"Kann ein Mensch tatsächlich auf der Wasseroberfläche eines Sees gehen? Die Wissenschaft hat eine plausible Erklärung, wie Jesus dieses Kunststück auf dem See Genezareth gelang. Sicher ist, dass es sich beim biblischen See um den heutigen See Kinneret handelt. Die Ozeanografen der Florida State University fanden heraus, dass hier in der Vergangenheit ein besonderes Wetterphänomen auftrat: Alle 160 Jahre kam es zu Blitzeis, das ein Betreten des Sees möglich machte. Begünstigt wurde die Eisbildung durch eine Atmosphärentemperatur, die zu Jesu Zeiten um drei Grad niedriger war als heute. "

For theoretical neurobiologist and author Mark Changizi, "why" has always been more interesting than "how." While many scientists focus on the mechanics of how we do what we do, his research aims to grasp the ultimate foundations underlying why we think, feel and see as we do. Guided by this philosophy, he has made important discoveries on why we see in color, why we see illusions, why we have forward-facing eyes, why letters are shaped as they are, why the brain is organized as it is, why animals have as many limbs and fingers as they do, and why the dictionary is organized as it is.

"He then asked a bunch of radiologists to review the slides of lungs for cancerous nodules. He wanted to see if they would notice a gorilla the size of a matchbook glaring angrily at them from inside the slide. But they didn't: 83 percent of the radiologists missed it, Drew says. This wasn't because the eyes of the radiologists didn't happen to fall on the large, angry gorilla. Instead, the problem was in the way their brains had framed what they were doing. They were looking for cancer nodules, not gorillas. "They look right at it, but because they're not looking for a gorilla, they don't see that it's a gorilla," Drew says. In other words, what we're thinking about - what we're focused on - filters the world around us so aggressively that it literally shapes what we see"

SETILive is taking the Search for Extraterrestrial Intelligence (SETI) directly to you by presenting radio frequency signals LIVE from the SETI Institute's Allen Telescope Array (ATA) while it's pointed at stars that, based on Kepler exoplanet discoveries, have the best chances of being home to an alien civilization. We'll also be putting you "in the loop" where if enough of you see a potential extraterrestrial (ET) signal in the same data, then within minutes, the ATA will be interrupted and sent back to take a second look. The data you see will be from frequencies where human-made Radio Frequency Interference (RFI) crowds them and we believe the human eye will have a better chance than SETI's computer algorithms to find ET signals there.

"Temperatur-Sturz in der Antike Wie Nof und seine Kollegen im Journal of Paleolimnology (DOI: 10.1007/s10933-005-1996-1) berichten, kam es in der Region um den See Kinneret - dem biblische See Genezareth bzw. dem Galiläischen Meer - in den letzten 12.000 Jahren wahrscheinlich immer wieder zu überraschenden Eisbildungen. Zwar, so Nof, ist es in der jüngeren Geschichte dort nicht mehr zu solchen Wetter-Phänomenen gekommen. Vor 1500 bis 2500 Jahren, als die Atmosphären-Temperatur mindestens drei Grad niedriger lag als heute, war das aber sehr wahrscheinlich immer wieder der Fall. Die Ursache für die immer wieder auftretende Eisbildung hängt mit Besonderheiten des Galiläischen Meeres zusammen. "

We make decisions every day based on the visible world around us. Yet much of our lives is shaped by what we can't see. Jessica Green wants people to see the important role microbes, ecology and evolution play in every facet of our lives. "Touring a building with Jessica Green can be an unsettling experience. "We live nearly 90 percent of our lives indoors, but we know almost nothing about that environment.""

"Researchers in Spain have found that at least some of the individuals claiming to see the so-called aura of people actually have the neuropsychological phenomenon known as "synesthesia" (specifically, "emotional synesthesia"). This might be a scientific explanation of their alleged ability."

The brain's visual neurons continually develop predictions of what they will perceive and then correct erroneous assumptions as they take in additional external information, according to new research done at Duke University.

""You'll see I wear only gray or blue suits," he said. "I'm trying to pare down decisions. I don't want to make decisions about what I'm eating or wearing. Because I have too many other decisions to make." He mentioned research that shows the simple act of making decisions degrades one's ability to make further decisions. It's why shopping is so exhausting. "You need to focus your decision-making energy. You need to routinize yourself. You can't be going through the day distracted by trivia." The self-discipline he believes is required to do the job well comes at a high price. "You can't wander around," he said. "It's much harder to be surprised. You don't have those moments of serendipity."

"How many mammal species live in the forest? It sounds like a simple question, but the actual distributions of shy, small or rare mammals are often murky, confounding conservationists seeking to protect them. Yet a paper published online on Tuesday in the journal Molecular Ecology explores a new way to track biodiversity: by capturing flies that feed on carcasses. The flies' stomachs offer DNA diaries of their recent meals, giving scientists clues to which animals live and die in the forest. "The animals are there, but you just don't see them," said Fabian Leendertz, a wildlife epidemiologist at the Robert Koch Institute in Berlin and an author of the paper. "Those flies will find them and will tell us what is there"

"Regardless of the platform, social media interactions require two-way conversations (see Box 2). Joining one of the many preexisting scientific conversations can simultaneously disseminate your own content, expand your online network, and raise your professional visibility. An easy entry point is the ScienceOnline conglomerate (http://scienceonline.com), an enthusiastic group of science communicators ranging from tenured professors to freelance journalists "

"My link was shared by Bora Zivkovic, whose network is immense. And in turn, the link was shared by Twitter users in Greece, Germany, Belgium and throughout the United States. In the end, the blogpost wound up with 109 readers on January 22nd - with about 50 via Twitter, 26 via Facebook, and others via LinkedIn and elsewhere. When each person shared the link with her or his network, the momentum is carried forward, pushing out to new networks and new degrees of separation. Social sharing is a bit like the emails you would get forwarded by your relatives (you know, those emails). The deeper you scroll down the thread, the less sender names you recognize. But with Twitter, and using analytics like WordPress or Google, you can actually trace how a little link travels through different social networks, and eventually back to your website. Also, because many people embed a small bio or website link in their Twitter profile, I can quickly see who has retweeted and read my link. I can read their tweets to get an idea of their profession and passions,"
