Synthetic proteins designed in the lab—using genetic sequences never before seen in nature—work much like the real thing to sustain life.
“What we have here are molecular machines that function quite well within a living organism even though they were designed from scratch and expressed from ... Read More
Proteins on the surface of a cell twist a viral protein into position, allowing the virus to start infection and cause Measles, all in a movement as graceful as a ballroom dance, say Mayo Clinic researchers.
A team led by Roberto Cattaneo, a Mayo molecular biologist, has described the crucial... Read More
The search for a universal flu vaccine has received a boost from a surprising source: the 2009 H1N1 pandemic flu strain. Using blood samples from patients infected with the 2009 H1N1 strain, researchers developed antibodies that could bind H1N1 viruses from the last decade, as well as the 1918 f... Read More
Tongue-piercers should pick their studs wisely -- even though the risk of oral infection is generally low, certain types of studs, particularly stainless steel, may collect more bacteria, researchers found.
Though none of the 85 young people in the study ever got periodontitis, bacterial load... Read More
Genetically modified microbes could perform many useful jobs, from making biofuels and drugs, to cleaning up toxic waste. But designing the complex biochemical pathways inside such microbes is a time-consuming process of trial and error.
Christopher Voigt, an associate professor at the Univer... Read More

Some additional info that I gathered on viruses on the verge of elimination (may or may not be new to you):
It appears that the next virus on the list of FAO to eradicate is PPR virus ( Read More
Malaysia has delayed a landmark field trial to release genetically modified mosquitoes designed to combat dengue fever, an official said Tuesday, following protests from environmentalists.
In the first experiment of its kind in Asia, 4,000-6,000 male Aedes aegypti mosquitoes were originally s... Read More
An experimental gel protected female monkeys from the AIDS virus in a test designed to mimic human sexual transmission, researchers said on Wednesday.
The gel uses an AIDS drug along with a zinc compound and protected all animals tested from infection with the monkey version of HIV, the resea... Read More
A team of researchers in Chile are working to come up with a vaccine against alcoholism. If successful, the patient will get a shot a month and not crave alcohol anymore.
The genetic therapy is based on aldehyde dehydrogenase, a group of enzymes that metabolize alcohol and are thus responsibl... Read More
Researchers have documented yet another health benefit for circumcision, which can protect men against the AIDS virus, saying it can protect their wives and girlfriends from a virus that causes cervical cancer.
Wives and girlfriends of circumcised men had a 28 percent lower rate of infection ... Read More
As the UK and a number of European countries are now experiencing epidemics of influenza, including A(H1N1) which was the 2009 pandemic virus, the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) warns that the consequences of non-vaccination could emerge as a new flu e...

Researchers at Cairns in far north Queensland are launching a biological assault on dengue fever with the release of thousands of specially-bred mosquitoes.
The world-first field trial is being staged in Cairns and aims to wipe out dengue fever.
Thousands of mosquitos bred in a laboratory ... Read More
In a breakthrough that’s sure to stir up some controversy, Princeton researchers have reported that they have for the first time created artificial proteins from scratch in the lab that have enabled the growth of living cells. To achieve this, they created genetic sequences never seen in nature ... Read More
Dr. Emil Kozarov and a team of researchers at the Columbia University College of Dental Medicine have identified specific bacteria that may have a key role in vascular pathogenesis, specifically atherosclerosis, or what is commonly referred to as "hardening of the arteries" - the number one caus...

To date, the notion of inoculating people against drug use is a symbolic one – the idea being that anything from positive peer pressure to self esteem can render people resistant to the lure of drugs.
But such inoculation may soon become a much more literal concept: By combining a cocaine ana... Read More
A new study finds that people with high levels of methicillin-resistant staphylococcus aureus (MRSA) bacteria in the nose are more likely to have other areas of the body colonized by MRSA, which can cause potentially fatal infections.
Researchers at Rhode Island Hospital wanted to assess the ... Read More
By rethinking what happens on the surface of things, engineers at Harvard University have discovered that Bacillus subtilis biofilm colonies exhibit an unmatched ability to repel a wide range of liquids -- and even vapors.
Centimeters across yet only hundreds of microns thick, such slimy bact... Read More
For the first time, researchers have developed a 3-D picture of a herpes virus protein interacting with a key part of the human cellular machinery, enhancing our understanding of how it hijacks human cells to spread infection and opening up new possibilities for stepping in to prevent or treat i...

Derek Smith, Professor of Infectious Disease Informatics, University of Cambridge, U.K., has developed a method for visualizing antigenic evolution by creating two-dimensional maps in a process called antigenic cartography. These maps are made with data that provide information on the antigen... Read More
