Posting a Diary Entry

Daily Kos welcomes blog articles from readers, known as diaries. The Intro section to a diary should be about three paragraphs long, and is required. The body section is optional, as is the poll, which can have 1 to 15 choices. Descriptive tags are also required to help others find your diary by subject; please don't use "cute" tags.

When you're ready, scroll down below the tags and click Save & Preview. You can edit your diary after it's published by clicking Edit Diary. Polls cannot be edited once they are published.

If this is your first time creating a Diary since the Ajax upgrade, before you enter any text below, please press Ctrl-F5 and then hold down the Shift Key and press your browser's Reload button to refresh its cache with the new script files.

ATTENTION: READ THE RULES.

  1. One diary daily maximum.
  2. Substantive diaries only. If you don't have at least three solid, original paragraphs, you should probably post a comment in an Open Thread.
  3. No repetitive diaries. Take a moment to ensure your topic hasn't been blogged (you can search for Stories and Diaries that already cover this topic), though fresh original analysis is always welcome.
  4. Use the "Body" textbox if your diary entry is longer than three paragraphs.
  5. Any images in your posts must be hosted by an approved image hosting service (one of: imageshack.us, photobucket.com, flickr.com, smugmug.com, allyoucanupload.com, picturetrail.com, mac.com, webshots.com, editgrid.com).
  6. Copying and pasting entire copyrighted works is prohibited. If you do quote something, keep it brief, always provide a link to the original source, and use the <blockquote> tags to clearly identify the quoted material. Violating this rule is grounds for immediate banning.
  7. Be civil. Do not "call out" other users by name in diary titles. Do not use profanity in diary titles. Don't write diaries whose main purpose is to deliberately inflame.

Please begin with an informative title:

Monday is here once more.  The time for science talk has arrived.  Time to brighten your day with selections from science sites across the globe.  New discoveries, new takes on old knowledge, and other bits of news are all available for the perusing in today's information world.  Today's tidbits include Himalayan glaciers will shrink even if temperatures hold steady, wax-filled nanoyarn behaves like superstrong muscle, how groundwater pumping affects stream flow, and saving pink salmon from sea lice.

Pull up that comfy chair and grab a spot on the porch.  There is always plenty of room for everyone.  Another session of Dr. Possum's science education, entertainment, and potluck discussion is set to begin.

Intro

You must enter an Intro for your Diary Entry between 300 and 1150 characters long (that's approximately 50-175 words without any html or formatting markup).

Featured Stories
Researchers tell us the Himalayan glaciers will continue to shrink for years to come even if temperatures remain steady.

...even if climate remained steady, almost 10 percent of Bhutan's glaciers would vanish within the next few decades. What's more, the amount of melt water coming off these glaciers could drop by 30 percent.

(Researcher) Rupper says increasing temperatures are just one culprit behind glacier retreat. A number of climate factors such as wind, humidity, precipitation and evaporation can affect how glaciers behave. With some Bhutanese glaciers as long as 13 miles, an imbalance in any of these areas can take them decades to completely respond.

New artificial muscles made from wax-filled nanoyarn are superstrong, able to life 100,000 times their weight.
The artificial muscles are yarns constructed from carbon nanotubes, which are seamless, hollow cylinders made from the same type of graphite layers found in the core of ordinary pencils. Individual nanotubes can be 10,000 times smaller than the diameter of a human hair, yet pound-for-pound, can be 100 times stronger than steel.
With so many people around the world dependent on surface water for sustenance the relationship between groundwater and streamflow is an important one.
Groundwater and surface-water systems are connected, and groundwater discharge is often a substantial component of the total flow of a stream. In many areas of the country, pumping wells capture groundwater that would otherwise discharge to connected streams, rivers, and other surface-water bodies. Groundwater pumping can also draw streamflow into connected aquifers where pumping rates are relatively large or where the locations of pumping are relatively close to a stream.
Both the captive and wild populations of pink salmon in British Columbia are threatened by sea lice infestation.
The researchers found that the fall and winter anti-parasite treatments greatly reduced louse numbers on the penned Atlantic salmon by the time wild juvenile pink salmon passed close to the farming sites on their annual migration from B.C. rivers out to the ocean.

Although changes to the parasite treatment schedule in the Broughton Archipelago show positive results.

Now concerns about the use of pesticides in the ocean must be addressed.
