The presence of male sperm and seminal fluid causes female worms to shrivel and die after giving birth, Princeton University researchers reported this week in the journal Science. The demise of the female appears to benefit the male worm by removing her from the mating pool for other males.

Not so long ago, most people thought that the only good microbe was a dead microbe.
But then scientists started to realize that even though some bugs can make us sick and even kill us, most don't.
In fact, in the past decade attitudes about the bacteria, fungi, viruses and other microbes l... Read More
Bacteria can evolve rapidly to adapt to environmental change. When the "environment" is the immune response of an infected host, this evolution can turn harmless bacteria into life-threatening pathogens. A study published on December 12 in PLOS Pathogens provides insight into how this happens.

A new way to attack flu viruses is taking shape in laboratories at Rutgers University, where scientists have identified chemical agents that block the virus’s ability to replicate itself in cell culture.
These novel compounds show promise for a new class of antiviral medicines to fight much-f... Read More
North Carolina could be looking at a record year for flu deaths, or at the very least a near record year. North Carolina health officials released new flu numbers Friday, saying seven more people have died in the last week. That brings the total number of deaths from flu-related complications th...

Plop living, swimming bacteria into a novel water-based, nontoxic liquid crystal and a new physics takes over. The dynamic interaction of the bacteria with the liquid crystal creates a novel form of soft matter: living liquid crystal.
The new type of active material, which holds promise for i... Read More

A form of malaria common in India, Southeast Asia and South America attacks human red blood cells by clamping down on the cells with a pair of proteins, new research at Washington University School of Medicine in St. Louis has revealed.
The study provides details that will help scientists des... Read More
To know how many proteins assemble together at the nanoscale is fundamental for understanding protein function. Sometimes, proteins must be in an "oligomeric" state to be functional, although "oligomerization" of certain proteins can also lead to diseases. The ability to determine protein stoich... Read More
By tinkering with their chemical structures, researchers at the University of California, San Diego School of Medicine have essentially re-invented a class of popular antimicrobial drugs, restoring and in some cases, expanding or improving, their effectiveness against drug-resistant pathogens in...

Saudi Arabia has so far recorded no cases of the deadly MERS coronavirus among pilgrims in the holy city of Mecca for the annual haj season, the Ministry of Health said on Saturday.
The death toll from the respiratory virus in the kingdom, where the strain emerged last year, has reached 51, a... Read More
It's a mould breaker. Researchers have discovered the first fungus that behaves like a farmer.
We already know that soil fungi can help bacteria travel quickly from A to B. The fungal filaments provide favourable conditions for the bacteria, and so act as "highways" through the soil. But thes... 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
Researchers have tested a preliminary form of a vaccine against the disease, which is spread by the bite of the mosquito and kills more than 600,000 people each year. Until now, developing malaria vaccines has been challenging. A vaccine must incorporate key proteins from the malaria parasites, ... Read More

Circumcision drastically alters the microbiome of the penis, changes that could explain why circumcision offers protection against HIV and other viral infections. In a study to be published on April 16 in mBio®, the online open-access journal of the American Society for Microbiology, researchers... Read More
