140-Million-Year-Old Spider Web Found

The oldest known spider web (to date) has been found. It's 140 million years old and it's been preserved in amber or fossilized tree sap. The amber had preserved it as it was all that time including the droplets that resemble those found in modern day webs of orb-web garden spiders (see microscopy images above). According to lead researcher Martin Brasier of the University of Oxford, the find shows the earliest webs that are incorporated in the fossil record.

The strands of fossilized spider webs were reconstructed using computer-aided technology called confocal microscopy. The findings suggest that the spiders that lived those millions of years ago also fed on insects that are the ancestors of modern day species. Other things preserved in the amber along with the webs are insect droppings, plant matter, and even microbes.

FLASH: Largest web-spinning spider discovered.

This orb-web golden spider (see video that follows) is the largest web-spinning spider ever discovered. It's as broad as an optical disc. Interestingly, the discovery is based on dead spider remains in the Smithsonian Museum of Natural History. The new species of orb-weaver spider, Nephila komaci is found to be larger than other Nephila species. For trivia's sake, you might be interested to know the largest spider in the world non-web spinning) is the Goliath Bird Eater (Theraphosa blondi).


This red-light-eyed giant tarantula spider looks real and even feels real with it's furry exoskeleton. But it's just a toy and it's remote controlled so you can scare the wits out of your friends and neighbors! Click here or on the image to place your order.

Brazilian Spider Bite Can Cure Erectile Dysfunction


It is known that the Brazilian spider (Phoneutria nigriventer) brings not only extreme pain and discomfort when it bites victims (who end up at the hospital). What's telling about each bite is that emergency staff always know if the patient has been bitten by one, particularly male patients. This is because they always have an extreme but uncomfortable erection that lasts for hours after the bite. “The erection is a side effect that everybody who gets stung by this spider will experience along with the pain and discomfort,” said study team member Romulo Leite of the Medical College of Georgia. Now, scientists have isolated the chemical that is responsible for this side effect. Dubbed Tx2-6, it is a string of amino acids called a peptide. The venom has been tested on rats whose erections were measured with a pin and it resulted in significant increases in erection levels.

There was a notable increase in nitric oxide within the cavities in the penis. When the brain senses arousal, neurons produce nitric oxide, which tells the body to produce an erection. A series of chemical reactions then occur which causes blood to rush into the male organ.

The new drug resulting from the Brazilian spider venom may soon rival Viagra in reliability and potency. However, it may still prove expensive. Well, there's always the option of allowing yourself to get bitten by a spider and get hospitalized. It happened to Peter Paker by accident and look at the boost he got! Yes, Mary Jane, you were right to choose Parker! Seriously, drugs should not be used for recreational purposes.
