Scientists have long known that certain types of bacteria boost the immune system. Now, Loyola University Health System researchers have discovered how bacteria perform this essential task.
Senior author Katherine L. Knight, PhD. and colleagues report their discovery in a featured article in ... Read More
Researchers have discovered a new strain of bacteria that can produce non-toxic, comparatively inexpensive "rhamnolipids," and effectively help degrade polycyclic aromatic hydrocarbons, or PAHs -- environmental pollutants that are one of the most harmful aspects of oil spills.
Because of its ... Read More
A virus infection can incite the body to attack its own nerve tissue by activating rare, disease-fighting cells with receptors for both viral and nerve proteins. The dual-receptor observation suggests a way nerve damage might be triggered in susceptible young adults afflicted with multiple scler... Read More
Scientists at the University of Kent and University College Cork have manipulated simple bacteria into constructing internal compartments where biofuels and vaccines can be produced.
These micro-compartments eventually occupy almost 70 percent of the available space in a bacteria cell, enabli... Read More
A University of Iowa and University of Nebraska study has revealed the structure of an important HIV protein attached to the human protein that the virus hijacks during infection. The structural information might help researchers develop drugs that disrupt HIV replication. Image shows structure ... Read More
Four years ago at age 78, R., a retired professional known as much for her small-town Minnesotan resilience as her commitment to public service, developed a fleeting rash over her left chest. The rash, which turned out to be shingles, or herpes zoster, was hardly noticeable.
But the complica... Read More
U.S. regulators need to provide a clear path for drug companies to develop new antibiotics and should consider offering financial incentives, experts told a Congressional panel on Wednesday.
They said doctors are running out of effective antibiotics, yet inconsistent regulatory guidelines at ... Read More
Analysis of the protein structure of the 'motor' of motile bacteria at high resolution by Saori Maki-Yonekura and Koji Yonekura of the RIKEN SPring-8 Center, Harima, and Keiichi Namba of Osaka University has revealed the mechanism for transitioning between different movements.
The flagellum h... Read More
When infection with hepatitis C virus goes from acute to chronic, severe liver disease may occur which requires organ transplantation. Nearly 200 million people are chronically infected with HCV, necessitating approaches to preventing and treating infections. No HCV vaccine is available, and cur... Read More
Medical scientists in France have seen a recent rise in cases of meningitis C caused by a virulent substrain of bacteria whose emergence in other European countries led health authorities to introduce routine vaccination against the disease. Reporting this month online in The Journal of Infectio... Read More
The selenium clock is ticking for mountaintop mining companies, as the West Virginia Department of Environmental Protection prepares to crack down with water quality standards that producers have argued in the past are too expensive to meet.
But scientists at the West Virginia University Inst... Read More
Two Canadian researchers will be keeping a close eye on what hundreds of thousands of soccer fans take to the World Cup in South Africa _ and what they potentially bring home.
Dr. Kamran Khan, an infectious disease physician and scientist at St. Michael's Hospital in Toronto, and Dr. John Bro... Read More
Better understanding how the flu virus replicates and evolves to infect new hosts will help scientists find new ways to fight the flu. One option is the development of therapies that take advantage of the new findings by promoting mutagenesis -- treatments designed to generate increased mutation... Read More
Cancers of the neck and throat are much less likely to be fatal if they are caused by the human papilloma virus (HPV) rather than alcohol and smoking, researchers reported Monday. But if the tumor is caused by HPV and the patient also smokes, survival is significantly impaired, they found.
Th... Read More
Salmonellosis linked to Subway restaurants continues to plague the
state line with 2 cases now reported in Winnebago County. Those who
got sick ate at a Subway in Machesney Park. That now brings the total
to 60 cases of salmonellosis related to this outbreak in Illinois.
Normally thi... Read More
Synthetic biology hit the headlines when Craig Venter recently announced the creation of Synthia – the first organism with a computer as a parent.
JCVI-syn1.0, as the artificial microbe is officially known, will become a poster child for synthetic biology. But it was created from known geneti... Read More
This is spelunking with a twist. This is academic spelunking that is uncovering answers to questions. It is cave exploration that is helping sharpen the skills of tomorrow’s microbiologists.
Welcome to Todd Sandrin’s classroom. The associate director of the New College Division of Mathematica... Read More
While an out-of-control gusher deep in the Gulf of Mexico fouls beaches and chokes marshland habitat, another threat could be growing below the oil-slicked surface.
The nation’s worst oil spill could worsen and expand the oxygen-starved region of the Gulf labeled “the dead zone” for its inhos... Read More
Scientists are reporting the first evidence that a plastic antibody -- an artificial version of the proteins produced by the body's immune system to recognize and fight infections and foreign substances -- works in the bloodstream of a living animal. The discovery, they suggest in a report in th... Read More
President Obama has appointed a new Presidential Commission for the Study of Bioethical Issues, replacing his predecessor's President's Council on Bioethics. Like the previous entity and similar ones before it, the group will advise the president on a wide range of difficult, controversial scien... Read More
