Sociality may allow organisms to colonize habitats where similar species with solitary lifestyles cannot persist. We test this idea by taking advantage of the distribution of Anelosimus spiders in Ecuador, where highly social species are common in the lowland rainforest, while related 'subsocial' species (with both social and solitary life cycle phases) are present only at higher elevations.

Studying living things can prove to be highly significant when evaluating contamination suffered by a specific environment. A research team from the University of the Basque Country (UPV/EHU), with Dr. Nestor Etxebarria as director, is involved in this monitoring of contaminants. As Dr. Etxebarria explains, "it is known that ports are contaminated; what we are investigating is to what extent the contaminants...

UC Irvine researchers have identified the brain mechanism that switches off traumatic feelings associated with bad memories, a finding that could lead to the development of drugs to treat panic disorders. Scientists from UCI and the University of Muenster in Germany found that a small brain protein called neuropeptide S is involved in erasing traumatic responses to adverse memories by working on a...

Adiponectin, a protein produced by fat cells, may play a pivotal and counterintuitive role in cardiovascular health for older Americans according to a new study accepted for publication in the Journal of Clinical Endocrinology & Metabolism (JCEM). As people lose weight, the concentration level of adiponectin in the bloodstream increases. In previous studies, high adiponectin concentration has been...

The aim of this study is to prepare sphene coating on titanium alloy (Ti-6Al-4V) for orthopaedic applications using the plasma spray method. The results indicated that sphene coating was obtained with a uniform and dense microstructure. Plasma-sprayed sphene coating possessed a significantly improved bonding strength and chemical stability compared with that plasma-sprayed hydroxyapatite (HAp) coating....

While scientists and physicians know what happens if you don't get six to eight hours of shut-eye a night, investigators have long been puzzled about what controls the actual need for sleep. Researchers at the University of Pennsylvania School of Medicine might have an answer, at least in fruit flies. In a recent study of fruit flies, they identified a gene that controls sleep.
