UN moves to strengthen digital privacy (Update)
The United Nations on Tuesday adopted a resolution on protecting digital privacy that for the first time urged governments to offer redress to citizens targeted by mass surveillance.
Two good things that are better together: STM combined with X-ray synchrotron microscopy
(Phys.org) —Over the past three decades, scanning tunneling microscopy (STM) has rapidly become a major component of the condensed matter physics toolbox. While STM can provide vast quantities of data about ...
Carbon nanotube film restores light sensitivity to blind retinas
NASA sees Tropical Storm Nuri resemble a frontal system
NASA's Terra satellite passed over Tropical Storm Nuri on Nov. at captured an infrared picture of the storm. The storm looked more like a frontal system as it stretched from northeast to southwest.
Sources of the solar wind
The solar chromosphere is the region between the Sun's surface and its hot, million-degree corona. Within this complex interface zone, only a few thousand kilometers deep, the density of the gas drops by ...
New microscope collects dynamic images of the molecules that animate life
Over the last decade, powerful new microscopes have dramatically sharpened biologists' focus on the molecules that animate and propel life. Now, a new imaging platform developed by Eric Betzig and colleagues ...
Peering deep inside nongraphitic anodes with synchrotron microtomography
(Phys.org) —With so much of our 21st century technology dependent on ever smaller and more efficient re-chargeable lithium-ion (Li-ion) batteries, finding new ways to non-destructively peer inside an operating ...
What does the next generation telescope need to detect life?
Almost 2,000 extrasolar planets have been discovered to date and this number is constantly increasing. Yet, we still know little about these alien worlds, especially their atmospheres. The atmospheres of ...
A new imaging approach for monitoring cell metabolism
Scientists at EPFL have used a new imaging technique to monitor how glucose, our main energy source, is used in the body. Their findings may have great implications for diseases like diabetes.
Extremely high-resolution magnetic resonance imaging
For the first time, researchers have succeeded to detect a single hydrogen atom using magnetic resonance imaging, which signifies a huge increase in the technology's spatial resolution. In the future, single-atom ...
User-friendly electronic 'EyeCane' enhances navigational abilities for the blind
White Canes provide low-tech assistance to the visually impaired, but some blind people object to their use because they are cumbersome, fail to detect elevated obstacles, or require long training periods ...
Researchers capture images of the elusive protein HIV uses to infect cells
HIV is adept at eluding immune system responses because the protein it uses to infect cells is constantly changing.
MOM eyes the limb of Mars after historic arrival
India's maiden interplanetary voyager, the Mars Orbiter Mission (MOM) has transmitted a breathtaking new image eyeing the limb of Mars and its atmosphere against the blackness of space.
A refined approach to proteins at low resolution
Membrane proteins and large protein complexes are notoriously difficult to study with X-ray crystallography, not least because they are often very difficult, if not impossible, to crystallize, but also because ...
