Saturday Quote: A confused discovery from Webb. Early human faces. Humans and dogs like to cool them down together

This week we reported a difficult experience of humans trying to read dog emotions. Researchers reported that male blue-lined octopus paralyze women before mating with females to avoid feeding. Physicists have demonstrated quantum advantages in simple cooperative games. Furthermore, galaxies clearly prefer to rotate clockwise. Researchers discovered the oldest facial bones of early humans. And play interventions reduce stress markers in both humans and dogs.

Galaxy bias

Essentially, every image generated by James Webb Space Telescope contains enough data to study your entire career. New research analyzing the 263 galaxies in the Jades field acquired by Webb has discovered completely unexpected discoveries with deep meaning in the origins of the universe and the methods used by astronomers to measure cosmic distance. Discovery is easy. The vast majority of the universe’s galaxies, two-thirds, rotate clockwise. The other three rotate counterclockwise (or “Australian Awees”).

“The analysis of galaxies was done by quantitative analysis of their shapes, but the differences are very obvious and anyone looking at the image can see it.” The problem is that it is expected that a completely random universe will produce an almost even number of galaxies with either spin direction.

The researchers suggest two explanations. One is that the universe was born by rotating according to a theory like black hole cosmology, which suggests that the entire universe is inside a black hole. The second possible explanation for this overrepresentation of clockwise galaxies is the Doppler shift effect.

Galaxies rotating in the same direction appear red compared to the Milky Way spin. The opposite spinning galaxy looks blue. Because the sun rotates around the center of the Milky Way, light coming from a galaxy rotating in the opposite direction of the sun’s trajectory appears bright.

“If that’s the case, then deep space distance measurements need to be readjusted,” Shamir said.

Old face

A group of archaeologists who excavated in northern Spain in 2022 revealed the oldest known facial bones of human ancestors. The fossils, which are part of the bone and upper jaw on the left cheek, date to 1.1 million to 1.4 million years old. The “The Oldest Man” record holder is a collection of H. erectus fossils found in Georgia, on the border between Georgia and Asia, estimated to be 1.8 million years old, but the body did not contain a face.

The new discovery clearly shows that early humans ventured into Europe over a million years ago. Researchers report in their studies that midfaces have H. erectus properties that contain a primitive nose that is not projected as much as H. sapiens. It has a narrower midface than previous H. erectus discoveries. Researchers call it H. affinis erectus, as tooth deficiencies make it difficult to clearly identify species. In the same geological layer, researchers also discovered animal bones covered in stone tools.

Uneducated dogs benefit college students

According to researchers at Chiang Mai University in Thailand, playing with a dog for just 15 minutes reduces stress for humans and dogs themselves. Specifically, the group of stressed students who participated in this study had reduced heart rate and levels of stress hormone cortisol after dog mental health intervention. Compared to just before dog interactions, students’ self-reported stress levels decreased by 33.5%.

Furthermore, dogs in this study had lower fecal cortisol levels one week after the intervention. None of the dogs in this study are certified as treatment dogs, and researchers suggest that humans can help reduce stress levels, even in situations where higher-educated dogs are not available.

“Overall, these findings contribute to understanding the beneficial effects of human dog interactions on human stress levels, highlighting the importance of dealing with stress in both human and animal during targeted interventions,” the researchers wrote.
