Matthew sent me this qui, involving ten pairs of photos in Brittanica Education. The object is to see whether you can tell which is generated by AI and which is real.  Click on the headline below to go to the quiz, which is fun to take. After you click on which photo you think is real, the explanation of why you should have known pops up.

Here is one pair of photos, but take the quiz yourself, which is quick.  Matthew says “I got 10/10”, but poor PCC(E) got only 9/10. Some are more obvious than others.

Have a look and then go to the quiz. Give us your score and then beef if you wish. This is the last one:

The worlds inside our heads can be dramatically different. What does that reveal about how our minds shape our lives, asks cognitive neurologist Adam Zeman

A skeleton found in London records a brutal killing about 1200 years ago, thought to be a rare example of a judicial execution of a woman in medieval England

Most people have witnessed -- or rather smelled -- when a protein enzyme called sulfite reductase works its magic. This enzyme catalyzes the chemical reduction of sulfite to hydrogen sulfide. Hydrogen sulfide is the rotten egg smell that can occur when organic matter decays and is frequently associated with sewage treatment facilities and landfills. But scientists have not been able to capture a visual image of the enzyme's structure until now, thus limiting their full understanding of how it works.

A team analyzed a range of YouTube videos that focused on learning music by ear and identified four simple ways music learning technology can better aid prospective musicians -- helping people improve recall while listening, limiting playback to small chunks, identifying musical subsequences to memorize, and replaying notes indefinitely.

A research team has discovered ferroelectric phenomena occurring at a subatomic scale in the natural mineral Brownmillerite.

A new study has found that a smartphone app that tracks household water use and alerts users to leaks or excessive consumption offers a promising tool for helping California water agencies meet state-mandated conservation goals. The study found that use of the app -- called Dropcountr -- reduced average household water use by 6%, with even greater savings among the highest water users.

Laser-based metal processing enables the automated and precise production of complex components, whether for the automotive industry or for medicine. However, conventional methods require time- and resource-consuming preparations. Researchers are now using machine learning to make laser processes more precise, more cost-effective and more efficient.

New technology that uses light's color and spin to display multiple images.

Miniature organs on a chip could allow us to do scientific studies with great precision, without having to resort to animal testing. The main problem, however, is that artificial tissue needs blood vessels, and they are very hard to create. Now, new technology has been developed to create reproducible blood vessels using high-precision laser pulses. Tissue has been created that acts like natural tissue.

Scientists have produced the finest images of the Sun's corona to date. To make these high-resolution images and movies, the team developed a new 'coronal adaptive optics' system that removes blur from images caused by the Earth's atmosphere. Their ground-breaking results pave the way for deeper insight into coronal heating, solar eruptions, and space weather, and open an opportunity for new discoveries in the Sun's atmosphere.

Persons with Parkinson's disease increasingly lose their mobility over time and are eventually unable to walk. Hope for these patients rests on deep brain stimulation, also known as a brain pacemaker. In a current study, researchers investigated whether and how stimulation of a certain region of the brain can have a positive impact on ambulatory ability and provide patients with higher quality of life. To do this, the researchers used a technique in which the nerve cells are activated and deactivated via light.

When it comes to public attitudes toward using self-driving cars, understanding how the vehicles work is important -- but so are less obvious characteristics like feelings of excitement or pleasure and a belief in technology's social benefits.

Engineers developed a fuel cell that offers more than three times as much energy per pound compared to lithium-ion batteries. Powered by a reaction between sodium metal and air, the device could be lightweight enough to enable the electrification of airplanes, trucks, or ships.

More than 60 ancient tools found in France and Spain have been identified as whale bone, and the evidence shows that people made tools from this material a thousand years earlier than previously thought

Your imagination isn't just one thing. The latest neuroscience is untangling just how diverse this faculty really is, says cognitive neurologist Adam Zeman

Modern ground-based telescopes rely on adaptive optics (AO) to deliver clear images. By correcting for atmospheric distortion, they give us exceptional pictures of planets, stars, and other celestial objects. Now, a team at the National Solar Observatory is using AO to examine the Sun's corona in unprecedented detail.

The chance of a planet forming in the outer reaches of the solar system - a hypothetical Planet Nine - could be as high as 40 per cent, but it would have been a rough start
