Proteome atlas for the tuberculosis pathogen
Researchers from ETH Zurich have mapped the coordinates for all the proteins of the tuberculosis pathogen Mycobacterium tuberculosis. Thanks to this "atlas", scientists are now able to easily find and accurately measure every ...
Ubiquitous engineered nanomaterials cause lung inflammation, study finds
A consortium of scientists from across the country has found that breathing ultrafine particles from a large family of materials that increasingly are found in a host of household and commercial products, from sunscreens ...
Physical by smartphone becoming real possibility
It's not a "Star Trek" tricorder, but by hooking a variety of gadgets onto a smartphone you could almost get a complete physical - without the paper gown or even a visit to the doctor's office.
The first caffeine-'addicted' bacteria
Some people may joke about living on caffeine, but scientists now have genetically engineered E. coli bacteria to do that—literally. Their report in the journal ACS Synthetic Biology describes bacteria bein ...
Flipping the 'off' switch on cell growth
A protein known for turning on genes to help cells survive low-oxygen conditions also slows down the copying of new DNA strands, thus shutting down the growth of new cells, Johns Hopkins researchers report. Their discovery ...
Watson's medical expertise offered commercially
The Watson supercomputer is graduating from its medical residency and is being offered commercially to doctors and health insurance companies, IBM said Friday.
CT scans help answer question of how fish lungs evolved
(Phys.org)—One of the great problems of evolution is to understand how the major features of organisms have changed over great swaths of time. How did limbs evolve from fins? How did bird feathers arise ...
Brazil to inventory Amazon rainforest trees
Brazil will undertake the massive task of cataloging the trees of the Amazon, in an effort to better monitor and protect the world's largest tropical forest, the environment ministry announced Friday.
Study shows potential of differentiated iPS cells in cell therapy without immune rejection
A new study from Boston University School of Medicine (BUSM) shows that tissues derived from induced pluripotent stem (iPS) cells in an experimental model were not rejected when transplanted back into genetically identical ...
Residents near Chinese e-waste site face greater cancer risk
Residents living near an e-waste recycling site in China face elevated risks of lung cancer, according to a recent study co-authored by Oregon State University researchers.
Breath test identifies bacteria's fingerprint
(Phys.org)—Scientists have identified the chemical 'fingerprints' given off by specific bacteria when present in the lungs, potentially allowing for a quick and simple breath test to diagnose infections such as tuberculosis.
Research shows isoprene from biofuel plants likely to lead to ozone deaths
Chemical probe finds fungal organism function: Activity-based protein profiling suggests how fungus becomes pathogenic
(Phys.org)—Two unique chemical probes designed at Pacific Northwest National Laboratory are helping scientists find how a pathogenic organism responsible for a severe lung infection thrives in human serum. ...
