In the search for alternatives to conventional antibiotics, researchers have identified an enzyme that kills the bacteria that causes strep throat.
The enzyme, PlyC, operates by locking onto the surface of a bacteria cell and chewing a hole in the cell wall large enough for the bacteria’s inn... Read More
What types of microbes do mothers transmit to their newborns and how universal is maternal microbial transmission throughout animals, including from your mother?
The sterile womb paradigm is an enduring premise in biology that human infants are born sterile. Recent studies suggest that infant... Read More
Researchers at the University of Illinois at Urbana-Champaign have developed a versatile iPhone-based biosensor that, with about $200 worth of parts, is just as accurate as a $50,000 laboratory spectrophotometer.
The system, consisting of an iPhone cradle and an app, can detect viruses, bacte... Read More
In the mid-1990s, people in the United States and Canada began to notice something grotesque. The frogs in their local ponds were sprouting extra legs.
As news of the deformed frogs spread, the Minnesota state government set up a hot line for sightings, and soon they got hundreds of calls fro... Read More
Imagine if you could take living cells, load them into a printer, and squirt out a 3D tissue that could develop into a kidney or a heart. Scientists are one step closer to that reality, now that they have developed the first printer for embryonic human stem cells.
In a new study, researchers ... Read More
Researchers from computer firm IBM say they have invented a new non-toxic gel that can kill deadly drug-resistant bacteria by cutting through the sludge that shelters them and attacking the germ's cell membrane.
If verified, the finding could herald a breakthrough in the fight against the sup... Read More
The mosquitoes that spread dengue fever tap into the domestic networks of humans, along with their bloodstreams, finds a study recently published in the Proceedings of the National Academy of Sciences (PNAS).
Like the housefly, the Aedes aegypti mosquito that spreads the dengue vir... Read More
Scientists have identified the chemical 'fingerprints' given off by specific bacteria when present in the lungs, potentially allowing for a quick and simple breath test to diagnose infections such as tuberculosis.
Publishing their study today in the Journal of Breath Research, the researchers... Read More
More than half of ground turkey samples are contaminated with fecal bacteria, according to a new study from Consumer Reports. In addition, the magazine found that more than 90 percent of the ground turkey samples it tested contained at least one of the five bacteria the test was looking for -- s... Read More
A potentially pathogenic fungus has found a home living in extreme conditions in some of the most common household appliances, researchers have found. A new paper published in the British Mycological Society journal, Fungal Biology, published by Elsevier, shows that these sites make perfect habi... Read More
Placement of copper objects in intensive care unit (ICU) hospital rooms reduced the number of healthcare-acquired infections (HAIs) in patients by more than half, according to a new study published in the May issue of Infection Control and Hospital Epidemiology, in a special topic issue focused ...

Being born by cesarean section has been tied to higher risks for various health problems in children, and now a new study finds these babies also have fewer "good" bacteria in their digestive tract.
Similarly, babies who were exclusively or even partially formula-fed rather than breast-fed al... Read More
A few days ago, the Food and Drug Administration released two important documents related to antibiotic use in livestock raising, and what the results of that antibiotic use are. I’d say that they released them quietly, except, when it comes to this issue, every release seems to be quiet, never ... Read More
Vibrio cholerae, the scourge of nations lacking clean water. Pseudomonas aeruginosa, the microbe that plagues people with cystic fibrosis. Acinetobacter species, opportunistic organisms that can infect vulnerable people. Escherichia coli, a culprit in food-borne illnesses.
When these bacteria... Read More
For the first time we are close to creating artificial life from scratch. So says Craig Venter, founder of the J. Craig Venter Institute in Rockville, Maryland, and famed for creating the first cell with a synthetic genome.
"We think we're close, but we've not submitted a paper yet," he said ... Read More
