A recent New Scientist article "The most ancient piece of you" (4 November 2017) discussed the common ancestors of living beings today.
But are plants included in this universal common ancestor?
The most common expressions by the dogs when faced with human attention were an inner eyebrow raise, which makes the dog’s eyes appear larger and more puppy-ish, and showing some tongue — coincidentally, most dog behavior literature suggests that the “tongue out” expression indicates relaxed attentiveness, though it can also indicate stress when accompanied by panting.
The team believes the findings suggest that dogs are sensitive to human attention and tailor their expressions accordingly in an active attempt to communicate, hinting at more flexible cognitive processes at work.
Because these distant galaxies are hard to see without serendipitous events like the lensing phenomenon that brought MACS 2129-1 to astronomers’ attention, those assumptions could be incorrect.
“Perhaps we have been blind to the fact that early ‘dead’ galaxies could in fact be disks, simply because we haven’t been able to resolve them,” said Toft.
“This new insight may force us to rethink the whole cosmological context of how galaxies burn out early on and evolve into local elliptical-shaped galaxies,” said lead researcher Sune Toft of the Dark Cosmology Center at the Niels Bohr Institute, University of Copenhagen, in a press release.This allows researchers to probe very early epochs of the universe that are otherwise unresolvable with today’s current instruments.
