchers, Xin Zhang, a professor at the College of Engineering, and Reza Ghaffarivardavagh, a Ph.D. student in the Department of Mechanical Engineering, released a paper in Physical Review B demonstrating it’s possible to silence noise using an open, ringlike structure, created to mathematically perfect specifications, for cutting out sounds while maintaining airflow.

“Today’s barriers are literally thick heavy walls,” says Ghaffarivardavagh. Although noise-mitigating barricades, called sound baffles, can help drown out the whoosh of rush hour traffic or contain the symphony of music within concert hall walls, they are a clunky approach not well suited to situations where airflow is also critical. Imagine barricading a jet engine’s exhaust vent—the plane would never leave the ground. Instead, workers on the tarmac wear earplugs to protect their hearing from the deafening roar.

Ghaffarivardavagh and Zhang let mathematics—a shared passion that has buoyed both of their engineering careers and made them well-suited research partners—guide them toward a workable design for what the acoustic metamaterial would look like.

Death is the one thing that’s guaranteed in today’s uncertain world, but now a new start-up called Humai thinks it might be able to get rid of that inconvenient problem for us too, by promising to transfer people’s consciousness into a new, artificial body.

If it sounds like science fiction, and that’s because it still is, with none of the technology required for Humai’s business plan currently up and running. But that’s not deterring the company’s CEO, Josh Bocanegra, who says his team will resurrect their first human within 30 years.

So how do you go about transferring someone’s consciousness to another robot body? As Humai explains on their website (which comes complete with new-age backing music):

A new study has found that dopamine — a neurotransmitter that plays an important role in our cognitive, emotional, and behavioral functioning — plays a direct role in the reward experience induced by music. The new findings have been published in the Proceedings of the National Academy of Sciences.

“In everyday life, humans regularly seek participation in highly complex and pleasurable experiences such as music listening, singing, or playing, that do not seem to have any specific survival advantage. Understanding how the brain translates a structured sequence of sounds, such as music, into a pleasant and rewarding experience is thus a challenging and fascinating question,” said study author Laura Ferreri, an associate professor in cognitive psychology at Lyon University.

“In the scientific literature, there was a lack of direct evidence showing that dopamine function is causally related to music-evoked pleasure. Therefore in this study, through a pharmacological approach, we wanted to investigate whether dopamine, which plays a major role in regulating pleasure experiences and motivation to engage in certain behaviors, plays a direct role in the experience of pleasure induced by music.”
