Ask for help if needed!
Use the catch up binder to get caught up
quickly after being away.

BIOLOGY IS EVERYWHERE…
 July 2006
 Cyclist Floyd Landis tested
positive for synthetic
testosterone
 Stripped of the Tour de France
Title
 July 2008…more riders
thrown out for blood doping
 The 2008 Beijing Olympics had
the most rigorous drug testing
to date.
 GENE DOPING…the next
frontier…
Mmmm…
I love
testosterone!

Missing in action
 May 2008
 An indigenous
tribe located on
Brazilian/ Peruvian
border
 Have never had
contact with others
 Breathing on one
of them could wipe
out the tribe
LISTERIOSIS OUTBREAK
 Caused by the Listeria
bacteria
 12 confirmed deaths
to date
 Michael McCain,
Maple Leaf CEO
accepted full
responisibility
GENETICALLY MODIFIED ORGANISMS
 Genetic material (DNA) has
been altered in a way that does
not occur naturally by mating
or natural processes.
 Typically genes are added to a
plant’s DNA, which produce
proteins conferring beneficial
traits, such as herbicide
tolerance (Round Up Ready)
or insect protection (Bt) to the
crop.
 Lot’s of propaganda out there!
INDONESIA’S LOST WORLD
 February 2007
 Expedition finds
dozens of exotic new
species
 The remote area is “as
close to the Garden of
Eden as you’re going
to find on earth”
ARTIFICIAL HEART
 In 2001, US surgeons
installed the world's
first self-contained
artificial heart in a
patient with heart
disease.
 Made of titanium and
plastic
 Powered by an
external battery
FACIAL TRANSPLANT
 This Chinese patient
(the victim of a bear
attack) was given not
just the lip, nose, skin
and muscle from a
donor, but even some
facial bone.
STEM CELL RESEARCH
 Nature’s master cells
 They can differentiate
into specialized cells
 Hold enormous
promise as the basis of
new cures and
treatments for diseases
 Very Controversial
(Science vs. Religion)
EVOLUTION VS.
INTELLIGENT DESIGN
Chicken-o-Saurus
One expert said that for $30 million
we could even bring a neanderthal
back to life!
CLIMATE CHANGE
 Climate change is considered by
many scientists to be the most
serious threat facing the world
today.
 The Kyoto Protocol is an
international agreement to cut
greenhouse gas emissions that
cause climate change.
 Solutions include phasing out
coal plants, expanding renewable
energy sources and public
transit, and creating new
efficiency standards for vehicles
and buildings.
HIV/AIDS PANDEMIC
 World Health
Organization (WHO)
estimate that AIDS has
killed more than
25 million people since it
was first recognized on
December 1, 1981, making
it one of the most
destructive pandemics in
recorded history.
 Scientists my have found a
weakness in the virus!!
R.I.P. “PLANET” PLUTO
 Science is not a collection of facts. It is an
ongoing process that attempts to remain in step
with the latest research. That is why scientists
sometimes change their minds!
AND REMEMBER…
