The idea of a fish being able to generate electricity strong enough to light lamp bulbs--or even to run a small electric motor--is almost unbelievable, but several kinds of fish are able to do this. Even more strangely, this curious power has been acquired in different ways by fish belonging to very different families.

Perhaps the best known are the electric rays, or torpedoes, of which several kinds live in warm seas. They possess on each side of the head, behind the eyes, a large organ consisting of a number of hexagonal shaped cells rather like a honeycomb. The cells are filled with a jelly-like substance, and contain a series of fiat electric plates. One side, the negative side, of each plate, is supplied with very fine nerves, connected with a main nerve coming from a

One of the most interesting experiments in electronic communication I’ve ever seen is coming from Wave. It’s real-time e-mail. What that means is that as you’re typing a message in Wave, either a new message or a reply, the person you’re writing to can see what you’re typing as you type it. Sounds awful, right
You don’t have to use Wave in this real-time way. It also works as a standard e-mail. What’s really different about Wave is that if you’re replying to a message and the person you’re replying to happen to be online, they can jump into the conversation at that point, and change what is an e-mail conversation into an instant message conversation or a chat.
Wave right now is still closed to most users. And Wave isn’t yet connected to other communication systems, like regular e-mail, which means that the only people we can Wave with are other people on Wave as well. So we don’t yet know what using Wave will be like
A. It makes people see each other online.
B. It enables people to send real-time e-mails.
C. It allows you to send more e-mails at the same time.
D. It can be easily connected to other communication systems.

If asked, "What are health decisions ", most of us would answer in terms of hospitals, doctors and pills. Yet we are all making a whole range of decisions about our health which go beyond this limited area; for example, whether or not to smoke, exercise, drive a motorbike, or drink alcohol really. The ways we reach decisions and form attitudes about our health are only just beginning to be understood.

The main paradox is why people consistently do things which are known to be very hazardous. Two good examples of this are smoking and not wearing seat belts. Both these examples underline elements of how people reach decisions about their health. Understanding this process is crucial. We can then more effectively change public attitudes to hazardous, voluntary activities like smoking.
