Rare discovery of new fatty acids

Posted: 27 Aug 2018 11:04 AM PDT

Decades after scientists discovered hundreds of different fatty acids in vegetable oils, two that had managed to elude detection have finally revealed themselves. The discovery may be the first of its kind since the 1960s and 1970s, the researchers said, when biochemists identified troves of new fatty acids in various vegetable oils.


Nano-imaging of intersubband transitions in few-layer 2-D materials

A study reports on the first observation of intersubband transitions in 2-D materials via scattering scanning near-field optical microscopy.


This bright blue dye is found in fabric: Could it also power batteries?

Posted: 27 Aug 2018 10:44 AM PDT

Methylene blue is a common ingredient in wastewater from textile mills. But scientists think it may be possible to give this industrial pollutant a second life. In a study, they show that the dye, dissolved in water, is good at storing and releasing energy on cue. This makes the compound a promising material for redox flow batteries, which could store energy for wind farms and solar homes.


Massive effort yields image-based cell sorting technology

Posted: 27 Aug 2018 09:13 AM PDT

Invented over 50 years ago, flow cytometry-based cell sorting has become a widely used tool in biology labs for physically isolating cells based on their global surface marker expression profiles. But now researchers have unveiled the next evolution in this critical process, ‘Image-Activated Cell Sorting,’ or IACS for short.


Serendipitous discovery may lead to eco-friendly lubricant

Posted: 27 Aug 2018 09:12 AM PDT

Seed oil components of an ornamental flower could provide a direct pathway for designing a new class of environmentally friendly lubricants. Researchers identified the compound in the seed oil that is produced in a manner unlike any other fatty acid.


Jupiter had growth disorders

Posted: 27 Aug 2018 08:08 AM PDT

Researchers can now show how Jupiter was formed. Data collected from meteorites had indicated that the growth of the giant planet had been delayed for two million years. Now the researchers have found an explanation: Collisions with kilometer-sized blocks generated high energy, which meant that in this phase hardly any accretion of gas could take place and the planet could only grow slowly.




Scientists advance technique for developing novel light beams from synchrotron radiation

Posted: 27 Aug 2018 07:26 AM PDT

Structured light, created using the process of generating and applying light to a surface, is important in many of today’s devices, such as 3D scanners, dual photography and microscopic technology.


Particles give absolute age of asteroid Itokawa

Posted: 27 Aug 2018 07:04 AM PDT

Scientists have closely examined particles collected from the asteroid Itokawa by the spacecraft Hayabusa, finding that the parent body of Itokawa was formed about 4.6 billion years ago when the solar system was born and that it was destroyed by a collision with another asteroid about 1.5 billion years ago.


Water vapor annealing technique on diamond surfaces for next-generation power devices

Posted: 27 Aug 2018 07:04 AM PDT

The existing surface termination technique using hydrogen to stabilize the diamond’s structure for application in electronic power devices results in two-dimensional hole gas layers (2DHG). Attempting to remove these layers using oxygen-termination roughens the diamond surface and leads to degradation of the device performance. To overcome this, researchers removed 2DHG from diamond using water vapor annealing and maintained an atomically flat surface.


Getting a charge out of MOFs

Posted: 27 Aug 2018 06:17 AM PDT

Researchers have made a metal organic framework (MOF) with the highest electron charge mobilities ever observed, along with a technique to improve the conductivity of other MOFs.


In the race of life, the tortoise beats the hare every time

Posted: 27 Aug 2018 05:09 AM PDT

Researchers have discovered that, over the long-run, the race will indeed go to the slower, steadier animal. An analysis of the reported speeds of animals based on land, air and water shows that some of the world’s fastest animals are actually some of the slowest when their movements are averaged throughout their lifetimes, giving credence to Aesop’s fable ‘The Tortoise and the Hare.’


One in 3 US veteran firearm owners keeps a gun loaded and unlocked

Posted: 27 Aug 2018 05:09 AM PDT

One third of United States armed forces veterans store at least one firearm loaded with ammunition and unlocked, according to a new study that reports on the first survey of a nationally representative sample of this group regarding storage practices. Unsafe firearm storage practices appeared to be strongly related to perceptions about the need to keep firearms for protection.
