I think I have this figured out ....
politicians are a bunch of rich people
convincing poor people to vote for the rich
people by telling the poor people that the
"Other" rich people are the reason they are
poor |
Late for work? Call your boss and tell
him you're not coming. He will be so
surprised when you show up that he'll
forget you were late |
If my psychiatrist said "There's really
nothing more I can do for you", that means
I'm cured right?? |
I wish people in this country would put
as much effort into earning respect as they
do demanding it |
Pato23:even Google can't answer this ur question |
7. SPITTING COBRAS EXHIBIT DEADLY ACCURACY Researchers have discovered why spitting cobras are so accurate at spraying venom into the eyes of potential adversaries. The cobras first track the movements of their attacker, then aim their venom at a predicted location where the attacker's eyes will be in the future. The ability to spray venom is a defense mechanism employed by some cobras to debilitate an attacker. Spitting cobras can spray their blinding venom as far as six feet. According to researchers, cobras spray their venom in complex patterns in order to maximize the chances of hitting their target. Using high-speed photography and electromyography (EMG), researchers were able to see muscle movements in the cobra's head and neck. These contractions cause the cobra's head to swing back and forth rapidly producing the complex spraying patterns. Cobras are deadly accurate, hitting their target nearly 100 percent of the time within 2 feet. |
6. SNAKE VENOM MAY HELP PREVENT STROKE
Researchers are studying snake venom
properties in the hopes of developing
future treatments for stroke, heart disease
and even cancer. Snake venom contains
toxins that target a specific receptor
protein on blood platelets. The toxins can
either prevent blood from clotting or cause
clots to develop. Researchers believe that
irregular blood clot formation and the
spread of cancer can be prevented by
inhibiting a specific platelet protein.
Blood clotting occurs naturally in order to
stop the bleeding when blood vessels
become damaged. Improper platelet
clotting however, can lead to heart attack
and stroke. Researchers have identified a
specific platelet protein, CLEC-2, that is not
only needed for clot formation but also for
the development for lymphatic vessels.
Lymphatic vessels help to prevent swelling
in tissues. They also contain a molecule,
podoplanin, that binds to the CLEC-2
receptor protein on platelets similarly to the
way snake venom does. Podoplanin
promotes blood clot formation and is also
secreted by cancer cells as a defense
against immune cells. Interactions between
CLEC-2 and podoplanin is thought to
promote cancer growth and metastasis.
Understanding how toxins in snake venom
interact with blood may help to develop
new therapies for those with irregular
blood clot formation and cancer. |
5. DINOSAUR-EATING SNAKE
Researchers from the Geological Survey of
India have discovered fossil evidence that
suggests that some snakes ate baby
dinosaurs. The primitive snake known as
Sanajeh indicus was about 11.5 feet long.
Its fossilized skeletal remains were found
inside the nest of a titanosaur. The snake
was coiled around a crushed egg and near
the remains of a titanosaur hatchling.
Titanosaurs were plant-eating sauropods
with long necks that grew to an enormous
size very quickly.
The researchers believe that these dinosaur
hatchlings were easy prey for Sanajeh
indicus. Due to the shape of its jaw, this
snake was unable to consume titanosaur
eggs. It waited until the hatchlings emerged
from their eggs before it devoured them.
Although originally discovered in 1987, it
wasn't until years later that the fossilized
nest was recognized to include the remains
of the snake. Paleontologist Jeff Wilson
states, "Burial (of the nest) was rapid and
deep, probably a pulse of slushy sand and
mud released during a storm caught them
in the act." The discovery of the fossilized
nest gives us a glimpse of a moment in time
during the Cretaceous period. |

4. BOA CONSTRICTOR REPRODUCES WITHOUT SEX Some boa constrictors don't need males to reproduce. Parthenogenesis has been observed in these large reptiles. Parthenogenesis is a form of asexual reproduction that involves the development of an egg into an individual without fertilization. The female boa constrictor studied by North Carolina State University researchers has had offspring through both asexual and sexual reproduction. The baby boas that were produced asexually however, are all female and bear the same color mutation as their mom. Their sex chromosome make up is also different from the sexually produced snakes. The asexually produced baby boas have (WW) chromosomes, while the sexually produced snakes have either (ZZ) chromosomes and are male or (ZW) chromosomes and are female. Scientists don't believe that this type of rare birth is due to changes in the environment. According to researcher Dr. Warren Booth, "Reproducing both ways could be an evolutionary 'get-out-of-jail-free card' for snakes. If suitable males are absent, why waste those expensive eggs when you have the potential to put out some half-clones of yourself? Then, when a suitable mate is available, revert back to sexual reproduction." The female boa that produced her young asexually did so in spite of the fact that there were plenty of male suitors available. |
3. SNAKE STEALS VENOM FROM TOXIC TOADS
A species of non-poisonous Asian snake,
Rhabdophis tigrinus, becomes poisonous
due to its diet. What do these snakes eat
that allow them to become poisonous?
They eat certain species of toxic toads. The
snakes store the toxins obtained from the
toads in glands in their neck. When facing
danger, these snakes release the toxins
from their neck glands. This type of defense
mechanism is seen in animals lower on the
food chain, including insects and frogs, but
rarely in snakes. Pregnant Rhabdophis
tigrinus can even pass the toxins on to their
young. The toxins protects the young
snakes from predators and lasts until the
snakes are able to hunt on their own.
