Why watermarking AI-generated content won’t guarantee trust online

Posted by in categories: finance, government, military, robotics/AI

The need for transparency around AI-generated content is clear, but the value of measures like watermarks is not.

A few miles away, White House aides and reporters scrambled to figure out whether a viral online image of the exploding building was in fact real.

It wasn’t. It was AI-generated. Yet government officials, journalists, and tech companies were unable to take action before the image had real impact. It not only caused confusion but led to a dip in financial markets.

After 25 years of hype, embryonic stem cells are still waiting for their moment

Posted by in categories: biotech/medical, neuroscience

Research roadblocks and political debates have delayed progress—but scientists are inching closer to delivering a cure.

Twenty-five years ago, in 1998, researchers in Wisconsin isolated powerful stem cells from human embryos. It was a fundamental breakthrough for biology, since these cells are the starting point for human bodies and have the capacity to turn into any other type of cell—heart cells, neurons, you name it.

National Geographic would later summarize the incredible promise: “the dream is to launch a medical revolution in which ailing organs and tissues might be repaired” with living replacements. It was the dawn of a new era. A holy grail. Pick your favorite cliché—they all got… More.

What the Finance Industry Tells Us About the Future of AI

Posted by in categories: business, employment, finance, information science, robotics/AI

Summary.


What will artificial intelligence do to industries and jobs? For a preview, look to the finance industry which has been incorporating data and algorithms for a long time, and which is always a canary in the coal mine for new technology. The experience of finance suggests that AI will transform some industries (sometimes very quickly) and that it will especially benefit larger players. But it may not leave the overall system better off.

Amazon’s Project Kuiper satellites will fly on the new Vulcan Centaur rocket in early 2023

Posted by in categories: Elon Musk, internet, satellites

Jeff Bezos’ e-commerce giant is set to rival Elon Musk’s Starlink service with its 3,200-internet satellite mega-constellation.

Amazon has announced it will now deploy its two Project Kuiper prototype satellites aboard a United Launch Alliance (ULA) Atlas V rocket this fall.

LLMs like GPT and Bard can be manipulated and hypnotized

Posted by in categories: existential risks, finance, internet, robotics/AI

Hypnotized LLMs can help leak confidential financial information, generate malicious code and even cross red lights.

Tech pundits worldwide have been fluctuating between marking artificial intelligence as the end of all of humanity and calling it the most significant thing humans have ever touched since the internet.

We are in a phase where we are unsure what the AI Pandora’s box will reveal. Are we heading for doomsday or utopia?

Google and Universal Music partner up to develop AI music tool

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

The AI tool allows people to create songs using the voices of various artists. What will this do to the music industry?

Months after an outburst over AI-engineered songs that used the voice of artists, it seems like the world’s largest record label – Universal Music Group (UMG) – is getting on board to ride the AI wave before it washes out the company.

In collaboration with Google, UMG will soon develop a tool allowing fans to create AI-generated music using musicians’ voices, reported Financial Times. The deal involves paying copyright holders their share in using their melody and allows the artists a choice to opt in.

After 15 years, pulsar timing yields evidence of cosmic background gravitational waves

Posted by in categories: physics, space

The universe is humming with gravitational radiation—a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it.

That is the conclusion of several groups of researchers from around the world who simultaneously published a slew of journal articles in June describing more than 15 years of observations of millisecond pulsars within our corner of the Milky Way galaxy. At least one group—the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) collaboration—has found compelling evidence that the precise rhythms of these pulsars are affected by the stretching and squeezing of spacetime by these long-wavelength .

“This is key evidence for gravitational waves at very low frequencies,” says Vanderbilt University’s Stephen Taylor, who co-led the search and is the current chair of the collaboration. “After years of work, NANOGrav is opening an entirely new window on the gravitational-wave universe.”

Japanese Scientists Develop Novel, Completely Solid, Rechargeable Air Battery

Posted by in category: materials

Metals traditionally serve as the active materials for the negative electrodes in batteries. However, there’s been a shift towards using redox-active organic molecules like quinone-and amine-based compounds as negative electrodes in rechargeable metal–air batteries, which feature oxygen-reducing positive electrodes.

Here, protons and hydroxide ions participate in the redox reactions. Such batteries exhibit high performance, close to the maximum capacity that is theoretically possible. Furthermore, using redox-active organic molecules in rechargeable air batteries overcomes problems associated with metals, including the formation of structures called ‘dendrites,’ which impact battery performance, and have negative environmental impact.
