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.....»»
LIBRA: An adaptative integrative tool for paired single-cell multi-omics data
Single-cell multi-omics technologies allow a profound system-level biology understanding of cells and tissues. However, an integrative and possibly systems-based analysis capturing the different modalities is challenging. In response, bioinformatics.....»»
Having a single parent doesn"t determine your life chances. Data shows poverty is far more important
Numerous research studies have suggested that children from a single-parent family are worse off than those who have two parents at home. These findings chime with decades of stigma that have painted coming from a single-parent home as undesirable......»»
How to use the Privacy Shield on Arlo cameras
Many Arlo cameras use a Privacy Shield to physically block the lens from capturing footage. Here's how to activate and deactivate the useful feature......»»
CRONT: Empowering optical tweezers with "biometric eyes"
Optothermal nanotweezers, an innovative optical manipulation technique over the past decade, have revolutionized classical optical manipulation by efficiently capturing a broader spectrum of nanoparticles. While this technique has been primarily used.....»»
Better capturing the effect of aerosol particles on clouds and the climate
The extent to which aerosol particles affect the climate depends on how much water the particles can hold in the atmosphere. The capacity to hold water is referred to as hygroscopicity (K) and, in turn, depends on further factors—particularly the s.....»»
Research provides new methods to improve capture rates of ground-dwelling arthropods using pitfall trapping
Pitfall traps are commonly used for capturing ground-dwelling arthropods, particularly beetles, ants, and spiders. The efficiency of a pitfall trapping system is significantly influenced by the quantity and size of traps, the spatial distribution of.....»»
New plant hardiness map, used by gardeners nationwide, is unveiled
The U.S. Department of Agriculture today released its new Plant Hardiness Zone Map, the national standard by which gardeners can determine which plants are most likely to survive the coldest winter temperatures at a certain location......»»
Feathery moa"s fossilized footprints, ancient age revealed
Cosmogenic nuclide dating, a method commonly used in dating coastal areas and alluvial riverbeds for landscape reconstruction, is also useful for calculating the age of trace fossils, such as a footprint, where no remains of the animal are preserved......»»
Study examines link between underwater landslides and tsunamis
Scientists have calculated a way to determine the speed of past underwater landslides. To do so, researchers from The Ohio State University studied the remains of an underwater landslide just off the coast of Oregon—dubbed the 44-N Slide—that is.....»»

Researchers produce Mo-99 by electron accelerator with optimized target system
Chinese researchers have developed a process for producing the medical isotope molybdenum-99 (Mo-99) using the electron accelerator system. The study was published in Applied Radiation and Isotopes......»»
Cultural artifacts serve as "cognitive fossils," helping uncover the psychology of the past
No two societies in history think exactly alike. In fact, the mindset of a given society throughout history can help historians unpack important clues about the effects of psychological shifts—such as more social trust or more openness......»»
Not the government, but powerful corporations determine climate policy in Brazil
Bribing a politician to gain influence or making sure friends end up in powerful positions: Brazilian energy companies use these power strategies daily. This has a negative effect on Brazil's climate policy, Ph.D. candidate Anaide Ferraço discovered.....»»
Bringing a shark to a knife fight: 7,000-year-old shark-tooth knives discovered in Indonesia
Excavations on the Indonesian island of Sulawesi have uncovered two unique and deadly artifacts dating back some 7,000 years—tiger shark teeth that were used as blades......»»
