WASH YOUR DAMN HANDS!...And Clean Your Stuff [Mike the Mad Biologist]

No, not that stuff (well, actually, yes, that stuff too, but I definitely don't want to know about it). One of the important tools in fighting infectious disease is disinfecting surfaces. Which brings me to a recent paper about cruise ships and cleanliness. In June 2006, 43 norovirus outbreaks occurred on thirteen vessels. Noroviruses can cause severe vomitting and diarrhea, and in children, particularly infants, can be deadly (also see Aetiology). In the paper, the authors decided to examine how often bathroom surfaces on cruise ships are cleaned:

Over 1.1 Million Sugar Activities in the Wild!

Congratulations to Sugar Labs! The ever demure Walter Bender let is slip this week that his team has passed a very important psychological milestone:

1. I had been meaning to mention that already several weeks ago we exceeded one-million downloads from activities.sugarlabs.org. We are now over 1.1 million.

Now you can't assume one Activity per child, but this statistic shows that the 1 million XO laptops in the hands of children worldwide are being updated with the latest code - those 1.1 million downloads can't be from G1G1 donors alone. But it does make me ask a few questions:

NGC 2623: Galaxy Merger from Hubble Credit: ESA and
A. EvansStony Brooket al.

Where do stars form when galaxies collide?

To help find out, astronomers imaged the nearby galaxy merger
NGC 2623 in high resolution with the
Hubble Space Telescope in 2007.

Analysis of this Hubble image and images of
NGC 2623 in
infrared light by the
Spitzer Space Telescope, in
X-ray light by
XMM-Newton, and in
ultraviolet light by
GALEX,
indicate that two originally
spiral galaxies appear now to be
greatly convolved and that their cores have unified into one
active galactic nucleus (AGN).

Star formation continues around this core near the
above image center, along the stretched out
tidal tails visible on either side,
and perhaps surprisingly, in an off-nuclear region on the upper left where
clusters of bright blue stars appear.

Galaxy collisions can take hundreds of millions of years and take several gravitationally destructive passes.

NGC 2623, also known as Arp 243, spans about 50,000 light years and lies about 250 million light years away toward the constellation of
the Crab (Cancer).

Reconstructing the original galaxies and how
galaxy mergers happen is often challenging,
sometimes impossible, but generally important to understanding
how our universe evolved
