Gene therapy

Researchers have found new ways to interfere with a co-receptor important to HIV infection, and the outcomes so far are encouraging

Artificial retinas that allow the blind to see

In this chapter from his new e-book, journalist Carl Zimmer tries to reconcile the visions of techno-immortalists with the exigencies imposed by real-world biology

Recent findings suggest novel paths to treatment

Researchers pin down two genes that may be responsible for abnormal neural development in Down's mice embryos. The findings may help identify possible therapeutic strategies to treat cognitive defects in human patients

After years of false starts, a new generation of DNA vaccines and medicines for HIV, influenza and other stubborn illnesses is now in clinical trials

As researchers learn more about genetic profile of various cancers, other work is charging ahead to deliver personalized vaccines targeted to a patient's own tumor cells

A new generation of oncolytic viruses are entering late-stage clinical trials, repurposing smallpox and herpesvirus to take on tough tumors

Drugs that are specific to hepatitis C will soon go from trial to clinic, giving more patients hope, but a vaccine is still elusive

A treatment that appears safe and effective in treating natural color-blindness in monkeys might just lead to colorizing the world for similarly afflicted people, along with restoring sight to those with other retinal diseases

Lessons learned by James M. Wilson, the scientist behind the first gene therapy death

Three subjects with a rare form of visual impairment found their sight still better a year after gene therapy, and their immune systems seemed happy with the treatment, too
