Plant Sciences, Zoology & Evolution / Trees - How do they exist?
« on: 20/02/2007 17:14:04 »
Quote from: another_someone on 18/02/2007 02:48:18

To ask 'how are they alive', you must first answer 'what is life?'.

The common definition for life, as I see it, seems to be vaguely around the ability to reproduce in an inexact but inheritable way (i.e. each generation is subtly different from the previous, but the changes that occur from one generation to the next is then passed on to subsequent generation). 

Sorry George, gotta problem with 'each generation is subtly different from the previous'. What about Amoebae that reproduce by binary fission? They are most definitely alive. I would suggest that this should be rephrased to 'the ability to reproduce'. This led me to discussions/arguments with my academic tutor when I was an undergraduate, over whether viruses were 'alive'. He said they weren't because they couldn't reproduce without 'hijacking' another living cell, I said they were because that meant they reproduced!

Physiology & Medicine / What is colourblindness, and what's it like to be colourblind?
« on: 20/02/2007 17:01:14 »
Another interesting point, more men than women are colour blind.

General Science / Why do we have a preference?
« on: 20/02/2007 16:06:26 »
Left or right side of the bed doesn't worry me. For some reason I prefer the side nearest the door.

It may be that for married people there is a territorial thing about his and her side of the bed, or it could be just that I like greater variety than other people.

What about co-habiting?  [:P]

There is a condition called Seasonal Affective Disorder (SAD) that is depression during the shorter/darker days of winter. Exposure to sunlight (eg going outside at lunchtime or using a special lamp) can help alleviate/overcome this problem.

Physiology & Medicine / Dermatology - what are spots and pimples? How can they be cured?

... but the principle is similar to the use of blue-dominated lights in toilets to prevent drug addicts from shooting up.

Eh??? Please can you explain this Chris.

Physiology & Medicine / Different blood types - What are they ?
« on: 03/02/2007 16:46:03 »
Just a quick add on re blood groups A, B and 0. The 0 actually stands for 'zero' (ie neither A nor B antigens are present) although we all tend to call it 'OW' Someone with blood group 0 is known as a universal donor because people with the other blood types (A, B or AB) can receive transfusions from blood group 0 (providing the rhesus factor is compatible).

For  other organ transplants (ie solid organs rather than blood) there needs to be a much tighter compatibility, not just the A,B,0 blood groups. We all thave markers on our cells that identify them as ours, not foreign. This is known as the Major Histocompatibility Complex (MHC). For organ transplants these must match as closely as possible or the recipient's immune system will identify the different MHC as foreign and attack it. This is what organ rejection is and is why close relatives usually make the best donors (similar genetic makeup). This is also why recipients often take immunosupressor drugs to help prevent rejection. 

It's also important to 'wash out' donor blood from the organ before the transplant, particularly a type of white blood cell called T cells.

That CAN'T be true! / humans
« on: 03/02/2007 16:24:13 »
I don't think it's a question of 'good' and it depends what you mean by 'superior'. IF there are/have been/will be more 'superior' beings some where/when/how, being able to perceive them MAY or may not use other senses than we use/have. To a certain extent it depends on what you actually mean by your question.

I heard that L Ron Hubbard had a bet with a fellow science fiction writer that he could start a religion - scientology was the result.
