Peer-to-peer file sharing over the Internet is a popular alternative approach for people worldwide to get the digital content they want.

Active aging is much more than exercise

Posted: 08 Oct 2014 09:19 AM PDT

The global population is aging rapidly, and the growing numbers of elderly challenge our societal structures, not least the health sector, which is why authorities encourage the elderly to lead active and healthy life styles.

Combined behavioral support, medication offers smokers best chance of quitting

Numerous randomized clinical trials have shown the effectiveness of the two major forms of smoking cessation treatment -- behavioral support and medication -- in helping smokers quit. Researchers have now demonstrated that this approach can successfully translate to the "real world" and that a combination of the two treatments offers almost a threefold chance of success over attempts to quit without using a cessation aid.

Molecule that protects women's eggs identified

Posted: 07 Oct 2014 06:22 AM PDT

In order to be able to have a child, a woman needs eggs that can grow and mature. After fertilization, an embryo forms. During the maturation process, the egg goes through a number of stages of reductional division, called meiosis. If problems occur during any of these stages, the woman can become infertile. Researchers now discovered that the molecule Greatwall kinase is of great importance in order for the eggs of the female mouse to be able to complete the first phase and move on to the second meiotic division during the maturation of the egg.
