‘David and Goliath’ viruses shed light on the origin of jumping...

University of British Columbia researchers have identified a small virus that attacks another virus more than 100 times its own size, rescuing the infected zooplankton from certain death. The discovery provides clues to the evolutionary origin of som...

New findings on drug tolerance in TB suggest ideas for shorter...

New findings on how tuberculosis (TB) bacteria develop multi-drug tolerance point to ways TB infections might be cured more quickly. The study will be published April 1 in the journal Cell. The results identify both a mechanism and a potenti...

Cancer-causing virus exploits key cell-survival proteins

COLUMBUS, Ohio -- A cancer-causing retrovirus exploits key proteins in its host cells to extend the life of those cells, thereby prolonging its own survival and ability to spread, according to a new study by researchers at The Ohio State University...

Research shows how pathogenic bacteria hide inside host cells

A new study into Staphylococcus aureus, the bacterium which is responsible for severe chronic infections worldwide, reveals how bacteria have developed a strategy of hiding within host cells to escape the immune system as well as many antibacterial ...

New research aims to shut down viral assembly line

Under the electron microscope, a coronavirus may resemble a spiny sea urchin or appear crownlike, (the shape from which this family of pathogens takes its name). Previously recognized as the second leading cause of the common cold in humans a...

Protein helps parasite survive in host cells

Researchers at Washington University School of Medicine in St. Louis have learned why changes in a single gene, ROP18, contribute substantially to dangerous forms of the parasite Toxoplasma gondii. The answer has likely moved science a step cl...

Blame the environment: Why vaccines may be ineffective for some people

A new discovery may explain why a tuberculosis vaccine is not as effective for some people as anticipated, and potentially explains why other vaccines do not work as well for some as they do for others. In a research report presented in the December...

Reading the signs: Plants and animals found common ground in response...

Though it's been at least a billion years since plants and animals shared a common ancestor, they have through the eons shared a common threat in the form of microbes, including bacteria, eukaryotes and viruses. This has resulted in remarkably sim...

A new player in the innate immunity game?

Scientists have demonstrated for the first time that a certain class of RNA (known as long non-protein-coding RNA [lncRNA]) are involved in the host response to viral infection. These findings, published today in the online journal mBio®, could gr...

Scientists reveal the sex wars of the truffle grounds

They are one of the most highly prized delicacies in the culinary world, but now scientists have discovered that black truffles are locked in a gender war for reproduction. The research, published in New Phytologist as the truffle season begins, rep...
