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.....»»
Mercedes-Benz addresses Level 3 legalities; lawyers say uncertainty lingers
Mercedes-Benz says "well-established legal systems" should determine whether the company is liable for crashes and other incidents that may arise from use of its Drive Pilot system. Whether human drivers bear some liability remains a key legal questi.....»»
Clever fly offers lessons on advanced predator adaptations
The saffron robber fly (Laphria saffrana) is an extremely fast bee-colored hunter that has to determine, while perched, which insects it wants to chase and eat. This is complicated by the fact that its eyes have poor resolution, especially at distanc.....»»
Host genetics shown to play a significant role in the composition of switchgrass root microbiomes
Plants provide a home for a wide diversity of microbes, especially in their roots. In turn, these communities can provide important benefits for the host. A study published in Current Biology investigated how the genetics of host plants determine the.....»»
The best Indiana Jones villains, ranked
Indiana Jones, the swashbuckling archaeologist, most often contend with some monstrous villains to obtain the artifacts he seeks. Let's rank these bad guys!.....»»
Training AI to recognize fly mating identifies a gene that controls mating positions
A research group at the Graduate School of Science, Nagoya University in Japan has used artificial intelligence to determine that piezo, a channel that receives mechanical stimuli, plays a role in controlling the mating posture of male fruit flies (D.....»»
Researchers determine chloroplast size unlikely option for improving photosynthetic efficiency
A group of RIPE researchers have found, for the first time, that chloroplast size manipulations are unlikely to be an option for increasing crop photosynthetic efficiency. Their work was recently published in New Phytologist......»»
Artifacts on Australian continental shelf show Flying Foam Passage must be treated as protected archaeological site
The new discovery of ancient stone artifacts at an underwater spring off the Western Australia Pilbara coast has confirmed the location is a submerged archaeological site where more ancient Aboriginal artifacts are likely hidden beneath the sea......»»
New finding suggests how and why temperatures determine the sex of turtles
Warmer temperatures are known to make more turtle eggs become female hatchlings, but new research out of Duke University shows that those females also have a higher capacity for egg production, even before their sex is set......»»
When plants feed on fungi: Novel method enables unrestricted isotope analyses
Most plants worldwide live in symbiosis with fungi. Often there is an exchange of nutrients from which both partners benefit. In numerous other cases, however, the plants feed unilaterally at the expense of the fungi......»»
Molecular filament shielded our young solar system from supernova, suggests study
Isotope ratios found in meteorites suggest that a supernova exploded nearby while the sun and solar system were still forming. But the blast wave from a supernova that close could have potentially destroyed the nascent solar system. New calculations.....»»
Researcher discovers new type of atomic nucleus
An experiment performed in the Accelerator Laboratory of University of Jyväskylä, Finland, has succeeded in producing a previously unknown atomic nucleus, 190-Astatine, consisting of 85 protons and 105 neutrons. The nucleus is the lightest isotope.....»»
Plant life found to determine soil bacteria diversity in the Arctic tundra
Living and nonliving factors that influence the types of vegetation that grow at different elevations in the Arctic tundra also regulate the types of bacteria that grow in the soil. The distribution of generalist bacteria, which can adapt to a broade.....»»
Scientists discover critical factors that determine the survival of airborne viruses
Critical insights into why airborne viruses lose their infectivity have been uncovered by scientists at the University of Bristol. The findings, published in the Journal of the Royal Society Interface today, reveal how cleaner air kills the virus sig.....»»
Scientists develop inorganic resins for generating and purifying radium and actinium
Targeted alpha therapy can destroy cancerous cells without harming healthy cells. It's especially useful for treating metastasized cancers. The Department of Energy (DOE) Office of Science's Isotope Program is developing and marketing novel radioacti.....»»
Digital artifacts boost internationalization of platform businesses, finds study
A new study from the University of Eastern Finland and the University of Vaasa sheds light on how digital-based start-ups, and especially platform businesses, can make use of digital artifacts in their international endeavors and business development.....»»
The spirit of Juneteenth: The freedom to self-determine
To be able to self-determine is to be able to control one's own life and tell one's own story—an ability that people who were enslaved in the U.S. did not legally have before the Emancipation Proclamation (1862) or the 13th and 14th amendments. The.....»»
How to turn safe mode on and off on your Android phone
When you have an issue with your phone, safe mode disables all third-party apps to determine if they are to blame. Here's how to turn safe mode on and off......»»
Study investigates how young fish ingest plastic
In a new study, marine biologist Carolin Müller of the Leibniz Centre for Tropical Marine Research (ZMT) demonstrates the ingestion of microplastic particles by juvenile sea bream. She also investigated which environmental factors determine whether.....»»
Climate change: Challenges of capturing sufficient carbon through large-scale seaweed farming
The potential of global seaweed farming to help capture sufficient carbon may not be feasible given the large ocean areas needed to remove between 2.5 and 13 gigatons of atmospheric carbon per year to meet climate goals, according to a study publishe.....»»
NASA"s Curiosity captures Martian morning, afternoon in new "postcard"
After completing a major software update in April, NASA's Curiosity Mars rover took a last look at "Marker Band Valley" before leaving it behind, capturing a "postcard" of the scene......»»
