New Way Deadly Food-borne Bacteria Is Spread

University of Central Florida Microbiology Professor Keith Ireton has uncovered a previously unknown mechanism that plays an important role in the spread of a deadly food-borne bacterium.

Listeria monocytogenes is a bacterium that can cause pregnant women to lose their fetuses and trigger fat... Read More

New chemically-activated antigen could expedite development of HIV vaccine

Scientists working to develop a vaccine for the human immunodeficiency virus (HIV) report they have created the first antigen that induces protective antibodies capable of blocking infection of human cells by genetically-diverse strains of HIV. The new antigen differs from previously-tested vacc... Read More

So when McCutcheon, a molecular biologist at the University of Arizona, heard the zzsssstttt of cic... Read More

New discovery reveals fate of nanoparticles in human cells

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have uncovered what happens to biomimetic nanoparticles when they enter human cells. They found that the important proteins that make up the outer layer of these nanoparticles are degraded by an enzyme called... Read More

Fish Fend Off Invading Germs With An Initial Response Similar To One Found In Humans

Since the human response to infection is highly complex, research to understand how people fight infection is facilitated by studying how similar processes occur in simpler organisms. Zebrafish are becoming an important model for human disease, since they are easily handled, maintained and manip... Read More

What should we make of the HIV vaccine 'triumph'?

Almost 26 years after HIV was discovered to be the cause of AIDS, a vaccine has at last shown signs of protecting people. Results of the RV144 trial on 16,000 volunteers in Thailand show that those receiving the vaccine reduced their risk of HIV infection by about a third – the first evidence th... Read More

That Fish Smell

From an advice column in the San Diego Reader:

"Hey, Matt: Why does all seafood smell the same, even though it comes from such different kinds of animals (mollusks, arthropods, vertebrates)? Okay, so maybe it doesn’t all smell exactly the same, but similar. The only thing all those creatures ... Read More

Stem cell hope for childhood motor neuron disease

A form of motor neuron disease that affects children has been treated in mice with injections of stem cells into the spinal cord. The treatment extended the lives of the mice beyond and kept them more mobile, giving hope that similar approaches might help people.

The treated mice were bred to... Read More

A world first: Vaccine helps prevent HIV infection

For the first time, an experimental vaccine has prevented infection with the AIDS virus, a watershed event in the deadly epidemic and a surprising result. Recent failures led many scientists to think such a vaccine might never be possible.

The vaccine cut the risk of becoming infected with HI... Read More

Fungus Enhances Susceptibility Of Resistant Malaria Mosquito To Pesticides

In areas where malaria mosquitoes have become resistant to chemical pesticides, mosquito-killing fungi can be an effective tool. Fungal spores can effectively infect and kill malaria mosquitoes, even those that are resistant to pesticides. Moreover, the mosquitoes become more susceptible to the ... Read More

New nanotechnology material kills antibiotic-resitant bacteria

Doctors are not well armed in the fight against antibiotic-resitant bacteria. It is very difficult – or, in the worst case, impossible – to fight such infections. A team of researchers in Münster has now developed a unique nanotechnology material that kills antibiotic-resitant bacteria.
