I need your help. What topics in biology are interesting enough as to research journals and write about? I have a senior seminar presentation that am meant to discuss a biology topic and yet there are so many that am so confused. Any ideas please?

There seems to be an area of India where gravity is less strong than anywhere else. Should it be constant all over?

I know what happens to a dead body, the sweeling and generally ick. But if someone just immersed themselves in water, with proper breathing devices, and no protection. How would it affect them? They have water, food, and waste facilities. I looked up why skin wrinkles and shipwreck survivors and immersion tanks with little help to my question. And hypothetically this is clean water, not dirty water so I don't think the water torture stuff applies.

How does it make things white, and how does it kill germs?

Don't be afraid of being scientific in your answer.

I've done my fair share of chemistry but I can't remember anything about bleach, besides something to do with Chlorine ions.

*BONUS QUESTION*: Do you like the smell of bleach? (some people do; I'm undecided)

If I complete 3 years of experience working as a clinical lab tech, take chemistry/biochem/biology free online courses offered by major universities such as MIT's at http://ocw.mit.edu/OcwWeb/Global/all-courses.htm#Biology , If I complete an associates degree in Medical lab, and if I have a BS degree in computer engineering.

Any comments will be greatly appreciated

A portion of a uniform chain of length 8 ft is loosely coiled around a peg at the edge of a high horizontal platform, and the remaining portion of the chain hangs at rest over the edge of the platform. Suppose the length of the overhanging chain is 3 ft, that the chain weighs 2 lb/ft, and that the positive direction is downward. Starting at t = 0 seconds, the weight of the overhanging portion causes the chain on the table to uncoil smoothly and to fall to the floor. If x9t0 denotes the length of the chain overhanging the table at time t > 0, then v= dx/dt is its velocity. When all resistive forces are ignored, it can be shown that a mathematical model relating v to x is given by xv(dv/dx + v ^2= 32x.
a) Rewrite this model in differential form. Proceed as in Problems 31- 36 and solve the DE for v in terms of x by finding an appropriate integrating factor. Find an explicit solution v(x).
b)Determine the velocity with which the chain leaves the platform. (and there is a platform

MPs will tomorrow debate scrapping Greenwich Mean Time and aligning British clocks with mainland Europe.

Why??? Does a one hour difference really make a massive change for 6 months of the year?

It's the things like GMT that give us that slight edge. The fact that in some way we could be classified as the centre of the earth, there are countries ahead of us in time (+GMT) and some behind (-GMT). It's a shame that these things we are losing because of pathetic people in positions they deserve not to be in!

I live in an urban area in Southern California. I have visited websites about tardigrades ("water bears") and, though they say that tardigrades can be found worldwide, they do not say where specifically. If I were to collect some moss in my local San Gabriel mountains, would I find tardigrades? How about if I collected some wet earth/moss in my backyard? Has anyone heard of someone in the San Gabriel Valley finding tardigrades?
