New stable isotope map of Angola helps archaeologists trace individual life histories across the African Diaspora
Archaeologists at UC Santa Cruz used predictive modeling to map strontium isotope ratios across all of modern-day Angola, a region in Southwest Africa that was once a major hub for the transatlantic slave trade. Researchers compared the resulting map.....»»
New research is helping scientists better understand how microstructures change
The orientations of these infinitesimally small separations between individual "grains" of a polycrystalline material have big effects. In a material such as aluminum, these collections of grains (called microstructures) determine properties such as.....»»
Geochemical analyses of stone artifacts reveal long-distance voyaging among Pacific Islands during the last millennium
Polynesian peoples are renowned for their advanced sailing technology and for reaching the most remote islands on the planet centuries before the Europeans reached the Americas. Through swift eastward migrations that are now well covered by archaeolo.....»»
Sex and the single gene: New research shows a genetic "master switch" determines sex in most animals
In humans and other animals, sex is usually determined by a single gene. However, there are claims that in some species, such as platyfish, it takes a whole "parliament" of genes acting together to determine whether offspring develop as a male or fem.....»»
New compact accelerator to help preserve heritage artworks
Beyond fundamental research, accelerators are well known for their contribution to the medical field, especially to cancer therapy. However, they can also be used in more unexpected ways, such as for the analysis of historical artifacts and works of.....»»
Researchers streamline production of purified actinium-225 isotope, for potential cancer treatments
Thanks to a recent upgrade to the medical isotope facilities at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, actinium-225 (Ac-225), an isotope that shows great promise for treating cancer, can now be produced, purified, and s.....»»
X-file cracked: Mini-key determines DNA shape
We finally know why our DNA has an X shape. This finding by researchers at the Netherlands Cancer Institute may have much broader implications for how our cells behave. "It looks like we have uncovered a universal mechanism by which cells determine t.....»»
Samsung soliciting Chinese GPU talent; Exynos 2400 will determine the victor
