Zoonoses: Diseases Passed From Animals To Humans
Zoonoses are diseases passed from animals to humans. The most recent high-profile example is swine flu. There are several dozen such diseases that affect humans. The Centers For Disease Control says:
Abstract
Microbiologic infections acquired from animals, known as zoonoses, pose a risk to public health. An estimated 60% of emerging human pathogens are zoonotic. [...]
Disinfectants: Bacteria Adapt
Dr. Gerard Fleming is the lead researcher on a new study of the growth of antibiotic-resistant bacteria. Dr. Fleming works from the National University of Ireland in Galway in the department of microbiology.
The research suggests that some bacteria eat disinfectants. The study looked at Pseudomonas aeruginosa which is responsible for infections in people [...]

- What are seismograms? How do you read them?Seismograms are the records (paper copy) produced by seismographs used to calculate the location and magnitude of an earthquake. They show how the ground moves with the passage of time. On a seismogram, the HORIZONTAL axis = time (measured in seconds) and the VERTICAL axis= ground displacement (usually measured in millimeters). When there is NO EQ reading th […]

- Climate Change Implicated in Decline of Horseshoe CrabsLEETOWN, W. Va. — A distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age, according to a study that used genomics to assess historical trends in population sizes. The new research also indicates that horseshoe crabs numbers may continue to decline in the future because of predi […]
