Maps and Time lines of plants, insects, sm. animals, and terrain.
I am looking to assemble a wide verity of information grouped together covering a certain area of land.
Along the border of China and Mongolia. 100 miles south of border to north 200 miles inside Mongolia From western border to eastern border
All from the time of 125 million to 300 million years ago.
Maps and graphs containing:
-Topographical : - Terrain
- Water levels highs and lows - Some research sight (containing programs as to what the place looked like back then-Time lines of : - insects (paleontology)
- sm. animals - fossils - charts graphsWHY:
First Flower PBS Airdate: April 17, 2007 Professor Sun Ge, from China's Jilin University, is certain that early flowers evolved here, in northern China, and he is determined to find the world's first.
Not far from the border of Inner Mongolia, there is a remarkable fossil site that is revealing what the Earth looked like more than 100,000,000 years ago.

Insanity
I don't know a lot about psychology (I got as far as AP psych in high school, so I know the basics), but I've recently gotten curious about how people go crazy. Since I don't have much background in the area, I don't where to go to learn about it. Any ideas? Also, as a subquestion, does insanity universally degrade a person's ability to succeed, or are there cases of people who become smarter, more creative, what-have-you after losing it than they were before?

Entropy and Creationism
A common argument for Creationism is that as entropy can only increase there must be a start where everything is in order, which is when God created the universe. What is a rebuttal for this argument? How come entropy was so low after the Big Bang? --antilived T | C | G 07:38, 12 May 2008 (UTC)

Michelson Interferometer
If the mirror is moved away then the number of fringes appearing in the microscope would change or not? If so then it is because the length of path is changing and so fringes are closely spaced.
Aloe Vera
I have been told that Aloe Vera Gelly will kill ear mites in dogs. Can anyone confirm this? Mr Beans Backside (talk) 10:12, 12 May 2008 (UTC)

As it is scientifically proven that humans emit carbon dioxide, the best way to reduce CO2 emissions is to engage in genocide of the human race.--WaltCip (talk) 12:59, 13 May 2008 (UTC)
I know someone mentioned this above, but I'm not sure it was taken seriously - eating vegetarian is probably the most influential thing a person can do to personally reduce climate change - according to a recent UN report, http://www.un.org/apps/news/story.asp?NewsID=20772&Cr=global&Cr1=environment, "Cattle-rearing generates more global warming greenhouse gases, as measured in CO2 equivalent, than transportation". Pretty impressive. --Bmk (talk) 19:20, 13 May 2008 (UTC)
Protoplast fusion
while performing protoplast fusion we have to chop leaves into very fine peices before proceeding for actual fusion. so why don't the cells die out at that moment?--Kayatheangel (talk) 13:19, 12 May 2008 (UTC)
Finding CpG islands with genomic databases
How do I determine which area of a gene can be designated 'CpG' island? Suppose that I'm interested in this gene; I vcan see that it has a lot of CpGs but can I get a program (preferably online) that defines the CpG island(s)? ----Seans Potato Business 13:34, 12 May 2008 (UTC)

- Or, normally, you can go to the contig viewer in Ensembl , go to the "detailed view" section and in the menu bar, click on the "features" tab. The check the "CpG island" check box, close the tab, it you should see a track on the viewer showing islands in the context of your gene. Ensembl seems to be having technical issues at the moment, and it finds an error when I do it, but it should be working again soon. Rockpock e t 19:47, 12 May 2008 (UTC)
Widely-distributed, semi-technical history of moon shot?
Was there anything like the Smyth Report for the Apollo program, or for the Apollo 11 mission (moon landing) specifically? The Smyth Report was a government-produced history of the atomic bomb that came out contemporaneously with its use, to explain in more detail what people were seeing on the front pages of newspapers after the bombings of Hiroshima and Nagasaki. Anything like that for the space race? I don't mean official histories that came out years later, or unofficial histories/popularizations. --140.247.242.128 (talk) 17:16, 12 May 2008 (UTC)

Earthquakes
I understand how earthquakes start - the release of pressure from two tectonic places which are pushing against each other or rubbing across each others boundary's - but how do earthquakes stop? What stops the plates from continuing to move? Mr Beans Backside (talk) 18:08, 12 May 2008 (UTC)

Male to female ratio
Human offspring are roughly balanced 50% male to 50% percent female. Does this balance exist throughout nature, or has evolution resulted in more useful proportions for some species? For example, more male dear because some might die fighting each other. If proportions are unbalanced in some species, how does this work? Mr Beans Backside (talk) 18:45, 12 May 2008 (UTC)
Does the universe spin?
The planets, solar systems, star clusters, and galaxies all spin. Does the universe itself spin? Mr Beans Backside (talk) 19:58, 12 May 2008 (UTC)

shortwave radio
hi, I am interested in buying a shortwave radio (not to transmit just to receive) but am interested in hearing ham radio too.
I am confused as to if i need ssb (short sideband??) with also usb, lsb and cw.
can someone clarify? also can i spend $100/£50 rather than a lot , if so please post a link.
thx
Ordinary cheap shortwave receivers will have a difficult time picking up amateur radio signals. The problem is that the normal broadcast stations have a much stronger signal which will cause the weak HAM radio signal to become swamped in intermodulation noise. You need a more expensive communications receivers to be able to enjoy listening to HAM radio. If you want a good deal, you should try to get hold of a second hand communications receiver. There are many exellent communications receivers that are no longer manufactured that would cost you $1000 or more if bought new. But the second hand price will be significantly lower. E.g. why no
