In contrast, neither the receptor nor the necessary conditions exist for this anxiety-producing effect of the stress hormone before puberty, because the expression of the receptor is dependent upon hormonal tra...

Chlamydia vaccine a step closer to reality

...tics to treat Chlamydia, but there's no vaccine to prevent it. In many cases women don't know they are infected because there are not really any physical signs or symptoms, so by and large they don't get treatment."

Proponents of the technique, which was first tested nearly 20 years ago, regard it as more humane than the conventional methods of controlling wildlife populations, such as shooting, trappi...

New study sheds light on 'dark states' in DNA

...w that UV light can cause genetic alterations that prevent DNA from replicating properly, and these mutations can lead to diseases such as cancer. The faster a DNA molecule can dissipate UV energy, the lesser the chance that it will sustain damage -- so goes the conventional scientific wisdom. So the dark ...
