Missing sequence of the human Y chromosome may contain genes controlling stature and tumor development

Scientists have reported in the journal Genome Research that they have successfully cloned and characterized a previously intractable DNA sequence: a 554-kilobase-pair genomic segment near the centromere of the human Y chromosome. This sequence contains eight putatively active genes that could be implicated in sex-associated height differences and gonadal tumor development.

Discovery offers promise for treatment of age-related hearing loss

Researchers have discovered that deletion of a specific gene permits the proliferation of new hair cells in the cochlea of the inner ear -- a finding that offers promise for treatment of age-related hearing loss. This type of hearing loss is caused by aging, disease, certain drugs, and the cacophony of modern life. It is the most common cause of hearing loss in older people.

High levels of homocysteine, an amino acid in the blood, may indicate an increased risk of stroke

Observational studies measuring homocysteine concentrations in healthy individuals have found that, on average, those with high levels of homocysteine in their blood are more likely to have a stroke. But other factors that increase homocysteine concentration and stroke risk— such as smoking and socioeconomic class—may be responsible for the relationship observed in these studies, confounding the result.
