New technique promises to reveal a person’s history of viral infections
Science Focus
original post » Even before we became aware of emerging diseases like HIV and Ebola, there seemed to be plenty of viruses around. It felt like childhood was a blur of various illnesses—and these were the ones we hadn't been vaccinated for. So just how many types of viruses does a typical human get exposed to?
Ten, if a study in this week's issue of Science is to be believed. The study introduces a new way of getting a global history of all the viruses a person's immune system has had the pleasure of knowing. The technique has some significant limitations, but it still has the potential to provide new perspectives on how the human immune system functions.
First, the technique, which its creators are calling "VirScan." It relies on the fact that, after a person's immune system mounts an attack against a pathogen, a small collection of B cells, called memory B cells, continue to produce antibodies that recognize the invader. These allow the immune system to mobilize rapidly if the same pathogen is ever encountered again. But the memory B cells also allow us to study the antibodies they produce.

Orion Nebula and Trapezium Stars Star Sticker
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: envelope sealers, ornebcsfr, awesome astronomy images, orion nebula, emission nebula, trapezium stars, emission nebulae, hot young stars, star nursery, new born stars, dust clouds
Galaxies, Stars and Nebulae series A gorgeous picture from the deep universe featuring the bubbling, seething mass of gas and dust that is the Orion Nebula, 1500 light years away and the closest star-forming region to us. The nebula is a star nursery in which there are birthing, new-born, young and adult stars. Look carefully in the brightest central region and you'll see the Trapezium, four of the most massive stars in Orion.

1000 Sols
more »
Shortly before Mars' June 2015 conjunction, the Curiosity Rover celebrated 1000 sols on the red planet. After its August 5, 2012 landing, Curiosity's 1000th sol or martian day on the surface corresponded to planet Earth's calendar date May 31, 2015. Because the line-of-sight to Mars is close to the Sun near the conjunction, radio communications are affected and the six-wheeled, car-sized robotic rover cautiously remains parked at this spot for now. The view looks back toward the stomping grounds for Curiosity's nearly 10.6 kilometer trek so far, with the hazy rim of Gale Crater in the distance. The mosaicked panorama was constructed with images from navigation cameras taken on Curiosity's sol 997.

Merging Galaxies - The Antennae Galaxies Star Sticker
Here's a great sheet of stickers featuring a beautiful image from deep space
tagged with: envelope sealer, stretch frame, awesome astronomy images, super star clusters, agmcssc, antennae galaxies, merging galaxies, best hubble photos, ngc4038 ngc4039, new born stars, star cluster formation, dust clouds
Galaxies, Stars and Nebulae series A stunning outer space picture featuring two merging galaxies, known as the Antennae Galaxies - NGC4038 and NGC4039. As these galaxies hurtle through each other, billions of new stars are forced to precipitate out of the gas and dust clouds by the bunching and heating that's caused by the massive gravitic interactions. These tend to occur in clusters, the brightest and most condensed of them being known as super star clusters.
