Promiscuous females are trying to avoid selfish genes
So-called 'selfish genes' may make females more promiscuous and also lower male fertility.
Low density of Earth's core due to oxygen and silicon impurities
During accretion and differentiation of the Earth, chemical interactions in a silicate magma ocean and liquid iron drove silicon and oxygen impurities into what went on to become the liquid outer core. Contrasting ...
Link between shape of crocodile's lower jaw and diet examined
(Phys.org)—Researchers have shown how the shape of a crocodile's snout could determine its ability to feast on certain types of prey, from large mammals to small fish.
Phase-change material with unexpected optical-reflectivity properties offers fresh perspectives for data storage
Memory is a central component of any computer or mobile device. Digital memories must not only store large amounts of data in a small space—and in a way that it is conveniently written, read and erased—but ...
Oxygen to the core
(Phys.org)—An international collaboration including researchers from Lawrence Livermore National Laboratory has discovered that the Earth's core formed under more oxidizing condition's than previously proposed.
Adele, Swift soar as US digital music sales sing
