Basis for DNA ejection from single phage particles

...acting the membrane. Phage nucleic acid transport poses a fascinating biophysical problem: Transport is unidirectional and linear; it concerns a unique molecule the size of which may represent 50 times that of the bacterium. The driving force for DNA transport is still poorly defined. It was hypothesized ...

New lab technique identifies high levels of pathogens in therapy pool

...ulder, said the high presence of aerosol pathogens poses the greatest concern for very young children, the elderly and people whose immune systems are compromised. The pool attendants probably became ill because they were exposed to high levels of the pathogens by working consecutive, full days in the indo...

Stopping smallpox in its tracks: A new anti-viral approach

Natural or deliberate exposure to smallpox poses a great health threat, especially since routine smallpox vaccinations have been discontinued and no clinically approved treatment currently exists. In the February 1 issue of the Journal of Clinical Investigation, Ellis Reinherz and colleagues from H...

Protein offers way to stop microscopic parasites in their tracks

...b studies Toxoplasma both because of the threat it poses to patients and for the potential insights it can offer into other apicomplexan parasites, which include malaria and Cryptosporidium. Malaria, which is spread by mosquito bites, kills at least 1 million people per year through damage to red blood cel...

South America's vast pantanal wetland may become next everglades, UNU experts warn

...ther land uses." "Moreover, global climate change poses great environmental threats to wetlands," according to the analysis, "fundamentally altering their ecology, biodiversity and species composition." The global threat to the Pantanal: Climate change The UNU analysis says a warming of 3° to 4°C could ...

Scientists rid stem cell culture of key animal cells

...of animal pathogens tainting human stem cell lines poses a problem for the safe clinical use of many, if not all, of the current cell lines now in use. Until now, scientists have had to grow and sustain stem cells through the tedious daily task of generating mouse feeder cells from mouse embryos. Feeder c...

Ecological destruction fuels emerging diseases

...'s parasites, and the prospect of cataloguing them poses a daunting technical challenge. Since the physical characteristics of many parasites are very similar, Dr. Brooks and his colleagues are using the latest molecular taxonomy tools to classify parasites based on genetic characteristics. "These things ...
