The latest Jesus and Mo cartoon, called “sky,” came with the caption, “Important court case today.” It’s this, from the National Secular Society:

The prosecution of a man on trial tomorrow for burning a Quran could edge the UK “dangerously close to a prohibition on blasphemy”, the National Secular Society has warned.

Hamit Coskun will stand trial at Westminster Magistrates’ Court for protesting against Islamism outside the Turkish Consulate in February. He set fire to a Quran as part of the protest, which led to a man attacking him with a knife.

Coskun was subsequently charged with intent to cause “harassment, alarm or distress” against “the religious institution of Islam”.

And the cartoon reflects the case:

2024 was the first single year to surpass the 1.5°C global warming threshold – now scientists predict that a year above 2°C is possible in the near future

Raman spectroscopy uses scattered to identify a substance’s chemical ingredients and is one of the most widely used scientific methods in space exploration. It is used for lunar exploration to identify volcanic minerals, water ice, and space weathering, and has been limited to obtaining data from lunar orbiters. But how can Raman spectroscopy be conducted on the lunar surface to help us better understand our nearest celestial neighbor? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of NASA and academic researchers discussed the Raman Cube Rover (R3R), which would be delivered to the lunar surface via the private space company, Astrobotic.

People always want to know what will happen to Earth when the Sun eventually swells up as a red giant. For one thing, the expanding Sun will turn the inner planets into cinders. It will almost certainly spell the end of life on our planet. Mars might become more temperate and hospitable to life. In addition, it could well be a boon for the gas giant Jupiter and its moons. That's because the habitable zone of the Solar System will move outward from where it is now, to a spot encompassing the Jovian system and forcing changes on all of those worlds.

SpaceX’s Starship super-rocket got off to a great start for its ninth flight test, but the second stage ran into a host of issues and made an uncontrolled re-entry.

Researchers have designed a liquid hydrogen storage and delivery system that could help make zero-emission aviation a reality. Their work outlines a scalable, integrated system that addresses several engineering challenges at once by enabling hydrogen to be used as a clean fuel and also as a built-in cooling medium for critical power systems aboard electric-powered aircraft.

Researchers find that iron powder, an inexpensive alternative to activated carbon, does a better job at filtering PFOS from water -- it's 26 times more effective.

Weather forecasts based on AI are faster and sometimes more accurate than traditional ones, but they may miss rare and unprecedented weather events – which are becoming more common as the climate changes

The galaxy cluster Abell S1063 dominates the center of this JWST image. It's a massive cluster of galaxies about 4.5 billion light-years away. While it dominates the picture, it's not the primary target. It serves as a gravitational lens that magnifies even more distant galaxies that appear as glowing streaks of light around its circular edges.

Nuclear Thermal Propulsion (NTP) has stood as a promising potential alternative propulsion technology for decades. Chemical rockets have begun to reach their theoretical maximum efficiency, and their developers have switched their focus to making them cheaper rather than more efficient. NTP should answer that by offering high thrust and specific impulse. NASA's DRACO Program, the standard-bearer for NTP systems, provides a specific impulse of around 900 seconds, about double a traditional chemical rocket, but half that of most ion thrusters. To increase that number even further, researchers at the University of Alabama at Huntsville and The Ohio State University have been working on a novel configuration of NTP called the Centrifugal Nuclear Thermal Rocket (CNTR) that promises almost to double the specific impulse of traditional NTP systems while maintaining similar thrust levels. However, the system has some engineering challenges to overcome, and a new paper coming out in Acta Astronautica describes some incremental progress on making this improved engine a reality.

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:

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.
