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.....»»
"Hindcasting" helps identify causes of induced earthquakes in Delaware Basin
Using a method that works backward from a set of observed earthquakes to test seismic models that fit those observations, researchers working in the Delaware Basin were able to determine whether earthquakes in the region since 2017 were caused by oil.....»»
Collecting a library of bee genomes
The USDA Agricultural Research Service is leading a project dubbed "Beenome100" to produce high-quality maps of the genomes of at least 100 bee species, capturing the diversity of bees in the United States, representing each of the major bee taxonomi.....»»
Track-and-trace method predicts best possible resolution in microscopy
TU Delft scientists provide insight into the limitations of super-resolution microscopy and offer a new calculation method to determine maximum resolution. The technology is important for studying processes in the living cell, discovering the origin.....»»
Australia"s first marine Aboriginal archaeological site questioned
A new study from The University of Western Australia has challenged earlier claims that Aboriginal stone artifacts discovered off the Pilbara coast in Western Australia represent Australia's first undisturbed underwater archaeological site......»»
Remote sensing helps track carbon storage in mangroves
Mangrove forests store huge amounts of carbon but figuring out how much is stored globally is challenging. Now, researchers from Japan have developed a new model that uses remote sensing of environmental conditions to determine the productivity of ma.....»»
Arizona fires sweep land rich with ancient sites, artifacts
As Jason Nez scans rugged mountains, high desert and cliffsides for signs of ancient tools and dwellings unique to the U.S. Southwest, he keeps in mind that they're part of a bigger picture......»»
More digging needed to determine whether bones of fallen Waterloo soldiers were sold as fertilizer
Were the bones of fallen Battle of Waterloo soldiers sold as fertilizer?.....»»
X-ray imaging reveals why this 17th century painted yellow rose lost its luster
Researchers combined chemical, optical imaging to determine how degradation occurred. Enlarge / The pigments used to create the yellow rose in Abraham Mignon's Still Life with Flowers and a Watch have degraded, giving the rose a flatte.....»»
China"s lunar lander finds evidence of native water on moon
Samples from the Moon's Oceanus Procellarum, an ancient mare basalt whose name translates to "Ocean of Storms," may be able to help determine the source of lunar water......»»
Nanoparticle sensor can distinguish between viral and bacterial pneumonia
Many different types of bacteria and viruses can cause pneumonia, but there is no easy way to determine which microbe is causing a particular patient's illness. This uncertainty makes it harder for doctors to choose effective treatments because the a.....»»
Helium pre-exposure inhibits hydrogen isotope permeation in wall materials
A research team from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS) has recently revealed that helium exposure could inhibit the penetration of hydrogen isotopes in wall materials. Their results were publish.....»»
With cryo-EM, scientists determine structure of key factor in RNA quality control
In biology, getting rid of stuff can be just as important as making it. A buildup of cells, proteins, or other molecules that are no longer needed can cause problems, so living things have evolved several ways to clean house......»»
New clues about how hot Jupiters form
Since the first hot Jupiter was discovered in 1995, astronomers have been trying to figure out how the searing-hot exoplanets formed and arrived in their extreme orbits. Johns Hopkins University astronomers have found a way to determine the relative.....»»
Investigating the magnetic properties of helium-3
In a joint experimental-theoretical study published in Nature, physicists at the Heidelberg Max Planck Institute for Nuclear Physics (MPIK), together with collaborators from RIKEN, Japan, investigated the magnetic properties of the isotope helium-3......»»
How do plants know how big to grow?
Organisms grow to fit the space and resources available in their environments, leading to a vast diversity of body sizes and shapes within a population of the same species. What are the genetic and physiological mechanisms that determine how big an o.....»»
Unfreezing waters in ligand binding sites to aid in drug discovery
Cryogenic (frozen) protein structures are central to understanding function and developing drugs. Scientists at St. Jude Children's Research Hospital have created an algorithm to reveal when freezing the proteins may create "artifacts,"—errors that.....»»
Machine learning helps determine health of soybean fields
Using a combination of drones and machine learning techniques, researchers from The Ohio State University have recently developed a novel method for determining crop health and used it to create a new tool that may aid future farmers......»»
Sizzling sound of deep-frying reveals complex physics
Experienced cooks can determine when cooking oil has reached the right temperature for deep-frying by inserting moistened chopsticks in the hot oil. Bubbles form on the sticks and the sizzling sound they produce can tell the cook when it is time to a.....»»
All wound up: A reversible molecular whirligig
Over the last few decades, researchers have built minuscule molecular machines that rotate or shuttle other molecules. However, it's difficult to determine the mechanical work and forces that these tiny contraptions produce, which is important when u.....»»
GV60 EV rollout brought Genesis and a new dealer together
To determine distribution, sales and marketing of the GV60 electric crossover, Genesis Motor took the unusual route of partnering with an established dealer of electrified vehicles for guidance......»»
