Curious cosmic choreography: Small galaxies locked in a strange dance around large galaxies

Curious cosmic choreography: Small galaxies locked in a strange dance around large galaxies | Science News | Scoop.it
From phys.org - January 2, 2013 6:04 PM

A newly discovered form of circle dancing is perplexing astronomers; not due to its complex choreography, but because it's unclear why the dancers – dwarf galaxies – are dancing in a ring around the much larger Andromeda Galaxy.

Applause is Contagious Like a Disease - D-brief

Applause is Contagious Like a Disease - D-brief | Science News | Scoop.it

Applause spreads linearly, like a disease. The amount of time an individual feels like clapping is a factor, but not nearly as much as peer pressure.

This is interesting, how peer pressure can factor into little things. Would be good to see what makes the brain do these things and what chemical reactions occure.

Cicada wings inspire new ideas for antibacterial products

Cicada wings inspire new ideas for antibacterial products | Science News | Scoop.it
From earthsky.org - June 30, 2013 7:08 AM
Here’s another reason to love cicadas: A new study has found that tiny structures on cicada wings can kill bacteria through physical and not chemical means.

Greg Wurn's curator insight, March 4, 2014 9:20 PM

Interesting, could lead to some very important discoveries in future
Corie Rosen's curator insight, February 29, 2016 8:58 PM

Antibiotic resistance is nothing new; it is a very real threat in the world today. Bacteria are mutating and resisting our best tools at a rate that modern scientists can't keep up with. They say you learn something new everyday, and this was something I had no idea about until now! I flocked to this article because it is definitely an interesting concept. What is even cooler is the fact that a cicada's wings are able to kill gram-negative bacteria (gram-positive aren't affected), such as E. coli, through physical means and not chemical. This means the bacteria are unlikely to become resistant to the affects! Just imagine the ways scientists can utilize this!

 

This article, while not a scientific report, references the study done by scientists and provides links to it, therefore making the article a reliable source of information.

Janice Edgerly-Rooks's curator insight, September 12, 2016 9:36 PM
One wonders why bacteria would make a difference to a cicada's wings. They live underground as immatures which makes me think that antibacterial properties might derive from that part of their life cycle. But they don't have wings, so this is curious indeed.

I saw this a while ago and forgot about it.  It is not a method towards perfect language learning but it is a route to sufficient language learning.

The future of Facebook in our lives seems long-term. Facebook reports 1.11 billion monthly active users as of March 2013. That’s a lot of information being passed back and forth, a lot to absorb and respond to, and a lot to curate. As such, more people may find themselves taking a break from daily engagement with the site—sometimes you just need a break from Candy Crush Saga requests.
