Overhead, the Bayway is now four-landed. Shows first campus
roads including round-about. Cobb, Seibert and Miller are visible.
Area that is now Palm Hammock has been filled with dredged sand.
The area east of the white line will all be filled in. This was the
creation of new habitat very much like the natural action of
beaches where new sand builds up. What will become of this
naked white sand?

Chapel, Sheen and CMLS are good landmarks.
Area that is now Palm Hammock is between road to Lewis house
and Marina Bay lake. The “island of habitat” is now 60 years old.
What has taken place? Has a diversity of plants accumulated?

Outbreak of NIH
'superbug' provides
valuable lessons

(TIME.com) -- Reports of "superbugs" that can evade our strongest antibiotic treatments are becoming
uncomfortably commonplace (think MRSA), but that's no reason to become complacent about the growing
threat from invisible armies of microbes.
We got a reminder of that during one such outbreak of the latest microbial villain, carbapenem-resistant
Klebsiella pneumoniae, or CRKP, that occurred at one of the nation's premier hospitals, the Clinical Center of
the National Institutes on Health, last year.
Although the incident is a year old, researchers just reported on a state-of-the-art genetic fingerprinting
analysis of the gut bacterium to reveal that despite the best containment efforts, the wily microbe managed to
break free of protective barriers meant to keep it in check and spread to 17 patients, killing six (five others
died of other conditions, but their health was likely worsened by infection with CRKP).
Your pediatrician always said “finish the medicine, why?”
Fitness and its measurement
• Darwinian
Fitness
Poor fitness (no children)
Modertate fitness (some children
likely to have children of their own)
High fitness (lots of
children likely to have
children of their own)
– Individuals with a certain phenotype leave more
surviving offspring in the next generation than
individuals with an alternative phenotype
– A relative concept; the most fit phenotype is simply the
one that produces, on average, the greatest number of
offspring that survive and reproduce in the next
generation. Survival alone is not enough.
