Week in review: An Ebola update

A week is a long time in science. With Ebola, the U.S. government admits new patient; joint pains stall a major clinical trial; U.S. grants immunity to vaccine developers; and new doubts are raised about Ebola dying quickly outside the human body.

Virus killing dolphins along East Coast reaches Fla. Keys

New understanding into how MERS infects

A new study has shown how the deadly MERS virus enters human cells. This new insight provides information about the rate of infection. The results could also signal a new path for treatment.

HIV infection is based on viral-cell targets

Although the human immunodeficiency virus (HIV) inserts itself at different locations in a human cell, researchers have found that specific integration sites determine the speed that the infection spreads at.

First Ebola treatment trials to start in west Africa

Although cervical cancer screening saves lives, about eight million women ages 21 to 65 years have not been screened for cervical cancer in the past five years. This is according to a study from Centers for Disease Control and Prevention (CDC).

Understanding mosquito feeding, to avoid disease spread

Biologists have discovered that mosquitoes bite male birds twice as often as they bite females. The same is true with people: mosquitoes bite men more often than women. Knowing this could help to stop the insects from spreading viruses to people.

Lack of access to Ebola frustrates scientists

Leading scientists have said that attempts to develop drug treatments for Ebola are being frustrated by restrictions imposed on access to the virus.

Apple iPhones, Mac computers targets of harmful malware threat

Apple products including iPhones and popular Mac personal computers are being targeted perhaps by the most serious malware threat to those devices yet.

This electron micrograph depicts the vesiculovirus responsible for vesicular stomatitis (VS) in horses, cattle and pigs. As a member of the Rhabdoviridae family of viruses, you’ll note the morphologic similarity, i.e., bullet-shaped virion, between this vesicular stomatitis virus (VSV), and the rabies virus.
