TB bacteria's trash-eating inspires search for new drugs
(Phys.org) —When hijacking a garbage truck, one might as well make use of the trash. That logic drives how tuberculosis-causing bacteria feed, say Cornell scientists.

How do immune cells manage to sort through vast numbers of similar-looking proteins within the body to detect foreign invaders and fight infections? McGill researchers used computational tools to examine what kind of solutions ...
Humans have been raising cows for their meat, hides and milk for millennia. Now it appears that the cow immune system also has something to offer. A new study led by scientists from The Scripps Research Institute ...
A simple method has been found that tells people who have become seriously ill after a tick bite once and for all whether they have bacteria in their blood.
Evolutionarily speaking, we humans are doing pretty well. Over the last few million years, we've developed big brains, social structures and more recently, culture, cities, philosophy, airplanes and the Internet. ...
(Phys.org) —Gaining control of the ability of mature tissues to generate stem cells is the central medical challenge of our day. From taming cancer, to providing compatible cell banks for replacement organs, ...
Scientists at The Scripps Research Institute (TSRI) have devised a powerful new technique for finding antibodies that have a desired biological effect. Antibodies, which can bind to billions of distinct targets, ...
When studying any kind of population—people or cells—averaging is a useful, if flawed, form of measurement. According to the US Census Bureau, the average American household size in 2010 was 2.59. Of ...
When infections occur in the body, stem cells in the blood often jump into action by multiplying and differentiating into mature immune cells that can fight off illness. But repeated infections and inflammation ...
Parasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies' blood cells, a finding that offers new insight into how pathogens break through a host's defenses.
Researchers at Stanford University School of Medicine have developed a new technique to see how different types of cells interact in a living mouse. The process uses light-emitting proteins that glow when two types of cells ...
Even bacteria have a kind of "immune system" they use to defend themselves against unwanted intruders – in their case, viruses. Scientists at the Helmholtz Center for Infection Research (HZI) in Braunschweig, ...
(Phys.org) —Malignant catarrhal fever (MCF) is a disease that is almost always fatal in cattle. Cows contract MCF after coming into contact with wildebeest carrying a form of herpes virus known as alcelaphine ...
Simply getting anything into space is tough, but doing so against a strict deadline can be really stressful. Researchers in an ESA laboratory nervously checked the clock as they extracted immune cells – ...
Coating medical supplies with an antimicrobial material is one approach that bioengineers are using to combat the increasing spread of multidrug-resistant bacteria. Multidrug-resistant Staphylococcus aureus ...
