Quantum Imaging: Scattered Observations On "Copenhagen"

People divulge more sensitive information on sites that look less safe.

Researchers at Carnegie Mellon University have found that the appearance of website has a big effect on how honestly people answer personal questions put to them by the site. But paradoxically, it turns out we're more likely to spill our secrets on websites that appear less reputable. The way a website phrases questions also affects our willingness to disclose revealing information, the researchers found.

NudgeCam encourages good footage by tracking faces and assessing sound quality.

If you've ever accidentally shot a video sideways, or cropped the top of someone's head out of a frame, you might be glad to know about a new cell-phone app that automatically provides shooting advice to videographers.

A computer model that detects who is influencing whom in a group discussion, can accurately predict who is likely to speak next

One fascinating question that occupies social scientists concerns groups discussions. The problem is to determine the nature of the interaction between individuals and in particular, who influences whom.

Millions of Web surfers have spare computer cycles--why not use browsers to tap them?

Unless a flash ad in one of your open browser tabs has gone rogue, it's likely you've got a few spare processor cycles available on the PC you're using to read this.

The largest-ever storm monitoring mission is now gathering scientific data that was previously impossible to get.

As Hurricane Earl barrels toward the eastern seaboard of the United States, coastal residents don't know if they should evacuate in case the storm makes landfall. They rely on forecasters analyzing computer models, but those predictions differ. A new hurricane-monitoring mission that's now underway hopes to reduce this uncertainty by gathering atmospheric and environmental storm data never before obtained.

The next few years will see at least two new commercial spacecraft put into orbit.

A small fleet of privately developed spacecraft will head into orbit in the next few years--assuming that current levels of public and private funding can be sustained. If it happens, this will mark a new chapter in space exploration and research, as NASA comes to rely more on private companies for the technology to put manned and unmanned vehicles in space.

Scientists examine new ways to manipulate the microorganisms within us.

Earlier this summer, scientists reported the success of an unusual medical transplant; a woman with a life-threatening Clostridium difficile infection was treated, and apparently cured, with an injection of some of her healthy husband's gut bacteria. Researchers are now exploring the effects of this type of transplant in greater detail. They hope to eventually treat a wide range of ailments--from bowel diseases to obesity, diabetes to depression--by manipulating the bacteria that live in the human gut.

A new way of excavating the past structure of networks reveals important information about their evolution

The agency announced its latest revision but budget uncertainties in the U.S. Congress make plans moving targets.
