Giving transplanted cells a nanotech checkup

Researchers at Johns Hopkins have devised a way to detect whether cells previously transplanted into a living animal are alive or dead, an innovation they say is likely to speed the development of cell replacement therapies ...

Researchers developing faster video streaming

In the smartphones and tablet era, more and more users are watching videos on the move—with a resulting strain on mobile networks. The combination of the HEVC video compression standard with LTE brings networks welcome ...

A spiral galaxy with a secret

(Phys.org)—The NASA/ESA Hubble Space Telescope – with a little help from an amateur astronomer – has produced one of the best views yet of nearby spiral galaxy Messier 106. Located a little over 20 million light-years ...

When the cell's two genomes collide

(Phys.org)—Plant and animal cells contain two genomes: one in the nucleus and one in the mitochondria. When mutations occur in each, they can become incompatible, leading to disease. To increase understanding of such ...

Evidence that at least one mammal can smell in stereo

Most mammals, including humans, see in stereo and hear in stereo. But whether they can also smell in stereo is the subject of a long-standing scientific controversy. Now, a new study shows definitively that the common mole ...

Using single quantum dots to probe nanowires

Modern telecommunications happens because of fast electrons and fast photons. Can it get better? Can Moore's law—the doubling of computing power ever 18 months or so—be sustained? Can the compactness (nm-scale components) ...
