Flawed Diamonds are Gems for New Technology

October 15, 2013 7:00 am | by Univ. of Arizona | News | Comments

Using ultra-fast laser pulses, scientists have made the first detailed observation of how energy travels through diamonds containing nitrogen-vacancy centers– promising candidates for a variety of technological advances such as quantum computing.

Researchers Combine Tunneling Microscopy, Infrared Spectroscopy

October 15, 2013 7:00 am | by Physical Review Letters | News | Comments

A team has succeeded in combining tunneling microscopy and infrared spectroscopy to gain a better understanding of how molecules behave when they stick to a surface. They used a custom built laser to allow for performing infrared spectroscopy with scanning tunneling microscopy without heating its tip.

Urine Test Could Diagnose Eye Disease

October 15, 2013 7:00 am | by Duke Univ. | News | Comments

You might not think to look to a urine test to diagnose an eye disease. But a new study says it can link what is in a patient's urine to gene mutations that cause retinitis pigmentosa, or RP, an inherited, degenerative disease that results in severe vision impairment and often blindness.

Rapid, Paper-Based Test Diagnoses TB

October 15, 2013 7:00 am | by National Institute for Materials Science | News | Comments

In a study, researchers describe a simple, color-based diagnostic approach with the potential to detect target DNA sequences found in TB-causing mycobacteria– in just a fraction of the time required for established diagnostic tests.

Scientists Look to Curb Weed Threat

October 15, 2013 7:00 am | by Agricultural Research Service | News | Comments

Researchers are working to try to curb the threat that two weed species pose to nurseries, Christmas tree farms, pastures and natural areas.

September 5, 2013 7:00 am | by ETH Zurich | News | Comments

Using carbon nanotubes, a research team has developed a sensor that greatly amplifies the sensitivity of commonly used but typically weak vibrational spectroscopic methods, such as Raman spectroscopy.

Method Improves Measurement of Distant Star's Gravity

September 5, 2013 7:00 am | by Vanderbilt Univ. | News | Comments

Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface.

Researchers Gain Better Insight into Molecular Interactions

September 5, 2013 7:00 am | by Helmholtz-Zentrum Berlin | News | Comments

How exactly atoms and molecules interact is a question of great importance. Researchers have now provided a new tool that enables scientists to get a “fingerprint” of the interactions on the atomic scale.

Laser-Induced Spectroscopy Could Aid Nuclear Recycling

September 5, 2013 7:00 am | by Idaho National Laboratory | News | Comments

A new laser technique can discern the contents of used nuclear fuel and potentially boost the global security of nuclear recycling.

Chelyabinsk Meteorite Had Previous Collision

September 4, 2013 2:14 pm | by European Association of Geochemistry | News | Comments

The Chelyabinsk meteorite either collided with another body in the solar system or came too close to the Sun before it fell to Earth. A team has analyzed fragments of the meteorite, the main body of which fell to the bottom of the Chebarkul Lake near Chelyabinsk on February 15 this year.

Scientists Develop LCMS Method for Poisonous Plant

September 4, 2013 2:07 pm | by Kew Gardens | News | Comments

When chemists examined the scientific literature on yew wood chemistry, they found that reports on taxines, particularly taxine B, in heartwood of yew were ambiguous. They developed an LCMS method to detect and handle enquiries.                           

CDC Warns of New Designer Drug

September 4, 2013 12:33 pm | by CDC | News | Comments

Acetyl fentanyl overdose deaths have recently been confirmed in Pennsylvania. If states observe clusters or increases in illicit opioid-related overdoses above expected levels, acetyl fentanyl could be involved. CDC encourages laboratories to use an ELISA test to screen specimens from suspected illicit, nonpharmaceutical opioid overdose deaths. If an ELISA test is positive for fentanyl, CDC recommends confirmatory testing by GCMS.
