Scientists Discover New Type of Extra-Chromosomal DNA

eccDNA
Profile of eccDNA throughout the life cycle of Drosophila. 2D-gel blots of DNA samples from different stages of the Drosophila life cycle were hybridized with a total genomic DNA probe (A—F) or a 5S rDNA probe (G—J). The panels represent 2D-gel blots of (A,I) pre-MBT embryos, (B,H) late embryos, (C,I) first-instar larvae, (D,J) third-instar larvae, (E) young adult flies (1 day old), and (F) old adult flies (33 days old). The hybridization patterns reveal a decrease in the relative amount of eccDNA during embryogenesis (cf. panels A,B and panels G,H), and a gradual return to the initial levels in the larva and young adult stages. A slight decrease is observed in eccDNA levels in old adult flies compared with young adult flies. Image: genome.cshlp.org

Scientists from the University of Virginia and University of North Carolina have discovered a previously unidentified type of circular DNA molecule occurring outside the chromosomes in mouse and human cells. The findings were published in the journal Science.

Listening to Mozart Can Make You Smarter but No More than Justin Bieber

It’s believed that listening to Mozart and other classical music recordings will make the listener smarter, but this is a misconception as there’s nothing unique about Mozart’s ability to increase your mental abilities. Ultimately, there are probably a wide variety of different kinds of music that make people more receptive to cognition, but this is down to the individual taste of each person.

Stargate Universe Human S01E14 (Syfy)

I’ve never been a Stargate fan. I’ve tried watching SG-1 and Stargate Atlantis, but never really found them compelling enough. I actually like the original movie with Kurt Russell, but the series never really interested me that much. One of my friends recently bought all of the seasons cheaply. I thought about watching them, but ran out of time. Scalzi is a creative consultant on this series and it looks pretty interesting, so I’ve decided to give it a go.

Now, before any bitching and hating starts― too late, it’s already started, I haven’t bothered to read, review, or watch any of the Stargate series, and I’m not going to. I’ve watched a couple of episodes and didn’t continue. I tried Stargate Atlantis, but didn’t like it. My friend told me that starting season 4, SG-1 was really good. I can’t really comment on that as I stopped watching the series after a few episodes.

Basically, I’m a new viewer of Stargate, but I’m not a science-fiction novice. It puts me in an interesting spot about reviewing this show. My point of view is from someone who hasn’t watched any of the SG shows, so this review and recap should be interesting to those of you who haven’t watched SG before. For the others, leave some comments and start a discussion.

Is the show good or bad? Read on to find out more.
