Micrococcus bacteria thrive on the open-air lattice of synthetic fibers--where they sit chomping on the fatty acids in our sweat, turning them into shorter, stinkier molecules. Christopher Intagliata reports.

Until relatively recently, the fungus Malassezia was thought to have one favorite home: us. As the dominant fungus on human skin and sometimes-cause of dandruff, the yeast Malassezia was thought to live a simple if sometimes irritating domestic existence humbly mooching off the oils we exude.

A study led by St. Jude Children’s Research Hospital scientists found the avian influenza A H3N8 virus that killed harbor seals along the New England coast can spread through respiratory droplets and poses a threat to humans. The research appears in the current issue of the scientific journal Na... Read More
The ability of pathogenic bacteria to evolve resistance to antibiotic drugs poses a growing threat to human health worldwide. And scientists have now discovered that some of our microscopic enemies may be even craftier than we suspected, using hidden genetic changes to promote rapid evolution un... Read More
The virus family Filoviridae is home to Ebola virus, as well as several other viruses that can cause severe hemorrhagic fever in humans and other primates. Ebola virus is in the news because of the outbreak in Guinea that has spread to several neighboring African countries. The fatality rate of ... Read More

Wolbachia are maternally transmitted endosymbionts that often alter their arthropod hosts’ biology to favor the success of infected females, and they may also serve as a speciation microbe driving reproductive isolation. Two of these host manipulations include killing males outrigh... Read More
A team of scientists has reconstructed how bacteria tightly control their growth and division, the cell cycle, by destroying specific proteins through regulated protein degradation. All organisms use controlled protein degradation to alter cell behavior in response to changing environment. A pro... Read More
Recently identified cell-cycle controls are targets for new drugs that fight infections by shutting down division.
A cell is not a soap bubble that can simply pinch in two to reproduce. The ability to faithfully copy genetic material and distribute it equally to daughter cells is fundamental ... Read More
Animal genomes are known to contain captured retroviruses, typically referred to as endogenous retroviruses (ERVs). Many of these elements are still transcribed and are known to be involved in both beneficial functions in animal biology, such as placenta formation, and not-so beneficial functio... Read More
Twenty-six species of Cryptosporidium have been recognised and 18 species declared non-valid in a recent shake-up of the parasite's taxonomy using DNA sequencing techniques.
Cryptosporidium is the second biggest cause of infant diarrhoea and death in developing countries, and is found across ... Read More
Whether it’s the Black Death of 1350 or the Ebola virus in West Africa, one thing deadly pandemics have in common is that their progress takes a geographical course. But researcher Lars Skog at KTH Royal Institute of Technology is one of those developing geoinformation systems that can help heal... Read More
A novel mode of defense against bacteria, such as the causal agent of tuberculosis or Staphylococcus aureus, has been identified in humans by studying a small, aquatic flatworm, the planarian. This discovery highlights the importance of studying alternative model organisms, and opens the way tow... Read More
Many pathogens are transmitted by insect bites. The abundance of vectors (as the transmitting insects are called) depends on seasonal and other environmental fluctuations. A new article demonstrates that Plasmodium parasites react to mosquitoes biting their hosts, and that the parasite responses... Read More
During the winter of 1962 in California, a new virus was isolated from the oropharynx of 4 children who had been hospitalized with respiratory disease that included pneumonia and bronchiolitis. On the basis of its physical, chemical, and biological properties, the virus was classified as an ente... Read More
I have the grating feeling that the subject of self-assembly of complex biological structures may not always amass the level of respect it deserves. I reckon that its importance is generally appreciated but, as topics go, it tends at times to be set aside. Yet, this is one of the most magnificen... Read More
