17 December 2010 - HIV

I can't do a full blog post today (which counts as Thursday's...sorry if my posts are late, being nocturnal messes with your days a bit), but I can do a partial one.  I'm packing up and getting ready to go out of state on Saturday, so I've missed a lot on Twitter and don't have a bunch of time to blog.

I'll be heading out Saturday, and I'm not yet sure if I'll be blogging there or not.  It kind of just depends on how much time I have and how frustrated I get trying to type out an entire post with links in my cell phone (no internet where I'm headed).  Perhaps just blurbs when something particularly interesting finds its way to my screen.  I WILL still tweet articles, though, and I'll be back in town on the 28th or 29th.



The biggest thing I've seen since last post was a story about a man who is tentatively being announced as cured of HIV.  He underwent a bone marrow transplant four years ago from someone with a genetic immunity (resistance?) to the virus.  Since then, his tissues have been tested for the virus and he's been clear so far.  The two big concerns about his case are first, that it's tough to really be sure he's done with HIV.  The virus can hide out undetected, occurring years down the road.  The second concern is that this treatment is not practical to be performed on anyone else.  Bone marrow transplants are dangerous and not approved for HIV, but if it proved anything, it proved that the gene can make a difference in an already-infected individual.  The case points to gene therapy in future research.

Here's the article at Reuters.



Heh, the comments are kind of amazing:

"If we stop paying “research scientists?” we may just find the correct cure. If you cannot do the job, get another source of income. that goes for all research institutes."

Nice!

Oh, of course!  *doh!*  If we don't PAY them, an answer will just fall into our laps!  Geniuses with expensive degrees work for free!  XD  I don't see you working OT in a lab, buddy.

Okay okay, enough with the sarcasm.  HIV has become sort of the ultimate task over the years, so it's nice to see a mark of progress amongst the reports of leads.  Suspicious comments or no.  Have a great one, and I'll see you guys sooner/later!

Later gators,

15 December 2010 - O What a Slacker I Be (Gene Machines and Zombie-Food)

Or maybe there just hasn't been much Science in the news lately.  I'm hoping to make the switch in the near(ish) future from relying wholly on news sources for my info to actually reading *gasp* the papers.  Wouldn't that be sweet?  One of these days I'm going to have to get back to big-people college.  I miss micro.  Hell, I kind of even miss genetics.  Having a huge library of mouse papers to peruse for the cost of tuition was pretty damned enviable, for that matter.

Okay, I really should not hate on my current college (which I adore).  I'm being tested on a surprising pleasant amount of micro and pathology in my vet tech degree.  ;)

Sorry if I'm missing big stories - feel free to point them out if you don't spot them on the twitter feed or here.  I work nights now, and unfortunately, most of the big stuff gets posted during the daylight hours when I'm fast asleep!  I do my best, though.  :)  Follow me on Twitter if you don't want to mess with the tweetish widget.

Onward!



First today isn't really Science, but...for Science.  A company (surely they aren't the only one with the goal!) is pushing gene sequencers down the same path as computers took way back when - making them smaller, faster, and more affordable.  They don't seem to pack a lot of oomph yet, but for those of us interested in genomes that are not as big as our own, they seem pretty darn flashy.  They seem aimed more at...well...me, than people with their own labs, but perhaps they can take a little outta the grant budget and let more dinero go to other equipment?  Check out the link at the end of the post for more info.

Oh, and a study out of the University of South Florida took a peek at how umbilical cord blood cells (the same cells mentioned over and over again in stem cell debates) affect the hippocampal neurons of the aging brain - rat, in this case.  Normally, this is the first area of the brain to show the effects of aging, especially in cases with Alzheimer's or other cognitive age-related disorders.  However, when HUBCs were given, the neurons appeared to be both protected and stimulated to actually grow.  Just how they helped is still speculation, but for now it's exciting to note that HUBCs may be part of the answer to disorders like Alzheimer's, Parkinson's, and others!

That's all you get today.  Told you there hasn't been a whole lot to write about!  At least I'm writing, right?  Right?



See ya!

Testing, Testing, Uno Dos Tres!

First, I must point out if I haven't already, that the twitter feed has gone from updating once every now and then to multiple times a day. It's great stuff, even if I don't write about all of it, and I highly recommend checkin it out.

Also, I just realized the twitter widget insists on opening all links in the widget instead of in a new page. Sorry 'bout that. I'll fix it when I figure out how.

ALSO, I'm writing this on my phone to try it out...but the lack of formatting is driving me le-bonkers. Meh. Hence the testing.

So! If you haven't already, I really recommend reading both the paper and critique of the arsenic bacteria so frequently discussed lately. The blogged response and link is here: http://bit.ly/he8ECs

Sorry about this not really being an awesome post. I'm pretty zonked. There really is a ton of snazzy Science on the feed, check it. Be back soon!
