Cancer vaccine success | Harvard Gazette Online
A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals, scientists report this week (Nov. 25) in the journal Science Translational Medicine. The new approach, pioneered by bioengineers and immunologists at Harvard University, uses plastic disks impregnated with tumor-specific antigens and implanted under the skin to reprogram the mammalian immune system to attack tumors. The journal article describes the use of such implants to eradicate melanoma tumors in mice. “This work shows the power of applying engineering approaches to immunology,” said David J. Most cancer cells easily skirt the immune system, which operates by recognizing and attacking invaders from outside the body. Conventional cancer vaccinations remove immune cells from the body, reprogram them to attack malignant tissues, and return them to the body. Mooney’s co-authors are Omar A.
National Geographic Photo Contest 2011 - In Focus
National Geographic is currently holding its annual photo contest, with the deadline for submissions coming up on November 30. For the past nine weeks, the society has been gathering and presenting galleries of submissions, encouraging readers to vote for them as well. National Geographic was kind enough to let me choose among its entries from 2011 for display here on In Focus. Gathered below are 45 images from the three categories of People, Places, and Nature, with captions written by the individual photographers. [45 photos] Use j/k keys or ←/→ to navigate Choose: Many people pilgrimage to Uluru, but what is seen there often depends on where you've come from. Eruption of the Cordon del Caulle.

New Solution For Tooth Decay: Just Grow A New Tooth
Cavity seen on an x-ray.: image via webMD.com The main treatment for cavities - drill and fill - has given the dental profession a bad rep. Ask people what they hate to do most, and I bet half of them will say "Going to the dentist." But now, French researchers at the National Institute for Health and Medical Research in Paris have developed a painless and simple method that could very soon put an end to fillings. You know - Novocaine, water, air, drilling, sore mouth, and chemical taste? Fillings are used to fill holes left by tooth decay. They made a gel substance from MSH (melanocyte-stimulating hormone) with poly-L-glutamic acid, a strong survivor often used to transport drugs through our bodies because it can fight off stomach acids that might destroy the medication. MSH is a substance that is naturally produced by the pituitary gland and it is active in determining the lightness or darkness of our skin color. Isn't science great?

12 Must-See Skywatching Events in 2012 | 2012 Skywatching Events Guide & 2012 Venus Transit | Amateur Astronomy
This story was updated on Jan. 2. As the year 2011 comes to a close, some might wonder what is looming sky-wise for 2012? What celestial events might we look forward to seeing? I've selected what I consider to be the top 12 "skylights" for this coming year, and list them here in chronological order. Not all these events will be visible from any one locality … for the eclipses, for instance, you'll probably have to do some traveling … but many can be observed from the comfort of your backyard. Hopefully your local weather will cooperate on most, if not all, of these dates. Jan. 4: Quadrantid meteor shower peaks This meteor shower reaches its peak in the predawn hours of Jan. 4 for eastern North America. From the eastern half of North America, a single observer might count on seeing as many as 50-to-100 "Quads" in a single hour. The first major meteor shower of 2012 takes place on the night of Tuesday, Jan. 3 and the morning of Wednesday, Jan. 4. March 3: Mars arrives at opposition
Left 4 Dead - Fan made film by Airsoft GI - Geeky.ly
Like Left 4 Dead this is a little bit mental. There are surprises aplenty in here (you’ll know exactly what I mean) but you’ll either take it as it was intended (as a bit of fun) or there’ll be immense nerd rage. Either are completely acceptable. I’ll let you watch it before I ramble on about the rest. The inclusion of cameo characters is a bold move but let’s think about it this way; I’ve seen more wooden acting in multi-million dollar blockbusters. They’ve captured the mood of Left 4 Dead perfectly along with the frenetic pace of action. Have you made a short film you’d like featured on Geeky.ly? gamingShort film Related Posts About the Author: Trey Douglas Builder of worlds, raider of dungeons, explorer par excellence and almighty ruler of Nerfed.co.uk. « Siri: The Holiday Horror Movie – A short by Rooster Teeth TFTS Presents: The Top 5 Xbox Live Arcade Titles of 2011 »
