What a wonderful page you have here. I have just finished reading all the comments and have enjoyed them all. Its better than buying the New Scientist which I buy once a month... I find the facts fascinating.. keep it up

Hopefully not in front of a class first time Appy! Do you know of an 'interesting' way to talk about back emf? Or is it just chalk and talk??? It's one thing to know this stuff, it's quite another to come up with a way to teach it!

hi Andre
Still struggling with my assignment so nothing interesting today....

well I wonder if I can come up with an ans for your query Suzy, for I am no good in teaching (personally I feel that way!)something to do with my temper perhaps..mmm back emf or counter emf varies with the load ,the more the load min the back emf..dunno how you will make it interesting!! will just chk the net for your sake..havent done any subject related search so far..

Recent research on the diminishing population of Eagles/Vultures in our state reveals a shocking fact.The reason for the extinction of these birds is renal failure caused by a chemical called cadmium.
The cattle population in the rural area when sick are given shots of pain killers which has More...

But then if you look at the equation of risk virsus cure, this factor is overlooked perhaps.
(up to some extent)For example, I take a banned drug(yes not ashamed in accepting it) for my migraine.I am very well aware of the side effect. but still the present good living is also important for me.

Hi, appy and Suzy and Andre (sorry, I forgot how to make your accent mark)! Wow! This is a VERY interesting "Forum" page! Thank you for starting and contributing to it! I guess I should visit more often!

I saw a headline: 200-pound dinosaur skull found. Well that's huge so I wanted to find out more. It has been named Gryposaurus monumentensis (I had to copy-paste that name), is a duck-billed dinosaur, and it was found in Utah. What I couldn't find out was if it was the whole dinosaur that was More...

I agree that a 200-pound seem amazing, but that "monumentensis" part of the name suggests it's extremely large! Two hundred pounds for the entire skeleton, on the other hand, seems rather small, relatively speaking.

Hi, Suzy. Here's more information:

The Gryposaurus monumentensis is a newly discovered dinosaur that roamed the Earth 75 million years ago, devouring everything in its path.

The 9m (29ft) long gryposaurus monumentensis had 300 teeth, with 500 more 'stored' in its head, ready to More...

Here's a website with more information about Gryposaurus monumentensis:

Here's the rest of the article:

The heftiness of G. monumentensis poses several problems for paleontologists trying to envision what North America looked like 75 million years ago. How the massive duckbill could survive alongside other giants, and why it didn't mingle even with its own More...

Thanks Julie! That was amazing! Even though this dinosaur was a plant eater, it sounds like it would be terrifying to encounter one....

The Nobel Prize for medicine was announced and was awarded for the process of gene targeting - removing a gene and replacing it with another (how's that for oversimplification?!) One of the winners was 82 - imagine being that productive at that age!

Scientists have discovered that elephants in Africa will run away if they hear the sound of buzzing bees. African honeybees are apparently extremely aggressive and their stings are very painful. The scientists are proposing placing hives near farmland to deter elephants from damaging crops, More...

Thank you Julie. It is so interesting to read about the past history of life..and I'm glad that I wasn't around in those days either!!

The latest issue of Current Science, the international science journal, reports the finding of the smallest known land vertebrate in India, a miniature frog, from Kurichiyarmala in Kerala’s Wayanad district on the Western Ghats of peninsular India. This new species of frog, measuring only between More...

so balanced the page with that post.:)

Nobel prize ,well a tongue-in -cheek homage to the real Nobel laureates ,the awards for bizarre research and inventions has been announced, the Igs being chosen by the Annals of Improbable Reaearch magazine. Some scientists have objected this, stating that it tarnish the legitimate research.But others say a sense of fun humanizes the scienists.

The highly coveted peace prize was awarded to u.s.

We watched an interesting program on Public TV the other night. They talked about how man had started in Africa. From there he wandered into other parts of the earth. One of the first places he went to was Australia. One small part of the program was about Nomads that live in the Northern More...

The Nobel Prize for Physics has now been announced. Two physicists identified idependently the physical effect called giant magnetoresistance. It is this effect that allows computers to store huge amounts of information. Yay for giant magnetoresistance!! p.s. The is about a small change magnetism causing a greater change in electrical resistance.

hi Debby
I start to shiver at 12 deg C!! I can't imagine those kinds of temperatures, in either C or F!

Hi Suzy - When they sleep in the 2nd tent, they use no blankets, just their clothes. Unbelievable! It makes me cold just to think about it. There were only 9 people in this one particular group. I thought it seemed very small. I can't imagine a baby surviving in that climate!

The program was very interesting. They were following a certain "lineage" of people by testing "DNA."

I am amazed at how much info those "memory sticks" hold. My DIL is an artist who "blows glass." She takes pictures of her items and puts them on memory sticks. Technology has come so far. It is hard to keep up with everything.

And now the Nobel prize for Chemistry - awarded for studies of chemical reactions on solid surfaces. One of the results of Gerhard Ertl's research has been an understanding of the thinning of the ozone layer. According to the Associated Press: "Ertl’s research laid the foundation of modern More...

Science scores another Nobel with the Nobel Peace prize going to Al Gore and the United Nations' Intergovernmental Panel on Climate Change (IPCC)for their work raising awareness of the problem of climate change. See http://news.ninemsn.com.au/article.aspx?id=305293 for a list of Nobel Peace prize winners since 1980...

I was trying to decide how science could score the Nobel for literature which was awarded to British writer Doris Lessing for 'five decades of epic novels that have covered feminism and politics, as well her youth in Africa.' Perhaps we could claim that the fact the a woman won as scientific proof More...

Madame Curry? I think she had something to do with the x-ray?

That is intersting, Suzy. Thanks for the info!

Human digits came from fish..... a palaeontologist at London's Natural History Museum, said the small fin bones of the Queensland lungfish are much the same as fingers and toes in modern back-boned land animals. Unfortunately the palaeontologist also said "We have a case of fish fingers in the Queensland lungfish" Groan!!!

The Queensland lungfish is known as a living fossil because it has survived since first appearing on the fossil record more than 100 million years ago.

A headline in Newsweek: Free the Asteroid! (It Didn't Kill the Dinosaurs) Apparently the timing is off.

Why is it that some of the best inventions are the result of research for war?

I heard something the other day that I hadn't heard before. I heard the world was knocked about 3 degrees off of its axis when the earthquake hit that caused the Sunami. Has any one else heard any thing about this? I thought it was interesting. Of course, if it did happen, it would explain some of the weird weather we have been experiencing.

Hi Debby, I googled 'earth axis earthquake' and found this article - though it's mostly about time changes rather than movement of the axis..
