New book explores the hidden world of viruses

"Carl Zimmer is one of the best science writers we have today. A Planet of Viruses is an important primer on the viruses living within and around all of us-sometimes funny, other times shocking, and always accessible. Whether discussing the common cold and flu, little-known viruses that attack bacteria or protect oceans, or the world's viral future as seen through our encounters with HIV or SARS, Zimmer's writing is lively, knowledgeable, and graced with poetic touches."-Rebecca Skloot, author of The Immortal Life of Henrietta Lacks.

Study offers means of activating T cells to fight disease without antigenic triggers

For much of the time our T cells-the white blood cells that act as the police of the immune system-are in what immunologists call a "quiescent state," a sort of standby mode. For years, scientists have wondered if quiescence occurred by default or whether T cells need to work at remaining silent.

Inhalation therapy might halt and reverse progression of pulmonary arterial hypertension

Patients with pulmonary arterial hypertension struggle with severe symptoms, which include shortness of breath, exhaustion and a lack of vitality. Moreover, the disease, which is more common in women, often claims the patient's life within a few years of its development.
