When the Nose No Longer Knows
Clown fish raised in acidified waters don’t respond properly to smells.
For example, they swim toward the scent of a predator instead of away
from it.

When
infected by thorny-headed worms (the orange spot), gammarids swim
toward light. At the water's surface they become easy prey for birds,
the next creature the worm needs to infect to complete its life cycle.

The Blood Typing Game -Interactive

What happens if you get a blood transfusion with the wrong blood type?
Even though a patient's own blood type is the first choice for blood
transfusions, it's not always available at the blood bank. Try to save
some patients' lives and learn about human blood types!

Dark Energy: Is It Merely An Illusion?
Brought to you by: Eva
Changes in the rate of expansion since the universe's birth 15
billion years ago. The more shallow the curve, the faster the rate of
expansion. The curve changes noticeably about 7.5 billion years ago,
when objects in the universe began flying apart at a faster rate.
Astronomers theorize that the faster expansion rate is due to a
mysterious, dark force that is pulling galaxies apart.

A young volunteer contemplates a tempting sugary treat during an

were more likely to resist the urge to eat a marshmallow when told that
abstaining would earn them a second one.
