First Glowing Reptile

September 29, 2015 2:30 pm | by Greg Watry, Digital Reporter | Articles | Comments

On a July night, marine biologist David Gruber was scuba diving in the Solomon Islands, documenting corals and creatures known for their biofluorescence. Slime neon greens and subtle reds can be seen in video footage from National Geographic. Around 40 min into the dive, Gruber saw an unexpected entity glowing in the dark waters.


Physicists map the strain in a wonder material

September 29, 2015 2:02 pm | by Kurt Pfitzer, Lehigh Univ. | News | Comments

An international group of scientists reports a breakthrough in the effort to characterize the properties of graphene noninvasively, while acquiring information about its response to structural strain. Using Raman spectroscopy and statistical analysis, the group succeeded in taking nanoscale measurements of the strain present at each pixel on the material's surface.


Chilling/Heating Dry Bath

September 29, 2015 1:15 pm | by Torrey Pines Scientific | Product Releases | Comments

Torrey Pines Scientific has introduced its EchoTherm Model IC50, Peltier-driven, Chilling/Heating Dry Bath with exact sample temperature control. The unit is supplied with a temperature probe to insert directly into the sample or into the sample block. The probe senses the sample temperature or sample block temperature directly and sends that information to the unit to drive and control the temperature exactly where set.


Reaction snapshots of a notch-modifying enzyme provide basis for drug design

September 29, 2015 1:00 pm | by Chelsea Whyte, Brookhaven National Laboratory | Videos | Comments

Notch receptors are core components of the signaling pathways that regulate the development of cells within the human body. Notch signaling pathways can determine how cells proliferate or change during development, and defects in Notch signaling can lead to many diseases, including several types of cancer and developmental disorders.


Creating Fake Teeth as Strong as the Real Deal

September 29, 2015 12:46 pm | by Greg Watry, Digital Reporter | Articles | Comments

As the hardest substance in the human body, enamel covers the crown of a tooth, protecting the sensitive dentine beneath. Each day, teeth are subjected to the chomping and chewing of food substances, from soft bananas to hard candy. According to Live Science, the “basket-weave-like microstructure” of enamel is behind a tooth’s durability.  


Plant debris decomposition tied to manganese

September 29, 2015 12:00 pm | by Anne M Stark, LLNL | News | Comments

The decomposition of plant debris (litter) is a fundamental process that regulates the release of nutrients for plant growth and the formation of soil organic matter in forest ecosystems. A strong correlation has previously been observed between litter manganese (Mn) content and decomposition rates across a variety of forest ecosystems. However, the mechanisms underlying Mn's role in litter decomposition were not well understood.


Ductless Fume Hood

September 29, 2015 11:56 am | by Air Science Inc | Product Releases | Comments

Air Science's PURAIR 5 DuctlessFume Hoods feature a high level of operator protection where routine work is carried out. The units exceed OSHA, ANSI and all relevant international standards. The ductless design eliminates installation costs and allows the unit to be positioned over a sink or benchtop apparatus.

Smaller is better for nanotube analysis

September 29, 2015 11:00 am | by Mike Williams, Rice Univ. | News | Comments

In a great example of “less is more,” Rice Univ. scientists have developed a powerful method to analyze carbon nanotubes in solution. The researchers’ variance spectroscopy technique zooms in on small regions in dilute nanotube solutions to take quick spectral snapshots.


Reason Behind Comet’s Rubber Duck Shape Revealed

September 29, 2015 10:55 am | by Greg Watry, Digital Reporter | Articles | Comments

It’s a grey rubber duck floating in the universe’s bathtub. In July 2014, the European Space Agency (ESA)’s Rosetta probe gleaned the shape of Comet 67P/Churyumov-Gerasimenko, or Rosetta’s Comet, for the first time. Scientists were surprised by the nucleus’ twin-lobbed form. Though not uncommon, dual objects are theorized to form when two comets collide.


First optical rectenna converts light to DC current

September 29, 2015 10:00 am | by John Toon, Georgia Institute of Technology | Videos | Comments

Using nanometer-scale components, researchers have demonstrated the first optical rectenna, a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC current. Based on multiwall carbon nanotubes and tiny rectifiers fabricated onto them, the optical rectennas could provide a new technology for photodetectors that would operate without the need for cooling.


Five Reasons Why R&D Labs Should Use Industrial CT Scanning

September 29, 2015 9:30 am | by Visent Avxhi, Business Unit Manager, 3D ProScan | Articles | Comments

Here are the five major reasons why R&D laboratories should use industrial CT scanning: whole part analysis in 1 hr, faster validations, non-destructive analysis, no fixtures required and free viewing software.


Four Ways to Better Water Quality in LC-MS

September 29, 2015 8:32 am | by Anastasia Khvataeva-Domanov and Stephane Mabic, Millipore S.A.S. | Articles | Comments

High-purity water is key to the success of analyses performed using (ultra) high-performance liquid-chromatography-mass spectrometry, (U)HPLC-MS, also known as LC-MS. Even so, chromatographers may consciously select top-quality salts and organic solvents for mobile phase preparation, but not apply the same level of care when choosing their source of high-purity water.


Unique self-assembling material could lead to artificial arteries

September 29, 2015 7:56 am | by Will Hoyles, Public Relations Manager, Queen Mary Univ. of London | News | Comments

Researchers at Queen Mary Univ. of London have developed a way of assembling organic molecules into complex tubular tissue-like structures without the use of molds or techniques like 3-D printing. The study, which appears in Nature Chemistry, describes how peptides and proteins can be used to create materials that exhibit dynamic behaviors found in biological tissues like growth, morphogenesis and healing.


A light touch

September 29, 2015 7:48 am | by Byron Spice, Carnegie Mellon Univ. | News | Comments

Optical sensors may be uniquely suited for use in robotic hands, according to Carnegie Mellon Univ. researchers who have developed a three-fingered soft robotic hand with multiple embedded fiber optic sensors. They also have created a new type of stretchable optical sensor.


Goods manufactured in China aren’t good for the environment

September 29, 2015 7:44 am | by Brian Bell, Univ. of California, Irvine | News | Comments

In a study published in Nature Climate Change, scientists from three universities show that products made in China are associated with significantly higher carbon dioxide emissions than the same products made elsewhere.
