Over the past twenty years, neuroscientists have discovered that brain maturation continues through an individual’s midtwenties. The United States Supreme Court cited this research to support its abolition of the juvenile death penalty in Roper v. Simmons. Now the Court is faced with two cases that challenge the constitutionality of sentencing juveniles to life imprisonment without parole. Many...

This exploratory analysis examines the role of the Internet in juvenile prostitution cases coming to the attention of law enforcement. The National Juvenile Prostitution Study (N-JPS) collected information from a national sample of law enforcement agencies about the characteristics of juvenile prostitution cases. In comparison to non-Internet juvenile prostitution cases, Internet juvenile prost...

In male golden hamsters (Mesocricetus auratus), attack frequency decreases during puberty. As serotonin inhibits offensive responses in adult hamsters, it is hypothesized that the serotonin system becomes upregulated in the hypothalamus during puberty. This hypothesis was tested through acute treatment with fluoxetine, a serotonin reuptake inhibitor, as well as through analysis of serotonin inn...

Sexual abuse by juveniles is widely recognized as a significant problem. As communities have become more aware of juvenile sex offending they have responded with increasingly severe responses. This is despite recidivism data suggesting that a relatively small group of juveniles commit repeat sexual offenses after there has been an official response to their sexual offending. Research has shown ...

Previously, it was concluded that the nervous systems of juvenile snails were not capable of mediating long-term memory (LTM). However, exposure and training of those juvenile snails in the presence of a predator cue significantly altered their ability to learn and form LTM. In addition, there are some strains of Lymnaea which have been identified as 'smart'. These snails form LTM significantly...

In this study, random sampling conducted and 90 individuals of Persian sturgeon having 3-5g weight, collected by trawling in 3 earthen ponds and 15 individuals having 10-20g weight, collected by small net in 3 fiberglass Vans. After recording of biometrical characteristics, the intestine and rearing water were cultured on TSA medium. Gram staining and complementary tests were conducted. In orde...

Female individuals of dioecious plants invest their resources more in storage and defence, the males have higher nitrogen content invested production pollen grains. An unresolved problem is whether this strategy occurs only sexually mature or can also occur juvenile plants. To answer this, Taxus baccata (L.) needles from rooted cuttings (juveniles) a pot experiment were compared for carbon, nit...

Juveniles, like adults, should be afforded the right to raise an insanity defense. In this commentary on the article by Morse and Bonnie on the abolition of the insanity defense, we explain why so few juveniles across the United States are granted access to the insanity defense and the reasons that they should have that option. We also consider whether the Delling case was the best suited vehic...

The effects of root diffusates of selected plants within the families Chenopodiaceae and Cruciferae and the hatching agent zinc chloride were tested for their effects on hatching and emergence of juveniles from cysts of Heterodera schachtii and a race of H. trifolii parasitic on Chenopodaceae and Cruciferae in The Netherlands. Although all diffusates strongly stimulated hatching of juveniles of...

Consistent individual differences within (animal personality) and across (behavioural syndrome) behaviours became well recognized during the past decade. Nevertheless, our knowledge about the evolutionary and developmental mechanisms behind the phenomena is still incomplete. Here, we explored if risk-taking and exploration were consistent and linked to different ecologically relevant traits in ...
