Any mad scientists planning to genetically engineer Dracula this Halloween should look to the vampire bat for inspiration. New research pinpoints some of the genetic changes that allowed them to evolve to subsist on a diet of pure blood.

Key among those is a knack for keeping their meals from coagulating. They do so with the help of a gene found in other animals - plasminogen activator. In humans the gene protects against heart attack by producing proteins that bust up blood clots and clear vessels. Previous research had shown that vampire bats activate the gene in their saliva, too.

However, the small, winged mammals, which live in the tropics of North and South America and gorge on blood from birds and livestock, have made other modifications to plasminogen activator (PA) since they split off from fruit and insect eating bats, says David Liberles, a geneticist at the University of Wyoming in Laramie.

His team studied three species, each with its own take on vampirism. Hairy-legged vampire bats victimise only birds, while its cousin, white-winged vampire bats, prey on birds and mammals. Just one species, the common vampire bat, feeds exclusively on mammals. It prefers to bleed cattle and other livestock, but humans- especially who sleep outside - also fall victim to its bite.

E-learning includes all forms of electronically supported learning and teaching, including educational technology. The information and communication systems, whether networked learning or not, serve as specific media to implement the learning process. This often involves both out-of-classroom and in-classroom educational experiences via technology, even as advances continue in regard to devices and curriculum. Abbreviations like CBT (Computer-Based Training), IBT (Internet-Based Training) or WBT (Web-Based Training) have been used as synonyms to e-learning.


E-learning is the computer and network-enabled transfer of skills and knowledge. E-learning applications and processes include Web-based learning, computer-based learning, virtual education opportunities and digital collaboration. Content is delivered via the Internet, intranet/extranet, audio or video tape, satellite TV, and CD-ROM. It can be self-paced or instructor-led and includes media in the form of text, image, animation, streaming video and audio.


It is commonly thought that new technologies can make a big difference in education. In particular, children can interact with new media, and develop their skills, knowledge, perception of the world, under their parents' monitoring, of course. Many proponents of e-learning believe that everyone must be equipped with basic knowledge of technology, as well as use it as a medium to reach a particular goal.


E-learning is naturally suited to distance learning and flexible learning, but can also be used in conjunction with face-to-face teaching, in which case the term Blended learning is commonly used. E-Learning pioneer Bernard Luskin argues that the "E" must be understood to have broad meaning if e-Learning is to be effective. Luskin says that the "e" should be interpreted to mean exciting, energetic, enthusiastic, emotional, extended, excellent, and educational in addition to "electronic" that is a traditional national interpretation. This broader interpretation allows for 21st century applications and brings learning and media psychology into the equation.


In higher education especially, the increasing tendency is to create a Virtual Learning Environment (VLE) (which is sometimes combined with a Management Information System (MIS) to create a Managed Learning Environment) in which all aspects of a course are handled through a consistent user interface standard throughout the institution. A growing number of physical universities, as well as newer online-only colleges, have begun to offer a select set of academic degree and certificate programs via the Internet at a wide range of levels and in a wide range of disciplines. While some programs require students to attend some campus classes or orientations, many are delivered completely online. In addition, several universities offer online student support services, such as online advising and registration, e-counseling, online textbook purchase, student governments and student newspapers.


E-Learning can also refer to educational web sites such as those offering learning scenarios, worksheets and interactive exercises for children. The term is also used extensively in the business sector where it generally refers to cost-effective online training.
