Cutting off hair in ancient Asia (Japan, china, Korea & possibly some other Asian cultures) symbolizes being banished or rejected from their home. In the more modern age that is now, cutting long hair into a short cut means to forget the past, leaving the old and starting anew.

To scientists' delight, the incredible appendage from 99 million years ago is covered in feathers.
The tail of a 99-million-year-old dinosaur, including bones, soft tissue, and even feathers, has been found preserved in amber, according to a report published today in the journal Current Biology.

While individual dinosaur-era feathers have been found in amber, and evidence for feathered dinosaurs is captured in fossil impressions, this is the first time that scientists are able to clearly associate well-preserved feathers with a dinosaur, and in turn gain a better understanding of the evolution and structure of dinosaur feathers.
We clearly need a new Jurassic Park movie featuring cute feathery dinosaurs.

Okay this is really really cool BUT IT IS CRIMINAL to leave out the funniest part of this story.
The paleontologist who “discovered” this sample didn’t dig it up, he and his team found it in an amber market where the amber it was preserved in had been shaped and was being sold as jewelry.
This is both ridiculous and exciting though, because on one hand it’s a shame this sample was cut and shaped before anyone who knew what it was could get their hands on it, it also gives us an idea of how many other samples might be in that particular amber mine.
Also this amazing quote from Xing:
“I was not sure that (the trader) really understood how important this specimen was, but he did not raise the price.”
NGC 6357: Cathedral to Massive Stars : How massive can a normal star be? Estimates made from distance, brightness and standard solar models had given one star in the open cluster Pismis 24 over 200 times the mass of our Sun, making it one of the most massive stars known. This star is the brightest object located just above the gas front in the featured image. Close inspection of images taken with the Hubble Space Telescope, however, have shown that Pismis 24-1 derives its brilliant luminosity not from a single star but from three at least. Component stars would still remain near 100 solar masses, making them among the more massive stars currently on record. Toward the bottom of the image, stars are still forming in the associated emission nebula NGC 6357. Appearing perhaps like a Gothic cathedral, energetic stars near the center appear to be breaking out and illuminating a spectacular cocoon. via NASA
