Researchers have identified 13 metabolites– small molecules produced by cellular metabolism– that are significantly different in patients with diabetes and chronic kidney disease compared to healthy controls.
Queen bees convey honest signals to worker bees about their reproductive status and quality, according to researchers who say their findings may help to explain why honey bee populations are declining.
Some electrons in a superconducting material behave as if they were in a conventional metal, others as in an unconventional one– depending on the direction of their motion.
Scientists have flown through the smoke plumes of wildfires to measure aerosol evolution and map the potential impact on climate change.
Nanoadditives can make plastics scratch- and flame-proof, or give them antibacterial properties. For this to work, the particle distribution within the plastic compound must be absolutely correct. A new device can now test the distribution in real-time.
The recent publication of a new standard provides confidence that results from handheld chemical detectors can be compared, apples-to-apples.
The ever-increasing threat from "superbugs"— strains of pathogenic bacteria that are impervious to the antibiotics that subdued their predecessor generations— has forced the medical community to look for bactericidal weapons outside the realm of traditional drugs.
A huge plastic balloon floated high in the skies over New Mexico, carrying instruments to collect climate-related test data with the help of carbon nanotube chips.
An international team of scientists have identified potentially dangerous amounts of methamphetamine analog in the workout supplement Craze, a product widely sold across the U.S. and online.
The Food and Drug Administration is trying to solve a stubborn mystery surrounding the deaths of almost 600 dogs that ate jerky treats, and officials are hoping pet owners and veterinarians can help them figure out what exactly may be causing the illnesses.
Researchers are working to try to curb the threat that two weed species pose to nurseries, Christmas tree farms, pastures and natural areas.
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 are thinking small, building on decades of sensor work to invent tiny detectors that can sniff out everything from explosives and biotoxins to smuggled humans.
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.
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.
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.
By applying NMR spectroscopy, an international team has solved a long-standing theoretical problem regarding the identification of solvent structures.
Researchers— using a combination of X-ray spectroscopy, liquid microjets and first principles’ theory— have shown that, when hydrated in water, positively charged ions can actually pair up with one another.
Pyrite— better known as fool’s gold— holds promise as a high-tech material. But its potential usefulness in devices is largely influenced by the fundamental electronic properties of its surface— which have remained relatively unexplored.
A new laser technique can discern the contents of used nuclear fuel and potentially boost the global security of nuclear recycling.
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.
