Prolonged brain development of marmosets could serve as model for human evolution
The development of primate brains is shaped by various inputs. However, these inputs differ between independent breeders, such as great apes, and cooperative breeders, such as the common marmoset (Callithrix jacchus) and humans. In these species, gro.....»»
Observations explore the properties of giant spiral galaxy UGC 2885
Astronomers have employed the Canada-France-Hawaii Telescope (CFHT) to perform comprehensive multiwavelength observations of a large and massive spiral galaxy known as UGC 2885. Results of the observational campaign, published October 21 on the pre-p.....»»
Investigating the flow of fluids with non-monotonic, "S-shaped" rheology
Water and oil, and some other simple fluids, respond in the same way to all levels of shear stress. These are termed Newtonian fluids, and their viscosity is constant for all stresses although it will vary with temperature. Under different stresses a.....»»

Metal peroxide (MO2, M=Ca, Sr, Ba) is an alternative to hydrogen peroxide (H2O2). It has excellent oxidative properties, superior chemical stability, high purity, and is easy to store and transport. It has been widely used in wastewater treatment and.....»»
Synthesis method improves catalytic activity by controlling the surface structure of metal particles
Fine-tuning the reactions that produce hydrogen (H2) for use as a clean fuel is an important endeavor to fight against climate change. Researchers at Tohoku University and the Tokyo University of Science have succeeded in improving the catalytic acti.....»»
Is "U-shaped happiness" universal? Not for rural subsistence populations, say researchers
A theory that's been around for more than a decade describes a person's subjective well-being—"happiness"—as having a U-shape throughout the course of one's life. If plotted on a graph, the shape would be concave, revealing high happiness levels.....»»
Astronomers take a close look at a dandelion-shaped supernova and zombie star
In 1181, a new star shone near the Cassiopeia constellation for six months before disappearing. This event, recorded as a "guest star" by Chinese and Japanese observers almost a millennium ago, has puzzled astronomers for centuries. It is one of a fe.....»»
