Evolution is so important for biology, medicine and a genera... Read More
The yeast S.pombe is one of the best-studied microbes in the world. First isolated from East African millet beer over a century ago, it's been used as a model organism in molecular and cell biology for the past sixty years. And yet scientists have now just uncovered what may be its most striking... Read More
There is no approved medicine to treat polyomaviruses, which afflict people with weakened immune systems, but scientists have found that a chemical compound called Retro-2 is able to reduce significantly the infectivity and spread of the viruses in lab cell cultures. Now they are working to impr... Read More
In its early days, ca. 1945-1965, molecular biology was a particularly collegial undertaking, characterized by free sharing of research data and a relative lack of egotistical behavior. The reason for this marvel may well have been that there was so much to discover—so many low hanging fruits—th... Read More
The study found that many models provided only cursory reference to the uncertainties of the information and data, or the parameters used
Research by scientists at the University of Liverpool has found that greater consideration of the limitations and uncertainties in infectious disease model... Read More
The delightful word 'oocyan' refers to the trait of blue-green eggshell color that occurs in native chickens of Chile (Mapuche fowl) and some of their descendants in North America and Europe, as well as certain Asian chicken breeds (e.g. Dongxiang, Lushi).

As the year closes out, we enter into the giving seasons of a variety of traditions. Lurking among the more pleasant types of giving is the 2013 – 2014 flu season, a viral gift that often keeps on giving. To combat this, reminders about the potential dangers of influenza and the importance of va... Read More
Delivering healthy bacteria in a pill could help patients harboring out-of-balance microbial communities. Yogurt eaters already know that not all bacteria are bad for you. They may not realize that some bacteria are so important that one day people may fight off disease with pills filled with ba... Read More
Bacteria grow faster if they feed each other. The division of labour is more efficient than a struggle through life without help from others – this is also true for microorganisms. Researchers from Research Group Experimental Ecology and Evolution at the Max Planck Institute for Chemical Ecology... Read More
Slothful response from regulators and manufacturers means antibiotic resistance is missed. Bacteria that are resistant to almost all antibiotics are dreaded by physicians and patients alike. Finding such microbes in a hospital is bad enough, but failing to detect them can lead to something much ... Read More
years of fighting the deadly and incurable virus, scientists think they may be able to find a way to really kill it. On Monday, the White House and the National Institutes of Health announced a new, $100 million effort to try to find a cure.
In the latest study, researchers tested a modified ... Read More
