When it comes to the immune system, we're all more alike than previously thought, study finds

A recent study by scientists at the Fred Hutchinson Cancer Center found that any two people share tens of thousands of identical T-cell receptors, challenging previous dogma. This discovery has significant implications for diagnosing and treating autoimmune diseases and cancer, as it suggests a common immune response to disease.

Successful quitters can achieve abstinence despite periods of smoking before the end of treatment. Continued cessation treatments without interruption may increase 'real-world' quit rates for motivated smokers.

Lung cancer survival rates improved through use of individualized chemotherapy

A study published in Journal of Thoracic Oncology found that using the histoculture drug response assay to guide chemotherapy improves lung cancer survival and prognosis for patients who have undergone surgery. The use of adjuvant chemotherapy based on assay results showed a higher five-year survival rate compared to traditional treatm...

Finding variants in the human genome

The latest phase of the HapMap Project reveals rare genetic variants distributed unevenly among populations, with some genes under selection in different populations. The study provides a framework for future genetic studies of variation and disease, highlighting the importance of examining diverse populations.
