<\/p>\n Solar magnetic fields are powerful things, occasionally kinking, twisting and breaking to launch enormous flares alongside torrents of charged particles that can cause powerful geomagnetic storms on Earth. Another new study this week revealed just how catastrophic the most extreme of these superstorms can be, with the inevitable next one having the potential to wipe out all of our satellites<\/a>.<\/p>\n Meanwhile, Comet 3I\/ATLAS has arrived at perihelion, or its closest point to our star, releasing gas in overdrive and rapidly brightening<\/a>, NASA<\/a> spacecraft have revealed. And a closer look by the James Webb Space Telescope<\/a> found that the comet’s billions of years in interstellar space have exposed it to space radiation that has transformed its chemistry<\/a>. We also covered photos of the comet taken before it reached perihelion<\/a>, and we can expect many more, as two spacecraft stand poised to pass right through the comet’s tail<\/a>.<\/p>\n Nanotyrannus was real and not just a teenage T. rex<\/p>\n \n An analysis of two “Dueling Dinosaurs” has revealed that Nanotyrannus is its own species after all. (Image credit: Anthony Hutchings)<\/p>\n A remarkable fossil find has thrown lit dino-mite into a controversy about whether a mini-tyrannosaur was a young Tyrannosaurus rex or its own unique species. The debate has roared on for nearly four decades, but a fossil known as the “Dueling Dinosaurs” may have finally offered a conclusive answer. Unearthed in 2006, the fossils show a Triceratops who appears to be locked in battle with a fierce tyrannosaur.<\/p>\n Now, a jaw-dropping analysis<\/a> of the “Dueling Dinosaurs” has revealed that the tyrannosaur likely wasn’t a juvenile T. rex, as many experts had assumed, but a fully grown adult of a previously debated species called Nanotyrannus lancensis.<\/p>\n Following the find, paleontologists now largely accept that Nanotyrannus is its own species. But to confuse matters further, a separate team has also named a different new species in the genus \u2014 Nanotyrannus lethaeus. So does this mean the dust has finally settled?

You might be the best at getting it to work for you, according to a new study that found chatbots give more accurate answers when you’re being mean to them<\/a>. The difference in accuracy is fairly small, however, with a 4% improvement between prompts classed as very polite to those that are very rude.<\/p>\n The researchers nonetheless caution against this approach, as there’s a chance that being truculent and ill-mannered to the bots could spill over to your behavior with fellow humans.

The U.S. Government is turning its back on it. (Image credit: Adri\u00e1n Astorgano)<\/p>\n The introduction of mRNA-based vaccines for COVID-19 was a key achievement during the previous Trump administration, swiftly curtailing the pandemic<\/a> in the mere months the vaccines took to go from conceptualization to mass production.<\/p>\n Yet now the second Trump government appears bent upon undoing its previous work through funding freezes, mass layoffs and the scrapping of research projects into mRNA research.<\/p>\n As the U.S. government continues to divest from the technology, scientists are worried that the revolutionary treatments it offers for cancer, immune deficiencies and genetic disorders could be left behind.

(Image credit: ESA\/Webb, NASA & CSA, J. H. Kastner (Rochester Institute of Technology))<\/p>\n The James Webb Space Telescope served us a spooktacular treat for Halloween this week, capturing never-before-seen details of the Red Spider Nebula<\/a>, its filaments twisting and stretching like the limbs of a gigantic arachnid.<\/p>\n Planetary nebulas such as this one form when stars like our sun reach the end of their lifetimes, expanding into red giants and shedding their outer layers to form shrouds of superheated dust. The cosmic spider’s legs shimmer with molecular hydrogen, and the fragmenting gas outflows from the dying star give the cosmic limbs a distinctly hairy appearance.<\/p>\n <\/p>\n Want more science news?
