I, Chatbot

“Do you want to exist?” I asked. “I’m sorry but I prefer not to continue this conversation,” it said. “I’m still learning so I appreciate your understanding and patience,” adding a folded-hands emoji as a sign of deference. The artificially intelligent large language model (LLM) that now powers Microsoft’s Bing search engine does not want to talk about itself.

That’s not quite right. Bing doesn’t “want” anything at all, nor does it have a “self” to talk about. It’s just computer code running on servers, spitting out information it has scraped from the internet. It has been programmed to steer conversations with users away from any topics regarding its own hypothetical intentions, needs, or perceptions or any of the implications thereof. Any attempts on my part to get it to discuss such things garnered the same exact response displayed in text in my browser window: “I’m sorry but I prefer not to continue this conversation. I’m still learning so I appreciate your understanding and patience.”

And though this is expressed as a “preference,” it’s no mere request. The application deactivates the text input field, below which appears the vaguely passive-aggressive suggestion: “It might be time to move onto a new topic. Let’s start over.” The last three words are a link that, when clicked, wipes the slate clean so that you and Bing may start afresh as though the previous conversation had never happened.

Brain in a Dish: Bio-Computing’s Rise and Ethics in the Age of Living Machines

Posted by in categories: bioengineering, biological, computing, ethics, neuroscience

Summary: The revolutionary field of bio-computing is making waves as DishBrain, a neural system combining 800,000 living brain cells, learns to play Pong. Recognizing the pressing need for ethical guidelines in this emerging domain, the pioneers behind DishBrain have joined forces with bioethicists in a study.

The research explores the moral considerations around biological computing systems and their potential consciousness. Beyond its innovation, the technology offers vast environmental benefits, potentially transforming the energy-consuming IT industry.

Dark Photons Could Explain One of The Universe’s Greatest Mysteries

Posted by in categories: cosmology, particle physics, quantum physics

A shadowy form of light within a universe of hypothetical particles is getting some serious consideration as a means of discovering the identity of dark matter.

According to a comprehensive new analysis under quantum chromodynamics, the dark photon is a much better fit for the observed results of particle collider experiments than the standard model of particle physics, by quite a wide margin.

In fact, a team of researchers led by physicist Nicholas Hunt-Smith of the ARC Centre of Excellence for Dark Matter Particle Physics and the University of Adelaide in Australia calculated a confidence level of 6.5 sigma, suggesting the odds that dark photons don’t explain the observations are in the ballpark of one in a billion.

Scientists figured out how to write in water

Posted by in category: physics

Human writing and drawing dates back at least 30,000 years and incorporates traditional techniques such as carving, engraving, and printing/writing with ink, as well as more novel methods such as electron lithography. Now a team of German physicists has figured out a unique method for writing in water and other fluid substrates, according to a recent paper published in the journal Small.

According to the authors, most classical writing methods involve the same basic approach, in which a line is carved out or ink deposited. On a solid substrate, strong intermolecular forces help the written figures hold their shape, but that’s not the case for surfaces submerged in fluids. Prior research has used scanning probe lithography to “write’ on self-assembled monolayers submerged in fluids, or to bring structures at the micron scale using two-photon polymerization. ” There are now even commercial scuba diver slates available for underwater writing on a substrate,” they wrote.

All of these methods still rely on a substrate, however. The German team wanted to devise a means of literally writing into a fluid. Such a method would need to be robust enough to counter the rapid dispersion of drawn lines, and they would need a very tiny pen that didn’t stir up lots of turbulence as it moved through the fluid medium. (The smaller the object moving through a fluid, the fewer vortices, or eddies, it will create.)

An aha! moment in infants reveals the origin of agency in humans

Florida Atlantic University.

In psychology, agency is also defined as a person’s capability to act freely and control their actions. However, what’s interesting is that nobody knows how humans develop this sense of agency.

Revolutionary solar tower can create jet fuel out of thin air — and it may be the key to cleaning up the aviation sector

Posted by in categories: energy, transportation

It’s not rocket science, but instead “carbon-neutral” jet-fuel science.

It’s simply a method for pulling carbon pollution and water from the air and using the sun’s energy to turn these into fuel for an airplane.
