The debate over whether dinosaurs were cold-blooded like modern reptiles or warm-blooded like modern birds has been reignited by a new study analysing fossilised eggs

The new research from Yale has reignited controversy regarding whether dinosaurs were warm or cold blooded.

Solar powered plane which could be airborne for a year completes first flight Generating your own heat is an expensive lifestyle for animals and requires a lot more energy consumption. However, it provides benefits as it allows animals to function at a higher level when there aren't any external heat sources nearby, such as during the night or winter. Image: Theropod dinoasurs are the most direct ancestors of bird Dr Dawson is the lead author of the new study in the journal Science Advances which tested eggshell fossils from three major dinosaur groups. Using a technique called clumped isotope paleothermometry, the researchers figured out what the internal temperatures of dinosaurs were as the eggs inside them formed. Shells from species including the meat-eating theropod Troodon, the duck-billed Maiasaura, and the Megaloolithus, were all found to have been grown at temperatures significantly above that of the environment around them. "What we found indicates that the ability to metabolically raise their temperatures above the environment was an early, evolved trait for dinosaurs," Dr Dawson said.

"It's possible that dense feathers were primarily selected for insulation, as body size decreased in theropod dinosaurs on the evolutionary pathway to modern birds," Dr Dawson said. "Feathers could have then later been co-opted for sexual display or flying." Read more: Sky News

Weatherwatch: The downs and ups of plane contrailsChanging altitude when flying through humid air can cut warming by 59% Waiting for the first loony to try to correct the title to chemtrails... Imagine this: there are *still* people who will insist that these are chemitrails. Yep. 2020. Whatever trails these are it's not normal

Police left stroke victim in cell for 18 hours because they ‘thought he was drunk’‘I actually thought I was going to die at one point’ Police need more medical training & mental health training badly There must be ten thousand attorneys waiting outside the front door of the home of that poor individual Would it have mattered if he was drunk and had a stroke? looks like police need to have Dr's in employment

Criminals end up with 'smaller brains'Scans suggest people who show antisocial behaviour throughout life have some brain abnormalities. Not surprisingly Some criminals have small brains in the first place Big enough for them to know what they're doing.

Persistent lying, stealing and bullying linked to having a smaller brain, researchers findPeople who persistently lie, steal and bully have smaller brains, a major study suggests. You don`t say Sherlock! So the excuses that coming from broken homes etc has run its course...They now have smaller brains. Why don't you just give parents, schools, police etc back their authority. Oh!... and curtail certain human rights. Have you told Boris Johnson?

Bees may struggle in winds caused by global warming, study findsExperiment revealed increased wind speeds reduced the efficiency of their foraging The power of God Almighty is coming upon wind for signs and wonders Give over. What with winds, Boris and Brexit the poor blighters have no chance of survival. I'm still waiting for their first article on trans bees. Gotta love the words may, might, could etc. Never wrong.
