Most bacteria divide quite precisely and their daughter cells are often the same size. The reason for this accuracy is not really known, but it must be important because it is such a frequent phenomenon. This requires good measuring sticks, systems that calculate distance from the ends and restr... Read More
Most people try to avoid catching the flu by taking precautions such as washing their hands often, avoiding people who are already sick, or getting a flu shot.
However, scientist are giving volunteers the flu on purpose by squirting the virus up their nose, all in the name of science.
Why woul... Read More
Despite major efforts to keep operating rooms sterile, surgical wound infections remain a serious and stubborn problem, killing up to 8,200 patients a year in the U.S. A study by Columbia University Medical Center (CUMC) researchers suggests that narrow-spectrum ultraviolet (UV) light could dram...

The lab was a crime scene; dead and dying cells were everywhere—but did they commit mass suicide or were they murdered? The burly young post doc who discovered the corpses sat in the corner sobbing softly, his PI by his side. She was trying in vain to comfort her most promising young scientist i... Read More
A new test for HPV has been cleared as way to screen for cervical cancer, but doctors are concerned that it doesn't do enough to protect younger women.
By its name alone, the Pap smear sounds like an uncomfortable procedure. Say it aloud: Pap smear. And it’s not too pretty to experience eithe... Read More
Two health care workers went to the emergency room with flu-like symptoms after coming into contact with a patient confirmed to have Middle East Respiratory Syndrome, or MERS, officials said Tuesday.
The Florida patient represents the second confirmed case of MERS brought into the United Stat... Read More
Scientists have long believed that microorganisms that produce methane swim toward the hydrogen gas they need to stay alive, but it has been too hard to prove in the lab.
Montana State University researchers have now overcome those challenges, allowing them to verify it for the first time, sa... Read More
Researchers are using new nanoscale imaging approaches to shed light on the dynamic activities of rotaviruses, important pathogens that cause life-threatening diarrhea in young children. Once a rotavirus enters a host cell, it sheds its outermost protein layer, leaving behind a double-layered pa... Read More
You probably remember foot and mouth disease (FMD) from the 2001 outbreak in the UK that prompted the culling of over 10 million sheep and cattle, but the disease affects livestock all over the world. It's a particular problem in Africa, where wildlife that harbor the picornavirus that causes FM... Read More
People living near pig farms or agricultural fields fertilized with pig manure are more likely to become infected with methicillin-resistant Staphylococcus aureus (MRSA) bacteria, according to a paper published today in JAMA Internal Medicine1.
Previous research has found that livestock worke... Read More
By tracing the evolutionary origin of a drug-like protein ring found in sunflowers, Australian and US scientists have discovered a diverse, 18-million-year-old group of buried proteins in daisy seeds.
Researchers at The University of Western Australia, working with academics from The Universi... Read More
A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors....

Mathematicians have found that by varying the timing of treatments, doctors may be able to increase the odds that a disease outbreak will die off suddenly.
Herding cats is a cakewalk compared with getting people to take flu vaccine shots in the last weeks of summer—work, school, limited pharm... Read More
Study contradicts notion that microbes consumed most of the gas after 2010 Deepwater Horizon spill.
When the blowout of the Deepwater Horizon oil well sent some 400,000 tonnes of methane into the Gulf of Mexico in April 2010, many scientists and others feared it would linger. So researchers w... Read More
By evaluating the bacteria and fungi found in fossilized feces, microbiologists are providing evidence to help support archeologists' hypotheses regarding cultures living in the Caribbean over 1,500 years ago. Researchers discuss how the analysis of 1,500-year-old coprolites from archeologica... Read More
Natural selection favours those with a greater capacity to generate genetic variation.
Some gamblers succeed by spiriting cards up their sleeves, giving them a wider range of hands to play. So do some bacteria, whose great capacity for genetic variability helps them evolve and adapt to rapidl... Read More
When it comes to infecting humans and animals, bacteria need a helping hand.
Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven individual loops on the ... Read More

The centuries-long search for the fountain of youth has yielded only a few promising leads, one of which entails an extreme, emaciating diet. A new study of the tiny nematode worm C. elegans begins to explain this marvel of calorie restriction and hints at an easier way to achieve longevity.

As a virologist who has worked on poliovirus since 1979, I would be remiss if I did not note that today, 24 October, is World Polio Day. World Polio Day was established by Rotary International over a decade ago to commemorate the birth of Jonas Salk, who led the first team to develop a vaccine a... Read More
