New Ways to Disarm Deadly South American Hemorrhagic Fever Viruses

New World hemorrhagic fevers are emerging infectious diseases found in South America that can cause terrible, Ebola-like symptoms. Current treatments are expensive and only partially effective.

Now, Howard Hughes Medical Institute (HHMI) researchers have discovered exactly how one type of New... Read More

Assessing Antibiotic Breakdown in Manure

Agricultural Research Service (ARS) scientist Scott Yates is studying how oxytetracycline (OTC), an antibiotic that is administered to animals, breaks down in cattle manure.

Livestock producers in the United States often use antibiotics to control disease in their animals, and confined U.S. l... Read More

Human cells exhibit foraging behavior like amoebae and bacteria

When cells move about in the body, they follow a complex pattern similar to that which amoebae and bacteria use when searching for food, a team of Vanderbilt researchers have found.

The discovery has a practical value for drug development: Incorporating this basic behavior into computer simul... Read More

Disease Cause Is Pinpointed With Genome

Two research teams have independently decoded the entire genome of patients to find the exact genetic cause of their diseases. The approach may offer a new start in the so far disappointing effort to identify the genetic roots of major killers like heart disease, diabetes and Alzheimer’s.

Sputnik, the first Virophage: I’m on the Radio, I’m on the Video

Once upon a time, in 2003, a French team discovered a giant virus infects amoeba. It was isolated from a cooling tower in the UK. They were so excited because it was so huge with a genome contains 900 protein-encoding genes (The words giant/ huge are totally hilarious. It’s not “Hulk”, it’s just... Read More

Like father Like son: He got his father’s virus!!

In an on-going study at the University of Rochester Medical Center, scientists have come across a new form of inheritance which would probably astonish Mendel himself. Research has shown that parents pass on the human herpes virus 6 “HHV-6″ to their offspring because the virus has integrated its... Read More

Viruses: Our new friends…

Nothing is impossible..

Things, you think are absolutely harmful, may be highly beneficial if we use them in a new way.

Viruses can be used in the treatment of cancer, a field known as oncolytic virotherapy.

But can you imagine that they are safer & highly specific than other traditiona... Read More

Pandemics in Retrospective

Now that we have experienced several months of the H1N1 pandemic, what have we learned about how it was handled? Watch Dr. Nicole Lurie (U.S. Department of Health and Human Services) and Dr. Kathryn Edwards (Vanderbilt University), discuss the public health responses to H1N1. Participants compar... Read More

Can We Detect Quantum Behavior in Viruses?

The weird world of quantum mechanics describes the strange, often contradictory, behaviour of small inanimate objects such as atoms. Researchers have now started looking for ways to detect quantum properties in more complex and larger entities, possibly even living organisms.

A German-Spanish... Read More

Audio interview with Martin Blaser--Losses in Ancestral Microbes Pose Health Risks to Humans

Selective losses of human-associated microorganisms may be responsible for a wide range of modern ailments, including esophageal diseases, obesity, asthma, and the epidemic spread of high-grade pathogens, according to Martin Blaser from New York University Langone Medical Center in New York City...

TB or Not TB?: Novel Detector Could Shorten Testing Times, Aid Treatment Efforts

Tuberculosis is a serious public health challenge in the developing world, where the infection claims roughly two million lives each year, according to the World Health Organization (WHO). Yet the disease, which is a leading killer of patients with HIV/AIDS, is cumbersome to detect, resulting i... Read More

Event - Ethical Issues in Synthetic Biology

June 24, 2009 12:30 – 1:30 PM

The emerging field of synthetic biology will allow researchers to create biological systems that do not occur naturally as well as to re-engineer existing biological systems to perform novel and beneficial tasks. As the science and its applications develop, a com... Read More

Infectious Virus Hidden in Chromosomes Can Be Passed from Parents to Children

Human herpesvirus 6 (HHV-6) infects nearly 100 percent of humans in early childhood, and the infection then lasts for the rest of a person's life. Now, a team led by Peter Medveczky, MD, a professor in the Department of Molecular Medicine at the University of South Florida (USF), has discovered ... Read More

Sensitive oscillators could lead to detection of harmful molecules, bacteria

By watching how energy moves across a tiny device akin to a springing diving board, Cornell researchers are a step closer to creating extraordinarily tiny sensors that can instantly recognize harmful substances in air or water.

The researchers, led by professor of applied and engineering phys... Read More

Trivalent influenza vaccine for the 2010-2011 season

The World Health Organization and the US Food & Drug Administration have decided on the composition of the influenza virus vaccine that will be used during the 2010-2011 season in the northern hemisphere. The trivalent preparation will contain the following influenza virus strains: A/California/... Read More

The Invention of PCR

Few technical breakthroughs have changed the face of their field like the Polymerase Chain Reaction (PCR). Gene cloning, sequencing of complex genomes, DNA fingerprinting and DNA-based diagnostics are just some of the techniques that were either inefficient, crude or plain impossible before PCR....

Mayo's Bad Rap - Is it Justified?

People often cite mayonnaise as a source for food poisoning, but studies have shown the condiment is not very conducive to bacterial growth. This is due to the ingredients used in commercially–prepared mayonnaise which typically include pasteurized eggs, salt and an acid like vinegar (acetic aci... Read More

Counting on Clicks to Finance the Battle Against AIDS, Malaria and Tuberculosis

To help average Americans do something to fight AIDS, tuberculosis and malaria, several foundations and travel companies, in cooperation with the United Nations, are starting a campaign to allow travelers to donate $2 every time they pay for a flight, a rental car or a hotel room.
