Water discovered in remnants of extrasolar rocky world orbiting white dwarf Posted: 10 Oct 2013 11:27 AM PDT Astrophysicists have found the first evidence of a water-rich rocky planetary body outside our solar system in its shattered remains orbiting a white dwarf.

Laser technique enables 3-D analysis and natural color images Posted: 10 Oct 2013 09:43 AM PDT A new technology invented to automate the laborious process of preparing plant roots for phenotyping has morphed into a powerful tool for exploring the three-dimensional structure of small objects.

'Ship in a bottle' detects dangerous vapors: Scientists trap metallic compounds to sniff out signs of hazardous solvents Posted: 10 Oct 2013 07:50 AM PDT Scientists took a lesson from craftsmen of old to assemble microscopic compounds that warn of the presence of dangerous fumes from solvents.

Gene movements observed in vivo Posted: 10 Oct 2013 07:50 AM PDT Certain parts of DNA are highly mobile and their dynamic motion participates in controlling gene expression. Scientists have just developed a method of observing the organization and movements of the genome in time and space. The researchers succeeded in marking then monitoring parent genes during cell division.

Soft shells and strange star clusters Posted: 10 Oct 2013 06:16 AM PDT The beautiful, petal-like shells of galaxy PGC 6240 are captured here in intricate detail by the NASA/ESA Hubble Space Telescope, set against a sky full of distant background galaxies. This cosmic bloom is of great interest to astronomers due to both its uneven structure, and the unusual clusters of stars that orbit around it -- two strong indications of a galactic merger in the recent past.

Direct 'writing' of artificial cell membranes on graphene Posted: 10 Oct 2013 06:16 AM PDT Graphene emerges as a versatile new surface to assemble model cell membranes mimicking those in the human body, with potential for applications in sensors for understanding biological processes, disease detection and drug screening.

Guardrail barrier made with Mediterranean tapeweed residues Posted: 10 Oct 2013 06:14 AM PDT Researchers have developed a guardrail barrier from seagrass residues in order to minimize the risk of injuries on roads.

Several top websites use device fingerprinting to secretly track users Posted: 10 Oct 2013 06:14 AM PDT A new study has uncovered that 145 of the Internet's 10,000 top websites track users without their knowledge or consent. The websites use hidden scripts to extract a device fingerprint from users' browsers. Device fingerprinting circumvents legal restrictions imposed on the use of cookies and ignores the Do Not Track HTTP header. The findings suggest that secret tracking is more widespread than previously thought.

Technique enables accurate, hands-free measure of heart, respiration rates Posted: 08 Oct 2013 03:23 PM PDT A simple video camera paired with complex algorithms appears to provide an accurate means to remotely monitor heart and respiration rates day or night, researchers report.

Flawed diamonds: Gems for new technology Posted: 08 Oct 2013 01:54 PM PDT Scientists have made the first detailed observation of how energy travels through diamonds that contain nitrogen-vacancy centers. The unexpected and attractive properties of these "flawed" diamonds put them in the spotlight as promising candidates for a variety of technological advances.
