In the 1960s, we thought the best way of sending stuff between Earth and space was through a transporter. These days, turns out all it takes is an e-mail and a special 3-D printer. The first tool created in space, a rachet, was made last week on the International Space Station using plans beamed from Earth. Now, we get to see if it actually works.

Remember how breathless we felt when the Philae lander actually made it to the surface of its target comet a few weeks ago? Sure, the maneuvers didn’t go as planned, but the images the spacecraft obtained in its brief spurts of activity on the surface are still being shared and discussed eagerly by scientists (amid a controversial image release policy, to be sure.)
Well, the truck delivery for Philae — the Rosetta spacecraft, still doing maneuvers above — is going to do something special in February. The machine is going to scoot down real close to the comet, just before heating from the Sun could make it dangerous to do so due to gas and dust emissions.

Archaeologists from The Hebrew University of Jerusalem’s Institute of Archaeology have discovered a monumental entryway to the Herodian Hilltop Palace at the Herodium National Park. The unique complex was uncovered during excavations by The Herodium Expedition in Memory of Ehud Netzer over the past year, as part of a project to develop the site for tourism. —> Read More Here

Personalized advertisements on the Internet not only attract more attention, they also remain in our memory longer than impersonal ads. This is the result of a study conducted by Professor Kai Kaspar from the Psychology Department of the University of Cologne in collaboration with his colleagues Moritz Köster, Marco Rüth and Dr. Kai-Christoph Hamborg in Osnabrück. Specifically, they investigated the gaze behavior of female students on websites. —> Read More Here

Does exposure to cold weather really make you more likely to catch a cold?
No, it doesn’t. In fact, as a new YouTube video entitled Cold Weather Myths explains, research suggests just the opposite: frigid temps lower the risk of catching cold by stimulating the body’s production of infection-fighting immune cells known as granulocytes.
And you know how they say being wet in the cold, or failing to bundle up, can make you sick? According to the video, part of the “Healthcare Triage” series, those too are just myths.
The persistence of folk wisdom linking the common cold virus and winter is nothing to sneeze at. According to one survey cited in the 2012 book “Because I Said So!,” 38 percent of Americans believe being out in cold weather can make you sick.
Needless to say, the debate over how we catch colds probably isn’t going to end soon. But whether or not you put on your overcoat, one of the few indisputable facts about the common cold is that many of us will catch one. According to Harvard Medical School, Americans endure a billion colds annually.
Achoo to that! —> Read More Here
