In the age of big data, visualization tools are vital. With a single glance at a graphic display, a human being can recognize patterns that a computer might fail to find even after hours of analysis. But what if there are aberrations in the patterns? Or what if there’s just a suggestion of a visual pattern that’s not distinct enough to justify any strong inferences? Or what if the pattern is clear, but not what was to be expected?

There may be itsy-bitsy aliens among us. Scientists say seven microscopic particles collected by NASA's comet-chasing spacecraft, Stardust, appear to have originated outside our solar system. If confirmed, this would be the world's first sampling of contemporary interstellar dust.
A photo is worth a thousand words, but what if the image could also represent thousands of other images? New software seeks to tame the vast amount of visual data in the world by generating a single photo that can represent massive clusters of images. This tool can give users the photographic gist of a kid on Santa’s lap or housecats. It works by generating an image that literally averages the key features of the other photos.

It's easy to go online and get a 360-degree, ground-level view of almost any street in the US and throughout the world. Soon, scientists hope to do the same with coral reefs and other underwater wonders. They are learning to use specialized fisheye lenses underwater in the Florida Keys in hopes of applying "street view" mapping to research and management plans in marine sanctuaries nationwide. Some of the images will be available online...
Journalist and scientific organizations accused the EPA of attempting to muzzle its independent scientific advisers by directing them to funnel all outside requests for information through agency officials. In a letter on August 12, 2014, groups representing journalists and scientists urged the EPA to allow advisory board members to talk directly to news reporters, Congress and other outside groups without first asking for permission.

Just about everything you ever wanted to know about quantum simulators is summed up in a new review. As part of a Thematic Series on Quantum Simulations, the open access journal European Physical Journal Quantum Technology has published an overview of just what a quantum simulator is, namely a device that actively uses quantum effects to answer questions on model systems.
Tate Britain is inviting art fans to a night at the museum — though robots, not T. rexes, will be roaming this time. The London art museum says, for five nights beginning August 12, 2014, people from around the world can get an after-hours tour online thanks to four roaming robots fitted with lights, cameras and sensors designed to let them move around the rooms in the dark.
A NASA-led team of scientists has created detailed 3-D maps of the atmospheres surrounding comets, identifying several gases and mapping their spread at the highest resolution ever achieved. Almost unheard of for comet studies, the 3-D perspective provides deeper insight into which materials are shed from the nucleus of the comet and which are produced within the atmosphere, or coma.
On July 26, 2014, from 10:57 a.m. to 11:42 a.m. EDT, the moon crossed between NASA’s Solar Dynamics Observatory (SDO) and the sun, a phenomenon called a lunar transit. A lunar transit happens approximately twice a year, causing a partial solar eclipse that can only be seen from SDO's point of view.
LabVIEW 2014 system design software standardizes the way users interact with hardware through reuse of the same code and engineering processes across systems, which scales applications for the future. This saves time and money as technology advances, requirements evolve and time-to-market pressure increases.
High-tech specks called quantum dots could bring brighter, more vibrant color to mass market TVs, tablets, phones and other displays.
