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.....»»
First mass measurement with rare-RI ring reveals fine structure of element abundance patterns
Scientists have demonstrated the effectiveness of an innovative nuclear mass measurement method using the rare-RI ring (R3) facility at the Radioactive Isotope Beam Factory, and applied it to the mass measurement of a neutron-rich palladium isotope......»»

A team of researchers affiliated with a large number of institutions in the U.S. has attempted to determine the vulnerability of bird populations to alternative energy production. In their paper published in the journal Royal Society Open Science, th.....»»
It"s the pore that counts: Spatial distribution of pores helps determine where carbon is stored in the soil
Soils store more carbon than all the vegetation on the Earth's surface. However, there are still many unanswered questions about precisely which processes favor accumulation in the soil. Under the leadership of the Helmholtz Centre for Environmental.....»»
How blending Inuit knowledge and Western science can help improve polar bear health
Nanuk, the Inuktitut word for polar bear, is an iconic animal, capturing public imaginations and starring in international marketing campaigns. As nanuk has increasingly been used as the poster species for climate change, it has also become separated.....»»
DIY digital archaeology: New methods for visualizing small objects and artifacts
The ability to visually represent artifacts, whether inorganics like stone, ceramic and metal, or organics such as bone and plant material, has always been of great importance to the field of anthropology and archaeology. For researchers, educators,.....»»

Herbivore identity and density interact to determine plant-mediated interactions between herbivores
Plants are often exposed to multiple herbivores, and densities of these attackers often fluctuate greatly in the field. Herbivore identity and density are known to be two major drivers of plant-mediated interactions among herbivores, but their combin.....»»
Global team of scientists determine "fingerprint" for how much heat, drought is too much for forests
How hot is too hot, and how dry is too dry, for the Earth's forests? A new study from an international team of researchers found the answers—by looking at decades of dying trees......»»
US Justice Department is investigating two antitrust issues concerning Google Maps
According to anonymous sources, the US Department of Justice Department is investigating Google to determine if its Maps app breaks any antitrust laws. Insiders familiar with the situation told Reuters that the DoJ looked at two potential issues......»»
‘RealityScan’ is a new app from Epic Games that uses the iPhone camera to create 3D models
Epic Games announced on Monday a new app called “RealityScan,” which will let anyone use the iPhone camera to scan objects and turn them into high-fidelity 3D models. The app was developed using technologies from Capturing Reality, a company spe.....»»
US returns smuggled ancient artifacts to Libya
The United States on Thursday returned a cache of smuggled ancient artifacts to Libya as the oil-rich Mediterranean country struggles to protect its heritage against the backdrop of years of war, turmoil and unrest......»»
Direct cosmogenic nuclide dating of Olduvai lithic industry
Toshiyuki Fujioka and Alfonso Benito-Calvo, researchers at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), have recently published a paper in the Journal of Human Evolution with the results of burial dating using the cosmog.....»»
Senators Question School Surveillance Startups on Data, Civil Rights
School surveillance companies are not doing enough to determine whether their products unfairly target minority groups, according to a report released by U.S. Senators Elizabeth Warren and Ed Markey. From a report: Democratic senators sent questions.....»»
Rover ready: Next steps for ExoMars
ESA's ExoMars rover is confirmed technically ready for launch, and a fast-track study is under way to determine options for bringing the mission to Mars......»»
Ancient helium leaking from core offers clues of Earth"s formation
Helium-3, a rare isotope of helium gas, is leaking out of Earth's core, a new study reports. Because almost all helium-3 is from the Big Bang, the gas leak adds evidence that Earth formed inside a solar nebula, which has long been debated......»»
The face of a medieval wanderer: Isotopic investigation of remains in Scotland
Isotope analysis of the "bodies in the bog" found at Cramond reveals several crossed a politically divided Scotland, meeting their end hundreds of miles from their place of birth......»»
Reevaluation puts mid-Proterozoic oxygen levels higher than previously reported
Oxygen levels in the atmosphere during the mid-Proterozoic—about 1.4 billion years ago—were higher than previously thought, according to an international team of researchers who looked at oxygen combined with sulfur to determine that previous num.....»»
Hundreds of gene regulatory motifs cooperate and conflict to make brain cells
DNA is considered the blueprint of our human bodies. It codes for the tens of thousands of genes that determine whether a cell transforms into a brain cell, heart cell or even cancer cell. Other DNA sequences, known as enhancers, determine if genes a.....»»
This is why boa constrictors can still breathe while squeezing the life out of prey
