Capturing a cosmogenic isotope to determine the age of artifacts
You may probably wonder how archaeologists determine the age of ancient artifacts or how long a piece of rock exists above the surface. Isotopic dating can tell the age covering hundreds of thousands of years. For instance, common carbon isotope 14C.....»»
Characterizing atomic defects in 2D materials to determine suitability as quantum emitters
The term molybdenum disulfide may sound familiar to some car drivers and mechanics. No wonder: the substance, discovered by U.S. chemist Alfred Sonntag in the 1940s, is still used today as a high-performance lubricant in engines and turbines, but als.....»»
Researchers develop field identification process for invasive reeds
A team of researchers recently set out to determine whether it is possible to identify invasive common reed reliably in the field—reducing the need for time-consuming and costly genetic testing. In a study featured in Invasive Plant Science and Man.....»»
Affordable Web Hosting for Small Business: Boost Your Success
If you’re on a hunt to chose the best web hosting for your small business, you’ve probably realized that tons of companies are providing this service – and each offering a different set of features. And in a bid to determine which of the availa.....»»
Mammal bites dinosaur in "once-in-a-lifetime" fossil find
A badger-like mammal was sinking its teeth into the ribs of a dinosaur three times its size when they were buried in volcanic ash 125 million years ago, capturing the pair in a deadly embrace......»»
An even closer look at the "doubly magic" tin-100 nucleus
In a new paper published in Physical Review Letters, researchers working at CERN's ISOLDE facility describe how an upgrade to the ISOLTRAP experiment has allowed them to determine the energy necessary to bring the atomic nucleus of indium-99 from its.....»»
Archaeologists in Louisiana save artifacts 12,000 years old from natural disasters and looters
Long buried under the woods of west central Louisiana, stone tools, spearpoints and other evidence of people living in the area as long as 12,000 years ago have become more exposed and vulnerable, due to hurricanes, flooding and looters......»»
Archaeologists in Louisiana save artifacts dating back 12,000 years from natural disasters, looters
Long buried under the woods of west central Louisiana, stone tools, spearpoints and other evidence of people living in the area as long as 12,000 years ago have become more exposed and vulnerable, due to hurricanes, flooding and looters......»»
Biologists determine that blind cavefish cells are responsive to light
A team of marine biologist from James Cook University and University College London has found that blind cavefish living in dark caves in Mexico produce cells that are responsive to light. In their paper published in the journal Proceedings of the Ro.....»»
Capturing the immense potential of microscopic DNA for data storage
In a world first, a "biological camera" bypasses the constraints of current DNA storage methods, harnessing living cells and their inherent biological mechanisms to encode and store data. This represents a significant breakthrough in encoding and sto.....»»
Researchers invent trap for capturing and comparing individual bacterial cells
All hospitals battle an invisible threat: Pseudomonas aeruginosa. It is a type of bacteria that affects thousands of patients each year in intensive care units, where it can cause sepsis, pneumonia and other types of infections......»»
Ice stupas have become a popular water management tool in the Himalayas, but can they work in Chile?
Every winter across the Himalayas for decades, human-made reservoirs have been capturing glacial meltwater from streams and preserving it in the form of ice. By slowing meltwater down or spraying it into the air, people cause it to refreeze, often in.....»»
Testing of wind sensing in rats shows sub-orbital whiskers play a role in assessing direction
A team of neurobiologists and neuroscientists at the Woods Hole Marine Biological Laboratory has found that sub-orbital whiskers play a role in helping rats determine which direction air movement is coming from and to respond accordingly. In their pa.....»»
Scientists synthesize isotopic atropisomers based on carbon isotope discrimination
In chemistry, a molecule or ion is said to be chiral if it cannot be superposed on to its mirror image by any combination of rotations, translations, or conformational changes. A chiral molecule or ion exists in two forms, called enantiomers, that ar.....»»
Tombs rich in artifacts discovered by Swedish expedition in Cyprus
An archaeological expedition from the University of Gothenburg recently discovered tombs outside the Bronze Age trading metropolis Hala Sultan Tekke in Cyprus. They rank among the richest ever found in the Mediterranean region. The precious tomb arti.....»»
Giant stone artifacts found on rare Ice Age site in Kent
Researchers at the UCL Institute of Archaeology have discovered some of the largest early prehistoric stone tools in Britain......»»
Black hole ripples could help pin down expansion of universe
The echoes of light from jets launched from black holes offers a new way to pin down the distance to these exotic objects and to study a largely unobserved population in the center of the Galaxy. It could also even help determine the rate of expansio.....»»
Urine tests identify brain tumors by capturing cancer DNA using nanowires
A group led by researchers at Nagoya University in Japan has developed a technology to capture and release cell-free DNA (cfDNA) on nanowire surfaces from urine. By extracting this DNA, they were able to successfully detect IDH1 mutation, a character.....»»
New study evaluates uncertainties in modeling El Niño-related changes in atmospheric circulation
A research team from the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences has examined the performance of eight prominent reanalysis datasets in capturing regional Hadley Circulation (HC) responses to El Niño–Southern Osci.....»»
Study offers strategy for green synthesis of 15N-amino acids
15N isotope-labeled amino acids (15N-amino acids) provide a safe and effective tracer tool for studying the synthesis of natural products, protein metabolism, and disease diagnosis and treatment in living organisms. In addition, it is an important sy.....»»
New criteria to determine whether shear bands are beneficial or harmful to crystalline materials
Shear band formation is not typically a good sign in a material—the bands often appear before a material fractures or fails. But materials science and engineering researchers at the University of Wisconsin–Madison have found that shear bands aren.....»»
