Researchers have developed a new measurement and imaging approach that can resolve nanostructures smaller than the diffraction limit of light without requiring any dyes or labels. The work represents… [+3960 chars]
To get to the places where they are needed, immune cells not only squeeze through tiny pores. They even overcome wall-like barriers of tightly packed cells. Scientists at the Institute of Science and… [+4699 chars]
It is well known that global warming is causing sea levels to rise via two processes: thermal expansion, when water expands because of its increased temperature, and melting of land-based ice, when m… [+2431 chars]
The NIST team directed light into an ultrathin layer of silicon nitride etched with grooves to create a diffraction grating. If the separation between the grooves and the wavelength of light is caref… [+6054 chars]

NASA has developed a new metal alloy using a 3D printing process that can dramatically improve the strength and durability of the components and parts used in aviation and space exploration, resultin… [+2030 chars]
After more than a year of accomplishments, NASA has extended flight operations for the Mars Innovation helicopter through September. The space agency’s $2.2 billion spacecraft touched down on Mars … [+3281 chars]
Gloopy goo that fatally snared spiders more than 22 million years ago may have also helped preserve them in exquisite detail. Key points: <ul><li>Soft-bodied animals such as spiders and insects ten… [+6344 chars]
A new survey of over 100 galaxies has found that black holes raze thousands of stars and use their remains to pack on weight. This discovery, made with NASA's Chandra X-ray Observatory, could help ex… [+1729 chars]
The U-shaped relationship between diet and size in modern land mammals could also stand for “universal,” says a new study, which has found that the relationship spans at least 66 million years and a … [+7412 chars]
At the Scripps Institution of Oceanography at UC San Diego, an international research group made use of computer model simulations to determine that climate change is changing the mechanics of surfac… [+3355 chars]
Even more information can be gained from those pterosaur feathers. The study indicates they were fairly small, meaning that they weren't used to help the animal fly. Instead, the feathers could have … [+1242 chars]
