World's smallest liquid droplets ever made in the lab, experiment suggests Posted: 16 May 2013 05:06 PM PDT Physicists may have created the smallest drops of liquid ever made in the lab. That possibility has been raised by the results of a recent experiment at the Large Hadron Collider, the world's largest and most powerful particle collider located at the European Laboratory for Nuclear and Particle Physics (CERN) in Switzerland. Evidence of the minuscule droplets was extracted from the results of colliding protons with lead ions at velocities approaching the speed of light.

Stacking 2-D materials produces surprising results Posted: 16 May 2013 03:20 PM PDT New experiments reveal previously unseen effects, could lead to new kinds of electronics and optical devices.

Galaxy's 'burning ring of fire' is frenetic region of star formation Posted: 16 May 2013 01:53 PM PDT Johnny Cash may have preferred this galaxy's burning ring of fire to the one he sang about falling into in his popular song. The "starburst ring" seen at center of a new image in red and yellow hues is not the product of love, as in the song, but is instead a frenetic region of star formation. The galaxy, a spiral beauty called Messier 94, is located about 17 million light-years away.

New method proposed for detecting gravitational waves from ends of universe Posted: 16 May 2013 01:17 PM PDT A new window into the nature of the universe may be possible with a device proposed by scientists that would detect elusive gravity waves from the other end of the cosmos.

Change in cycle track policy needed to boost ridership, public health Posted: 16 May 2013 01:16 PM PDT Bicycle engineering guidelines often used by state regulators to design bicycle facilities need to be overhauled to reflect current cyclists' preferences and safety data, according to a new study. They say that US guidelines should be expanded to offer cyclists more riding options and call for endorsing cycle tracks -- physically separated, bicycle-exclusive paths adjacent to sidewalks -- to encourage more people of all ages to ride bicycles.

Can math models of gaming strategies be used to detect terrorism networks? Posted: 16 May 2013 11:26 AM PDT Mathematicians have developed a mathematical model to disrupt the flow of information in a complex real-world network, such as a terrorist organization, using minimal resources.

Artificial forest for solar water-splitting: First fully integrated artificial photosynthesis nanosystem Posted: 16 May 2013 11:26 AM PDT Researchers have created the first fully integrated artificial photosynthesis nanosystem. While "artificial leaf" is the popular term for such a system, the key to this success was an "artificial forest."

Beautiful 'flowers' self-assemble in a beaker Posted: 16 May 2013 11:22 AM PDT With the hand of nature trained on a beaker of chemical fluid, the most delicate flower structures have been formed in a laboratory -- and not at the scale of inches, but microns. These minuscule sculptures, curved and delicate, don't resemble the cubic or jagged forms normally associated with crystals, though that's what they are. Rather, fields of carnations and marigolds seem to bloom from the surface of a submerged glass slide, assembling themselves a molecule at a time.

DNA-guided assembly yields novel ribbon-like nanostructures Posted: 16 May 2013 09:39 AM PDT DNA "linker" strands coax nano-sized rods to line up in way unlike any other spontaneous arrangement of rod-shaped objects. The arrangement -- with the rods forming "rungs" on ladder-like ribbons -- could result in the fabrication of new nanostructured materials with desired properties.

Security risks found in sensors for heart devices, consumer electronics Posted: 16 May 2013 09:39 AM PDT The type of sensors that pick up the rhythm of a beating heart in implanted cardiac defibrillators and pacemakers are vulnerable to tampering, according to a new study conducted in controlled laboratory conditions.

Engineers monitor heart health using paper-thin flexible 'skin' Posted: 16 May 2013 07:57 AM PDT Engineers combine layers of flexible materials into pressure sensors to create a wearable heart monitor thinner than a dollar bill. The skin-like device could one day provide doctors with a safer way to check the condition of a patient's heart.

New insights into how materials transfer heat could lead to improved electronics Posted: 16 May 2013 07:56 AM PDT Researchers have published new insights into how materials transfer heat, which could lead eventually to smaller, more powerful electronic devices.

Weather on the outer planets only goes so deep Posted: 16 May 2013 07:56 AM PDT What is the long-range weather forecast for the giant planets Uranus and Neptune? These planets are home to extreme winds blowing at speeds of over 1000 km/hour, hurricane-like storms as large around as Earth, immense weather systems that last for years and fast-flowing jet streams. Researchers set an upper limit for the thickness of jet streams on Uranus and Neptune.

Moth-inspired nanostructures take the color out of thin films Posted: 16 May 2013 07:56 AM PDT Inspired by the structure of moth eyes, researchers have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film interference" phenomenon commonly observed in nature. This can potentially improve the efficiency of thin-film solar cells and other optoelectronic devices.

3-D modeling technology offers groundbreaking solution for engineers Posted: 16 May 2013 07:56 AM PDT New software has the potential to enable engineers to make 'real world' safety assessments of structures and foundations with unprecedented ease.

Carbon in a twirl: The science behind a self-assembled nano-carbon helix Posted: 16 May 2013 07:55 AM PDT Nanotechnology draws on the fabrication of nanostructures. Scientists have now succeeded in growing a unique carbon structure at the nanoscale that resembles a tiny twirled mustache. Their method might lead the way to the formation of more complex nano-networks.

Asteroid 1998 QE2 to sail past Earth is nine times larger than cruise ship Posted: 16 May 2013 06:53 AM PDT On May 31, 2013, asteroid 1998 QE2 will sail serenely past Earth, getting no closer than about 3.6 million miles (5.8 million kilometers), or about 15 times the distance between Earth and the moon. And while QE2 is not of much interest to those astronomers and scientists on the lookout for hazardous asteroids, it is of interest to those who dabble in radar astronomy and have a 230-foot (70-meter) -- or larger -- radar telescope at their disposal.
