In 1859 an Australian farmer named Thomas Austin released 24 grey rabbits from Europe into the wild because it “could do little harm and might provide a touch of home, in addition to a spot of hunting.”
By the end of the century, the rabbits had begun to overrun native ecosystems, reaching ... Read More
A group of Israeli researchers has succeeded in isolating a protein that kills bacteria, in what is a first step toward developing a substitute for antibiotics. The substance isolated by a Tel Aviv University team prevents bacteria from dividing, thus destroying them and combatting infections. “... Read More
A virus that invaded the genomes of humanity's ancestors millions of years ago now plays a critical role in the embryonic stem cells from which all cells in the human body derive, new research shows.
The discovery sheds light on the role viruses play in human evolution and could help scientis... Read More
There’s a hidden war going on for your fruit. The apple snatchers and orange thieves aren’t what you might think, though. Humans and other fruit-loving species are locked in an ongoing evolutionary battle against the microbes that also want to feast. Now, researchers believe they have found out ... Read More
University of British Columbia researchers have developed a vaccine that may halt the spread of West Nile Virus (WNV) among common and endangered bird species.
WNV, a mosquito borne pathogen, arrived in North America in 1999 and is now endemic across the continent. In 2012 alone, WNV killed 2... Read More
Six new cases of Heartland virus disease have been identified in residents of Missouri and Tennessee. The cause of this disease appears to be a member of the Phlebovirus genus in the Bunyaviridae family that was first identified in 2009 and appears to be transmitted by the Lone Star tick (Amblyo...

The prevalence of dangerous strains of the human papillomavirus — the most common sexually transmitted infection in the United States and a principal cause of cervical cancer — has dropped by half among teenage girls in recent years, a striking measure of success for a vaccine against the virus ...

One would assume offhand that the pathways for synthesis and assembly of the major constituents of a bacterial cell “talk to each other,” i. e. they are tightly interwoven processes. Tampering with the biosynthesis of one should affect all the others, right? Wouldn’t you expect, for instance, th... Read More
Endangered Amur tigers (also called Siberian tigers) face challenges from poaching, decimation of their prey base, and habitat fragmentation, but a disease from domestic dogs may be the straw that broke the tiger's back, according to the authors of a study in mBio this week. A team of scientists... Read More
A protein in Salmonella inactivates mast cells -- critical players in the body’s fight against bacteria and other pathogens -- rendering them unable to protect against bacterial spread in the body, according to researchers at Duke Medicine and Duke-National University of Singapore (Duke-NUS).

University of Michigan microbiologist Pat Schloss, Ph.D., describes latest findings from Human Microbiome Project. Based on their findings in today’s Nature, there is no single healthy microbiome. Rather each person harbors a unique and varied collection of bacteria that’s the result of life his... Read More
