But microbes are only part of the story — the effect also depends on a healthy diet. Gut bacteria from lean mice can invade the guts of obesity-prone cage-mates and help their new hosts to fight weight gain.
Researchers led by Jeffrey Gordon, a biologist at Washington University in St. Louis... Read More
On 3 April 2013, the China Health and Family Planning Commission notified WHO of an additional four cases of human infection with influenza A(H7N9). The four patients are from Jiangsu province in eastern China. There is no link between the cases.
The patients include a 45-year-old woman with ... Read More
Bacteria have evolved resistance to every known class of antibiotic, creating an urgent need for methods to identify new antibiotics that work by different mechanisms. We have developed a new approach to antibiotic discovery that provides a short cut for identifying antibacterial molecules and ... Read More
Scientists have discovered a “microbial Pompeii” preserved on the teeth of skeletons around 1,000 years old.
The key to the discovery is the dental calculus, or “plaque,” which preserves bacteria and microscopic particles of food on the surfaces of teeth, effectively creating a mineral tomb f... Read More
When astronauts launch into space, a microbial entourage follows. And the sheer number of these followers would give celebrities on Twitter a run for their money. The estimate is that normal, healthy adults have ten times as many microbial cells as human cells within their bodies; countless more... Read More
Depending upon whom you ask, the smell that has plagued La Jolla Cove has been “putrid,” “noxious” or “like the East River used to smell,” for quite a while. Nose-pinching is commonplace.
But now, the stench of bird guano emanating from the cliffs in the seaside neighborhood has become, off... Read More
Doses of a human gut microbe helped to reverse behavioral problems in mice with autism-like symptoms, researchers report today in Cell. The treatment also reduced gastrointestinal problems in the animals that were similar to those that often accompany autism in humans.
The work builds on prev... Read More
Many experts believe that chronic fatigue syndrome (CFS) has several root causes including some viruses. Now, lead scientists Shara Pantry, Maria Medveczky and Peter Medveczky of the University of South Florida’s Morsani College of Medicine, along with the help of several collaborating scientist...

A newly discovered fungus that feasts on the skin of amphibians is threatening to decimate a species of salamander in the Netherlands, according to new research.
Fire salamanders are one of the most recognizable salamander species in Europe, and are characterized by their distinct yellow- and... Read More
In their paper in mBio this week, Wang et al present FrameBot, a program that combines frameshift correction and nearest-neighbor identification in one Java-based tool. Read More
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...

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
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.

Immune system defenses against dangerous bacteria in the gut can be breached by turning off a single molecular switch that governs production of the protective mucus lining our intestinal walls, according to a study led by researchers at Yale, the University of British Columbia, and the Weizmann...

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.

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
