Watching HIV Bud from Cells

May 19, 2014 2:15 pm | Videos | Comments

University of Utah researchers devised a way to watch newly forming AIDS virus particles emerging or “budding” from infected human cells without interfering with the process. The method shows a protein named ALIX gets involved during the final stages of virus replication, not earlier, as was believed previously.

"Bystander" Chronic Infections Thwart Development of Immune Cell Memory

May 16, 2014 1:15 pm | News | Comments

Studies of vaccine programs in the developing world have revealed that individuals with chronic infections tend to be less likely to develop the fullest possible immunity benefits from vaccines for unrelated illnesses. The underlying mechanisms for that impairment, however, are unclear.


Blood Seeking Mosquitoes

May 15, 2014 12:41 pm | by Skip Derra | Articles | Comments

Insights into controlling mosquitoes often focuses on how they are attracted to humans, which is by smelling the carbon dioxide we exhale. But once they get close to us, mosquitos often steer toward exposed areas of skin such as ankles and feet. New research has shown that an often overlooked mosquito organ, the maxillary palp, plays an important role in mosquito targeting.

Malaria Severity Not Determined Solely by Parasite Levels in Blood

May 8, 2014 1:17 pm | News | Comments

Although malaria kills some 600,000 African children each year, most cases of the mosquito-borne parasitic disease in children are mild. Repeated infection does generate some immunity, and episodes of severe malaria are unusual once a child reaches age 5. However, the relative contributions of such factors as the level of malaria-causing parasites in a person’s blood to disease severity and to development of immunity aren't well understood.


New Study Sheds Light on Survivors of the Black Death

May 8, 2014 11:55 am | News | Comments

A new study suggests that people who survived the medieval mass-killing plague known as the Black Death lived significantly longer and were healthier than people who lived before the epidemic struck in 1347. The study by anthropologist Sharon DeWitte in the College of Arts and Sciences provides the first look at how the plague, called bubonic plague today, shaped population demographics and health for generations.

Starting Signal for Antiviral Defense

May 7, 2014 1:21 pm | News | Comments

Cells have to protect themselves against damage in their genetic material for one thing, but also against attack from the outside, by viruses for example. They do this by using different mechanisms: special proteins search out and detect defects in the cell's own DNA, while the immune system takes action against intruders. Scientists have now shown that the two protective mechanisms are linked by a shared protein.

MERS Experts Working on Way to Block Virus

May 6, 2014 12:45 pm | News | Comments

Undersea Warfare: Viruses Hijack Deep-sea Bacteria at Hydrothermal Vents

May 2, 2014 1:10 pm | News | Comments

More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war. Like pirates boarding a treasure-laden ship, the viruses infect bacterial cells to get the loot: tiny globules of elemental sulfur stored inside the bacterial cells.

Newly Arrived Virus Gains Foothold in Caribbean

May 1, 2014 6:17 pm | by David Mcfadden - Associated Press - Associated Press | News | Comments

A recently arrived mosquito-borne virus that causes an abrupt onset of high fever and intense joint pain is rapidly gaining a foothold in many spots of the Caribbean, health experts said. There are currently more than 4,000 confirmed cases of the fast-spreading chikungunya virus in the Caribbean, most of them in the French Caribbean islands of Martinique, Guadeloupe and St. Martin.

Scientists Urge Delay in Destroying Last Smallpox

May 1, 2014 5:22 pm | by Lauran Neergaard - AP Medical Writer - Associated Press | News | Comments

More than three decades after the eradication of smallpox, U.S. officials say it's still not time to destroy the last known stockpiles of the virus behind one of history's deadliest diseases. The world's health ministers meet later this month to debate, again, the fate of vials held under tight security in two labs — one in the U.S. and one in Russia.

Promising Agents Burst Through ‘Superbug’ Defenses to Fight Antibiotic Resistance
