"The final experiments involving Alex - a grey parrot (Psittacus eithacus) trained to count objects - have just been published. They show that Alex could accurately add together Arabic numerals to a sum of eight and three sets of objects, putting his mathematical abilities on par with (and maybe beyond) those of chimpanzees and other non-human primates"

"You're running as fast as you can with your enemies in hot pursuit. Up ahead your road runs out - the landscape comes to an abrupt halt at a cliff edge. What can you do? Well, if you're a cockroach or a gecko, you keep running at full pelt into thin air, you grab the edge with your hindmost feet, you swing under the ledge and grab to the underside. You're left hanging upside down, hidden from your attacker."

"The researchers demonstrated that an "electrified" snail could be a living battery producing up to 7 milliwatts. Although the power output decreased rapidly, feeding the snail could partially refuel it straight away. Alternatively, allowing the snail to rest for about half an hour would allow it to recharge. "

"Scholars have been studying modern genetics since the mid-19th century, but even today they continue to make surprising discoveries about genes and inheritance. Here are some stats they've learned so far:"

"The Palauan jellyfish, Mastigias. The researchers placed green fluorescent dye upstream of the animal body. As the animal continued to swim, it interacted with the dye volume and pulled a volume of dye along with it. This volume of fluid moving with the animal is drift (first identified by Sir Charles Darwin, the grandson of the Origin of Species author)."

"this was from a 70's science explaination video that had a lecture for 3 minutes before it, but due to time limits, i edited it out and left the gloriously odd dancing. enjoy"

"In this activity you should use your knowledge of forces to explain how animals move! Remember that it is normally the reaction force on the body of an animal which gives rise to the resultant force. To obtain a reaction force, an action force must be applied in the opposite direction. There must be a resultant force on the body to change the velocity of the body. "

"known as the fish hawk, the osprey exhibits several adaptations to hunting and eating fish, including dense, oily plumage, large feet, scaly soles, and a reversible outer toe that helps with carrying fish through the air "

"scientists at Dalhousie University, concludes that there are about 8.7 million species on Earth. The team analyzed the numerical relationship between species, genus, family and order in well-studied life-forms and used that pattern to estimate the number of species in categories of life that haven't been well studied. Some scientists argue that that almost surely underestimates some lesser-known classes of life. Only some 1.25 million species have been described in the 253 years since Linnaeus devised the method we use to name them. This means that if there are, indeed, roughly 8.7 million species over all, nearly 90 percent of the species on Earth have not yet been discovered and described. "

" The BioDigital Human is an HTML5 bases platform for medicine and healthcare. Using 3-D, Web-GL visualization the BioDigital Human serves as an interactive tool for medical students to access complex human anatomy in a simple web browser. The surgical and disease-state animations embedded into the interface provide an interactive visual-aid for medical device and pharmaceutical sales reps to explain medical concepts to healthcare practitioners. As anatomical landmarks are paired with embedded education, instructive and training information, the BioDigital Human is the most intuitive way for data groups to organize and navigate medical information.
