"The WHO, largely unchanged since its creation, is ill-equipped to deal with the disease threats that this new world creates...the recent Ebola outbreak is a case in point. Even the WHO's director-general, Margaret Chan, said her organisation was "overwhelmed" and admitted that a crisis on that ... Read More
Although much of the country has barely noticed, avian influenza — a version of the virus that generated “Killer Bird Flu!” headlines a decade ago — is now sweeping the Midwest. Read More
Researchers at Harvard T. H. Chan School of Public Health and the Broad Institute have identified a protein on the surface of human red blood cells that serves as an essential entry point for invasion by the malaria parasite. The presence of this protein, called CD55, was found to be critical to... Read More
CHICAGO--May 1, 2015-- Lymphatic pump treatment (LPT) shows promise in managing pneumonia when combined with antibiotic treatment, according to a new study published in The Journal of the American Osteopathic Association. Read More
A vaccine containing a protein necessary for virus replication can boost an HIV-infected patient's immune system, according to clinical research published in the open access journal Retrovirology. This boost can result in increased effectiveness of antiretroviral drugs. Read More
Ebola is on the decline in Guinea, one of three West African hit hard by the epidemic. The country's teeming capital of 2 million, Conakry, had only a single known case last week. As part of the endgame, hundreds of local workers have gone house to house in the remaining Ebola pockets in recent ... Read More
Is the end of HIV near? Findings published this week in Antimicrobial Agents and Chemotherapy report that a novel, subdermal implant delivering potent antiretroviral (ARV) drugs shows extreme promise in stopping the spread of HIV. Read More
This picture was taken in early October 2014 in the Washington, DC metro area. The temperature that week had been in the mid-70's during the day to the low 60's at night (Fahrenheit), and it hadn't been too humid. This had grown at the base of a tree, and was very large -- my hand is in there fo... Read More
Bacteria that feed on methane can control its concentration once it is released from the ocean floor. This can potentially stop the greenhouse gas from entering the atmosphere. But ocean currents can easily disturb dinner, according to new study in Nature Geoscience.
There is a large, and rel... Read More
University at Buffalo researchers have discovered a way to easily and effectively fasten proteins to nanoparticles by simply mixing them together. The biotechnology model is described in the journal Nature Chemistry. Read More
Virus populations do not consist of a single member with a defined nucleic acid sequence, but are dynamic distributions of nonidentical but related members called a quasispecies (illustrated at left). While next-generation sequencing methods have the capability of describing a quasispecies, the ... Read More

The well-known judgment of the Constitutional Court December 2, 2010, (Background, No. 7, p. A), tells us that the education to which everyone is entitled and whose guarantee is for the government as their own task is not contracted for Therefore, a proc... Read More
I am a big believer that different pedagogical approaches can "reach" different students. In most of my classes, I give students an optional assignment: come up with a creative project that explores some aspect of class. This takes several steps. First, I make the students come up with an ide... Read More

Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich demonstrate for the first time that bacteriophages (bacterial viruses) carry genetic instructions for proteins that mediate the transport of their DNA to specialized replication sites in the host cell. Read More

A major goal of viral oncotherapy – the use of viruses to destroy tumors – is to design viruses that kill tumor cells but not normal cells. Two adenoviruses provide perfect examples of how this specificity can be achieved.
Adenovirus CG0070, designed to treat bladder cancer, and adenovirus O... Read More
About eight percent of human DNA is viral: it consists of retroviral genomes produced by infections that occurred many years ago. These endogenous retroviruses are passed from parent to child in our DNA. Some of these viral genomes are activated for a brief time during human embryogenesis, sugge... Read More
